Mg(OH)2 Codsiyada
Magnesium hydroxide waa olol aad u fiican oo dib u celisa caagagga iyo alaabta caagga ah.Sida ilaalinta deegaanka, sida wakiilka desulfurization gaaska flue, waxay bedeli kartaa alkali iyo lime sida wakiilka dhexdhexaad ah iyo wakiilka adsorption biraha culus ee biyaha wasakhda acid.Intaa waxaa dheer, waxaa sidoo kale loo isticmaali karaa warshadaha elektiroonigga ah, sifaynta daawada iyo sonkorta, qalabka dahaadhka iyo soo saarista alaabta kale ee cusbada magnesium.Magnesium hydroxide waxa loo isticmaalaa sidii qiiqa dareeraha nuugista.Inta badan nadiifinta qiiqa qiiqa iyo habka gypsum-ka lime ayaa la isticmaalay ka hor 1970-yadii.Sababo la xiriira wasakhowga sare ee alaabada deegaanka, hydrogen-ka ayaa la isticmaalay ilaa 1980-meeyadii.Habka Magnesium oxide;biyaha wasakhda ah ee acidic;resin flame retardant oo la isku daray, kaas oo isticmaali jiray bromine, fosfooraska, koloriin, iyo cusbada aan organic ahayn waagii hore.Badeecooyinkan intooda badan waxaa loo isticmaalay alaabtan.Magnesium, inta badan sababtoo ah magnesium hydroxide hydroxide ee xabagta caagga ah ee kulaylka ah waxay kordhin kartaa fuuqbaxa iyo heerkulka kala-baxa ee ka sarreeya 350 ° C.
Adeegga iyo Tayada
Halabuurka kiimikada ee alaabtayada, qaybinta xajmiga qaybahooda, helitaanka noocyada kala duwan ee dahaarka, iyo xitaa xajinta qaabka crystal ee alaabtayada: dhammaan xuduudahan ayaa fure u ah waxqabadka qumman ee qaababkaaga.Budada Magnesium hydroxide waxaa loogu talagalay inay u dhaqanto sidii olol wax ku ool ah dib u dhigista iyo xakamaynta qiiqa wax lagu daro, gaaritaanka dib u dhac ololka sare, qiiqa qiiqa yareeya iyo nuugista gaasta sunta ah iyada oo aan si xun u saameynayn sifooyinka farsamada.Nidaamkeeda xasilloon ayaa u oggolaanaysa in lagu daro polymers marka la raro rarida la rabo iyada oo aan si xun u saameynayn sifooyinka waxqabadka.Marka la taabto dabka, waxay u jajaban tahay iyadoo loo eegayo falcelinta endothermic, oo sii daaya gaasaska dareeraha ah ee heerkulka u dhow kala-goynta polymerka.Taasi waa sababta aanu u bixinayno kala duwanaansho wax soo saar oo dhamaystiran codsigan.Waan ku farxi doonaa inaan kugu hagno mashruuc guul leh.
