Zinc stearate superfine grinding solution


Zinc stearate is a "zinc soap" that is widely used industrially. In this context, soap is used in its formal sense, a metal "salt" of a fatty acid. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the most powerful mold release agent among all metal soaps. It contains no electrolyte and has a hydrophobic effect. Its main application areas are the plastics and rubber industry, where it is used as a releasing agent and lubricant which can be easily incorporated.

Zinc carboxylates, e.g. basic zinc acetate, adopt complex formulas, and are not simply dicarboxylates of zinc. Instead the formula for most zinc carboxylates is Zn4O(O2CR)6, consisting of a Zn4O6+ core with carboxylate ligands spanning the edges.

It is widely used as a release agent for the production of many kinds of objects rubber, polyurethane, polyester processing system, powder metallurgy. These applications exploit its "non-stick" properties. In cosmetics, zinc stearate is a lubricant and thickening agent used to improve texture.

It is an "activator" for rubber vulcanization by sulfur and accelerators. As discovered in the early days of vulcanization, zinc has a beneficial effect on the reaction of the sulfur with the polyolefin. The stearate is a form of zinc that is highly soluble in the nonpolar medium of the polyolefins.

Being lipophilic, it functions as a phase transfer catalyst for the saponification of fats.

The ACM/A series are highly efficient super-fine punch-action mechanical micro grinding machines of performing the complete process of material grinding, separation and making of the finished product within the same tightly integrated system.

1. Built-in separation mechanism-preventing over-grinding.

2. Able to produce uniform granules of required sizes by adjusting the speed of the stage-separation wheel(s) or by adjusting the strength of the blower(s).

3. Powerful blowing and strong self-cooling capability, suitable for grinding heat-sensitive materials.

4. Different grinding accessories/devices are used according to the hardness of the material being ground; different types of materials (alloyed carbon steel, stainless steel, ceramics etc) are available for the Machine's inner linings and product extracting system, meeting the needs of different industries.

5. Both manual and programmable auto-controlled machines available.

The machine is suitable for super-fine grinding of various types of brittle materials. Material hardness (Mohs scale)<4, moisture contents<10%, input size 5-200mm (as decided by the model of the machine and material hardness). The machine is widely used coating materials and other industries.
