As we all know, glass bottles are mainly used as packaging materials for food, oil, alcohol, beverages, condiments, cosmetics and liquid chemical products, etc., and have a wide range of uses. The main characteristics of glass bottles are: non-toxic, tasteless; transparent, beautiful, good barrier, airtight, abundant and common raw materials, low price of glass bottles, and can be used for multiple turnovers, glass bottles are more heat-resistant, pressure-resistant, resistant to The advantage of cleaning is that it can be sterilized at high temperature and stored at low temperature. The main raw materials of glass bottles are natural ore, quartz stone, caustic soda, limestone, etc. Glass bottles are highly transparent and corrosion-resistant, and will not change material properties in contact with most chemicals.
But glass bottles also have their shortcomings, such as heavy weight, high transportation and storage costs, impact resistance, and brittleness. Fragility is the biggest problem in the use of glass bottles, which limits the daily use of glass products. So, how to solve the fragile problem of glass bottles?
The appearance of glass fiber reinforced plastic solves the problem of fragile glass. FRP, that is, fiber-reinforced plastic, generally refers to the matrix of unsaturated polyester, epoxy resin and phenolic resin reinforced with glass fiber. Reinforced plastic with glass fiber or its products as reinforcing material is called glass fiber reinforced plastic, or glass fiber reinforced plastic. Due to the different types of resins used, it is known as polyester fiberglass, epoxy fiberglass and phenolic fiberglass. Light and hard, non-conductive, stable performance, high mechanical strength, less recycling, corrosion resistance. It can replace steel to manufacture machine parts and automobile, ship shells, etc.
Glass is hard but fragile, has good transparency, high temperature resistance, corrosion resistance and other properties; at the same time, steel is hard and not brittle, and also has the characteristics of high temperature resistance. So people began to think that if a material that has the hardness, high temperature resistance and corrosion resistance of glass, and the characteristics of steel as hard and unbreakable can be made, then this material will be very useful.
