Polycarboxylate Superplasticizer PCEimapangidwa ndi ma macromolecular mankhwala okhala ndi magulu a sulfonic acid, magulu a carboxyl, magulu amino, ndi maunyolo am'mbali a polyoxyethylene, ndi zina zambiri, mu njira yamadzimadzi, kudzera mu mfundo ya kaphatikizidwe ka ma polima okhala ndi chisa cha 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 zozungulira okonzeka ndi chipwirikiti magetsi, thermometer, chipangizo dontho, ndi reflux condenser, ndi polymerization monoma njira ndi initiator njira ndi pang'onopang'ono anawonjezera dropwise ndi njira Kutentha 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.
