Summary :Commonly used anticorrosive material includes all kinds of organic and inorganic anticorrosive painting, glass fiber reinforced plastics, rubber products, inorganic panel and so on. Among which anticorrosive painting is the most important anticorrosive material, it has following categories.

Anti-corrosive material is used to restrain chemical corrosion and electrochemical corrosion, commonly used anticorrosive material includes all kinds of organic and inorganic anticorrosive painting, glass fiber reinforced plastics, rubber products, inorganic panel and so on. Among which anticorrosive painting is the most important anticorrosive material, it has following categories:

anticorrosive painting

anticorrosive painting

1.Raw lacquer. Grey brown viscous liquid, resistant to acid, solvent, water, oil and abrasion, strong adhesive force, but it doesn’t resistant to strong alkali and strong oxidant, and high toxicity. Using temperature is 150℃.

2.Urushiol resin painting. Changed raw lacquer’s disadvantages of high toxicity, slow drying and inconvenient to construct, but it doesn’t resistant to sunshine and ultraviolet irradiation.

3.Phenolic resin painting. Good electrical insulating property and oil resistant property, resistant to 60% sulfuric acid, chlorhydric acid, acetic acid and phosphoric acid, most salt and organic solvent, but not resistant to strong oxidant and alkali.

4.Epoxy phenolic painting. Good mechanical property, resistant to acid and alkali, good electrical insulating property.

5.Epoxy resin painting. Good corrosion resistance property, especially resistant to alkali, good wear resistance, paint film has good elasticity and hardness, low shrinking percentage, using temperature is 90 to 100℃.

6.Vinylidene chloride painting. Resistant to industry atmosphere, sea water, acid, oil, salt mist, mould and burning, but not resistant to phenol, ketone, lipid, etc.. Max using temperature is 70℃, it has low adhesive force with metal surface.

7.Asphalt painting. Low price, commonly used, resistant to many mediums, but has worse stability to sunshine, heat resistance is about 60℃.

8.Furane resin painting. Good acid and alkali resistance property, temperature resistance, low price. But worse adhesive to metal, it will shrink after drying.

9.Polyurethane painting. Max heat resistance is 155℃, good chemical resistance, oil resistance, wear resistance and adhesive force, paint film tenacity and electrical insulating property is excellent.

10.Inorganic zinc rich painting. Easy to use and cheap cost, applicable for seawater, water, sea atmosphere, industry atmosphere and oil mediums, heat resistance is about 160℃.

11.New type painting. Mainly includes polyurethane painting, epoxy coal pitch painting and polyethylene anticorrosive painting.
