Calcium stearate can be divided into solid calcium stearate and water-based calcium stearate, a wide range of USES, calcium stearate production methods have two kinds: water method and melting method, generally speaking, water production of calcium stearate acid, melting method alkaline. Below, with the nuojia plasticization to a detailed understanding.

1, the water is also called the wet method under the condition of water as medium, adding catalyst, control of temperature, pressure, and adding metal hydroxide, metal ion by catalyst on the catalyst, and then through the catalyst itself displacement to the stearic acid, so as to achieve the purpose of generating metal salts, catalyst through after the order processing, recycling, stearic acid salt after centrifugation, drying, grinding get mesh in 200-600 purpose products that meet the industry standards, production usually stearic acid will be slightly too much water, so the acid reaction after the finished product.

2, melting method, also known as dry process, it is to point to in the melting of stearic acid, directly add metal oxide (indirect method zinc oxide), (of course, in the presence of catalyst, or reaction conversion rate will be very long very long) control a certain temperature and pressure and stirring speed, is obtained by reaction stearic acid salt, dry products due to the presence of catalyst reaction results can be fully reflect, metal oxide is a bit too much, so when testing on alkaline products significantly.
