Taw qhiathiab daim ntawv thov CAS 9010-85-9|Butyl Roj Hmab
Butyl roj hmab (IIR luv luv) yog plaub hom hluavtaws roj hmab (SR) loj tshaj plaws hauv ntiaj teb. Nws yog cov khoom ntawm cationic polymerization ntawm isobutylene thiab isoprene nyob rau hauv qhov kev txiav txim ntawm Friedel-Craft catalyst. Nws tshwm li dawb los yog lub teeb daj muaju. Nws tsis muaj ntxhiab thiab tsis qab, muaj qhov hloov pauv iav qis heev thiab yog insoluble hauv ethanol thiab acetone. Butyl roj hmab tuaj yeem tsim los ntawm polymerizing isobutylene thiab isoprene nrog lub catalyst (txhuas trichloride) thiab kub tsis tshua muaj (-98 degree ).
Butyl Roj Hmab yog siv rau hauv kev tsim cov log tsheb sab hauv, diaphragms ntawm shaper-vulkanizers, latex ntawm butyl roj hmab thiab ntau lwm yam kev siv. Saib cov ntawv qhia tshwj xeeb ntawm cov khoom hauv qab no rau kev siv ntxiv.

| Cov yam ntxwv tseem ceeb | ||||
| Tsawg roj permeability. BIIR & CIIR muab kev kho kom zoo dua qub. | ||||
| Lus Teb Ntxiv | ||||
| Cov roj hmab no muaj siab heev impermeability rau gases thiab yog li no siv rau lub puab hlab thiab ob sab ntawm pneumatic log tsheb thiab nyob rau hauv lub tshuab nqus tsev thiab siab siab daim ntaub ntawv. Nws muaj qhov txawv txav tsis zoo ntawm qhov poob siab yog li ntawd, txawm hais tias muaj qhov hloov pauv iav qhov kub qis li -65 degree, nws qhia tau tias muaj kev kub ntxhov ntawm qhov kub thiab txias. Nws muaj ozone zoo, huab cua, cua sov thiab tshuaj tiv thaiv. Tsis haum rau kev sib cuag nrog cov ntxhia roj. | ||||
