Scaly Zinc Powder
Product property:
Molecular Formula: Zn
Molecular Weight: 65.38
Physical Property: Silver grey scaly powder
Production Method: It uses the dry grinding physical method that advanced in China
Produce usage:
Medicine and farming chemical: Zinc powder, as a reducing agent, can be sued for producing salicylic acid. indometacin, amidopyrine, etc. As raw materials, it can be used for zineb, Zinc phosphoride, high-effective and low-poisonous kikumycin farming chemical, etc..
Brief description and characteristics of mechanism:
Application in coating: in electro-chemical, compared with basic iron, its electric position is more negative, and is easy to turn into solution to protect basic iron. If the costing layer is damaged, and the basic metal is exposed, then it has more function as above mentioned; seal and sealing performance: since the erosion reaction products of Zinc powder( mainly Alkali Zinc Carbonate 2ZnCO
3, 3Zn(OH)
2) deposit among Zinc powder particles to fill out the sew of dyestuff but not conduct, thus it play a role in sealing the coating layer; shielding effect: since scaly Zinc powder is ranged parallel to coating film surface and folds and crosses each other, thus it expands the distance of coating layer :penetrated by water and erosion media and enhances the anti-corrosive capability of coating layer.
Component and performances of coating with Zinc flake:
Mingled with various resins, scaly Zinc powder can be produced into Zinc-rich primer such as ethyl orthosilicate, epoxy ester, epoxy and polyurethane, etc. Considering construction, even Zinc flake contain in this formulation is less than common Zinc powder primer, it can not reduce its anti-corrosive capability, in formulation of water-borne Zinc-rich primer, adds other anti-corrosive dyestuff and flake dyestuff such as micaceous iron oxide, micaceous powder, etc, which can not only reduce the usage quantity of scaly Zinc powder but also has the compound anti-corrosive effect. water-borne coating containing Zinc flake can be used for coating or primer, which increases largely its anti-corrosive performance.
