High borosilicate glass VS ordinary glass
What is high borosilicate glass?
Many customers ask this question, why is the difference between the two prices so large?
Now let me explain what is high borosilicate glass.
First of all, we need to know what is high borosilicate glass.
High borosilicate glass (also called hard glass) is the characteristic of the use of glass in the high temperature state. After heating the glass inside the glass to complete the glass melting, it is made by the leading production technology, because the coefficient of thermal expansion is (3.3) 0.1 x 10-6/K, and it is also called "borosilicate glass 3.3". It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Because of its excellent function, it is widely used in solar, chemical, medical packaging, electric light source, technical ornaments and other professions. Its outstanding functions have been widely recognized by all circles of the world, especially the application of solar energy, which has been widely carried out in developed countries such as Germany and the United States.
What is the advantage of a high borosilicate glass
The high coefficient of expansion of the high borosilicate glass is that it is no problem to take the glass from the freezer and immediately hold the hot water glass cup, which will not break from twenty degrees to zero, one hundred and thirty degrees. The single layer glass products can be tested directly in the microwave oven and can be put on the open fire to burn 20. No problem, high borosilicate is the most important use of glass products, microwave oven supplies, solar tubes, chemical reactors, chemical reaction containers and so on. It is the safest water supply in the world.
The water resistance and acid resistance of high boron heat-resistant glass are first class, alkali resistance is class A, and the harmful components of glass are less than 0.1%. It is a heat-resistant glass widely used in the country's surface. But generally, heat resistant glass is a real high borosilicate glass, but it is replaced with other glass to reduce the cost.
A customer asks: Why are the cup (hukou) has a prominent small pimple?
This pimple is known as "glass drops" in technical terms, and technical jargon is called "detonation". The node at the mouth of the explosion is a bump like bump, or a small concave mouth. It is the end of the craft glass after the complete formation of the remaining glass solution. It is a feature of the craft made of glass. After that, you can be able to tell whether the purchased products are artificial blowing technology. With the closing at hukou (cup) can prevent certain attraction among the glass accessories. Because heat-resistant glass tea sets are often heated. If the parts are firmly absorbed, the high pressure in the kettle can not be released after heating, and the risk of the difference between the inside and outside air pressure is likely to happen.
Some people ask: a cup of body facing the light, blurred with a circle of texture, knocking does not feel like ordinary glass, why?
High borosilicate glass, as a more advanced glass material, is widely used in chemical medical equipment and high-end cooking utensils in Europe and the United States. The texture is slightly different from the traditional sodium calcium glass. The handicraft glass, in order to form a uniform, the master in the process of blowing the process, the need to continue to rotate the glass embryo, make up the line, this is a special technical scene of the handicraft glass products.
It can be seen that the high borosilicate glass is better than the ordinary glass. So what are the quotations?
Of course, the cost of borosilicate glass is higher than that of ordinary glass, so there must be a distance in the quotation.
The biggest feature of high borosilicate glass is that it has very low thermal expansion coefficient, which is not sensitive to temperature, no common heat expansion and contraction, so it has high temperature and high thermal stability - cold and thermal shock resistance. As far as strength is concerned, there is nothing special about it. Therefore, high borosilicate glass is the best material for making fire resistant glass.
