Introduction to Plastic Water Tank

Waste plastic water tanks are mainly made of high-density polyethylene (HDPE), polypropylene (PP), and polyvinyl chloride (PVC): HDPE is widely used for water storage tanks due to its corrosion resistance, impact resistance, non toxicity, and recyclability (marked as “02”); PP is heat-resistant, lightweight, and suitable for small containers; PVC is resistant to chemical corrosion but contains chlorine. Recycling requires professional treatment.

Recycling process

The mechanical recycling process of waste plastic water tanks: Firstly, large crushing equipment is used to shred the water tank into small pieces, and then further refined into particles through secondary crushing, while initially separating metal components; Then thoroughly clean the fragments with hot water and cleaning agents, use density differences to separate plastic particles from light impurities, and remove residual metals through magnetic separation and eddy current separation; After cleaning, the plastic particles are melted at high temperature and finely filtered, and then cut into standard sized recycled plastic particles by a cutting mechanism; The entire process strictly detects the content of harmful substances to ensure that recycled plastics meet environmental standards. The final product can be widely used in the manufacturing of daily necessities such as water pipes and building materials, achieving efficient recycling.
