How to identify the trombone quartz stone
Drawing is one of the glass forming process, quartz stone was heated and melted into a certain viscosity of the liquid, through the special forming rod and forming device, the molten glass tube after cooling in liquid form.
The process of tube for feeding, melting, forming, cooling, drawing. General quartz can slide, is the different quality requirements, if required, transparent no bubble, it should use silica of high purity, less gas-liquid inclusions of quartz stone, processed into high purity quartz sand to the trombone.
The process is made of quartz material raw materials. What are the specific quartz material you can use Baidu. Then fused quartz material by drawing etc., also can check electric melting technology and equipment. Baidu China from 60s the size of the quartz tube production enterprises. As for the identification. According to the material processing material. Are different, such as synthesis of SIO4, gas refining quartz sand need, pipe is pulled out of quartz material and quartz stone are not necessarily linked,
