Mokhoa oa tlhahiso
Mokhoa oa 1: Mokhoa oa Hydrolysis
Theacrylamidefumanoa ka hydrolysis mokhoa o na le kabo e sa tloaelehang ea liketane acrylamide ka liketane macromolecular.Peresente ea molar eaacrylamideliketane ka liketane tsa macromolecular ke tekanyo ea hydrolysis.
Ha ho bapisoa le mokhoa oa copolymerization, "anti-dandruff factor" (HD) e qhibilihang ka metsi ea lihlahisoa tse lokiselitsoeng ke mokhoa o tloaelehileng oa hydrolysis ha o phahame, o ka tlase ho 30%.Ka khopolo, lihlahisoa tse nang le HD ho feta 70% li lokela ho lokisoa ke mokhoa oa copolymerization, o nang le litlhoko tse itseng ka mocheso oa hydrolysis le liketsahalo, 'me o na le tšekamelo ea ho senyeha ha macromolecular nakong ea ts'ebetso ea hydrolysis.
Mokhoa oa 2: Polymerization ea tharollo ea metsi
Aqueous solution polymerization polymerization eo ho eona karabelo monomer le initiator ba qhibiliha ka metsing.Mokhoa ona o bonolo, o tlase tšilafalo ea tikoloho, lihlahisoa tse phahameng tsa polymer, ho le bonolo ho fumana polymer e phahameng e amanang le limolek'hule, ke mokhoa oa pele o sebelisoang tlhahiso ea indasteri ea polyacrylamide, 'me e bile mokhoa o ka sehloohong oa tlhahiso ea indasteri ea polyacrylamide.Polymerization ea tharollo ea metsi e ithutoe ka botebo.
Mokhoa oa 3: Emulsion polymerization e kentsoeng
Reversed-phase colloidal dispersion system e hloka ho lokisoa pele ho reversed-phase emulsion polymerization le reversed-phase suspension polymerization, ke hore, metsi/oli (W/0) heterogeneous disspersion system is the phase of oil monomer aqueous solution ka ho susumetsa ho hasana. kapa emulsifier, ebe ho kenyelletsoa initiator bakeng sa polymerization ea mahala.
Ka kakaretso, li-initiators tse qhibilihang ka oli li sebelisoa ho reverse-phase emulsion polymerization, haholo-holo li-anionic free radical Initiators le li-non-ionic free radical Initiators, ha polymerization ea reverse-phase e sebelisa lisebelisoa tse qhibilihang ka metsing, tse kang persulfate.Ho na le maikutlo a mabeli mabapi le mochine oa nucleation oa AM / AA reversed emulsion polymerization: micellar nucleation le monomer droplet nucleation.The kinetics e fapane haholo le e tloaelehileng ea emulsion polymerization.
Mokhoa oa 4: Fetola polymerization ea ho emisa
Reversed-phase suspension polymerization ke mokhoa o nepahetseng bakeng sa tlhahiso ea indasteri ea li-polymers tse qhibilihang ka metsi tse ntlafalitsoeng lilemong tsa morao tjena tse 10.Di-monie o ithutile AM reversed-phase suspension polymerization a sebelisa conductivity, NMR le electron microscopy ka 1982.
Mokhoa oa 5: Mekhoa e meng ea polymerization
Ho phaella ho mekhoa e ka holimo, homopolymer le copolymer ea acrylamide le lihlahisoa tsa eona li ka fetoloa ka mokhoa oa Mannich le copolymerization ea grafting.Ho kenyelletsoa ha li-amine ka polyacrylamide nakong ea Mannich karabelo ke tsela ea bohlokoa ea ho fumana cationic polyelectrografting ea polyacrylamide.Li-amine tse sebelisoang hangata ke dimethylamine, diethylamine, diethanolamine joalo-joalo.
Hangata AM/AA e hlomathiseletsoa ka starch ho lokisa lirese tse monyang haholo, kapa ka li-monomer tse ling tsa macromolecular ho hlomathisetsa AM/AA ka har'a lera le itseng.High molecular weight cationic polyacrylamide (CPAM) e sebelisoa haholo tlhahisong ea oli, empa HPAM e na le mamello e fokolang ea letsoai.
