YIHOO PA (polyamide) polymerization & kev hloov kho ntxiv
Polyamide (tseem hu ua PA lossis Nylon) yog cov ntsiab lus dav dav ntawm cov thermoplastic cob, uas muaj cov pab pawg amide rov ua dua ntawm cov saw hlau loj. PA suav nrog aliphatic PA, aliphatic - muaj ntxhiab PA thiab ntxhiab PA, uas aliphatic PA, tau los ntawm tus naj npawb ntawm cov pa roj carbon atoms hauv cov khoom siv hluavtaws monomer, muaj ntau yam ntau yam, muaj peev xwm tshaj plaws thiab siv tau dav.
Nrog rau cov tsheb me me, kev ua haujlwm siab ntawm cov cuab yeej siv hluav taws xob thiab hluav taws xob, thiab ua kom nrawm ntawm cov txheej txheem hnyav ntawm cov cuab yeej siv tshuab, qhov xav tau ntawm nylon yuav siab dua thiab ntau dua. Nylon qhov tsis txaus tseem yog qhov tseem ceeb txwv nws daim ntawv thov, tshwj xeeb tshaj yog rau PA6 thiab PA66, piv nrog PA46, PA12 ntau yam, muaj tus nqi muaj txiaj ntsig zoo, txawm hais tias qee qhov kev ua tau zoo tsis tuaj yeem ua tau raws li qhov xav tau ntawm kev txhim kho kev lag luam cuam tshuam.
