Polilaktik asit, ekstraksiyon, kimyasal polimerizasyon ve di\u011fer i\u015flemler yoluyla yenilenebilir kaynaklardan elde edilen y\u00fcksek molek\u00fcler bir polimerdir. Biyobozunurluk ve biyouyumlulu\u011fa sahiptir. Tamamen karbondioksit ve suya ayr\u0131\u015f\u0131r. Polilaktik asit kullan\u0131m\u0131 ve te\u015fviki, petrol kaynaklar\u0131n\u0131n t\u00fcketimini azaltabilir ve \u00e7evre koruma i\u00e7in b\u00fcy\u00fck \u00f6nem ta\u015f\u0131yan enerji tasarrufu ve emisyon azaltmada rol oynayabilir.<\/p>\n

Polilaktik asit, y\u00fcksek mukavemete, y\u00fcksek mod\u00fcle ve iyi \u015feffafl\u0131\u011fa ve hava ge\u00e7irgenli\u011fine sahiptir, ancak i\u015fleme s\u0131ras\u0131nda kristalle\u015fme h\u0131z\u0131 \u00e7ok yava\u015ft\u0131r, bu da uzun i\u015flem d\u00f6ng\u00fcs\u00fcne ve polilaktik asit \u00fcr\u00fcnlerinin uygulama alanlar\u0131n\u0131 b\u00fcy\u00fck \u00f6l\u00e7\u00fcde s\u0131n\u0131rlayan zay\u0131f \u0131s\u0131 direncine neden olur.<\/p>\n

\u015eu anda, polilaktik asidin performans\u0131n\u0131 iyile\u015ftirmenin en yayg\u0131n yolu, bir \u00e7ekirdekle\u015ftirici ajan eklemektir. Ger\u00e7ek kurumsal i\u015fleme uygulamalar\u0131nda, talk tozu, polilaktik asidin gerilmesini, b\u00fck\u00fclmesini vb. iyile\u015ftirebilen, polilaktik asit i\u00e7in en yayg\u0131n kullan\u0131lan inorganik \u00e7ekirdekle\u015ftirici ajand\u0131r. Mekanik \u00f6zellikler, \u0131s\u0131 direncini artt\u0131r\u0131r.<\/p>\n

Farkl\u0131 talk tozu i\u00e7eriklerinin \u00e7ok parlak saf polilaktik asidin kristalle\u015fme \u00f6zellikleri ve kapsaml\u0131 mekanik \u00f6zellikleri \u00fczerindeki etkilerini inceleyerek, sonu\u00e7lar polilaktik asidin kristalle\u015fme tepe s\u0131cakl\u0131\u011f\u0131n\u0131n talk tozu i\u00e7eri\u011finin artmas\u0131yla ve kristalle\u015fme s\u0131cakl\u0131\u011f\u0131n\u0131n artt\u0131\u011f\u0131n\u0131 g\u00f6stermektedir. b\u00f6lgesi y\u00fcksek s\u0131cakl\u0131k y\u00f6n\u00fcne do\u011fru hareket etmeye devam eder ve kristalle\u015fme h\u0131z\u0131 da h\u0131zlan\u0131r.<\/p>\n
