Aluminous cement: mejupụtara, àgwà, ngwa

Otu n'ime ndị kasị mkpa na ihe ndị kasị mkpa ihe na ndị na-ewu a ciment. Ọ na-eji maka imewe nke Asbestos-ciment, ihe na mesikwuru ihe ọcha, ogbunigwe. Site cement a pụtara a ìgwè nke haịdrọlik adịgide adịgide mmadụ, nke ndị isi òkè bụ aluminates na silicates ii n'oge nhazi nke ngwaọrụ na a elu okpomọkụ na-ebelata ka zuru ezu ma ọ bụ ele mmadụ anya n'ihu agbaze.

Eji dị ka akụrụngwa dị ọcha nkume nzu na bauxite. Nke ikpeazụ bụ na nkume, nke na-emi esịnede adịghị na hydrates. Bauxite nweela ebe nile na ulo oru ubi n'ihi na mmepụta nke adsorbents, Refractories, aluminum na ndị ọzọ.

aluminous cement iche predominance Odnokaltsievy aluminate clinker na mejupụtara, ikpebi isi e ji mara nke nragide. Ọzọkwa nwere gehlenite dị ka ụgbọ dị arọ adịghị na dicalcium silicate, a mara nke bụ onye na-adịghị hardening.

Mgbe weere mmiri amalite hydrate Odnokaltsievy aluminate. Bekee na-guzobere na n'otu oge ahụ na-eje ozi dị ka akụkụ nke sikwuo ike ihe. Ịmụba cement amalite ka mgbe 45-60 nkeji, a zuru ezu solidification emee mgbe 10 awa. Omume na-agbanwe ọnọdụ oge, na mgbakwunye na nke accelerators (gypsum, wayo), ma ọ bụ retarders (calcium chloride, boric acid).

e ji mara

Aluminous cement bụ a ala ike deform, dị ka akpụ nkume nwere a Ntụ Ọdịdị. Ke adianade do, ọnụnọ nke hydrated cubic monoaluminate na-eduga ná ọnwụ nke uka na guzobere.

E ji mara maka ihe laghachi nnukwu ego nke okpomọkụ aa na mbụ awa ole na ole nke hardening. Nke a na atụmatụ bara uru mgbe arụ ihe na-arụ ọrụ n'oge oyi, ma n'otu oge ebelata nso nke ojiji maka na oke owuwu.

Ịmụba cement mere nke alumina, ọ na-ezo ka ọnụ ọgụgụ nke ọkụ na-apụghị irepịa. Ọ na-eji maka guzobere refractory hydraulically solidifying ngwọta na njikọ na ndị a refractory mmiri ka chamotte, ore, magnesite.

Ke adianade do, akụkụ pụrụ iche bụ cement nkume na elu ike, na-ekpebi a ịrịba eguzogide megide mmanụ, asịd, oké osimiri mmiri.

Nke a ihe onwunwe bụ ike nke na inweta ngwa agha na ihe na a bukwanu iguzogide mmiri ma njupụta. Ma, ọ bụ ewekarị ngwangwa mbibi n'okpuru nduzi nke alkali na ammonium salts.

Aluminous cement nragide bụ a siri ike umi, na-eji na-okpomọkụ na-eguzogide ogbunigwe, ebe ngwa ngwa solidification ikuku na mmiri. Ọ na-kpụrụ site ezi egweri raw ngwakọta na a elu ọdịnaya nke alumina na ọkụ fusing ma ọ bụ sintering. Firing a rụrụ taa tumadi na electric ma ọ bụ gbawara ọkụ na-agbaze ala. Ọ dịghị mkpa na a siri ike na-egweri nke raw Efrata, na-enwe ike iji wepụ silica na ígwè.

Types of aluminous cement ngwaahịa nweta ụba iguzogide ogige starch, saline, lactic acid, sọlfọ na-amụba okpomọkụ na-eguzogide nke ruo 1700 degrees.

Ke adianade do, mmetụta nke ịnweta mmiri na-ebelata n'ihi na na-apụghị ime nke guzobere calcium hydrate site omume na otu okenye ọkara. Iguzogide sulfate corrosion na-enwetara n'ihi enweghị hydroaluminate tricalcium ụdị. Cement gụrụ corrode na alkaline ebe, a lekwasị ngwọta nke magnesium sulfate na-arụsi ọrụ ike acidic media.
