CAS 557-05-1 Zinc Stearate Powder

Description of Zinc Stearate Powder:

Chemical property

Zinc stearate powder is an organic salt produced by the reaction of stearic acid and zinc salt. It has stable chemical properties, is insoluble in water, and is easily soluble in organic solvents. At room temperature, zinc stearate powder does not react with common acids, bases, salts, and other substances and has good chemical stability.

Physical property

Zinc stearate powder is white or light yellow solid, tasteless, non-toxic, and the specific gravity is about 1.9. Its particles are delicate, easy to disperse, and have good lubricity and fluidity. In addition, zinc stearate powder also has good electrical insulation properties and moisture resistance.

Thermal stability

Zinc stearate powder has good thermal stability and is not easy to decompose or oxidize at room temperature. However, under high-temperature conditions, zinc stearate powder will gradually lose water and oxidize and change color. Therefore, in preparation and use, it is necessary to control the temperature and humidity.

Hygroscopicity

Zinc stearate powder has strong water absorption, which will affect its lubricity and fluidity after absorbing water. Therefore, during storage and use, it is necessary to avoid contact with moisture.

Lubricity

Zinc stearate powder has excellent lubricity, which can reduce friction coefficient, reduce wear and friction, and improve mechanical efficiency. Therefore, zinc stearate powder is widely used in lubricants, release agents, anti-wear agents, and other fields.

Wear resistance

Zinc stearate powder has good wear resistance, can reduce mechanical wear and friction, and prolong the service life of equipment. Therefore, zinc stearate powder is widely used in anti-wear agents, lubricants, and other fields.

Weather fastness

Zinc stearate powder has good weather resistance and can resist the influence of environmental factors such as light, oxidation, and high temperature. Therefore, zinc stearate powder is widely used in outdoor supplies, auto parts, coatings, and other fields.

Toxicity safety

Zinc stearate powder is a low-toxic substance that has no apparent harm to the human body and environment. However, prolonged exposure to zinc stearate powder may cause skin and respiratory irritation. Therefore, during production, use, and storage, measures need to be taken to prevent inhalation and contact with the skin.

Production Method of Zinc Stearate Powder: 

Raw material preparation

The raw materials for producing zinc stearate powder include stearic acid and zinc salt. Among them, stearic acid can be selected as industrial grade or food grade stearic acid, and zinc salts usually choose zinc nitrate or zinc chloride.

Mixed

Stearic acid and zinc salt are mixed proportionally, usually by ball milling or stirring. It is necessary to control the temperature and mixing speed during the mixing process to ensure the raw materials are thoroughly mixed.

Heating reaction

The mixed raw material is put into the reactor and heated to a specific temperature for reaction. The reaction temperature and time must be controlled during the reaction process, generally heated by oil or water baths.

Cooling and grinding

After the reaction, the product is removed and cooled to room temperature. Then, it is ground into a powder by grinding equipment.

Drying and packing

The ground powder is dried to remove moisture and volatile components. Attention should be paid to controlling temperature and humidity during the drying process to prevent deterioration or caking of the product. Finally, the dried powder is packed for use.

It should be noted that the specific production methods and process parameters may vary according to different manufacturers and product requirements. In the production process, it is necessary to adjust and optimize according to the specific situation and pay attention to the control of raw material quality, reaction conditions, product quality, etc., to ensure that the production of zinc stearate powder meets the requirements.
