2-Methyl-1,3-propanediol CAS: 2163-42-0

2-Methyl-1,3-propanediol siv dav hauv kev tsim cov polyester resins thiab polyurethane cov ntaub ntawv. Ua ib qho tshuaj nruab nrab, nws pab txhawb rau kev tsim cov polymers ua tau zoo uas muaj cov khoom siv kho tshuab zoo heev, tiv taus tshuaj lom neeg, thiab ua haujlwm tau ntev. Cov polymers no siv rau hauv cov txheej, cov nplaum, elastomers, thiab cov fibers, pab txhawb rau kev txhim kho ntawm ntau yam khoom thoob plaws kev lag luam. Ntxiv mus, cov tshuaj no ua haujlwm ua ib qho khoom muaj nqis hauv kev tsim cov khoom siv tu tus kheej thiab cov khoom siv pleev kom zoo nkauj. Nws cov khoom ua kom noo thiab cov kuab tshuaj ua rau nws tsim nyog rau kev siv hauv cov tshuaj pleev tawv nqaij, cov khoom siv tu plaub hau, thiab cov khoom siv tu qhov ncauj. Tsis tas li ntawd, 2-methyl-1,3-propanediol lub luag haujlwm ua cov kuab tshuaj ua rau cov khoom xyaw nquag solubility thiab ruaj khov hauv ntau yam kev npaj pleev kom zoo nkauj. Hauv kev lag luam tshuaj, 2-Methyl-1,3-propanediol siv ua tus nqa khoom lossis cov kuab tshuaj hauv kev tsim cov tshuaj xa khoom, cov kua tshuaj, thiab cov tshuaj pleev. Nws qhov sib xws nrog ntau yam tshuaj ua rau nws yog ib qho khoom xyaw tseem ceeb hauv kev tsim cov khoom siv tshuaj zoo thiab ruaj khov. Ntxiv mus, cov tshuaj no siv ua tus neeg sawv cev tiv thaiv kev khov hauv kev siv hauv kev lag luam vim nws muaj peev xwm txo qhov khov ntawm cov dej-raws li cov kua. Nws siv rau hauv cov qauv txias rau tsheb thiab cov khoom siv hauv kev lag luam pab tiv thaiv kev khov thiab xeb, ua kom ntseeg tau tias kev ua haujlwm ntawm cov tshuab thiab tsheb hauv qhov chaw txias. Zuag qhia tag nrho, 2-Methyl-1,3-propanediol ua lub luag haujlwm tseem ceeb hauv kev tsim cov ntaub ntawv siab heev, cov khoom siv saib xyuas tus kheej, cov tshuaj npaj, thiab cov kua dej hauv kev lag luam, pab txhawb kev txhim kho ntawm ntau yam khoom siv rau cov neeg siv khoom, cov txheej txheem kev lag luam, thiab cov ntawv thov kev kho mob.
