    Environmental protection is always the theme of healthy deve

    There are no Millennium paintings on the green mountains and stringless Guqin in the green water. Green mountains and green water, improve the ecological balance. Environmental protection is always the theme of healthy development of enterprises. In the past, tanks in chemical plants were renovated by dry blasting technology. The dust pollution of dry blasting is serious, and sand blasting operators are in close contact with dust. Although some protective equipment is worn, the protective effect is not ideal. It's very harmful. The environmental protection department also conducts regular inspections. In some construction sites, sand blasting is not carried out in the daytime, but construction is carried out at night. The construction photos at night are not good. Sand blasting operators working in dusty environment are prone to safety accidents and affect the quality of sand blasting. It's big, too. The following is a photo of dry sandblasting showing dust contamination from dry blasting. What kind of surface treatment technology is best used in the process of paint removal and rust removal in chemical tank sand blasting anti-corrosion engineering of chemical plant? After practice, the water sandblasting technology was selected. According to more than 1100 new red gun sandblasting end users, the main customer websites of dry sandblasting users were visited, and the sandblasting speed and sand blasting cost of customers were summarized. According to environmental protection requirements and field experience, the first generation was put into operation in 2015 and contracted by foreign petrochemical enterprises. The second generation, the third generation and the fourth generation have been launched successively. At present, there are at least 400000 square meters of chemical plant warehouse. Tank. The practical application of water cannon in oil tank (the application of four major oil products in China) has summarized a lot of water cannon experience. In terms of the current use, users can accept the use, which means that the water blasting technology is feasible and market recognized. Let's look at the photos and videos of a chemical plant's water sandblasting process: after actual use, water sandblasting is more effective than dry sandblasting, with surface cleanliness of Sa2.5 and sa3.0, and surface roughness of rz35-75 μ m (the higher the particle size and hardness of sandblasting abrasive, the higher the hardness, the higher the surface roughness). The remote control is labor-saving, more convenient and less water consumption. It is suitable for removing paint and rust of storage tank in chemical plant. Water blasting technology improves the blasting environment, no dust pollution, and meets the requirements of environmental protection.
