In recent years, Zhisheng Weihua, located in Fengtai District, has been engaged in the research and development of corrosion coating for combustion tail gas and inner wall of chimney flue Anticorrosive coating Based on the on-site corrosion prevention of hundreds of flue gas combustion tail gas and chimney flue, the R&D personnel adopted new technology and combined with high-tech, and developed and produced ZS-1041 Zhisheng Weihua flue gas corrosion prevention coating The R&D of coating has been successfully applied. Zhisheng Weihua smoke anti-corrosion coating Film-forming substance : The coating uses interpenetrating polymer network (IPN) mainly composed of inorganic polymer as film forming material, with good film forming property and high adhesion. Paint pigment The main components are inorganic corrosion resistant materials, nanometer Silicon micropowder, silicon carbide, boron nitride, fine alumina, graphite, ultrafine zinc oxide, titanium oxide, etc. are made into cermet functional fillers to improve the wear resistance and corrosion resistance of the coating. Inorganic fibers are used to enhance the impact resistance of the coating. Appropriate pigments, solvents, additives and wear-resistant reinforcing agent shall be added.
Long term anti-corrosion coating : ZS-1041 Zhisheng Weihua combustion tail gas, flue gas anti-corrosion coating on the inner wall of chimney flue After the polymer of agricultural production system is modified by silicon containing inorganic polymer, the coating can be composed of multi block copolymers arranged alternately, forming a two-dimensional network structure in the coating space, which also forms a point maze form, In addition, the ultra-fine powder rare earth oxide in the coating forms a dense interface transition layer in the coating, which effectively prevents the invasion of acid and alkali solution to the substrate under the joint action. Zhisheng ZS-1041 flue gas anti-corrosion coating of Dongtieying, Fengtai has good corrosion resistance, can simultaneously resist acid and alkali corrosion, and can resist H two S、 Chloride ion, sulfur dioxide, sulfur trioxide, hydrogen chloride, high-temperature water vapor and other media corrosion, to prevent condensate spot corrosion, stress corrosion, chemical corrosion, potential corrosion, alternating corrosion, etc.
Anticorrosive coating has super adhesion and high linear expansion coefficient ZS-1041 Zhisheng Weihua smoke anti-corrosion coating uses the coating film-forming material specially made by Zhisheng Weihua, and inorganic pigments as the filler. The chemical bond - hydroxyl (OH), etc. contained in the coating composition can form a chemical bond with metal ions, and with the help of the coating coupling agent, it can form a covalent chain with metal materials, and the coating has good adhesion with the base material, The adhesion reaches the first level. ZS-1041 Zhisheng Weihua flue gas anti-corrosion coating has strong adhesion with the substrate. The metal oxide nano materials and rare earth oxide ultrafine powders contained in the flue gas anti-corrosion coating composition help the coating form a dense interface transition layer, so that its comprehensive thermodynamic properties match the substrate, The coating also has high flexural resistance and thermal expansion resistance, which can resist the steel combustion tail gas and the inevitable vibration of the chimney in operation despite reinforcement.
Anticorrosive coating High temperature resistance: The base material and filler of Zhisheng Weihua combustion tail gas and chimney smoke inner wall gas anti-corrosion coating are all high temperature resistant inorganic materials. The long-term heat resistance can reach 600 ℃, and the short-term temperature can reach 750 ℃.
Abrasion resistance, smoothness and drag reduction of anti-corrosion coating: The ceramic functional filler composed of various components of Zhisheng Weihua combustion tail gas and chimney smoke inner wall gas anti-corrosion coating makes the coating surface present low surface energy and ultra-low friction coefficient, which can keep the tar and surface in a non wetting state, thus effectively preventing the adhesion of combustion tail gas and viscous foreign matters in the chimney flue. The mutual cooperation of different materials endows the coating with good wear resistance, smooth anti-corrosion performance, and can resist the high-speed impact of smoke and dust and air flow erosion.
Anticorrosive coating has good thermal shock resistance: Zhisheng Weihua combustion tail gas and chimney flue gas inner wall anti-corrosion coating always changes the flue gas temperature, the coating inorganic fiber material plays a very good cross-linking state, and the coating has high thermal shock resistance. When the flue gas temperature changes, the coating does not fall off, and there is no crack.
Long service life of anti-corrosion coating : Zhisheng Weihua combustion tail gas and chimney smoke inner wall gas anti-corrosion coatings are made of material nano materials and treated with inorganic modification in the agricultural production system. The coating has a long service life and good durability. Damaged coatings can be easily repaired, and the environment is pure in the process of preparation, coating and coating formation.
