The glass in the disassembly of shopping mall glass is formed by melting silica and other chemicals together (the main raw materials for production are: soda ash, limestone, quartz). A continuous network structure is formed during melting, and a silicate non-metallic material that gradually increases in viscosity and hardens during cooling to cause crystallization. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O · CaO · 6SiO2, etc., the main component is silicate double salt, It is an amorphous solid with an irregular structure. Widely used in buildings, used to shield wind and light, and belongs to mixture. There are also colored glass mixed with oxides or salts of certain metals to develop color, and tempered glass produced by physical or chemical methods. Sometimes transparent plastics (such as polymethyl methacrylate) are also called plexiglass. The eaves glass used to shield the rain outside the mall can be seen everywhere, but in the prior art, the eaves glass is installed in a complicated manner. Due to the excessive number of fixed parts installed, the process of installation and disassembly is complicated, and it is not conducive to cleaning workers Of cleaning work.
