It is reported that foreign professionals are through the following two ways to develop new glass.
The first is by changing the glass to change the content of some components in the material itself.
Recently created by Saint - Gobain AsolvexI type glass is 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% ( Exhalation rate of Al2O3 corresponds to 20 ml ampoule bottle under the condition of 125 ℃ 25 minutes) 。
the Al2O3 exhalation significantly reduced to obtain a new packing materials 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 glass cracking strength is relatively low, but the intensity of the internal fiber is very high. Glass is fragile, falls is because its surface is very small, Less than 1 micron) Defects, 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. 5 ~ 2 times, the existing research will lead to further improve the treatment effect, in the future, human is expected to produce almost no broken glass bottles.
some performance advantages make the glass on the surface of the glass with water features, this feature in some cases should be avoided. Such as in the field of medicinal, avoid the hydrophilic characteristics can make people easily all agents in the empty glass bottle. Saint - Gobain has carried out a project to solve the problem of research. With a lot of C - F hydrophobic molecules of single-layer coating of chemical bonds ( Thickness for molecular diameter size) , was carried out on the surface of glass processing, make water wetting Angle of 120 & deg; 。 Relevant personnel to plant leaf to experiment, to analyze the surface under the electron microscope, and the structure was simulated, taking spikes of nanometer size structure, to maintain transparency on the surface of the glass. It was found that water droplets ( Visible refractor) Seems to be suspended in the glass surface, this to develop not wet glass is undoubtedly a good news.
