Talk, yumu\u015fak dokusu ve g\u00fc\u00e7l\u00fc ya\u011fl\u0131 hissi nedeniyle bu ismi alm\u0131\u015ft\u0131r. Katmanl\u0131 bir yap\u0131ya sahip, \u00e7o\u011funlukla magnezyum silikat, al\u00fcminyum oksit, nikel oksit vb. i\u00e7eren hidratl\u0131 bir magnezyum silikat mineralidir.<\/p>\n

Talk, kayganl\u0131k, yap\u0131\u015fmazl\u0131k, ak\u0131\u015fkanl\u0131k, yang\u0131na dayan\u0131kl\u0131l\u0131k, asit direnci, yal\u0131t\u0131m, y\u00fcksek erime noktas\u0131, kimyasal inaktivite, iyi gizleme g\u00fcc\u00fc, yumu\u015fakl\u0131k, iyi parlakl\u0131k, g\u00fc\u00e7l\u00fc adsorpsiyon vb. gibi m\u00fckemmel fiziksel ve kimyasal \u00f6zelliklere sahiptir. Kaplamalarda, boyalarda, plastiklerde, ka\u011f\u0131t yap\u0131m\u0131nda, seramiklerde, kozmetiklerde, ila\u00e7larda, g\u0131dada, g\u00fcnl\u00fck ihtiya\u00e7larda ve di\u011fer end\u00fcstrilerde yayg\u0131n olarak kullan\u0131l\u0131r.<\/p>\n

Talk, plastik \u00fcr\u00fcnlerde en yayg\u0131n kullan\u0131lan inorganik tozlardan biridir. Talk\u0131n plastik \u00fcr\u00fcnlerdeki \u00f6zelli\u011fi, plastik \u00fcr\u00fcnlerin belirli \u00f6zelliklerini \u00f6nemli \u00f6l\u00e7\u00fcde iyile\u015ftirebilmesidir. Bu nedenle, talk se\u00e7erken talk i\u00e7in a\u015fa\u011f\u0131daki gereklilikler de kar\u015f\u0131lanmal\u0131d\u0131r.<\/p>\n

Y\u00fcksek safl\u0131k<\/p>\n

Talk\u0131n safl\u0131\u011f\u0131 ne kadar y\u00fcksekse, g\u00fc\u00e7lendirici etkisi o kadar iyidir. Talktaki di\u011fer mineral<\/a> safs\u0131zl\u0131klar\u0131 aras\u0131nda, metal mineralleri (\u00f6zellikle demir) plastiklerin ya\u015flanma kar\u015f\u0131t\u0131 \u00f6zelli\u011fi \u00fczerinde \u00e7ok belirgin bir etkiye sahiptir.<\/p>\n

Yap\u0131<\/p>\n

Talk genellikle yo\u011fun bloklar, yapraklar, radyaller ve lifler \u015feklindedir. Talk\u0131n kristal yap\u0131s\u0131 katmanl\u0131 oldu\u011fundan, pullara ayr\u0131lma e\u011filimindedir ve \u00f6zel bir kayganl\u0131\u011fa sahiptir.<\/p>\n

Y\u00fcksek kaliteli ultra ince talk pudras\u0131 pullu bir yap\u0131ya sahiptir. Plastik \u00fcr\u00fcnlerde kullan\u0131ld\u0131\u011f\u0131nda, re\u00e7inede katmanl\u0131 bir \u015fekilde e\u015fit \u015fekilde da\u011f\u0131labilir ve re\u00e7ine ile iyi bir uyumlulu\u011fa ve mekanik \u00f6zelliklerin tamamlay\u0131c\u0131l\u0131\u011f\u0131na sahiptir.<\/p>\n

Islak beyazl\u0131k ve renk tonu<\/p>\n

Talk pudras\u0131 ve plastik kar\u0131\u015ft\u0131r\u0131ld\u0131ktan sonra, plasti\u011fin rengi az veya \u00e7ok de\u011fi\u015fir. Koyu renkli plastik \u00fcr\u00fcnler, eklenen talk pudras\u0131n\u0131n beyazl\u0131\u011f\u0131 i\u00e7in \u00e7ok y\u00fcksek gereksinimlere sahip de\u011fildir. Ancak, a\u00e7\u0131k renkli \u00fcr\u00fcnlerin daha iyi renklere sahip olmas\u0131n\u0131 sa\u011flamak i\u00e7in, talk pudras\u0131n\u0131n daha y\u00fcksek bir \u0131slak beyazl\u0131\u011fa ve uygun bir renk tonuna sahip olmas\u0131 gerekir.<\/p>\n

Silisyum dioksit i\u00e7eri\u011fi<\/p>\n

Talk pudras\u0131ndaki silisyum (SiO2) i\u00e7eri\u011fi, talk pudras\u0131n\u0131n derecesini \u00f6l\u00e7mek i\u00e7in \u00f6nemli bir g\u00f6stergedir. Talk pudras\u0131ndaki silisyum i\u00e7eri\u011fi ne kadar y\u00fcksekse, talk pudras\u0131n\u0131n safl\u0131\u011f\u0131 o kadar y\u00fcksek, uygulama etkisi o kadar iyi ve fiyat\u0131 da o kadar y\u00fcksek olur.
\nM\u00fc\u015fterilerin talk pudras\u0131n\u0131 farkl\u0131 plastik \u00fcr\u00fcnlerin performans gereksinimlerine g\u00f6re se\u00e7meleri gerekir. \u00d6rne\u011fin, tar\u0131msal filme eklenen talk pudras\u0131n\u0131n silisyum i\u00e7eri\u011fi daha y\u00fcksek, par\u00e7ac\u0131k boyutu k\u00fc\u00e7\u00fck ve par\u00e7ac\u0131k boyutu da\u011f\u0131l\u0131m\u0131 dar olmal\u0131d\u0131r, b\u00f6ylece filmin \u0131\u015f\u0131k ge\u00e7irgenli\u011fi iyi olur ve filmin \u00e7ekme mukavemeti ve delinme direnci iyile\u015ftirilir.<\/p>\n

Enjeksiyon kal\u0131plama, levhalar ve \u00e7ubuklarda kullan\u0131lan talk pudras\u0131 i\u00e7in, silisyum i\u00e7eri\u011fi gereksiniminin \u00e7ok y\u00fcksek olmas\u0131 gerekmez. Daha d\u00fc\u015f\u00fck silisyum i\u00e7eri\u011fine sahip \u00fcr\u00fcnler sadece daha ucuz olmakla kalmaz, ayn\u0131 zamanda plastik \u00fcr\u00fcnlerin sertli\u011fini ve darbe mukavemetini de iyile\u015ftirebilir.<\/p>\n

Renk<\/p>\n

\u0130\u015flenmemi\u015f talk pudras\u0131 cevherinin renkleri birbirinden farkl\u0131d\u0131r ve beyaz, gri, a\u00e7\u0131k k\u0131rm\u0131z\u0131, pembe, a\u00e7\u0131k mavi, a\u00e7\u0131k ye\u015fil ve di\u011fer renkler olabilir. Talk pudras\u0131 ayr\u0131ca \u00f6zel bir g\u00fcm\u00fc\u015f benzeri veya inci benzeri renge sahiptir ve farkl\u0131 kat\u0131 parlakl\u0131k derecelerine sahiptir. Bu renk, \u00fcr\u00fcn\u00fcn g\u00f6r\u00fcn\u00fcm\u00fcn\u00fc ve g\u00f6rsel etkisini iyile\u015ftirebilir.<\/p>\n

Y\u00fczey \u00f6zellikleri<\/p>\n

Talk pudras\u0131, kayna\u011f\u0131na ba\u011fl\u0131 olarak farkl\u0131 y\u00fczey \u00f6zellikleri sunar. \u00d6zg\u00fcl y\u00fczey alan\u0131 ve ya\u011f emilim oran\u0131 b\u00fcy\u00fck \u00f6l\u00e7\u00fcde mineral<\/a> kaynaklar\u0131 ve \u00fcr\u00fcn inceli\u011fi taraf\u0131ndan belirlenir. Bu \u00f6zellikleri etkileyen di\u011fer fakt\u00f6rler y\u00fczey p\u00fcr\u00fczl\u00fcl\u00fc\u011f\u00fc, par\u00e7ac\u0131k \u015fekli ve g\u00f6zenek hacmidir. Talk pudras\u0131n\u0131n b\u00fcy\u00fck \u00f6zg\u00fcl y\u00fczey alan\u0131 ve g\u00f6r\u00fcn\u00fcm yap\u0131s\u0131 yaln\u0131zca katk\u0131 maddelerinin dozaj\u0131n\u0131 etkilemekle kalmayacak, ayn\u0131 zamanda re\u00e7ine yap\u0131lar\u0131 aras\u0131ndaki ba\u011flanma kuvvetini de art\u0131rarak plastik \u00fcr\u00fcnlerin fiziksel \u00f6zelliklerini iyile\u015ftirecektir.<\/p>\n

Nem<\/p>\n

Talk pudras\u0131n\u0131n yap\u0131sal morfolojisi \u00f6zelliklerini belirler. Talk pudras\u0131 hidrofobik olmas\u0131na ra\u011fmen, par\u00e7ac\u0131k \u015feklinin kenar\u0131n\u0131n d\u00fczensizli\u011fi nedeniyle hem yap\u0131sal su hem de kristal su i\u00e7erir. Bu nedenle talk pudras\u0131n\u0131n nem i\u00e7eri\u011fi kalsiyum karbonattan daha fazlad\u0131r. Nem, plastiklerin performans\u0131n\u0131 kolayca etkileyebilir, bu nedenle talk pudras\u0131ndan nemin uzakla\u015ft\u0131r\u0131lmas\u0131 ve kurutma i\u015flemi olduk\u00e7a de\u011ferli olmal\u0131d\u0131r.<\/p>\n

Statik elektrik<\/p>\n

Talk pudras\u0131 katmanl\u0131 bir yap\u0131ya ve geni\u015f bir \u00f6zg\u00fcl y\u00fczey alan\u0131na sahiptir. Par\u00e7ac\u0131klar\u0131n d\u00fczensiz \u015fekli ve y\u00fczeyin d\u0131\u015fb\u00fckey ve i\u00e7b\u00fckey \u015fekli, b\u00fcy\u00fck bir s\u00fcrt\u00fcnme fakt\u00f6r\u00fcne sahip olmas\u0131n\u0131 ve statik elektri\u011fin kolayca \u00fcretilmesini sa\u011flar, bu da k\u00fc\u00e7\u00fck par\u00e7ac\u0131klar aras\u0131ndaki aglomerasyonun da\u011f\u0131t\u0131lmas\u0131n\u0131 zorla\u015ft\u0131r\u0131r ve uygulama etkisini etkiler.<\/p>\n

Ak\u0131c\u0131l\u0131k<\/p>\n

Ekstr\u00fczyon i\u015flemi s\u0131ras\u0131nda, talk pudras\u0131n\u0131n pullu yap\u0131s\u0131, di\u011fer gran\u00fcler inorganik malzemelere g\u00f6re zay\u0131f ak\u0131\u015fkanl\u0131\u011fa ve da\u011f\u0131lma zorlu\u011funa sahiptir ve ana vida torku b\u00fcy\u00fckt\u00fcr, bu nedenle daha iyi aktivasyon ve kaplama, bu sorunlar\u0131n \u00fcstesinden gelmenin anahtar\u0131d\u0131r.<\/p>\n","protected":false},"excerpt":{"rendered":"
