Applications:
       1, rubber industry: rubber vulcanization active agents
       2, ceramic glass: lower coefficient of thermal expansion to prevent cracking, deformation, increase the brightness
       3, chemical treatment agent: response as zinc,dealt with before baking, with rust-proof, high adhesion, etc.
       4, the plastic industry: a variety of resins added to improve the quality of zinc oxide, zinc stearate made into a reaction stabilizer
       5, electronic components: soft magnetic
       6, coating paint: excellent resistance to ultraviolet, but also mold
       7, medicines and cosmetics: ointment or powder into the carrier
       8, animal feed: inorganic trace elements in minerals
