Corrosion of steel buildings prefabricated supplier corrosion treatment

Analysis of prefabricated building supplier corrosion treatment, and are not free to add diluent. Coating Performance : To consider the various harmful effects of media on the steel structure , select the appropriate working environment spray coating to ensure corrosion quality.

1.to take measures in accordance with the level of corrosion
Corrosion of steel buildings can be divided into strong , medium and weak , no four . In strong corrosion ( a lot of CO2, SiO2, H2S industrial environment ) conditions, material corrosion speed, isolation components and parts must be taken to protect the surface ; corrosion under moderate conditions, the material has some rust, can be used to improve the member 's own weight , or using a simple surface protection ; corrosion under weak conditions, materials corrosion is slower , but still need to take some measures ; under conditions no rust , corrosion material is very slow or no obvious signs of rust , components and parts can not take protective measures.
2.the key to treatment
Primary treatment : Anti- corrosion steel primary treatment to be qualified to meet the specific requirements of design drawings , such as the use of alkyd enamel , epoxy zinc-rich paint , CSM , galvanized .
Temperature and humidity : Ambient temperature and relative humidity during coating shall conform to product requirements , the ambient temperature should be at 5-38 ℃, relative humidity should not exceed 85% , shall not be dew coating the surface . After the coating shall not rain within 4h.
