The road marking machine is also known as the road line marking machine, that is, the lines, arrows, marks, and other signs that we can see on the road every day to traffic information, which play a role in controlling and guiding traffic. The editor will lead you to understand how the road line marking machine works. What should I pay attention to during construction?

The construction personnel of the road line marking machine can be divided into three groups, the road line sweeping defense line group, the paint melting and mixing group, and the marking coating group. The construction temperature of the road line marking machine is generally 100℃ to 300℃. If the ambient temperature is lower than 100℃, the construction cannot be done, and the road line must be dry and dust-free during the construction process.

• 

• 

How should the road marking machine be constructed, and what aspects should be paid attention to?

1. Pavement sweeping and laying line group: first use a hand-push pavement sweeper to clean the road surface soil, floating dust and obstacles, dust, asphalt, oil, or other harmful substances, and mark the wires as required.

2. Paint melting and stirring group: Put the paint (auxiliary) into the hot melt kettle, and control the temperature in the kettle between 180 ℃ and 210 ℃, while melting and stirring, strictly control the temperature. After melting and dispersing, in order to ensure better marking quality, carry out inspection and testing. The inspection method is to take a small sample of the paint in the kettle, apply it to a sheet (about 1.6mm thick), let it cool naturally, and bend it with your fingers after drying. The smear breaks when it is bent to about 35 degrees.

3. Marking coating group: When the paint after the hot melt kettle is melted into the marking tank, it needs to be filtered with an iron screen. Ignite the fire under the barrel and at the side of the scribe to maintain a proper construction temperature. Then pour the glass beads into the box, and the construction can begin. When marking the line, the marking machine coats the wire according to the wire, and the suitable temperature of the coating during coating is about 180°C.

• 

• 

What should the road marking machine pay attention to?

1. At the same time, the marking line should be spread evenly and widely with glass beads. The amount of glass beads is 0.3~0.4Kg/m, and the spreading time should be strictly controlled according to the temperature of the coating.

2. All horizontal markings, legends, symbols, and arrows should be uniformly coated with the template, the surface should be flat, and the wet film thickness should meet the requirements of the drawing.

3. In order to improve the adhesion between the road surface and the coating film, the aluminum alloy solid solution thermal aging furnace must be coated with primer and then marked with a marking machine on the road surface. The primer is composed of synthetic resin, plasticizer, and aromatic solvent. Before the primer is dry, paint line drawing is not allowed.

4. Carefully check the construction equipment before the road marking machine construction to ensure that it is normal.

The shot blasting machine is a kind of machinery-related machine, which is generally used to process the surface of the workpiece. Similar to it, there are the Sandblasting machine and the floor shot blaster. Here is the main difference between the shot blasting machine and the sandblasting machine.

There are many types of shot blasting equipment, such as through-type shot blasting machine, suspended shot blasting machine, crawler shot blasting machine, drum shot blasting machine, rotary table shot blasting machine, wire shot blasting machine, etc., shot blasting machine The principle of shot blasting is to make the motor start the impeller to make it rotate, and then the pellets are thrown to the workpiece, relying on the action of centrifugal force, through continuous collision and polishing, the workpiece is more beautiful and the life of the workpiece is improved.

Sandblasting Equipment

The sandblasting of the automatic sandblasting machine is a form of using air compression to quickly blow out the quartz sand to remove the surface of the part. It is also called sand blowing in the processing plant, which not only removes rust, but also removes oil, which is very effective for the coating process. The sandblasting machine is suitable for anti-rust treatment on the surface of the component; for the surface decoration of the component, in the steel frame structure, the use of high-strength bolts to carry out the connection is an excellent form, because the high-strength connection uses the sliding friction in the middle of the fusion surface to transmit force, Therefore, the quality of the fusion surface is very high. At this time, sandblasting must be used to solve the fusion surface. Sandblasting is divided into the dry sandblasting machine and wet sandblasting machines.

Both shot blasting and sand blasting machine can clean and decontaminate the workpiece. The purpose is to prepare for the next sequence, that is, to ensure the roughness requirements of the next process, and some are to achieve surface consistency. There is a strengthening effect, and the sand blasting machine is not obvious. Generally, shot blasting is small steel balls, and sand blasting is quartz sand. According to different requirements, the number of sub-items. Sandblasting and shot blasting are used in precision casting almost every day.

Hydraulic rock splitting machine is a kind of equipment that uses common physical tip splitting principle and hydraulic transmission principle to transform axial hydraulic thrust into lateral splitting force. The rock splitting machine is a safe, efficient, easy-to-operate and low-cost secondary disassembly equipment.

Advantages of rock splitting machine:

1. Safety: The hydraulic rock splitting machine applies the physical characteristics of hydraulic oil, which is non-compressible and movable, and adds static thrust to complete the task of static controllability. Therefore, there is no need to take complex safety measures, and there will be no hidden risks like blasting and other impact demolition and rock drilling equipment.

2. Environmental protection: Green environmental protection demolition expert-rock splitting equipment When starting the construction task, there will be no vibration, impact, noise, dust flying, etc., and the surrounding environment will not be affected. Even in densely populated places or indoors, in urban construction, and close to tight equipment, construction tasks can be carried out without interference.

How to use hydraulic rock splitter:

1. Use a rock drill to drill a hole in the rock. The diameter of the hole depends on the outer diameter of the hydraulic rock splitter wedge component, and the size of the wedge component depends on the size of the rock at the construction site. The volume of the rock is large, so choose a large diameter. The wedge component can also be small in diameter and porous, and the volume of the rock is small. Small diameter wedge components are used. The drilling depth is generally 500mm. When drilling, pay attention to the orientation of the ore drilling hole should be perpendicular to the surface where the hole is located, the size of the hole should be consistent with the diameter of the rock splitting equipment, and the depth of the hole should be 200-250mm deeper than the insertion length of the wedge component.

2. Insert the splitter into the manhole, and adjust the splitting direction appropriately according to requirements.

3. Start the pump station.

4. Control the reversing valve to extend the piston and start splitting. After the rock cracks a small fine line, the reversing valve reverses, the piston rod and the inner wedge retract, and the splitter is rotated to make it and Turn the direction of the initial crack at an angle, and then stop splitting again, so that one rock can be broken into multiple small rocks.
