Problems solved by technology
[0003] At present, clay crucibles are mainly used, but due to the poor quality of glass fiber production and high energy consumption, the relevant departments have banned the application of this product
Domestic manufacturers with economic strength use platinum crucibles to produce glass fibers, but they are expensive (about 400,000 yuan each), consume a lot of power (9.5 degrees / hour), and have low production efficiency (about 6.5kg / hour). Power outage scrapped can not be turned on again

Abstract
The present invention is gypsum mold slip casting process of preparing high melting point polymerized material crucible, and the produced crucible is suitable for use in producing glass fiber. The process includes the steps of: compounding material, ball milling, drying, pelletizing, heat treatment, ball milling, stoving, compounding slurry, injection molding, trimming, medium temperature treatment, punching and shaping, sintering and inspecting. The present invention has the positive effect of producing crucible with smelting point as high as 2000 deg.C, high heat shock resistance, high breaking strength, small heat expansion coefficient.
Description
technical field [0001] The invention relates to a method for preparing a crucible of a high-melt polymer material by using a plaster mold grouting method, and the crucible prepared by the invention is suitable for producing glass fiber reinforced plastics. Background technique [0002] The crucible is the most important equipment for the production of glass fiber by the crucible method, which directly affects the output, quality, power consumption and fineness of glass fiber drawing. [0003] At present, clay crucibles are mainly used, but due to the poor quality of glass fiber production and high energy consumption, the relevant departments have banned the application of this product. Domestic manufacturers with economic strength use platinum crucibles to produce glass fibers, but they are expensive (about 400,000 yuan each), consume a lot of power (9.5 degrees / hour), and have low production efficiency (about 6.5kg / hour). It cannot be turned on again a...
