Polycarboxylate Superplasticizer PCEwapangidwa ndi ma macromolecular mankhwala ndi magulu a sulfonic acid, magulu carboxyl, amino magulu, ndi polyoxyethylene mbali unyolo, etc., mu njira amadzimadzi, kudzera mfundo ya free radical copolymerization kaphatikizidwe wa ma polima okhala ndi chisa kapangidwe Surfactant.

Waukulu zopangira zofunika kaphatikizidwe waMankhwala opangira Madzi ochepetsa Polycarboxylate Superplasticierndi: 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, etc. mu polymerization ndondomeko ndi: oyambitsa persulfate ofotokoza , Benzoyl peroxide, azobisisobutyl cyanide;ma chain transfer agents: 3-mercaptopropionic acid, mercaptoacetic acid, etc.

Polycarboxylic acid kuchepetsa wothandizila madzi kaphatikizidwe njira ndi: mu botolo pansi wozungulira okonzeka ndi chipwirikiti magetsi, thermometer, chipangizo dontho, ndi condenser reflux, ndi polymerization monoma njira ndi initiator njira pang'onopang'ono anawonjezera dropwise ndi njira Kutenthetsa mu osamba madzi.Posankha polymerization monomer , Yunivesite yomwe ili ndi mpikisano wake iyenera kuganiziridwa bwino.The kutentha anachita angadziŵike molingana ndi enieni anachita monomer mtundu.Nthawi zambiri, kutentha kwa 70 ~ 95 ℃ kumatha kusankhidwa ngati kutentha komwe kumachitikira.

Ponyani yankho la monomer mkati mwa ola limodzi, ndikuponya mkati mwa mphindi 20 onjezani njira yoyambira yotsalira, ndipo pomaliza muonjeze kutentha ndi 5 ° C, pitilizani kuchitapo kanthu kwa 1h, ndipo kutentha kumatsikira ku 40 ° C, chepetsani ndikusintha. kutulutsa.
