Issue 20/2015 - Phosphating-free metal surface treatment

A few days ago, Zhejiang Jinhua Flukert Technology Co.
, Ltd.
announced that the metal surface phosphating treatment technology developed by it has made a breakthrough, which not only makes the phosphating process achieve no phosphorus, no fluorine, no heavy metal pollution, but also the treatment effect fully meets the requirements of
industrial application.
The successful research and development of environment-friendly phosphating treatment technology and its products is expected to solve the problem
of wastewater and waste residue pollution caused by phosphating agents from the source.

The environment-friendly phosphating treatment technology and its supporting products developed by the company can automatically remove rust in the phosphating process without phosphorus, fluorine, and heavy metal pollution, simplify the treatment process, and eliminate the five processes
of pickling-washing-neutralization-washing-surface adjustment in the traditional process.

At present, the technology has obtained the national invention patent, the adhesion test (scribing method) of the phosphating treatment effect of the final product has reached level 0, the anti-rust performance salt spray test time has reached more than 500 hours, and the overall technology and its supporting products are lower than the traditional phosphating process
.
The product and supporting process can completely replace the existing phosphating agent and solve the problem
of waste water and waste residue pollution caused by phosphating agent from the source.

Phosphating is the basic process of metal surface treatment, which is mainly applied to the surface treatment of metal basic parts to achieve the purpose of
anti-corrosion.
However, traditional technology also brings environmental pollution in the phosphating process, and its main pollutants are phosphorus, heavy metals and fluorine
.
Once phosphating pollution is generated, it is difficult for existing treatment methods to solve and control pollution in a short time, and the treatment process is long
.
Flucht's new technology enables phosphating-free
metal surface treatments.
