替代氢氧焰熔融水晶制备全透明石英玻璃的石英砂中ppm级羟基剔除机理研究

This project will be launched from alternative oxyhydrogen flame melt crystal preparation of transparent quartz glass 0.18 0.27 mm quartz sand hydroxy out of PPM level. It can make their own enthalpy entropy increase friction, increase temperature surge, corresponding to the pressure trajectory by hydroxyl molecular absorption of high frequency electromagnetic wave, analyze its in Brownian motion state and the distribution of thermal stress cracking wall jet process after the weak place, explore to PPM level inside quartz sand grain hydroxy process mechanism, solve the problem of its profound theory and technology. This study used mineralogy, engineering thermodynamics, reaction kinetics and heat transfer law of enthalpy, entropy and principle of thermal stress to study the cause of the hydroxyl groups in quartz sand, heated by high frequency electromagnetic wave produced thermal stress, the process of spray to crack and quartz sand particle size change process, and then use the "0.618" golden coefficient test to explore the mechanism of the technology to build four dimensional mathematical model for guiding instead of oxyhydrogen flame preparation of transparent quartz glass melting crystal quartz sand PPM level of hydroxyl groups.This project is that a new idea is put up aimed to develop new nearly dried up a mineral materials , establish the theory instruction model to guide the engineering development and application, to improve the transparent quartz glass products at home and abroad, especially the quality of raw materials, reduce cost and consumption, improve the economic and social benefits, and could implement relevant industry comprehensive upgrade the level of high-tech industry.
