ZS-1032 Strong oxidation resistance coating PTFE is used ethylene , barite, flake graphene and other materials passivated and chelated at high temperature. After curing, ZS-1032 strong oxidation resistant coating has high inertia and temperature resistance up to 250 ℃.
Film forming solution and inorganic in coatings filler After mixed curing, polytetrafluoroethylene is more stable, not easy to lose electrons, and has good swelling resistance. Barite, graphene and other materials have good chemical stability and high hardness in the coating. Smaller particle size can also make the film forming solution form a denser film. The coating is highly dense, the material molecules are not easy to lose electrons, and the coating has good acid swelling resistance.
ZS-1032 strong oxidation resistant coating can withstand the oxidation corrosion of strong oxidizing materials such as concentrated acid solutions (salt, sulfur, nitrate), strong intermediates, polar solvents for a long time, as well as the penetration corrosion of aviation kerosene and other oils. It is difficult for ordinary anti-corrosion materials to prevent oxidation corrosion of concentrated nitric acid. When ZS-1032 strong oxidation resistant coating is resistant to strong oxidation corrosion Very low swelling rate In addition, due to the high density of the coating, it is difficult for the molecules of inert materials in the coating to lose electrons, which ensures that the coating can resist the oxidation corrosion of concentrated nitric acid.
The film thickness only needs 300-500 μ m to achieve the protection effect and protection period of conventional anti-corrosion coatings. The interval between passes shall not exceed 2h. The design film thickness can be achieved by using airless spraying for about 4 passes, saving time and labor. The coating can be brushed, roller coated, airless spraying, with high solid content, good thick coating performance, and no need to use lining cloth, etc Auxiliary materials The construction is simple and the construction period is short. When the coating has defects or defects in later application, only local brushing repair is needed, which greatly reduces the maintenance cost and shortens the maintenance period.
Applicable working conditions Medium environment: concentrated hydrochloric acid, concentrated sulfur H2SO4 acid, concentrated nitric acid, sodium hypochlorite water, hydrogen peroxide, chromic acid, ozone water, glacial acetic acid, silicon tetrachloride, potassium permanganate, intermediates, active agents, accelerator , kerosene, diesel, diluent and other corrosive media.
