What is a heat-resistant glass

    With the gradual lifting and safety awareness for consumersGlass ProductsGradually deepened safety, environmental protection, health, easy to clean and so understanding, but also due to the heat-resistant glass production technology has matured and widely used,Heat-resistant glassAlready out of the use of traditional laboratory glassware category, a large number of heat-resistant glass tableware cookware into hotels, restaurants and ordinary people's lives, thus accelerating theChina Glass ProductsBooming industry. Heat-resistant glass tableware cookware heat resistance and diverse series of products to improve the quality of life of the people, enriching the lives of the people.

What isHeat-resistant glass

With the popularity of heat-resistant glass tableware cookware to use, there have been problems can not be ignored, the concept of "heat-resistant glass tableware cookware" is not clear, the product is not clear, uniform quality standards, lack of standardized production, the market also appeared to use posing as ordinary soda-lime glass heat-resistant glass and other audiovisual confuse bad behavior, and even thus resulting in wounding incident occurred, seriously damaged the interests of consumers.

So what kind of glass can be called a heat-resistant glass it? Heat-resistant glass is an ability to withstand thermal shock caused by strong thermal shock (thermal expansion coefficient), the use of high temperature (temperature and strain softening temperature high) glass , also known as hard glass.

The main properties of heat resistant glass is thermal shock resistance, can be used normally at 550 ℃ high temperature environment, the unique physical and chemical properties determine the glass is a genuine all-powerful, versatile material. Heat-resistant glass has the following characteristics: excellent thermal properties, good thermal shock properties, expansion coefficient; has a high light transmittance and surface roughness; not only has a high resistance to thermal shock, but also has a high surface hardness, scratch can be prevented; than the density of soda-lime-silica glass is about 12% lower; acid addition good alkali resistance, it also has a very good resistance to hydrolysis, than the two grades of soda-lime-silica glass not due to moisture in the air to cause water molecules in crack propagation.

Generally, heat-resistant glass is a borosilicate glass nicknames, but glass-ceramics, high alumina glass and some special glass also due to good heat resistance and classified as heat-resistant glass. Heat-resistant glass can be classified according to the nature of the different glass types, uses, heat-resistant temperature.

Heat-resistant glass is very versatile, the main heat-resistant glass used to manufacture laboratory instruments, such as burning and gauges. Can also be used in the manufacture of industrial reaction tank, reactor, complete sets of chemical equipment and transportation pipelines. In the civil context, forManufacturing pan, Soup, a variety ofDining utensilsAnd so on.
