Mea Pākahi ʻEke
ʻO ka laholio Styrene butadiene (SBR)
Wehewehe Huahana
ʻO ka laholio Styrene butadiene: kahi laholio synthetic i hana ʻia e ka copolymerization o styrene a me butadiene. Hiki ke hōʻike ʻia kona ʻano kemika penei: - (CH2-CH=CH-CH2) m - (CH-CH2) n -; Ma ke ʻano he mea hoʻopili no nā electrodes, hoʻomaikaʻi ia i ka ikaika mechanical a me ke kūpaʻa o nā electrodes.
