How to control the quality of pretreatment is the key to stabilize and improve the quality of the coating of the ceramic agent. Only the reasonable design of pretreatment process, fully understand the relevant control elements of each pretreatment process, and carry out reasonable control and maintenance, can ensure the quality of the pretreatment of the ceramic agent.

Advantages of using silane treatment agents

The chemical conversion film technology of silane treatment agent has been applied for more than 10 years. With the increasing attention to environmental protection in China, silane treatment agent has been applied to the pretreatment line of metal industry on a large scale, replacing the traditional phosphating process. The nano-film after silane treatment meets the strict performance requirements of enterprises. Compared with the traditional phosphating, silane treatment agent pretreatment method has the following obvious advantages.

What are the characteristics of silane treatment agent process

With the improvement of people's living standards, individuals and countries have fundamentally changed the importance of environmental protection. The traditional phosphating agent is gradually eliminated. Because the early certifier can not be used in the infiltration line, the film can not be over acid, the unit price is high, it has not been well promoted. In view of the above situation, through the efforts of technicians and engineers, a new generation of silane treatment agent has been developed, which completely overcomes the above defects of the traditional ceramic agent.

Classification and Development Direction of Phosphating Agent

Phosphating agent is divided into iron phosphating agent, zinc phosphating agent and zinc manganese phosphating solution, each product has its different characteristics. 1. Iron phosphating agent, color phosphorus, we sometimes call iron coating agent. The iron-based phosphating agent has low cost, good stability and less pollution; the solubility product of iron phosphate is very small (Ksp = 1.3X10-2), and it can quickly precipitate from the liquid phase with high acidity at low temperature. Moreover, the phosphating liquid film has low porosity and good adhesion to paint, which is an excellent coating bottom layer, so iron-based phosphating is a very promising phosphating process.

Classification of Phosphating and Influence of Phosphating Wastewater on Environment

Pickling and phosphating wastewater is commonly found in electrophoresis, spraying, chemical industry, electroplating and other enterprises, and its pollutants are complex and changeable. Due to their different production processes, some also contain a certain amount of heavy metals such as nickel ions, copper ions or lead ions, as well as surfactants and other pollutants, which are extremely harmful. Moreover, phosphorus can cause eutrophication of water bodies, make the oxygen content of water bodies drop rapidly, and seriously endanger the ecological environment. (Generally speaking, when the total phosphorus content in the water reaches 20mg/L, it is considered eutrophication).
