Practical techniques of metal powder coatings Notes

Posted by tracy ma on Friday, November 4, 2011, In : metal powder 

Metal powder coating is a metal-containing pigments (such as: copper powder(FCu), silver, aluminum, etc.) of powder coatings. As the metal powder coating to show a bright, luxurious decorative effect, very suitable for furniture, jewelry and cars indoors, spray the object outside. In the manufacturing process on the domestic market mainly by dry mixing method (Dry-Blending), also used the international bond fixation (Bonding).

What is iron powder?

Posted by tracy ma on Tuesday, November 1, 2011, In : metal powder 
Iron powder is an important raw material metal powder. Iron extraction and industrial applications began in the 1920s. At that time the German production of electrolytic iron and carbonyl iron powder, mainly used as a catalyst for the chemical industry. 30 years to begin production of iron-based powder metallurgy parts. Vortex developed in Germany in 1933, the production of iron grinding. Swedish sponge iron production in 1936 based on the use of magnetite produced by the reduction of low-cos...
