Coating classification: a new type of coating assistant corrosion inhibitor

Core tip: Introduction: coating corrosion inhibitor is mainly used in metal anticorrosion In the process of metal anticorrosion, adding some special materials in the treatment process can obtain much higher anticorrosion effect than not adding special materials These special materials are called "corrosion inhibitors" The inhibitor has chemical activity, which can change the electron transfer between the organic coating and the coating (mainly refers to the metal) to the outside world, and increase the corrosion resistance of the coating and the coating metal (10-20 times) Features: the features of the paint inhibitor are as follows: (1) use Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Introduction: paint inhibitor is mainly used in metal anticorrosion In the process of metal anticorrosion, adding some special materials in the treatment process can obtain much higher anticorrosion effect than not adding special materials These special materials are called "corrosion inhibitors" The inhibitor has chemical activity, which can change the electron transfer between the organic coating and the coating (mainly refers to the metal) to the outside world, and increase the corrosion resistance of the coating and the coating metal (10-20 times) Features: the features of the inhibitor are as follows: ① small amount of use and moderate price, which will not significantly increase the cost of organic coatings; ② no pollution or small pollution in production, which is easy to carry out environmental protection treatment; ③ large production safety factor; ④ single component is preferred in the inhibitor molecule, and the composite products are relatively stable with long storage stability; ⑤ In the electrochemical corrosion environment, the inhibitor has a strong "polarization" effect on the metal anode and cathode; ⑥ the inhibitor has affinity for various materials (resin, pigment, filler, auxiliary agent, solvent) in the paint; ⑦ the inhibitor is easy to disperse in the paint; two kinds of paint inhibitors: GA and SA are synthetic chemicals, the former is alkaline, the latter is acid, so their application occasions are different The unpolymerized monomers in resin and soluble salts in pigment have a great influence on the function of corrosion inhibitor of paint, which should be tested or removed carefully before use Generally, the amount of inhibitor used in the coating is 1-2% of the solid content of the coating For the majority of users, as long as the anti-corrosion requirements of the coating in the market are met, it should be added less rather than more Coating resin is the best type molecule, followed by reticular molecule and linear molecule The effect of the coating containing inhibitor is the best on the metal conversion film (phosphating film, manganese chromate film, oxalate film) Because the coating inhibitor and the conversion film have slow-release synergistic effect If there are curing agents in the coating, most curing agents and corrosion inhibitors have slow-release synergistic effect Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
