Phosphating Solution_Workpiece Coating Pretreatment Phosphating Rust Return Causes and Countermeasures!

Hello everyone! Entering July truly marks the arrival of the hot summer season, with the blazing sun making it hard to endure; July is also a season of frequent rain, with short midsummer nights and open windows welcoming the cool breeze. With the arrival of heavy rain, the issue of rust reappearing between pretreatment processes of workpiece coating has become a headache for many customers. Rust on workpieces directly affects the quality of the pretreatment film formation, which in turn impacts the coating effect; therefore, how to effectively prevent rust between processes is one of the key tasks in summer pretreatment coating. Below, we share the causes of rust reappearance during the ceramic treatment process and protective measures.

The development path of metal pretreatment, the development of ceramic agents has triggered a major revolution!

With the development of the times, metal materials are increasingly used in our daily life and industry. For example, steel requires pretreatment processes such as degreasing and rust removal before coating. Then, a chemical conversion film is formed on the metal surface through chemical treatment methods to protect the base metal, enhancing the adhesion of the coating and the corrosion resistance of the metal to some extent. Currently, most processes use phosphating technology. However, with the continuous promotion of energy saving and emission reduction, traditional phosphating can no longer meet modern environmental protection requirements. The application of ceramic conversion agents has brought a significant change to the chemical film formation technology on metal surfaces. The new type of phosphate-free conversion film (ceramic conversion film) is quietly replacing the traditional phosphating film.

How to perform high-performance ceramicizing agent treatment on steel structure building components?

Steel structural building components are increasingly favored by the market, widely promoted and welcomed by customers. However, steel structures also face an urgent problem to be solved: how to perform high-performance ceramic conversion treatment. The key to high-performance metal ceramic conversion agent formulations without "phosphorus chromium" lies in the "process".
