Kev muag khoom ntawm polyamide 66 gf 66 nylon 6 resin yas raw khoom pa66 hais

PA66 Yas muaj qhov tseem ceeb melting taw rau hauv cov ntaub ntawv polyamide. Nws yog ib nrab-crystalline cov khoom siv crystalline. PA66 kuj tswj hwm lub zog muaj zog thiab txhav ntawm qhov kub siab dua. Pa66 Yas Tseem Helgroscopic tom qab molding, qhov uas nyob ntawm feem ntau ntawm cov khoom muaj pes tsawg leeg, cov huab cua thickness, thiab ib puag ncig cov xwm txheej. Hauv cov qauv tsim, cov txiaj ntsig ntawm kev hygroscopicity ntawm cov duab geometric yuav tsum tau txiav txim siab. Txhawm rau txhim kho cov khoom siv tshuab hluav taws xob ntawm pa66, ntau yam hloov kho cov qauv feem ntau ntxiv. Iav yog cov roj ntxiv ntau dua, thiab qee zaum cov roj hmab hluavtaws hluavtaws ntxiv txhawm rau txhim kho kev cuam tshuam. Pa66 Yas yog tsawg dua viscous thiab thiaj li ntws zoo (tab sis tsis zoo li PA6). Cov cuab yeej no tuaj yeem siv los ua cov txheej txheem nyias nyias. Nws viscosity yog rhiab rau qhov kub hloov. Qhov kev xav txog Pa66 yog nruab nrab ntawm 1% thiab 2%. Ntxiv cov iav Fiber ntau ntxiv tuaj yeem txo qis shrinkage tus nqi mus rau 0.2% rau 1%. Qhov sib txawv hauv shrinkage nyob rau hauv qhov ntws kev taw qhia thiab cov kev taw thaiv perpendicular rau cov kev taw qhia ntws loj dua.
