Momwe mungasiyanitsire kuwala kwa magnesium oxide ndi heavy magnesium oxide

Ndi kupita patsogolo kwa mafakitale, magnesium okusayidi wakhala chimagwiritsidwa ntchito mankhwala zopangira, koma mafakitale osiyanasiyana ndi zofunika zosiyanasiyana magawo ndi zizindikiro za magnesium okusayidi, kotero pali mitundu yambiri ya magnesium okusayidi pa msika, monga kuwala ndi heavy magnesium. oxide.Kodi pali kusiyana kotani pakati pawo?Lero Zehui akuwonetsani iwo kuchokera kuzinthu zinayi.

1. Zosiyanasiyana zochulukirapo

Kusiyana kwachidziwitso pakati pa kuwala ndi heavy magnesium oxide ndiko kuchuluka kwake.Magnesium okusayidi yowala imakhala ndi kachulukidwe kakang'ono kwambiri ndipo ndi ufa woyera wa amorphous, womwe umagwiritsidwa ntchito m'mafakitale apakatikati komanso apamwamba.Heavy magnesium oxide imakhala ndi kachulukidwe kakang'ono ndipo ndi yoyera kapena beige ufa, yomwe nthawi zambiri imagwiritsidwa ntchito m'mafakitale otsika.Kuchulukirachulukira kwa magnesium oxide wopepuka kumakhala pafupifupi kuwirikiza katatu kuposa heavy magnesium oxide.

2. Makhalidwe osiyanasiyana

Kuwala kwa magnesium oxide kuli ndi mphamvu ya fluffiness ndi insolubility.Sisungunuka m'madzi oyera ndi zosungunulira organic, koma sungunuka mu acid ndi ammonium salt solution.Pambuyo pa calcination yotentha kwambiri, imatha kusinthidwa kukhala makhiristo.Heavy magnesium oxide imakhala ndi kachulukidwe komanso kusungunuka.Imagwira mosavuta ndi madzi kuti ipange zosakaniza, ndipo imatenga mosavuta chinyezi ndi mpweya woipa ikafika pamlengalenga.Mukasakaniza ndi magnesium chloride solution, imapanga gelatinous harderer mosavuta.

3. Njira zosiyanasiyana zokonzekera

Magnesium oxide yopepuka nthawi zambiri imapezeka ndi zinthu zomwe zimasungunuka m'madzi, monga magnesium chloride, magnesium sulfate kapena magnesium bicarbonate, kukhala zinthu zomwe sizisungunuka m'madzi ndi njira zama mankhwala.Magnesium oxide yowala yomwe imapangidwa imakhala ndi kachulukidwe kakang'ono, nthawi zambiri 0.2(g/ml).Chifukwa cha njira zovuta zopangira, izi zimabweretsanso ndalama zopangira zopangira komanso mitengo yamtengo wapatali yamsika.Heavy magnesium oxide nthawi zambiri imapezeka ndi calcining magnesite kapena brucite ore.Magnesium oxide olemera omwe amapangidwa amakhala ndi kachulukidwe kokulirapo, nthawi zambiri 0.5(g/ml).Chifukwa cha njira yosavuta yopangira, mtengo wogulitsa umakhalanso wotsika.

4. Magawo osiyanasiyana ogwiritsira ntchito

Kuwala kwa magnesium okusayidi kumagwiritsidwa ntchito kwambiri popanga zinthu za mphira ndi zomatira za mphira za chloroprene, zomwe zimagwira ntchito ya acid absorber ndi accelerator popanga mphira.Imagwira ntchito yochepetsera kutentha kwa sintering mu ceramics ndi enamel.Amagwiritsidwa ntchito ngati zodzaza popanga mawilo opera, utoto ndi zinthu zina.Magnesium oxide wopepuka wa chakudya amatha kugwiritsidwa ntchito ngati decolorizer popanga saccharin, ayisikilimu ufa wowongolera PH ndi zina zotero.Itha kugwiritsidwanso ntchito m'munda wamankhwala, monga antiacid ndi laxative ndi zina zotero.Heavy magnesium oxide imakhala ndi chiyero chochepa kwambiri ndipo imatha kugwiritsidwa ntchito kupanga mchere wambiri wa magnesium ndi mankhwala ena.Itha kugwiritsidwanso ntchito pantchito yomanga ngati chodzaza chopangira zinthu zapansi zopangira mankhwala, miyala ya miyala ya marble, denga, matabwa otsekereza kutentha ndi zina zotero.
