Waste PVC bottle recycling machinery

Waste PVC bottle recycling machinery

The biggest difficulty in recycling PVC bottles is sorting, especially with PET. Both PET and PVC have densities of 1.3-1.35 g/cm3, which prevents them from being separated by density methods. However, the processing temperatures of the two of them are quite different. If the PVC processing temperature is set, the PET has not melted. If the PET processing temperature is set, PVC plastic has already been decomposed.

PVC bottles are widely used in beverages, foods, pesticides, etc. With the rise of PET materials in recent years, the use rate of PVC materials has decreased, especially in food and beverages, China has basically not used PVC beverage bottles. .

The biggest difficulty in recycling PVC bottles is separation, especially separation from PET (separation into an important part of the recycling line for PVC bottles). Both PET and PVC have densities of 1.3-1.35 g/cm3, which prevents them from being separated by density methods. However, the processing temperatures of the two of them are quite different. If the PVC processing temperature is set, the PET has not melted. If the PET processing temperature is set, PVC plastic has already been decomposed.

When PVC is processed, it is best to add additives such as stabilizers and lubricants to reduce the time of high temperature.

The quality of waste PVC bottle processing recycled materials is generally better, can be used on higher grade products, or add new materials to reproduce PVC bottles.
