Superior Corrosion Resistance Transparent Glass Tube


Compared with common glass, it has no toxic side effects, its mechanical properties, thermal stability, water resistance, alkali resistance, acid resistance and other properties are greatly improved. It can be widely used in various fields such as chemical industry, aerospace, military, family, hospital, etc. Various products such as lamps, standard plates, telescope pieces, washing machine observation holes, microwave oven plates, solar water heaters, etc., 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.


Alkaline earth metal oxide raw material: CaO, MgO, BaO, ZnO, PbO material. Adding CaO and MgO to the glass can reduce the tendency of soda silica glass to crystallize and enhance the chemical stability. It can reduce the viscosity of the glass at high temperatures, to promote the melting and refining of glass. However, when the temperature decreases the viscosity increases rapidly, difficulty forming operation. The raw materials are cited limestone (CaCO3) and dolomite genus sulfur ore (MgCO3), or containing both CaO and MgO. BaO and ZnO are often added to the glass to adjust the refractive index and chemical stability of the glass. The raw materials used are generally industrial zinc oxide and BaCO3, BaSO4 or Ba (NO3) 2. PbO in the glass can be added to significantly improve the refractive index and dispersion, and short wavelength light absorbing glass. At the same time increasing the proportion of the melting temperature decreases, good wettability with the metal. The listed PbO raw materials are red lead, yellow lead or industrial lead nitrate.

Glass is an amorphous inorganic non-metallic material. It is generally more inorganic minerals (e.g., quartz sand, borax, boric acid, barytes, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material, combined with a small amount of auxiliary materials added. of. Its main component is silica and other oxides. Chemical composition of the glass is ordinary Na2SiO3, CaSiO3, SiO2 or Na2O · CaO · 6SiO2 etc., the main component of the silicate complex salt, a configuration is irregular amorphous solid. It is widely used in the building to separate wind and light. It is a mixture. There are also some mixed with metal oxides or salts in the display color of colored glass, and tempered glass produced by physical or chemical means.
