Method of Grinding Broken Glass Fibers Using A Glass Fiber Powder Grinding Mill

In the glass fiber production industry, a certain amount of unqualified and experimental discarded glass fiber waste (waste) will be generated during normal production and operation, and the treatment of these glass fiber waste requires a certain amount of manpower and material resources. In order to achieve the goal of zero waste in the glass fiber production industry and reduce production costs, it is necessary to reuse the discarded glass fiber waste filaments. So, how do you produce these ground glass fibers? As a manufacturer of glass fiber powder grinding mills, HCMilling(Guilin Hongcheng) will introduce the methods for grinding broken glass fibers using glass fiber powder grinding mills.

Grinding glass fiber is made by grinding the glass fiber precursor with a glass fiber powder grinding mill. The average length of the fiber is between 30 and 100 microns, and when observed under a microscope, its cross-sectional area is cylindrical. What is the use of ground glass fiber? With the rapid development of science and technology in foreign countries, the application field of ground glass fiber is constantly expanding, and the annual output is also increasing. Currently, there are more than 20 companies producing it, including OCF Company of the United States, which has an annual production capacity of 3300 tons, occupying a leading position in the international market. The traditional filler for friction materials is asbestos. However, it has been reported abroad that asbestos has a cancer risk. In recent years, the international market has resisted friction materials containing asbestos, providing a broad market for ground glass fibers. This high-performance friction material can be widely used as brake and clutch pads for automobiles, brake shoes for passenger and freight vehicles, railway locomotives, and various drilling rigs, friction blocks for stamping equipment, engineering and mining machinery, and tapered brake rings for lifting machinery. It can also be used as a functional filler for ABS plastics to modify ABS plastics to meet the requirements of plastic processing and product application performance. Therefore, the glass fiber powder grinding mill provides good equipment support for grinding broken glass fibers.

The method of grinding broken glass fibers using a glass fiber powder Raymond mill: first, immerse the glass fiber waste in a treatment liquid for treatment, and then take out for washing, crushing, drying, and grinding to obtain the glass fiber waste powder; The specific operation method is as follows: (1) Mix the cement according to the water consumption of 22-28%, fully stir to form a cement slurry, and then take its supernatant after standing for 3-12h; (2) Soak the waste glass fiber in a mixed solution consisting of alkali solution and cement slurry supernatant for 2-72 hours, with a mass concentration of alkali in the mixed solution of 1-15% and a soaking temperature of 30-150 ℃. Wash the soaked glass fiber with tap water and crush it. The broken glass fiber waste is 1-3cm long, and then enter a drying furnace for drying at 120-650 ℃; (3) The dried glass fiber waste yarn enters the interior of the glass fiber powder grinding mill through a continuous feeder, and the powder with qualified particle size enters the glass powder homogenization silo. The particle size of the screened powder is required to pass a 100 mesh sieve.
