Sandblasting method

This will remove old coatings, rust and other debris and produce a clean, rough surface The most likely methods are dry blast cleaning, mortar blast cleaning (adding water), and wet blast cleaning (adding water and other abrasives) Huicong coating network news: in order to ensure the best adhesion between the substrate and the coating, the surface of the substrate needs to have a certain roughness From this point of view, blast cleaning is the best surface treatment This will remove old coatings, rust and other debris and produce a clean, rough surface The most likely methods are dry blast cleaning, mortar blast cleaning (adding water), and wet blast cleaning (adding water and other abrasives) Dry blast cleaning can produce clean and dry surfaces and required roughness, but it will produce a lot of dust that will directly pollute the environment; mortar spray cleaning and wet blast cleaning can get a proper roughness and clean substrate surface, without dust, but the deficiency will produce flash rust However, it is also found that after the blast cleaning, there will be a lot of abrasive debris left on the surface of the substrate, especially on some alloy substrates, which may form point corrosion at the debris For stainless steel, aluminum and galvanized parts, the use of non-metallic abrasive substrate surface treatment is very important.
