Difference between marking cleaning brush cleaning method and natural gas combustion method

Abstract: the working principle of the marking cleaning brush cleaning machine is to drive the steel wire brush disk through the power and transmission device to remove the attachments on the working surface. According to the different devices and working principles, it can be divided into heating type, thixotropic type and round-trip type.

The working principle of the heating brush cleaning machine is to drive the steel wire brush disk through the power and transmission device to remove the attachments on the working surface. According to the different devices and working principles, it can be divided into heating type, thixotropic type and round-trip type.

Heating brush cleaning: heat the original marking before removing the marking, and then remove it with a steel wire brush disc after the marking is softened; Thixotropic brush cleaning is to brush a layer of chemical thixotropic paint remover on the marking surface before cleaning, so that it can have full contact with the marking paint, swelling, peeling, softening, separation, falling off and other physical and chemical changes, and then use the steel wire brush disk to clean the marking; The reciprocating brush cleaning is to make the steel wire brush disk move back and forth on the working surface driven by the power device by adjusting the pressure of the spring acting on the steel wire brush disk, so as to remove the marking paint or dirt in the gaps at different depths on the road surface.

The brush cleaning method can completely remove the marking paint, but it needs to heat or swell the marking or needs to move back and forth, resulting in a slow removal speed. Therefore, it is not suitable to be used when the road traffic is busy. At the same time, it should not be used when there are residents around to rest because of the certain noise during construction.

Marking removal natural gas combustion method

Natural gas burning removal marking is to use natural gas fire gun to aim at the marking to burn it. The construction process is simple, the required equipment is simple, and there are basically no professional requirements for construction personnel. However, because the markings attached to the road surface are not easy to burn, the construction speed is very slow, and not all markings can be well removed. Generally, the removal effect is good for thick hot-melt markings. In addition, the burning of markings will produce a large number of harmful gases, which is unfavorable to the construction personnel and the environment. Marking removal soda jet cleaning soda jet cleaning is to remove the marking through the soda jet cleaning machine. The soda jet cleaning machine uses a high-pressure pump to fracture a solvent that can dissolve the marking paint (such as water-soluble sodium bicarbonate) to release energy, so as to remove the marking paint or other pollutants. At the same time, the solvent that dissolves the marking paint will then be cleaned. Soda spray is a very inexpensive and effective method of removal that doesnot cause any damage to the work surface area.

However, the dissolution of marking paint requires a certain reaction time, so the removal efficiency of soda spray is relatively low, which is not suitable for long-distance marking removal, and is not effective for all marking. Generally, it has a good removal effect for hot-melt marking paint. In addition, the soda jet cleaning method requires professional equipment and multiple operators. In foreign countries, it is usually completed by special institutions.
