The physical recycling treatment method of 1l sealed round pail for sale is relatively simple, mainly drying and granulation of the cleaned 1l sealed round pail for sale waste. 1l sealed round pail for sale's physical handling is closely linked to the sorting process. There are two main types of physical recovery methods:

1. Cut the waste 1l sealed round pail for sale into pieces, separate HDPE, aluminum, paper and adhesive from PET, and then wash, dry and granulate the PET fragments;

Second, the waste 1l sealed round pail for sale on non-PET bottle caps, seat bottom, labels and other impurities with mechanical separation, and then through washing, crushing, granulation. Recycled PET must not contain PVC impurities, otherwise it will affect the color of PET.

When the amount of PVC mixed in is small, it can be separated by artificial method on the conveyor belt, that is, PVC and 1l sealed round pail for sale produce different melting points in the stressed part, and the broken PET and PVC fragments pass through the conveyor belt equipped with heaters and temperature control. The PVC is melted and adhered to the conveyor belt so that it can be separated from the PET. The label on the beverage bottle can be removed after the bottle is broken by a combination of blower and cyclone separator.

The broken PET fragments are added vertically from the top of the separation tower, and the fragments form a countercurrent with the updraft. According to the difference in the specific gravity of PET and label fragments, the labels are extracted and the PET comes out from the bottom of the separator. In order to ensure the efficiency of label separation, more than two sets of separation devices can be used in production.

The washing of PET fragments is very important. Washing usually uses 80-100℃ hot water to soften or dissolve EVA adhesives or other types of adhesives affixed to labels and bases. In order to prevent the shed adhesives from adhering to PET fragments again, additives, such as alkali, emulsifier or other special chemicals, need to be added to the water.

Generally, the formula composition and content of the cleaning solution is determined by the factory according to the source and bonding characteristics of the waste bottle. The cleaning solution can filter out the impurities and be re-heated for recycling. The washing can be carried out in the special cleaning tank equipped with a stirrer.

PET fragments are usually reduced to 2% by centrifugal dewatering machines, and then dried by belt or tube dryers, so that the moisture content is reduced to 0.5%. The high-quality 1l sealed round pail for sale recycling system successfully developed by Krone, Germany, can process up to 15,000 tons of PET beverage bottles annually, and the processed PET raw materials can be directly made into other PET containers, greatly reducing the production cost.

1l sealed round pail for sale Recycling system uses chemical coating removal technology, using caustic soda as chemical coating removal agent to remove pollutants adhering to the surface of 1l sealed round pail for sale. Any kind of 1l sealed round pail for sale can be recycled. The recycled products processed by the technology can not only be directly mixed to make bottles, but also meet the requirements of purity and quality due to the low content of acetaldehyde and yellow pigment, which is especially suitable for the packaging of products in the food and beverage industry, and the cost is 20%-30% lower than that of general new materials.
