I-Cellulose Ether ye-Compounds yokuzilinganisa
Udaka lokuzilungiselela luwumkhiqizo ovikelekile onobuchwepheshe obuphakeme obunokuqukethwe okuphezulu kwezobuchwepheshe kanye nezixhumanisi zobuchwepheshe eziyinkimbinkimbi. Kuyinto ehlanganisiwe ye-powdew ehlanganisiwe eyakhiwa izithako eziningi, ezingasetshenziswa ngokuxuba amanzi esizeni. Ngemuva kokusakazeka okuncane kwesikhafu, ungathola izinga eliphakeme lendawo eyisisekelo. Usimende ozimilekile unesivinini esisheshayo esisheshayo. Ingahanjiswa ngemuva kwamahora angama-4-5, futhi ukwakhiwa komhlaba (okufana nokuphansi kokhuni, ibhodi yedayimane, njll.) Kungenziwa ngemuva kwamahora angama-24. Ukwakhiwa okusheshayo nokulula akunakuqhathaniswa yimikhawulo yendabuko yendabuko.
Usimende ozimilekile / udaka ngodaka luhlobo lomhlaba oyisicaba futhi obushelelezi obungabekwa ngesendlalelo sokugcina sokugcina (njengekhaphethi, phansi ngokhuni, njll.). Izidingo zalo ezibalulekile zokusebenza zifaka phakathi kanzima kanye nokushiswa okuphansi. Kunezinhlelo ezahlukene zaphansi emakethe, njenge-CEAND-based, Gypsum-based noma izingxube zabo.
Izakhiwo Eziyinhloko Zobuchwepheshe Zosimende Wezinga / Isilondolozi
(1) I-Liquidity
I-Fluidity iyinkomba ebalulekile ekhombisa ukusebenza kosimende / ngodaka olusezingeni eliphezulu. Ngokuvamile, uketshezi lukhulu kune-210 ~ 260mm.
(2) Ukuqina okumnandi
Le nkomba ikhombisa ukuqina kwesimende / udaka ngodaka. Thela ama-slurry ahlanganisiwe epuletini yengilazi ebekwe ngokuqondile, futhi ugcine ngemuva kwemizuzu engama-20. Akufanele kube nokuphuma kokopha okusobala, ukunxusa, ukuhlukaniswa, noma ukuguquka kwe-bubble. Le ndex inomthelela omkhulu esimweni sokuqina nokuqina kokubumba ngemuva kokubumba.
(3) Amandla acindezelayo
Njengezinto zaphansi, le ndex kufanele ihlangabezane nezincazelo zokwakha eziphansi zikasimende. Isitezi esivamile sasekhaya esisesifundeni sasemanzini esiphansi sidinga amandla acindezelayo we-15mpa noma ngaphezulu, namandla acindezelayo ekhasi lekhonkolo likakhonkolo noma ngaphezulu.
(4) amandla aguqukayo
Amandla aguqukayo e-Industrial Welveling Centem / Saturn kufanele abe mkhulu kune-6MPA.
(5) Ukubeka isikhathi
Ngesikhathi sokusetha usimende / udaka ngodaka, ngemuva kokuqinisekisa ukuthi i-slurry ixubene ngokulinganayo, qiniseka ukuthi isikhathi sayo sokusebenzisa singabi nemizuzu engaphezu kwama-40, futhi ukusebenza ngeke kuthinteke.
(6) Ukumelana nomthelela
Usimende / udaka olusezingeni eliphezulu kufanele lukwazi ukubekezelela ukushayisana okubangelwa yizinto ezijwayelekile nezinto zokuhanjiswa, futhi ukumelana nomthelela womhlaba kufanele kube mkhulu noma ulingane ne-4 Joules.
(7) Gqoka ukumelana
I-Self-Level Cement / udaka kusetshenziswa njengento engaphezulu komhlaba futhi kufanele ibekezelele ithrafikhi evamile yomhlaba. Ngenxa yokugeleza kwayo
Ungqimba olucwebezelayo mncane, futhi lapho isisekelo somhlabathi siqinile, amandla ayo athwala kakhulu, hhayi kwivolumu. Ngakho-ke, ukumelana kwayo ukugqokwa kubaluleke kakhulu kunamandla ayo acindezela.
(8) Bonding amandla ashubile kungqimba eyisisekelo
Amandla eBonding phakathi kosimende / udaka ngodaka kanye nesendlalelo sesisekelo ahlobene ngqo nokuthi ngabe ama-slurry azokwenziwa futhi ahluthwe ngemuva kokuqina, okunomthelela omkhulu ekudalweni kwezinto ezibonakalayo. Enqubweni yokwakha yangempela, upende i-ejenti ebonakalayo yomhlabathi ukuyenza ifinyelele esimweni esifanele ngokwengeziwe ukwakhiwa kwezinto ezizimele. Amandla ebhondi athambile wezinto zokwengeza usimende ezifuywayo zivame ngaphezu kwe-0.8MPA.
(9) Ukumelana nokuqhekeka
Ukumelana nokuqhekeka kuyinkomba ebalulekile yokuzilinganisa usimende / udaka, futhi usayizi wayo uhlobene nokuthi impahla yokuziqhenya inemifantu, izimbobo, nokuchitha ngemuva kokuqina. Ukuhlolwa okulungile kokumelana nokuqhekeka kwezinto zokuzilinganisa kuhlobene nokuhlolwa okulungile kwempumelelo noma ukwehluleka kwezinto zokuzimela.
