Styrene butadiene roj hmab, uas tau hais tias tsuas yog cov roj hmab hluavtaws hauv ntiaj teb, yog nyiam nyob rau ntau qhov chaw niaj hnub no.Nws muaj butadiene thiab styrene, thiab 75 txog 25 copolymer.Nws feem ntau yog siv rau hauv kev tsim cov tsheb log tsheb, hloov cov roj hmab hnav-resistant.
Butadiene roj hmab muaj ib feem loj ntawm tag nrho cov hluavtaws roj hmab tsim nyob rau hauv lub ntiaj teb no.Raws li cov ntsiab lus styrene nce, nws ua nyuaj thiab qhia tau hais tias muaj zog ntawm qhov kub thiab txias.
Lub ntsiab kom zoo dua ntawm kev siv styrene butadiene roj hmab yog tias nws yog kev lag luam thiab ruaj khov.Nrog nws cov yam ntxwv zaum, nws tiv taus cov hauv paus, glycol-based nres roj thiab cawv.
Cov chaw tseem ceeb ntawm kev siv styrene rubbers, uas tseem tiv thaiv crystallization, yog raws li hauv qab no:
● Cov ntsaws ruaj ruaj,
● Kev lag luam hluav taws xob,
● Cov khoom siv ncaws pob,
● Lub tshuab ntxhua khaub ncaws,
● Tsheb log tsheb,
● Nws kuj yog siv los tsim cov khoom tub yees.
Cov khoom ntawm Styrenes:
Lawv muaj ib tug reactive qauv uas yog soluble nyob rau hauv dej rau ib tug tsawg npaum li cas.Txawm hais tias tsis tshua muaj tshwm sim, lawv muaj cov yam ntxwv tsw qab thiab tsis muaj zog heev.Cov khoom no, uas yog siv rau hauv kev tsim cov polymers, yog ua tiav los ntawm kev siv ntau yam thev naus laus zis.Nws yog ib qho ntawm cov khoom siv yas nyiam tshaj plaws hauv ntiaj teb.
