Acrylamide kupanga ndondomeko ndi mfundo

Njira yopangira

Njira 1: Njira ya Hydrolysis
Theacrylamideakamagwira hydrolysis njira ali kusasamba kugawa unyolo acrylamide pa unyolo macromolecular.Molar peresenti yaacrylamideunyolo pa unyolo macromolecular ndi digiri ya hydrolysis.
Poyerekeza ndi njira ya copolymerization, madzi osungunuka odana ndi dandruff factor (HD) azinthu zokonzedwa ndi njira ya hydrolysis sipamwamba, zosakwana 30%.Theoretically, mankhwala ndi HD oposa 70% ayenera kukonzekera ndi njira copolymerization, amene ali zofunika zina pa kutentha hydrolysis ndi zochitika, ndipo sachedwa kuwonongeka macromolecular pa ndondomeko hydrolysis.

Njira 2: Polymerization yamadzimadzi
Amadzimadzi njira polymerization polymerization zimene monoma anachita ndi initiator ndi kusungunuka m'madzi.Njira imeneyi ndi yosavuta, zochepa kuipitsa chilengedwe, mkulu zokolola za polima, zosavuta kupeza mkulu wachibale maselo kulemera polima, ndi njira yoyamba ntchito mu kupanga mafakitale polyacrylamide, ndipo wakhala njira yaikulu ya mafakitale kupanga polyacrylamide.The polymerization wa amadzimadzi njira wakhala anaphunzira mozama.

Njira 3: Inverted emulsion polymerization
Osintha gawo colloidal kupezeka dongosolo ayenera kukonzekera pamaso n'zosiyana-gawo emulsion polymerization ndi n'zosiyana-gawo kuyimitsidwa polymerization, ndiko kuti, madzi/mafuta (W/0) sakanikira kubalalitsidwa dongosolo aumbike mu mafuta gawo la monoma amadzimadzi njira ndi oyambitsa kubalalitsidwa. kapena emulsifier, ndiyeno woyambitsa amawonjezedwa kuti apange polymerization yaulere.
Nthawi zambiri, zoyambira zosungunuka zamafuta zimagwiritsidwa ntchito mu reversed-phase emulsion polymerization, makamaka anionic free radical Initiators ndi non-ionic free radical initiators, pomwe kuyimitsidwa kwa gawo loyimitsidwa kumagwiritsa ntchito zoyambira zosungunuka m'madzi, monga persulfate.Pali malingaliro awiri pa nucleation limagwirira wa AM/AA reversed emulsion polymerization: micellar nucleation ndi monomer droplet nucleation.The kinetics ndi yosiyana kwambiri ndi mmene zabwino emulsion polymerization.

Njira 4: Reverse kuyimitsidwa polymerization
Reversed-gawo kuyimitsidwa polymerization ndi njira yabwino kwa mafakitale kupanga ma polima sungunuka madzi opangidwa zaka 10 zaposachedwa.Di-monie anaphunzira AM reversed-phase kuyimitsidwa polymerization pogwiritsa ntchito conductivity, NMR ndi electron microscopy mu 1982.

Njira 5: Njira zina zama polymerization
Kuwonjezera pamwamba njira, ndi homopolymer ndi copolymer wa acrylamide ndi zotumphukira zake akhoza kusinthidwa ndi Mannich anachita ndi Ankalumikiza copolymerization.The kumayambiriro amines mu Polyacrylamide pa Mannich anachita ndi njira yofunika kupeza cationic polyelectrografting wa Polyacrylamide.Amines omwe amagwiritsidwa ntchito kwambiri ndi dimethylamine, diethylamine, diethanolamine ndi zina zotero.

AM/AA nthawi zambiri amamezetsanidwa ndi wowuma kuti apange utomoni woyamwa kwambiri, kapena ndi ma macromolecular monomers kuti alumikiza AM/AA mu nembanemba zina.High molecular kulemera cationic polyacrylamide (CPAM) chimagwiritsidwa ntchito kupanga mafuta, koma HPAM ali osauka kulolerana mchere.
