Benefits of technology

This patented technology involves making strong carbon fiber composites by adding specific chemical substances that are used during production processes or create special shapes called copalons (COPTN) on their surfaces. These structures help connect them together more uniformly without getting worn out quickly due to heavy use over time. They also have excellent resistance against interferers like magnetic fields from electric machines. Overall this makes it ideal for producing high powered tools such as serial motor brushings.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the durability and performance of sophisticated electrical equipment such as industrial AC generators (AC) with multiple phases or multiphase converters due to their use at different speeds and powers levels. Current designs can cause damage from excessive heat generation caused by rapid movement when they come into direct contact during operation.

Embodiment Construction

[0012] 1. Ingredients

[0013] Weigh 30kg of COPNA resin, 40kg of graphite powder and 30kg of synthetic artificial graphite respectively.

[0014] 2. Production

[0015] 1. Mixing: Mix the above materials thoroughly.

[0016] 2. Kneading: put the mixture into the kneading internal treatment with a temperature condition of 120-150°C 2 Hour.

[0017] 3. Grinding: After the kneaded material is naturally cooled to room temperature, it is put into the pulverizer for fine grinding, and then passed through a 100-120 mesh screen, and the sieved fine powder is taken, and the unsifted one is then crushed machine for fine grinding.

[0018] 4. Press molding: put the fine powder in the mold at a pressure of 1.5 tons / cm 3 Forming in the molding, after forming, take off the film, take the formed semi-finished product.

[0019] 5. Sintering: Put the semi-finished product in the sintering furnace, and control the temperature rise and time of sintering:

[0020] It took 6 hours to r...

Abstract

The invention discloses a production method of a conductive anti-friction material of an electric brush, relating to the technical field of motor production and also relating to the technical field of new materials. The production method comprises the following steps of: mixing COPNA (Condensed Polynuclear Aromatic) resin, graphite powder and artificially synthesized Delanium graphite; then kneading, grinding, briquetting and sintering; and finally finely grinding to prepare the conductive anti-friction material of the electric brush. The method provided by the invention can be used for providing a conductive anti-friction material of an SJ905 electric brush, which has the advantages of effective reduction of running abrasion, low noise, small sparks and good anti-interference performance.
