Product classification of zinc stearate

It can be divided into solid zinc stearate and aqueous zinc stearate

Production method

There are two methods for the production of zinc stearate: water method and melting method. Generally speaking, zinc stearate produced by water is acidic, while the melting process is alkaline.

The water method is also called the wet method. Under the condition of water as the medium, the catalyst is added, a certain temperature and pressure are controlled, and then the metal hydroxide is added, and the metal ions are replaced on the catalyst through the catalyst, and then replaced on the stearic acid through the catalyst itself, so as to achieve the purpose of generating metal salts. The catalyst is processed and recycled. Stearate is centrifuged, dried and ground to obtain 200-600 mesh in line with industry standards. Water production usually has a slight excess of stearic acid, so the finished product is acidic after the reaction.

The melting method, also known as the dry method, refers to the molten stearic acid, directly add metal oxide (zinc oxide), (of course, under the condition of the presence of the catalyst, otherwise the conversion rate of the reaction will be very long) control a certain temperature pressure and stirring speed, through the reaction to get stearate. Due to the presence of the catalyst, the general reaction results of the products produced by the dry process can be completely reacted, and the metal oxide is slightly excessive, so the products are alkaline when tested.
