Cov kuab tshuaj ua lub luag haujlwm tseem ceeb hauv cov nplaum. Qee tus ua tus neeg kho kom haum xeeb hauv cov tshuaj tiv thaiv polymerization, ua rau cov tshuaj tiv thaiv qeeb thiab ua kom yooj yim tswj qhov kub thiab txias; lwm tus purify monomers thiab additives; qee qhov yaj cov khoom siv los ua ib feem ntawm cov nplaum; ib co dilute cov nplaum rau ib qho viscosity, txhawb kev ntub dej thiab yooj yim daim ntawv thov; ib co tswj tus nqi evaporation; qee qhov tiv thaiv gelation thiab ua kom ruaj khov; ib co ua hauj lwm raws li tus neeg saib xyuas nto ua ntej sib txuas; qee qhov yog siv rau kev sib txuas ncaj qha ntawm qee yam khoom siv thermoplastic; thiab qee qhov tuaj yeem txo cov nqi thiab txhim kho kev ua haujlwm zoo.
Kev xaiv cov kuab tshuaj zoo yog qhov tseem ceeb, yuav tsum tau xav txog ntau yam xws li solubility, evaporation tus nqi, kev nyab xeeb, kev lag luam, muaj, thiab ruaj khov. Cov kuab tshuaj zoo yuav tsum muaj cov khoom solubility zoo heev, uas tuaj yeem txiav txim siab los ntawm kev solubility thiab hydrogen bonding Performance index. Tus nqi ziab ntawm cov nplaum yog ncaj qha ntsig txog qhov hnyav tus nqi evaporation. Cov kuab tshuaj-raws li cov nplaum yuav tsum muaj cov kuab tshuaj evaporate. Feem ntau, kev ziab sai yog xav tau, uas yuav tsum xaiv cov kuab tshuaj nrog cov ntsiab lus qis dua. Feem ntau cov organic solvents yog flammable, thiab thaum hnyav vapors ncav cuag ib qho concentration nyob rau hauv cov huab cua, lawv tuaj yeem tawg. Yog li ntawd, kev nyab xeeb hnyav yuav tsum tau ua tib zoo xav txog. Cov kuab tshuaj organic feem ntau kuj yog tshuaj lom, ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv thiab ua rau ib puag ncig, thiab yuav tsum tau txais kev saib xyuas txaus. Cov kuab tshuaj ua ib feem loj ntawm cov kuab tshuaj-raws li cov nplaum, yog li tus nqi yuav tsum tau txiav txim siab; pheej yig thiab yooj yim muaj kuab tshuaj yuav tsum tau siv thaum twg los tau.
