As an important material widely used in many fields such as construction, automobiles, electronics, and daily consumer goods, glass has many types and different properties. In the field of foreign trade, understanding the classification and characteristics of glass is of great significance for expanding the market and meeting customer needs.
Glass can usually be classified according to its composition, production process and use. According to its composition, glass can be divided into silicate glass, borate glass, phosphate glass, etc. Among them, silicate glass is the most common one, mainly made of raw materials such as quartz sand, soda ash and limestone, with good transparency and chemical stability, and is widely used in construction and daily glass products.
According to the production process, glass can be divided into float glass, rolled glass, blown glass, etc. Float glass is made by floating molten glass on the surface of metal liquid, with a smooth surface, and is the main raw material for construction and automotive glass. Rolled glass is pressed by a calender at high temperature, has excellent mechanical strength and heat resistance, and is often used in the field of solar photovoltaics.
According to its use, glass can be divided into architectural glass, daily glass, optical glass, electronic glass, etc. Architectural glass includes flat glass, safety glass and energy-saving glass, which are used for doors, windows, curtain walls and partitions of buildings. Daily glass refers to daily necessities such as tableware and vases. Optical glass is used to manufacture optical instruments such as lenses and prisms. Electronic glass is used to manufacture electronic display screens and semiconductor devices.
In recent years, with the advancement of science and technology and the improvement of environmental awareness, special glass such as low-emissivity glass, fireproof glass and self-cleaning glass have gradually become popular products in the foreign trade market. These glasses not only have excellent performance, but also meet the requirements of sustainable development and are widely welcomed by the international market.
Understanding these glass classifications and their characteristics will help foreign trade companies grasp market demand more accurately and provide customers with the most suitable products and services.
