玻璃是由石英砂、长石、石灰石及纯碱等在高温下熔融后经拉制或压制而成。玻璃具有优异的光学性能,良好的物理、化学性能,对光线的透射、反射、折射及吸收能力是其他材料所无法比拟的。 玻璃作为重要的建筑材料,广泛应用于建筑物的门、窗、屋面、墙体、室内外装饰,作为采光、遮像、隔声、隔热和防护材料。 玻璃产品按生产工艺分为一次制品(如普通平板玻璃、浮法玻璃、压花玻璃、夹丝玻璃、彩色玻璃、空心玻璃砖等)和二次加工制品(如钢化玻璃、夹层玻璃、中空玻璃、镀膜玻璃、丝印玻璃、雕花玻璃、镭射玻璃);按性能分有普通玻璃(如普通平板玻璃、浮 Glass is made of quartz sand, feldspar, limestone, soda ash, etc., melted at a high temperature and then drawn or pressed. Glass has excellent optical properties, good physical and chemical properties, and its ability to transmit, reflect, refract, and absorb light is unmatched by other materials. As an important building material, glass is widely used in doors, windows, roofs, walls, interior and exterior decoration of buildings, as lighting, masking, sound insulation, heat insulation and protective materials. Glass products are divided into primary products (such as ordinary flat glass, float glass, embossed glass, wire glass, stained glass, hollow glass brick, etc.) and secondary processed products (such as tempered glass, laminated glass, hollow glass, etc.) according to the production process. Coated glass, screen printing glass, carved glass, laser glass); divided by ordinary glass (such as ordinary flat glass, floating
