Polybutadiene mai narkewa (EPB)
EPB ƙungiyar epoxy ce da aka shigar a cikin sarkar kwayoyin halitta ta PB, wadda ke da fa'idodin juriyar mai, juriyar tsufa, bayyanannen abu mai kyau, aiki mai ƙarancin zafin jiki, da sauransu. Ƙungiyar epoxy a cikin sarkar kwayoyin halitta ƙungiya ce mai amsawa, wadda za a iya warkar da ita da nau'ikan isocyanates da magungunan warkar da epoxy.
Polymer ɗin da aka warke yana da kyawawan halaye na jiki da sinadarai, ƙarfin haɗin kai mai kyau ga ƙarfe da gilashi da sauran kayan da ba na ƙarfe ba, kyawawan halaye na dielectric, ƙarancin raguwar raguwa, babban tauri, tsayayye zuwa alkali da mafi yawan ƙarar, wanda zai iya inganta halayen injiniya sosai, ƙarfin haɗin kai da juriyar zafi na kayan polyurethane.
Rukunin polar suna inganta halayen haɗin samfurin tare da kayan ƙarfe da waɗanda ba ƙarfe ba; Ana iya amfani da shi a cikin manne, sealants, shafi, ƙarfafa resin epoxy, polyurethane elastomers, da sauransu.
An saka a cikin 50kg/ganga, 170kg/ganga, Lokacin ajiya shine shekara 1.
Umarnin tsaro:
Ya kamata a ajiye a wuri mai sanyi, bushe kuma a bar iska ta shiga. Mafi kyawun yanayi shine tsakanin -20 ~ 38℃. Tsawon lokacin ajiyar shine watanni 12, idan ya ƙare, har yanzu ana amfani da shi idan ya dace da ƙa'ida ta hanyar sake gwadawa. Idan sufuri ya kamata a guji ruwan sama, a guji hasken rana. Kar a haɗa shi da mai ƙarfi na oxidizing.
