The SJSZ series conical twin-screw extruder is a professional equipment suitable for various PVC powder base molding. It is equipped with different molds and auxiliary machines and can produce various PVC plastic pipes.

The barrel is heated by a cast aluminum heater ring and cooled by an air cooling system. It has the characteristics of fast and uniform heat transfer, easy operation and maintenance.

The screw core adopts an automatic circulation cooling adjustment system to improve efficiency. According to different user formulas, a screw with a reasonable structure can be configured to achieve a good plasticizing state and logistics quality.

Advantages and characteristics of PVC pipes:

1. Light weight, convenient handling and loading and unloading: PVC pipes are very light, easy to handle and construct, and can save labor.

2. Excellent chemical resistance: PVC pipes have excellent acid resistance, alkali resistance, and corrosion resistance, which are very suitable for use in the chemical industry.

3. Small fluid resistance: The wall of the PVC pipe is smooth, with small resistance to the fluid. Its roughness coefficient is only 0.009, which is lower than other pipes. At the same flow rate, the pipe diameter can be reduced.

4. High mechanical strength: PVC pipes have excellent water pressure resistance, external pressure resistance, impact resistance, etc., and are suitable for piping projects under various conditions.

5. Good electrical insulation: PVC pipes have excellent electrical insulation and are suitable for conduits for wires and cables, and wire piping in buildings.

6. No impact on water quality: PVC pipes have been proven by dissolution tests to have no impact on water quality, and are currently the best pipe material for tap water piping.
