Izici ze-ejenti yokunciphisa amanzi zithinta ngokuqondile ukusebenza kokunciphisa ukhonkolo.Ngaphansi kokuwohloka okufanayo kukakhonkolo, izinga lokushwabana kukakhonkolo nge-ejenti yokunciphisa amanzi licishe libe ngama-35% ngaphezu kwalokho kukakhonkolo ngaphandle kwe-ejenti yokunciphisa amanzi.Ngakho-ke, ukuqhekeka kukakhonkolo kungenzeka kakhulu.Nasi isizathu:
1. Umphumela wokunciphisa amanzi uncike kakhulu ezintweni ezingavuthiwe zikakhonkolo kanye nezilinganiso zokuxuba.
Izinga lokunciphisa amanzi likakhonkolo liyincazelo eqinile kakhulu, kodwa ngokuvamile libangela ukungezwani.Ezikhathini eziningi ezahlukene, abantu basebenzisa njalo izinga lokunciphisa amanzi ukuze baveze umphumela wokunciphisa amanzi womkhiqizo.
Ngesilinganiso esiphansi, ukuthatha i-ejenti yokunciphisa amanzi ye-polycarboxylate njengesibonelo, kuye kwafakazelwa ukuthi izinga layo lokunciphisa amanzi likhulu kakhulu kunezinye izinhlobo ze-ejenti yokunciphisa amanzi, futhi inomphumela ongcono wokunciphisa amanzi.Kodwa-ke, kufanele kuqashelwe ukuthi uma kuqhathaniswa namanye ama-ejenti okunciphisa amanzi, umphumela wokunciphisa amanzi we-polycarboxylate ama-ejenti okunciphisa amanzi uthinteka kakhulu yizimo zokuhlola.
Phakathi kwezinto ezithonya umphumela we-plasticizing we-polycarboxylate superplasticizer, izinga lesihlabathi nokuhlukaniswa kwezinhlayiyana zama-aggregate kukhonkolo nakho kunomthelela omkhulu.Uma kuqhathaniswa namanye ama-ejenti okunciphisa amanzi asebenza kahle kakhulu afana nochungechunge lwe-naphthalene, umphumela we-plasticizing we-polycarboxylate ama-ejenti okunciphisa amanzi uthintwa kakhulu okuqukethwe kodaka kwe-aggregates emihle.
2. Umphumela wokunciphisa amanzi uncike kakhulu kumthamo we-ejenti yokunciphisa amanzi.
Ngokuvamile, njengoba umthamo we-ejenti yokunciphisa amanzi ukhuphuka, izinga lokunciphisa amanzi likakhonkolo nalo liyakhuphuka, ikakhulukazi kuma-agent okunciphisa amanzi asekelwe ku-polycarboxylic acid, umthamo uthinta ngokuqondile umphumela wokunciphisa amanzi.
Kodwa-ke, kukhona okuhlukile ekusebenzeni okungokoqobo.Okusho ukuthi, ngemva kokufinyelelwa kwesilinganiso esithile, umphumela wokunciphisa amanzi "uyancipha" njengoba umthamo ukhula.Lokhu kungenxa yokuthi ngalesi sikhathi ingxube kakhonkolo iba lukhuni, ukhonkolo uhlushwa ukopha okukhulu, futhi uMthetho wokuwohloka awusakwazi ukuveza uketshezi kwawo.
3. Ukusebenza kwengxube yekhonkrithi elungiselelwe kuzwela kakhulu ekusetshenzisweni kwamanzi.
Izinkomba zokusebenza kwezingxube zikakhonkolo zivame ukuvela ezicini ezifana nokugcinwa kwamanzi, ukubumbana, kanye noketshezi.Ukhonkolo olungiselelwe kusetshenziswa ama-polycarboxylic acid-based superplasticizers awuhlali uhlangabezana ngokugcwele nezidingo zokusetshenziswa.Ukusebenza kwengxube yekhonkrithi elungiselelwe kuzwela kakhulu ekusetshenzisweni kwamanzi, futhi ezinye izinkinga zivame ukwenzeka.
