Polycarboxylate Superplasticizer PCEhe pūhui macromolecular me nga roopu waikawa sulfonic, nga roopu carboxyl, nga roopu amino, me nga mekameka taha polyoxyethylene, me etahi atu, i roto i te wairewa wai, na roto i te kaupapa o te whakahiatotanga copolymerization tuwhena kore utu o nga waerau me te hanganga heru Surfactant.

Ko nga rauemi mata matua e hiahiatia ana mo te whakahiato oHanganga matū Water reducer Polycarboxylate Superplasticierko: waikawa methacrylic, waikawa kiriaku, ethyl acrylate, hydroxyethyl acrylate, konutai allyl sulfonate, methyl methacrylate, 2-acrylamido- 2-Methacrylic acid, methoxy polyoxyethylene methacrylate, ethoxy polyethylene glycol acrylate, allyl ether, e taea te whakamahi. i roto i te tukanga polymerization ko: persulfate-based initiators , Benzoyl peroxide, azobisisobutyl cyanide;nga kaihoko whakawhiti mekameka: 3-mercaptopropionic acid, mercaptoacetic acid, etc.

Ko te kaihoko whakaheke wai waikawa polycarboxylic Ko te tikanga whakahiato he: i roto i te ipu porowhita o raro e mau ana ki te whakakorikori hiko, he inemahana, he taputapu whakataka, me te kaitao whakakorikori, ko te wairewa polymerization monomer me te wairewa whakauru ka ata taapiri ma te whakamahana i roto i te kaukau wai.I te wa e whiriwhiri ana i te polymerization monomer , Ko te whare wananga me tona reeti whakataetae me tino whakaaro.Ka taea te whakatau i te pāmahana tauhohenga kia rite ki te momo monomer tauhohenga motuhake.Ko te tikanga, ko te pāmahana i roto i te awhe pāmahana o 70 ~ 95 ℃ taea te tīpako rite te pāmahana tauhohenga.

Whakatakahia te wairewa monomer i roto i te haora kotahi, katahi ka maturuturu i roto i te 20 meneti ka tapirihia te toenga o te wairewa initiator, ka mutu te whakanui ake i te mahana ma te 5°C, ka haere tonu te hohenga mo te 1h, ka mutu te whakahekenga o te pāmahana ki te 40°C, ka whakakorea ka tukunga.
