In the 21st century, with the rapid development of the global economy, the application of metal materials has become more and more extensive, and good development results have been achieved in aviation, automobile, ship, household appliances and electronic communication equipment. At the same time, the requirements for the surface of metal parts are gradually improving, mainly reflected in the high temperature resistance, oxidation resistance, fatigue resistance, corrosion resistance, radiation protection, insulation, magnetic conductivity, conductivity and decoration and other special properties, effectively promoting the rapid development of metal surface treatment technology. At present, the domestic treatment methods for metal surface mainly use phosphating method. Silane treatment technology with high environmental protection effect is still in the process of continuous research and development. At present, some application results have been achieved.

Problems with silane treatment agents:
Answer: Silane treatment agent still has some shortcomings, mainly reflected in the increase of the pH of the silane treatment agent, which will play a certain role in promoting the polycondensation reaction of silanol, but at the same time, the increase of the pH value will also lead to a certain flocculation phenomenon, thus affecting the effect of the treatment agent itself.


Silane treatment agent solutions:
Answer: In view of this situation, the active use of electrodeposition method can achieve good results. In electrodeposition, the corresponding cathodic potential is increased actively on the surface of metal parts. At this time, the pH value of the local solution on the surface of the electrode will increase correspondingly. At this time, not only will it not affect the stability of the bulk solution, but also will make the metal surface adhere to certain organosilane, thus forming a silane film, which has more uniformity. The effect and compactness effect can play a good protective performance.


Secondly, the active use of the way to control the chemical parameters can also play a good effect. For the structure of the silane film and the corrosion resistance, the corresponding silane film can be prepared effectively, which has the same protective effect.
