The main raw materials of high borosilicate glass tube, Yaohui glass small to present you

According to the nature of the introduced oxides, divided into acid oxide raw materials, alkali metal oxide raw materials and alkaline earth metal oxide raw materials.

　　①Acidic oxide raw materials: raw materials with SiO2, B2O3, Al2O3, etc. SiO2 is the skeleton of the glass structure in silicate glass. It gives the glass high strength, good chemical stability, heat resistance and low expansion, but will make the glass melting temperature increases, viscosity increases. SiO2 cited raw materials are silica sand or sandstone, quartzite. B2O3 in the glass, can reduce the thermal expansion of glass, improve refractive index, heat resistance and chemical resistance, at higher temperatures can reduce the glass viscosity, lower temperatures to improve the viscosity of glass. Glass with Al2O3 can reduce the tendency of glass precipitation and enhance chemical stability, improve the strength, increase the viscosity of glass. Its reference raw materials are usually accompanied by K2O or Na2O and SiO2 feldspar, can also use industrial alumina, etc. Cangzhou Tianchang Craft Glass Products Factory specializes in the production of various types of high borosilicate glass tubes

　　② alkali metal oxide raw materials: there are Na2O, K2O raw materials. Glass with Na2O and K2O components can reduce the melting temperature, reduce viscosity, but will make the chemical stability of the glass worse. Its cited raw materials are soda ash (Na2CO3) and potash (K2CO3).

　　③ alkaline earth metal oxide raw materials: CaO, MgO, BaO, ZnO, PbO raw materials. Glass with CaO and MgO can reduce the tendency of soda silica glass precipitation, enhance chemical stability, high temperature can reduce the viscosity of glass, promote glass melting and clarification, but the temperature decreases when the viscosity increases quickly, molding operation difficulties. The quoted raw materials are limestone (CaCO3) and rhodochrosite (MgCO3), or dolomite containing both CaO and MgO. The glass is often added BaO and ZnO to adjust the chemical stability and refractive index of the glass and other properties, the reference raw materials are often industrial ZnO and BaCO3, BaSO4 or Ba(NO3)2. glass with PbO can significantly improve the refractive index and dispersion, so that the glass absorbs short wavelength rays, at the same time, the specific gravity increases, the melting temperature is reduced, and the metal wettability is good. the reference raw materials for PbO are red and yellow dane or industrial lead nitrate.

　　In addition, broken glass is also a major raw material, often called clinker, which can be melted at a lower temperature to help the dissolution of the glass compound.

What are the advantages of modern pharmaceutical infusion bottles?

Modern medical technology is developing rapidly and has brought about a huge leap forward in many traditional treatment techniques and specialised tools. One of the more obvious conversions is that of the medicinal infusion bottle, which was traditionally made from laminated glass and was very inconvenient to transport and handle. However, modern science has improved the structure and raw material properties of medicinal infusion bottles, and infusion is becoming increasingly convenient. Let's explore what the benefits of modern medical device infusion bottles are, so let's find out what the advantages of modern medicinal infusion bottles are below!
