Need to design for the characteristics of brown corundum :
1. Brown corundum is a mixed rubber made from rubber raw materials after mixing in an internal mixer. As a raw material, the formula is designed according to the characteristics of the brown corundum and the required product hardness is determined. The product is molded by a rubber flat vulcanizing machine. After the product is formed, the flashing treatment is finally performed to smooth the product surface without burrs.
2. When brown corundum is molded, it is pressed by high pressure, and its cohesion due to the elastomer can not be eliminated. When the mold is released from the mold, it often produces extremely unstable shrinkage. It must take a period of time to be gentle and stable.
Third, the temperature range of molding and solidification of brown alumina is also quite different. It can even be affected by indoor humidity due to climate change. Therefore, its production conditions need to be appropriately adjusted at any time, which may cause differences in product quality.
Therefore, when the brown corundum is designed, it is necessary to calculate the coordination carefully regardless of the formula or the mold. If not, the product size is likely to be unstable and the product quality will be lowered.
