The advantages and disadvantages of acid-base-resistant thermal anti-corrosion coatings

China Coatings Online News Information:
coating must meet the acid- and alkali-resistant requirements of the working environment, acid-base-resistant thermal anti-corrosion coating temperature change resistance is good, with a temperature-line expansion coefficient matching the base material, 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.acid-base thermal conductive anti-corrosion coatings are suitable for oil, 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 high temperature heavy anti-corrosion protection. Acid-alkali-resistant thermal and anti-corrosion coatings are suitable for metal, concrete, stone, ceramics, glass and other substring materials.acid-base-resistant thermal antiseptics apply good temperature resistance, by different types of polymers, through inter-transmission 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.to ensure coating quality, please read the instructions for use and the coating specifications for the product carefully.: Before applying , oil, rust, oxidation, etc. should be removed from the surface of the substation. 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 level 2.5 requirements. When the coating is partially repaired, the steel surface must be polished to level 3. Surface roughness requires control in the range of 25 to 40 m.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.conditions:should be carried out as soon as possible after 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%.
