Cov khoom tseem ceeb ntawm cov fillers

Cov yam ntxwv tseem ceeb ntawm fillers hais txog cov yam ntxwv uas muaj feem cuam tshuam loj tshaj plaws ntawm kev ua haujlwm ntawm cov khoom ntim thiab cov khoom sib xyaw tsim los ntawm cov muab tub lim hauv daim ntawv thov, thiab ua lub luag haujlwm tseem ceeb.
A Cov yam ntxwv zoo thiab qhov loj ntawm cov khoom: cov khoom yog qhov yooj yim ntawm cov khoom ntim, thiab cov duab thiab qhov loj ntawm cov khoom yog qhov tseem ceeb ntawm cov khoom. Cov duab ntawm cov khoom muaj xws li spheres, cubes, blocks, flakes, fibers, thiab lwm yam, thiab qhov luaj li cas ntawm cov particle loj yog txhais los ntawm qhov sib npaug spherical txoj kab uas hla;
B Particle loj tis: lub muab tub lim nws tus kheej yog ib tug aggregate ntawm hais, thiab nws yog tsis yooj yim sua los ua ib tug aggregate ntawm hais me me. Nws tau muab qhab nia los ntawm kev tshuaj ntsuam thiab qee feem raug tshem tawm. Particle loj tis yog ib qho tseem ceeb ntawm cov khoom muab tub lim, feem ntau yog sawv cev los ntawm ib tug particle faib nkhaus, uas ncaj qha cuam tshuam rau nws rheological zog, hnav tsis kam, particle stacking thiab lwm yam khoom;
C Cov cheeb tsam tshwj xeeb thiab qhov chaw tsis muaj zog ntawm cov khoom: Cov cheeb tsam tshwj xeeb yog thaj tsam ntawm ib chav tsev loj ntawm cov muab tub lim, qhia hauv m / g. Nws tus nqi loj qhia tau hais tias qhov chaw sib cuag tau muab los ntawm cov muab tub lim yog loj, uas muaj peev xwm adsorption thiab tshuaj lom neeg muaj peev xwm ntawm cov muab tub lim, qhia tias muaj ntau lub sijhawm rau kev sib cuag; nto dawb lub zog hais txog cov dispersion ntawm cov khoom muab tub lim hauv cov ntaub ntawv ua kua. Los yog thaum cov kua infiltrates cov muab tub lim, nws yuav tsum kov yeej lub zog barrier nyob rau hauv lub contact nto vim hais tias lub cohesive quab yuam ntawm cov molecules yog ntau tshaj qhov attraction ntawm ob yam sib txawv Cheebtsam. Nws tus nqi yog cuam tshuam rau thaj chaw tshwj xeeb thiab muaj pes tsawg leeg ntawm cov muab tub lim, thiab ncaj qha cuam tshuam rau kev tawg ntawm cov muab tub lim hauv cov khoom siv polymer;
D Particle packing ceev: yog hais txog lub ntim ntim los ntawm qee qhov loj ntawm cov muab tub lim, uas cuam tshuam ncaj qha rau qhov zoo thiab ua haujlwm ntawm cov khoom ntim;
E Chemical composition of muab tub lim: sawv cev rau cov qauv tshuaj ntawm cov muab tub lim. Ob lub fillers nrog tib lub Cheebtsam qhia kev sib txawv tom qab sau, uas qhia tau hais tias cov tshuaj muaj pes tsawg leeg ntawm cov muab tub lim tsis tuaj yeem sawv cev rau nws qhov kev ua tau zoo. Lwm yam khoom xws li particle loj thiab particle tis kuj tseem muaj feem cuam tshuam rau cov nyhuv filling.
