Ultra ince toz, yaln\u0131zca yap\u0131sal malzemelerin haz\u0131rlanmas\u0131 i\u00e7in bir temel de\u011fil, ayn\u0131 zamanda \u00f6zel i\u015flevlere sahip bir malzemedir. alan gereklidir. Ultra ince tozun modern end\u00fcstride giderek daha yayg\u0131n bir \u015fekilde uygulanmas\u0131yla, toz i\u015flemede toz s\u0131n\u0131fland\u0131rma teknolojisinin konumu giderek daha \u00f6nemli hale geliyor.<\/p>\n
1. S\u0131n\u0131fland\u0131rman\u0131n anlam\u0131<\/p>\n
Toz haline getirme i\u015fleminde, tozun yaln\u0131zca bir k\u0131sm\u0131 genellikle par\u00e7ac\u0131k boyutu gereksinimlerini kar\u015f\u0131lar. \u0130htiyaca ula\u015fan \u00fcr\u00fcnler zaman\u0131nda ayr\u0131\u015ft\u0131r\u0131lmaz ve par\u00e7ac\u0131k boyutu gereksinimlerini kar\u015f\u0131lamayan \u00fcr\u00fcnlerle birlikte toz haline getirilirse enerji israf\u0131na ve baz\u0131 \u00fcr\u00fcnlerin a\u015f\u0131r\u0131 k\u0131r\u0131lmas\u0131na neden olur.
\nEk olarak, partik\u00fcller belirli bir dereceye kadar rafine edildikten sonra, ezilme ve topaklanma olgusu ortaya \u00e7\u0131kacak ve hatta daha b\u00fcy\u00fck partik\u00fcl topakla\u015fmas\u0131 nedeniyle k\u0131rma i\u015flemi bozulacakt\u0131r. Bu nedenle ultra ince toz haz\u0131rlama s\u00fcrecinde \u00fcr\u00fcn\u00fcn s\u0131n\u0131fland\u0131r\u0131lmas\u0131 gerekmektedir. Bir yandan, \u00fcr\u00fcn\u00fcn partik\u00fcl boyutunun gerekli da\u011f\u0131l\u0131m aral\u0131\u011f\u0131nda olmas\u0131 kontrol edilir; Daha sonra k\u0131rma verimlili\u011fini art\u0131rmak ve enerji t\u00fcketimini azaltmak i\u00e7in ezin.<\/p>\n
Gerekli toz inceli\u011finin iyile\u015ftirilmesi ve \u00e7\u0131kt\u0131n\u0131n artmas\u0131yla, s\u0131n\u0131fland\u0131rma teknolojisinin zorlu\u011fu gittik\u00e7e artmaktad\u0131r. Toz s\u0131n\u0131fland\u0131rma sorunu, toz teknolojisinin geli\u015fimini k\u0131s\u0131tlaman\u0131n anahtar\u0131 haline gelmi\u015ftir ve toz teknolojisindeki en \u00f6nemli temel teknolojilerden biridir. bir. Bu nedenle, ultra ince toz s\u0131n\u0131fland\u0131rma teknolojisi ve ekipman\u0131 \u00fczerine ara\u015ft\u0131rma yapmak \u00e7ok gereklidir.<\/p>\n
