Polimbikitsa kuuma zosakaniza A njira ya

Simenti - ndi chosakhala binder zachilengedwe zochita kupanga. Mmodzi wa zikuluzikulu ndi yaikulu zomangira. Powonjezera njira madzi kapena amadzimadzi mchere, kapena zakumwa zina, n'kupanga kusakaniza pulasitiki chomwe pambuyo ikamauma kupanga olimba. Agwiritsidwa chuma nyumba kuti kupanga konkire ndi osiyanasiyana mortars. Ndi mwapadera kwa zipangizo zina mchere kumangako (laimu kapena gypsum) alimbitse kwathunthu panja. Pa mphamvu ya chuma kugawidwa ndi zizindikiro, zimene m'kukoma manambala 100 mpaka 600, kutanthauza compressive mphamvu ya 10 - 60 MPa. Zofunika kalasi 600 amatchedwa "asilikali" chifukwa cha mphamvu zawo ndi munda wa ntchito (kumangira nyumba nkhondo), ndiponso ndalama mtundu zambiri 500. Today, chuma chimenechi magulu (30 mpaka 60), zomwe zikusonyeza mphamvu compressive (MPa). Chachikulu kusiyana kwa zopangidwa kuti kukana si monga zikutanthauza nafunsa zosachepera 95% ya quality, ndiko, 95 za mfundo 100 ayenera kukumana kalasi.

Ndi zonse kupanga, simenti amapangidwa mwa umapezeka wabwino kwambiri wa gypsum ndi chibanthu. Njerwa mu nkhani iyi zotsatira za calcining homogeneous pamaso sintering osakaniza kwenikweni amene wapangidwa ndi dongo mu zikuchokera ndi wapamwamba kashiamu silicate ndi laimu. Pamene kugaya chibanthu chitaya gypsum kuti kusintha nthawi oipa, 15% mchere zinchito zina (galasi, phulusa, fumbi flue, mchenga ndi zina zotero. PA) kuti kusintha katundu wina, ndi kutsitsa mtengo wa zinthu koyamba. Kuwombera osakaniza kuyambira ikuchitika pa kutentha 1470 ° C ndi nthawi ya 2 - 4 ola yaitali ng'anjo wapadera ndi zipangizo kuwombola Integrated kutentha lakonzedwa kuti magawowa kaphatikizidwe oyenera mchere simenti masanjidwewo.

Amadziwika kuti simenti - imaphunzitsa, popanda zomwe ndi mbali ya lero nyumbayi. Mmene zabwino chifuniro anamanga ndithudi, izo zimatengera mwachindunji pa kuchuluka chidwi, makamaka opanga galimotoyo khalidwe kumanga mfundo. Ngakhale zikuoneka olakwika kuti apamwamba osakaniza simenti ayenera kuyamikiridwa uchitsiru mtengo, si kukhala wokwera kuposa. Tsopano, pa nthawi yovuta kwambiri, opanga ndi ogulitsa akuyesera kuti dongosolo rastsenochnuyu yabwino kwambiri ku mbali zonse ziwiri, kuti asunge kufunika ndi mpikisano, ndi ubwino ndi zina si wochepa ndi mfundo European, ngakhale mkulu-chatekinoloje kupanga kuchepa kwambiri expendable. Pali ngakhale chakuti osakaniza simenti, imene ndi mbali yapadera. osakaniza anali amaimira zizindikiro payekha: B - mofulumira kuyanika; C - sulphate ndi H - osakaniza, zochokera mwala zikuchokera dekhetsa (dekhetsa).

mphamvu simenti oyambirira amakhala ndi kukula kwa kukana yogwira mu nthawi yoyamba ya oipa. Anagwiritsa ntchito makamaka kupanga precast zomera konkire ndi mankhwala. Mkulu mawotchi kudalilika pa chiyambi cha kutsanulira zalongosoledwa bwino ndi mchere zikuchokera zina chibanthu kapangidwe kukula ndi fineness. Sulphate kapena osakaniza a Portland simenti sulphate ndi kutchula wamba Portland simenti ali kulimbikira apamwamba madzi saline, wosakwiya zowalamulira mwamphamvu ndi mkulu ozizira kukana. Konkire kuyenda ndi ndege amaika mumsewu, nyumba mlatho ayenera kugwiritsa ntchito simenti osakaniza anapangidwa pamaziko a chibanthu dekhetsa.
