Cov Khoom Siv Roj Teeb Hnab
Styrene butadiene roj hmab (SBR)
Kev piav qhia txog khoom
Styrene butadiene roj hmab: ib qho roj hmab hluavtaws ua los ntawm kev sib xyaw ua ke ntawm styrene thiab butadiene. Nws cov mis tshuaj lom neeg tuaj yeem qhia ua: - (CH2-CH = CH-CH2) m - (CH-CH2) n -; Ua ib qho nplaum rau cov electrodes, nws txhim kho lub zog kho tshuab thiab kev ruaj khov ntawm cov electrodes.
