3, high-pressure water jet removal method
With the enhancement of awareness of environmental protection, marking removal of environmental protection requirements are also higher and higher, so the high-pressure water jet marking removal method came into being in recent years, the more favored a marking removal method, the main construction machinery for the high-pressure water jet marking cleaning machine. Clear machine using pressurized system to make water from the nozzle shot, this water jet has a very strong impact and cutting force, can directly penetrate into the asphalt pores in the marking paint to remove. The cleaned road surface not only does not have any marking paint residue, but also does not have any damage, the whole road surface will become very clean. Ordinary high-pressure water jet removal machine in the cleaning process will produce a lot of waste water, the water may cause the road surface is not hygienic, or penetrate into the asphalt pore damage to the road surface, so in the cleaning process should be equipped with the appropriate cleaning equipment.
The automatic separation system of our HR-1400 high pressure water let road marking remover machine can draw residual water and waste water into the vacuum chamber, in addition to separating the residue from the waste water. The residue can be automatically put into plastic woven bags and the waste water will flow into the waste pool. When the waste pool is full, the waste water will be discharged into the sewer through the water pipe. Very convenient, safe and environmentally friendly.
