Zinc powder ball mill: zinc powder processing and milling equipment technology and use

Posted on

Zinc powder is dark gray powdery metal zinc, strong hiding power, has the effect of a good resistance to atmospheric corrosion and rust, commonly used to manufacture a strong reducing agent ﹑ rust, pigments and the like can be used. Zinc powder ball mill is the key equipment for zinc powder processing and milling. The anti-rust paints and pigments that have been made are used in the decoration of houses, and are more environmentally friendly.

1. Zinc powder processing and milling process

Zinc powder can be used to form a zinc slurry of scale structure by ball milling. The zinc powder and the ball milling medium are added into a closed roller ball mill, and a composite auxiliary agent is added to the roller ball mill, and a mixed gas of inert gas and air is introduced. The temperature inside the roller ball mill is maintained at 30-80 ° C, and then ball-milled for 5-20 h at a rotation speed of 30-100 r/min to obtain an average particle size of 5 to 25 μm, a bulk density of 0.7 to 1.2 g/L, and a pass of 45 μm. Ultrafine flake zinc powder with a sieving ratio of ≥98% by weight under the sieve. The zinc powder of the scale structure has a large hiding power, and the amount of zinc powder is less than that of the granular zinc powder when the coating is resistant.

Second, the powdered zinc powder helps green home construction

1. After the grinding, the zinc powder shields the interior decoration UV

In the coating industry, zinc powder has tinting strength and hiding power, and is a preservative and luminescent agent in coatings. In addition, the excellent ultraviolet shielding ability of nano zinc oxide makes it more prominent in the anti-aging of coatings. And has antibacterial, anti-enzyme, deodorant and other effects.

2, indoor humidity adjustment master

The high surface activity of the nano zinc oxide can improve the selectivity and catalytic efficiency of the catalyst, and can absorb moisture. When the humidity in the room rises, the ultrafine pores of the zinc powder can automatically absorb the moisture in the air and store it. If the moisture in the indoor air is reduced and the humidity is lowered, the zinc powder can release the moisture stored in the ultrafine pores. (
