Keʻano 1: Keʻano hydrolysis
ʻO kaacrylamideLoaʻa i ke ʻano hydrolysis ka hāʻawi ʻole ʻia o nā kaulahao acrylamide ma nā kaulahao macromolecular.ʻO ka pākēneka molar oacrylamideʻO nā kaulahao ma nā kaulahao macromolecular ka degere o ka hydrolysis.
Ke hoʻohālikelike ʻia me ke ʻano copolymerization, ʻaʻole kiʻekiʻe ka wai-soluble anti-dandruff factor (HD) o nā huahana i hoʻomākaukau ʻia e ke ʻano hydrolysis maʻamau, ma lalo o 30%.ʻO ka manaʻo, pono e hoʻomākaukau ʻia nā huahana me ka HD ma mua o 70% e ke ʻano copolymerization, aia kekahi mau koi e pili ana i ka mahana hydrolysis a me nā hanana, a hiki ke hoʻohaʻahaʻa i ka macromolecular degradation i ka wā o ke kaʻina hydrolysis.
Ka Papa Hana 2: Polymerization o ka hoʻonā wai
ʻO ka polymerization polymerization solution kahi e hoʻoheheʻe ʻia ai ka monomer reaction a me ka mea hoʻomaka i ka wai.He maʻalahi kēia ʻano, liʻiliʻi ka pollution kaiapuni, kiʻekiʻe kiʻekiʻe o ka polymer, maʻalahi e kiʻi i ke kiʻekiʻe o ka molecular weight polymer, ʻo ia ke ʻano mua i hoʻohana ʻia i ka hana ʻenehana o polyacrylamide, a ʻo ia ke ʻano nui o ka hana ʻana o ka polyacrylamide.Ua aʻo hohonu ʻia ka polymerization o ka hoʻonā wai.
Ka Papa Hana 3: Hoʻohuli ʻia ka emulsion polymerization
Pono e hoʻomākaukau ʻia ka ʻōnaehana hoʻopuehu colloidal i hoʻohuli ʻia ma mua o ka polymerization emulsion reversed-phase a me ka polymerization hoʻokuʻu ʻia, ʻo ia hoʻi, ka wai/ʻaila (W/0) heterogeneous dispersion system i hoʻokumu ʻia i ka ʻaila ʻaila o ka monomer aqueous solution ma ka hoʻoulu ʻana i ka hoʻopuehu. a i ʻole emulsifier, a laila hoʻohui ʻia ka mea hoʻomaka no ka polymerization kumu manuahi.
ʻO ka maʻamau, hoʻohana ʻia nā mea hoʻomaka ʻaila i loko o ka polymerization emulsion reversed-phase, ka hapa nui o nā mea hoʻomaka radical manuahi anionic a me nā mea hoʻomaka radical manuahi ʻole, ʻoiai hoʻohana ʻia ka polymerization hoʻokuʻu ʻia i ka wai, e like me ka persulfate.ʻElua mau manaʻo e pili ana i ka hana nucleation o AM/AA i hoʻohuli ʻia emulsion polymerization: micellar nucleation a me ka monomer droplet nucleation.ʻOkoʻa loa nā kinetics mai ka polymerization emulsion maikaʻi maʻamau.
Kaʻina 4: Hoʻohuli i ka polymerization hoʻomaha
ʻO ka polymerization hoʻokuʻu ʻia i ka manawa he ala kūpono no ka hana ʻana i nā polymers wai-soluble i kūkulu ʻia i nā makahiki he 10 i hala iho nei.Ua aʻo ʻo Di-monie i ka polymerization hoʻokuʻu ʻana i ka manawa hoʻohuli i ka hoʻohana ʻana i ka conductivity, NMR a me ka microscopy electron ma 1982.
Ka Papa Hana 5: Nā ʻano hana polymerization ʻē aʻe
Ma waho aʻe o nā ʻano o luna, hiki ke hoʻololi ʻia ka homopolymer a me ka copolymer o ka acrylamide a me kāna mau derivatives e ka hopena Mannich a me ka grafting copolymerization.ʻO ka hoʻokomo ʻana o nā amine i loko o ka polyacrylamide i ka wā o ka hopena Mannich he ala koʻikoʻi ia e loaʻa ai ka cationic polyelectrografting o polyacrylamide.ʻO nā amine i hoʻohana pinepine ʻia ʻo dimethylamine, diethylamine, diethanolamine a pēlā aku.
Hoʻopili pinepine ʻia ʻo AM/AA me ka starch no ka hoʻomākaukau ʻana i nā resins ʻoluʻolu loa, a i ʻole me nā monomers macromolecular ʻē aʻe e kālai i ka AM/AA i kekahi mau membrane.Hoʻohana nui ʻia ka polyacrylamide cationic molecular kiʻekiʻe (CPAM) i ka hana ʻaila, akā maikaʻi ʻole ka HPAM i ka paʻakai.
