Different specifications, price is not the same. Plug Grating relative density of sulfuric acid detergent manufacturers use steel grating 1.84 ratio 24:22 Lanzhou trench cover grille, 10 lithium chloride, hydrochloric acid ratio of 1.15 relative density 25:35, 5 water with ammonium chloride 41:38 ratio trench cover grill manufacturers, each component can be dissolved in water. Cleaning plug steel grating, steel, black oxide film and surface rust. Cleaning the grill temperature Yulin trench cover at 20 ~ 80 ℃, remove the rust black oxide film at a temperature 60 ~ 80 ℃ time is about 1 ~ 2min, can effectively replace concentrated hydrochloric acid. Advantages 1) washing oxide film speed and appearance of the same cleaning effect and hydrochloric acid; 2) Price ratio hydrochloride, and the washing increased; 3) harmful hydrogen chloride gases reduce evaporation, significantly improved environmental pollution, extend equipment life.
