Plastik takviye modifikasyonu, \u00f6zellikle otomotiv ve beyaz e\u015fya end\u00fcstrilerinde polipropilen modifikasyonu i\u00e7in talk\u0131n \u00f6nemli bir uygulama alan\u0131d\u0131r. Talk, \u00fcr\u00fcnlerin \u0131s\u0131l bozulma s\u0131cakl\u0131\u011f\u0131n\u0131 art\u0131rabilir, boyutsal kararl\u0131l\u0131\u011f\u0131 art\u0131rabilir ve kal\u0131p b\u00fcz\u00fclmesini azaltabilir. Ultra ince talk, \u00fcr\u00fcnlerin sertli\u011fini, s\u00fcr\u00fcnme direncini ve darbe dayan\u0131m\u0131n\u0131 art\u0131r\u0131r. Bu nedenle ara\u00e7lar\u0131n i\u00e7 k\u0131s\u0131mlar\u0131n\u0131n, d\u0131\u015f k\u0131s\u0131mlar\u0131n\u0131n ve yap\u0131sal par\u00e7alar\u0131n\u0131n bir\u00e7o\u011fu talk takviyeli modifiye polipropilen malzemeler kullan\u0131r.<\/p>\n

Safl\u0131k, \u00fcr\u00fcn\u00fcn talk i\u00e7eri\u011fini ifade eder. Talkun safl\u0131\u011f\u0131 ne kadar y\u00fcksek olursa, g\u00fc\u00e7lendirici etkisi o kadar iyi olur. Talk safl\u0131\u011f\u0131n\u0131n do\u011frudan \u00f6l\u00e7\u00fcm\u00fc daha karma\u015f\u0131kt\u0131r ve genellikle SiO2 ile ifade edilen 1050 \u00b0C’de ate\u015fleme kayb\u0131 ile tahmin edilebilir. Ate\u015fleme kayb\u0131 ne kadar d\u00fc\u015f\u00fckse, SiO2 de\u011feri o kadar y\u00fcksek ve safl\u0131k o kadar y\u00fcksek olur. Saf talk\u0131n SiO2 i\u00e7eri\u011fi %63.47’dir ve tutu\u015fma kayb\u0131 %4.75’tir. Ate\u015fleme kayb\u0131 <%8.5 olan talk tozunun iyile\u015ftirme ve de\u011fi\u015ftirme etkisi a\u00e7\u0131kt\u0131r; ate\u015fleme kayb\u0131 ile modifikasyonun iyile\u015ftirme etkisi %8.5 ila %16 zay\u0131ft\u0131r;<\/p>\n

Do\u011fal talk, modifikasyon etkisi \u00fczerinde \u00e7e\u015fitli olumsuz etkilere sahip olacak safs\u0131zl\u0131k mineralleri i\u00e7erir. Bu safs\u0131zl\u0131klar \u015funlar\u0131 i\u00e7erir: manyezit, dolomit, klorit, kuvars, demir tuzlar\u0131, a\u011f\u0131r metaller vb.<\/p>\n

\u00c7al\u0131\u015fmalar, farkl\u0131 orijinlerdeki talk safs\u0131zl\u0131klar\u0131n\u0131n t\u00fcrlerinin ve i\u00e7eriklerinin farkl\u0131 oldu\u011funu ve bunlar\u0131n takviye ve modifikasyon \u00fczerindeki etkilerinin de farkl\u0131 oldu\u011funu g\u00f6stermi\u015ftir. Manyezit ve dolomitin e\u011filme mod\u00fcl\u00fc ve termal kararl\u0131l\u0131k \u00fczerinde belirgin olumsuz etkileri vard\u0131r ve klorit de vard\u0131r Olumsuz etkiler manyezit ve dolomitinkinden daha k\u00fc\u00e7\u00fckt\u00fcr; a\u011f\u0131r metaller ve demir tuzlar\u0131, plastiklerin ya\u015flanma kar\u015f\u0131t\u0131 ve termal stabilitesi \u00fczerinde olumsuz etkilere sahiptir; a\u011f\u0131r metallerin etkilerinin farkl\u0131 \u015fekilde i\u015flenmesi gerekir ve talk yap\u0131s\u0131ndaki a\u011f\u0131r metaller karbondakinden daha fazlad\u0131r. Asit tuzlar\u0131ndaki a\u011f\u0131r metaller ve di\u011fer safs\u0131zl\u0131k mineral<\/a> yap\u0131lar\u0131 daha az etkiye sahiptir.<\/p>\n

Bu nedenle, bir talk t\u00fcr\u00fc se\u00e7erken, sadece safl\u0131\u011f\u0131na dikkat etmekle kalmamal\u0131, ayn\u0131 zamanda men\u015fe kayna\u011f\u0131n\u0131 ve i\u00e7indeki safs\u0131zl\u0131klar\u0131n t\u00fcr\u00fcn\u00fc ve i\u00e7eri\u011fini de anlamal\u0131d\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
