coating
coating temperature-resistant performance is good, with the base material matching the temperature-line expansion coefficient, not due to internal stress or thermal stress and damage to the coating. Can withstand vibrations and shocks during equipment operation. The coating has a long service life and good durability, and the damaged coating can be easily repaired. Suitable for petroleum, chemical, fertilizer industry reaction tanks, condensation equipment, production pipelines and metallurgy, mining, sewage treatment equipment, light industry and other enterprise equipment of normal temperature and heavy corrosion protection. ZS-722 acid-base-resistant thermal conductive anti-corrosion coating, is Beijing Zhisheng Weihua Chemical Co., Ltd. independently developed on the basis of high-temperature heat conduction, infrared radiation coating, including high temperature, acid-base and high thermal conductivity paint. ZS-722 acid-base thermally conductive antiseptic coatings are suitable for metal, concrete, stone, ceramic, glass and other substring materials.
acid-alkali anti-corrosion coating ZS-722 thermal anti-corrosion coating temperature resistance is good, by different types of polymers, through the interoperability network technology composed of inorganic-organic polymers, mutual coordination, so that the coating's temperature resistance performance is the best. The coating is flat, saturated and ceramic. Excellent resistance to boiling water.
1, substation treatment: before coating operation, should remove the surface of the substation oil, rust, oxidation and so on. It is recommended to use a moderately alkaline water-like cleaning agent to remove oil and then wash it with clean water. All steel surfaces to be coated must meet Sa2.5 requirements. When the coating is partially repaired, the steel surface must be polished to St3 level. Surface roughness requires control in the range of 25 to 40 m.
2, ZS-722 thermal anti-corrosion paint brush money mixing, matching ratio: main agent: curing agent : 9:1 (weight ratio) mixing, should be constantly stirred liquid ingredients, slowly poured into the solid parts. Otherwise, it is easy to lump, we highly recommend the use of mechanical stirring. After mixing, the mixed paint is filtered with a 40 mesh screen and poured into another container. It is required to stir continuously and slowly so that the coating is always in a suspended state after mixing the paint valid for 8 hours, please schedule the use according to the construction schedule.
3, ZS-722 thermal anti-corrosion coating environmental conditions, spraying operations should be carried out as soon as possible after the substation treatment, generally should not exceed 8 hours. The surface temperature of the substation and the ambient temperature are generally not less than 10 degrees C, the surface temperature should be at least 3 degrees C above the dew point, and the relative humidity of the air should not exceed 85%.
