Benefits of technology

This patented technology allows an improved type of car's paint called molten pigmented bituminum (MPB). It uses special materials made up mostly of iron flakes mixed together into liquid or paste state at room temperatures before use. These particles help make the paints stick better when used over longer periods of time without getting worn out easily due to their low melting point compared to other types of coatings such as epoxy resin. Additionally, adding certain metals like tin may further increase its durability against abrasion while maintaining desired properties. Overall, this new method provides technical benefits including increased strength, less wearing away during cleanup operations, lower pressures required, more accurate measurements, higher precision, stability, reliable manufacturing processes, etcetera

Problems solved by technology

Technological Problem: There currently exist two types of brushing called AC (Alternate Current) and DLB (Direct Linear Block). These brashes can be made by different methods like casting, welding, machining, plasma spray coating, etc., but they lack their technical features needed for efficient power transmission due to factors including limited durable lifetimes, difficulty cleanings slippage rings when worn out, insufficient lubricant quality, excess heat generation, and difficulties associated with replacing damaged parts after installation.

Embodiment Construction

[0014] The present invention will be described in detail below through specific examples.

[0015] A metal graphite brush with high accuracy and high reliability, made of the following parts by weight (kg) of raw materials: flake graphite 58, pitch 23, tungsten disulfide 24, iron powder 4, copper sulfide 8, manganese carbonate 13, Copper antimony alloy powder 8. Oleic acid is appropriate;

[0016] The metal graphite electric brush with high precision and strong reliability according to the present invention is made by the following specific steps:

[0017] (1) Heat the asphalt to melt, add iron powder, mix and stir evenly, after cooling, the modified asphalt is ready for use;

[0018] (2) Dissolve the modified asphalt with carbon tetrachloride to obtain a solution with a 2% asphalt content. Take the 30% modified asphalt solution and copper-antimony alloy powder and mix and stir evenly, then mix with tungsten disulfide and stir evenly, and add to the oven After removing the solvent in th

Abstract

The invention discloses a metal electrographite brush having high precision and good reliability. The metal electrographite brush is characterized by being prepared from raw materials by weight: 40-60 parts of crystalline flake graphite, 18-28 parts of pitch, 20-30 parts of tungsten disulfide, 3-5 parts of iron powder, 6-9 parts of copper sulphide, 11-15 parts of manganese carbonate, 7-9 parts of copper-antimony alloy powder and an appropriate amount of oleic acid. By adding the copper sulphide, an effect of enhancing conductivity and hardness of brush material is enhanced. By adding manganese carbonate, effects of reducing sintering temperature and improving material compactness are improved. According to the invention, the metal electrographite brush prepared by adopting the scientific formula and a reasonable material proportion has good hardness and conductivity, is high in accuracy, stable in quality, good in reliability and worth of promotion.
