    关于此产品

    硬脂酸锌由硬脂酸与锌源反应制得,所得金属皂不溶于水、疏水,常温下为固体。供货指标为锌含量 10.5-11.1%、游离脂肪酸≤0.5%、熔点 119-125C、加热减量≤1.0%;形态为 125 目、200 目或 325 目粉末,以及适合低粉尘作业的珠粒、片状和颗粒。植物基产品,脂肪酸来自棕榈。

    除脂肪酸本身之外,它是用量最大的脂肪酸衍生物之一,原因在于疏水表面与较低熔点的组合。与对应的钙皂相比,它的熔点低约三十度,为 119-125C,金属含量则高出约一半;这两点差别决定了配混人员在什么场合选用哪一种,而许多配方会把两者搭配使用。熔点较低意味着这种皂在常规加工温度下即可软化铺展,在模具表面形成一层连续膜,而不是以离散颗粒的形式停留在那里,这正是脱模和防粘连场合通常选用它的原因。金属含量较高则意味着每加入一公斤可提供更多的锌。同样的疏水性使粉料在仓储中不易吸潮,但也让在极性体系中的润湿与分散成为这项工作中较难的部分。

    应用于金属皂生产、用作脱模剂与防粘连剂、脂肪酸衍生物以及工业配混。

    Bio Green Oleo 按锌含量、游离脂肪酸、熔点、加热减量、目数或颗粒形态及包装的规格要求供应硬脂酸锌。
