First, the main raw material: ultra high molecular weight polyester carborane polymer resin; nanometer molybdenum disulfide; rust sucking Nami Ji group; a mixture of micro-nano powders such as polytetrafluoroethylene. More than a small amount of raw materials wholly manufactured by independent research and I can laboratory.
Second, use: to improve the bearing surface rust resistance; reduce the surface friction coefficient; abrasion wear overall performance.
Third, use recommendations:
1, Remove rust and other oil bearing surface. 1, with our research and development of industrial powder efficient degreasing by 1-3% mixed with water, the bearing ring into this solution, heated to 70 degrees to 85 degrees for 30 minutes (for an intermittent stirring), heating to be stopped from cooled to about 40 degrees one by one bearing ring scrub with a brush dipped in water, in particular the work of a spherical bearing to scrub a few times more, when brushing the bearing ring can not leave the water. Note: This solution can be floating on the surface of oil droplets and then reuse once removed; 2 with 40 degrees rinse twice, this two rinse water can be reused; with 3% of the proportion of heavy oil and heavy with time. multi-cleaning fluid scrub twice;
2, With the LM-1198A-type super-concentrated cleaning solution to remove lubricating oil immersed deep within the bearing phosphate layer porous, as the representative of a resin material such as molybdenum disulfide let out empty location. Specific use 0.5 per cent of the water with a cleaning agent is heated to 85 degrees to 99 degrees (drip down cleaning agent can pick up after the cold surface after removal of floating oil droplets reusable once), immerse the bearing component agent with brush wash, the temperature above 70 degrees and then rinse twice.
3, The basic dry empty water bearing ring into an oven at 60 degrees / 10 minutes and then adjusted to 110 degrees / 10 minutes out; after removal of the generation of high-temperature bearing ring rust easily approach: rapid fall into the sealed barrel, while down while injecting a little ethanol (industrial alcohol), pour a thin layer of spray ring alcohol (do not spray too much), the sealing lid sealed, stored in the bearing ring since the cold barrel seal access. Stored in a sealed bucket is to prevent rust. Only need to take out the coating composition, how much to take sides painted or coated side take immersed in the paint or spray paint. Apply glue stick bearing ring as long as it will not rust, taken promptly after sealing the lid to minimize contact with the air bearing ring. As noted in local humidity conditions or general condition of the seal can be stored for three days -6 days without rust.
Fourth, the basic principle: the use of low surface energy resin material immersed in said nano-bearing shallow because of pure fire, stamping and other produce in the slit and crack phosphate coating surface pores or slits, fully filled only can be seen under a microscope to the bearing surface of the Latitude "gully", so to achieve the purpose of anti-rust performance wear.
Bearings in the surface treatment process, generally used on behalf of a bearing on the working surface immersed in functional nano-materials, make it rust, corrosion, anti-wear (extended life), low coefficient of friction, at high temperature, thermal expansion and accuracy void contradiction balanced handling and overall performance greatly improved conflicting quality indicators has been an excellent balance. This road is one of the most critical process technologies bearing quality.
