Polycarboxylate Superplasticizer PCEyenziwe ngamaqela e-macromolecular kunye namaqela e-sulfonic acid, amaqela e-carboxyl, amaqela e-amino, kunye namatyathanga asecaleni e-polyoxyethylene, njl., kwisisombululo esinamanzi, ngomgaqo we-free radical copolymerization synthesis of polymers ene-comb structure Surfactant.

Eyona imathiriyeli ekrwada efunekayo ukuze kudityanisweIkhemikhali yokwakha Isinciphisi samanzi Polycarboxylate Superplasticierzezi: 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, njl ukuba i-beyl initiya acrylate, njl. kwinkqubo ye-polymerization zezi: abaqalisi be-persulfate-based based , i-Benzoyl peroxide, i-azobisisobutyl cyanide;i-agent yokudlulisa ikhonkco: i-3-mercaptopropionic acid, i-mercaptoacetic acid, njl.

I-arhente yokunciphisa amanzi e-polycarboxylic acid indlela yokuhlanganisa yile: kwiflaski esezantsi engqukuva enezixhobo zombane, ithemometha, isixhobo sokulahla, kunye necondenser ye-reflux, isisombululo se-polymerization monomer kunye nesisombululo se-initiator zongezwa kancinci kancinci ngendlela yokufudumeza kwindawo yokuhlambela amanzi.Xa ukhetha i-polymerization monomer , Iyunivesiti enezinga lokhuphiswano kufuneka ithathelwe ingqalelo ngokupheleleyo.Ubushushu reaction inokumiselwa ngokohlobo oluthile reaction monoma.Ngokubanzi, iqondo lobushushu kuluhlu lweqondo lobushushu 70~95℃ linokukhethwa njengobushushu bokusabela.

Yehlisa isisombululo se-monomer kwiyure enye, kwaye emva koko uyilahle ngaphakathi kwemizuzu engama-20 yongeza isisombululo esisele se-initiator, kwaye ekugqibeleni unyuse ubushushu nge-5 ° C, qhubeka nokusabela kwi-1h, kwaye emva kokuba iqondo lobushushu lehlisiwe ukuya kuma-40 ° C, nciphisa kwaye ukukhupha.
