Heat-resistant glass manufacturing materials

Posted by Admin

The glass tea set adopts high borosilicate green glass with a expansion coefficient of 3.3, and its physical and chemical properties reach the national standard. The heat-resistant glass products can be placed between the instantaneous temperature difference of -20 ° c and the normal temperature of 150 ° C without deformation and cracking. The chemical stability, low expansion coefficient and high temperature impact resistance are the most notable features of this type of glass products.

The glass material used for the processing of the glass teapot is borosilicate glass (also known as hard glass), because the coefficient of thermal expansion of the line is (3.3 ± 0.1) × 10-6 / K, which is also known as "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. Due to its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source. , craft jewelry and other industries.

The borosilicate glass borosilicate glass has a very low coefficient of thermal expansion, high temperature resistance, and a temperature difference of 200 degrees. The borosilicate glass is used for the reflective heat-resistant lamp cup of the halogen lamp and the electrical equipment which must use the heat-resistant glass, such as the glass turntable for the microwave oven, the microwave lampshade, the stage light reflection cup, the observation window of the drum washing machine, and the heat-resistant glass teapot cup.
