High borosilicate glass tube features

 

The linear expansion coefficient of borosilicate glass is 3.3, 0.1×10-6/K. It is a kind of glass with sodium oxide (Na2O), boron oxide (B2O2) and silicon dioxide (SIO2) as its basic components. The borosilicate content of the glass is relatively high, which is 12.5~13.5% of boron and 78~80% of silicon, so this kind of glass is called borosilicate glass. PYREX glass of borosilicate glass. Acid, alkali and water resistance, excellent corrosion resistance, has good thermal stability, chemical stability and electrical properties, so it has chemical erosion resistance, thermal impact resistance, good mechanical properties, high temperature characteristics.

 

      High borosilicate glass (also known as hard glass), also known as "borosilicate glass 3.3" because the linear thermal expansion coefficient is (3.3 0.1)×10-6/K. It is a kind of special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. 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.

 

 

      The linear thermal expansion coefficient of borosilicate glass 3.3 is (3.3 sco0.1) × 10-6 / K, and its main performance indexes all reach the international ISO standard, which is the same as the 7740 materials of corning company in the United States and 50 materials of schott company in Germany. Compared with common glass, non-toxic side effects, its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties is greatly increased, which can be widely used in chemical industry, aerospace, military, families, hospitals and other fields, can be made into lamps and lanterns, scale, telescope, observation hole washing machine, microwave oven tray, solar water heaters and other products.
