Extraction agent LD-7408
The Diaphragm White Oil Extractant is suitable for the white oil extraction process in the production of lithium battery separators and ultra-high molecular weight polyethylene (UHMWPE) fibers. It efficiently replaces traditional dichloromethane (DCM) as the extractant. Compared to conventional solvents, this product offers superior safety, environmental performance, and process compatibility. It helps enhance end-product quality, streamline production, and meet increasingly stringent environmental regulations.

  
Project background:
The existing wet process of lithium battery separators requires the use of a large amount of dichloromethane as a white oil extractant. Dichloromethane is toxic and harmful, volatile, and separation, recovery, and purification The equipment investment cost is high, and the recovery operation energy consumption is high. The characteristics make lithium battery separator Enterprises bear huge investment costs, environmental protection, safety, occupational health pressures ,And social responsibilities.

  
Project significance:
1: Reduce equipment fixed asset investment
2: Solve the problem of high volatility
3: Improve production efficiency
4: Solve the problem of high VOC occupational health
