Anti - corrosion process editor for epoxy powder
Principle of treatment of anticorrosion technology
The pretreatment quality has great influence on the performance of the coating. There are many examples in the actual coating process due to poor pretreatment and less than expected corrosion protection. In particular, many excellent anticorrosive coatings can only form normal coating according to their respective requirements, and achieve the expected corrosion protection.
The steel base material must be derusted, deoil, phosphating treatment.
The protective coating thickness must exceed its critical thickness to play a protective role. Generally, it is 150 mm ~ 200 m.
If the primer is coated for a long time, it will be difficult to attach and affect the overall protective effect.
