I-Polycarboxylate Superplasticizer PCEyakhiwe izinhlanganisela ze-macromolecular ezinamaqembu e-sulfonic acid, amaqembu e-carboxyl, amaqembu e-amino, namaketango aseceleni e-polyoxyethylene, njll., kusisombululo esinamanzi, ngomgomo we-free radical copolymerization synthesis yama-polymers anesakhiwo se-Surfactant.

Izinto zokusetshenziswa eziyinhloko ezidingekayo ukuze kuhlanganisweIkhemikhali yokwakha Isinciphisi samanzi iPolycarboxylate Superplasticieryilezi: i-methacrylic acid, i-acrylic acid, i-ethyl acrylate, i-hydroxyethyl acrylate, i-sodium allyl sulfonate, i-methyl methacrylate, i-2-acrylamido- 2-Methacrylic acid, i-methoxy polyoxyethylene methacrylate, i-ethoxy polyethylene glycol acrylate, njll. kwinqubo ye-polymerization yilezi: abaqalisi be-persulfate-based, i-Benzoyl peroxide, i-azobisisobutyl cyanide; ama-ejenti okudlulisa amaketanga: i-3-mercaptopropionic acid, i-mercaptoacetic acid, njll.

I-ejenti yokunciphisa amanzi ye-polycarboxylic acid Indlela yokuhlanganisa yilena: eflaskini engezansi eyindilinga efakwe i-stirrer kagesi, ithemometha, umshini wokuwisa, kanye ne-reflux condenser, isixazululo se-polymerization monomer kanye nesisombululo se-initiator zengezwa kancane kancane ngendlela yokufudumeza emanzini okugeza. Lapho ukhetha i-polymerization monomer , Inyuvesi enezinga layo lokuncintisana kufanele ibhekwe ngokugcwele. Izinga lokushisa lokusabela linganqunywa ngokusho kohlobo oluthile lokusabela kwe-monomer. Ngokuvamile, izinga lokushisa ebangeni lokushisa elingu-70~95℃ lingakhethwa njengezinga lokushisa lokusabela.

Yehlisa isixazululo se-monomer kungakapheli ihora elilodwa, bese uyiphonsa kungakapheli imizuzu engama-20 engeza isixazululo se-initiator esisele, futhi ekugcineni wandise izinga lokushisa ngo-5 ° C, qhubeka nokusabela kwe-1h, futhi ngemuva kokuthi izinga lokushisa lehlisiwe libe ngu-40 ° C, nciphisa futhi khipha.
