Borosilicate glass how to distinguish between good and bad

Date：2024-06-23

Borosilicate glass, as an emerging glass material, is widely used in chemical and medical equipment, as well as high-end European and American kitchenware production. Slightly different from ordinary soda-lime glass. Handmade glassware, handmade, in order to molding uniformity, the master in the blowing process, the need to constantly rotate the glass embryo, molding art, which is unique to the handmade glass products of the normal process phenomenon.

1, what is borosilicate glass cups

High borosilicate glass, is the use of glass at high temperatures in the conductive properties of the glass melting by heating the glass inside the glass, processed by advanced production technology, due to the linear coefficient of thermal expansion of (3.3 Shi 0.1) × 10-6 / K, also known as "borosilicate glass 3.3". It is a low expansion rate, high temperature, high strength, high hardness, high transmittance and high chemical stability of the special glass materials, because of its excellent performance, is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries. Its good performance has been widely recognized by all walks of life in the world, especially in the field of solar energy is more widely used, Germany, the United States and other developed countries have been more widely promoted.

2, borosilicate glass has what advantages

Borosilicate glass coefficient of expansion is high in layman's terms is to take the glass from the freezer out right away on the hot water just opened the glass will not break minus 20 degrees to minus one hundred and thirty degrees is not a problem, single-layer glass products can be directly into the microwave oven I personally tried and can be placed on an open fire dry burning for 20 minutes without a problem, borosilicate Z is mainly to do with glass products microwave oven supplies solar tubes Chemical reactor chemical reaction containers, etc. Widely used is currently the world's Z safe drinking water supplies.

High boron heat-resistant glass water resistance, acid resistance for the first grade, alkali resistance for the A grade, glass harmful components less than 0.1%, is widely used at home and abroad, heat-resistant glass, but the general heat-resistant glass is not necessarily a real high borosilicate glass, but with other glass alternative to reduce costs.

Of course, the cost of high borosilicate glass is higher than ordinary glass, so there is certainly a difference in price.
