Cement Aluminous: Halabuurka, astaamaha, codsiga

Mid ka mid ah ugu baahan yahay iyo qalabka ugu muhiimsan in dhismaha cement ah. Waxa loo isticmaalaa soo saaridda of asbestos-cement, la taaban karo oo xoojiyay xubno la taaban karo, hoobiye. By cement waxaa loogu tala galay koox ka mid ah wakiilada qabanaya Haydarooliga, kuwaas oo qayb salka yihiin aluminates iyo silicates loo sameeyay inta lagu guda jiro howsha alaabta ceeriin ee heerkul sare iyo hoos u dhigay xaabo uu dhammaystiran ama qayb ahaan.

Features Halabuurka

Loo isticmaalaa sidii wax cayriin nuuradda oo saafi ah, bauxite. Arintaan waa dhagaxa, oo ka kooban nijaasta iyo hydrates. Bauxite helay baahsan oo duurka ku warshadaha wax soo saarka ee adsorbents, refractories, aluminium iyo kuwa kale.

cement aluminous kala duwan ku badan yihiin Odnokaltsievy Clinker aluminate ee ka kooban, go'aaminta sifooyinka ugu muhiimsan ee gal ah. Sidoo kale waxaa ku jira gehlenite sida nijaasta waaya'aragnimo iyo silicate dicalcium, sifo ka mid ah taas oo ah engegnaantooda gaabis ah.

Marka qasmay biyo bilaabaa inuu hydrate aluminate Odnokaltsievy. Walxaha loo sameeyay waqti isku mid ah ugu adeegaan sida qeyb ka mid ah waxyaabaha la bedesheen. Ballaarinta cement bilaabo inuu qarka u 45-60 daqiiqo ka dib, solidification dhamaystiran dhacdaa 10 saacadood ka dib. Suurto gal ah in la beddelo muddo goobta, Intaa waxaa dheer ee Sheelare (gypsum, lime), ama retarders (chloride calcium, boric acid).

sifooyinka

cement Aluminous waa awooda yar in deform, sida sameynta dhagax leeyahay qaab-dhismeedka aan dhab ahayn. Intaa waxaa dheer, jiritaanka monoaluminate cubic biyuhu uga xayuubiyay mass ee dhismaha.

Dabeecad loogu talagalay wax ka soo laabtay qadar badan oo kulaylka ka dhacaya saacadaha yar oo qalbi engegnaantooda aawadeed ugu horeysay. Habkaani waa mid waxtar leh marka uu wadaa hawl la taaban karo ee xilliga qaboobaha, laakiin waqti isku mid ah yaraynaysaa kala duwan ee loo isticmaalo waayo dhismeedka weyn.

Ballaarinta cement of alumina ka dhigay, waxaa loola jeedaa tirada qalabka dab u adkaysta. Waxa loo isticmaalaa formation of xal xiraan hydraulically madax adkaadeen oo kaashanaya, kuwaas oo ka kooban madax adkaadeen sidii chamotte, ore, magnesite.

Intaa waxaa dheer, muujinta ah ee kala duwan waa dhagax cement xoog sare, go'aamiso iska caabin weyn oo ka dhan ah saliidaha, acids, biyaha badda.

Macluumaadkaan waxaa awood u helo hoobiye oo la taaban karo la iska caabin ah oo badan si ay u qoyaan iyo cufnaanta. Laakiin waa u nugul burburinta degdeg sarkhaansan alkali iyo ammonium cusbada.

wax soo saarka

cement Aluminous waxaa soo saaray by laba hab: by calcining hor sintering iyo barafka Dufcaddii ceeriin. Habkaan dambe u baahan yahay diyaarinta amarka, barafku raacay by qaboojinta, burburin iyo ku shiidi. habka qalajiyo oo foorno lagu gartaa qaybaha asalka ah, sii darane aad u wanaagsan oo la isku qasin ilaa iyo homogenizing direyska, ka dibna granulated ama isku dar budada ah la ceyriyay bishii Foornooyinka ee noocyada kala duwan. Ka dib markii wax la qaboojiyey iyo isuku.

Cement Stone keensataa xoog yar la sii kordhaya heerkulka solidification recrystallization hydroaluminate sabab. waxyaabaha Sidaas daraaddeed ma sakhiray in autoclave daaweynta iyo cabaya.

Adkaan aan degdeg ah ka yar dhacdaa marka heerkulku hoose. Haddii tiro la qaboojiyey in qiimaha negative noqon lahaa mid aan suurta galayn in ay daaweeyaan biyo, oo u baahan dayactir ah xaaladaha heerkulka ku habboon.

noocyada cement aluminous

Waxaa jira 2 nooc oo ah wax: caadiga ah iyo sare cement alumina. Waxaa go'aan ku ganaya maalintii saddexaad ka dib markii wax soo saarka ee shaybaarka. Marka la eego qiimaha sare iyo la'aanta cement wax cayriin waa la ogaaday in mugga yar. maaddadu ay tahay budada fiican ee cagaaran madow, brown ama midab madow ah. Cement, cement aluminous, kuwaas oo qiimo bilaabataa at 40 rubles halkii kg, buuxiyey oo ku yaal weel iyo bacaha 50 kg. Awoodda in ay si deg deg ah ku shub biyaha waa dabeecadda ugu muhiimsan.

codsiga

Waxa loo isticmaalaa sameynta qaabab la taaban karo oo ay sii xoojiyeen halkaas oo la taaban karo ay tahay in la gaaro xoog design ee 1, 2 ama 7 maalmood, iyo sidoo kale dhismaha xarumaha dhulka hoostiisa iyo xeebaha u baahan sulphate sare. Waxaa xusid mudan oolnimada sare ee soo kabashada ee buundooyinka iyo dhismayaasha, formation degdeg ah aasaaska baabuurta iyo dhaawac seal ee gaadiidka badda.

Aluminous cement GC 40 ayaa laga helay codsiga in la abuuro of ballaarinta darey - waa non-yaraanaya biyuhu, balaarinta biyuhu iyo ballaarinta cement, cement aluminous.

Features faa'iido leh

gal cement Aluminous waa shay adag, oo loo isticmaalo kulaylka u adkaysta madaafiic, kuna waari dhexdeeda solidification degdeg ah hawada iyo biyaha. Waxaa la aasaasay by hab wanaagsan ku shiidi dar ceeriin la content sare ah alumina oo gubay in fusing ama sintering. Cayrinta waa la fuliyay ayaa maanta inta badan ee korontada ama foornada qaraxa gobolka barafku. Ma aha lagama maarmaan in darane xoogan oo maaddooyinka cayriin, iyo awood u leeyihiin in ay ka saarto silica iyo bir.

Noocyada alaabta cement aluminous siiyo kordheen caabiga ee xeryahooda noqde, cusbada, jėrto, baaruud iyo in la kordhiyo iska caabin ah heerkulka ilaa 1700 digrii ah.

Intaa waxaa dheer, saameynta biyaha macdanta waa la dhimay sabab u adagtahay ee formation of hydrate calcium by ficil leh dhexdhexaad ah aqueous. Resistance si sulfate daxalka waa la helay ay sabab u tahay maqnaanshaha hydroaluminate nooca tricalcium ah. Cement bandhigi Burburiyaan meel xumadoodu, xal u xoog of sulfate magnesium iyo warbaahinta acidic firfircoon.
