Dehydration replacement rust inhibitor P3
Application：
1. The dehydration replacement rust preventive is made of environmentally friendly solvents and a variety of special anti-rust additives. After being applied to the metal surface, the solvent evaporates and a uniform anti-rust film remains. It is widely used for long-term anti-rust protection of steel parts.
2. The product has good human sweat and water replacement performance, has excellent anti-corrosion performance for ferrous and non-ferrous metals, and has the characteristics of thin coating, easy to use, and easy to remove. The anti-rust period is as long as 9-12 months.
Product Introduction
Dehydration replacement rust inhibitor P3
Performance advantages:
1. Water displacement type: can quickly remove the water film on the surface of metal parts and attach a layer of anti-rust film on it to protect the metal from corrosion.
2. Low viscosity: has strong permeability and rust resistance, can be used for small hardware parts.
3. Low cost: low cost per unit area.
4. Easy to clean: a transparent oily film is formed on the metal surface, which can be easily washed off with petroleum solvents or kerosene.
Main Application:
1. Mainly used for removing water film and rust prevention on metal surfaces between processes, and is more ideal for the subsequent processing of steel products processed with water-soluble cutting fluids.
2. Widely used for long-term rust prevention of steel parts.
Precautions:
1. This series includes P3 and P3A, of which P3 is not suitable for copper materials and hot and humid environments, and P3A is not suitable for salt spray environments.
2. Immerse the metal parts with water directly into the dehydrating oil for about 1-3 minutes, and vibrate the parts continuously. For parts with pores, blind holes, and inner cavities, they should be shaken to completely dehydrate.
3. The bottom of the oil immersion tank should be designed to be conical, and a valve should be installed at the bottom to discharge the accumulated water at any time. At the same time, a movable metal net should be installed 10cm away from the bottom of the high oil tank to prevent metal parts from touching the accumulated water, ensuring the dehydration and anti-rust effect.
4. If the water droplets are shaken off first and then dehydrated, the effect will be more ideal.
