I-Polycarboxylate Superplasticizeribhekwa njengengxube esebenza kahle kakhulu. Abantu bahlale belindele ukuthi baphephe, basebenziseke kangcono, basebenze kahle futhi bazivumelanise nezimo kunengxube ye-naphthalene yendabuko ezinhlelweni zokusebenza, kodwa isimo sangempela asinjalo. Ihlangabezana nezinkinga ezahlukene. Ngakho-ke, yiziphi izinyathelo zokuphepha zokusetshenziswai-polycarboxylic acidizingxube?
1. I-Polycarboxylate Superplasticizeridinga ukulawula inani lamanzi ngokunengqondo. Ngakolunye uhlangothi, ukuze kuqinisekiswe isilinganiso se-water-binder, ngakolunye uhlangothi, ngobai-polycarboxylate superplasticizerizwela kakhulu ekusetshenzisweni kwamanzi. Izinkomba ezivame ukukhombisa ukusebenza kwezingxube zekhonkrithi zifaka uketshezi, ukubumbana nokugcinwa kwamanzi. Ngobai-polycarboxylate superplasticizerizwela kakhulu ekusetshenzisweni kwamanzi, ngezinye izikhathi ukusetshenziswa kwamanzi kukhushulwa kuphela ngo-1kg ~ 3kg phakathi nenqubo yokuhlola nokukhiqiza. Ukopha kakhulu, izinqwaba zamatshe avele obala, ukubamba okuphansi kusuka kumata, njll., akukwazi ukuqinisekisa ukufana kwengxube kakhonkolo. Ngakho-ke, ukusetshenziswa kwamanzi okuhlangene kufanele kulawulwe ngokuqinile ngesikhathi sokukhiqiza.
2. Lawula okuqukethwei-polycarboxylic acid. Okuqukethwe okunganele kukakhonkolo kubonakala ngokuwohloka ngokushesha, ukulahlekelwa okukhulu, nokungabi namanzi; kakhulu kuzodala ukopha okukhulu, ukuhlukaniswa, nokubamba phansi. Kuyadingeka ukwenza izivivinyo eziningi ukuze kutholwe ukulingana okuhle phakathi kokusetshenziswa kwamanzi kanyei-polycarboxylate superplasticizerokuqukethwe. Iphuzu, okungukuthi, ukusetshenziswa kwamanzi okuphelele kanye nomthamo we-admixture.
3. Akuvunyelwe ngokuphelele ukuxuba ama-naphthalene admixtures. Ngokusho kwamaphrojekthi ahlukene, izitshalo eziningi zokuxuba ukhonkolo zidinga ukusebenzisa i-naphthalene admixtures ngenkathi zisebenzisapce. Uma izimo zivuma, kungcono ukusebenzisa eziteshini ezihlukene. Uma iyunithi efanayo iqukethe kokubilii-polycarboxylate i-superplasticizerkanye ne-naphthalene, isitsha sokukala, ipayipi kanye ne-mixer yengxube kumele kuhlanzwe kahle uma kushintshwana kusetshenziswa, futhi ithangi likakhonkolo nalo kufanele lihlanzwe. Hlanza futhi ulayishe kabusha. Umai-polycarboxylic acidkanye nama-admixtures asekelwe ku-naphthalene axutshwe futhi asetshenziswe, lezi zingxube ezimbili zizosabela ukwenza ukhonkolo "usethe ngokushesha", okubangela ukuba yonke imoto ilahlwe.
4.Qinisa ukuhlolwa kwei-polycarboxylate superplasticizerizingxube. Ngenkathi uhlola ama-admixtures, thatha amasampula ezintweni ezingavuthiwe ezizosetshenziswa, futhi uhlole ukhonkolo ngokuya ngezidingo zobuchwepheshe zephrojekthi. Uma kukhona izinkinga ezitholakalayo, sicela ucele ngokushesha abasebenzi bezobuchwepheshe bomkhiqizi we-admixture ukuthi benze izinguquko.
Ngamafuphi, ukhonkoloinhlanganisela ye-polycarboxylic acidwuhlobo olusha lwezinto. Uma kuqhathaniswa nezinciphisi zamanzi zendabuko, ayinawo kuphela umthamo omncane uma kuqhathaniswa, izinga eliphezulu lokunciphisa amanzi, i-chlorine ephansi kanye ne-alkalinity ephansi, kanye nomphumela osobala wokugcinwa kokuwohloka. Thuthukisa ukuqina kwesakhiwo sikakhonkolo, kanye nenqubo yokukhiqizai-polycarboxylate superplasticizerisinciphisi samanzi sihlanzekile futhi asingcolisi. Iwuhlobo olusha lwesinciphisi samanzi esisebenza kahle esiluhlaza futhi esivumelana nemvelo.
