    硬脂酸钙

    关于此产品

    硬脂酸钙由硬脂酸与钙源反应制得,是一种不溶于水的白色固体。供货指标为钙含量 6.5-7.1%、游离脂肪酸≤0.5%、熔点 149-155C、加热减量≤3.0%;形态为 125 目、200 目或 325 目粉末以及珠粒和颗粒,后者熔点 140-160C,适合低粉尘作业环境。植物基产品,脂肪酸来自棕榈。

    金属皂是至今仍在大规模工业使用的最早一批油脂化工衍生物,而硬脂酸钙依放置位置不同承担三种性质迥异的工作。作为润滑剂,它迁移到熔体与约束熔体的金属之间的界面上,极性羧酸根端锚定在金属表面,C18 链则形成一层低摩擦层;作为脱模剂,同一层疏水膜阻止制品润湿模具。作为酸吸收剂,它所做的事在化学上完全不同:硬脂酸根捕获酸性物质,钙与酸结合并释放出硬脂酸,因此在残留催化剂或反应析出的酸会侵蚀聚合物的场合往往选用它。对沿棕榈产业链向下游延伸的买方而言,它比水解和分提又进了一步:脂肪酸已被转化为具有明确金属含量的功能性衍生物,而不再是按碳链长度分割出售的大宗馏分。

    应用于金属皂生产、用作润滑剂与脱模剂、脂肪酸衍生物以及工业配混。

    Bio Green Oleo 按钙含量、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钙。
