Glass containers processed on the basis of glass are widely used in the field of daily chemical industry. Because of its high transparency and good handle, they are deeply loved by users. The quality of glass bottles directly determines the grade of products. For example, in the fragrance market, the main material of perfume bottles is crystal white glass, and the most common daily chemical glass in the market is high white material. Characteristics of glass products: good perspectivity, light transmittance, simple manufacturing process, free and variable modeling, high hardness, heat-resistant, clean, easy to clean, low tensile strength.




Cosmetics used for glass containers are mainly high white materials, and high-grade products also use crystal white materials, such as water bottles. Glass is formed through deep processing, cream, cream, essence, toner, essential oil bottle and so on.




The main processing methods of glass bottle are various, including manual blowing, mechanical blowing, extrusion molding, drawing, etc. Among them, the high white glass is basically produced by row and column machines in China, while the crystal white glass is mostly produced by manual machines.




Glass bottles are divided into ordinary white material, high white material and crystal white material. Different material colors can directly affect the transparency and brittleness of glass products. The better the raw materials are, the better the quality of glass products is, and the different material colors have different prices. The most common glass bottle with ordinary white material is used in the production of recycled materials (commonly known as broken glass). The formula price of high white material and crystal white material is far higher than that of ordinary white material. High whiteness glass needs to choose the fine material and quartz sand with less impurities and high density, while the crystal white material is basically made of quartz stone as the main material, silica as the auxiliary material, and then processed.




The glass bottle is made of quartz sand, soda ash, feldspar and limestone. Some auxiliary materials, including clarifiers, fluxes, opacifiers, colorants, decolorizers, oxidizers and reducers, need to be incorporated into the glass products for molding. After mixing, high-temperature melting and homogenization, it is processed and formed, and then annealed. After the glass products are consumed by the market, they can be recycled for further processing and then reused
