| Aquivion® P98-SO2F是磺酰氟化物（-so2f）形式的全氟化颗粒，其当量（ew）为980 g/eq。该材料基于Solvay生产的四氟乙烯（tfe）和磺酰氟化物乙烯基醚（sfve）f2c=cf-o-cf2cf2-so2f的独特短侧链共聚物。Aquivion® P98-SO2F树脂可以很容易地熔化挤压成各种形状。挤出机应配备一个标准的三区计量螺杆，没有屏障或混合元件。最佳温度设置将取决于设备的配置，但一般在200至300°C之间。可选地，模制品中的功能组随后在浴槽或湿工作台中水解，加热的碱（NaOH、KOH等）反应可能需要几分钟或几小时，具体取决于厚度和条件。Aquivion P87S-SO2F可以直接水解，可以完全水解，也可以只在其外表面水解。这将使磺酸/磺酰盐基团在离子交换操作或作为酸催化剂时具有功能活性。与其他含氟聚合物一样，含水层PFSA颗粒在熔融物中具有腐蚀性；因此，所有与熔融物长期接触的零件均应采用耐腐蚀材料制成，如哈氏合金、铬镍铁合金、蒙乃尔合金或xaloy。不建议使用镀铬或镀镍，因为它们通常只足以进行短暂的加工试验。有关详细信息，请访问aquivion.com。 Aquivion® P98-SO2F are perfluorinated pellets in the sulfonyl fluoride (-SO2F) form that exhibit an Equivalent Weight (EW) of 980 g/eq. This material is based on the unique Short Side Chain copolymer of Tetrafluoroethylene (TFE) and Sulfonyl Fluoride Vinyl Ether (SFVE) F2C=CF-O-CF2CF2-SO2F produced by Solvay. Aquivion® P98-SO2F resin can be easily melt extruded into a variety of shapes. The extruder should be equipped with a standard three-zone metering screw devoid of barrier or mixing elements. Optimum temperature settings will depend on the configuration of the equipment, but generally range from 200 to 300°C. Optionally, functional groups in the molded part are then hydrolyzed in baths or wet benches with a heated base (NaOH, KOH etc) reaction which may take minutes or hours, depending on thickness and conditions. Aquivion® P87S-SO2F can be directly hydrolyzed as described, either completely or only on their outer surface. This will enable functional activity of the sulfonic acid / sulfonyl salt groups for ion-exchange operations or as an acid catalyst. Like other fluoropolymers, Aquivion PFSA pellets are corrosive in the melt; therefore, all parts having prolonged contact with the melt should be made with corrosion-resistant materials such as Hastelloy®, Inconel®, Monel® or Xaloy®. Chrome or nickel plating is not recommended since they are typically only sufficient for brief processing tests. Please visit Aquivion.com for more information. |
