Ukuhlukaniswa kwezingxube zekhonkrithi:
1. I-Admixtures yokuthuthukisa izakhiwo ze-rheological zezingxube zekhonkrithi, kuhlanganise nezinciphisi zamanzi ezihlukahlukene, ama-air-entraining agents kanye nama-pumping agents.
2. Izixube zokulungisa isikhathi sokusetha kanye nezakhiwo eziqinisayo zikakhonkolo, okuhlanganisa ama-retarders, ama-ejenti anamandla okuqala kanye nama-accelerator.
3. I-Admixtures yokuthuthukisa ukuqina kokhonkolo, okuhlanganisa ama-air-entraining agents, ama-agent okuvimbela amanzi kanye nama-rust inhibitors, njll.
4. Izixube zokuthuthukisa ezinye izakhiwo zikakhonkolo, okuhlanganisa ama-ejenti afaka umoya-mpilo, ama-expansion agents, ama-antifreeze agents, ama-colorants, ama-ejenti angangeni amanzi kanye nama-pumping agents, njll.
Isinciphisi samanzi:
I-ejenti yokunciphisa amanzi isho ingxube engagcina ukusebenza kukakhonkolo kungashintshile futhi inciphise ngokuphawulekayo ukusetshenziswa kwayo kwamanzi okuxutshwa.Njengoba i-ejenti yokunciphisa amanzi yengezwa endlini yokuxuba, uma ukusetshenziswa kwamanzi kweyunithi kungashintshiwe, ukusebenza kwayo kungathuthukiswa kakhulu, ngakho-ke i-ejenti yokunciphisa amanzi ibizwa nangokuthi i-plasticizer.
1. Indlela yokusebenza ye-ejenti yokunciphisa amanzi Ngemva kokuba usimende uhlanganiswe namanzi, izinhlayiya ze-samente zizodonselana futhi zenze ama-flocs amaningi emanzini.Esakhiweni se-floc, amanzi amaningi okuxuba ahlanganiswe, ukuze lawa manzi angakwazi ukudlala indima yokwandisa uketshezi lwe-slurry.Lapho i-ejenti yokunciphisa amanzi ingeziwe, i-ejenti yokunciphisa amanzi ingakwazi ukuhlakaza lezi zakhiwo ezinyakazayo futhi ikhulule amanzi angenalutho ahlanganisiwe, ngaleyo ndlela ithuthukise uketshezi lwengxube.Ngalesi sikhathi, uma ukusebenza kokhonkolo kwasekuqaleni kusadingeka kugcinwe kungashintshiwe, amanzi okuxuba angancishiswa kakhulu futhi umphumela wokunciphisa amanzi ungafinyelelwa, ngakho-ke kubizwa ngokuthi i-ejenti yokunciphisa amanzi.
Uma amandla ehlala engashintshile, inani likasimende lingancishiswa ngenkathi kuncishiswa amanzi ukuze kufezwe injongo yokonga usimende.
2. Imiphumela yobuchwepheshe nezomnotho yokusebenzisa i-ejenti yokunciphisa amanzi inemiphumela elandelayo yobuchwepheshe nezomnotho
a.Inani lamanzi okuxuba lingancishiswa ngo-5 ~ 25% noma ngaphezulu lapho ukusebenza kungashintshile futhi nenani likasimende lingancishiswa.Njengoba isilinganiso samanzi-samente sincishiswa ngokunciphisa inani lamanzi okuxuba, amandla angakhuphuka ngo-15-20%, ikakhulukazi amandla okuqala athuthukiswa kakhulu.
b.Ngaphansi kwesimo sokugcina isilinganiso sokuqala sokuxuba singashintshiwe, ukuwohloka kwengxube kungandiswa kakhulu (100 ~ 200mm kungandiswa), okwenza kube lula ukwakhiwa nokuhlangabezana nezidingo zokupompa ukwakhiwa kukakhonkolo.
c.Uma amandla nokusebenza kugcinwa, usimende ungasindiswa ngo-10 ~ 20%.
d.Ngenxa yokunciphisa inani lamanzi okuxuba, ukuphuma kwegazi nokuhlukaniswa kwengxube kungathuthukiswa, okungathuthukisa ukumelana nesithwathwa nokungangenisi kokhonkolo.Ngakho-ke, ukuqina kokhonkolo osetshenzisiwe kuzothuthukiswa.
3. Izinciphisi zamanzi ezisetshenziswa kakhulu njengamanje
Ama-ejenti okunciphisa amanzi ikakhulukazi ahlanganisa uchungechunge lwe-lignin, uchungechunge lwe-naphthalene, uchungechunge lwe-resin, uchungechunge lwe-molasses nochungechunge lwe-humic, njll. umsebenzi oyinhloko.I-ejenti yokunciphisa amanzi, i-ejenti yokunciphisa amanzi efaka umoya, njll.
