Cov txheej txheem tsim khoom ntawm roj hmab automotive qhov chaw ua ke nrog polymer chemistry, cov ntaub ntawv tshawb fawb, thiab precision machining technology. Ua ntej, cov khoom siv roj hmab nrog cov khoom tshwj xeeb yog tsim los ntawm cov tshuaj tiv thaiv polymerization. Cov txheej txheem no suav nrog kev tswj xyuas meej ntawm qhov tsis xws li qhov kub thiab txias, siab, thiab cov catalysts kom ntseeg tau tias cov roj hmab cov qauv molecular ua tau raws li cov qauv tsim. Tom qab ntawd, los ntawm cov txheej txheem xws li kev sib tov, calendering, molding, thiab vulcanization, cov roj hmab tau ua tiav rau hauv qhov chaw ntawm cov duab thiab qhov loj me. Cov txheej txheem vulcanization yog qhov tseem ceeb tshwj xeeb; nws siv cov cua sov thiab lub siab los ua tus ntoo khaub lig- cov qauv sib txuas ntawm cov roj hmab molecules, yog li endowing qhov chaw nrog lub cev ruaj khov thiab ruaj khov.
Roj hmab automotive qhov chaw xa mus rau cov khoom siv feem ntau ntawm cov roj hmab siv rau kev sib dhos, kho, lossis hloov tsheb. Cov khoom no tuav lub luag haujlwm tseem ceeb hauv kev lag luam tsheb vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb, xws li elasticity, hnav tsis kam, thiab corrosion kuj. Lawv tau siv dav hauv ntau lub tshuab tsheb, suav nrog tab sis tsis txwv rau lub tshuab ncua kev kawm, lub tshuab nres tsheb, lub tshuab cav, roj tshuab, thiab lub cev ntsaws ruaj ruaj.
