PVC Sheet Conical Twin Screw Barrel

Product Feature And Application

1. Due to the thin thickness and heat-sensitive nature of PVC Sheet Conical Twin Screw Barrel, Nanhai Ya's conical twin-screw has a deep groove design in the feeding section to enhance the rapid transportation of materials.

2. The efficient exhaust design ensures that the moisture contained in the PVC dry-mixed material, as well as the low-molecular volatile substances mixed in the air, are all removed during the extrusion process. The PVC sheet conical twin-screw of Nanhaiya specially adds additional reserved exhaust holes to prevent the original exhaust holes from getting clogged.

3. The surface of the twin conical screw is sprayed or coated with tungsten carbide (WC), nickel-based alloys, etc.The service life can be increased by 3 to 8 times.As the content of calcium carbonate and titanium dioxide increases, the wear resistance of the screw also needs to be further enhanced.

4. PVC sheet materials are mainly used in the production of artificial leather, films, wire sheaths, water supply pipes, household pipes, house wall panels, commercial machine casings, electronic product packaging, medical devices, food packaging and other plastic soft products. They can also be used to produce sheet materials, doors, windows, valves and other plastic hard products.

Production Details

1.Counter-rotating conical twin screws,The conveying efficiency is high, the heat generated by shearing is relatively controllable, and the mixing effect is excellent. It is particularly suitable for PVC sheet materials that are sensitive to heat.

2.Accurately calculate the compression ratio of the PVC sheet conical twin-screw.Ensure that the materials are fully compacted, melted and homogenized.

3.Precisely control the gap between the screw and the barrel. At the top of the screw and inside the barrel, tungsten alloy will be sprayed to maintain the stability of the gap size.
