Kune akawanda makirasi emakomisheni anobatsira seanodzoreredza moto.Nepo parizvino chikamu chidiki chemusika uyu mukuru, Magnesium Hydroxide iri kukwezva kutarisa nekuda kwekuita kwayo, mutengo, kuderera kwekuora, uye kuderera kwehuturu.Ikozvino musika wemagnesium hydroxide mune zvinodzoreredza murazvo ungangoita mamirioni gumi emapaunzi pagore, uine mukana wekupfuura mamirioni makumi matatu epaunzi pagore munguva pfupi iri kutevera.
Mg(OH)2 inoshandiswa seFR mune zvekutengesa fenicha zvikumbiro muUnited States uye mune yekutengesa uye yekugara fenicha muUnited Kingdom (Fire Retardant Chemicals Association 1998).Kugadzikana kweMg(OH)2 pakudziya kwepamusoro pe300°C kunobvumira kuti iiswe mumapolymer akati wandei (IPCS 1997).Soko-vhoriyamu data rakabudiswa muna 1993 rinokurudzira kuwedzera kushandiswa kweMg(OH)2 seFR.Zvingangoita zviuru zviviri uye zviuru zvitatu zveMg(OH)2 zvakatengeswa seFR muUnited States muna 1986 na1993, zvichiteerana (IPCS 1997).
Magnesium hydroxide (Mg(OH)2), is acid- uye halogen-isina murazvo unodzoreredza kumapurasitiki akasiyana.Magnesium hydroxide ine 100oC yakakwira decomposition tembiricha kupfuura ATH, ichibvumira tembiricha yepamusoro yekugadzirisa mukusanganisa uye kuburitsa purasitiki.Zvakare, magnesium hydroxide adsorbs yakawanda simba panguva yekuora maitiro.
Magnesium hydroxide inoshanda senge inodzoreredza murazvo uye inodzvanya chiutsi mumapurasitiki kunyanya nekubvisa kupisa kubva mupurasitiki panguva yekuparara kwayo kuita magnesium oxide nemvura.Mupfunga wemvura unogadzirwa unoderedza mafuta anowanikwa mumurazvo.Zvigadzirwa zvekuora zvinodzivirira purasitiki kubva pakupisa uye zvinogadzira char iyo inotadzisa kuyerera kwemagasi anogona kunge achibvira kumoto.
Kuti murazvo wemoto ubatsire mumapurasitiki akasanganiswa, haafanire kushatisa chimiro chepurasitiki.Mune yakajairwa inochinjika waya PVC magadzirirwo, ZEHUI CHEM 'yakawanikwa ichivandudza zvishoma zvimiro zvePVC kuumbwa zvichienzaniswa neATH uye inokwikwidza, yepamusoro giredhi magnesium hydroxide.
