Chemical Resistance Neutral Borosilicate Glass Test Tube 1ml-20ml

Chemical Resistance Transparent Glass Tube

Variety of glass materials, superior performance and good quality, not only can be used as decoration, but also durable and versatile. Glass partitions and car windows must be made of glass. Smooth and flat, pure and bright, all walks of life want it. Glass is now a more popular decoration material, and it is used in architectural interior decoration and outdoor glass curtain walls.

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.
