A New Journey for Fluorochemicals: Longxin Drying Elevates Post-Processing Efficiency of Fluoropolymer Materials
Jul 09, 2026
Spring arrives with thriving foliage and warbling birds, a season where long-term accumulation culminates in remarkable breakthroughs. At Longxin Intelligent’s pilot base for the engineering and industrialized production of micro & nano materials, spray drying tests on ultra-fine PVDF lithium-ion battery binder powder for a leading fluoropolymer client achieved full success. From process R&D to full-line commissioning, Longxin delivers comprehensive drying and purification solutions for fluoropolymer post-processing. This landmark milestone not only marks a new leap in Longxin’s technical prowess in high-end fluoromaterial equipment, but also signals a new dawn of domestic and intelligent manufacturing for the critical post-processing links of China’s fluoropolymer industry.
Blue Ocean Market Paired with Persistent Pain Points: Challenges in Fluoropolymer Post-Processing
Currently, the rapid expansion of global new energy, semiconductor, 5G communication and aerospace industries has generated unprecedented demand for high-performance fluoropolymer materials. Ranging from PVDF binders in lithium-ion batteries, perfluorosulfonic acid resin (PFSA) proton exchange membranes — the core component of hydrogen fuel cells, to corrosion-resistant and heat-resistant fluoroplastics such as PTFE and PFA, fluoropolymer macromolecules have become an indispensable cornerstone of strategic emerging industries. As application scenarios advance toward high-end segments, the market imposes increasingly stringent standards for material purity, particle size distribution, flowability and batch consistency.
Despite broad market prospects, fluoropolymer post-processing has long been plagued by severe challenges. Conventional drying and purification processes suffer from high energy consumption, difficult solvent recovery, severe particle agglomeration and excessive residual impurities. Especially when handling difficult materials like PVDF slurry and suspended PTFE powder, existing equipment fails to balance high throughput and premium quality, often resulting in unstable product performance or even scrapped batches due to cross-contamination. In addition, volatile organic solvents and wastewater generated during fluoromaterial production impose heavy compliance burdens on environmental protection. Breaking through these process bottlenecks to realize efficient, eco-friendly and intelligent post-processing has become a critical pain point restricting the high-quality development of the fluoropolymer sector.
Longxin Custom Solutions: Innovative Drying Technology Redefines Fluoropolymer Post-Processing Standards
To address industry-wide pain points, backed by profound technical reserves and sustained independent innovation, Longxin Drying has rolled out a series of tailor-made post-processing solutions exclusively for fluoropolymers, covering the full lifecycle from laboratory R&D to large-scale industrial mass production.
1. PVDF Slurry Airflow Spray Dryer: A Revolutionary Upgrade for Battery-Grade Binders
Meeting the extreme requirements of lithium battery-grade PVDF binders for uniform particle size, low residual solvent and superior dispersibility, Longxin’s PVDF slurry airflow spray dryer transforms former process bottlenecks into intelligent production lines.
① Equipped with proprietary airflow atomization technology, it precisely controls droplet size to produce powders with ideal sphericity and narrow particle size distribution after drying.
② Built-in intelligent temperature regulation optimizes the product’s electrochemical performance and batch consistency, delivering reliable material support for high-end power battery manufacturing.
2. Suspended PTFE Airflow Drying System: Eliminating Contamination and Agglomeration Bottlenecks
Due to its unique suspended particle properties, PTFE powder is highly prone to agglomeration, wall adhesion and external contamination in traditional drying workflows.
① Longxin’s suspended PTFE airflow drying system implements full-process optimization from feed pretreatment to final cooling and packaging.
② Its specially engineered gas-solid flow field maintains PTFE particles in a highly dispersed suspended state inside the drying pipeline, enabling instant heat and mass exchange to eliminate caking caused by local overheating.
③ The fully enclosed clean design and inline filtration system completely block foreign impurity intrusion, yielding ultra-high-purity PTFE powder ideal for semiconductors and high-end anti-corrosion applications.
3. PVDF & ETFE Flash Dryer: Intelligent Upgrade for Cost Reduction & Productivity Growth
For fluororubber and resin materials including PVDF and ETFE, Longxin’s intelligent flash dryer integrates advanced PLC control systems and online monitoring sensors to enable real-time drying process adjustment and automatic fault diagnosis.
① High-speed crushing units work in tandem with instant hot air contact to rapidly remove surface and internal moisture from materials, drastically boosting processing capacity.
② Flexible parameter settings accommodate feedstock with varying moisture content and viscosity, cutting energy and labor costs per unit output and enabling genuine cost and efficiency gains for fluororubber manufacturers.
4. PFSA Closed-Circuit Spray Dryer for Perfluorosulfonic Acid Resin: Empowering Large-Scale Hydrogen Energy Production
As the "heart" of hydrogen fuel cells, the production of perfluorosulfonic acid resin (PFSA) demands near-perfect standards for environmental cleanliness and solvent recovery rates.
① Longxin’s PFSA closed-circuit spray dryer is engineered for production scaling from laboratory trials to full industrialization.
② Operating under an inert gas-protected closed circulation loop, the system prevents material oxidation and deterioration while achieving zero organic solvent emissions and ultra-high solvent recovery rates.
This groundbreaking technology resolves safety and environmental hurdles in large-scale PFSA manufacturing, accelerating the commercialization of domestically produced proton exchange membrane materials.
5. High-Purity PFA Filter-Wash-Dry All-in-One Unit: A Breakthrough for Refining & Purification Workflows
Developed for high-performance fluoromaterials such as melt-processable PTFE (PFA), Longxin’s high-purity integrated filter-wash-dry unit consolidates multiple sequential processes within a single piece of equipment.
① Its specialized stirring structure and heating design ensure full material dispersion during washing and uniform heating during drying, thoroughly removing reaction byproducts and impurity ions.
② The sealed, dead-space-free construction meets the ultra-high purity criteria for electronic-grade and medical-grade PFA resin, establishing a new benchmark for fluoropolymer refining and purification processes.
