硬脂酸钙的生产方式有哪几种?
来源:http://www.jnjrh.com 日期:2019-03-29 发布人:admin
硬脂酸钙可分为固性硬脂酸钙和水性硬脂酸钙,用途广泛,硬脂酸钙的生产方法有三种:水法和熔融法、直接法,通常来说,水法生产地硬脂酸钙显酸性,熔融法显碱性,具体如下:
  Calcium stearate can be divided into solid calcium stearate and water calcium stearate, which are widely used. There are three production methods of calcium stearate: water method and melting method, direct method. Generally speaking, the production of calcium stearate by water method is acidic and the melting method is alkaline, as follows:
  1、水法又称湿法 是指当水为介质时,加入一定量的催化剂,控制好合适的温度、压力,然后加入一定量的金属氢氧化物,金属离子会通过催化剂被置换到催化剂上,然后通过催化剂再置换到硬脂酸上,会生成金属盐,
  1. Water method is also called wet method. When water is used as medium, a certain amount of catalyst is added to control the appropriate temperature and pressure, and then a certain amount of metal hydroxide is added. Metal ions will be replaced on the catalyst through the catalyst, and then on stearic acid through the catalyst, metal salts will be formed.

  What are the three main production methods of calcium stearate?
  催化剂经过后序处理,循环利用,硬脂酸盐经过离心、烘干、研磨得到目数在200-600目的符合行业标准的产品,水法生产通常硬脂酸会稍过量,因此反应后成品显酸性。
  Catalyst is recycled after sequencing treatment. Stearate is centrifuged, dried and grinded to produce products with a mesh of 200-600 in line with industry standards. Water method usually produces a little excessive stearic acid, so the product is acidic after reaction.
  2、熔融法又称干法,是指在熔融的硬脂酸中,直接加入金属氧化物(间接法氧化锌),(当然在催化剂存在的条件下,不然反应的转化率会很漫长很漫长的)控制一定的温度压力及搅拌速度,通过反应得到硬脂酸盐,干法生产的产品由于催化剂的存在一般的反应结果都可以得到完全反应,金属氧化物稍过量,因此检测上的时候产品显碱性。

  2. Melting process, also known as dry process, refers to the direct addition of metal oxides (indirect method of zinc oxide) into molten stearic acid. (Of course, in the presence of catalysts, otherwise the conversion of the reaction will be very long and long.) Controlling a certain temperature, pressure and stirring speed, stearate can be obtained through reaction. The products produced by dry process have general reaction knots due to the presence of catalysts. All the fruits can be completely reacted, and the metal oxides are slightly excessive, so the product is alkaline when tested.
  3、直接法(硬脂酸和氢氧化钙在水环境下直接反应生成硬脂酸钙)。
  3. Direct method (direct reaction of stearic acid and calcium hydroxide to produce calcium stearate under water environment).
  生产工艺的好坏直接影响着产品的质量,看了上述对硬脂酸钙生产方法的介绍是不是对硬脂酸钙有了更进一步地了解了呢,希望对你有帮助哦!
  The quality of the product is directly affected by the quality of the production process. See the above introduction of the production method of calcium stearate, do you have a better understanding of calcium stearate, I hope it will help you!
