Hoʻohana ʻia ka Magnesium Oxide no ka ʻoihana Rubber

ʻO nā ʻokikene Magnesium (MgOs)ua hoʻohana ʻia ma ka ʻoihana Rubber no nā makahiki he 100.Ma hope koke iho o ka ʻike ʻia ʻana o ka vulcanization sulfur i ka makahiki 1839, ua hōʻoia ʻo MgO a me nā ʻokikene ʻokoʻa ʻē aʻe i ka wikiwiki o ka hoʻōla lohi o ka sulfur i hoʻohana wale ʻia.ʻAʻole ia a hiki i ka makahiki 1900 i hoʻomohala ʻia ai nā mea hoʻokele organik a hoʻololi i ka magnesium a me nā oxide ʻē aʻe ma ke ʻano he mea hoʻokele mua i nā ʻōnaehana hoʻōla.Ua emi iho ka hoʻohana ʻana o MgO a hiki i ka makahiki 1930 i ka wā o ka hānau ʻana o kahi elastomer synthetic hou i hoʻohana nui i kēia oxide no ka hoʻopaʻa ʻana a hoʻopaʻa ʻole (acid scavenge) i ka pūhui-polychloroprene (CR).ʻOiai i kēia manawa, i ka hoʻomaka ʻana o ke kenekulia e hiki mai ana, ʻo ka hoʻohana mua ʻana o MgO i loko o ka ʻoihana pāpaʻi i loko o nā ʻōnaehana hoʻōla polychloroprene (CR).I loko o nā makahiki, ua ʻike nā mea hoʻohui i nā pono o MgO i nā elastomers ʻē aʻe e like me: chlorosulfonated polyethylene (CSM), fluoroelastomer (FKM), halobutyl (CIIR, BIIR), hydrogenated NBR (HNBR), polyepichlorohydrin (ECO) a me nā mea ʻē aʻe.E nana mua kakou peheaʻO nā MgO papa lāʻauhana ʻia a me kā lākou mau waiwai.

I ka hoʻomaka ʻana o ka ʻoihana pāpaʻi hoʻokahi wale nō ʻano MgO i loaʻa-kaumaha (ma muli o kona ʻano nui).Ua hana ʻia kēia ʻano e ka thermally decomposingnā magnesite kūlohelohe(MgCO2).ʻAʻole maʻemaʻe ka pae i loaʻa, ʻaʻole ʻeleʻele a nui ka nui o ka ʻāpana.Me ka hoʻomohala ʻana o CR, ua hoʻopuka nā mea hana magnesia i kahi mea hou, maʻemaʻe kiʻekiʻe, ʻoi aku ka ikaika, ʻoi aku ka liʻiliʻi liʻiliʻi MgO-māmā.Ua hana ʻia kēia huahana e ka hoʻoheheʻe ʻana o ka magnesium carbonate kumu (MgCO3).Hoʻohana mau ʻia i kēia mau lā i nā lāʻau lapaʻau a me nā mea hoʻonaninani, ua hoʻololi ʻia kēia MgO e kahi māmā ikaika loa, liʻiliʻi liʻiliʻi MgO-māmā a i ʻole ke kukui ʻenehana.Ma kahi kokoke i nā mea hoʻohui i ka lāʻau lapaʻau e hoʻohana i kēia ʻano MgO.Hana ʻia e ka thermally decomposing magnesium properties 2 ʻano: hoʻomauwaihā (Mg(OH)2).Aia kona mānoanoa nui ma waena o ka māmā kaumaha a me ka māmā keu a he hana kiʻekiʻe loa kona a me ka nui o nā ʻāpana liʻiliʻi.ʻO kēia mau waiwai hope ʻelua - ka hana a me ka nui o nā ʻāpana - nā waiwai koʻikoʻi o kēlā me kēia MgO i hoʻohana ʻia i ka hui pū ʻana.
