Our company's two extruders co extruded and successfully put into operation a two-layer composite winding production line, improving production efficiency, PPH winding material is a high-density polypropylene with excellent chemical stability and corrosion resistance. Therefore, PPH wrapped storage tanks have excellent chemical corrosion resistance and can store various chemical raw materials such as hydrochloric acid, sulfuric acid, nitric acid, etc. In the new energy industry, storing battery raw materials such as oxalic acid, sulfuric acid, and other harmful substances requires the use of PPH wrapped storage tanks. PPH wrapped storage tanks not only have good corrosion resistance, but also have good plasticity. Storage tanks can be manufactured in different shapes and capacities according to the needs of their usage, thus meeting different storage requirements.
