As the mainstream standard of indirect zinc oxide, the National Standard GB / T 3185-2016 is widely used in many fields, such as rubber tires, rubber products, phosphating solution, zinc stearate, paint pigments, petroleum additives, ceramics, glass and so on.

The National Standard No. GB /T 19589 - 2004 Analysis and Test Center of Tsinghua University analyzed the products through transmission electron microscope. The average particle size of nano zinc oxide is 20 ~ 30 nm, and the particle size of all particles is less than 50 nm. It has large specific surface area and strong activity and is widely used in various fields.

The National Standard No. HG / T 2572 - 2012 Activated zinc oxide is characterized by easy agglomeration and strong activity. At the same time, it has the dual characteristics of nano materials and traditional zinc oxide, and is widely used in various fields.
