The new modified "glass" shows its strength in the packaging industry

for a long time, glass, as a good packaging material, has been widely used in packaging

but in recent years, with the increasingly fierce competition in the packaging material market, common faults: the sensitivity of the dial pointer is poor, and the industry has higher and higher requirements for glass products. It is a general trend to improve the glass production process and develop new types of glass

it is reported that foreign professionals are developing new glasses through the following two ways. The first is to change the material itself by changing the content of a certain component in the glass. Recently, the asolvexi glass created by Saint Gobain was obtained by reducing the content of Al2O3 in glass bottles. Secondly, the glass surface is coated with a thin coating with auxiliary properties to improve its surface functional properties

asolvex glass is a new type I glass. Type I glass is borosilicate glass with chemical resistance. The content of Al2O3 in asolvex glass is 50% lower than that of ordinary type I glass, while the content of silicon increases accordingly, which greatly reduces the precipitation of Al2O3. Under normal non ionized water conditions, it is even reduced by 75% in sodium gluconate solution (the precipitation rate of Al2O3 corresponds to the 20 ml injection bottle being maintained at 125 ℃ for 25 minutes)

this significant reduction in Al2O3 precipitation makes it possible to obtain new packaging materials, because this feature is applicable to products sensitive to trace metal elements, such as enzymes or products without preservatives and moderators. This material has great application potential, especially for blood products, nutrients, biological agents and genetic engineering drugs

in addition, glass can be coated with any material, such as metal, semiconductor, polymer, etc. Coating a thin coating with a thickness ranging from 1mackiewicz to 1 micron is a relatively simple and cheap method, which can formulate a targeted inspection plan according to the diagnostic results, and can effectively change the surface properties of the glass, especially its crack strength and moisture resistance

although the crack strength of glass is relatively low, its internal fiber strength is very high. The reason why the glass is fragile when falling is that there are very small (less than 1 micron) defects on its surface, and the fracture extends from these small defects. Defects cannot be completely avoided in production, but they can be reduced or partially reduced. This can be achieved by treating the surface of the glass and coating it with a very thin layer of silicon containing organic compound solution. Therefore, silicon molecules similar to glass react with glass to form a solid complex, which becomes a solid coating, adheres to the glass surface, and can effectively fill surface cracks

relevant tests showed that the crack resistance of these glass bottles increased by 1.5 ~ 2 times after treatment with silicone containing organic compounds, Existing research companies have always "Advanced technology will further improve these treatment effects. In the future, mankind is expected to produce almost unbreakable glass bottles and cans.

some performance advantages of the glass surface make the glass have hydrophilic properties, which should be avoided in some cases. For example, in the pharmaceutical field, avoiding its hydrophilic properties can make it easy for people to empty all the drugs in the glass bottles. Saint Gobain has carried out a research project to solve this problem Row. The surface of the glass is treated with a single layer of hydrophobic molecules with many C-F chemical bonds (the thickness is the molecular diameter), so that the wetting angle of water reaches 120 °

the relevant personnel carried out experiments on plant leaves, analyzed their surfaces under the electron microscope, and simulated this structure. They adopted the nanoscale spike structure to retain the transparency of the glass surface. It is found that water droplets (visible refractors) seem to be suspended on the glass surface, which is undoubtedly good news for the development of non wettable glass
