Yiziphi izici zePCE-based admixtures?

Izici zokunciphisa amanzi kakhulu:PCE-based izingxube ukusiza ukunciphisa amanzi ngokuvumela ukhonkolo ukugcina ukusebenza kwawo ngenkathi kunciphisa ukusetshenziswa kwamanzi. Lokhu kufezwa ngokusebenzisa ukwakheka kukasimende okuthe ukuphakama kanye nezinye izixube ukuze kwakhiwe imiksi eminyene.

PCE superplasticizers zivame ukusetshenziswa ekusetshenzisweni kokhonkolo okuxubile okulungele lapho kudingeka khona ukusebenza okuphezulu nokuqina.

Ukumelana okuphezulu: Izakhiwo zokumelana ne-admixture zivumela ukhonkolo ukuthi umelane nokuhlaselwa kwe-sulfate, ukulimala kweqhwa kanye nokusabela kwe-alkali-silica.

Ukunakekelwa kwe-Slump: Njengengxube ephumelelayo yokunciphisa amanzi,PCE admix kungasiza ukunciphisa amanzi adingekayo ukuze kuzuzwe ukuwohloka okunikeziwe ngokwenza ngcono ukusebenza kwengxube kakhonkolo. Lokhu kuvame ukufezwa ngokunciphisa isilinganiso sikasimende wamanzi nokwandisa ukusatshalaliswa kosayizi wezinhlayiyana. Ngakho-ke, lokhu kusiza ekuvimbeleni ukugeleza kwamanzi ngokweqile ngesikhathi sokuxuba, okungaholela ekulahlekelweni kwe-slump.

Izinzuzo zePCE-Isekelwe Admixture:

Ukusebenza okuthuthukisiwe:PCE-based izingxube hlinzeka ngezingxube zikakhonkolo ezisebenza kahle kakhulu ezinamandla aphezulu kanye nokusebenza okusheshisiwe ngaphandle kokuyekethisa izakhiwo zokumisa. Iphinde ithuthukise ukusebenza kukakhonkolo omusha, okwenza kube lula ukupompa nokubeka.

 Yehlisa ukuvuthwa: Izixube zinganciphisa ukungena kokhonkolo, ngaleyo ndlela kunciphise ingozi yomswakama ongena kukhonkolo.

 Izingxube zikakhonkolo ezisezingeni eliphakeme: Izixube ezisekelwe ku-perchlorethylene ziholela ekuxubeni okuhle kakhulu kukakhonkolo okuthuthukisiwe kukasimende kanye nezakhiwo zokuthulula. Lokhu kuthuthukisa amandla kanye nekhwalithi yekhonkrithi.

 Yehlisa ukushwabana: Izixube zikakhonkolo zinganciphisa ukushwabana kukakhonkolo, okusiza ukunciphisa ingozi yokuqhekeka kanye nomunye umonakalo. Lezi zingxube zinikeza ingxube kakhonkolo ngesistimu yokwelapha yangaphakathi. Ukuba khona kwe-polycarboxylate ethers kuvumela ingxube ukuthi imunce futhi igcine amanzi kungxube kakhonkolo.

 Isiphetho esithuthukisiwe:PCE-based izingxube ingathuthukisa isiphetho sikakhonkolo, ikwenze kube bushelelezi, kujabulise ngobuhle futhi kube nendawo engaguquki. Isiphetho esithuthukisiwe sisiza ukwandisa ukuqina kwendawo ekhonkolo. Le ngxube iphinde inikeze ukwakheka kokuxuba okufanayo futhi inciphise ukuthambekela kokuqhekeka kokuncipha. Ukwengeza, kungasiza ukunciphisa ukumuncwa kwamanzi futhi kumise ukugeleza kwamanzi.
