Polycarboxylate Superplasticizer PCEwaxa uu ka kooban yahay xeryahooda macromolecular la kooxaha sulfonic acid, kooxaha karboxyl, kooxaha amino, iyo polyoxyethylene silsilado dhinac, iwm, in xal aqueous, iyada oo mabda'a of free synthesis copolymerization polymers leh qaab-dhismeedka shanlo Surfactant.

Qalabka ugu muhiimsan ee looga baahan yahay isku-dhafkaKiimikada dhismaha Biyo-yareeya Polycarboxylate Superplasticierwaa: methacrylic acid, acrylic acid, ethyl acrylate, hydroxyethyl acrylate, sodium allyl sulfonate, methyl methacrylate, 2-acrylamido-2-methacrylic acid, methoxy polyoxyethylene methacrylate, ethoxy polyethylene glycol acrylate, iwm. habka polymerization waa: Initiators ku salaysan persulfate, Benzoyl peroxide, azobisisobutyl cyanide; wakiilada wareejinta silsiladda: 3-mercaptopropionic acid, mercaptoacetic acid, iwm.

Wakiilka yaraynta biyaha ee polycarboxylic acid Habka isku-dubaridku waa: weelka hoose ee wareegsan oo ku qalabaysan kiciya koronto, heerkulbeeg, qalab hoos u dhigaya, iyo qaboojiyaha reflux, xalka monomer-ka polymerization iyo xalinta bilawga ayaa si tartiib tartiib ah loogu daraa habka kuleylka biyaha qubeyska. Marka la dooranayo monomer-ka polymerization, Jaamacadda heerka tartankeeda waa in si buuxda loo tixgeliyo. Heerkulka falcelinta waxaa lagu go'aamin karaa iyadoo loo eegayo nooca monomer-ka falcelinta gaarka ah. Guud ahaan, heerkulka heerkulka kala duwan ee 70 ~ 95 ℃ waxaa loo dooran karaa sida heerkulka falcelinta.

Ku rid xalinta monomer hal saac gudaheed, ka dibna ku rid 20 daqiiqo gudahood ku dar xalinta soo hadhay, oo ugu dambeyntii ku kordhi heerkulka 5 ° C, sii wad falcelinta 1h, ka dib marka heerkulku hoos loo dhigo 40 ° C, dhexdhexaad ah dheecaan.
