Aikace-aikacen Aluminum Hydroxide

"Sinadarin alumina" yana nufin samar da sinadarin aluminum ingot banda alumina, aluminum oxide da aluminum hydroxide da aka bambanta ko samfuran da aka tsawaita. Akwai ɗaruruwan nau'ikan alumina masu sinadarai, kuma yana da nau'ikan aikace-aikace iri-iri a fannoni daban-daban. Wannan labarin zai gabatar da aikace-aikacen aluminum hydroxide da suka shafi hakan.

Hydroxide na aluminum, wanda aka fi sani da hydrated alumina, hydrous alumina, alumina hydrate, wani abu ne na amphoteric, wanda yake narkewa a cikin acid da tushe, wanda ba ya narkewa a cikin ruwa da barasa. Tsarin gabaɗaya shine Al2O3 • H2O tare da wurin narkewa na 300 (rashin ruwa). Dangane da yawan ruwan da ke cikinsa, ana iya raba jerin aluminum hydroxide zuwa: alumina trihydrate, alumina monohydrate, ƙarancin crystallinity alumina da amorphous aluminum hydroxide. An cire shi daga bauxite, ana iya yin sa daga gishirin aluminum da sodium hydroxide tare da ruwan ammonia. Akwai nau'ikan crystalline guda biyu da amorphous (gel).

Amorphous aluminum hydroxide sune ƙarancin alkali, ƙarancin ƙarfe, ƙananan ƙwayoyin cuta, da kuma fari mai yawa. Tsarin amfani yana da fa'idodin babban tauri, juriyar zafi, juriyar lalacewa, kwanciyar hankali mai kyau na sinadarai, ba mai guba ba, mara ɗanɗano, ba mai canzawa ba, bushewa da shaye-shaye lokacin da aka dumama samfurin amfani zuwa sama da digiri 250 na Celsius, kuma yana da kyakkyawan kawar da hayaki da kuma hana harshen wuta. Manyan wuraren amfani sune kamar haka.

Aluminum hydroxide wani nau'in cikawa ne mai tsabta wanda ba shi da sinadarai masu guba, ƙazanta ba ta da yawa, kuma jerin polymers ɗin da ke amfani da aluminum hydroxide a matsayin wakili mai cikewa sune polyurethane resin, epoxy resin, polyethylene, polypropylene, styrene butadiene roba, da sauransu. An yi amfani da aluminum hydroxide a matsayin mai hana harshen wuta da kuma rage hayaki tsawon shekaru da yawa a cikin resin da ba shi da cikakken abinci.

Tsarin hana harshen wuta don ƙara ATH zuwa polymer, rage yawan mai; aluminum hydroxide ya fara ne a 250 DEG C bushewar endothermic endothermic, hana hauhawar zafin polymer; rushewar tururin ruwa na narkewar iskar oxygen, ƙonewa a hankali; wajen samar da saman alumina mai ƙonewa zai iya hana ci gaba da amsawar ƙonewa.

Ana amfani da aluminum hydroxide a masana'antar shafa fenti don shafa saman, cikawa, da takarda mara ƙonewa. aluminum hydroxide na iya inganta sheƙi, haske, juriya ga haske, santsi da kuma iya bugawar takardar. Hakanan ana iya amfani da aluminum hydroxide a matsayin kayan da aka yi amfani da su don takarda mai rufi, kuma titania zai maye gurbin yumbu. Girman barbashi na aluminum hydroxide da aka saba amfani da shi shine 0.7-1.4 mu m.

Takardar hana wuta: maganin hana wuta, maganin kashe gobara, amma ba ya ƙonewa. An yi shi da takardar asbestos, ko kuma maganin kashe gobara tare da takardar da ta dace (kamar aluminum hydroxide) da magani.

Aluminum hydroxide ba shi da guba kuma ba shi da ɗanɗano, ba ya narkewa a cikin ruwa, kyakkyawan nau'in maganin gogayya ne mai tsaka-tsaki, maganin gogayya ne na gogayya na masana'antu na aluminum hydroxide Mohs. Taurin kai shine 2.5-3.5, tsarkin fiye da 99%, ƙimar pH 8.0-9.5, ƙimar D50 shine 8-15 micron, farashin matsakaici ne, kyakkyawan maganin gogayya ne na gogayya na gogayya na gogayya, fluoride da dacewa, kyakkyawan aiki. Yana ɗaya daga cikin ingantattun magungunan goge baki.

Mullite (ko mullite) jerin ma'adanai ne da suka ƙunshi aluminosilicate. Mullite ita ce kawai mahaɗin abubuwa biyu masu ƙarfi a cikin tsarin Al2O3 SiO2. Wannan nau'in ma'adinai yana da ƙarancin yawa. Wani nau'in mai hana ruwa gudu ne mai inganci, kuma ana iya samar da mullite ta hanyar dumama aluminum silicate ta hanyar wucin gadi. Ana amfani da Mullite galibi a cikin kayan hana ruwa gudu, yumbu, ƙarfe, siminti, lantarki da sauran masana'antu. Yana da halaye na juriya mai zafi, ƙarfi mai yawa da ƙaramin ƙarfin zafi.

Bugu da ƙari, ana iya amfani da aluminum hydroxide azaman marmara ta wucin gadi, agate ta wucin gadi, cika kafet; samar da aluminum sulfate, alum, alumina, hydrated alumina, kayan sinadarai na sodium aluminate samfuran roba; mai hana harshen wuta; ana amfani da shi azaman cikawa da kari na manne da sealants; sieve na ƙwayoyin halitta na roba; don maganin cututtukan ciki da sauransu.

Nau'in gel na aluminum hydroxide sune Aluminum Hydroxide Gel, boehmite, amorphous alumina. Yana da kyakkyawan manne, ƙirar ƙira, juriya ga zafin jiki mai yawa, ƙarfin zafi mai yawa, ƙarancin ƙarfin zafi, juriya ga tsatsa da iskar shaka, ƙarfi mai yawa da kuma saman santsi.

Ana iya amfani da aluminum hydroxide a matsayin babban sinadarin gel na ciki na aluminum wanda ke magance acid na ciki da na ciki, maganin gargajiya, shirye-shiryen sinadarai kamar su bitamin U da capsules na aluminum, Allunan Aluminum Hydroxide da sauran manyan abubuwan da ke cikinsa, kuma ana iya amfani da su don maganin cututtuka. Tsarin sinadarin anti-gastric acid shine Al (OH)3+6HCl=2AlCl3+3H2O. Ana iya amfani da alumina guda shida na ruwa da aka shirya daga aluminum hydroxide a matsayin maganin gel a fannin magani da kayan kwalliya.

Maganin saman da manne mai mannewa. Ana iya yin amfani da Gel ɗin Aluminum Hydroxide daga zare mara tsari ko na halitta, ta amfani da juriyar zafin jiki mai yawa da kuma ƙarewar saman, ana amfani da shi sosai wajen ƙera kayan aikin yumbu masu inganci, wanda kuma ake amfani da shi don ƙera faranti na lantarki; a lokaci guda kuma shine cikar inorganic.
