Nrog rau kev nce qib ntawm kev lag luam, magnesium oxide tau dhau los ua cov khoom siv dav siv tshuaj, tab sis cov kev lag luam sib txawv muaj cov kev xav tau sib txawv rau cov ntsuas thiab ntsuas ntawm magnesium oxide, yog li muaj ntau hom magnesium oxide nyob rau hauv kev ua lag luam, xws li lub teeb thiab hnyav magnesium. oxide.Qhov txawv ntawm lawv yog dab tsi?Hnub no Zehui yuav qhia lawv rau koj los ntawm plaub yam.
1. Ntau qhov sib txawv
Qhov sib txawv tshaj plaws ntawm lub teeb thiab hnyav magnesium oxide yog qhov ntom ntom.Lub teeb magnesium muaj qhov ntom ntom ntom ntom ntom thiab yog hmoov dawb amorphous, uas feem ntau yog siv hauv nruab nrab thiab siab tshaj kev lag luam.Hnyav magnesium oxide muaj ib qho me me me me thiab yog cov hmoov dawb los yog beige, uas feem ntau yog siv hauv kev lag luam qis kawg.Qhov ntom ntom ntawm lub teeb magnesium oxide yog li peb npaug ntawm qhov hnyav magnesium oxide.
2. Cov khoom sib txawv
Lub teeb magnesium oxide muaj cov khoom ntawm fluffiness thiab insolubility.Nws yog insoluble hauv dej ntshiab thiab cov kuab tshuaj organic, tab sis soluble hauv acid thiab ammonium ntsev daws.Tom qab kub-kub calcination, nws tuaj yeem hloov mus rau hauv cov muaju.Hnyav magnesium oxide muaj cov yam ntxwv ntawm qhov ntom ntom thiab solubility.Nws yooj yim reacts nrog dej los tsim cov tebchaw, thiab yooj yim absorbs ya raws thiab carbon dioxide thaum raug huab cua.Thaum tov nrog magnesium chloride tov, nws yooj yim tsim ib gelatinous hardener.
3. Cov txheej txheem npaj sib txawv
Lub teeb magnesium oxide feem ntau tau txais los ntawm calcining tshuaj uas yog soluble hauv dej, xws li magnesium chloride, magnesium sulfate los yog magnesium bicarbonate, rau hauv cov khoom uas insoluble hauv dej los ntawm kev siv tshuaj.Lub teeb magnesium oxide tsim muaj qhov ntom ntom me me, feem ntau 0.2 (g / ml).Vim yog cov txheej txheem ntau lawm, qhov no kuj ua rau cov nqi tsim khoom ntau dua thiab cov nqi lag luam kuj tseem siab dua.Hnyav magnesium oxide feem ntau tau txais ncaj qha calcining magnesite lossis brucite ore.Qhov hnyav magnesium oxide tsim muaj qhov loj dua, feem ntau 0.5 (g / ml).Vim cov txheej txheem tsim khoom yooj yim, tus nqi muag khoom kuj tseem qis.
4. Cov ntawv thov sib txawv
Lub teeb magnesium oxide feem ntau yog siv rau kev tsim cov khoom siv roj hmab thiab chloroprene roj hmab adhesives, ua si lub luag haujlwm ntawm acid absorber thiab accelerator hauv kev tsim roj hmab.Nws plays lub luag hauj lwm ntawm kev txo cov sintering kub nyob rau hauv ceramics thiab enamel.Nws yog siv los ua tus muab tub lim hauv kev tsim cov khoom sib tsoo, xim thiab lwm yam khoom.Khoom noj khoom haus-qib lub teeb magnesium oxide tuaj yeem siv los ua tus decolorizer rau saccharin ntau lawm, ice cream hmoov PH regulator thiab lwm yam.Nws tseem tuaj yeem siv rau hauv kev lag luam tshuaj, ua tshuaj antacid thiab laxative thiab lwm yam.Hnyav magnesium oxide muaj qhov purity tsawg thiab tuaj yeem siv los tsim ntau yam magnesium ntsev thiab lwm yam khoom siv tshuaj.Nws tseem tuaj yeem siv rau hauv kev tsim kho kev lag luam raws li kev muab tub lim rau kev ua cov khoom siv tshuaj lom neeg hauv pem teb, cov plag tsev marble, ceilings, rwb thaiv tsev kub thiab lwm yam.
