Detailed Description
Product Introduction
This product is composed of a variety of inorganic and organic compounds. The stainless steel surface is immersed in contact with the passivation liquid to produce a microchemical reaction on the stainless steel surface, prompting the formation of a complete and continuous passivation film on the metal surface, and transforming the original chemically active metal surface into a chemically inert metal surface to achieve isolation and Chemical reaction of external substances, thereby achieving long-term anti-rust effect.
Characteristics and advantages
The liquid is colorless and transparent, easy to use, and the agent can be reused
The chemical process is short and the film is formed quickly, and the anti-rust effect is excellent. The neutral salt spray test is more than an hour
It is safe and environmentally friendly and does not contain heavy metals and other harmful substances. It is nearly neutral and easily biodegradable
Instructions for use
For cleaning and degreasing, use a water-based degreaser to remove oil and degrease. If there are no specific water-based cleaning conditions, it can also be used. Solvent degreasing.
Passivation treatment: Immerse the workpiece to be treated in the passivation liquid, treat it at a temperature of ℃ for more than 2 seconds, take it out and rinse it with clean water.
For solid film treatment, immerse the passivated workpiece in the stainless steel solid film liquid and treat it at a temperature of ℃. After taking it out, cool it in the air for a few minutes and then dry it at a temperature below ℃.
Note that according to the needs of the process, the passivation time can be selected ~ minutes. The specific passivation time will be determined by the user after trial. Products with higher salt spray requirements can undergo secondary solid film treatment.
Suggested process flow
Degreasing, water passivation treatment, flowing water rinsing (times), solid film treatment, air cooling, drying or air drying
The above process can be increased or decreased according to specific circumstances
