Plastik takviye modifikasyonu, \u00f6zellikle otomotiv ve beyaz e\u015fya end\u00fcstrilerinde polipropilen modifikasyonu i\u00e7in talk\u0131n \u00f6nemli bir uygulama alan\u0131d\u0131r.

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
