What is the difference between Ordinary Zinc Oxide and Active Zinc Oxide ?
Active zinc oxide is a kind of versatility of new inorganic materials , the particle size is about 1 ~ 100 nm .
The particularity of Active cannot compare with ordinary zinc oxide . The active one is better .
Wet Method Process Active Zinc Oxide Description :
Generated by the reaction of zinc ash and sulfuric acid , sodium carbonate and ammonia respectively and then reacted with to produce zinc carbonate and zinc hydroxide as raw material of producing zinc oxide . The reaction equation is as follows:
Zn + H2SO4 → ZnSO4 + H2 ↑
ZnSO4 + Na2CO3 → ZnCO3 ↓ + Na2SO4
ZnSO4 + 2NH3 · H2O → Zn (OH) 2 ↓ + (NH4) 2SO4
Zinc carbonate as raw material , washing , drying , calcination , crushing obtained zinc oxide product .
ZnCO3 → ZnO + CO2 ↑
Zinc hydroxide as a raw material , the precipitate was washed with water, dried and calcined , cooled and pulverized to obtain a zinc oxide product .
Zn (OH) 2 → ZnO + H2O
Wet Method Process Active Zinc Oxide Advantages :
(1) By adjusting the process parameters , Using Wet Method can produce various purity , size and color active zinc oxide types . ( we supply a variety of zinc oxide products )
(2) The process can use a variety of materials as the zinc raw material , which is converted into high value-added zinc oxide products . ( our quality is guaranteed )
(3) Typical green chemical process , are environmentally friendly process .
Nano zinc oxide key features :
(1) strong activity ; making the vulcanization reaction strong , therefore , it can reduce the dosage or shorten curing time . ( 70%-80% active zinc oxide is okay )
(2) the proportion is small , less harmful substance content ( such as Pb, Hg, Ge, Mn, etc. ) .
(3) nano zinc oxide blended with rubber , dispersed evenly , can improve the viscosity of the rubbe r, so less dosage of nanometer zinc oxide is better than ordinary zinc oxide .
(4) can improve the stability and thermal conductivity of the shape of the products .
Active Zinc Oxide Used for Catalyst Application :
Nanometer zinc oxide is better than Ordinary zinc oxide ?
Nanometer zinc oxide as the gas through the diffusion speed is faster , therefore it is an excellent catalyst . Nano zinc oxide because of its small size , large specific surface area , surface key and particles from inside , it increases the interface reaction, catalytic activity and selectivity of nanometer zinc oxide is far greater than its traditional catalysts .
Why Nanometer zinc oxide is of super quality ?
Nanometer zinc oxide is a kind of very good light catalyst . Harmful organic substances such as chlorine , pesticides , surface active agents , pigment , etc. , with the current water treatment technology is difficult , nano zinc oxide as catalyst of light can make the decomposition of organic matter .
ZnO used as photocatalyst :
Surface of study , zno nanoparticles reaction rate is 10-1000 times than that of ordinary zinc oxide particles , and compared with the ordinary particles , it almost does not cause the scattering of light , and there are large specific surface area and wide band , therefore it is considered to be highly applied prospect of one of the photocatalyst .
