Lub luag haujlwm Magical ntawm Polyacrylamide hauv Papermaking Field

Polyacrylamideyog ib lo lus dav dav rau homopolymers ntawm acrylamide lossis copolymer nrog lwm cov monomers. Nws yog ib qho ntawm feem ntau siv dej-soluble polymers. Polyacrylamide muaj nyob rau hauv daim ntawv ntawm dawb granules thiab muab faib ua plaub hom: non-ionic, anionic, cationic, thiab amphoteric ionic.

Kev siv ntawm Polyacrylamide hauv Papermaking Field

Cov txheej txheem papermaking muaj ntau theem, suav nrog pulping, tshuaj ntsuam, tu, refining, thiab sib sau. Thaum cov txheej txheem no, ntau yam impurities xws li fibers, fillers, thiab nplua raug tsim tawm. Yog tias cov impurities no tsis raug tshem tawm ntawm cov ntaub so ntswg, lawv tuaj yeem ua rau muaj teeb meem xws li cov dej tsis zoo thiab cov ntawv tsis muaj zog. Polyacrylamide feem ntau yog siv los ua dispersant, kev pab tuav pov hwm, dej pab, flocculant, thiab sizing tus neeg sawv cev hauv cov txheej txheem papermaking.

Ⅰ. Dispersant

Ntxiv cov polyacrylamide dispersant thaum lub sij hawm papermaking txheej txheem tuaj yeem tiv thaiv cov agglomeration ntawm fibers thiab txhim kho cov uniformity ntawm daim ntawv. Tus nqi qis ntxiv tuaj yeem txhawb nqa qhov zoo ntawm cov ntaub ntawv fiber ntau thiab ua tiav cov ntawv zoo heev. Nws tseem tuaj yeem txhim kho cov tawv nqaij sib xws thiab qhov muag ntawm daim ntawv, thiab txhim kho lub zog ntawm daim ntawv. Nws yog tsim rau ntau yam khoom siv hauv tsev xws li daim ntawv tso quav tso quav, cov ntaub so ntswg, cov ntaub so ntswg ntawm lub ntsej muag, thiab lwm yam ntaub ntawv nyias. Hauv qee cov ntawv zeb, nws tuaj yeem hloov pauv Polyethylene Oxide (PEO).

Ⅱ. Retention Aid

PAM feem ntau yog siv los ua ib qho kev pab khaws cia hauv kev lag luam papermaking kom nce cov fiber ntau tuav thiab txo cov dej phwj tuaj. Nws txoj hauv kev ua haujlwm yog tsim cov flocs loj nrog cov khoom me me, uas tuaj yeem yooj yim tshem tawm ntawm cov tawv nqaij los ntawm kev pom los yog sedimentation.

Ⅲ. Kev pab dej

PAM kuj tseem tuaj yeem pab ua kua dej hauv cov txheej txheem papermaking. Nws ua rau kom tus nqi ntws tawm, ua kom nrawm dua thiab ua kom muaj txiaj ntsig zoo ntawm cov ntawv ntawm cov ntawv tshuab. Qhov no yuav pab ua kom cov khoom lag luam nrawm thiab txo qis kev siv hluav taws xob los ntawm kev ua kom lub sij hawm ziab kom luv rau daim ntawv.

Ⅳ. Sizing Tus neeg saib xyuas

Qee zaum, polyacrylamide yog siv los ua tus neeg sawv cev sizing hauv papermaking los tswj kev nkag mus ntawm dej thiab lwm yam kua rau hauv daim ntawv. Qhov no yuav pab ua kom tiav cov khoom uas xav tau xws li dej tsis kam thiab number case tuav, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas yuav tsum tau tiv taus ya raws los yog luam ntawv txheej txheem.

Ⅴ. Flocculant

Thaum cov txheej txheem kho dej khib nyiab hauv cov ntawv zeb, polyacrylamide tuaj yeem siv los ua flocculant kom tshem tawm cov khib nyiab thiab cov pa phem hauv cov dej khib nyiab. Nws pab tsim cov khoom loj dua hu ua flocs, uas tuaj yeem yooj yim tshem tawm los ntawm cov txheej txheem sedimentation lossis pom. Qhov no pab txo qis dej paug thiab txhim kho ib puag ncig sustainability ntawm kev lag luam papermaking.

Zuag qhia tag nrho, ntau yam khoom ntawm polyacrylamide ua rau nws yog ib qho tseem ceeb ntxiv rau hauv kev lag luam papermaking, pab txhim kho kev ua tau zoo, cov khoom zoo, thiab kev ua haujlwm ntawm cov khoom ntawv. Daim ntawv thov ntawm polyacrylamide nyob rau hauv daim teb papermaking spans tag nrho papermaking kev lag luam saw, los ntawm daim ntawv ntau lawm mus rau cov dej khib nyiab. Nws tsis tsuas yog txhim kho qhov zoo thiab kev ua haujlwm ntawm cov ntawv, txo cov nqi tsim khoom, tab sis kuj ua rau muaj txiaj ntsig zoo rau kev tiv thaiv ib puag ncig.
