What is polycarbonate(PC)?
Polycarbonate is a common material in everyday life. Due to its colorless and transparent and excellent impact resistance, the common daily applications are CD/VCD, bottled water bottles, baby bottles, resin lenses, bulletproof glass, lampshade, animal cages, luggage, the helmet mask of the astronauts on the moon; Smartphone casing and so on.

PC chemical properties:
Polycarbonate, acid resistance, oil resistance, UV resistance, strong alkali resistance.

PC physical properties:
Polycarbonate is colorless and transparent, heat resistant, impact-resistant, flame retardant, and has good mechanical properties in common use temperature. Compared with the similar performance of polymethyl methacrylate, polycarbonate has good impact resistance, high refractive index and good processing performance. It does not need additives to have UL94 V-2 flame retardant performance. However, THE price of PMMA is relatively low and large devices can be produced by bulk polymerization. At present, with the expansion of the polycarbonate production scale, the price difference between polycarbonate and polymethyl methacrylate is narrowing day by day.

When polycarbonate burns, it will emit pyrolytic gas, and the plastic will burn and bubble, but it will not ignite. When it leaves the ignition source, it will be extinguished and give out a thin smell of phenol. The flame is yellow and light black, and begins to soften at 140℃ and melts at 220℃, which can absorb infrared spectrum.

Polycarbonate has poor wear resistance. Some polycarbonate devices used in wear-prone applications require special surface treatment.

Advantages of polycarbonate:
1. Mechanical properties: high strength and elastic coefficient, high impact strength, good fatigue resistance, good dimensional stability, little creep (little change under high-temperature conditions), high transparency and free dyeing;
2. Heat aging: wide range of temperature, enhanced UL temperature index up to 120~140℃ (outdoor long-term aging is also very good);
3. Solvent resistance: no stress cracking;
4. Water stability: it is easy to decompose when meeting water at high temperature (caution should be used in high temperature and high humidity environment);
5. Insulation performance: excellent (humidity, high temperature can also maintain stable electrical performance, is the manufacture of electronic, electrical parts of the ideal material);
6. Dielectric coefficient: 3.0-3.2;
7. Arc resistance: 120S;
8. Molding processability: injection molding or extrusion of ordinary equipment.

Polycarbonate PC Pulveriser Plastic Milling Machine Description:
Polycarbonate PC Plastic Pulveriser Machine of the PNMF series is available with disc diameter from 300 to 800 mm. These plastic pulverizer machines are high-speed, precision grinders for the processing of medium-hard, impact-resistant and friable materials. The material to be pulverized is introduced through the center of a vertically fixed grinding disc which is mounted concentrically with an identical high-speed rotating disc. Centrifugal force carries the material through the grinding area and the resulting powder is collected with a blower and cyclone system. Depending on the application the machines can be equipped with one-piece grinding discs or grinding segments.
The Polycarbonate PC plastic pulverizer machine is mainly composed of an electric motor, disc-type blade, feeding fan, vibrating sieve, dust removing system, etc.
According to the customer’s needs, you can choose some accessories, such as a converter, vacuum loader, screw loader, magnetic net, metal separator, chiller, pulse dust collector, metering and weighing packaging machine, etc.

Polycarbonate PC Pulveriser Plastic Milling Machine Technical Features:
1. The new disc design is of high quality, strong resistance and the life of this grinding disc is double the ordinary ones.
2. The newly designed professional bearings is with a high rotation rate. At the same time using only one drive motor, to ensure the efficient grinding crash, which greatly saves the time of machine operation and engineering control.
3. Easy installation and maintenance, just open the door to clean up.
4. The whole milling process is sealed, without dust leakage.
5. Full automatic design, automatically feeding, discharging and sorting.
6. Grinding gap adjustment is simple, just use the feeler gauge and adjusting bolts can be fine-tuning.
7. The mill uses the water and wind double cooling system, Prevent bearing and other parts from overheating.
8. Well-known brand accessories, such as SKF bearings and Siemens motors, can work for a long time, saving the trouble of changing accessories frequently.
9. With a wide range of optional accessories, professional solutions can be developed based on the customer’s budget and processing requirements.
