Qhov sib txawv loj ntawm polyamide thiab polyimide yog nyob rau hauv lawv cov qauv tshuaj; polyamide muaj cov amide (-CONH-) linkages nyob rau hauv lawv cov pob txha polymer, thaum polyimide muaj imide pawg (-CO-N-OC-) nyob rau hauv lawv cov pob txha polymer.
Cov khoom siv dab tsi yog polyimide?
Polyimide (qee lub sijhawm luv luv PI) yog a polymer ntawm imide monomers koom nrog hauv chav kawm ntawm cov khoom siv siab ua haujlwmNrog lawv cov cua sov-ua haujlwm, polyimides nyiam ntau daim ntawv thov hauv lub luag haujlwm xav tau rugged organic cov ntaub ntawv, e.g. kub kub roj hlwb, qhia, thiab ntau yam tub rog lub luag hauj lwm.
Dab tsi yog polyamide tseem hu ua?
High molecular hnyav polyamides feem ntau hu ua nylon. Polyamides yog crystalline polymers feem ntau tsim los ntawm condensation ntawm diacid thiab diamine.
Qhov twg hauv qab no yog polyimide?
Nylon-66 yog polyamide ntawm hexamethylene diamine (CH2)6(NH2)2 thiab adipic acid (CH2)4(COOH)2.
polyamide siv rau dab tsi?
Polyamide muaj ntau hauv textiles xws li khaub ncaws thiab ntaub pua plag. Nws kuj tseem muaj ntau yam hauv kev tsim cov khoom uas yuav tsum tau muaj zog thiab yoog raws, nrog rau cov kab nuv ntses, cov khoom siv hluav taws xob, lub zog, cov khoom siv guitar thiab cov hlua thiab cov khoom siv kho mob.
