crude zinc oxide Zinc oxide as white pigment. Due to the activity of good performance of zinc in rubber, activate are getting more and more widely, such as V belt can not only releases instead of ordinary zinc oxide, and can reduce 1/2-1/3, the dosage of rubber vulcanization performance, stable performance, reduce the production cost. Zinc can make the fine grained pharmaceuticals. Because ultraviolet absorption ability of zinc oxide, people pay more and more attention on zno on cosmetics, such as development of 0.01-0.04 um particle of zinc oxide particles, the ultraviolet absorption, transparency are always with tio2 than particles.
