Introduction of pharmaceutical glass, Jiyuan Yaohui glass small to present to you
Pharmaceutical glass refers to glass specifically used for pharmaceutical packaging, generally referring to glass bottles and jars and utensils. According to the glass material, it can be divided into soda lime glass and borosilicate glass. According to the manufacturing process, it can be divided into moulded bottles, control bottles and ampoules. Chemical properties are one of the most important criteria for measuring the quality of pharmaceutical glass, an important parameter of which is the coefficient of linear thermal expansion. Whether the drug will reflect with the glass in long-term storage. According to the coefficient of linear thermal expansion, pharmaceutical glass is classified accordingly. The international standard ISO 12775 - 1997 "Classification of normal mass-produced glass by composition and its test methods" divides pharmaceutical glass into three types.

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

Powder ampoules are used to dispense injectable powders or crystalline drugs. The neck of the bottle is thick or flared to facilitate the loading of the drug. The body of the bottle is as thick as the neck, and a groove is blown in the connection between the neck and the body, which can be sawed open when used and injected after dissolving in solvent. This kind of ampoule is inconvenient to use. In recent years, a kind of injection container has been developed which can contain both powder and solvent, the container is divided into two chambers, the lower compartment contains sterile drug powder, the upper compartment contains solvent, the middle is separated by a special septum, when using, the top plug is pressed down, the septum opens, the solvent flows into the lower compartment, the drug is dissolved and then used. This kind of container for injection is especially suitable for some drugs that are unstable in solution.

Although the primary task of glass enterprises should undoubtedly be to do a good job in business, to create economic benefits or material wealth, to promote social and economic development, and, if the glass enterprise enterprise lost the function of creating material wealth, it also lost the basic value of existence. However, a truly outstanding glass enterprise is definitely not just a "first in sales", "first in scale" or "first in profit" enterprise, it must have a strong sense of social responsibility. In fact, enterprises in the market economy are inextricably linked to society. Enterprises come from the society and will definitely return to the society, which is a kind of social-enterprise relationship under the new situation. The development and growth of an enterprise or its elimination from the market are to be taken up by society. More importantly, society is the survival environment for enterprises, without a good environment, it is also difficult for enterprises to survive. Therefore, from this perspective, glass enterprises should take the initiative to take up their social responsibility as well as their responsibility to their internal staff, so as to lay a solid foundation for their long-term development.
