Over the years, Zhisheng Weihua Chemical Co., Ltd. has accumulated rich experience in the actual conditions of graphite and surface porous materials to ease reaction in high temperature environment yes Anti oxidation experience of graphite and surface porous materials past High temperature soothing reaction coating The lack of oxidation prevention in graphite and surface porous materials has led to the introduction of a high-temperature coating for graphite or surface porous materials to prevent oxidation, ZS-1021 graphite high-temperature soothing reaction coating, This The coating is acidified and synthesized under high temperature and pressure, and its temperature resistance can reach 2600 ℃. The coating has good curing effect and dense coating. It has both physical adhesion and chemical bridging with graphite and porous materials, and forms an integrated structure with the substrate. The coating has good adhesion, smooth, plump and dense coating, good self-cleaning adhesion resistance, thermal shock resistance and creep resistance, and good self-healing and repair ability for thermal expansion and cold contraction, It is resistant to corrosion and penetration of molten slag and high-temperature sundries, with an oxygen diffusion resistance of more than 96%, and has a long service life of anti oxidation under high temperature.
ZS-1021 graphite soothing reaction coating developed by Zhisheng Weihua adopts self crosslinking film-forming solution, which contains relatively groups, such as polyacid group, with high temperature resistance; The carboxyl (- COO -) internal crosslinking adjusts the zui well; Amine (- NH3) film-forming network cross-linking makes the coating dense, and these functional groups play a synergistic effect. In this way, ZS-1021 graphite soothing reaction coating solution has high temperature resistance, which can reach 2600 ℃, high adhesive strength and good adhesion. filler The double-layer continuous cube structure Er-Y-Ls rare earth is selected as the material, which has the advantages of high temperature resistance, resistance to oxygen diffusion rate of more than 96%, good soothing reaction performance, acid and alkali resistance, good self-healing and repair ability, resistance to slag and high-temperature debris erosion and penetration erosion.

Performance characteristics of ZS-1021 graphite soothing reaction coating:
The coating can be directly applied on various wet or dry base surfaces. The construction is simple, single component, and can be directly applied after mixing evenly , Strong adhesion with the base surface, high molecular substances in the coating film can penetrate into the micro cracks of the base surface, with high density and good waterproof performance. The coating film has good flexibility, strong adaptability to the expansion or cracking of the base course, high tensile strength, good thermal expansion and cold contraction, good thermal shock resistance frequency, and can be used in high and low temperature conditions for a long time. coating by Pure water-based paint, no volatile matter, green, harmless, tasteless, pure environment, no harm to human body. coating by The modified coating of inorganic agricultural production system has good weather resistance, no flowing at high temperature, no cracking at low temperature, good aging relieving performance and oil corrosion resistance. The coating is thin, and the Zhisheng Weihua sealing coating is smooth and full, with good self-cleaning performance. It is a highly decorative waterproof coating. The paint has strong permeability and good exhaust performance, which can well exclude the air inside graphite and porous materials, and can also well block the entry of external corrosive media to prevent material oxidation.
