I-Cellulose ether Yezinhlanganisela Zokuzilinganisa
Udaka oluzilinganiselayo luwumkhiqizo wobuchwepheshe bokuvikela imvelo onokuqukethwe okuphezulu kobuchwepheshe kanye nezixhumanisi zobuchwepheshe eziyinkimbinkimbi. Kuyimpuphu exutshwe okomile ehlanganiswe izithako eziningi, engasetshenziswa ngokuxuba amanzi esizeni. Ngemuva kokusabalalisa okuncane kwe-scraper, ungathola izinga eliphezulu lesisekelo sesisekelo. Usimende ozilinganisa unejubane eliqina ngokushesha. Ingahanjwa ngemva kwamahora angu-4-5, futhi ukwakhiwa kwendawo (njengephansi lezinkuni, ibhodi ledayimane, njll) kungenziwa ngemva kwamahora angu-24. Ukwakhiwa okusheshayo nokulula akumataniswa nokulinganisa okujwayelekile okwenziwa ngesandla.
Usimende/udaka lokuzilinganisa uhlobo lwendawo ephansi eyisicaba futhi ebushelelezi engabekwa ngongqimba lokugcina (njengokhaphethi, phansi ngokhuni, njll.). Izidingo zayo zokusebenza ezibalulekile zihlanganisa ukuqina okusheshayo kanye nokuncipha okuphansi. Kunezinhlelo ezihlukene zaphansi emakethe, ezifana ne-cement-based, gypsum-based noma izingxube zazo.
Izakhiwo eziyinhloko zobuchwepheshe zikasimende/udaka lokuzilinganisa
(1) Ukuqina
Uketshezi luyinkomba ebalulekile ebonisa ukusebenza kukasimende/udaka lokuzilinganisa. Ngokuvamile, i-fluidity ingaphezu kuka-210 ~ 260mm.
(2) Ukuzinza kwe-slurry
Le nkomba ikhombisa ukuzinza kukasimende/udaka lokuzilinganisa. Thela i-slurry ehlanganisiwe epuleti lengilazi elibekwe endaweni evundlile, bese ubheka emva kwemizuzu engu-20. Akufanele kube khona ukopha okusobala, i-delamination, ukuhlukaniswa, noma ukuphenduka kwebhamuza. Le nkomba inomthelela omkhulu esimweni esingaphezulu kanye nokuqina kwempahla ngemva kokubunjwa.
(3) Amandla acindezelayo
Njengempahla yaphansi, le nkomba kufanele ihlangabezane nezimfuneko zokwakha izitezi zikasimende. Isitezi esingaphezulu sikasimende esijwayelekile sasekhaya sidinga amandla acindezelayo angu-15MPa noma ngaphezulu, futhi amandla acindezelayo ongqimba lukasimende olungaphezulu lukasimende angama-20MPa noma ngaphezulu.
(4) Amandla okuguquguquka
Amandla aguqukayo kasimende/udaka lokuzilinganisa ngokwezimboni kufanele abe mkhulu kuno-6Mpa.
(5) Ukubeka isikhathi
Ngesikhathi sokusetha sikasimende/udaka lokuzilinganisa, ngemva kokuqinisekisa ukuthi i-slurry ixubene ngokulinganayo, qinisekisa ukuthi isikhathi sokusebenzisa kwayo singaphezu kwemizuzu engama-40, futhi ukusebenza ngeke kuthinteke.
(6) Ukumelana nomthelela
Usimende/udaka oluzilinganisa ngokwalo kufanele lukwazi ukumelana nokungqubuzana okubangelwa ithrafikhi evamile nezinto ezihanjiswayo, futhi ukumelana komthelela komhlaba kufanele kube kukhulu noma kulingane nama-joule angu-4.
(7) Ukumelana nokugqoka
Usimende/udaka lokuzilinganisa lusetshenziswa njengendawo engaphezulu komhlaba futhi kumele imelane nokuhamba kwezimoto ezivamile. Ngenxa yokugeleza kwayo
Ungqimba oluyisicaba luncane, futhi lapho isisekelo somhlabathi siqinile, amandla ayo okuthwala angaphezulu kakhulu, hhayi kuvolumu. Ngakho-ke, ukumelana kwayo nokugqoka kubaluleke kakhulu kunamandla okucindezela.
(8) Ukubophela amandla okuqinile kungqimba oluyisisekelo
Amandla okubopha phakathi kukasimende/udaka lokuzilinganisa kanye nesendlalelo sesisekelo sihlobene ngokuqondile nokuthi ingabe udaka luzogoba futhi luxetshulwe ngemva kokuqina, okunomthelela omkhulu ekuqineni kwento. Enqubweni yangempela yokwakha, penda i-ejenti yokusebenzelana komhlabathi ukuze ifinyelele esimweni esifaneleka kakhulu ukwakhiwa kwezinto zokuzilinganisa. Amandla webhondi aqinile wezinto zokuzilinganisa usimende wasekhaya ngokuvamile angaphezu kuka-0.8MPa.
(9) Ukumelana nokuqhekeka
Ukumelana nokuqhekeka kuyinkomba eyinhloko yesimende/udaka lokuzilinganisa, futhi ubukhulu bayo buhlobene nokuthi impahla yokuzilinganisa inemifantu, imigodi, nokuchitheka ngemva kokuqina. Ukuhlolwa okulungile kokumelana nokuqhekeka kwezinto zokuzilinganisa kuhlobene nokuhlola okulungile kwempumelelo noma ukwehluleka kwezinto zokuzilinganisa.
