Five Problems and Improving Methods of PVC Cable Material in Extrusion

First, Scorch phenomenon of PVC cable material when extrusioniPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Mold export smoke, the smell of strong stimulation and crackling; plastic surface with particles of burnt material; together there is a continuous bubble.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

1. Screw long-term use, the screw is not cleaned, accumulated scorched material out; split screw cleaning can be completely.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

2. Heating time is too long, plastic aging, scorch; shorten the heating time, check the heating system is a problem, and timely maintenance.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Second,Poor plasticization of PVC cable material when extrusioniPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Plastic surface with frog skin phenomenon, the surface of Ukraine, and a small crack or no plastic good small particles. There is a clear trace of the co-operation.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

1. The temperature is too low;iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

2. Granulation, the plastic mixed with plastic or difficult to plasticize the particles; mold sleeve may be appropriate with a little more to improve the pressure of the plastic mouth.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

3. Screw and traction speed is too fast, the plastic is not completely plasticized; appropriate slow down, extend the heating and plasticizing time, improve the plasticizing effect.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

4. material problems; refueling.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Third, The surface is not goodextrusion of PVC cable material when extrusioniPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

1. difficult to plasticize the resin in the absence of plastic extrusion, resulting in the surface of a small crystal point and particles, distributed around the surface; should be appropriate to improve the temperature or reduce the traction line speed and screw speed.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

2. When mixed with impurities, the surface of impurities pimple; feeding should be to prevent impurities mixed into the impurities should be found immediately into the head, the screw memory glue net.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

3. Die sets of wire diameter surface is not smooth or no gap, or plastic decomposition of the material deposited in the mold mouth, so that the surface traces; mold should carefully check the surface diameter is smooth, appropriate to reduce the die temperature, found The deposit should be removed immediately at the module.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

4. Cable core is too heavy, the line tension is small, and the cooling is not good, the plastic surface is easy to wrinkle; the former should increase the tension, which should reduce the traction wire speed, to ensure the cooling time.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Four, Uneven thickness and bamboo shape of PVC cable material when extrusioniPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

How to improve?iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Often check the traction, screw, and retractable tension device or speed, timely adjustment; optional mold to be appropriate to prevent the reverse; often monitor the change in diameter.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

Fifth, Stomata and bubbles of PVC cable material when extrusioniPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

1. Temperature control caused by the local high; found should be timely adjustment and strict control of temperature.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

2. Plastic damp or water caused by the discovery should be promptly halted side by side the net tide material.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

3. should increase the drying device; material drying and then use.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri

4. Wire core should be preheated.iPZPVC Cable,PVC insulated Power Cables,Flexible Wire,Concentri
