PA6 yog dab tsi? PA6, lub npe hu ua polycaprolactam (Polyamide 6), yog ib hom kev lag luam yas, tseem hu ua nylon 6.Nyob hauv tsab xov xwm no, peb yuav txheeb xyuas kom meej cov muaj pes tsawg leeg, cov khoom, kev siv, nrog rau qhov zoo thiab qhov tsis zoo ntawm PA6, los pab cov neeg nyeem kom nkag siab zoo txog cov yam ntxwv thiab siv cov khoom siv no.
PA6 muaj pes tsawg leeg thiab txheej txheem ntau lawm
PA6 yog cov thermoplastic ua los ntawm lub nplhaib-qhib polymerisation cov tshuaj tiv thaiv ntawm caprolactam. Caprolactam yog ib qho monomer tau los ntawm cov tshuaj tiv thaiv ntawm cov ntaub ntawv raw xws li adipic acid thiab caprolactic anhydride, uas tsim cov saw hlau ntev los ntawm cov tshuaj tiv thaiv polymerization. Cov khoom no muaj qib siab ntawm crystallinity thiab yog li nthuav tawm cov khoom zoo heev thiab tshuaj lom neeg ruaj khov.
Kev ua tau zoo ntawm PA6
PA6 muaj ntau yam khoom zoo heev uas ua rau nws nyiam cov khoom siv engineering.PA6 muaj lub zog siab thiab tawv thiab muaj peev xwm tiv taus cov neeg kho tshuab kev ntxhov siab.PA6 kuj muaj kev puas tsuaj thiab qaug zog, uas ua rau nws tsim nyog rau kev tsim cov khoom uas yuav tsum tau ua haujlwm ntev.PA6 kuj muaj cov tshuaj tiv thaiv zoo rau roj thiab roj, alkalis, thiab ntau yam kev siv hauv kev lag luam. tshuab.
Kev siv PA6
PA6 yog siv nyob rau hauv ntau hom kev lag luam. Nws cov khoom siv kho tshuab zoo heev ua rau nws zoo tagnrho rau kev tsim cov khoom siv kho tshuab xws li iav, bearings, thiab swb. Vim nws txoj kev ua haujlwm siab, PA6 kuj tau siv dav hauv kev tsim cov tsheb xws li roj tso tsheb hlau luam, radiator grills thiab lub qhov rooj tuav, thiab lwm yam.
Qhov zoo thiab qhov tsis zoo ntawm PA6
Txawm hais tias nws muaj ntau qhov zoo, PA6 muaj qee qhov tsis zoo.PA6 muaj qib siab ntawm hygroscopicity, uas ua rau nws muaj kev cuam tshuam rau absorbing noo noo thaum siv nyob rau hauv ib puag ncig ntub, ua rau txo qis ntawm cov khoom siv kho tshuab. Cov yam ntxwv no tuaj yeem txwv nws daim ntawv thov hauv qee qhov chaw tshwj xeeb. Piv nrog rau lwm cov khoom siv hluav taws xob ua haujlwm siab, PA6 muaj cov cua kub tsis tshua muaj zog thiab feem ntau tsuas yog siv tau rau lub sijhawm ntev hauv qhov kub thiab txias hauv qab 80 ° C.
Kev hloov kho ntawm PA6 thiab kev txhim kho yav tom ntej
Txhawm rau kov yeej PA6's qhov tsis txaus, cov kws tshawb fawb tau txhim kho nws qhov kev ua tau zoo los ntawm kev hloov kho cov txheej txheem. Piv txwv li, los ntawm kev ntxiv cov iav fibers los yog lwm yam fillers, rigidity thiab seem stability ntawm PA6 tuaj yeem txhim kho tau zoo, yog li nthuav nws cov kev siv ntau yam. Raws li kev siv thev naus laus zis, PA6 yuav tsum ua lub luag haujlwm tseem ceeb hauv ntau thaj chaw yav tom ntej.
Cov ntsiab lus
PA6 khoom yog dab tsi? Raws li tuaj yeem pom los ntawm kev txheeb xyuas saum toj no, PA6 yog cov khoom siv hluav taws xob ntau yam nrog cov khoom siv zoo heev thiab tshuaj lom neeg. Nws kuj muaj qhov tsis zoo xws li kev nqus noo noo siab thiab tsis muaj cua sov ua haujlwm. Los ntawm kev hloov kho thev naus laus zis, thaj chaw thov ntawm PA6 tau nthuav dav. Txawm hais tias hauv kev lag luam tsheb, kev tsim khoom siv tshuab, lossis hauv kev lag luam hluav taws xob thiab hluav taws xob, PA6 tau pom muaj peev xwm zoo rau kev thov.
