Yuav ua li cas polydadmac (poly diallylaslammonium chloride)

Vim li cas thiaj xaiv polydadmac?

Raws li Tuam Tshoj lub papermaking tau ntev tau ua los ntawm graminaceous cog fiber, nrog cov ntsiab lus cog qoob loo, cov nplais nyom thiab cov txheej txheem dej tsis zoo hauv cov txheej txheem papermakaking.

Polydadmac tuaj yeem txhim kho qhov teeb meem ntawm cov dej qis thiab cov dej tsis zoo siv, txo tus nqi ntawm tons ntawm paps thiab ib puag ncig cov pa paug. Polydadmac kuj tseem tuaj yeem txhim kho cov dej lim pom kev ua haujlwm ntawm pulp thiab tsim ntawm daim ntawv ntawv.

Cov ntawv no tshawb xyuas cov adsorption, khaws cia, thiab kev ua kom pom tseeb ntawm polydadmac nrog cov khoom sib xyaw sib txawv ntawm cov tshuaj sib ntxiv ntawm cov neeg siv tshuaj ntsuab, thiab tau txais lub xaus rau hauv qab no.

1.Adalsorption ntawm Polydadmac ntawm Reed Pulp

Qhov hnyav me me ntawm polydadmac, qhov ntau dua qhov txo qis nrog qhov ua kom hnyav dua ntawm polydadmac, muaj peev xwm loj dua mus ntes Anions. Yuav tsum muaj cov polydadmac tsawg dua rau tib tus nqi ntawm anion hauv cov txheej txheem noo noo.

2.filetering nyhuv ntawm polydadmac

Nrog rau qhov nce zuj zus ntawm PolyDadmac, qhov kev ua raws li qhov kev txo qis thiab tseem tshaj li qhov uas muaj qhov ntxiv thaum nce mus txog thiab 0.8%. Qhov no txhais tau tias ntau Polydadmac tsis tau pab lim dej, tab sis ua kom pom cov dej lim ntawm pulp. Qhov ntawd txhais tau tias ntau qhov sib txawv molecular hnyav polydadmac tau siv cov nyhuv zoo dua ua ntej lawv saturated tus nqi tsis zoo ntawm lub pulp fiber ntau.

3. Cov kev cuam tshuam zoo ntawm Polydadmac

Raws li cov tshuaj ntau ntawm Polydadmac nce, cov khoom noj dawb ntawm cov kiv tshiab ntawm cov neeg siv roj ntsha tau txo ua ntej, thiab tom qab ntawd nce ntxiv. Qhov kev tshawb nrhiav no qhia tau tias ntxiv Polydadmac kom tau txhim kho cov nplua nuj thiab cov khoom siv ua kom zoo nkauj thiab txo cov khoom siv ua kom dej. Nws tau pom tias qhov kev ua tau zoo ntawm polydadmac tsis cuam tshuam los ntawm lawv cov kev hnyav; Tus me dua cov molecular qhov hnyav ntawm polydadmac, qhov zoo dua rau cov nyhuv rov ua dua tshiab. Tab sis qhov sib txawv tsis pom tseeb, thiab sib txawv molecular hnyav polydadmac muaj cov txiaj ntsig zoo dua nyob rau ntawm cov nqi tsis zoo ua ntej cov nqi tsis zoo tshwm sim.

Xaus:

1.Polydadmac nrog hnyav molecular hnyav muaj qhov pom zoo zoo thiab ua kom muaj kev cuam tshuam ntawm cov tshuaj pleev ib ce;
2. Txheeb xyuas cov txiaj ntsig zoo dua thiab rov ua kom zoo ua ntej thaum tus nqi polydadmac siv yog tsawg dua tus nqi tsis zoo nyob rau saum npoo ntawm pulp fibers;

3.Lawv lub cev yuag polydadmac Hamgood khaws cov nyhuv. Txawm li cas los xij, tsis muaj qhov sib txawv ntawm nws cov hauj lwm zoo hauv kev pabcuam kom pom kev thiab khaws cia.
