What is the process flow of recycled polyvinyl chloride (PVC) hard materials for recycled materials GRS? PVC hard materials are mostly from building materials, plastic steel doors and windows, electroplating hard plates, plastic valves in chemical plants, sewer pipes, decorative materials, etc.

  Recycled material GRSWhat is the process flow of recycled polypropylene (PP)? PP mostly comes from daily necessities, such as plastic boxes, foot basins, buckets, rice baskets, plastic chairs, stools, woven bags and other woven fabrics and packing belts. First, separate the colors of various materials, because the separation will be convenient for users and the price can be high. 2. Crush and wash, put the remaining water in the dryer for drying, and then dry and bagged. Mix with a blender and add some pigments and additives. 3. The granulation should use a special plastic machine, but the granulation temperature should not be too high, it is easy to be brittle, and the temperature must be paid attention. 4. Water-cooled granulation should be standard 3X4mm, otherwise the appearance of the best material will not look good and standard.

What is the process flow of recycled polyvinyl chloride (PVC) hard materials for recycled materials GRS? PVC hard materials are mostly from building materials, plastic steel doors and windows, electroplating hard plates, plastic valves in chemical plants, sewer pipes, decorative materials, etc.

1. First select the process and separation color. These materials can be divided into white, gray and black, but do not mix PP and PE together. 2. Crush with a crusher or with water. Remove pollution, wash with water, and then dry to prevent secondary pollution. 3. Ingredients and stirs on the blender. If it is a white material, add some colorants and additives if necessary. 4. Special PVC extruder is used for scraping, cooling, bagging and labeling.

  Recycled material GRSABS plastic, mostly from electrical products, a variety of daily necessities and some small mechanical parts.

1. For ABS, the computer shell, TV shell, instrument shell, car panel, decorative materials should be separated, especially plating and paint color. 2. Chemical treatment, deplating and paint stripping, but deplating and paint stripping need to be carried out carefully, because the chemical solution has a certain ratio, so use protective equipment and containers, otherwise it will cause injuries and other incidents. 3. Wash the tank, then dry, color matching or add accessories to improve the quality. 4. Use a special extruder for granulation, but you need to place a filter screen, but the placement of the filter screen should be based on product requirements. 5. Granulation includes cold water granulation or air cooling granulation. The granulation standard is 3x 4mm, followed by packaging labeling.

What is the process flow of recycled low-density polyethylene (LDPE) for recycled GRS? LDPE, the scientific name of high-pressure polyethylene, refers to plastic packaging film. Such as: woven bag lining film, food packaging film, daily necessities packaging film, greenhouse film, etc. These films are mostly natural colors, but also light blue and black. It is recommended to separate color samples before recycling. You can't put low pressure film and PP film together, and you can't put OPP and PVC film in. The recycling of LDPE is the process of recycling LDPE, and the whole process of recycling LDPE has four main processes.

Recycled material GRS: The first step is the crushing process. The effect of crushing and washing is better, because some good high-pressure films can be blown again as long as they are kept clean enough without adding new materials. Therefore, pay attention to cleaning during the crushing process. When the crushed material flows to the water tank, it is recommended to roll it again to further flush the cleaning point.

The second step is the drying process. Generally, the excess water is dried by a dryer, and then dried if possible, which can save electricity and improve quality. Of course, attention should be paid to prevent secondary pollution of materials during the drying process.

Recycled material GRS: The third step is the granulation process. Pellets made by special extruders have two basic uses: re-blown film and injection molding. The material from the 60-80 mesh filter can be blown again; the material filtered by the 40-60 mesh filter can meet the quality requirements of injection molding. Generally speaking, the high-pressure material is blown again, and the natural color is almost blown black film and garbage bags, and the price is lower after injection molding.

  Recycled material GRS: The fourth step is the granulation process, usually cold water granulation. In this process, we must pay attention to distinguish between labels, one blow molding and one injection molding, so as not to make mistakes. In addition, the packaging bag for blow molding needs to be lined with an outer bag to avoid secondary pollution.
