IPN8710 drinking anti-corrosion steel primer: from polyurethane, polyethylene, modified epoxy resin, non-toxic anti-rust pigments, additives and other components, room temperature curing form an interpenetrating network, a dense film structure, acid and alkali, salt, Excellent rust resistance, strong adhesion. IPN8710 drinking anti-corrosion steel finish: epoxy, rubber resin-modified, non-toxic anti-rust pigments, additives and other components. Excellent chemical resistance, non-toxic, anti-microbial erosion. Purpose: IPN8710 primer coat for water supply for the water supply pipeline wall IPN8710 corrosion finish. This is for the drinking water pipeline corrosion engineering, non-polluting, non-toxic, which major issues related to the health of the masses as a preservative workshop department of our company, it is important to keep in mind during the manufacturing process to cut corners, shoddy , real ones, always thinking about the lives of the people! Pipe buried into the soil, and the soil is a very complex system of gas, liquid and solid phases are formed. Many factors affect soil erosion, for sewer pipe, the main factors: (1) Moisture: Water the soil to become the electrolyte, is caused by electrochemical corrosion prerequisites. Although in the design of the pipe below the water table, but groundwater influenced by seasonal rainy season, the water level changes in the magnitude of 0.5 ~ 1.0m, groundwater close to the surface during the rainy season. Changes in soil moisture, especially in corrosive alternating wet and dry soil. (2) Temperature: soil temperature through physical and chemical properties of soil to the corrosive effect of soil. Jiaxing winter low temperature, specific resistance, corrosion light, summer soil temperature increases, the resistance is low, not only to accelerate steel corrosion, and temperature increased microbial activity, but also promote the corrosion of the steel pipe. (3) Stray current: in Jiaxing soil inevitably exist stray current.
