ZS-1041 Zhisheng Weihua Flue Gas Anticorrosive coating Film-forming substance : Interpenetrating network polymer based on inorganic polymer is used as film-forming material, and silicon containing inorganic polymer in solution is used as main chain to graft polymer modified resin of agricultural production system at high temperature to obtain multi block graft inorganic agricultural production system chelating polymer composed of alternating arrangement. coating The main components of solid pigments are inorganic corrosion resistant and wear-resistant materials, such as nanometer Microsilica , silicon carbide, boron nitride, fine grain alumina, graphite, ultrafine zinc oxide, titanium oxide, ceramic beads, micro powder zirconia, etc., which are made into wear-resistant ceramic functional fillers under high temperature sealing, improve the hardness, high wear resistance, corrosion resistance, high temperature resistance, impact resistance and good ductility of the coating. The coating also uses inorganic ceramic fiber to increase the internal cross strength of the coating and enhance the impact resistance of the coating. The paint is also matched with appropriate pigments, solvents, additives and added with wear-resistant enhancer.
The advantages of ZS-1041 flue gas anti-corrosion coating are mainly reflected in:
Surface drying time: ZS-1041 flue gas anti-corrosion coating only needs 300-500 μ m film thickness to achieve the protection effect and protection cycle of conventional anti-corrosion coating, the interval between passes shall not exceed 2h, and the design film thickness can be achieved by using airless spraying for about 4 passes, saving time and effort.
Water absorption rate after 24h immersion: the functional anti-corrosion pigments and fillers in ZS-1041 flue gas anti-corrosion coating are all nano scale powder reprocessed at high temperature. The smaller particle size makes it easier for individual scales to be stably dispersed in the coating system, and at the same time, there will be no overlapping hollowing, and the permeability is better, This is one of the main reasons why ZS-1041 flue gas anti-corrosion coating can achieve the anti-corrosion effect of several mm thick conventional anti-corrosion coating only 300 μ m.
Heat resistance: ZS-1041 flue gas anti-corrosion coating has a temperature resistance range of 750 ℃, and can be used normally at 600 ℃ for a long time. This performance makes the anti-corrosion of high-temperature equipment more reliable and reduces the damage of anti-corrosion coating caused by special conditions.
Fire resistance: ZS-1041 smoke anti-corrosion coating is incombustible and fireproof; During construction, if the back of the metal substrate is welded, the front coating with an area of about 1cm extension will become brittle. It needs to be polished locally and repainted.
Corrosion resistance: ZS-1041 flue gas anti-corrosion coating can withstand long-term acid immersion, alkali immersion and NaCl solution immersion, and has integrated impermeability and corrosion resistance, which can target various possible corrosion of equipment.
Conductivity: the coating contains graphite flakes, conducting static electricity and preventing ash deposition.
Temperature change resistance: linear expansion coefficient of ZS-1041 flue gas anti-corrosion coating is 16-23 × 10 -6 /℃, which is in the same order of magnitude as the linear expansion coefficient of the metal substrate of the equipment, and the difference between the two is not significant. Because the coating is thin, the heat conduction speed is fast, and it can quickly reach a temperature balance with the substrate. When encountering rapid cooling and heating conditions, the deformation is almost consistent with the substrate, and it is not easy to produce temperature difference stress to cause damage to the paint film. Good thermal shock resistance.
Abrasion resistance: ZS-1041 flue gas anti-corrosion coating has smooth surface and small friction coefficient. On the premise of meeting the requirements of the standard, more stringent sand falling abrasion test (SY/T0315-97) was added. The test results show that the product has good abrasion resistance and impact resistance. In addition, when used together with ZS-1042, the wear resistance can be increased by more than twice.
Aging resistance: ZS-1041 flue gas anti-corrosion coating uses inorganic agricultural production system high temperature chelating resin. The agricultural production system has a low content of ingredients, so the coating is inorganic inert after film forming, with good aging resistance. The measured index was originally higher than the 500h specified in the standard.
Applicability: the coating can be applied by brush, roller or airless spraying, with high solid content, good thick coating performance, no need to use auxiliary materials and processes such as interlining cloth, simple construction and short duration. 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.
