输送锂电正负极材料，三元材料，磷酸铁锂等，用什么材质比较好，防金属接触，禁铜锌，同得利推荐不锈钢304/316内衬四氟也是不错的选择。输送化工原料，粉体或颗粒状，有腐蚀性(如强酸、强碱、强氧化剂等)亦可选内衬四氟旋转阀，如物料有粘性，搭配侧快拆或滑杆式，可快速清洗叶轮，快速复位。

　　What is the best material for transporting lithium positive and negative electrode materials, ternary materials, lithium iron phosphate, etc.? It should prevent metal contact, prohibit copper and zinc, and Tongdeli recommends stainless steel 304/316 lined with PTFE as a good choice. Transporting chemical raw materials in powder or granular form, which are corrosive (such as strong acids, strong alkalis, strong oxidants, etc.), can also be equipped with a PTFE rotary valve lining. If the material is viscous, it can be paired with a side quick release or sliding rod type to quickly clean the impeller and reset it.

　　旋转阀内衬四氟(聚四氟乙烯 PTFE)的核心作用是‌利用氟塑料极 致化学惰性隔离腐蚀介质，同时凭借低摩擦系数保障旋转启闭灵活与密封可靠‌。‌‌

　　The core function of PTFE lining in rotary valves is to utilize the extreme chemical inertness of fluoroplastics to isolate corrosive media, while ensuring flexible opening and closing and reliable sealing with low friction coefficient. ‌‌

　　快拆滑杆式旋转阀内衬四氟核心功能：

　　1、极 致耐腐蚀隔离‌：PTFE几乎耐受所有强酸(如浓硫酸、氢氟酸、王水)、强碱及有机溶剂，解决金属材质易腐蚀失效难题 。

　　2、防金属接触：禁铜锌，内衬后形成物理屏障，阻断锂电池原料/化工物料腐蚀性介质与金属阀体/阀芯接触。

　　3、优异密封与防粘‌：表面张力极小具有不粘性，防止介质结晶或挂壁堵塞流道;配合弹性变形能力可实现紧密贴合，达到零泄漏标准(ANSI Class VI)，尤其适合频繁启闭场景 。

　　4、减摩润滑与扭矩降低‌：PTFE动静摩擦系数极低，显著减少旋转部件与阀座间的摩擦阻力，降低操作扭矩，防止卡涩，延长机械寿命 。

　　5、宽温适应性‌：可在 -196℃至 +200℃(部分工艺可达 250℃)范围内稳定工作，满足多数化工极端温度需求，同时保持化学稳定性 。‌‌

　　6、快速清洗维护‌：针对物料粘接，快拆清理，快速复位。采用滑杆式锁紧机构，可徒手或简单操作迅速打开阀体，转子易拆卸，清洗便捷，无卫生死角，符合食品、医药级 GMP 要求 。【电话/微信咨询：陈经理18068546632】

　　Quick release sliding rod rotary valve lined with PTFE core function:

　　1. Ultimate corrosion resistance isolation: PTFE can withstand almost all strong acids (such as concentrated sulfuric acid, hydrofluoric acid, aqua regia), strong alkalis, and organic solvents, solving the problem of metal material corrosion and failure.

　　2. Anti metal contact: Copper and zinc are prohibited, and a physical barrier is formed after lining to block the contact between corrosive media of lithium battery raw materials/chemical materials and metal valve bodies/cores.

　　3. Excellent sealing and anti sticking: With extremely low surface tension and non stick properties, it prevents medium crystallization or wall blockage of the flow channel; Combined with elastic deformation ability, it can achieve a tight fit and meet the zero leakage standard (ANSI Class VI), especially suitable for frequent opening and closing scenarios.

　　4. Friction reducing lubrication and torque reduction: PTFE has an extremely low coefficient of dynamic and static friction, significantly reducing the frictional resistance between rotating parts and valve seats, lowering operating torque, preventing jamming, and extending mechanical life.

　　5. Wide temperature adaptability: It can work stably within the range of -196 ℃ to+200 ℃ (some processes can reach 250 ℃), meeting the extreme temperature requirements of most chemical industries while maintaining chemical stability. ‌‌
