What is the difference between aluminium powder and aluminium paste?
2018 / 06 / 04Aluminum powder is an important and widely used industrial raw material in modern industry. It is widely used in refractory materials, pigment coatings, ceramic alloys, chemical metallurgy, military industry and other industries.
According to different production technology, raw material aluminum powder under the electron microscope appearance mainly include water droplets shape and irregular shape, aluminum purity between 98-99.9% purity, activity aluminum purity between 96-99%. Aluminium purity and activity of the aluminum content are the two most important indicators of raw material quality of aluminum powder. In the application of aluminum powder of all raw materials, pigment aluminum powder and aluminum paste is the main applications.
The coating aluminum powder refers to the aluminum powder which is coated with aluminum powder . Coating aluminium flake shape has a good physical shielding characteristics, silver metallic luster, and with the Angle of different colored light effect, the senior fatty acid coated with aluminium powder pigment also has a floating performance in the film.
Aluminum paste is coating the mixture of aluminum powder and solvent, in paste form with the main components of aluminum flake, petroleum solvent and a little auxiliary. It can provide a silver metallic effect coatings and can mix together with other transparent color pigment.
The film present an evident flip-flop effect the decorating effect is beautiful and gorgeous.
Besides, it can be used in anti-corrosive paint for marine and container,cans. Moreover, it has some special effect, such as UV protection, high heat resistance etc.
Though the application about of aluminum paste and coating aluminum powder is roughly same, aluminum paste is easier to transport and is not dangerous, and aluminum powder is more likely to disperse ,but there are some risks in transportation and use.So the use of aluminum paste is more common, more volume.
