How to choose epoxy vinyl resin metallurgical anticorrosion?

Dec. 04, 2019

In the metallurgical industry, due to the complex situation of the corrosive medium in the production process, the objects of application include process pipelines, production equipment, and buildings and structures. The selection of epoxy vinyl resin anticorrosive applications must fully consider the objective requirements of the production process, such as the strength of the medium , Concentration, temperature, working state is dynamic or static, indoor and outdoor, pressure-resistant and other factors and their changes. The first is to grasp the characteristics of the environment, and the second is to optimize the structural design. There are many types of non-metallic corrosion-resistant materials suitable for the highly corrosive chemical media environment of the metallurgical industry. Epoxy vinyl resins are relatively successful and effective materials. Epoxy vinyl resin materials can be cured at room temperature and used in corrosion-resistant floors. It has good adjustability. As a highly corrosion-resistant new material, vinyl ester resin is used in defogger and electrolytic cell materials. The main features are: curing at room temperature, easy operation and good adjustability.

Chemical resistance vinyl resin is used as a highly corrosion-resistant new material for defoggers and electrolytic cell materials. The main varieties are: CH-2, CH-5, both of which have methacrylic epoxy structure; T-158, which has methacrylic acid Phenolic epoxy structure. Among them: CH-2 resin has excellent comprehensive properties, high corrosion resistance, and alkali resistance is more prominent; CH-5 resin has good toughness, leakage resistance and sealing performance, and the use temperature can reach 100 ° C; T-158 resin has higher resistance The temperature is 120 in wet state and 150 in dry state; T-158 resin has excellent corrosion resistance, resistance to some solvents and oxidizing media. It has the following characteristics: making anticorrosive monolithic resin flooring with light weight, high strength, seamless, and low shrinkage; used for anticorrosive block building flooring, masonry of equipment linings, hook (irrigation) joint mortar, and cement adhesion Material receiving; acid, alkali, salt and partially oxidizing medium; high mechanical strength, can withstand large impact; excellent impermeability, abrasion resistance, easy to clean, decorative effect; lighter weight compared with block It can reduce the load on the structure and the overall cost is low.



It has outstanding effects on the surface protection of buildings and structures, and has a strong pertinence to the ground corrosion problems encountered in the metallurgical and chemical industries. In the design of anti-corrosion structure, epoxy vinyl resin should take the rationality and scientificity of structural design as the key to the durability of the protective structure. Such as the electrolytic tank anti-corrosion structure layer design, the corrosion-resistant glass fiber reinforced plastic layer FRP used has the characteristics of light weight, high strength, good insulation and temperature resistance, good construction technology and design, etc. On the one hand, the glass fibers are bonded into a whole It plays the role of transmitting load, and on the other hand, it gives various excellent comprehensive properties including corrosion resistance to glass fiber reinforced plastic. The composite use with felt structure can further improve its corrosion resistance. For example, the surface resin and chopped felt can contain resin. 0.5 1.4k / m2, called the new grade vinyl resin resin-rich layer or the main corrosion-resistant layer, so the corrosion resistance of glass fiber reinforced plastic depends on the type of corrosion-resistant resin.
