Qhov sib ntxiv ntawm calcium carbonate muab tub lim masterbatch yuav ua rau lub tiaj 76 txhob lo lo ntxhuav opaque thiab ua milky dawb. Tab sis ntxiv tsawg dua yog tus neeg sawv cev nucleating. Lub hom phiaj ntawm kev ntxiv cov nucleating tus neeg sawv cev rau cov yas braiding raw khoom yog ua kom lub nucleation chaw, kom lub nucleation qhov chaw ntawm spherulites thaum lub polypropylene crystallized ua me, thiab cov spherulites raug yuam kom tsim zoo heev spherulites, thiab lub teeb. transmittance yog kho kom zoo.
Kev sib raug zoo ntawm tus nqi ntawm calcium carbonate filling masterbatch thiab lub teeb transmittance yog qhia nyob rau hauv daim duab 3-2. Calcium carbonate masterbatch nrog cov khoom zoo thiab zoo particle loj yuav tsum tau xaiv.
Tsis tas li ntawd, ob lub ntsiab lus yuav tsum tau them sai sai rau hauv kev ua haujlwm:
① Cov dej txias txias ntawm cov yeeb yaj kiab yuav tsum tsawg li sai tau, qhov txias txias yuav tsum ceev (nce qhov nrawm nrawm), thiab crystallinity yuav tsum qis, kom cov iav siv lead ua me me thiab lub teeb xa hluav taws xob yuav raug txhim kho;
② Cov qauv kev sib piv tsis tuaj yeem loj los txo qhov cuam tshuam ntawm lub teeb.
