Polycarboxylate Superplasticizer PCEbụ nke mejupụtara macromolecular ogige na sulfonic acid otu, carboxyl otu, amino otu, na polyoxyethylene n'akụkụ agbụ ígwè, wdg, na aqueous ngwọta, site ụkpụrụ nke free radical copolymerization njikọ nke polymers na a comb Ọdịdị Surfactant.

Isi akụrụngwa chọrọ maka njikọ nkeIhe nrụpụta mmiri ọgwụ Polycarboxylate Superplasticierbụ: 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. The niile e ji e mee ihe. na polymerization usoro bụ: persulfate dabeere initiators, Benzoyl peroxide, azobisisobutyl cyanide; Ndị na-enyefe ndị na-ebugharị yinye: 3-mercaptopropionic acid, mercaptoacetic acid, wdg.

Ihe na-ebelata mmiri nke polycarboxylic acid Usoro njikọ bụ: n'ime flask dị gburugburu nke nwere ihe ọkụ eletrik, ihe ọkụ ọkụ, ngwaọrụ nkwụsịtụ, na reflux condenser, polymerization monomer solution na ngwọta initiator na-eji nwayọọ nwayọọ na-agbakwụnye dropwise site na usoro ikpo ọkụ na mmiri ịsa ahụ. Mgbe ị na-ahọrọ monomer polymerization, mahadum nwere ọnụego asọmpi ya kwesịrị ịtụle nke ọma. Enwere ike ikpebi okpomọkụ mmeghachi omume dịka ụdị mmeghachi omume monomer kpọmkwem.
