Cinnamic acid: the best materials of metal rust
Air humidity, air temperature, the role of oxygen in the air, the air of harmful gases and impurities, In addition to these factors on the corrosion of metal storage have an impact, there are other factors, such as packaging materials, especially in direct contact with the metal to metal corrosion packaging material to a certain extent, some of the components in wrapping paper contain a considerable amount of chloride ions and acid, and some also contain reduced sulfur. Wrapping of the capillary condensation effect, but also can reduce metal corrosion critical relative humidity. In addition, some microbial corrosion of metals have a catalytic effect. In wet conditions, the iron bacteria can grow and reproduct in the steel, and can promote steel corrosion.
A small number of mold, Aspergillus, such as thinking can promote the corrosion of aluminum in hot and humid conditions, the instrumentation and also because micro-organisms (mainly fungi) cause severe reproductive and corrosion. Microbial’s corrosion of metals, mainly due to the role of microbial metabolites, and sediment effects.
In order to solve the problem of metal corrosion and its products, through scientific research, experts invented the VCI rust. The use of volatile corrosion inhibitors, can be volatile around the metal corrosion and gas, in order to block the corrosive medium on the corrosion products, to achieve the purpose of rust. This method is easy to use, packaging clean, sealed a long period, using a wide range of features suitable for complex and difficult for other anti-rust coating of rust protection of metal products. VCI agents are commonly used dicyclohexylamine nitrite, dicyclohexylamine cinnamic acid, cinnamic acid, formalin, etc.; use a rust VCI paper, VCI powder method, anti-gas solution method rust three.
Due to nitrite, formalin and other harmful to humans and the environment, if reducing the dosage, often rust is not ideal. The acid is a green safety and environmental performance, low production cost, easy preparation and excellent anti-rust black metal vapor corrosion inhibitors, rust-proof metal is now becoming the most
In addition, the acid and the modified polymer film-forming agent consisting of anti-rust liquid can be coated in a special surface treatment of PE membrane produced VCI film. Its black metal has excellent anti-rust, anti-membrane moist, conducive to recycling.
Cinnamic acid has been known as metal corrosion professionals in the best materials.
