PC plastic pellets have excellent impact resistance, high transparency, wide temperature range: -40 to 160, good precision forming properties, stable molding dimensions, ultra-high self-extinguishing performance, super weather resistance and good electrical insulation properties.

PC plastic pellets can not be exposed to hot water above 60 °C for a long time. When PC burns, pyrolysis gas will be emitted. The plastic will burn and burn, but it will not be ignited. It will be extinguished from the fire source, emitting a thin and thin phenol smell. The flame is yellow and shining. Light black, the temperature starts to soften at 140 °C, and melts at 220 °C, which can absorb infrared spectrum.

PC plastic pellets have good transparency and high impact resistance. They are widely used in four major industries: optical lighting, electronic appliances, mechanical equipment and medical equipment. The specific applications are as follows:

Optical illumination: It is used to manufacture large lampshades, protective glasses, left and right eyepieces of optical instruments, etc. It can also be widely used for transparent materials on airplanes.

Electronics: Polycarbonate is an excellent E (120 ° C) grade insulation material used in the manufacture of insulated connectors, coil frames, pipe sockets, bushings, telephone housings and parts, battery shells for miner's lamps, etc. It can also be used to make parts with high dimensional accuracy, such as optical discs, telephones, computers, video recorders, telephone switches, signal relays and other communication equipment. Polycarbonate thin touch is also widely used as a capacitor, an insulating bag, an audio tape, a color video tape, and the like.

Mechanical equipment: used to manufacture a variety of gears, racks, worm gears, worms, bearings, cams, bolts, levers, crankshafts, ratchets, as well as some mechanical parts such as shields, covers and frames.

Medical equipment: cups, cans, bottles and dental instruments, medicine containers and surgical instruments that can be used for medical purposes, and even artificial organs such as artificial kidneys and artificial lungs.

Although PC plastic pellets are so widely used in life, many plastic materials are catching up with PCs. If we want to continue to develop, we must continue to innovate in order to stand in the huge raw material market.

The development and development of Bulldozer Spare Parts and Loader Spare Parts types must meet the work adaptability of different working conditions, and must maintain the maximum component versatility (or interchangeability) with the basic model, which will bring extremes to the users. Great convenience. In order to facilitate the purchase of accessories, the manufacturer has retained the parts number of Komatsu Corporation of Japan, and only the parts designed by the company in the modification have been numbered by their own manufacturers.

The Crawler Bulldozer and Crawler Excavator is mainly composed of an engine, a transmission system, a working device, an electric part, a cab and a hood. Among them, mechanical and hydraulic transmission systems include hydraulic torque converters, coupling assemblies, planetary gear-type power shift transmissions, central transmissions, steering clutches and steering brakes, final drives and travel systems.


The power output mechanism drives the working pump, the variable speed torque hydraulic system variable speed pump and the steering brake hydraulic system steering pump in the hydraulic system of the working device by means of gear transmission and spline connection; the sprocket represents the final transmission mechanism of the secondary spur gear transmission (including left and right final drive assemblies); track shoes including track assemblies, trolley frames and suspension assembly systems.
