8. The process is simple and the process is short.

9. Comprehensive cost, product consumption, three waste treatment costs are low.

The silane treatment agent is compatible with the existing coating process and coating equipment, and can be put into production only by replacing the silane treatment agent without equipment modification.

Silane treatment agent is mainly used for film-forming treatment of steel workpieces, which can form a golden yellow-blue film on the surface of the workpiece, improve the adhesion and anti-corrosion function of the workpiece, and protect the metal for a long time. Silane treatment agent is environmentally friendly and fast, in order to produce better results, but it needs attention during use:

1. In order to obtain good quality film performance and extend the life of the bath, pure water should be used.

2. In order to reduce the erosion of the groove and the loss of the effective components of the silane treatment agent, it is recommended to use materials other than cast iron for the groove body, such as stainless steel above 304, glass fiber reinforced plastic lining, cast iron tanks with hard PVC and PE lining.

3. The change of phosphating line to silane treatment process requires thorough cleaning of phosphating slag.

4. Please read the instructions carefully for use. For those who have no experience, please use them under the guidance of technicians.

The main advantages of phosphating agent using spray method

2023-05-04

The role of phosphating agent is obvious to all. It can not only bring rich benefits to modern machinery production, but also make new breakthroughs in improving the overall processing quality. With the continuous introduction of technology, the type of phosphating solution has also undergone many changes. Medium temperature phosphating solution, slag-free phosphating solution and galvanizing phosphating solution are all representatives of technological innovation. In order to give full play to its use value, manufacturers need to improve the operability of the spraying method, then, the following together to understand the main advantages of phosphating agent using spray method! On the one hand, manufacturers in the use of phosphating agent, comparative analysis of applicable methods. If the phosphating agent is sprayed directly on the surface of the workpiece, the formation speed of the phosphating film is much faster than that of the workpiece immersed in the same phosphating solution, or the phosphating can be carried out at the same time at a lower temperature. In the iron-containing phosphating solution, the iron ions will be oxidized by the atmosphere during the spraying phosphating process, so the spraying phosphating method cannot be used for iron salt phosphating. The spraying method is also not suitable for high-temperature manganese salt phosphating because the heat loss is too large. On the other hand, the spraying method is a method accepted by many manufacturers. The advantages are as follows: 1. The phosphating solution in contact with the metal surface is always fresh. Soaking methods are different. The phosphating solution in contact with the metal surface will gradually lack the film-forming ions, which can only be formed by the diffusion of the phosphating solution from a distance.

The Difference of Phosphating Agent

2023-04-12

Now a lot of phosphating agent, so we are not unfamiliar with phosphating agent, but we know the difference between good phosphating agent and poor quality phosphating agent. However, good phosphating agents are quite different. Good phosphating agent has more advantages in use effect and cost, so, let's understand the difference between the advantages and disadvantages of phosphating agent together! 1. The coating speed is fast. Compared with inferior surface adjustment, good surface adjustment can completely coat the film in a short time, especially on the spraying line. Its advantages are inferior surface adjustment can not be compared. 2, good anti-rust performance, due to the high quality surface conditioning gel peptide particles have reached the nanometer level, high activity, the resulting phosphating nucleus is extremely fine, so it has a strong anti-rust performance. 3. Cost saving and good surface adjustment quality. Due to the dense phosphating film, it will not produce secondary crystallization. In the case of good anti-rust performance, the amount of phosphating solution can be reduced. According to the analysis of experimental data and the actual use of customers can save 10% of the phosphating solution. Because the phosphating film is thin and dense, it is also a big advantage for saving paint. Compared with powder spraying, due to the thicker coating and the operating habits of spraying personnel,

Analysis on the Development Potential of Phosphating Agent Industry

2023-03-20

Phosphating agent technology has been developed for more than 100 years. For more than 100 years, phosphating technology has developed from a simple chemical corrosion method to a complex and comprehensive technology. The application scope of phosphating treatment technology has also developed from the initial metal anti-corrosion to today's metal coating pre-phosphating treatment, metal wear-resistant phosphating treatment, metal anti-corrosion phosphating treatment and metal plasticizing treatment. Phosphating treatment and other applications before denaturation processing, then, let's understand the development potential analysis of phosphating agent industry together! Statistics show that China's phosphate rock reserves account for 5.7 of the world's total, ranking second in the world, with an average grade of about 17%, of which intermediate phosphate rock (grade above 30%) accounts for only 16.7, while the price of phosphate rock in India is 210 US dollars/ton (68-70% BPL), equivalent to the domestic price of 1432 yuan/ton, which is about 1.5 times higher than the price in Hubei market. "China's phosphate rock 'many but not rich', high-grade phosphate rock is very scarce, the price difference at home and abroad is huge." Analysis of the development potential of the phosphating agent industry Phosphating agent refers to the chemical sub-industry that uses phosphate rock as raw material and processes the phosphorus element in the ore into products through chemical methods.

What are the problems of phosphating agent?

2023-02-08

What are the problems of phosphating agent? The role of phosphating agent is mainly in two aspects: on the one hand, the phosphating agent plays the role of cathodic depolarization in the process of forming chemical conversion film, which promotes the normal progress of electrochemical conversion reaction, so as to ensure the normal progress of chemical deposition reaction, that is, the formation of chemical conversion layer. On the other hand, these accelerators are mostly oxidizing species. During the chemical conversion treatment, the ferrous ions dissolved in the iron-containing metal material treatment solution are oxidized to ferric ions, thereby preventing the enrichment of the ferric ions during the chemical conversion, preventing the aging of the chemical treatment solution due to the enrichment of the ferrous ions, and preventing the possibility of a good conversion layer. However, each of the regular chemical conversion phosphating agents has various problems to be solved. A wide range of sulfites are not stable in acid solutions and must be added continuously as an ingredient during use to replenish the amount of sulfite equivalent to consumption, thereby keeping the concentration of nitrous salt constant. More importantly, a part of the phosphite is converted into NOx gas during the oxidation or natural decomposition reaction, and the obtained NOx gas is diffused into the atmosphere and causes pollution. Chlorate alone is less effective when used as a chemical conversion phosphating agent. It is usually chemically transformed with another

What is the phosphating agent? Phosphating is a commonly used pretreatment technology. In principle, it belongs to chemical conversion surface treatment, which is mainly used in the phosphating of steel surface. Non-ferrous metals (such as aluminum and zinc) can also be used for phosphating. Phosphating is the process of chemical and electrochemical reaction of phosphate chemical conversion surface, called phosphating surface. The purpose of phosphating is mainly to provide protection for the base metal and prevent metal corrosion to a certain extent; it is used as a primer before painting to improve the adhesion and corrosion resistance of the paint surface; it plays a role in the cold working of the metal. Anti-friction and lubrication. The principle of the phosphating agent is that the chemical liquid itself reacts with the substrate, and a void-free chemical conversion surface layer appears on the surface of the substrate to protect the substrate. Phosphating agent is a kind of chemical widely used in the pretreatment of professional spraying plants. It can provide temporary rust prevention and good adhesive layer of paint and powder for spraying workpieces. Classification: Iron phosphating agent It is a light blue acidic coating that can appear on the surface of steel, zinc and aluminum with a thickness of 0.8-1.7 μm. It is the surface of yellow, red and blue. It has good compatibility with electrophoretic coating and powder coating, making the thin surface layer resistant to bending, deformation and strong resistance. The single-liquid product has stable performance, almost no precipitation, convenient tank management, and elimination.
