Magnesium Oxides (MgOs)yakashandiswa muRubber Indasitiri kweanopfuura makore zana.Nguva pfupi mushure mekuwanikwa kwe sulfur vulcanization muna 1839, MgO nemamwe maokisidi emhando yakaratidza kukurumidza kunonoka kurapwa kwesarufa inoshandiswa yoga.Yakanga isiri kusvika kumavambo 1900s apo organic accelerators yakagadzirwa uye yakatsiviwa magnesium nemamwe maokisise seyekutanga accelerator mukurapa masisitimu.Kunwiwa kweMgO kwakadzikira kusvika kutanga kwema1930 panguva yekuzvarwa kweimwe itsva yakagadzirwa elastomer iyo yakashandisa okisidhi iyi zvakanyanya kudzikamisa nekumisa (acid scavenge) iyo compound-polychloroprene (CR).Kunyangwe ikozvino, pakutanga kwezana rinotevera, iyo yekutanga kushandiswa kweMgO muindasitiri yerabha ichiri mu polychloroprene (CR) kurapa masisitimu.Nekufamba kwemakore, macompounders akaziva mabhenefiti eMgO mune mamwe elastomer akadai se: chlorosulfonated polyethylene (CSM), fluoroelastomer (FKM), halobutyl (CIIR, BIIR), hydrogenated NBR (HNBR), polyepichlorohydrin (ECO) pakati pevamwe.Ngatitangei kutarisa kuti seirubber giredhi MgOszvinogadzirwa uye maitiro avo.
Pakutanga muindasitiri yerabha imwe chete yemhando yeMgO yaivepo-inorema (nekuda kwekuwanda kwayo).Rudzi urwu rwakagadzirwa nekuora kwekushisamaginesi chaiwo(MgCO2).Giredhi raizobuda raiwanzove risina kuchena, risinganyanyi kushanda uye raive nehukuru hukuru.Nekuvandudzwa kweCR, vagadziri veMagnesia vakagadzira hutsva, hutsanana hwepamusoro, hunoshanda, hudiki hudiki saizi MgO-yakawedzera mwenje.Ichi chigadzirwa chakagadzirwa ne thermally decomposing basic magnesium carbonate (MgCO3).Ichiri kushandiswa nhasi mumishonga uye zvizorwa, iyi MgO yakatsiviwa neyakagwinya, diki diki saizi MgO-mwenje kana hunyanzvi mwenje.Vanenge vese vanogadzira rubber vanoshandisa rudzi urwu rweMgO.Inogadzirwa ne thermally decomposing magnesium properties 2 marudzi: akaendererahydroxide (Mg(OH)2).Hukuru hwayo huri pakati pehuya hwekuremera uye hwekuwedzera chiedza uye ine chiitiko chepamusoro-soro uye saizi diki.Izvi zviviri zvekupedzisira zvivakwa-chiitiko uye particle size-ndidzo dzakanyanya kukosha zvimiro zvechero MgO inoshandiswa murubha musanganiswa.
