Product introduction

Dual Rubber Roller Liquid Squeezing Unit To efficiently remove residual methylene chloride from wet-process lithium battery separators, we have developed a unique dual-roller liquid squeezing technology. The system consists of a liquid-squeezing bottom roller and a pressure roller:- The bottom roller has built-in heating to quickly dry residual liquid in the membrane.

- The pressure roller adopts an optimized force-bearing structure to ensure uniform pressure on the membrane surface, solving the problems of uneven liquid extrusion and difficult residue removal in traditional processes.

This technology significantly reduces energy consumption for subsequent solvent evaporation through efficient liquid squeezing, thereby cutting energy use in drying units. It improves production efficiency while achieving energy conservation and emission reduction. The liquid squeezing unit uses special fluororubber resistant to methylene chloride to avoid rubber swelling and extend service life. The roller surface can be treated with a corrosion-resistant coating to isolate the solvent from the rubber, further enhancing durability, facilitating cleaning/maintenance, and preventing membrane damage. This technology not only improves membrane quality but also optimizes the production process, becoming a key technological innovation in separator manufacturing.

Product introduction

Lithium Battery Separator Coating Rubber Rollers

During lithium battery separator coating, rubber rollers often face challenges such as uneven force distribution, chemical corrosion, and swelling, leading to excessive pressure on both sides, rapid edge wear, short service life, and frequent replacements that affect production efficiency. To address these issues, we introduce high-performance coating rubber rollers specifically designed for lithium battery separator coating.These rollers feature a dual-layer structure that optimizes force distribution on the rubber pressing surface, ensuring uniform pressure during coating and significantly reducing edge wear. The surface uses specialized rubber with excellent chemical resistance, effectively resisting corrosion and swelling from organic solvents like DMAC to greatly extend service life. Additionally, a chemical-resistant coating on the roller surface not only further isolates the solvent from the rubber to enhance durability but also has low surface energy to prevent adhesion of oligomers and other harmful substances, enabling easy cleaning and maintenance while improving coating quality and production efficiency.With their durable, stable, and efficient characteristics, lithium battery separator coating rubber rollers become a reliable choice in the coating process, safeguarding high-quality production for customers.
