Hammaddelerin kararl\u0131l\u0131\u011f\u0131<\/p>\n
K\u00fcresel silisyum mikro tozu \u00fcretmek i\u00e7in kullan\u0131lan hammaddeler tercihen ayn\u0131 cevher damar\u0131ndan ve ayn\u0131 \u00fcretim s\u00fcrecinden i\u015flenen a\u00e7\u0131sal silisyum mikro tozudur, b\u00f6ylece hammaddelerin tekd\u00fczeli\u011fi en \u00fcst d\u00fczeye \u00e7\u0131kar\u0131l\u0131r ve k\u00fcreselle\u015ftirme s\u0131cakl\u0131\u011f\u0131, gaz beslemesi, besleme miktar\u0131, bas\u0131n\u00e7, ak\u0131\u015f h\u0131z\u0131 ve di\u011fer fakt\u00f6rlerin de\u011fi\u015fmeden kalmas\u0131 ko\u015fuluyla y\u00fcksek k\u00fcreselle\u015ftirme oran\u0131na sahip \u00fcr\u00fcnlerin \u00fcretilmesi sa\u011flan\u0131r.<\/p>\n
Hammaddelerin fiziksel ve kimyasal g\u00f6stergeleri belirli bir aral\u0131kta kontrol edilmelidir<\/p>\n
Hammaddelerin fiziksel ve kimyasal g\u00f6stergeleri \u00e7ok fazla dalgalan\u0131r, bu sadece k\u00fcreselle\u015ftirme s\u0131cakl\u0131\u011f\u0131n\u0131 etkilemekle kalmaz, ayn\u0131 zamanda k\u00fcrelerin da\u011f\u0131l\u0131m\u0131n\u0131 da etkiler.<\/p>\n

A\u00e7\u0131sal silisyum mikro tozunun, \u00f6zellikle ultra ince a\u00e7\u0131sal silisyum mikro tozunun i\u015flenmesi s\u0131ras\u0131nda, y\u00fczey enerjisinin artmas\u0131 nedeniyle genellikle tozun ikincil aglomerasyonu meydana gelir.<\/p>\n
Hammaddelerin nem i\u00e7eri\u011fi<\/p>\n
K\u00fcresel silisyum mikro tozunun hammaddesi olarak kullan\u0131lan a\u00e7\u0131sal silisyum mikro tozu, uygunsuz koruma, \u00e7ok uzun depolama s\u00fcresi ve a\u015f\u0131r\u0131 \u00e7evre nemi gibi fakt\u00f6rlerden etkilenirse, tozun nemi emmesine, y\u00fcksek nem i\u00e7eri\u011fine sahip olmas\u0131na ve aglomera olmas\u0131na neden olur ve bu da k\u00fcresel silisyum mikro tozunun k\u00fcreselle\u015fme etkisini etkiler.<\/p>\n
Hammaddelerdeki radyoaktif elementler d\u00fc\u015f\u00fck olmal\u0131d\u0131r<\/p>\n
D\u00fc\u015f\u00fck radyasyonlu k\u00fcresel silisyum mikro tozu \u00fcretmek i\u00e7in kullan\u0131lan hammaddeler i\u00e7in, yaln\u0131zca radyasyon elementlerinin kendileri (uranyum U, toryum Th, vb.) \u00e7ok d\u00fc\u015f\u00fck oldu\u011funda \u00fcretilen \u00fcr\u00fcnler d\u00fc\u015f\u00fck radyasyonlu k\u00fcresel silisyum mikro tozunun gereksinimlerini kar\u015f\u0131layabilir.<\/p>\n
K\u00fcresel silikon mikro tozunun y\u00fczey modifikasyonunda iki ba\u011flant\u0131 vard\u0131r. Birincisi, k\u00fcresel silikon mikro tozu hammaddelerinin ikincil k\u00fcmelenmi\u015f par\u00e7ac\u0131klar\u0131n\u0131 da\u011f\u0131tmakt\u0131r – a\u00e7\u0131sal silikon mikro tozu, \u00f6zellikle ultra ince a\u00e7\u0131sal silikon mikro tozu ve k\u00fcreselle\u015ftirmeden \u00f6nce par\u00e7ac\u0131klar\u0131 da\u011f\u0131tmak i\u00e7in \u00f6nce y\u00fczey aktivasyon i\u015flemi ger\u00e7ekle\u015ftirmektir. Bunun i\u00e7in kullan\u0131lan y\u00fczey da\u011f\u0131t\u0131c\u0131n\u0131n y\u00fcksek s\u0131cakl\u0131kta tamamen buharla\u015ft\u0131r\u0131lmas\u0131 gerekir, aksi takdirde k\u00fcresel silikon mikro tozunda karbon birikintilerine neden olur ve \u00fcr\u00fcn kalitesini etkiler.<\/p>\n
\u0130kincisi, k\u00fcresel silikon mikro tozunun ge\u00e7 modifikasyonudur. Silikon mikro tozu inorganik bir dolgu maddesi olarak kullan\u0131ld\u0131\u011f\u0131nda ve organik re\u00e7ine ile kar\u0131\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda, zay\u0131f uyumluluk ve dispersiyon zorlu\u011fu sorunlar\u0131 vard\u0131r, bu da entegre devre ambalaj\u0131 ve alt tabakalar gibi malzemelerin zay\u0131f \u0131s\u0131 direncine ve nem direncine yol a\u00e7ar ve b\u00f6ylece \u00fcr\u00fcn\u00fcn g\u00fcvenilirli\u011fini ve kararl\u0131l\u0131\u011f\u0131n\u0131 etkiler. Silisyum mikrotoz ile organik polimer malzemeler aras\u0131ndaki aray\u00fcz ba\u011flanma sorununu iyile\u015ftirmek ve uygulama performans\u0131n\u0131 art\u0131rmak i\u00e7in genellikle silisyum mikrotozun y\u00fczeyini de\u011fi\u015ftirmek gerekir.<\/p>\n","protected":false},"excerpt":{"rendered":"
