Nws lub flash point yog kwv yees li 100 ° C, ua raws li cov qauv kev nyab xeeb hauv kev lag luam. Hauv cov nqe lus ntawm cov qauv molecular, nws ob pawg hydroxyl tseem ceeb thiab cov pawg methyl sab muab nws nrog kev ua haujlwm yooj yim. Nws tuaj yeem koom nrog ntau yam tshuaj lom neeg xws li esterification thiab acetalization los ua cov khoom siv polymer sib txawv. Cov txheej txheem tshuaj tiv thaiv yog qhov tsis hnyav thiab tswj tau yam tsis tsim cov tshuaj lom neeg ntau, sib npaug kev ua tau zoo thiab kev phooj ywg ib puag ncig - qhov no yog nws qhov zoo dua li cov khoom siv tshuaj zoo sib xws.
Vim nws cov khoom siv lub cev thiab tshuaj zoo heev, methyl propanol siv tau ntau yam kev siv hauv kev lag luam thiab cov khoom siv pej xeem. Hauv kev lag luam polymer, nws yog cov khoom siv tseem ceeb rau kev tsim cov polyester thiab polyurethane. Thaum siv rau hauv kev tsim cov khoom siv, nws tuaj yeem txhim kho qhov yooj ywm, tiv taus huab cua thiab tiv taus qhov kub qis ntawm cov khoom, txo cov khoom siv viscosity, thiab ua kom cov txheej txheem tiav thiab cov resins du thiab ruaj khov dua. Nws yog siv dav hauv kev tsim khoom thiab kev tsim cov txheej txheem kev lag luam, cov yas engineering thiab elastomers. Tsis tas li ntawd, nws tuaj yeem siv los npaj cov khoom siv yas xws li cov yas thiab cov tshuaj antioxidants, txuas ntxiv lub neej kev pabcuam thiab ua kom zoo dua cov qauv ntawm cov khoom yas.
Hauv kev lag luam tshuaj lom neeg zoo thiab kev lag luam tshuaj txhua hnub, methyl propanol ua haujlwm ua cov kuab tshuaj zoo thiab cov dej noo zoo rau ib puag ncig. Ua tsaug rau nws cov khoom mos, tsis muaj tshuaj lom thiab hydrophilic, nws feem ntau ntxiv rau hauv kev saib xyuas tawv nqaij thiab cov khoom siv pleev kom noo noo rau tawv nqaij, kho cov mis thiab txhim kho kev xav ntawm tawv nqaij yam tsis ua rau khaus tawv nqaij. Ntxiv mus, nws siv tau rau kev npaj cov mis ntawm cov kua mem, cov nplaum thiab cov neeg sawv cev ntxuav, uas tuaj yeem txhim kho kev nplaum thiab kev sib xws ntawm cov khoom, txo qhov volatilization ntawm cov tshuaj lom, txhim kho qib kev tiv thaiv ib puag ncig ntawm cov khoom tiav, thiab hloov kho rau ntau qhov xwm txheej xws li kho kom zoo nkauj hauv tsev, ntawv sau thiab kev lag luam teeb pom kev zoo.
Txawm hais tias methyl propanol yog cov khoom siv tshuaj lom neeg uas muaj kev pheej hmoo tsawg nrog kev ua haujlwm nyab xeeb siab, cov qauv txheem tseem xav tau rau kev siv txhua hnub thiab khaws cia. Cov khoom tiav lawm uas muaj methyl propanol muaj kev nyab xeeb rau kev sib cuag ib txwm tsis muaj kev txhawj xeeb ntau dhau. Cov methyl propanol ntshiab yuav tsum tau khaws cia rau hauv qhov chaw txias thiab cua nkag, deb ntawm qhov kub thiab txias thiab nplaim taws qhib, thiab sib cais ntawm cov tshuaj oxidants muaj zog. Hauv kev ua haujlwm hauv kev lag luam, yuav tsum tau ua cov kev ntsuas tiv thaiv ib txwm kom tsis txhob muaj kev sib cuag ntev thiab kev noj tsis raug. Cov lus qhia ua haujlwm tshuaj lom neeg yooj yim tuaj yeem zam kev pheej hmoo kev nyab xeeb.
Nrog rau kev nrov npe ntawm lub tswv yim tshuaj ntsuab, cov khoom siv tshuaj lom neeg tsis muaj tshuaj lom, ruaj khov thiab ua haujlwm tau zoo tau dhau los ua lub hauv paus ntawm kev txhim kho kev lag luam. Nrog rau cov thev naus laus zis tsim khoom tiav, kev ua haujlwm ruaj khov, kev phooj ywg ib puag ncig thiab kev nyab xeeb, methyl propanol tau maj mam hloov qee cov cawv uas muaj kuab paug siab thiab muaj kev pheej hmoo siab, nrog rau nws qhov kev siv lag luam txuas ntxiv nthuav dav. Nws tus nqi tau raug tshawb nrhiav tas li hauv kev tsim khoom lag luam ib txwm muaj, kev lag luam tshuaj zoo thiab kev lag luam tshuaj ntsuab txhua hnub.
Xaus lus, txawm hais tias zoo li tsis tshua muaj neeg paub, methyl propanol yog ib yam khoom siv tseem ceeb uas tsis tau pom dua hauv kev lag luam niaj hnub no. Nrog kev ua haujlwm ruaj khov thiab kev hloov pauv dav dav, nws nkag mus rau txhua lub ces kaum ntawm peb lub neej, ua kom cov khoom zoo thiab cov neeg lub neej zoo dua. Kev nkag siab txog methyl propanol tsis yog tsuas yog lees paub cov tshuaj lom neeg xwb, tab sis kuj pom qhov zoo nkauj ntawm cov tshuaj lom neeg niaj hnub uas ua haujlwm thiab koom ua ke nrog lub neej txhua hnub.
