Kugwiritsa Ntchito Ndi Kufunika Kwa Magnesium Hydrooxide

Magnesium hydroxide (Mg (OH) ₂) ndi ufa woyera, wa amorphous wokhala ndi mankhwala okhazikika komanso kukana kutentha kwambiri, kutentha kwa moto, komanso kusokoneza katundu, kuchita mbali yofunika kwambiri m'madera osiyanasiyana.

M'munda woletsa malawi, magnesium hydroxide ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi inorganic flame retardants. Ikavunda ndi kutentha, imatulutsa madzi ochulukirapo a crystalline, omwe amatenga kutentha ndi kusungunula mpweya woyaka, ndikuletsa kuyaka bwino. Poyerekeza ndi mankhwala oletsa malawi a halogenated, magnesium hydroxide ndi yopanda poizoni-ndi yopanda utsi, ikukwaniritsa zofunikira zachilengedwe. Amagwiritsidwa ntchito kwambiri mu mapulasitiki, mphira, zingwe, ndi zida zophatikizika.

M'munda wamankhwala, magnesium hydroxide nthawi zambiri imagwiritsidwa ntchito ngati antacid ndi mankhwala ofewetsa tuvi tolimba. Mphamvu zake za alkaline zimatha kuchepetsa asidi m'mimba, kuchepetsa kutentha kwa mtima ndi kusadya bwino, komanso{1}}mankhwala a purrity magnesium hydroxide amagwiritsidwanso ntchito pochiza kudzimbidwa. Akuphunziridwanso ngati mankhwala ophera poizoni wa heavy metal chifukwa amatha kumangirira ku ayoni achitsulo enaake oopsa, kumachepetsa kuyamwa kwawo ndi thupi.

M'munda woteteza zachilengedwe, magnesium hydroxide imagwiritsidwa ntchito ngati mankhwala opangira madzi otayira, kuchotsa bwino zinthu za acidic, ayoni azitsulo zolemera (monga lead ndi cadmium), ndi fluoride m'madzi onyansa. Zomwe zimapangidwira, zomwe zimakhala ndi mpweya wosasungunuka bwino wa hydroxide, zimasefedwa mosavuta ndikuzilekanitsa, ndikupangitsa kuti ikhale yofunika kwambiri pakuyeretsa madzi onyansa a mafakitale.

Popanga mafakitale, magnesium hydroxide imagwiritsidwanso ntchito pokonzekera mankhwala ena a magnesium, monga magnesium oxide (kudzera calcination) ndi mchere wa magnesium. Kuphatikiza apo, imagwiritsidwa ntchito ngati chodzaza kapena chowonjezera pamafakitale zokutira, kupanga mapepala, ndi zoumba kuti zithandizire kukana moto komanso kukhazikika kwazinthu.

Mwachidule, magnesium hydroxide, chifukwa cha kusinthasintha kwake, ili ndi chiyembekezo chochulukirapo pakuchepetsa kwamoto, mankhwala, kuteteza chilengedwe, komanso kupanga mafakitale. Ndi kuchuluka kwa zofunikira zoteteza chilengedwe, mawonekedwe ake ngati mankhwala obiriwira adzakhala ofunika kwambiri.
