Habka wax soo saarka acrylamide iyo mabda'a

Habka wax soo saarka

Habka 1: Habka Hydrolysis
Theacrylamidelagu helay habka hydrolysis waxay leedahay qaybinta aan joogtada ahayn ee silsiladaha acrylamide ee silsiladaha makromolecular. Boqolkiiba molar eeacrylamidesilsiladaha silsiladaha makromolecular waa heerka hydrolysis.
Marka la barbar dhigo habka copolymerization, factor anti-druff factor (HD) ee biyaha ku milma ee alaabta lagu diyaariyey habka biyo-ilaalinta guud maaha mid sarreeya, wax ka yar 30%. Aragti ahaan, alaabooyinka leh HD in ka badan 70% waa in lagu diyaariyaa habka copolymerization, kaas oo leh shuruudo gaar ah oo ku saabsan heerkulka hydrolysis iyo dhacdooyinka, oo u nugul nabaad-guurka macromolecular inta lagu jiro habka biyo-saarka.

Habka 2: Polymerization of xal aqueous
Polymerization Xalka Aqueous kaas oo monomer falcelinta iyo bilawga lagu milmo biyaha. Habkani waa mid sahlan, wasakhda deegaanka yar, wax-soo-saarka sare ee polymer, si sahlan loo heli karo culeyska culeyska molecular ee sarreeya, waa habka ugu horreeya ee loo isticmaalo soosaarka warshadaha ee polyacrylamide, wuxuuna ahaa habka ugu muhiimsan ee wax soo saarka warshadaha ee polyacrylamide. polymerization of xal aqueous ayaa si qoto dheer loo bartay.

Habka 3: polymerization emulsion rogan
Nidaamka kala firdhiso colloidal weji-rogid wuxuu u baahan yahay in la diyaariyo ka hor intaysan noqon polymerization emulsion weji iyo celin-polymerization hakinta, taas oo ah, biyaha / saliidda (W / 0) nidaamka kala firidhsan kala duwan ayaa lagu sameeyay wajiga saliidda monomer xal aqueous by walaaqaya kala firdhiso ama emulsifier, ka dibna bilawga ayaa lagu daraa polymerization saldhig bilaash ah.
Guud ahaan, bilawyeyaasha dareeraha milmay ee saliidda waxa loo isticmaalaa polymerization emulsion wejiga-rogista, badiyaa hindiseyaasha xagjirka xorta ah ee anionic iyo kuwa bilaa-ionic bilaabay xagjirka xorta ah, halka polymerization-ka-noqoshada-la-soo-noqoshada loo isticmaalo hindiseyaasha biyaha milmaya, sida persulfate. Waxaa jira laba aragtiyood oo ku saabsan habka nukliyeerka ee AM/AA dib-u-celinta emulsion polymerization: nucleation micellar iyo monomer droplet nucleation. Kinetics-ku aad ayuu uga duwan yahay kan emulsion-ka caadiga ah ee polymerization.

Habka 4: Dib-u-noqoshada polymerization hakinta
polymerization-ka-joojinta joojinta wejiga waa habka ugu habboon ee wax soo saarka warshadaha ee polymers-ka biyaha-milmi kara ee la sameeyay 10kii sano ee la soo dhaafay. Di-monie waxa uu bartay polymerization-ka-joojinta wejiga-joojinta iyadoo la adeegsanayo kororka, NMR iyo microscopy elektarooniga ah 1982.

Habka 5: Hababka kale ee polymerization
Marka lagu daro hababka kor ku xusan, homopolymer-ka iyo copolymer ee acrylamide iyo ka-soo-saareheeda waxa wax ka beddeli kara falcelinta Mannich iyo isku-duubnida tallaalka. Soo bandhigida amines ee polyacrylamide inta lagu guda jiro falcelinta Mannich waa hab muhiim ah oo lagu helo polyacrylamide cationic polyacrylamide. Amines-ka inta badan la isticmaalo waa dimethylamine, diethylamine, diethanolamine iyo wixii la mid ah.

AM/AA waxaa inta badan lagu tallaalaa istaarijka si loogu diyaariyo resins aadka u nuugaya, ama monomers kale oo makromolecular ah si AM/AA loogu tallaalo xuubabka qaarkood. Miisaanka molecular sare ee cationic polyacrylamide (CPAM) ayaa si weyn loogu isticmaalaa soosaarka saliidda, laakiin HPAM waxay leedahay dulqaad milixeed liidata.
