Plastic granulation equipment is a key piece of equipment used to reprocess recycled plastic waste into recycled plastic pellets for the purpose of manufacturing plastic products again. The following are some suggestions for selecting raw materials and ensuring quality:
Raw Material Selection of Plastic Granulation Equipment
- Recycled plastics: Recycled plastics usually come from waste plastic products, by-products of the manufacturing process, or waste materials, such as discarded woven bags, plastic bags, plastic drums, etc. Recycled plastics may be of various types, so they need to be classified and sorted to ensure the purity and consistency of the raw material before processing in the extruder machine plastic.
- Mixing of raw materials: Sometimes an extruder machine plastic may need to handle a mixture of plastic raw materials. In this case, it is necessary to ensure that the types and proportions of plastics in the mixture are reasonable and that there is good compatibility between these plastics to avoid undesirable products.
Raw Material Quality Requirements
- Cleaning and drying: Recycled plastic scrap usually contains impurities, dust, or moisture that can affect the processing results of the plastic granulation equipment and the quality of the resulting recycled plastic pellets. It is therefore important that the feedstock is adequately cleaned and dried before being fed into the plastic pelletizer.
- Stability of raw materials: Recycled plastics may have undergone multiple uses and processing, leading to breakage and degradation of molecular chains. When selecting raw materials, it is necessary to ensure the stability of the raw materials to avoid the quality of recycled plastics decreasing due to decomposition products or other unstable factors.
- Plastic types and proportions: Ensure that the types and proportions of plastics used in the plastic granulation equipment are consistent with the equipment’s processing requirements. Too much or too little of a particular plastic may cause the plastic pelletizer to fail to operate properly or produce unstable recycled plastic pellets.
Strict Control of Processing Parameters
- Temperature control: During the extruder machine plastic process, the heating temperature of the plastic granulation equipment needs to be strictly controlled to ensure that the raw material can be fully melted and maintain proper fluidity. Excessively high or low temperatures may result in a deterioration in the quality of the recycled plastic pellets.
- Pressure control: The extrusion process in the plastic pelletizer requires precise pressure control to ensure that the raw material is uniformly pressurized in the extrusion screw and sufficiently expanded and cooled at the extrusion outlet to ensure uniformity of form and size of the recycled plastic pellets.
Conclusion
The above raw material selection and quality requirements will ensure that the plastic granulation equipment can process the recycled plastic waste efficiently and produce high-quality recycled plastic pellets.
