How to passivate the ZSD201 stainless steel passivation solution and how to passivate and process the passivation film and the corresponding experimental parameters. Let everyone feel the charm of fine chemistry and deepen the learning. I learned about the know-how and technical reserves of Shenzhen Zhongshida Surface Treatment Technology Co., Ltd. in the field of stainless steel passivation research.
Passivation mechanism and data analysis of stainless steel "target=_blank> stainless steel passivation solution ZSD201
How is the stainless steel "target=_blank> stainless steel passivation solution passivated? I think everyone is very curious about this aspect. Then we will decipher everyone today, talk about the stainless steel "target=_blank> stainless steel passivation solution ZSD201 The process of how to passivate and the formation of the passivation film, as well as the operational flow and the corresponding standard of experimental parameters, let everyone feel the charm of fine chemistry while learning, and also have a deeper understanding of Shenzhen Zhongshida Surface Treatment Technology Co., Ltd. in the field of stainless steel "target=_blank> stainless steel passivation research and technical reserves.
First talk about the principle of stainless steel "target=_blank> stainless steel rust:
Stainless steel "target=_blank> stainless steel corrosion resistance is mainly due to the addition of a higher content of Cr in the steel, Cr element is easy to oxidize, can quickly form a dense Cr2O3 oxide film on the surface of the steel, so that the electrode of the steel The corrosion resistance in the oxidizing medium is increased, and the corrosion resistance of stainless steel mainly depends on the extremely thin (about 1 mm) dense passivation film covered by the surface. This passivation film is isolated from the corrosive medium. Stainless steel "target=_blank> The basic barrier for stainless steel protection. If the passivation film is incomplete or defective, the stainless steel "target=_blank> stainless steel will still be corroded.
Passivation mechanism for all stainless steel "target=_blank> stainless steel passivation solution:
Stainless steel "target=_blank> stainless steel passivation solution slowly forms a chemical film when it reacts with an object, and the chemical film is formed to interact with a reactive element on the metal surface. What is produced, and it is this kind of active element and the external environment of the atmosphere that will produce corrosion and oxidation. The process of pickling passivation is to change the active nature of this substance into lazy inertness. It is difficult to chemically react with the atmosphere. In addition, a chemical protective film is formed on the surface of the metal to completely insulate the metal surface from direct contact with the atmosphere. This is like a second protective net, and the first protective net is stainless steel. The "target=_blank> stainless steel passivation solution acts to alter the oxidizing active material of the metal, making it an inert substance.
Ok, here's our passivation process and a detailed introduction:
First of all, the first thing we do to passivate is to clean the stains and some oxides, including oil stains, rust, and various materials attached to the surface of the object to be passivated. Because stainless steel "target=_blank> stainless steel passivation solution is very sensitive to these things, if these things are there, our passivation anti-rust purpose will be greatly reduced or abandoned. After the stains, we officially started. Our passivation journey is over.
We infuse the product in the passivation solution for more than 15 minutes, and the time for invading the material is different. Please refer to the instruction manual of the stainless steel "target=_blank> stainless steel passivation solution for the specific foaming time.
After soaking, the object will have anti-corrosion effect. It is the scorpion that is taken out by the horse. We use the data of the salt spray test to speak:
Is it amazing, well, today's Quest is here, and continue to pay attention to Shenzhen Zhongshida Surface Treatment Technology Co., Ltd. (**: http://), which will bring you more passivation knowledge and product knowledge. Please stay tuned!
