Glass containers processed on the basis of glass are widely used in the field of daily chemicals. They are popular among users because of their high transparency and good hand feeling. Different glass materials directly determine the grade of the product. For example, in the fragrance market, the main material of perfume bottles is crystal white glass, while the more common daily chemical glass in the market is mostly high white material.
1. Material definition
Name: Glass
Main ingredients: Na2O CaO 6SiO2
Glass is formed by melting silicon dioxide and other chemicals together (mainly produced from: soda ash, limestone, quartz). A silicate-based non-metallic material that forms a continuous network structure during melting, and gradually increases in viscosity and hardens during cooling to cause it to crystallize. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with irregular structure.
2. Material properties
Good perspective and light transmission performance, simple manufacturing process, free and changeable shape, high hardness, heat resistance, cleanness, easy cleaning, low tensile strength, and can be used repeatedly.
3. Material category
Glass is divided into ordinary white material, high white material, super white material, and crystal white material. Different material colors can directly affect the transparency and brittleness of glass products. The better the raw material is, the better the quality of glass products is. Color prices also vary. The most common plain white material glass bottles use a lot of recycled materials (commonly known as broken glass) in the production ingredients, and the formula price of high white material and crystal white material is far higher than that of ordinary white material. High white material glass needs to choose fine material and quartz sand with less impurities and high density, and crystal white material is basically processed with quartz stone as the main material and silica as the auxiliary material.
4. Manufacturing process
Using quartz sand, soda ash, feldspar and limestone as raw materials, some auxiliary materials need to be incorporated into the molding of glass products, including clarifiers, fluxes, opacifiers, colorants, decolorizers, oxidizing agents and reducing agents, etc., after mixing , High temperature melting, homogenization, processing and forming, and then annealing.
5. Processing method
The main processing methods of glass are various, including artificial blowing, mechanical blowing, extrusion molding, drawing and so on. Among them, the high-white material glass is basically produced by row machines in China, while most of the crystal white materials are produced by manual machines.
6. Application of cosmetic glass packaging materials
Glass containers for cosmetics are mainly made of high-white materials, and high-end products also use crystal white materials, such as perfume bottles. Glass is further processed to form containers such as cream bottles, essences, toners, and essential oil bottles.
7. Sustainable development
After the glass products are consumed by the market, they can be recycled and reprocessed, and then reused.
