High-quality raw materials are the basis of high-quality products. Quartz glass raw materials have always been an urgent problem to be solved in the quartz glass industry. This problem is particularly important in the current situation of foreign imports of large quantities of raw materials.
China's transparent quartz glass production raw materials are mainly produced in the East China Sea region, and its ore quality is good, but the production equipment and technology are backward, resulting in poor product quality. Since the 1980s, the quartz glass industry has been calling for unified raw material extraction to improve the quality of raw materials, but There is no breakthrough in raw material processing. Due to the quality of raw materials, the quality of quartz glass products in China is poor, and the military products and export products have low yields and the cost remains high. In the 1990s, imported raw materials were imported in large quantities for quality advantage, and most of the domestic raw material production enterprises stopped production. This situation is very unfavorable to the development of the quartz glass industry in China. In addition to the loss of profits, it is also detrimental to the development of high technology in our country and to the defense industry. The special raw materials we need cannot be guaranteed and the technology cannot continue to develop. To this end, we should develop our own raw material industry to a strategic height.
research content:
1. Strengthen basic research. According to the characteristics of China's ore and actual needs, the analytical methods and grading standards for quartz glass raw materials are established. You can't mix high-quality raw materials with inferior raw materials or use them to produce low-grade products.
2. Unified prospecting and planning for mining. Focus on supporting good, good quality raw material plants, strengthening technical strength, and scale management, establishing raw material warehouses at all levels above 10,000 tons, and improving the consistency of raw materials. Gradually reverse the current chaos, scattered, small, individual mining situation.
3. To study the purification process of quartz glass raw materials suitable for China's national conditions, eliminate impurities and reduce the content of impurities.
31. Elimination of trace amounts of mica and feldspar in raw materials.
32. Research to reduce metal ion content. For the production of quartz glass for the electronics industry.
33. Study on hydroxyl in raw materials. For the production of electric light source with high quality low hydroxyl silica glass.
4, in-depth study of silica processing technology; driven by the continuous melting technology, in recent years, silica substitute crystal for quartz glass production has made a breakthrough. A batch of raw material plants for processing silica has emerged, which has expanded the source of raw materials and reduced the cost, which has created conditions for reducing the cost of quartz glass for electric light sources in China and expanding exports. However, these raw material plants lack technical strength. There is an urgent need to strengthen scientific research guidance, optimize production processes, and standardize them.
