Zochitika mu Magnesium Hydrooxide Applications

Monga chinthu chofunikira pakupanga mankhwala, magnesium hydroxide imawonetsa phindu lapadera pakuteteza chilengedwe, mankhwala, zida, ndi zina. Pambuyo pazaka zambiri zakufufuza, kugwiritsa ntchito kwake kumafunikira{1}}kuwunika mozama.

M'malo oteteza zachilengedwe, magnesium hydroxide imagwiritsidwa ntchito ngati acidic poyeretsa madzi atayira chifukwa cha kulimba kwake, -kawopsedwe, komanso kutsekemera kwambiri. Kuyesera kwawonetsa kuti luso lake losintha pH limaposa laimu wamba, ndipo chifukwa chake mchere wa magnesium umasefedwa mosavuta. Chomera chopangira ma electroplating chinagwiritsa ntchito magnesium hydroxide kuti achepetse madzi otayira acidic, kukhazikika pH yamadzi mkati mwa 6-9 ndikuwonjezera kuchotsedwa kwazitsulo zolemera ndi 15%. Komabe, kuwongolera mosamalitsa mlingo ndikofunikira. Mlingo wopitilira muyeso ukhoza kuwonjezera kuchuluka kwa ma magnesium ion m'madzi, zomwe zitha kubweretsa zovuta pamakina ochizira a membrane.

Akagwiritsidwa ntchito ngati antacid, pharmaceutical-grade magnesium hydroxide's mild buffering effect amatha kuchepetsa zizindikiro za m'mimba mwambiri. Poyerekeza ndi sodium bicarbonate, satulutsa mpweya woipa wa carbon dioxide, motero amapewa zotsatira za kuphulika kwa m'mimba. Opanga anena kuti kuwongolera kukula kwa tinthu mkati mwa 5-10μm kumathandizira kwambiri kuchuluka kwa mankhwala osokoneza bongo, koma kusinthidwa kwapamwamba kumafunika kuthana ndi hygroscopicity.

M'munda wa zinthu zoletsa moto, magnesium hydroxide's thermal decomposition properties (kuwola kumayambira pa 340 digiri, kuyamwa kutentha) kumapangitsa kuti ikhale yabwino kwambiri yoteteza lawi lamoto. Kuyesedwa kwa chilinganizo cha zinthu za chingwe kunawonetsa kuti kuwonjezera 50% magnesium hydroxide kumawonjezera index ya okosijeni kuchokera ku 22 mpaka 34, koma chithandizo ndi silane coupling agent chinali chofunikira kuti chigwirizane ndi gawo lapansi. Popanga, anapeza kuti ultrafinely pansi magnesium hydroxide kuti zosakwana 2μm anasonyeza dispersibility bwino, koma izi zinachititsa kuwonjezeka 30% ya ndalama mphamvu.

Zochitika pakugwiritsa ntchito izi zikuwonetsa kuti magwiridwe antchito a magnesium hydroxide amadalira kwambiri morphology control, kusinthidwa, ndi kukhathamiritsa magawo azinthu. Ndi kupita patsogolo kwa nanotechnology ndi pamwamba chemistry, kuthekera kwake kupitilira kukula.
