The PMMA plate) is widely used in, for example, lighting equipment, signboards, building materials, etc. because of its beauty, transparency and weather resistance. Also, because of its light weight and impact resistance,
It is also used in aquarium tanks. As a method of manufacturing the above PMMA plate, a so-called cell cast method has been used for a long time. That is, in a so-called cell that is assembled with a gasket sandwiched between the inner surfaces of a plurality of opposed flat plates, a monomer containing methyl methacrylate as a main component or a syrup thereof (hereinafter simply referred to as syrup) is filled, This is a method in which the syrup is polymerized to form a resin plate, and then the cells are disassembled, and the formed resin plate is taken out.
The flat plate is made of glass or metal. Hereinafter, an example of the method of manufacturing a PMMA plate by the cell casting method will be described in more detail with reference to FIG.
