Dry Goods in The Injection Molding Industry: Analysis Of The Process Flow Of Six Recycled Plastics----ABS/PC/PVC

ABS plastic process

Most of ABS plastics come from small components on home appliances, various daily utensils and some mechanical equipment.

The actual production and processing steps of recycled ABS are as follows:

1. As far as ABS is concerned, there are more computer casings, TV casings, instrument panel casings, car control panels, and architectural decoration materials. Break these materials, and separate the electroplating process and spray color.

2. Organic chemical solution, stripping, stripping, but stripping and stripping need to be cautious, because there are some preparations of organic chemical solutions, use protective equipment and utensils, otherwise it will cause damage and other things.

3. Clean the tank to clean up, then dry it, color or put auxiliary materials, the purpose is to ensure the quality.

4. The special-purpose extruder is used for granulation, but the filter screen needs to be placed, but the filter screen is placed according to the regulations of the product.

PC regeneration polycarbonate (PC) process

Polycarbonate, amorphous plastics, engineering project plastics. Most of them come from textile accessories, car headlights, rear taillights, direction lights, sugar cubes to make mold shells, CDs, telecommunications equipment, photographic equipment, etc.

The actual production and processing steps of recycled PC are as follows:

1. Select the recycled PC first, there are fully transparent and not fully transparent, blue, red, green and black must be separated; there are also modified materials, such as most textile accessories are modified materials; such as CDs, lamp sockets are all Surface coating.

2. Cleaning of various PCs, stripping processes such as optical disc lamp sockets, etc., is also operated on the same basic principle as ABS. It is then dried, classified, and sent to an extruder for production.

3. Some PCs are pale yellow and can be produced in porcelain white; fully transparent ones are still fully transparent; other colors can be added with additives and raw material modifiers.

4. Special extruder is used for granulation, but PC itself is easy to be brittle, so it cannot be recycled several times, and granulation needs to be cautious and granulated and packaged.

Process flow of recycled polyethylene (PVC) high hardness

Most of the high hardness of PVC comes from building decoration materials, plastic steel windows and doors, electroplating process hard boards, plastic gate valves for pharmaceutical factories, sewer pipes, and building decoration materials.

The actual production and processing steps of recycled PVC high hardness are as follows:

1. Select the process first and separate each color. This kind of raw material is much higher than that of all three types: milky white, dark gray and gray-black, but it is not necessary to mix PP and PE.

2. To pulverizer to pulverize, but also to pulverize with water. Remove the pollution and clean it with water, and then dry it to avoid secondary pollution.

3. Put the seasoning on the mixer and stir. If it is a milky white material, add some additives, according to the promotion of modifiers, etc.

4. The special-purpose PVC extruder is the original factory for scraping and refrigerating bags.
