Polyvinyl chloride plastics vary in their shapes and sizes, and they can be processed in a variety of ways, including pressing, extrusion, injection, and coating. The particle size, fisheye, bulk density, purity, foreign matter, and porosity of the polyvinyl chloride resin all have an effect on the processability; the paste resin should consider the viscosity and gelation properties of the paste.
Polyvinyl chloride is an amorphous polymer with a small shrinkage. Before the powder is processed, it should be preheated to remove water, enhance the plasticizing effect and prevent air bubbles. Moreover, PVC is easily decomposed, especially in contact with steel and copper at high temperatures (decomposition temperature is 200 degrees). The molding temperature range is small, and the material temperature must be strictly controlled. When using a screw-type injection machine and a straight-through nozzle, the aperture should be large to prevent dead ends. The mold casting system should be coarse, the gate section should be large, the mold should be cooled, the mold temperature is 30-60 degrees, and the material temperature is 160-190.
1. The surface hardness and tensile strength of pipe are excellent, and the pipeline safety factor is high.
2. Good aging resistance, normal service life can be up to 50 years.
3. Excellent corrosion resistance of inorganic acid, alkali and salt, suitable for industrial sewage discharge and delivery.
4. The friction resistance coefficient is small, the water flow is smooth, it is not easy to clog, and the maintenance work is low.
