The influence of the basic indexes of MST® French Process Zinc Oxide Powder Factory on the production of zinc stearate:
1) Whiteness: There are many factors influencing the color of zinc stearate. Among them, the whiteness of French Process Zinc Oxide Powder Factory is very important. The higher the whiteness of zinc oxide, the color of zinc stearate produced the more white.
2) Other metal content: The content of other metals contained in French Process Zinc Oxide Powder Factory will directly affect the free acid index, transparency, and insoluble matter of zinc stearate. Therefore, the content of other metals in French Process Zinc Oxide Powder Factory used in the production of zinc stearate is required to be less than 20PPM.
3) Zinc content: Zinc content will affect the free acid index of zinc stearate, and MST® French Process Zinc Oxide Powder Factory with too low zinc content will increase the cost of producing zinc stearate.
4) Activity: The activity of MST® French Process Zinc Oxide Powder Factory will affect the production rate of zinc stearate. Too low activity will lead to slow reaction, long heating time, poor efficiency and yellowish color. Excessive activity will cause a violent reaction, which is difficult to control.
5) Fineness: The fineness of MST® French Process Zinc Oxide Powder Factory has an effect on the reaction of zinc stearate. The finer the fineness, the faster the reaction speed, and vice versa. The fineness should be in an appropriate range, too fast to react. Control, too slow cost increase.
