Problems solved by technology

[0002] Polycarbonate is a thermoplastic resin with a carbonate bond structure in its main molecular chain. It has the advantages of light weight, high transparency, good impact resistance, heat resistance, cold resistance, stable size, high light transmittance, and easy processing and molding. It has been widely used as a material for optical lenses, lenses, etc., but compared with optical glass, polycarbonate has low surface hardness and poor wear resistance, and the lenses made of it are easily damaged during use, which seriously affects its use value
