Description
Tempered glass can be used for windows and doors in high-rise buildings, glass curtain walls, interior partition glass, skylights, observation elevator passages, furniture, glass railings, etc. This dataset includes major raw materials, auxiliary materials, energy consumption, and atmospheric emissions from the production process; infrastructure such as manufacturing of production equipment and construction of factory buildings are not included within the system boundary of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The manufacturing process of tempered glass includes inspection, glass cutting, edge grinding, drilling, cleaning and drying, loading, heating, air cooling, unloading, inspection, and homogenization procedures.
Activity Description
The production process of tempered glass raw sheets includes inspection, glass cutting and blanking, edge grinding, drilling, cleaning and drying, loading, heating, air cooling, unloading, inspection, and homogenization.
Process Description
Tempered and semi-tempered glass are safety glasses in which the surface strength is increased several times by heating and rapid cooling treatment of plain glass. Tempered glass is widely used in building facades, interior decoration, modern furniture, and various industrial glass applications. The surface compressive stress of tempered glass exceeds 90 MPa, while that of semi-tempered glass ranges between 24 and 69 MPa.
