Ukumelana nokuhlakazeka kuyinkomba ebalulekile yezobuchwepheshe ukukala ikhwalithi ye-anti - ehlakazekile.Hydroxypropyl methyl celluloseiyingxenye ye-polymer encibilikayo yamanzi, eyaziwa nangokuthi i-resin engenamanzi noma i-polymer esolule. Kukhulisa ukungaguquguquki kwengxube ngokwandisa i-viscosity yamanzi okuxuba. Kuluhlobo lwe-hydrophilic polymer impahla, engachithwa emanzini futhi yakha isisombululo noma uketshezi olungafani. Izivivinyo zikhombisa ukuthi lapho inani le-Naphthalene System Superplastizer likhuphuka, ukwengeza kwe-superplastizer kuzonciphisa ukumelana nokuhlakazwa kosimende omusha. Lokhu kungenxa yokuthi i-naphthalalene chungechunge lokunciphisa amanzi aphezulu angelona eliphakeme le-ejenti elisebenzayo, lapho amanzi encoma i-ejenti efakwa ku-pement izinhlayiyana ezinamacala okukhishwa kosekhukhweni, asongelwe ukwakheka kokwehlukanisa, kuzodala ukulahleka kwengxenye kasimende. Ngasikhathi sinye, kutholakala ukuthi ngokwanda kokuqukethwe kwe-HPMC, ukuhlakazwa kwe-anti kodaka olusha lwamakhazithi kungcono futhi kungcono.
Izici Zokwenza ukhonkolo:
I-HPMC Underwater Admixive Admixture ahlukaniswayo eBridge Foundation Engineering ye-Expressway, kanye nebanga lamandla okuklama kwakungu-C25. Ngemuva kokuhlolwa okuyisisekelo, umthamo kasimende ngu-400kg, i-silica fuumule exubile ye-silica Feumu 25kg / M3,I-HPMCUmthamo omkhulu u-0.6% wemithamo kasimende, isilinganiso sokwenza amanzi ngamanzi singu-0.42, isilinganiso se-40%, i-Naphthalene Peater Ukunciphisa isivuno se-8%, i-aughtentite manzi yokuphakanyiswa komoya, i-aughtive specinen e-air 28.4MPA, Izinsuku, kanye nokulinganiselwa kwamandla kokhonkolo okwakhiwa emanzini kanye nokhonkolo owakhiwa emoyeni ngu-84.8%, kukhombisa umphumela obalulekile.
1. Ukungezwa kwe-HPMC kunomthelela wokubuyisa okusobala kwingxube yodaka. Ngokukhuphuka komthamo we-HPMC, isikhathi sokubeka udaka siyenzeka njalo ngempumelelo. Ngaphansi kwesimo esifanayo somthamo we-HPMC, isikhathi sokusetha sikadaka ngaphansi kwamanzi isikhathi eside kunomoya. Lesi sici sizuzisa ukupompa kokhonkolo ongaphansi kwamanzi.
2, ihlanganiswe ne-hydroxypropyllll methyl cellulose yodaka olusha lwamanzi lunobumbano oluhle, cishe akukho nto eyeding.
I-3, umthamo we-HPMC kanye ne-Mortar Water Funch yehle kuqala bese inyuke kakhulu.
4. Ukufakwa kwamanzi okunciphisa amanzi kuthuthukisa inkinga yokwanda kwesidingo samanzi sodaka, kepha kufanele kulawulwe kahle, ngaphandle kwalokho kuzonciphisa ukumelana kwamanzi angaphansi kwamanzi.
5. Unomehluko omncane esakhiweni phakathi kwe-HPMC ehlanganisiwe usimende ama-slurry slurry ama-slurry kanye nezinhlamvu ezingenalutho, futhi kunomehluko omncane kwisakhiwo nokuhlangana phakathi kwamanzi athululelwe usimende kanye nomoya othululelwe usimende othululelwe khona usimende nomoya othululelwe amanzi okomoya kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululwe usimende othululile usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululelwe usimende kanye nomoya othululelwe usimende othululile usimende. I-28D Underwater yokubumba i-specimen ikhululekile kancane. Isizathu esiyinhloko ukuthi ukungezwa kwe-HPMC kunciphisa kakhulu ukulahleka nokuhlakazeka kukasimende ngesikhathi sokuthela amanzi, kepha futhi kunciphisa izinga lokusebenzisana nosimende. Kuphrojekthi, ngaphansi kwesimo sokuqinisekisa umphumela ongaphansi kwamanzi, inani lokuxuba le-HPMC lincishiswa ngangokunokwenzeka.
6, engezaI-HPMCNgaphansi kwamanzi akasabalalisi ukuhlangana kukakhonkolo, alawule inani lamandla amahle, iphrojekthi yokushayela ibonisa ukuthi isilinganiso samandla sokwakha ukhonkolo emanzini nokwakhiwa komoya kungu-84.8%, umphumela ubaluleke kakhulu.
