Asphalt crack filler machine can only be recognized by customers when its use effect is good, so how to improve the construction effect of asphalt crack sealing machine? Good equipment does not necessarily have a good effect. It is necessary to choose a good filling material and master the filling skills. Below I have summarized the methods to improve the construction effect of the crack sealing machine.
Choose the appropriate filling time of the asphalt crack sealing machine. In order to achieve good results and better protect the pavement, it must be sealed shortly after the cracks are formed. In fact, most owners start to consider grouting construction only after a certain number of cracks on the road surface. It is recommended to start the grouting treatment when the crack width reaches 3mm. It is better to use grouting in spring or autumn. When used in winter, the asphalt coating will not be easy to dry for a long time, which will affect the opening time of the road section. In addition, it is necessary to choose a time when the weather is sunny for filling and construction. Avoid construction on cloudy and rainy days, so as not to affect the construction effect.
Correctly operate the asphalt crack sealing machine. When using a seam crack sealing machine, you first need to use a road slotting machine to slot the cracks according to the design requirements, adjust the slotting width of the slotting machine, and move along the centerline of the crack as much as possible. Make both sides of the crack have been cut, remove the aging material on the edge of the crack, and expose the new surface on both sides of the crack, to ensure that the asphalt pavement joint glue and the road surface can be better combined. While grooving in front of the grooving machine, use a road blower to sweep the cracks immediately afterward to clean up the dust, debris, and loose bodies around the cracks to ensure the cleanliness of the cracks. Check whether the bottom of the crack and the crack wall is wet. If it is obviously wet, you need to use a hot air spray gun to dry the cracks. The heated road cracks will slightly become black and hot. Carry out the filling and sealing of small bituminous joint glue. It is necessary to heat the asphalt pavement joint grouting glue to a temperature between 185°C and 195°C to completely melt and then perform the joint filling and sealing work.
First use a small asphalt crack filling machine to heat, stir, and melt the asphalt pavement grouting glue, and then transport it out through the asphalt pump pipeline and pour it into the cleaned slot. The filling work should be carried out continuously, and the grooves should be fully filled from bottom to top, and air bubbles should be avoided in the lower part of the packing. After the cracks are poured, the post-construction maintenance should be done. After the cracks are poured, the asphalt pavement joint glue is usually fully solidified before allowing traffic, usually about 20 minutes. This time will vary depending on the temperature of the construction site. If you are eager to release traffic, you can also sprinkle fine-grained materials such as river sand, lime, steel sand, etc. after filling the asphalt pavement joint glue, so that traffic can be released without waiting.
How to repair road cracks? As we all know, after cracks appear on the pavement, the cracks can only be solved by repairing the cracks. Long-term wind and sun and rolling on concrete pavements or asphalt pavements will inevitably cause various cracks and damages, so how to repair this problem? Which repair equipment should I choose?
There are many types of asphalt crack filler machines, and different types of crack sealing machine correspond to different fields. Asphalt joint filling machine is a commonly used joint filling machine designed for asphalt roads. After the asphalt road is aged, it will become rough and crisp, and some slight cracks will appear on the surface. the road will become soft and fragile, the water permeability coefficient will increase, and the disease resistance will below. At this time, we will use our asphalt crack filler machines for repair.
The correct use steps of asphalt filling machine:
1. First, according to the design requirements, use a road slotting machine to slot the cracks, adjust the slotting width and depth of the slotting machine, and try to move along the middle of the crack, so that both sides of the crack are cut and removed The aging material at the edge of the crack exposes the new surfaces on both sides of the crack to ensure that the asphalt pavement joint glue and the road surface can be better combined.
2. While grooving in front of the grooving machine, use a road blower to sweep the cracks immediately afterward to clean up the dust, debris, and loose bodies around the cracks to ensure the cleanliness of the cracks.
3. Check whether the bottom of the crack and the wall of the crack is wet. If it is obviously wet, you must use a hot air spray gun to dry the cracks. The heated road cracks will slightly become black and hot.
4. The working process of filling and sealing small bituminous joint glue. It is necessary to heat the asphalt pavement joint glue to be completely melted between 185°C and 195°C before filling and sealing the joint. First, use an asphalt filling machine to heat, mix and melt the asphalt pavement joint glue, and then transport it out through the asphalt pump pipeline and pour it into the cleaned slot. The filling work should be carried out continuously, and the grooves should be fully filled from the bottom up, and air bubbles should be avoided in the lower part of the packing. After the cracks are poured, the asphalt pavement joint glue is usually fully solidified before opening traffic, usually about 20 minutes, this time will vary depending on the temperature of the construction site. If you are in a hurry to open up traffic, you can also sprinkle fine-grained materials such as river sand, lime, steel sand, etc. after filling the asphalt pavement joint glue, so that traffic can be opened without waiting. When working with the asphalt filling machine, you must pay attention to safety. Wear a mask to prevent the inhalation of harmful gases!
The shot blasting machine uses a high-speed rotating impeller to throw small steel shots or small iron shots out to hit the surface of the part at high speed, so the oxide layer on the surface of the part can be removed. At the same time, steel shot or iron shot hits the surface of the part at a high speed, causing the lattice distortion and deformation of the surface of the part, which increases the surface hardness. It is a method of cleaning the surface of the part. Shot blasting machine is often used to clean the surface of the casting or strengthen the surface of the part. deal with.
A Sandblasting machine is a method of using compressed air to blow out the quartz sand at high speed to clean the surface of the part. It is also called sand blowing in the factory, which not only removes dust but also removes oil incidentally, which is very useful for painting. It is often used to remove rust on the surface of parts; to modify the surface of parts (the small wet sandblasting machine sold in the market is for this purpose, the sand is usually corundum, and the medium is water); in the steel structure, the application of high-strength bolts for connection is relatively advanced Since the high-strength connection uses the friction between the bonding surfaces to transmit force, the quality of the bonding surface is very high. At this time, the bonding surface must be treated with sandblasting. Sandblasting is used for complex shapes, easy to manually remove rust, low efficiency, poor site environment, and uneven rust removal.
What are the differences?
The main function of anautomatic sandblasting machine is to remove rust and scale on the surface, such as parts after heat treatment, and the role and function of the floor shot blaster are more: not only removes rust, removes surface oxide scale, but also improves surface roughness and removal Parts-machining burrs can eliminate the internal stress of the parts, reduce the deformation of the parts after heat treatment, and improve the surface wear resistance and pressure capacity of the parts.
There are many processes used for shot peening, such as castings, forgings, parts after machining, and parts after heat treatment.
Thesand blaster machineis mainly operated manually, while the shot blasting machine is more automatic and semi-automatic.
The steel shots and iron shots used by the floor shot blaster are not actually shots in the true sense. To be precise, they are small steel wires or small steel rods. They only look like balls after a period of use. The so-called sandblasting To put it bluntly, sand is just river sand. It is no different from that used for construction, except that the sandblasting is screened, contains less mud, and has a particle size specification. Of course, some industries are also different. For example, a real steel shot is used for shot blasting in the shipbuilding industry, and metal ore (not river sand-quartz sand) is used for sandblasting.
The portable shotblasting machine uses compressed air as the power to spray sand or pellets onto the surface of the material to achieve removal and certain roughness. The floor shot blaster is a method that uses the centrifugal force generated when the shot material is rotated at a high speed to impact the surface of the material to achieve removal and a certain roughness.
The shot blasting machine is a device that uses the component of the shot blasting device to throw the projectiles at high speed, so as to achieve the purpose of cleaning or strengthening the surface. Generally speaking, this equipment can be used for de-coring, cleaning, and sand falling treatment at the same time. In many places, this equipment will be called a sandblasting machine or a sandblasting machine. Below, the shot blasting machine manufacturer YG Machinery will explain the main functions and application fields of the shot blasting machine.
1. Main functions
It can remove the oxide scale or sticky sand on the surface of cast steel and cast iron, which can clean up the surface of the casting. It is also a necessary step for the quality inspection of the casting. The casing of large steam turbines should go ahead. Flaw detection can only be carried out after shot blasting to ensure reliable results. The hook type shot blasting machine is divided into single hook and double hook. The hook type shot blasting machine uses two hooks to load workpieces into the shot blasting room alternately. Use a shot blasting machine to throw 0.2-0.8 shots to the surface of the workpiece to make the surface of the workpiece reach a certain roughness, make the workpiece beautiful, or change the compressive stress of the workpiece to increase its life. For castings, shot blasting is a necessary process to find defects such as peeling and subcutaneous pores on the surface. Shot blasting can ensure that the castings have a higher quality.
In modern metal strength theory, as long as the internal dislocation density of the metal is increased, the strength of the metal can be improved, and the use of a shot blasting machine to perform shot blasting on the metal can enhance its dislocation structure. Can help improve the strength of the metal, this method is very effective for those hardened metals that cannot use phase change.
Through the shot blasting, compressive stress can be formed on the surface of the casting, which can increase the tensile strength, corrosion resistance, and fatigue strength of the casting, and can also correct those thin-walled castings that are distorted, which can replace ordinary hot and cold forming The process of processing large thin-walled castings to avoid those residual tensile stresses to obtain beneficial compressive stresses.
2. Field of application
1. It can be used in the manufacture of bearings. Generally speaking, the bearing surface is required to be smooth. Shot blasting can be used to remove burrs and impurities. According to modern metal strength theory, increasing the dislocation density inside the metal is the main direction to improve the strength of the metal. The practice has proved that shot blasting is an effective process to increase the metal dislocation structure.
2. It can be used in shipbuilding. Most of the steel plates used in shipbuilding have rust, and the rust removal operation can be done well by using shot blasting.
3. It can be used in the manufacture of automobiles. Many steel plates and castings used in automobiles require polishing, but they need to be able to maintain the original shape and strength of the plate. The shot blasting method can be used to polish without physical damage. . Shot blasting machine accessories can be used to remove burrs, diaphragms and rust, which may affect the integrity, appearance, or definition of parts of the object. The shot blasting machine can also remove surface contaminants from a partially coated surface and provide a surface profile that increases the adhesion of the coating to achieve the purpose of strengthening the workpiece.
4. It can be used in the manufacture of hardware products. Shot blasting can meet the requirements of flat, smooth, and clean hardware.
5. It can be applied to the field of electroplating. The requirements of electroplating are similar to those of hardware, and of course, it can also be used for processing.
6. It can be used in the field of motorcycle accessories manufacturing, usually using roller-type equipment to complete the shot blasting operation.
In addition to the above, the shot blasting machine can also be used in the field of steel plate manufacturing to deal with problems such as burrs on newly-fired steel plates. It can also be used in the field of valve manufacturing to grind and polish valve castings to achieve product quality. Requirements.
With the continuous progress of society and the continuous development of science and technology, the performance of small road rollers is also constantly improving. This improves operational efficiency to a certain extent and reduces construction costs. However, it is still encountered when using mini road rollers. For some common problems, there are still more or fewer doubts.
What are the common types of small road rollers?
Small road rollers are commonly used construction machinery, suitable for compacting soil and roadbeds, and are widely used in road infrastructure construction, road repairing, dam building, construction, and other industries. There are many types of mini road rollers, and different types of road rollers have different working principles.
1. The vibratory road roller is flexible and has a good compaction effect. It can compact coarse-grained paving materials and asphalt mixture pavements, and can also be used to compact concrete pavements.
2. The ride-on roller has the characteristics of simple structure, strong climbing ability, and high productivity. It is especially suitable for the sub-layer compaction of different soil, gravel, gravel, and other materials in water conservancy and road engineering. It is ideal for dam and roadbed backfilling projects. Compaction equipment.
3. The unit line pressure of the vibratory road roller is large, the vibration force is deeply affected, and the compaction depth increases, which can reduce the number of compaction passes. It is most suitable for compacting non-cohesive soil, gravel, block stone, rockfill, asphalt concrete and asphalt pavements of different types and thicknesses.
What are the characteristics of mini road rollers?
Among the compaction equipment, the compact road roller is small in size, compact in structure, easy to transport, powerful in work, and high inefficiency. It can also be used with large road rollers. The adjustable and foldable operating handle brings a comfortable operating environment to the operator. In addition, it is very flexible and can be applied to various road sections.
What is the scope of use of the small roller compactor?
1. Compaction under the cement stabilized layer in highway municipal maintenance and replacement projects; compact asphalt concrete at the edges and corners of the trench.
2. During highway construction, when backfilling pipeline culverts, passages, abutments, and other structures, perform compaction operations in areas where large rollers cannot be used.
3. Municipal garden landscape, real estate residential area landscape, sidewalk pavement in golf course construction, sidewalk pavement, and sidewall compaction.
4. Other construction areas are narrow and weight-sensitive compaction equipment can complete compaction work flexibly and efficiently.
Precautions in operation
1. When using a small roller compactor to perform operations, start first, and then start shaking. The speed of the internal combustion engine should be adjusted to medium speed first and then gradually to high speed. It must not be adjusted to high speed at the beginning.
2. In the process of operation, if it is necessary to carry out the operation of speed change and direction change, the machine must be stopped before the operation can be carried out. It is also necessary to pay attention to the need to reduce the speed of the internal combustion engine when shifting.
3. It is strictly forbidden to vibrate the machine on solid ground during the use of the mini roller compactor.
4. If you encounter uphill and downhill road conditions and make sharp turns during the operation, it is strictly forbidden to use the fast gear.
5. In the process of stopping the impact road roller, the first thing to stop should be vibration, and then what needs to be done is to put the reversing mechanism in the middle position, and the transmission needs to be adjusted to the neutral position, and finally, the internal combustion engine is turned off Up.
How to do a good job of starting protection? It has become the focus of everyone’s attention at this stage. The world’s major residential communities, factories, enterprises, government agencies, hospitals, schools, large shopping malls, hotels, supermarkets, airports, stations, etc., actively respond to epidemic prevention measures, formulate special epidemic prevention plans and conduct comprehensive investigations to strictly follow policy standards Site selection for control. In response to regional disinfection, return inspections, personnel protection, employment arrangements, management mechanisms, and other issues, projects in various regions have been carefully deployed to ensure the safety of personnel returning to work.
Some new disinfection methods, and set up corresponding “atomization disinfection channels” and “atomization antibacterial disinfection” at the entrances of major residential communities, factories, enterprises, government agencies, hospitals, schools, shopping malls, hotels, supermarkets, airports, and stations door”. Or the “atomization disinfection cabin” disinfects and sterilizes personnel entering and exiting.
Why choose a smart atomization disinfection door?
Generally, the places where the smart atomization disinfection door is placed are public places with high population density or high flow of people. However, the spread of viruses in public places is more difficult to prevent. However, the traditional disinfection method is not only cumbersome but also time-consuming and laborious. And there is a certain blind zone, it is difficult to achieve the effect of disinfection. The intelligent disinfection door is a kind of equipment that breaks the traditional way, simple to operate, practical, and efficient. It can automatically perform a full range of sterilization and disinfection devices without dead ends based on infrared detection, thereby reducing the spread of viruses. Non-contact disinfection of passing personnel and objects. What is essential is the disinfection equipment.
Using ultraviolet, plasma, lightwave atomization triple disinfection, the disinfection of the control cabinet is more thorough, there are four buttons. When the machine is turned on, the power button will turn on. The lighting button is used to control the lighting. When the disinfection lamp button is turned on, the ultraviolet disinfection on both sides and the plasma disinfection on the top are both turned on. After turning on the disinfection button, the light wave atomization will be turned on, which is divided into low-level and low-level.
The sandblasting machine is a cost-effective casting cleaning equipment with the highest efficiency and less modern investment. The sandblasting machine is generally used to remove rust and rust on the surface of easily corroded materials or workpieces to remove the oxide scale of non-rusty metals. In daily work, the operating procedures of the sandblasting machine are directly related to product safety.
Safety operation rules of the sandblasting machine:
1. The gas tank, pressure gauge, and safety valve of the portable sandblasting machine should be checked regularly. The air storage tank discharges dust every two weeks, and the filter in the sand tank is checked once a month.
2. Check whether the ventilation pipe of the sandblasting machine and the door of the sandblasting machine are sealed. Five minutes before work, ventilation and dust removal equipment must be activated. When the ventilation and dust removal equipment fails, the sandblasting machine is prohibited from working.
3. Before working, you must wear protective equipment and do not operate the sandblasting machine with bare hands.
4. The compressed air valve of the sandblasting machine should be opened slowly, and the air pressure should not exceed 0.8MPa.
5. The blasting particle size should be consistent with the work requirements, and the sand should be kept dry.
6. When the sandblasting machine is working, no unrelated persons are allowed to approach. When cleaning and adjusting operating parts, stop the machine.
7. It is prohibited to use the compressed air of the sandblasting machine to blow dust on the body.
8. After the work is over, the ventilation and dust removal equipment of the sandblaster should continue to run for five minutes and then shut down to discharge indoor dust and keep the site clean.
9. If a person or equipment accident occurs, keep the scene and report to the relevant department.
Oxygen is an important substance for sustaining life activities. Once interrupted, the body will face death. The oxygen content in the air is about 21%. This oxygen level is correct for a normal human body, but for most patients with respiratory diseases, cardiovascular and cerebrovascular diseases, it is far from enough. They often experience symptoms of hypoxia, such as coughing and difficulty breathing. At this time, if oxygen is not supplemented in time and effectively, it may cause irreversible consequences. Therefore, the oxygen concentrator machine has become an important auxiliary treatment method for family oxygen therapy patients and friends, and its effect cannot be underestimated.
So, how to choose an oxygen concentrator machine? All this is exquisite. Assuming that the current oxygen concentration of the molecular sieve oxygen generator is 93% + 3, which is a constant standard in the industry, it can be seen that there are 1L, 2L, 3L, 5L, 8L, 9L oxygen generators on the market with different oxygen flow labels. From this perspective, define the number of users and the performance of different oxygen flow oxygen concentrator machine.
Application range of oxygen generators with different capacities:
Applicable people: sub-healthy people, students, pregnant women, office workers, etc.
Small size, low noise, and low price are the advantages of a 1L small oxygen concentrator, but at the same time, low oxygen flow cannot achieve the therapeutic effect of hypoxic diseases. Non-iatrogenic oxygen supplements suitable for infants and young children, sub-healthy people, students, pregnant women, and other people, can be used for office workers to reduce stress and fatigue. Home oxygen therapy is dedicated to medical care and can improve the symptoms of hypoxia in the body and brain, especially for middle-aged and elderly people.
2L oxygen machine for home
Applicable people: sub-healthy people, students, pregnant women, office workers, etc.
Compared with 1L, 2L oxygen machine for home has a certain oxygen health effect, but it does not belong to the category of medical equipment. They are especially suitable for mental workers and sub-healthy people. A good model can also be used for pregnant women to inhale oxygen.
Applicable people: patients with chronic diseases such as hypertension, hyperlipidemia, bronchitis, etc.
The 3L oxygen generator can meet the medical oxygen standards and can adjust the oxygen flow rate of 1-3L. Individual brands, such as YG medical oxygen generator, can adjust the oxygen flow to 5L, suitable for health care oxygen inhalation for the elderly, and can target high blood pressure and hyperlipidemia. The treatment of obesity, emphysema, pulmonary heart disease, bronchitis, and other chronic diseases is an important adjunct to family oxygen therapy.
5L oxygen generator
Applicable people: emphysema, pulmonary heart disease, moderate to severe COPD, and other severe patients
The 5L oxygen concentrator has a wider application range. In addition to satisfying serious diseases such as emphysema, cor pulmonale, and moderate to advanced COPD, it can also meet the needs of people who have been given oxygen for a long time and can benefit patients who have sudden breathing difficulties.
8L, 9L oxygen generator
Applicable people: It is mainly used for special patients who cannot escape oxygen after long-term oxygen inhalation.
It can be seen that the choice of household oxygen concentrators cannot be hasty, because it is directly related to the safety and health of users. It must be clear whether it is used for oxygen health care or treatment.
Four issues to pay attention to when buying an oxygen generator:
Oxygen health care and oxygen therapy should be treated differently: 1L or 2L oxygen generator is recommended for oxygen health care. If it is used for patients, it is recommended to choose a 3L or 5L molecular sieve oxygen generator, whose oxygen flow and oxygen concentration (93% + 3) are constant.
1. Purchase an oxygen generator with an oxygen concentration of 90% at the maximum flow rate: In this article, the oxygen concentration is divided into a molecular sieve oxygen generator with a constant oxygen concentration of 93% + 3. When purchasing, please be sure to carefully check the oxygen generation method of the oxygen generator. One point to be mentioned here when choosing an oxygen-rich membrane oxygen generator, the oxygen concentration is 90%, 60%, and when the oxygen concentration is 1L, 2L, and 5L 30%. Obviously, the oxygen concentration of the 5L oxygen generator is 30%, which is no different from air and has no healing effect.
3. The oxygen flow rate is adjustable. The oxygen flow of the 3L oxygen generator can be adjusted between 0-3L, and the oxygen flow of the 5L oxygen generator can be adjusted between 0-5L. We can adjust the oxygen concentration by adjusting the oxygen flow rate of the oxygen generator.
4. Molecular sieve oxygen generator is currently the most advanced oxygen generator and the only oxygen generator with international and national standards. The oxygen concentration is constant, always 93% + 3.
