Strip light cover is widely used in: optical lighting: it is used to manufacture large lampshades, protective glasses, left and right eyepiece tubes of optical instruments, etc., and it can also be widely used as transparent materials on aircraft. Electronics and appliances: polycarbonate is an excellent E (120 ℃) class insulating material, which is used to manufacture insulating connectors, coil frames, pipe sockets, insulating sleeves, telephone shells and parts, and battery shells of miner's lamps. It can also be used to make parts with high dimensional accuracy, such as optical disk, telephone, electronic computer, video recorder, telephone exchanger, signal relay and other communication equipment.
Polycarbonate thin film is also widely used as capacitor, insulating leather bag, audio tape, color video tape, etc. Mechanical equipment: used for manufacturing various gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, as well as some mechanical equipment shells, covers, frames and other parts.
Medical equipment: cups, cylinders, bottles, dental instruments, drug containers and surgical instruments that can be used for medical purposes, and even artificial organs such as artificial kidneys and lungs. Other aspects: used as hollow steel double wall panel and greenhouse glass in architecture; Used in textile industry as textile bobbin, textile machine bearing bush, etc; For daily use, it is used as milk bottles, tableware, toys and models.
In the molding process of PC strip light cover , moisture control and the selection of molding processing conditions are the two most important factors affecting the quality of molded products, which are described as follows:
Moisture control
PC plastics will break bonds, lower molecular weight and lower physical strength due to hydrolysis even when encountering very low moisture content. Therefore, the water content of polycarbonate shall be strictly controlled below 0.02% before molding to avoid the mechanical strength reduction of molded products or abnormal appearance of bubbles, crazes, etc.
on the surface. In order to avoid abnormal conditions caused by moisture, polycarbonate should be dried for more than three to five hours by a hot air dryer before processing, and the temperature should be set at 120 ℃, or the moisture should be treated by a desuperheating dryer, but the dehumidifying air should have a dew point of - 30 ℃ at the inlet of the funnel.
Key points for selection of extrusion molding machine
Clamping pressure:
Multiply the projected area of the finished product by 0.47 to 0.78 tons per square centimeter (or 3 to 5 tons per square inch).
