How to solve the fragile problem of glass bottles
As we all know, as packaging materials, glass bottles are mainly used for food, oil, wine, beverages, condiments, cosmetics and liquid chemical products, etc., with a wide range of uses. The main characteristics of glass bottles are: non-toxic and tasteless; transparent, beautiful, good barrier properties, airtight, abundant raw materials, low price of glass bottles, and can be used in multiple cycles, glass bottles are more heat-resistant, pressure-resistant and resistant The advantages of cleaning are high temperature sterilization and low temperature storage. The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone and so on. The glass bottle has a high degree of transparency and corrosion resistance, and the material properties will not change in contact with most chemicals.
However, glass bottles also have their disadvantages, such as large weight, high transportation and storage costs, impact resistance, and fragility. Fragility is the biggest problem in the use of glass bottles, which makes glass products subject to great limitations in daily use. So, how to solve the fragile problem of glass bottles?
The emergence of FRP solved the problem of fragile glass. FRP, namely fiber reinforced plastic, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics that use glass fiber or its products as reinforcing materials are called glass fiber reinforced plastics, or glass fiber reinforced plastics. Due to the different types of resins used, it is called polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. Lightweight and hard, non-conductive, stable performance, high mechanical strength, less recycling and corrosion resistance. It can replace steel to manufacture machine parts, automobile and ship shells, etc.
Glass is hard but fragile, has good transparency, high temperature resistance, and corrosion resistance. At the same time, steel is hard and not fragile, and it also has the characteristics of high temperature resistance. So people began to think that if they could make a kind of glass that not only has the properties of glass hardness, high temperature resistance, and corrosion resistance, but also has the characteristics of being hard and unbreakable like steel, then this material will be of great use.
