Indirectness Zinc oxide
Product Property:
1. Molecular Formula: ZnO Molecular Weight: 81.38
2. Appearance Character: white six-angled crystallization or powder, tastelessness, nontoxic and delicacy.
3. It is dissoluble in acid, NaOH, NH
4C1 while indissoluble in water ethanol, and ammonia water. It is belongs to ambisexual oxide and has the function of absorbing ultraviolet rays.
Produce Usage:
It is abundantly applied in rubber industry, as it can enhance rubber product in elasticity and rub resistance. It is indispensable white paint in painting industry. Besides it's physical features, it also has the function of antisepsis, antifungi, anti-powdered, enhancing durability. Zinc oxide can also applied as intermedium in producing many chemical engineering materials and in pottery and porcelain, glass and textile industries. For example, it can be produced to rubber softener by react with organic acid which is intermedium in synthesizing zinc sulphide material.
