B. used in automobile manufacturing. Polycarbonate has good impact resistance, thermal deformation resistance, weather resistance and high hardness, and is suitable for producing various parts of cars and light trucks, mainly focusing on lighting systems, dashboards, heating plates, defrosting devices and bumpers made of polycarbonate alloy.
C. used in the production of medical devices. Polycarbonate products can withstand steam, cleaning agents, heating and high-dose radiation disinfection without yellowing and physical properties degradation, so they are widely used in artificial kidney hemodialysis equipment and other medical equipment that need to be operated and disinfected repeatedly under transparent and intuitive conditions. For example, the production of high-pressure syringes, surgical masks, disposable dental instruments, blood separators and so on.
D. used in the aerospace field. In recent years, with the rapid development of aerospace technology, the requirements for components in aircraft and spacecraft are increasing, which makes the application of PC in this field increase day by day. According to statistics, a single Boeing aircraft uses 2,500 polycarbonate components, and a single aircraft consumes about 2 tons of polycarbonate. On the spacecraft, hundreds of different configurations of polycarbonate components reinforced by glass fibers and astronauts' protective equipment were used.
E. used in the field of packaging. In recent years, the new growth point in the field of packaging is various types of sterilized and reusable water storage bottles. Because polycarbonate products have the advantages of light weight, good impact resistance and transparency, no deformation and transparency when washed with hot water and corrosive solution, PC bottles have completely replaced glass bottles in some fields.
F. used in the field of electronic appliances. Polycarbonate is an excellent insulating material because it has good and constant electrical insulation in a wide range of temperature and humidity. At the same time, its good flame retardancy and dimensional stability make it form a broad application field in the electronic and electrical industry. Polycarbonate resin is mainly used to produce all kinds of food processing machinery, power tool shells, machine bodies, brackets, refrigerators, freezer drawers and vacuum cleaner parts. In addition, polycarbonate materials also show extremely high use value for important components in computers, video recorders and color TVs that require high precision.
G. used in the field of optical lenses. Polycarbonate occupies an extremely important position in this field because of 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 autofocus projector lenses, laser beam printer lenses, various prisms, polygon mirrors and other office equipment and household appliances, and its application market is extremely broad. Another important application field of polycarbonate in optical lenses is as lens material for children's glasses, sunglasses, safety glasses and adult glasses. In recent years, the average annual growth rate of polycarbonate consumption in the world glasses industry has remained above 20%, showing great market vitality.
H. basic materials of optical disks. In recent years, with the development of information industry, optical discs made of optical grade polycarbonate are developing rapidly as a new generation of audio-visual information storage media. Polycarbonate has become the main raw material of the world optical disc manufacturing industry because of its excellent performance characteristics.
