Cov roj hmab Butadiene Styrene ua kua (LSBR)
LSBR yog ib qho copolymer uas tsis muaj molecular hnyav ntawm butadiene thiab styrene nrog qhov hnyav molecular ntawm 2000-10000. Nws muaj kev rwb thaiv hluav taws xob zoo heev thiab cov khoom siv lub cev, thiab feem ntau siv rau hauv ntau qhov chaw xws li cov laug cam, cov nplaum thiab cov ntaub ntawv sealing.
Piv nrog cov kua polybutadiene (LPB), LSBR muaj qhov kub hloov iav siab dua thiab zoo dua kub thiab hnav tsis kam. Hloov LPB nrog LSBR tuaj yeem txhim kho qhov tshwm sim ntawm cov nplaum thaum lub sijhawm ua cov phaj tooj liab.
Ntim rau hauv 50kg / nruas, 170kg / nruas, Lub sijhawm cia khoom yog 1 xyoos.
Cov lus qhia txog kev nyab xeeb:
Kev khaws cia yuav tsum tau khaws cia rau qhov chaw txias, qhuav thiab muaj cua nkag. Qhov kub zoo tshaj plaws yog -20 ~ 38 ℃. Lub sijhawm khaws cia yog 12 lub hlis, yog tias tas sij hawm, tseem siv tau yog tias ua tau raws li tus qauv los ntawm kev rov kuaj dua. Thaum thauj mus los yuav tsum tsis txhob los nag lossis tshav ntuj. Tsis txhob sib tov nrog cov tshuaj oxidizing muaj zog.
