Aluminous ciminti: abun da ke ciki, halaye, da aikace-aikace

Daya daga cikin mafi zama dole, kuma mafi muhimmanci kayan a gina wani sumunti. Ana amfani ga yi na asbestos-ciminti, kankare da karfafa kankare abubuwa, rokoki. By ciminti da ake nufi wani rukuni na na'ura mai aiki da karfin ruwa nauyin jamiái, na da tushe rabo ne aluminates da silicates aka kafa a lokacin aiki na raw kayan a high zafin jiki da kuma rage ga cikakken ko m narkewa.

Features abun da ke ciki

Amfani da albarkatun kasa da tsarki farar ƙasa, kuma haƙar. A karshen ne a kan dutse, wanda aka hada da impurities da hydrates. Haƙar tsiwirwirinsu tartsatsi a cikin masana'antu filin domin samar da adsorbents, refractories, aluminum da sauransu.

aluminous ciminti bambanta predominance Odnokaltsievy aluminate clinker a cikin abun da ke ciki, tabbatas da babban halaye na m. Har ila yau, ya ƙunshi gehlenite kamar yadda ballast impurities kuma dicalcium silicate, a halayyar wanda shi ne jinkirin da hardening.

Lokacin da gauraye da ruwan ya fara hydrate Odnokaltsievy aluminate. Abubuwa suna kafa a lokaci guda da bauta a matsayin wani ɓangare na ƙarfafa abu. Fadada ciminti fara kafa bayan 45-60 minti, cikakken solidification auku bayan 10 hours. Zai yiwu ya canja saitin lokaci, Bugu da kari na accelerators (gypsum, lemun tsami), ko retarders (alli chloride, boric acid).

halaye na

Aluminous ciminti ne a low ikon deform, kamar yadda kafa dutse yana da m tsarin. Bugu da kari, gaban hydrated cubic monoaluminate take kaiwa zuwa asarar taro a cikin samuwar.

Halayyar ga kayan kõma manyan adadin zafi da ke faruwa a cikin ta farko 'yan sa'o'i na hardening. Wannan yanayin ne da amfani a lokacin dauke da fitar kankare aiki in winter, amma a lokaci guda rage kewayon amfani ga m Tsarin.

Fadada ciminti sanya alumina, shi yana nufin da yawan wuta-resistant kayan. Ana amfani da samuwar mai tsaurin hydraulically solidifying mafita a tare da wadannan tsaurin aka gyara kamar yadda chamotte, tama, magnesite.

Bugu da kari, da rarrabe ne ciminti dutse tare da high ƙarfi, da kayyade wani gagarumin juriya da mai, acid, teku ruwa.

Wannan abu ne iya samun turmi da kuma kankare tare da wani babba jure danshi da kuma yawa. Amma shi ne yiwuwa ga m halaka a ƙarƙashin rinjayar Alkali kuma ammonium salts.

samarwa

Aluminous ciminti ne kerarre ta hanyoyi guda biyu: ta calcining kafin sintering kuma dab raw tsari. Domin da karshen hanyar na bukatar shiri na cajin, narkewa bi ta sanyaya, crushing da nika. Tanda, bushewa Hanyar halin asali aka gyara, lafiya nika da hadawa har da wani uniform homogenizing, sa'an nan granulated ko powdered cakuda da aka kora a Tanderu iri-iri. Bayan da abu ne sanyaya kuma pulverized.

Siminti Stone yakan mallaki kasa karfin da kara solidification zafin jiki saboda hydroaluminate recrystallization. Saboda haka sanya kayayyakin ba hõre autoclave magani da kuma steaming.

Kadan m hardening auku a ƙananan yanayin zafi. Idan taro yana sanyaya zuwa korau dabi'u zai zama kusan ba zai yiwu a curing da ruwa, bukata kiyaye dace da zazzabi yanayi.

aluminous ciminti iri

Akwai 2 iri material: misali da babban alumina sumunti. M mark a rana ta uku bayan da samar da samfurori. Ganin high kudin da rashin ciminti albarkatun kasa da aka gane a cikin wani in mun gwada karamin girma. The abu ne mai lafiya foda na baki, ruwan kasa ko duhu kore a cikin launi. Sumunti, aluminous sumunti, wanda farashin farawa a 40 rubles da kg, cushe a kwantena da jakunkuna na 50 kg. A ikon da sauri zuba a cikin ruwa shi ne mafi muhimmanci halayyar.

aikace-aikace

Ana amfani da kafa karfafa kankare Tsarin inda kankare shi ne a cimma zane ƙarfi a 1, 2 ko 7 kwanaki, da kuma domin gina karkashin kasa da kuma teku da wuraren bukata high sulphate. Shi ne ya kamata a lura da high dace a dawo da gadoji da kuma gine-gine, m samuwar tushe ga motoci da hatimi lalacewa a Maritime kai.

Aluminous ciminti GC 40 ya samu ta aikace-aikace a cikin halittar fadada qagaggun - shi ne ba ƙunci hana ruwa, mai hana ruwa widening da kuma fadada sumunti, aluminous sumunti.

amfani Features

Aluminous ciminti m ne mai ɗamfarar abu, da kuma amfani da zafi-resistant rokoki, a cikinsa m solidification a iska da kuma a cikin ruwa. An kafa ta wajen lafiya nika raw cakuda da wani babban abun ciki na alumina kuma ƙone fusing ko sintering. Da harbe-harben ne da za'ayi a yau, yafi a lantarki ko tsãwa makera to da narkewa jihar. Ba lallai ba ne a wani karfi nika na raw sinadaran, kuma suna da ikon cire silica da na baƙin ƙarfe.

Iri aluminous ciminti kayayyakin goya ta ƙara juriya ga mahadi sitaci, Saline, lactic acid, sulfur da kuma kara yawan zafin jiki juriya har zuwa 1700 digiri.

Bugu da kari, da tasiri na ma'adinai ruwa an rage saboda da rashin yiwuwar samuwar alli hydrate ta maida martani da wani mai ruwa-ruwa matsakaici. Resistance zuwa sulfate lalata da aka samu saboda babu hydroaluminate tricalcium irin. Siminti fallasa corrode a wani alkaline yankin, a mayar da hankali bayani daga magnesium sulfate da kuma aiki acidic kafofin watsa labarai.
