Magnesium Oxide da ake amfani da shi don Masana'antar Rubber

Magnesium Oxides (MgOs)An yi amfani da shi a cikin Masana'antar Rubber fiye da shekaru 100.Ba da daɗewa ba bayan gano vulcanization na sulfur a cikin 1839, MgO da sauran inorganic oxides sun tabbatar da haɓaka jinkirin maganin sulfur da aka yi amfani da shi kadai.Sai a farkon shekarun 1900 lokacin da aka ɓullo da injiniyoyi masu haɓakawa da maye gurbin magnesium da sauran oxides a matsayin masu haɓakawa na farko a cikin tsarin warkarwa.Amfanin MgO ya ragu har zuwa farkon 1930s lokacin haifuwar sabon elastomer na roba wanda yayi amfani da wannan oxide da yawa don daidaitawa da kawar da (acid scavenge) fili-polychloroprene (CR).Har yanzu, a farkon ƙarni na gaba, farkon amfani da MgO a cikin masana'antar roba har yanzu yana cikin tsarin warkarwa na polychloroprene (CR).A cikin shekarun da suka wuce, masu haɗin gwiwa sun fahimci fa'idodin MgO a cikin sauran elastomers kamar: chlorosulfonated polyethylene (CSM), fluoroelastomer (FKM), halobutyl (CIIR, BIIR), hydrogenated NBR (HNBR), polyepichlorohydrin (ECO) da sauransu.Bari mu fara duba yaddarubber grade MgOsana samar da su da dukiyoyinsu.
