Ithonya okuqukethwe udaka esihlabathinii-polycarboxylate superplasticizerkuvame ukubulala, okusobala kakhulu kunochungechunge lwe-naphthalene kanye ne-aliphatic superplasticizers. Lapho okuqukethwe kodaka kukhula, ukusebenza kokhonkolo kuthuthukiswa ngokwandisa inanii-polycarboxylate superplasticizer, ngezinye izikhathi ngesigamu somzamo, futhi ngezinye izikhathi ukopha kuqala ngaphambi kokuba uketshezi lufinyelelwe. Lapho okuqukethwe kodaka kwe-aggregate yenhlawulo idlula ama-5%, izinga lokunciphisa amanzi likakhonkolo lixutshwei-polycarboxylate superplasticizerizokwehla, futhi ngisho
i-fluidity izolahleka ngokuphelele, futhi ukusebenza kokugcina okuwohlokayo nakho kuzoba kubi. Ngokuqukethwe kwe-powder yamatshe, kuyadingeka futhi ukwenza izivivinyo endaweni izikhathi eziningana ukuze ulawule okuqukethwe kwe-powder yamatshe, ukuze ukuzwela kulawulwe ngempumelelo, uketshezi lukakhonkolo kuqinisekiswe, kanye nokusebenza ukhonkolo kungenziwa elungiselelwe.
Ngenkinga yamanje yodaka, kunezixazululo eziningana ezivamile:
(1) Khulisa umthamo noma ukhuphule ingxenye ye-ejenti egcina ukuwohloka ekhishwa kancane, kodwa ulawule inani ukuze uvimbele izinkinga zokuba phuzi, ukopha, ukuhlukaniswa, ukubanjwa okuphansi kanye nesikhathi esibambekayo sokhonkolo sibe side kakhulu;
(2) Lungisa isilinganiso sesihlabathi noma ukhuphule inani lokungenisa umoya. Ngokwesisekelo sokuqinisekisa ukusebenza okuhle namandla, yehlisa izinga lesihlabathi noma ukhuphule inani lokungenisa umoya ukuze ufeze inhloso yokwandisa amanzi amahhala kanye nenani elidaka lesistimu kakhonkolo. ukulungisa izakhiwo zikakhonkolo;
(3) Engeza ngokufanelekile noma uguqule izingxenye ukuze uxazulule inkinga. Ukuhlola kubonise ukuthi ukwengeza inani elifanele le-sodium metabisulfite, i-sodium thiosulfate, i-sodium hexametaphosphate, ne-sodium sulfate kusinciphisi samanzi kunganciphisa ithonya lodaka okuqukethwe kukhonkolo ngokwezinga elithile.
Yiqiniso, lezi zindlela ezingenhla azikwazi ukuxazulula zonke izinkinga zodaka okuqukethwe, futhi umphumela wokuqukethwe kodaka ekuqiniseni ukhonkolo udinga ucwaningo olwengeziwe, ngakho-ke isisombululo esiyisisekelo siwukunciphisa okuqukethwe kodaka lwempahla eluhlaza.
