PVC光滑剂的分类:根据功用可分为PVC外光滑剂和PVC内光滑剂。外光滑剂与PVC的兼容性较差,简单从内部迁移到外表,构成光滑层界面,然后减少PVC熔体前粒子和PVC熔体和塑料之间的机械接触及外表之间的摩擦。内光滑剂富含极性基团,具有杰出的兼容性和PVC塑料、能够减少PVC塑料分子间作用力,降低熔体粘度,改进熔体流动性。
Classification of PVC smoothing agents: according to function, they can be divided into PVC external smoothing agent and PVC smoothing agent. The compatibility of the external smooth agent and PVC is poor. It simply migrates from the interior to the exterior, forms a smooth layer interface, and then reduces the mechanical contact between the PVC melt pre particles and the PVC melt and the plastic and the friction between the exterior. The internal smooth agent is rich in polar groups, with excellent compatibility and PVC plastics, which can reduce the intermolecular force of PVC plastics, reduce melt viscosity, and improve melt fluidity.
PVC光滑剂特色:有极性,能够前的树脂增塑树脂粒子构成的毛细管吸附、树脂粒子之间的链段间。光滑基因对树脂极性节点合型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵,然后削弱了树脂粒子与分子链段之间的作用力。树脂的分子链段彼此羁绊能够轻松地拓展,拓展到对方,浸透,树脂粒子之间的边界不见,以推进塑化。
PVC smooth agent characteristics: polarity, resin adsorption of resin plasticized resin and resin segments. The smooth gene pairs the polar nodes of the resin and then weakens the force between the resin particles and the molecular segments. The molecular chains of resin can be easily extended to each other, expand to each other, soak, and the boundaries between resin particles disappear, so as to promote plasticization
