Product Introduction
A copper powder manufacturing process
Copper powder is a kind of copper-zinc-based raw materials, through melting, dusting, milling, polishing and other processes processed very fine scaly metal powder, also known as copper-zinc powder, commonly known as powder.
Second, copper powder characteristics
1 bronze powder composition and hue
Copper alloy composition is different because of the surface may be in crimson, gold, white and even purple color with different content of zinc, copper powder presents a variety of different hues, less than 10% zinc to produce pale gold effect, known as the red gold; 10% --25% developed rich pale gold effect, known as green and red gold; 25% --30% developed rich pale gold effect, known as green gold.

2 bronze powder morphology and particle release
Copper powder particles are scaly structure, observed in a scanning electron microscope, copper powder scales majority is irregular, jagged edge shape, a small amount is rounded more rules. This particle structure determines it has characteristics to be coated are arranged in parallel.

Features 3 floating bronze powder
Bronze powder after floating refers flake copper powder pigment with a suitable binder mixture, it can float on the surface of the bonding material to form a parallel to the substrate, overlapping metal after printing.

4 bronze powder surface covering rate
The size of the surface cover ratio is an important indicator of the quality of the surface of the copper powder, it refers to a monolithic unit mass of copper in the form of powder floating on the water can cover the area, the unit to c㎡ / gb representation.

Copper powder is a flake pigment floating by a certain percentage of copper, zinc, and aluminum melting milling, grading to the required specifications. Southern European copper powder production powder hues: red gold, green gold, green and red gold, bronze gold and other colors.

5 of the optical properties of copper powder

As one of the copper-zinc alloy metal powder pigment main characteristic is the "flop" phenomenon refers to vary the viewing angle can be flashed different brightness, saturation, hue have optical phenomena, is a pigment incident light scattered and reflected different way caused this phenomenon and the flatness of the metal surface is related to the smooth surface of the material, the higher the brightness. Factors affecting the copper powder India Jin Guangze degree by many, including morphology bronze powder, sheet thickness and the arrangement plays a vital role in the orientation of the bonding compound.

6 The use of copper powder

400 mesh copper powder: Flying gold, gilded, gold printed fabric, also suitable for screen printing, wallpaper, paint and incorporated into plastics. Features: high light, strong metal.
600 mesh copper powder: Flying gold, gilded, gold fabric printing, screen printing, coating and other crafts. Features: high light, strong metal.
800 mesh copper powder: for textile printing, plastic spray paint, plastic, wallpaper "tipping" Paint aqueous and non-aqueous applications. 1000 mesh copper powder: used in the manufacture of high brightness paint spray glue, wooden materials, printing inks and rubber convex plate ink. Features: Fine, high brightness.
1200 mesh copper powder: suitable for printing ink, paint, plastic, silk screen inks. Features: high brightness.
1500 mesh copper powder: excellent performance, high gloss, good stability, it can be used in the manufacture of canned offset printing inks.


7. The production process (powder production process)

Copper Electrolysis → milling → grading → Test → polishing → stirring → Packaging → storage
Detection: Qualified on polishing
Failure to identify, isolate, and promptly failed rework
