What is the glass test tube:
Glass tube is a kind of non-metallic tube in English, which is a kind of glass with sodium oxide (Na2O), boron oxide (B2O3)
and silicon dioxide (SiO2) as the basic components. Its good performance has been recognized by all walks of life in the world.
Compared with ordinary glass, it has no toxic and side effects, and its mechanical properties, thermal stability, water resistance,
alkali resistance, acid resistance and other properties are greatly improved. It can be widely used in chemical industry, aerospace,
, family, hospital and other fields have good promotion value and social benefits. The appearance of this kind of glass in
my country is another new revolution in the basic material industry.
Features:
The linear expansion coefficient of G3.3 borosilicate glass is 3.3±0.1×10-6/K, which is a kind of glass with sodium oxide (Na2O),
boron oxide (B2O3) and silicon dioxide (SiO2) as the basic components. The content of borosilicate in the glass composition is
relatively high, namely boron: 12.5~13.5%, silicon: 78~80%, so this kind of glass is called high borosilicate glass. It belongs to
PYREX glass in borosilicate glass. Acid resistance, alkali resistance, water resistance, excellent corrosion resistance, good thermal
stability, chemical stability and electrical properties, so it has the characteristics of chemical corrosion resistance, thermal shock
resistance, good mechanical properties, and high temperature tolerance. High borosilicate glass (also known as hard glass) is also
called "borosilicate glass 3.3" due to its linear thermal expansion coefficient of (3.3±0.1)×10-6/K. 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 performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light
, source , craft jewelry and other industries. Its good performance has been recognized by all walks of life in the world, especially
in the field of solar energy, which is more widely used in developed countries such as Germany and the United States. The linear
thermal expansion coefficient of borosilicate glass 3.3 is (3.3±0.1)×10-6/K, and its main performance indicators all meet the international
ISO standards, which are the same as the 7740 material of Corning Company in the United States and the material 50 of German
Schott Company. sex. Compared with ordinary glass, it has no toxic and side effects, and its mechanical properties, thermal stability,
water resistance, alkali resistance, acid resistance and other properties are greatly improved. It can be widely used in chemical,
aerospace, family, hospital and other fields. It can be used in various products such as lamps, standard plates, telescope
pieces, washing machine observation holes, microwave oven plates, solar water heaters, etc. It has good promotion value and
social benefits. The appearance of this kind of glass in my country is another new revolution in the basic materials industry.
