Ultra ince tozlar\u0131 haz\u0131rlamak i\u00e7in bir\u00e7ok y\u00f6ntem vard\u0131r ve bunlar genellikle haz\u0131rlanma prensiplerine g\u00f6re kimyasal sentez ve fiziksel k\u0131rma y\u00f6ntemleri olarak ikiye ayr\u0131l\u0131r. Kimyasal sentez y\u00f6ntemi, iyonlardan, atomlardan vb. \u00e7ekirdek olu\u015fumu ve b\u00fcy\u00fcmesi yoluyla kimyasal reaksiyonlar yoluyla toz elde etmektir. Kimyasal y\u00f6ntemle haz\u0131rlanan ultra ince tozlar, k\u00fc\u00e7\u00fck par\u00e7ac\u0131k boyutu, dar par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131, iyi par\u00e7ac\u0131k \u015fekli ve y\u00fcksek safl\u0131k avantajlar\u0131na sahiptir, ancak dezavantajlar\u0131 d\u00fc\u015f\u00fck \u00e7\u0131kt\u0131, y\u00fcksek maliyet ve karma\u015f\u0131k i\u015flemdir; fiziksel k\u0131rma y\u00f6ntemi, malzemeyi mekanik kuvvetle ezmektir.
\nMekanik k\u0131rman\u0131n avantajlar\u0131, b\u00fcy\u00fck \u00e7\u0131kt\u0131, d\u00fc\u015f\u00fck maliyet ve b\u00fcy\u00fck \u00f6l\u00e7ekli end\u00fcstriyel \u00fcretime uygun olan basit i\u015flemdir. Ayr\u0131ca, k\u0131rma i\u015flemi s\u0131ras\u0131nda tozun aktivitesini art\u0131rabilen mekanokimyasal etki \u00fcretilir. Bunlar aras\u0131nda, b\u00fcy\u00fck \u00f6l\u00e7ekli end\u00fcstriyel \u00fcretime uygulanabilen bilyal\u0131 de\u011firmen ile birlikte silindir pres kullan\u0131l\u0131r ve \u00fcr\u00fcn par\u00e7ac\u0131k s\u0131n\u0131fland\u0131rmas\u0131 iyidir ve aktivite y\u00fcksektir. Hava ak\u0131\u015fl\u0131 de\u011firmen, daha iyi \u00fcr\u00fcn performans\u0131 nedeniyle baz\u0131 \u00f6zel alanlarda da yayg\u0131n olarak kullan\u0131lmaktad\u0131r.<\/p>\n
Ultra ince tozlar\u0131n s\u0131n\u0131fland\u0131r\u0131lmas\u0131, santrif\u00fcj kuvveti, yer \u00e7ekimi, atalet kuvveti vb. etkisi alt\u0131nda ortamda farkl\u0131 par\u00e7ac\u0131k boyutlar\u0131ndaki par\u00e7ac\u0131klar\u0131n farkl\u0131 hareket y\u00f6r\u00fcngelerine dayan\u0131r, b\u00f6ylece farkl\u0131 par\u00e7ac\u0131k boyutlar\u0131ndaki par\u00e7ac\u0131klar\u0131n ayr\u0131lmas\u0131 sa\u011flan\u0131r ve ilgili toplama cihazlar\u0131na girer.
\nUltra ince tozla\u015ft\u0131rma i\u00e7in tozla\u015ft\u0131rma ekipman\u0131 kullan\u0131ld\u0131\u011f\u0131nda, farkl\u0131 par\u00e7ac\u0131klar \u00fczerinde etkili olan kuvvetler tekd\u00fcze de\u011fildir ve genellikle tozun yaln\u0131zca bir k\u0131sm\u0131 par\u00e7ac\u0131k boyutu gereksinimlerini kar\u015f\u0131lar. Gereksinimleri kar\u015f\u0131layan \u00fcr\u00fcnler zaman\u0131nda ayr\u0131lamazlarsa, malzemeler a\u015f\u0131r\u0131 ezilir ve tozun bu k\u0131sm\u0131 da k\u00fc\u00e7\u00fck par\u00e7ac\u0131k boyutu nedeniyle k\u00fcmelenir ve b\u00f6ylece tozla\u015ft\u0131rma verimlili\u011fi d\u00fc\u015fer. Bu nedenle, ezilmi\u015f \u00fcr\u00fcnleri etkili bir \u015fekilde s\u0131n\u0131fland\u0131rmak i\u00e7in ultra ince s\u0131n\u0131fland\u0131r\u0131c\u0131lar\u0131n zaman\u0131nda kullan\u0131lmas\u0131, malzemelerin a\u015f\u0131r\u0131 ezilmesini \u00f6nleyebilir, tozla\u015ft\u0131rma verimlili\u011fini art\u0131rabilir ve enerji t\u00fcketimini azaltabilir. Ultra ince s\u0131n\u0131fland\u0131rma, kullan\u0131lan farkl\u0131 ortamlara g\u00f6re genellikle kuru ve \u0131slak tiplere ayr\u0131l\u0131r. Islak s\u0131n\u0131fland\u0131rma, y\u00fcksek s\u0131n\u0131fland\u0131rma do\u011frulu\u011fu ve iyi tekd\u00fczelik ile dispersiyon ortam\u0131 olarak s\u0131v\u0131 kullan\u0131r. Ancak \u0131slak s\u0131n\u0131fland\u0131rma, kurutma ve at\u0131k su ar\u0131t\u0131m\u0131 gibi bir dizi sonraki i\u015fletme sorununa sahiptir ve bu da geli\u015fimini s\u0131n\u0131rlar. Kuru s\u0131n\u0131fland\u0131rma, tozlar\u0131 yer\u00e7ekimi alan\u0131, eylemsizlik kuvveti alan\u0131 veya santrif\u00fcj kuvveti alan\u0131, \u00e7o\u011funlukla pn\u00f6matik s\u0131n\u0131fland\u0131rmaya g\u00f6re s\u0131n\u0131fland\u0131rmakt\u0131r.
