Completely Cold Polishing Quartz Glass Hemispheric Dome ...
Description
Completely Cold Polishing Quartz Glass Hemispheric Dome / Half Round Bell Jar
With competitive price and timely delivery, CLZ sincerely hope to be your supplier and partner.
This is the first time to do the try of completely cold polishing to quartz glass hemisphric dome/bell jar with a diameter close to 300mm. After many attempts, we have mastered the method. It seems that it can be blown directly, but if we use the blowing method, we can not grasp the better accuracy. At the same time, the dot on the top cannot be removed (this dot will cause optical refraction and affect the use of the equipment). Through this experience, we can make more similar quartz semicircle bell covers in the future.
Fused Quartz Glass Features:
Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.
1. High temperature resistance. The softening point of fused quartz glass is about &#; and can be used for long time working under &#;~&#;. And working at &#; in a short time.
2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature
3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to &#; and putting it in normal temperature water will not crack.
4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.
5. The electrical insulation performance is good. Resistance value of quartz glass equaling to times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
As a leading China fused quartz glass supplier and manufacturer, we are providing best price as well as quality for all kinds of customized fused quartz products. We are also willing to look for long term partners who are a distributor or wholesaler specialized in fused quartz glass in local.
