Method for treating metal corrosion

Hits：2099 Time：2017-4-20

　　Because of the low cost, short construction period, the main structure of the building can be reused, and so on, the structure of the steel plant, warehouse and so on, so the majority of manufacturing enterprises and warehousing and logistics enterprises as the preferred building. When a large number of metal roof in service time is too long or has exceeded its service life, under the influence of a variety of factors, the metal plate surface protection layer has lost the ability to produce corrosion protection. The environment of industrial buildings is worse than that of civil buildings, and the waste gas, waste water, waste residue and other pollutants produced by industrial production cause corrosion damage to the main building. The exhaust gas such as CO2, SO2, Cl2, H2S etc.; wastewater such as various acid, alkali, salt solution; residue insoluble salt aerosols in the marine atmosphere, especially with a lot of salt and winter use of Cl- containing deicing were easy to rust roof.

State steel structure to bring the following treatment:
Carefully check the metal roof before construction, to ensure that the metal roof is firm, clean, no rust, no ice, do not meet the above conditions are as follows:
A, replace the rusty firmware and add the firmware in the appropriate position;
B, with a grinding machine rust rust area will be polished clean;
C, clear ice, dust and other dirt.
Construction technology:
A, after the roof pretreatment, spraying anti-corrosion primer: Spray (or paint) anti-corrosion primer RFN-CR01.
B, primer dry spray anti-corrosion finish: Spray (or paint) anti-corrosion topcoat RFN-CR02.
