[Uses] : 1, Chemical industry: , Average Size is 10-12μm .
2, zinc anticorrosive coating : for the anticorrosion of steel parts , coating methods
include dip coating , plating , hot spraying , high zinc coating, powder coating , and so
on. Dip coating is the main method. High zinc coating is suitable for large part , which is
unsuitable for dip coating & plating . High zinc coating includes organic high zinc
coating & inorganic high zinc coating . Organic high zinc coating 's base materials are
epoxy-ester ,
epoxy resin, chlorinated rubber, vinylite & PU resin , Zinc powder in dry
film is about 85%-92%.Inorganic high zinc's base materials are water-based lithium
metasilicate , water-based potassium silicate , TEOS or cement slurry , Zinc powder in
dry film is about
92%. Average Size of Zinc powder is 2-3μm & 5-7μm.
3, machine cementation & galvanized production: the galvanized process of machinery.
Our refined Zinc powder has several kinds of air speeds, Grade Grain size is from
300mesh to 1,500目mesh. Its Specifications include
5#, 6#, 8#, 10#, Our Zinc powder
for cementation has even Grain size and is hard to oxidized during the operation.
4, Hydrometallurgical concentration : the purification of solution and recovery of metal.
5, Pharmaceutical & pesticide :Zinc powder can be used as reductant and material of
drugs & pesticide .
[Packing] : steel pail & woven bag packing, lined with plastic bag, Net wt 50KG, or following your
demand.
[Transportation & storage] :
1, Zinc powder avoid moisture and fire, no knock and falling
2, Zinc powder should be kept in dry, fire-proofing and ventilating place. |
