Read： 1487 Time：17months ago Source：Transform the World with Simplicity

As an important inorganic compound, zinc sulfide is widely used in industry and daily life. Below we will understand the use of zinc sulfide from several aspects.

1. rubber production

zinc sulfide is an important rubber processing aid, can be used in the vulcanization reaction of rubber products, at the same time can improve the strength and hardness of rubber, and extend its service life. In addition, zinc sulfide can also improve the heat resistance and cold resistance of rubber products, improve its anti-aging and anti-ultraviolet ability, widely used in vehicle tires, sealing products, cable materials and other fields.

2. adhesive

zinc sulfide as an excellent curing agent, also has important applications in adhesives. Compared with organic peroxides, zinc sulfide does not release harmful substances and can provide better lateral linkage effect, so it is widely used in adhesives such as rubber, plastic, polyester resin, etc., especially in high temperature and high humidity environment.

3. coatings, zinc sulfide can be used as a filler and stabilizer to make the coating more stable and adhesive, while also improving its heat resistance and weather resistance. In addition, zinc sulfide also has the effect of absorbing ultraviolet rays and anti-corrosion, and has a wide range of applications in the fields of fire retardant coatings, water-based coatings, and architectural coatings.

4. sunscreen

zinc sulfide has excellent sunscreen function. Its particle size and composition structure can effectively absorb ultraviolet rays without leaving white marks on the skin. Therefore, zinc sulfide is widely used in cosmetics, daily necessities, sunscreen products and other fields.

5. photocatalyst

zinc sulfide can also be used in the field of photocatalyst, that is, through the artificial light source (such as ultraviolet lamp) irradiation of zinc sulfide, the surface of the formation of active intermediates, which can be pollutants and harmful gases in the air into harmless substances, has a wide application prospect.

Generally speaking, zinc sulfide is a very practical inorganic compound, which has a wide range of applications in many fields. I believe that with the continuous development of science and technology, its scope of application will continue to expand.
