mproved glass bottle material is expected to improve glass bottle performance

It is reported that foreign professionals are developing new types of glass through the following two approaches.The first is to change the material itself by changing the content of a component in the glass.The Asolvex type I glass recently created by Saint-Gobain was obtained by reducing the Al2O3 content in the glass bottle.The second is to coat the surface of the glass with a thin coating of auxiliary properties to improve its surface functional properties.In recent years,with the increasingly fierce competition in the packaging materials market,the demand for glass products in the industry has also become higher and higher.It is a general trend to improve glass production processes and develop new types of glass.
Asolvex glass is a new type I glass.Type I glass is borosilicate glass and has chemical resistance.The content of Al2O3 in the glass component of Asolvex is reduced by 50%compared to the ordinary type I glass,and the content of silicon is increased accordingly,which makes the precipitation of Al2O3 greatly reduced.With normal non-ionized water,even a 75%reduction in sodium gluconate solution(Al2O3 precipitation rate corresponds to a 20 ml injection vial held at 125°C for 25 minutes).
