| 阳离子抗静电剂 Cationic antistatic agent 通常是些长链的烷基季铵、磷或鏻盐，以氯化物作平衡离子。它们在极性基质中，如硬质聚氯乙烯和苯乙烯类聚合物中效果很好，但对其热稳定性有不良影响。这类抗静电剂通常不得用于与食物接触的物品中；而且抗静电效果仅为乙氧基化胺类之类内用抗静电剂的1/5到1/10。 Usually long-chain alkyl quaternary ammonium, phosphorus or phosphonium salts, with chloride as equilibrium ion. They have good effect in polar matrix, such as UPVC and styrene polymer, but have bad effect on their thermal stability. This type of antistatic agent shall not be used in articles in contact with food; moreover, its antistatic effect is only 1 / 5 to 1 / 10 of that of internal antistatic agents such as ethoxylated amines. 阴离子抗静电剂 Anionic antistatic agent 通常是些烷基磺酸、磷酸或二硫代氨基甲酸的碱金属盐，也是主要用于聚氯乙烯和苯乙烯类树脂中；它们在聚烯烃类树脂中的应用效果与阳离子抗静电剂相似。在井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具 阴离子抗静电剂中，烷基磺酸钠已广泛应用于苯乙烯系树脂、聚氯乙烯、聚对苯二甲酸乙二醇酯和聚碳酸酯中。 They are usually alkali metal salts of alkylsulfonic acid, phosphoric acid or dithiocarbamate, which are also mainly used in PVC and styrene resin; their application effect in polyolefin resin is similar to that of cationic antistatic agent. Among anionic antistatic agents, sodium alkylsulfonate has been widely used in styrene resin, PVC, polyethylene terephthalate and polycarbonate |
