What are the uses of talc powder
1. Production of cosmetics
Talcum powder is an important raw material for the production of cosmetics, as it contains a large amount of silicon, which can prevent infrared radiation. Therefore, when processing some sun protection cosmetics, an appropriate amount of talcum powder is added, which can significantly improve the sun protection and infrared resistance of cosmetics.
2. Making fillers
Talcum powder has good suspension and dispersibility, as well as low corrosiveness. In coatings, talcum powder as a filler can serve as a skeleton, reducing manufacturing costs and improving the hardness of the coating film. Especially when producing PP based materials, an appropriate amount of talc powder can be added, which can significantly enhance the elasticity and stretchability of PP materials, and make the produced materials have higher utilization value.
3. As a protective agent for agricultural film
Talcum powder has a strong shielding effect on infrared radiation. When producing agricultural films, an appropriate amount of talcum powder can be added to improve the infrared barrier of these films. After use, this type of agricultural film can prevent the evaporation of heat inside the greenhouse, increase the temperature inside the greenhouse, and keep the temperature inside the greenhouse stable.
4. Food additives
Edible talc powder is used as an additive in the pharmaceutical and food industries. It is non-toxic, odorless, has a soft taste, and strong smoothness, so it can be consumed, but excessive or long-term consumption can cause cancer.
2、 What are the benefits and effects of talc powder
1. Protecting the skin and mucous membranes. Talcum powder, due to its small particle size and large total area, can absorb a large amount of chemical irritants or toxins. Therefore, when spread on the surface of inflamed or damaged tissues, it can have a protective effect; When taken orally, in addition to protecting the inflamed gastrointestinal mucosa and exerting antiemetic and antidiarrheal effects, it can also prevent the absorption of toxins in the gastrointestinal tract. Talcum is not entirely harmless and can cause granulomas in the abdomen, retum, vagina, and other areas.
Function: Cosmetic additive.
Effect: Contains a large amount of silicon element, which can block infrared radiation, thereby enhancing the sun protection and anti infrared performance of cosmetics.
Function: Used as an enhanced filler.
Effect: Talc powder filled modified PP has higher tensile modulus and bending modulus. It can increase the tensile and bending stress of the material.
Function: Used as an agricultural film insulation agent.
Effect: Silicon containing minerals have a blocking and shielding effect on infrared radiation. Adding an appropriate amount of this mineral powder to agricultural greenhouse film can improve the infrared barrier of plastic film, thereby reducing the heat inside the greenhouse to dissipate outside in the form of infrared radiation at night, and improving the insulation of the greenhouse.
