Polycarboxylate Superplasticizer PCEinoumbwa ne macromolecular compounds ane sulfonic acid groups, carboxyl groups, amino groups, uye polyoxyethylene side cheni, nezvimwewo, mune aqueous solution, kuburikidza nemusimboti wemahara radical copolymerization synthesis yemapolymer ane comb chimiro Surfactant.

Iyo huru mbishi zvinhu inodiwa pakugadzirwa kweKemikari yekuvaka Mvura inoderedza Polycarboxylate Superplasticierndeiyi: 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, nezvimwe zvinogona kushandiswa beyl initiorite. mu polymerization maitiro ndeaya: persulfate-based initiators , Benzoyl peroxide, azobisisobutyl cyanide; cheni kutamisa vamiririri: 3-mercaptopropionic asidhi, mercaptoacetic asidhi, nezvimwewo.

Iyo polycarboxylic acid yekudzikisa mvura mumiririri synthesis nzira ndeiyi: mufurasiki yepasi yakatenderedzwa ine electric stirrer, thermometer, chinodonhedza mudziyo, uye reflux condenser, iyo polymerization monomer solution uye initiator solution inowedzerwa zvishoma nezvishoma nenzira yekudziya mubhavhu remvura. Pakusarudza iyo polymerization monomer , Iyo yunivhesiti ine chiyero chemakwikwi inofanirwa kutariswa zvizere. Iyo tembiricha yekuita inogona kutsanangurwa zvichienderana neyakananga maitiro monomer mhando. Kazhinji, tembiricha mutembiricha ye70 ~ 95 ℃ inogona kusarudzwa seyekuita tembiricha.

Donhedza monomer solution mukati meawa imwe chete, wobva waidonhedza mukati memaminitsi makumi maviri wobva waisa yasara yekutangisa mhinduro, uye wozopedzisira wawedzera tembiricha ne5°C, enderera mberi nekuita kwe1h, uye kana tembiricha yadzikiswa kusvika pa40°C, gadzirisa uye discharge.
