Kev sib piv cov yam ntxwv
Thaum tshav kub kub Resistance thiab Mechanical Strength
1. PA66 masterbatch nthuav tawm qhov ua kom sov zoo dua li PA6 masterbatch, nrog cov ntsiab lus melting ntau dua (PA66 kwv yees li 260-270 degree, PA6 kwv yees li 210-220 degree). Nws tuav cov xim zoo dua thiab muaj zog txhua yam nyob rau hauv siab - qhov kub thiab txias, ua rau nws haum rau siab - kub daim ntawv thov xws li cav qhov chaw. PA6 masterbatch, ntawm qhov tod tes, muaj qhov toughness zoo dua thiab muaj kev cuam tshuam, tab sis qis qis qis rau ntev -lub sij hawm siv kub.
2. Hygroscopicity thiab Dimensional Stability
PA6 masterbatch yog hygroscopic heev, ua rau nws raug rau qhov kev hloov pauv vim qhov av noo ib puag ncig; noo noo- ntsuas pov thawj yuav tsum tau txiav txim siab hauv kev tsim. PA66 masterbatch muaj qhov qis hygroscopicity, tab sis muaj zog intermolecular rog ua rau muaj kev ruaj ntseg zoo tag nrho.
Ua Tshuab Qhov Sib Txawv
Kev ua haujlwm nyuaj: PA6 masterbatch muaj cov dej ntws zoo thiab kev ua haujlwm kub ntau, yuav tsum muaj cov khoom siv tsis tshua zoo thiab tsim nyog rau cov txheej txheem xws li kev txhaj tshuaj molding thiab extrusion. PA66 masterbatch muaj ntau dua yaj viscosity, yuav tsum tau kub thiab siab zog, thiab xav tau cov khoom nruj dua precision thiab cov txheej txheem tswj.
Moulding Shrinkage: PA6 masterbatch muaj tus nqi qis dua (kwv yees li 1%–1.5%), yuav tsum tau txhim kho los ntawm cov khoom siv ntxiv lossis cov txheej txheem sib xyaw; PA66 masterbatch muaj qhov txo qis qis, tab sis yuav tsum tau tsim lub rooj vag meej ntau dua kom tsis txhob muaj qhov ua tiav ntxov.
Cov cheeb tsam thov thiab cov nqi
1. Cov xwm txheej ntawm daim ntawv thov
PA6 Masterbatch: Feem ntau siv nyob rau hauv cov cheeb tsam uas muaj zog qis dua, xws li cov khoom siv hauv tsev, lub teeb tsheb loj, thiab cov khoom siv fiber ntau.
PA66 Masterbatch: Ua kom pom tseeb hauv siab - qhov yuav tsum tau muaj, xws li cov khoom siv tshuab, cov khoom siv hauv tsheb, thiab siab -kawg hluav taws xob casings.
2. Tus nqi
PA66 masterbatch feem ntau yog 30% -50% kim dua PA6 masterbatch vim qhov tsis txaus ntawm nws cov ntaub ntawv raw (xws li adiponitrile) thiab qhov nyuaj ntawm nws cov txheej txheem. Cov nqi yuav tsum raug ntsuas raws li cov khoom yuav tsum tau ua.
