high temperature EVA waste scrap recycling equipment and process
1, high temperature EVA waste scrap recycling equipment, process
High-temperature EVA waste scrap recycling equipment is mainly used to deal with waste materials such as waste EVA scrap, through processing and recycling into reusable production raw materials. The main process includes the following steps: 1. cutting: cutting raw materials scrap material, broken into small particles. 2. Feeding: add the cut small granular raw materials to the rubber recycling machine, and control the appropriate processing temperature, pressure and time. 3. Mixing: After heating and mixing, the raw materials can be melted and fused. 4. Extrusion: The melted material is processed and shaped by the extruder to form a sheet or strip of recycled material. 5. Water washing and screening: water washing and screening of recycled materials to remove impurities and residues. 6. Drying: drying the recycled material after screening to reduce its water content to a suitable range. Through the above process, high-temperature EVA waste scrap can be effectively recycled and utilized, which is not only conducive to environmental protection, but also can reduce production costs and resource consumption.
2, which granulator is used with single screw rod or double screw rod
Granulator is a kind of equipment that pressurizes powdery or granular materials into solid particles. Common granulators include single screw rod granulators and double screw rod granulators. Among them, the single screw rod granulator has only one compaction rod, which is often used in small batch production or experimental production, while the double screw rod granulator has two compaction rods, which is often used in mass production or industrial production. Therefore, whether the granulator uses a single-screw rod or a double-screw rod machine needs to be comprehensively considered according to the scale, process characteristics, raw material properties and other factors required for production. Generally speaking, the single-screw rod granulator is suitable for small-scale or experimental production, while the double-screw rod granulator is suitable for large-scale industrial production.
3, its granulation temperature
granulation temperature is an important process parameter in the granulation process, which is related to the nature of raw materials, processing technology, equipment characteristics and other factors. The granulation temperature of different granulator and processing technology will also be different. In general, the granulation temperature should be controlled below the melting point or denaturation temperature of the raw material to avoid changes in the structure and properties of the raw material, which will affect the subsequent processing and use. If the granulation temperature is too high, it may cause problems such as thermal denaturation or oxidative degradation of the material, thereby affecting product quality. In the specific selection of the granulator and the development of processing technology, it is necessary to consider a number of factors, such as the characteristics and requirements of raw materials, equipment performance, processing technology, etc., to determine the appropriate granulator model and processing parameters. Generally speaking, the granulation temperature is controlled by adjusting the processing parameters to achieve the best granulation effect and product quality.
4, the use of regenerated high temperature EvA particles
Recycled high-temperature EvA particles are recycled plastic particles, usually made of waste polyvinyl alcohol ester (PVA), and made by high-temperature reprocessing. Because of its special physical and chemical properties, recycled high-temperature EvA particles are widely used in the following fields: 1. Packaging industry: recycled high-temperature EvA particles have good transparency, flexibility and tear resistance, and can be used to produce plastic bags, plastic wrap, Foam boxes and other packaging materials. 2. Automotive industry: Recycled high-temperature EvA particles have high impact resistance and wear resistance, and can be used to produce automotive interior parts, body parts, etc. 3. Electronics industry: Regenerated high-temperature EvA particles have excellent insulation properties and high temperature resistance, and can be used to produce wire and cable insulation layers, electronic components, etc. 4. Medical industry: Regenerated high-temperature EvA particles are non-toxic and odorless to the human body, have good corrosion resistance and high temperature resistance, and can be used in the production of medical equipment, surgical equipment, etc. It should be noted that although recycled high-temperature EvA particles have the environmental advantages of recycling and have gradually become an important part of the plastic material market, their use must be strictly in accordance with corresponding standards and specifications to ensure product quality and human health. safety.
