Yuav ua li cas thov polyacrylamide hauv cov ntawv zeb thiab nws ua haujlwm li cas?

Polyacrylamide yog cov khoom siv zoo tshaj plaws uas siv dav hauv kev lag luam ntawv.Nws muaj ntau yam tshwj xeeb thiab kev ua haujlwm, uas tuaj yeem txhim kho kev tsim khoom thiab cov khoom zoo ntawm cov ntawv mills.

Firstly, PAM tuaj yeem siv rau kev ua cov pulp.Nws tuaj yeem siv ua daim ntawv homogenizer, txhim kho, dispersant, lim pab thiab lwm yam.Nws txoj haujlwm yog txhawm rau txhim kho cov ntawv zoo sib xws, ua kom zoo dua cov ntawv zoo thiab lub zog, nce tus nqi khaws cia ntawm cov fillers thiab cov fibers zoo, txo qhov poob ntawm cov ntaub ntawv raw, txhim kho pom thiab rov ua haujlwm zoo, thiab txo cov pa phem ib puag ncig.Nyob rau hauv cov txheej txheem ntawm cov khoom siv pulp, cellulose thiab lwm yam impurities yuav sib tov ua ke, uas yuav cuam tshuam rau cov ntawv zoo.Kev siv PAM tuaj yeem cais cov impurities thiab txhim kho cov ntawv zoo.Tsis tas li ntawd, PAM tuaj yeem ua kom cov viscosity ntawm cov ntaub so ntswg, ua rau daim ntawv muaj zog dua.

STsis tas li ntawd, PAM kuj tseem siv tau rau kev ua dej huv.Hauv kev tsim cov ntawv, cov dej ntau yog siv los ntxuav thiab yaug cov ntawv.Cov dej khib nyiab no muaj ntau cov organic teeb meem thiab impurities.Yog tias tso tawm ncaj qha rau hauv ib puag ncig yam tsis muaj kev kho mob, nws yuav ua rau muaj kev puas tsuaj loj rau thaj chaw ib puag ncig ecological.Kev siv PAM tuaj yeem cais cov organic tebchaw thiab impurities, yog li ua kom dej huv.Tsis tas li ntawd, PAM tseem tuaj yeem pab tshem tawm cov khoom raug tshem tawm thiab cov tshuaj colloidal los ntawm dej, ua kom pom tseeb thiab pob tshab.

In cov ntsiab lus, PAM ua lub luag haujlwm tseem ceeb hauv cov ntawv zeb.Los ntawm kev siv PAM, cov ntawv zoo tuaj yeem txhim kho, pov tseg hauv cov txheej txheem tsim khoom tuaj yeem txo qis, cov dej khib nyiab tuaj yeem ua kom huv, thiab qhov chaw nyob ib puag ncig tuaj yeem tiv thaiv.Yog li ntawd, nyob rau yav tom ntej daim ntawv ua ntau lawm, PAM yuav txuas ntxiv ua lub luag haujlwm tseem ceeb.
