Dab tsi ua rau Polyacrylamide zoo heev ntawm Flocculation?

Polyacrylamidetau lees paub dav dav rau nws txoj kev ua haujlwm zoo hauv kev ua kom cov dej ntws tawm, ib qho txheej txheem tseem ceeb hauv ntau yam lag luam xws li kev kho dej khib nyiab, kev khawb av, thiab kev ua ntawv. Cov polymer hluavtaws no, muaj cov acrylamide monomers, muaj cov yam ntxwv tshwj xeeb uas ua rau nws tsim nyog rau kev siv cov dej ntws tawm.

Ua ntej tshaj plaws, qhov hnyav molecular siab ntawm polyacrylamide yog qhov tseem ceeb uas ua rau nws muaj peev xwm ua kom zoo tshaj plaws. Cov saw ntev ntawm cov acrylamide rov ua dua tso cai rau kev sib cuam tshuam ntau nrog cov khoom me me hauv cov tshuaj. Cov qauv molecular no ua rau cov polymer muaj peev xwm tsim cov flocs loj thiab ruaj khov, uas yog cov khoom me me. Yog li ntawd, polyacrylamide tuaj yeem khi ua ke cov khoom me me, ua rau lawv sai sai lossis sib cais los ntawm cov kua.

Qhov xwm txheej uas polyacrylamide yaj tau hauv dej ua rau nws cov kev ua haujlwm flocculation zoo dua. Vim tias nws yaj tau hauv dej, polyacrylamide tuaj yeem yooj yim tawg thiab sib xyaw rau hauv cov tshuaj, ua kom muaj kev faib tawm sib npaug thoob plaws hauv lub cev. Cov yam ntxwv no yog qhov tseem ceeb rau kev ua tiav cov flocculation zoo thiab ruaj khov, vim tias cov polymer yuav tsum tau kov txhua yam khoom me me hauv cov tshuaj kom tsim cov flocs.

Qhov tsis muaj hluav taws xob ntawm Polyacrylamide yog lwm qhov tseem ceeb uas ua rau nws cov dej ua haujlwm tau zoo. Cov polymer feem ntau tsis yog ionic, uas txhais tau tias nws tsis muaj hluav taws xob. Qhov tsis muaj hluav taws xob no ua rau polyacrylamide cuam tshuam nrog ntau yam khoom me me, txawm tias lawv cov nqi ntawm qhov chaw. Qhov sib txawv, cov anionic lossis cationic polymers tej zaum yuav xaiv tau hauv lawv cov khoom ua kom dej ua haujlwm, txwv tsis pub siv rau cov khoom me me. Qhov tsis muaj hluav taws xob ntawm Polyacrylamide ua rau nws siv tau ntau yam thiab haum rau ntau yam kev kho dej.

Ntxiv mus, qhov kev tswj hwm hydrolysis ntawm polyacrylamide tuaj yeem ua rau muaj cov pab pawg anionic, ua rau nws cov kev ua haujlwm flocculation zoo dua. Los ntawm kev hloov kho cov yam ntxwv ntawm cov polymer, nws ua haujlwm tau zoo dua hauv kev nyiam thiab neutralizing cov khoom me me nrog cov nqi sib txawv. Qhov kev hloov pauv no hauv kev tswj hwm them nqi tso cai rau polyacrylamide hloov kho rau cov dej sib txawv thiab kho nws cov peev xwm flocculation raws li.

Qhov yooj ywm ntawm polyacrylamide nyob rau hauv cov nqe lus ntawm nws lub cev daim ntawv kuj pab txhawb rau nws cov txiaj ntsig hauv cov txheej txheem flocculation. Nws muaj nyob rau hauv ntau yam daim ntawv xws li emulsions, hmoov, thiab gels. Qhov kev sib txawv no ua rau cov neeg siv xaiv daim ntawv tsim nyog tshaj plaws raws li cov kev xav tau tshwj xeeb ntawm lawv daim ntawv thov. Piv txwv li, emulsions feem ntau nyiam rau kev yooj yim ntawm kev tuav, thaum hmoov muab kev yooj yim hauv kev khaws cia thiab kev thauj mus los.

Xaus lus, polyacrylamide qhov kev ua tau zoo tshaj plaws ntawm flocculation yog vim nws qhov hnyav molecular siab, solubility hauv dej, them neutrality, versatility hauv kev tswj hwm them, thiab kev ywj pheej hauv daim ntawv lub cev. Cov khoom no ua ke ua rau polyacrylamide ua cov polymer zoo heev thiab ntau yam hauv kev pab txhawb kev tsim cov flocs ruaj khov, yog li pab txhawb kev sib cais thiab tshem tawm cov khoom me me ntawm cov kua hauv ntau yam txheej txheem kev lag luam.
