Hardener , (los yog activator raws li nws paub nyob rau hauv lub lag luam) drys lub pleev xim los ntawm chemically cross-linking cov pleev xim mus rau hauv hardener , ua ib qho urethane mix uas yog ntau impervious rau tshuaj tua kab mob. Xim yuav tsis kho tag nrho yog tias nws tsis qhib.
Ib tug kuj yuav nug, lub ntsiab lus ntawm hardener yog dab tsi? Lub ntsiab lus ntawm hardener .: ib qho uas hardens tshwj xeeb tshaj yog: ib yam khoom ntxiv (raws li rau xim los yog kua roj vanish) kom tawv nqaij.
Ib yam li ntawd, hardener yog dab tsi?
Polyamine hardeners yog ua nce ntawm cov organic molecule uas muaj ob lossis ntau pawg amine. Lwm hom hardeners suav nrog polyamide hardeners thiab anhydride hardeners , txawm hais tias cov hom no tsuas yog ua kom sov.
Puas yog Catalyst yog ib qho hardener?
Tag nrho cov resins suav nrog GelCoat, PoolCoat thiab FlowCoats yuav tsum tau catalyzed nrog catalyst los yog hardener ua ntej siv rau cov tshuaj tiv thaiv kom pib tig cov resin los ntawm cov kua rau ib qho khoom, un-catalyzed resin tsuas yuav tsis tawv. Catalysts yog corrosive thiab yuav tsum tau saib xyuas tshwj xeeb.

Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
