Hot to Clearn The HotMelt Thermoplastic Road Marking Paint Line
1. Knife and axe. If the marking area is small, a kitchen knife can be used to cut the marking. After the hot-melt marking is solidified, it is relatively strong, and it can fall into lumps when cut with a knife. The disadvantage is slow efficiency. The marking can be removed cleanly.
2. Marking removal machine is actually a small milling machine, which mechanizes knives and axes. The efficiency is improved but the effect is not good. Can not effectively distinguish the thickness of the marking. Many places are not cleaned or cleaned too deep to damage the roadbed.
3. Thread remover. I heard that there is such a chemical agent, but I haven't actually seen it. At the same time, I heard that the effect is not very good.
4. Shot blasting machine. The rice-sized steel balls are constantly hitting the ground, turning the hot-melt markings into powder and being sucked away by the vacuum cleaner. Will not cause too much impact on the roadbed. Clean up is relatively clean. It is a kind of high-efficiency line-removing equipment that costs about 100,000 yuan.
5. The fifth method is actually to combine the second and the fourth. It is currently the most cost-saving method for removing markings. Just lightly mill the markings with a small milling machine. Remove more than 60% of the protruding part markings. Then use a shot blasting machine with a cleaning width of 270mm to clean the milled markings twice. Because more than 600% of the hot melt markings have been cleaned up in the early stage, light shot blasting can perfectly remove all markings. The cleaning efficiency is a little slower for a person to walk normally. The cleaning effect is very good. shortcoming. The equipment cost is high.
