LDPE plastic recycling process
The scientific name of LDPE is low-pressure polyethylene, and packaging films in plastics are generally made of this material. For example, woven bag inner film, greenhouse film, food packaging film, etc., LDPE films are mostly transparent colors, of course, there are other colors such as blue, black, gray, etc. If you want to get a better recycling effect, you have to distinguish the color of the film material before the mechanical process, and you can't mix it up. There are four processes for LDPE plastic recycling, which are crushing and cleaning, drying, granulating, and pelletizing. The two processes of crushing and cleaning and crushing material drying are two very important steps in the recycling process, and they also have the greatest impact on the quality of finished materials. Two steps. Next, we will introduce these two steps in detail:
- Crushing and washing: The plastic is crushed and rinsed with a little water before this step will have a better effect. In the crushing and cleaning process, the cleaning and crushing of the crushed materials are equally important. The quality of the material to be judged is largely related to the cleanliness. This step is the first of the four steps and is also a very important step, so you must strictly follow the equipment Operate according to the operating plan given by the manufacturer. After the crushed material flows to the sink, it must be rolled again, so that the crushed material can be cleaned to a greater extent.
- Drying: Use the dewatering machine to spin off the crushed material. Strictly follow the manufacturer's instructions. Before each dewatering operation, check whether each part is normal. After the operation is completed, remember to turn off all power sources to prevent equipment parts Unnecessary wear and tear. The production line of our factory contains a dehydrator, which can quickly dehydrate, and the dehydration rate is as high as 90%.
STPLAS MACHINERY is this kind manufacturing to make plastic films to film scraps.
crusher washer drier and pelletizer the complete line which we can supply.
