摘要
电气石具有热释电效应、远红外辐射及释放大量负离子的特性,其超细粉体在纺织、涂料、水净化等领域有广泛应用。本文主要利用以气流磨和搅拌磨为主体的超细粉碎中试线,对电气石超细粉体的制备工艺进行了探讨。利用该工艺可以制备出亚微米和中位粒径小于100nm的电气石粉体,并且可实现工业化连续生产。
Tourmaline has the characteristics of releasing thermions, far-off infrared radiations and negative ions of oxygen. Ultra-fine powders of tourmaline have extensive applications in the fields of spin and weave, pigment and paint, as well as water purification. The preparation technology of ultra-fine tourmaline powder is discussed. The key equipment of a pilot plant to produce ultra-fine tourmaline powder with jet mill and stirred ball mill is described. Using this pilot plant facility we can produce tourmaline powder with particle size less than 100nm, and a continuous production process can be realized.
