90/40
Bitumen muaj 90/40 yog cov qib mos ntawm oxidized bitumen nrog lub softening point thiab nkag mus rau thaj tsam 90C + 5 thiab nkag mus rau 40 +5 desimillimiter. Bitumen 90/40 yog ib nrab khoom nrog qee qhov yooj yim piv rau cov qib nyuaj thiab feem ntau yog siv hauv khw African.
Yuav ua li cas bitumen 90/40 tsim?
Bitumen yog ib hom hydrocarbon thiab tom qab lub hom phiaj thiab tshem tawm cov hydrogen, cov pa roj carbon ntau yuav tshem tawm thiab ua nyuaj. Los ntawm txhaj cov cua kub rau cov bitumen cov pa oxygen ntawm cov pa yuav ua ke nrog hydrogen ntawm bitumen thiab ua rau H2O thiab vapor thiab cov bitumen tseem tshuav yog cov ntsiab lus carbon ntau dua thiab hu ua oxidized bitumen.
