Water-soluble rust preventive is a commonly used temporary rust preventive material. It uses water as a medium, is safe, convenient and easy to clean, and is one of the indispensable temporary rust preventive in the manufacturing industry.
At present, water-soluble rust preventive is mainly used for rust prevention between processes in metal product processing and metalworking fluids.
As a temporary protection, water-based rust preventive is excellent in short-term rust prevention between metal processing processes, including rust prevention in heat treatment, rust prevention in quenching, rust prevention between machining processes, rust prevention before assembly, and rust prevention before painting.
Chorus Company provides organic polycarboxylic acids, which are very effective ferrous metal corrosion inhibitors.
Water-based rust preventive liquid is the earliest water-based rust preventive. it was widely used due to low cost, easy to use, good rust prevention before. However, nitrite is restricted as a carcinogen nowadays.
The common formula is to use NaNO2 and Na2CO3 together. The two can be applied to different situations by adjusting different ratios. For example, when the parts need to be fully immersed, 3%~5% NaNO2 and 0.5% Na2CO3 are used; when the process requires spraying, 5%~8% NaNO2 and 0.5% Na2CO3 are used.
Chromate-type rust preventive has a good rust prevention effect and is still widely used in some fields. However, chromium can cause heavy metal pollution, so its use is restricted.
Phosphate-type rust preventive liquid can form a hard phosphating film, thereby playing a role in rust prevention. However, the traditional process is complicated, and energy-intensive, and the phosphating residue produced is a hazardous solid waste, which is easy to cause eutrophication of water. Therefore, the phosphating type rust preventive liquid is restricted.
