It is reported that foreign workers are through the following two ways to develop new type of glass. The first is by changing the glass to change the content of some components in the material itself. * * * almost AsolvexI type glass is created by Saint Gobain - by reducing the Al2O3 content in glass bottles. Second is coated on the glass surface has auxiliary performance of thin coating, to improve its surface features. In recent years, with the increasingly fierce market competition, packaging materials industry will become more and more high to the requirement of glass products, glass production process improvement, development of new glass is the trend of The Times.

Asolvex glass is a kind of new type I glass. Type I is borosilicate glass, with chemical resistance. Asolvex glass composition than the average content of Al2O3 in type I glass fell 50%, while the content of silicon increases accordingly, which greatly reduce the precipitation of Al2O3. Under the condition of normal non-ionizing water, even in the sodium gluconate solution decreased by 75% (Al2O3 exhalation rate corresponding to 20 ml ampoule bottle under the condition of 125 ℃ 25 minutes).

This kind of Al2O3 exhalation significantly reduced to obtain a new packaging material provides a possible, because this feature applies to trace metal elements sensitive products, such as enzyme or product does not contain preservatives and moderator. Huge potential application of this material, especially for blood products, nutrition, biological agents, and genetic engineering drugs.

In addition, the glass can use any kind of material, such as metal, semiconductor, polymer coating processing. Coating thickness ranging from 1 nm to 1 micron of the thin coating, can yet be regarded as a kind of relatively simple and cheap, and can effectively change the glass surface performance, especially change the cracking strength and wet resistance of good method.

Although the glass cracking strength is relatively low, but the intensity of the internal fiber is very high. Glass is fragile, falls is due to its surface defects are very small (less than 1 micron), extension at break came from these small defect. Can't completely avoid defects in production, but can reduce or part of this defect. Processing on glass surface, with a very thin layer of organic compounds containing silicon solution can achieve this purpose. So similar glass silicon molecules react with glass, can form a solid network, thus become a solid coating, adhesive on the glass surface, can effectively fill the surface cracks.
