Surface treatment of zinc oxide

Last week, there was a customer from Japan sent us an inquiry about zinc oxide, the email content is showed as following. I would like to ask another questions below. ・Grain size of the zinc oxide.(μm) ・The purchase price in Japan.(estimations) ・With or without of treating the surface of grains. In last article, i explained the first question about the Grain size of zinc oxide. Today i will introduce the third question, the surface treatment of zinc oxide.

About the surface treatment of zinc oxide information.





Last week, there was a customer from Japan sent us an inquiry about zinc oxide, the email content is showed as following.

I would like to ask another questions below.

Grain size of the zinc oxide.(μm

The purchase price in Japan.(estimations)

With or without of treating the surface of grains.

In last article,  i explained the first question about the Grain size of zinc oxide. Today i will introduce the third question, the surface treatment of zinc oxide.

In our lab,  i asked our engineer, Zinc oxide is white powder, why this customer asked us that “ with or without of treating the surface of grain.”

Mr. Chang, our engineer told me, some factory buy zinc oxide,  in order to protect the enviroment, they would ask us to add a process, make the powder to grain, then in the process of use the zinc oxide, it would to avoid the dust pollution.

I asked our engineer, could we do the surface treatment of zinc oxide ? Mr. Chang said, of course, we could do it. Surface treatment of zinc oxide is easy in our factory. If our customer needed, we did it well.

But Mr.Chang remind me another question, during the transportation, the grain would become smaller than loading, that will be attented.

Following is the specification of the zinc oxide in our factory. It’s the normal

The following is the specification of zinc oxide produced by our factory, which is only the specification of the most common products. If customers have special requirements for the products, such as particle size, lead content, etc., we can customize them.
