Amava kwiMagnesium Hydroxide Application

Njengomathiriyeli obalulekileyo we-inorganic chemical ekrwada, i-magnesium hydroxide ibonisa ixabiso elikhethekileyo kukhuseleko lokusingqongileyo, amayeza, izixhobo kunye nezinye iinkalo. Emva kweminyaka yophononongo olusebenzayo, amava ayo okusebenza aqinisekisa{1}}kuhlalutyo olunzulu.

Kummandla wokhuselo lokusingqongileyo, i-magnesium hydroxide isoloko isetyenziswa njengearhente yokucoca amanzi amdaka aneasidi ngenxa yealkalinity eyomeleleyo,-ityhefu, kunye nomthamo ophezulu wokubhengeza. Iimvavanyo zibonise ukuba isakhono sayo sokulungelelaniswa kwe-pH siphezulu kunekalika yesintu, kwaye isiphumo setyuwa se-magnesium sihluzwa ngokulula. Iplanti yokucoca i-electroplating isebenzise i-magnesium hydroxide ukuthothisa amanzi amdaka aneasidi, ukuzinzisa ukungcola kwe-pH ngaphakathi koluhlu lwe-6-9 kunye nokunyusa ukususwa kwesinyithi esinzima ngaphezu kwe-15%. Nangona kunjalo, ulawulo lwedosi ngononophelo lubalulekile. Idosi egqithisileyo inokunyusa ukuxinana kwe-ion ye-magnesium emanzini, okunokubangela iingxaki zokukala kwiinkqubo zonyango ze-membrane ezilandelayo.

Xa isetyenziswa njenge-antacid, iyeza{0}}yebakala le-magnesium hydroxide's buffering effect inokuphelisa ngokufanelekileyo iimpawu zegastric acid egqithisileyo. Xa kuthelekiswa ne-sodium bicarbonate, ayivelisi i-carbon dioxide gas, ngaloo ndlela inqanda umphumo wecala lokunyuka kwesisu. Abavelisi baye baxela ukuba ukulawula ubungakanani be-particle ukuya ngaphakathi kwe-5-10μm uluhlu luphucula kakhulu amaxabiso okuchithwa kweziyobisi, kodwa ukuguqulwa kwendawo kuyadingeka ukujongana ne-hygroscopicity.

Kwintsimi yezixhobo ezivuthayo zomlilo, i-magnesium hydroxide's thermal decomposition properties (ukubola kuqala kwi-340 degree, ukufunxa ukushisa) kwenza kube yinto efanelekileyo yokusingqongileyo i-flame retardant. Uvavanyo lwefomula yezinto zekhebula lubonise ukuba ukongeza i-50% ye-magnesium hydroxide yandisa isalathisi se-oksijini ukusuka kwi-22 ukuya kwi-34, kodwa unyango kunye ne-agent yokudibanisa i-silane yayifuneka ukuphucula ukuhambelana ne-substrate. Kwimveliso, kwafunyaniswa ukuba i-ultrafinely ground magnesium hydroxide ukuya ngaphantsi kwe-2μm ibonise ukusabalalisa okungcono, kodwa oku kubangele ukunyuka kwe-30% kwiindleko zamandla.

La mava esicelo abonisa ukuba ukusebenza kwe-magnesium hydroxide kuxhomekeke kakhulu kulawulo lwe-morphology, ukuguqulwa, kunye neeparitha zenkqubo ephuculweyo. Ngenkqubela phambili kwi-nanotechnology kunye ne-surface chemistry, amandla ayo okusebenza aya kuqhubeka nokwandisa.
