Alumina Ceramics:
Alumina ceramic polycarbonate occupies an extremely important position in this field due to its unique characteristics of high light transmittance, high refractive index, high impact resistance, dimensional stability and easy processing and molding. Optical lenses made of optical grade polycarbonate can be used not only for cameras, microscopes, telescopes and optical testing instruments, but also for film projector lenses, copier lenses, infrared auto-focusing projector lenses, laser beam printer lenses, and various Many office equipment and home appliances, such as prisms and polygon mirrors, have a very broad application market. Another important application field of polycarbonate in optical lenses is as a lens material for children's glasses, sunglasses and safety glasses, and adult glasses. The average annual growth rate of polycarbonate consumption in the world's optical industry has remained above 20%, showing great market vitality. With the rise of the information industry, optical discs made of optical grade polycarbonate, as a new generation of audio-visual information storage media, are developing rapidly at an extremely fast rate. Polycarbonate has become the main raw material of the world's optical disc manufacturing industry due to its excellent performance characteristics. The consumption of polycarbonate in the world's optical disc manufacturing industry has exceeded 20% of the overall consumption of polycarbonate, and its average annual growth rate has exceeded 10%. China’s CD production has grown rapidly. According to figures released by the State Press and Publication Administration, there were 748 CD production lines nationwide in 2002, which consumed about 80,000 tons of optical grade polycarbonate, all of which were imported. Therefore, the application prospect of polycarbonate in the field of optical disc manufacturing is extremely broad. It is used to manufacture large-scale lampshades, protective glasses, left and right eyepiece tubes of optical instruments, etc. It can also be widely used as transparent materials on airplanes. Polycarbonate is an excellent E (120°C) grade insulating material, used to manufacture insulating connectors, coil frames, tube sockets, insulating sleeves, telephone shells and parts, and battery shells for miner’s lamps. It can also be used to make parts with high dimensional accuracy, such as optical discs, telephones, electronic computers, video recorders, telephone switches, signal relays and other communication equipment. Polycarbonate film is also widely used as capacitors, insulating bags, audio tapes, color video tapes, etc.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
