Information
When the steel structure is exposed to the environment, corrosion is inevitable, especially the common rust. Under the chemistry of the aggressive medium, good steel will produce various corrosion. As far as the current aggressive media are concerned, there are three types of acid corrosion, alkali corrosion and salt corrosion. If it is divided according to its different forms, it can be divided into two categories: liquid phase corrosion and gas phase corrosion. In addition, among environmental factors, atmospheric humidity, rain, atmospheric dust and temperature will also act on the surface of the steel, and all contact surfaces will cause corrosion of the steel. Different steel materials constitute different metal elements, and the corrosion mechanism is also very different. Some are strongly acidic, some are weakly acidic, some are oxygenated acid corrosion, and of course some are acid corrosion, and these are Different acids, as the temperature continues to change, the degree of corrosion is also very different, but the higher the temperature, the stronger the degree of corrosivity.
The acid corrosion resistant anticorrosive paint solution is made up of an inorganic polymer chelate synthesis film solution, which has a siloxy-Si—O—Si— bond as the base, grafted with an organic alkyl side chain as an auxiliary, and the hydroxyl group is end-chain chelated. Membrane, the anti-corrosive paint molecular bond has excellent anti-corrosion ternary synergy effect on the chelating hydroxyl group and alkyl group on the silicon atom, the solution stability is strong, the influence on the interior of the polymer is alleviated, and the film forming material is denser. Strong adhesion and high temperature resistance. It can be used to prevent the corrosion of the steel frame structure of the workshop, such as uniform corrosion, uneven corrosion, point (pit) corrosion, stress corrosion, hydrogen embrittlement and other metal corrosion, completely solve the stress corrosion and hydrogen embrittlement of the steel frame structure of the workshop. In the case of deformation precursors, brittle fractures occur suddenly, preventing the onset of risks and ensuring the safety of industrial production.
