FAQ
Dab tsi ua rau streaking hauv kev txhaj tshuaj molded qhov chaw?
Feem ntau, streaking tshwm sim vim tias cov xim tsis tau nthuav tawm tag nrho, uas ua rau muaj qhov sib txawv ntawm qhov pom tau tias cov molten polymer khiav los ntawm cov pwm. Qee qhov laj thawj feem ntau tsis txaus sib xyaw vim tias cov ntsia hlau nrawm nrawm dhau los yog tsis muaj qhov sib xyaw txaus, nrawm dhau ntawm kev txhaj tshuaj nrawm uas cuam tshuam cov dej ntws thiab kev taw qhia ntawm cov xim, qhov kub tsis zoo uas txwv cov xim los ntawm melting thiab sib tov sib npaug, thiab cov xim sib xyaw ua ke vim tias cov nplaim tsis kho zoo los yog tsis zoo.
Yuav ua li cas cov organic thiab inorganic pigments txawv nyob rau hauv dispersion cwj pwm?
Organic pigments feem ntau muaj cov ntsiab lus me me, qhov loj me me, thiab qhov zoo ntawm qhov chaw uas yuav tsum tau sib xws nrog cov polymers uas tsis yog polar. Lawv muaj cov xim ci ntsa iab thiab meej, tab sis qhov kub thiab txias yuav tsum tau ua tib zoo tswj thaum ua kom lawv tsis txhob tawg. Cov xim inorganic muaj cov khoom loj dua, muaj qhov tshwj xeeb siab dua, thiab zoo dua qhov kub thiab txias los ntawm qhov xwm txheej. Lawv kis tau yooj yim dua nyob rau hauv polar plastics, tab sis koj yuav tsum tau ntxiv ntau ntawm lawv kom tau txais cov xim tib lub zog.
Puas muaj kev cuam tshuam tsis zoo cuam tshuam rau cov khoom siv kho tshuab tshaj li qhov pom?
Tau kawg. Raws li kev ntxhov siab tsim, pigment agglomerates pib tawg mus rau hauv kev thauj khoom thiab txo qhov cuam tshuam lub zog thiab txuas ntxiv thaum so. Thaum cov xim tsis sib kis sib npaug, lawv ua rau muaj qhov sib txawv ntawm crystallinity hauv semi-crystalline plastics. Cov kev sib txawv no tsim cov rog sab hauv uas ua rau muaj kev sib ntaus sib tua thiab qhov tsis txaus ntseeg. Tsis txhob kis cov pa roj carbon dub sib npaug tuaj yeem ua rau nws cov txiaj ntsig zoo, xws li kev tiv thaiv UV, vim tias nws tawm hauv thaj chaw uas tsis tau them txaus qhib rau photodegradation.
