Polycarboxylate Superplasticizer PCEe entsoe ka metsoako ea macromolecular e nang le lihlopha tsa sulfonic acid, lihlopha tsa carboxyl, lihlopha tsa amino, le liketane tsa mahlakoreng a polyoxyethylene, joalo-joalo, ka tharollo e nang le metsi, ka molao-motheo oa ho kopanya li-radical copolymerization tsa mahala tse nang le sebopeho sa comb Surfactant.

Thepa e ka sehloohong e tala e hlokehang bakeng sa synthesis eaLik'hemik'hale tsa kaho Metsi a fokotsang metsi Polycarboxylate Superplasticierke: 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, joalo-joalo e ka sebelisa beyl initiate, joalo-joalo. ts'ebetsong ea polymerization ke: li-initiators tse thehiloeng ho persulfate , Benzoyl peroxide, azobisisobutyl cyanide; 3-mercaptopropionic acid, mercaptoacetic acid, joalo-joalo.

Polycarboxylic acid e fokotsang metsi mokhoa oa ho kopanya ke: ka botlolong e chitja e tlase e nang le mochini o futhumatsang motlakase, thermometer, sesebelisoa sa ho theola, le condenser ea reflux, tharollo ea polymerization monomer le tharollo ea initiator li kenngoa butle butle ka mokhoa oa ho futhumatsa ka bateng ea metsi. Ha u khetha polymerization monomer , Univesithi e nang le sekhahla sa tlholisano ea eona e lokela ho nahanoa ka botlalo. Mocheso oa karabelo o ka khethoa ho latela mofuta o itseng oa karabelo ea monomer. Ka kakaretso, mocheso oa mocheso oa 70 ~ 95 ℃ o ka khethoa e le mocheso oa karabelo.

Lahlela tharollo ea monomer nakong ea hora e le 'ngoe, ebe u e theola ka mor'a metsotso e 20 eketsa tharollo e setseng ea initiator,' me qetellong eketsa mocheso ka 5 ° C, tsoela pele ho itšoara ka 1h, 'me ka mor'a hore mocheso o theohe ho 40 ° C, fokotsa le ho fokotsa mocheso. phallela.
