Polyhere AminePuas yog ib qho tseem ceeb tshaj plaws hauv kev lag luam tshuaj lom neeg vim nws cov kev siv thiab kev ua tau zoo sib xws ntawm kev hloov pauv thiab cuam tshuam. Nws yog dav siv raws li tus neeg kho tus neeg sawv cev, saw txuas, thiab ua kom hloov kho cov hloov kho hauv polymer. Txoj kev polyether hoine yog siv feem ntau nyob ntawm nws cov qauv molecular, kev ua haujlwm, thiab kev sib haum xeeb, thiab kev sib haum xeeb nrog lwm cov.
Hauv kev lag luam polyurethane, polyhers amine yog siv los ua ob qho hloov tau thiab cov tshuab tsis sib haum. Thaum siv los ua cov saw txuas, nws cuam tshuam nrog isocyanates los ua polyurea lossis polyurethans network uas ua rau muaj kev sib zog ua kom zoo, zoo siv zog, thiab muaj zog. Qhov no ua rau nws haum rau cov khoom lag luam xws li cov tshuaj pleev xim dej, muaj cov foob pob, thiab elastomeric flooring. Nws cov ceev ceev ceev pab txuag hluav taws xob ua kom zoo rau-} chaw seem txau cov ntawv thov, uas yog ib qho ntawm cov txiaj ntsig polyether yog kev nyiam ua niaj hnub.
Nyob rau epoxy cob cov tshuab, polyhers amine pab ua tus kho tus neeg sawv cev los tsim cov nqaij nyuj thiab cov nplaum nplaum nrog cov khoom nplaum tshwj xeeb, thiab xim ruaj khov. Piv nrog cov tsoos amine caping cov neeg sawv cev, polyether amine ua tau qis {{ Lub txheej txheem txheej txheem yog siv dav hauv kev tiv thaiv marine, txuas hniav, raj dej, thiab cov plag tsev.
Tshaj dhau cov polymers, cov khoom qab zib polyether kuj pom cov ntawv thov hauv cov roj ntxiv cov haujlwm. Nws cov qauv molecular tso cai rau nws kom huv cav tshuab los ntawm kev tshem tawm cov carbon tso nyiaj thiab txhim kho cov roj kev lag luam. Nyob rau hauv cov roj nplua mias, nws ua raws li cov dispersant uas ua rau impurities raug tshem tawm, txo kev hnav, txo lub neej lub neej.
Nyob rau hauv cov ntaub ntawv sib xyaw, cov khoom qab zib polyether txhim kho lub zog thiab nkees ua rau muaj zog, ua rau nws haum rau cov cua tshuab, thiab lub teeb yuag qauv. Hauv cov nplaum thiab cov kaub puab, nws thiaj li ua tau raws li cov hlau, ua vaj tse, muab cov yas ua kom sov, muab cov lus ntev}}}}} dur dur dur conditions conditions under environmentອກ.
Qhov zoo ntawm kev siv polyether amine suav nrog cov reactivity siab, kev nruj heev, tsawg toxicity, thiab cond compatibility. Nws ua rau tsim cov ntaub ntawv siab tshaj plaws uas tau ua raws li qhov kev thov loj hlob, hloov tau yooj yim, thiab kev ruaj khov. Raws li kev lag luam txuas ntxiv mus ua raws siab - {{{{{{{{{{{{{{{{{{}} {{{{{
