Flake zinc powder
Product properties:
Formula: recent molecular weight: 65.38
Physical properties: appearance for aluminium flake powder.
Production methods: the product adopts the domestic leading wet physical methods of production.
Product use:
Is mainly used in diao meetall, dacromet coating technology and flipping yellow zinc coating liquid and is widely applied in the development and production of organic and aqueous coating, cars, radar, ships, tanks, car accessories, tower scaly surface treatment such as powder coating are used zinc powder.
Mechanism and characteristic is outlined
Applications in coatings, electrochemical, zinc and iron basic compared to more negative potential, in the dielectric converted into solution, thus protecting the basic iron.If the coating is broken, basic metal exposed, it is more so;Sealing and sealing, due to the corrosion of zinc powder reactant znco3 (mainly alkaline zinc carbonate, 2, 3 zinc (OH) 2) deposit between zinc powder particles, the space between the fill paint, again not conductive, and coating have played an important role in closed;Shielding effect, as a result of flake zinc powder in the coating surface parallel to the film, and the overlap and crisscross, greatly increased the water and corrosive medium penetration distances coating, to improve the coating corrosion resistance ability.
Liquid containing zinc coating formulation and performance
Flake zinc powder with a variety of resin made from zinc rich primer, such as ethyl silicate, epoxy ester, epoxy and polyurethane etc.From the structure into consideration, even if this formula in zinc dosage less than ordinary zinc powder paint, also won't reduce the anticorrosion properties of the coating.In waterborne zinc rich primer formula to add other anticorrosive pigments and flake pigments, such as micaceous iron oxide, mica powder, etc.Can reduce the dosage of flake zinc powder accordingly, also make have the effect of compound corrosion resistance;Containing zinc waterborne anti-corrosion coating liquid can be as paint can also be used as primer, greatly enhance the anticorrosion performance.
