Polycarboxylate Superplasticizer PCEua haku ʻia me nā pūhui macromolecular me nā pūʻulu ʻakika sulfonic, pūʻulu carboxyl, pūʻulu amino, a me nā kaulahao ʻaoʻao polyoxyethylene, a me nā mea ʻē aʻe, i loko o ka hoʻonā wai, ma o ke kumu o ka synthesis copolymerization radical manuahi o nā polymers me kahi hui hui Surfactant.

ʻO nā mea maka nui e pono ai no ka synthesis oMea hoʻoemi wai ʻo Polycarboxylate Superplasticierʻo ia: 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, e hiki ke hoʻohana i nā allyl ether, etc. i loko o ke kaʻina hana polymerization: persulfate-based initiators , Benzoyl peroxide, azobisisobutyl cyanide;nā mea hoʻololi kaulahao: 3-mercaptopropionic acid, mercaptoacetic acid, etc.

ʻO ka polycarboxylic acid ka mea hoʻemi wai ʻO ke ʻano o ka synthesis: i loko o kahi pahu pōʻai lalo i hoʻolako ʻia me kahi mea hoʻoheheʻe uila, kahi thermometer, kahi mea hoʻoheheʻe, a me kahi condenser reflux, hoʻohui lohi ʻia ka polymerization monomer solution a me ka hopena hoʻomaka ma ke ʻano o ka hoʻomehana ʻana i ka ʻauʻau wai.Ke koho ʻana i ka monomer polymerization , Pono e noʻonoʻo pono ʻia ke kulanui me kāna helu hoʻokūkū.Hiki ke hoʻoholo ʻia ka mahana hopena e like me ke ʻano monomer reaction.ʻO ka maʻamau, hiki ke koho ʻia ka mahana ma ka pae wela o 70 ~ 95 ℃ e like me ke ʻano wela.

E hoʻokuʻu i ka solution monomer i loko o hoʻokahi hola, a laila e hoʻokuʻu i loko o 20 mau minuke e hoʻohui i ke koena mea hoʻomaka, a ma hope e hoʻonui i ka mahana ma 5 ° C, e hoʻomau i ka pane no 1h, a ma hope o ka hoʻohaʻahaʻa ʻana i ka mahana i 40 ° C, neutralize a hoʻokuʻu.
