Extending the service life of ceramic/ Porcelain glove former is a comprehensive problem in many aspects, combined with our analysis, the following measures are proposed:
- From the glove production line, the length of the upper oven can be extended, and the temperature of hand mould out of the oven can be reduced from about 170°C to about 130°C (or lower), which is very important to improve the service life of the ceramic hand mould.
- Improve the mechanical strength of the ceramic hand mould material, while reducing the coefficient of thermal expansion of the material, which can be solved to a limited extent within a certain range. But if you want to improve significantly, the only way is to change the ceramic hand mould material (but not completely solved), but then the cost of the hand mold will be much higher, thus limiting the glove company’s pursuit of profit.
- Adding gangue to the ceramic hand mold, the strength of the porcelain hand mold will be increased by 30%, that will significantly reducing production costs and effectively using the three wastes.
- The use of clean gas (natural gas) combustion to produce a large number of mullite crystals greatly improves the strong alkali resistance and mechanical strength of the hand mold. The cost of the ceramic hand mold can be reduced, thereby increasing the added value and economic benefit of the product.
- The glove mold uses coal gangue to replace alumina and most of the mullite in the raw material processing, which not only reduces the ball milling time by 1/3, but also improves the density of the product, thereby reducing the ball milling time from the original 25h to 15h. The energy saving effect is remarkable.
- High-strength alkali-resistant ceramic glove molds need to add 50% gangue to the raw materials.
