Bearing surface treatment technology

I. Main raw materials: super polymer polyester carborane polymer resin; nano-molybdenum disulfide; anti-rust and oil-absorbing nano-groups; micro-tetrafluoroethylene and other mixture nano-powder. All the above materials are independently developed by our institute and can be produced in small quantities in the laboratory.
Second, use: improve the bearing surface rust resistance; reduce surface friction coefficient; comprehensive performance of friction and wear resistance.
3. Suggestions for use:
1. Remove rust and other oils on the bearing surface. 1. Use our developed industrial high-efficiency degreasing powder to mix with water at 1% to 3%, put the bearing ring in this liquid and warm it to 70 to 85 degrees for 30 minutes (intermittent stirring), stop heating and wait for After cooling to about 40 degrees, immerse the bearing rings in water one by one and brush them with a brush, especially the working spherical surface of the bearing should be brushed several times. The bearing rings cannot leave the water surface during brushing. Note: This liquid can be reused after removing the oil droplets floating on the water surface; 2. Rinse twice with water at about 40 degrees, these two rinse water can be reused; when the oil is heavy, use 3% ratio and reconstitute Brush the cleaning solution twice more;
2. Use LM-1198A ultra-concentrated cleaning solution to remove the lubricating oil in the deep pores of the phosphate layer of the bearing, so as to make room for the resin substituted with molybdenum disulfide. The specific method of use is to heat the water-containing cleaning agent to a temperature of 85 to 99 degrees at a ratio of 0.5% (the cleaning agent can be connected after cooling down and can be reused after removing the oil droplets floating on the surface). In the preparation, use a brush to wash once, and then rinse twice with water at a temperature above 70 degrees.
3. Put the bearing ring that is basically empty and dry into the oven for 60 degrees / 10 minutes and then adjust it to 110 degrees / 10 minutes. Take out; the bearing ring with high temperature after taking out is easy to rust. Handling method: Quickly pour Into the sealed bucket, spray a bit of absolute ethanol (industrial alcohol) while pouring, pour a thin layer of alcohol (do not spray too much), seal the sealed bucket lid, and store the bearing ring in Take out after cooling in the sealed bucket. Storage in sealed drums is mainly to prevent rust. Take it out when you need to apply paint, and apply as much as you can, or dip in or spray with paint. As long as the bearing ring is coated with glue, it will not rust. Seal the bucket cover in time after removing to minimize the contact of the bearing ring with air. 椐 The local environmental humidity or sealed condition can generally be stored for 3-6 days without rust.
Fourth, the basic principle: the resin with a lower surface energy is used to immerse the above nano-materials into the shallow surface of the bearing due to fire, stamping, etc., resulting in cracks and micro-holes or gaps on the surface of the phosphating film. The vertical and horizontal "ditch" on the bearing surface can achieve the purpose of rust and wear resistance. In the surface treatment process of bearings, bearings are generally immersed in functional nanomaterials on the working surface to prevent rust, corrosion, wear (extended life), low coefficient of friction, high temperature resistance, and high thermal expansion accuracy The comprehensive performances such as the processing of the void contradiction balance have been greatly improved, and the contradictory quality indicators have been perfectly balanced. This process is one of the most critical technologies for bearing quality.
