其他信息

  • 方法一:采用复分解法。先将硬脂酸以20倍重量的热水溶解，在90℃左右加入浓度10波美的烧碱，生成稀皂液。然后，在同一温度下加入硝酸铅溶液进行复分解。产生的硬脂酸沉淀用水洗涤，离心脱水，再于100℃左右进行干燥，即得成品。原料消耗定额：硬脂酸（酸值198-205，碘值<4）740kg/t、烧碱（30%）370kg/t、乙酸铅（98%）540kg/t。
  • 用途三:用作聚氯乙烯塑料的稳定剂
  • 下游产品:乳液防水剂
  • 用途四:用作聚氯乙烯的热稳定剂和润滑剂和润滑剂，热稳定产能比硬脂酸钙大，并兼有较好的光稳定作用。主要用于各种不透明的硬质的软持聚氯乙烯制品，制别适用于电线电缆料，可赋予制品优良的电性能。一般用量为0.5-2份。
