Shandong manufacturer directly sells glass flake mastic desulfurization tower inner lining anti-corrosion mastic sludge sewage tank anti-corrosion materials

  Our factory has summarized the advantages and disadvantages of traditional glass flakes
After years of practice and exploration, we have produced high-temperature, high acid resistance and high adhesion glass flake mastic, which has completely solved the above problems
According to the experience and lessons of several imported and domestic glass flake mastics in the anti-corrosion of mastic in acid resistant bricks in China, our factory adopts modified phenolic epoxy vinyl ester resin, with glass flakes as the main filler, barite as the modifier, adding anti sedimentation agent Using cobalt salt initiator, polymerization inhibitor and curing agent as raw materials, acid resistant glass flake mastic for acid resistant brick and acid resistant glass flake mastic for steel cylinder were produced
Compared with the traditional acid resistant glass flake mastic, it has the advantages of fine material, easy construction, easy filling of corrosive parts, high hardness, fast hardening speed, strong adhesion with acid resistant bricks and steel cylinders, high hardness, not easy to scratch, good corrosion resistance, high temperature resistance of 200 ℃, no cracking and foaming, and short construction cycle
Through special proportioning, 10mm--20mm thick anti-corrosion coating can be achieved on the inner wall of flue and chimney
The hardness of this anti-corrosion coating can reach Mohs 7, and the service life can reach more than 20 years
It has been used in the flue and chimney of the thermal power branch of Ningxia Juxi vinyl chloride Co
, Ltd
, in the flue and chimney of Jinzhou Datang International Thermal Power Co
, Ltd
, and at the junction of the flue sulfur absorption tower of Shaanxi Datang Huxian No
2 power plant The company's leading products: Epoxy Mastic, vinyl glass flake mastic, anti-corrosion coating, glass flake, which are widely used in the corrosion prevention of inner wall of chimney, chemical pool and pipeline
The company always takes “ Quality for survival, reputation for development ” For the purpose of the enterprise, be honest, trustworthy, and strive for excellence in production and construction Long term corrosion protection: good corrosion resistance, resistance to humid atmosphere, acid rain, seawater, SO2, SO3, H2S and other corrosive media, and high stability to petrochemical products and organic solvents
Product Description: in order to meet the requirements of environmental protection, the wet contact acid gas to sulfuric acid (WSA) technology is used to solve the problems caused by acid gas
The process also has the characteristics of strong medium corrosivity, high temperature of treated flue gas, high solid content of SO2 absorption liquid, strong abrasion resistance, large equipment Anti-corrosion area, high construction technology quality requirements, and difficult maintenance after anti-corrosion failure
At present, the commonly used flue anti-corrosion materials include acid resistant brick acid resistant mastic, steel titanium composite structure, steel stainless steel composite structure, etc
, but they all have the disadvantages of large air leakage coefficient, loose sealing and high cost
Therefore, the development and use of a coating that can be used for a long time in the corrosive environment under the dew point of sulfuric acid is of great significance to solve the corrosion of sulfuric acid plant, improve its service life and reduce energy consumption
Vinyl resin glass flake mastic is a thermosetting polymer, which combines the excellent corrosion resistance and mechanical properties of epoxy resin, and has the process performance of rapid curing of unsaturated polyester resin
Vinyl ester resin is a kind of unsaturated resin with vinyl ester groups at both ends of the molecule and epoxy resin as the intermediate skeleton
At present, it has been widely used in the anti-corrosion fields of chemical industry, metallurgy, construction and other national economic departments
In this study, aiming at the corrosive environment in the wet desulfurization unit, phenolic epoxy vinyl ester resin was used as the main film-forming material to optimize the ratio of heat-resistant filler and glass flake, so that the coating had excellent mechanical properties and good corrosion resistance at 180 ℃, and the corrosion resistance of the coating in sulfuric acid solutions at different temperatures and concentrations was discussed to determine the heat-resistant temperature of the coating in sulfuric acid solutions of different concentrations, It provides a basis for practical application
