In the process of producing products with double-screw extruders, not only should the quality of the products be guaranteed by adjusting the machine, but also the safety of the operators should be given enough attention during the process of adjusting the machine, so how should we be in the process of running the machine? What about security issues? We introduce it to you in the article. In addition, in the article, we also analyzed the factors that affect the production of double-screw extruders. We hope that through the introduction of these two aspects, we will have a more comprehensive understanding of double-screw extruders.
1. The double-screw extruder equipment is driven by electricity, so we must pay attention to the safety of electricity use to prevent potential safety hazards such as electric shock and circuit fire.
2. Whether it is injection molding, extrusion, blow molding or curing of thermosetting plastics, a certain temperature is required during processing to enable the material to flow, and care must be taken to avoid burns during the molding operation.
3. The double-screw extruder usually includes mechanical parts such as motor, transmission box, screw, hydraulic components, etc. If improper operation may cause serious mechanical damage.
4. When the double-screw extruder is working, some materials are easily decomposed in the thermal processing process, or the melt contacts with air at high temperature to produce an exothermic oxidation reaction, which in turn leads to spontaneous combustion.
1. Selection of raw materials
In the production process of dual-screw extruder, the selection of raw materials is very important. It is not only required that the properties of the raw materials meet the use requirements of the products, but also the processing properties of the raw materials must meet the technological requirements of the dual-screw extruder. Generally, hollow grade resins are selected.
2. Temperature control
In the process of extruding the parison, the temperature control of the dual-screw extruder is very important. The choice of extrusion temperature depends on the properties of the resin. No matter whether the extrusion temperature is high or low, the quality of the product will be greatly defective.
3. The size and quality of the die
The die is the main device that determines the size and shape of the parison, so the inner surface of the die is required to be smooth and the surface roughness is low to facilitate the production of parisons with smooth surfaces.
