According to the production method, the total quantity of impurities of the quartz sand can be controlled to be within 10ppm, the purity reaches above 99.999 percent, a roasting process of a chlorine furnace is increased, the purity is increased to 99.9995 percent, and the actual industrial production of the high-purity quartz sand is realized.
Description
Technical field
The present invention relates to the production technical field of quartz sand, specifically a kind of production method of glass sand.
Background technology
Along with scientific and technical progress, electric light source, electronic industry, optical communication, SiO
2thin-film material, extensive and super large-scale integration, laser, space flight, the especially high-tech industry fast development such as photovoltaic industry and LED lamp of military project, the demand of high grade quartz sand raw material obtains surprising growth, the SiO2 content requirement is greater than 99.99%, and even 99.9999%.Only have traditionally natural one-level crystal can reach this requirement.Yet the mineral crystal resource is increasingly exhausted, and particularly high grade mineral crystal resource is rare especially, and, in distributed pole imbalance all over the world, 95% crystal concentrates on Brazil and Madagascar, makes country in addition all strive to find substitute.Progressively exhausted due to Crystal Resances, from the seventies in last century, various countries start to explore with the ordinary silicon stone ore and replace crystal to prepare glass sand, the current U.S. level that is in a leading position
.the production technology of glass sand is monopolized by a few countries such as the U.S., Germany, Russia.Invent this technique and solved the deficiency that China produces the glass sand technology, met the quality requirements of downstream industry to glass sand.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of glass sand, by the quartz sand secondary is added to auxiliary material roasting and pickling, be controlled at quartz sand product total impurities in 10ppm, and purity reaches more than 99.999%.
