Bronze Powder Picture
DESCRIPTION
Bronze powder, also known as copper-zinc-gold powder, gold powder. It is a kind of floating flake pigment, which is made of a certain proportion of copper, zinc and aluminum alloy, dissolved into copper water, atomized into copper sand, then washed, de-dried, dried and then entered into dry grinding, adding grinding aids and brighteners, Antioxidant, and then cut the material at different discharge ports through sorting, and then enter polishing, sorting and screening.
COMPOSITION AND HUE
The surface of copper powder can be red, golden, white or even purple due to its different composition. The color of copper and gold powder varies with the content of zinc.
Containing Zinc below 10% produce pale gold effect.
10%-25% produces rich light golden effect, called rich pale gold.
25%-30% produces rich light golden effect, called rich gold.
MICROSTRUCTURE AND PARTICLE SIZE DISTRIBUTION OF BRONZE POWDER
The bronze powder particles are flaky texture. Observed under a scanning electron microscope, the flakes are mostly irregular, with a sawtooth shape on the edge, and a small amount of it is a relatively regular circle. The structure of this particle determines that it has the characteristic of being arranged parallel to the coated object.
BRONZE POWDER OPTICAL PROPERTIES
The bronze powder has the angle-following color dissimilation effect, it is related to the smoothness of the metal surface. The Microstructure, coating thickness and particle size distribution all plays a vital role to influence the glossiness of printing gold.
SIZES
300 mesh, 400 mesh, 600 mesh, 800 mesh, 1000 mesh, 1200 mesh, 1500 mesh, gravure printing powder, offset printing powder
SERIES
Universal copper and gold powder, Water-based environmental protection copper and gold powder
Remark:
W
ater-based environmental protection copper and gold powder
The surface of this series of copper-gold powder is double-coated with silica and organic surface treatment agent. The coating thickness is uniform and dense, and does not affect the metallic luster of metal particles. During long-term storage, water or alkaline substances are not easily penetrated. The coating layer does not produce corrosion and hue changes. The product can be widely used in water-based coating systems.
Main use
Widely used in plastics, silicone, printing, printing, leather, toys, home decoration, cosmetics, handicrafts, Christmas gifts and other industries.
Packing
25kg/drum, then packed with pallet
