What are the composition and characteristics of the phosphating agent?
The principle of the phosphating agent is that the phosphating solution itself reacts with the substrate to generate a dense chemical conversion film on the surface of the substrate to protect the substrate. Phosphating agent is widely used in professional spraying factory pretreatment of a chemical, can give the spray workpiece to provide a short-term anti-rust and paint, powder, such as a good adhesion to the bottom layer.

What are the characteristics of the use of ceramic agent?
The requirements for the process of the ceramic agent are not very high. Even if the phosphating process has been done before, if the ceramic process is to be replaced and the tank body is cleaned, the ceramic process can be directly replaced. The dosage of the ceramic agent is only about 20% of that of phosphating, the use cost is lower than that of phosphating, and the pollution to the environment is reduced. At the same time, the cost of sewage treatment is also reduced.

Preparation Method and Application of Ceramics
The certicizing agent is a so-called phosphorus-free converting agent, such as zirconium, zirconium titanium, silane, zirconium silane, and the like. It can replace phosphating solution, and the compound effect of fluorozirconate and silane coupling agent is better. The nano-ceramic coating composed of zirconium salt is mainly used to replace the traditional crystalline phosphating protective layer, and has excellent adhesion and excellent anti-corrosion function with the metal surface and subsequent coating.

Process Flow for the Use of Ceramics
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.
