I-Polycarboxylate Superplasticizer ikakhulukazi i-copolymerized by monomers unsaturated ngaphansi kwesenzo sabaqalisi, futhi amaketanga aseceleni anamaqembu asebenzayo axhunyelelwa ochungechungeni oluyinhloko lwe-polymer, ukuze ibe nemisebenzi yokusebenza kahle okuphezulu, ukulawula ukulahleka kokuwohloka nokumelana nokuncipha, futhi kungathinti ukuhlangana nokuqina kukasimende. Isinciphisi samanzi se-Polycarboxylic acid esisebenza kakhulu sihluke ngokuphelele ku-naphthalene sulfonate formaldehyde condensate NSF kanye ne-melamine sulfonate formaldehyde condensate ye-MSF yokunciphisa amanzi. Ingenza ukhonkolo wodaka ube noketshezi oluningi ngisho nangesilinganiso esiphansi, futhi unokubona okuphansi nokusebenza kokugcinwa kodoti ngesilinganiso esiphansi sikasimende wamanzi. Inokuhambisana okungcono kakhulu nosimende abahlukene futhi iyinto edingekayo ukuze kusetshenziswe ukhonkolo wodaka olunamandla futhi olunoketshezi oluningi.

I-Polycarboxylate Superplasticizer iyisizukulwane sesithathu se-high-performance chemical reducer yamanzi eyakhiwe ngemuva kwe-wood calcium ne-naphthalene water reducer. Uma kuqhathaniswa nesinciphisi samanzi esivamile, sinezinzuzo ezilandelayo:

a. Izinga eliphezulu lokuncishiswa kwamanzi: Izinga lokunciphisa amanzi le-polycarboxylic acid esebenza kahle yokunciphisa amanzi lingafinyelela ku-25-40%.

b. Izinga lokukhula kwamandla aphezulu: izinga eliphezulu lokukhula kwamandla, ikakhulukazi izinga eliphezulu lokukhula kwamandla okuqala.

c. Ukugcinwa kwe-slump enhle kakhulu: Ukusebenza kahle kokugcina ukuwohloka kungaqinisekisa ukulahlekelwa isikhathi esincane sikakhonkolo.

d. I-homogeneity enhle: Ikhonkrithi elungisiwe inoketshezi oluhle kakhulu, kulula ukuyithulula futhi ihlangene, futhi ifanele ukhonkolo ozimele kanye nokuzihlanganisa.

e. Ukulawulwa kokukhiqiza: Izinga lokunciphisa amanzi, ukugcinwa kwepulasitiki kanye nokusebenza kokufakwa komoya kwalolu chungechunge lwezinciphisi zamanzi kungalungiswa ngokulungisa isisindo samangqamuzana e-polymer, ubude, ukuminyana kanye nohlobo lwamaqembu amaketanga aseceleni.

f. Ukuguquguquka okubanzi: Ine-dispersibility enhle nokugcinwa kwe-plasticity ye-silicon ehlanzekile ehlukahlukene, i-silicon evamile, usimende we-slag silicate kanye nezingxube ezihlukahlukene zokwenza ukhonkolo.

g. Ukuncipha okuphansi: Kungathuthukisa ngokuphumelelayo ukuzinza kwevolumu kakhonkolo, futhi ukushwabana okungu-28d kokhonkolo okunciphisa amanzi okusekelwe ku-naphthalene kuncipha cishe ngo-20%, okunciphisa ngempumelelo ukulimala okubangelwa ukuqhekeka kukakhonkolo.

h. Okuluhlaza okotshani kanye nemvelo: akunabuthi, akugqwali, futhi akuqukethe i-formaldehyde nezinye izakhi eziyingozi.
