The active aluminum content of aluminum silver paste has been tested, the higher the better, the explosive power of fireworks and firecrackers, and the gloss of paint Sieving of degree, brightness, number of phases.
Because aluminum silver paste is widely used, the demand is relatively large, and there are many varieties. Therefore, it is a large category of metal pigments. The aluminum powder particles used in the pigment are scaly. It is precisely because of the scaly particle state that aluminum powder is used. It has metal color and shielding function. The industrial production of metal aluminum powder has existed a long time ago. The early production method was the back-punching method. The rate of debris was placed in the groove of the ramming machine, and the ramming was continuously impacted by the machine. The aluminum scraps in the punching grooves have ductility and gradually become flakes and shattered under impact. After the aluminum becomes very thin and small, they are screened, and the aluminum powder that meets the requirements is taken out as the product. The production efficiency of ramming is low. I don’t agree with the quality of the product, and there is too much dust in the production process, which is very easy to catch fire or explode.
