APPLICATION FIELD

The principle of the road marking removal high-pressure jetting machine is to continuously input the ultra-high pressure water flow generated by the high-pressure cleaning machine into the hand-push cleaning machine through a high-pressure hose, and then spray it on the road surface at high speed. The water pressure can reach 1500bar. Wherever the hand-push cleaning machine is pushed, the road surface will be intact after the rotation and flushing of the high-pressure water flow, and the road markings will be cleaned by the road marking remover.

In recent years, ultra-high pressure cleaning machines have gradually developed, and ultra-high pressure water jet technology is currently a very effective road marking removal process. Commonly used traditional road marking removal methods are divided into manual cleaning, chemical cleaning and mechanical cleaning. Although these traditional road marking removal methods can remove the markings cleanly, they will damage the road surface, affect the road landscape, and increase the cost of road maintenance. Therefore, it is very important to choose the appropriate road marking removal method according to the degree of impact on traffic, the required operation time and the degree of impact on the environment.

Water Blasting (Hydro Jetting) Road Marking / Pavement Cleaning machine

Using hydro blasting to remove the road markings can be quick, easy, and efficient, Whether the road markings are red, white, yellow, or more, Using a top of the range electronically controlled water jetting system can remove the markings through propelling itself back wards and forwards with ultra high pressure water.

High way markings introduced water blasting as a road marking removal technique. lt is now the preferred road marking removal technique by authorities.

Water blasting quickly removes markings faster and more thoroughly than abrasive methods. This method will not damage the pavement or asphalt of the road . Water blasting -hydro blasting is fast and productive, and avoids exposing the environment to chemicals or contaminants. lt also simplifies clean up, is dustless and leaves a clean surface.

Ultra-high pressure cleaning machines have become the leading equipment for industrial cleaning in the world. Ultra-hydro blasting machines use the impact force, shear force and other factors of ultra-high pressure water jets to act on the surface of the markings, destroying the structure and state of the markings, thereby achieving the effect of clearing the marking layer. The key technologies for water jet marking removal are the development of ultra-high pressure pump units and the analysis of the marking removal mechanism and influencing factors. In the operation of clearing traffic signs, different water jet pressures, moving speeds, etc. should be used according to the actual thickness of the markings, so as to achieve better cleaning efficiency and effect.

The cleaning effect should not only refer to the cleaning quality, but also consider the cleaning efficiency. The cleaning effect of road marking lines mainly depends on four aspects: jet pressure, actuator movement speed, target distance, and rotary joint speed. Only by mastering the factors that affect ultra-high pressure water cleaning equipment can we achieve twice the result with half the effort in actual use, and truly make ultra-high pressure cleaning machines give full play to their advantages of wide cleaning range, low cost, high efficiency, good quality, water saving and environmental protection in industrial cleaning.
