Study on Comprehensive Performance of Low Surface Treatment Primer and Zinc-Rich Primer Supporting System with Rust-Converting Coating Function
In order to solve the contradiction between the demand for low surface treatment and long-term corrosion protection in actual steel structure engineering and the poor anti-corrosion effect of low surface treatment coating and the inapplicability of high anti-corrosion coating with rust,the low surface treatment coating and conventional zinc-rich primer were studied as a primer system,and a series of experiments were designed to explore the comprehensive performance of the primer system on rusty steel plates.The results show that the low surface treatment coating and conventional zinc-rich primer can play a positive synergistic role.Its supporting system can balance the rust-converting construction and high anti-corrosion performance,in addition,it is characterized by convenient construction,good anti-corrosion effect and excellent comprehensive effect,which can provide a good scheme for the actual anti-corrosion project of low surface treatment of steel structures.
