Ua ntej, cia peb saib ntawm cov chaw ntawm cov khoom siv ntawm cov ntawv los ntawm cov ntawv mills. Feem ntau ntawm cov ntaub ntawv los ntawm cov ntawv mills suav nrog cov khoom siv dej so rau cov ntaub ntawv nyoos, thiab cov dej ntxuav kom huv, thiab cov dej ntxuav kom huv ntawm cov ntawv sau ua kua thiab cov khoom siv dej ntxuav kom ntau. Tseem ceeb tshaj, cov impurities nyob rau hauv cov ntaub ntawv lim los ntawm cov ntawv mills yog qhov nyuaj thiab cov khoom siv nyuaj ntau dua ntawm kev lag luam pov tseg. Yog tias tawm ncaj qha yam tsis muaj kev kho mob, nws yuav ua rau muaj kuab paug loj rau cov dej tsis zoo ntawm ib puag ncig ib puag ncig. Ntxiv mus, kev siv cov ntawv lag luam mills feem ntau yog qhov loj me thiab ncaj qha yuav ua rau cov khib nyiab ntawm cov khoom siv dej. Peb polyacrylamide tuaj yeem ua rau qhov tsis huv hauv cov dej khib nyiab kom nrawm nrawm rau hauv cov flocs. Tom qab kev kho cov dej, dej tuaj yeem rov qab tuaj rau qhov pom tseeb. Yog li, cov dej uas ua tau raws li cov qauv kev coj tsis zoo yuav tsis ua rau cov pa phem ib puag ncig. Ntxiv mus, nws tuaj yeem ua tiav qee cov dej rov qab dej thiab kev txuag hluav taws xob.
Papermerming additive polyacrylamide
Ntawm chav kawm, polyacrylamide tsis tsuas yog muaj cov txiaj ntsig zoo hauv kev kho cov dej lim dej los ntawm cov ntawv sau ntxiv thiab ua si lub luag haujlwm zoo heev hauv cov txheej txheem papermakaking. Ntxiv ib qho me me ntawm polyacrylamide thaum lub sij hawm paperminaka tuaj yeem txhim kho tus nqi rawermaking, thiab tseem nce lub zog ntawm cov ntawv thiab txhim kho cov ntawv zoo. Yog li ntawd, polyacrylamide tseem siv tau siv raws li qhov papermaking additive. Ntxiv mus, cov dej dawb tsim los ntawm lub tshuab dawb papermaking feem ntau muaj cov ntsiab lus raw heev. Peb kuj tseem tuaj yeem siv cov txiaj ntsig flocculation ntawm polyacrylamide kom rov qab cov ntaub ntawv. Cov ntaub ntawv zoo noj tau tuaj yeem siv los ua cov khoom lag luam qib qis lossis rau lwm lub hom phiaj, uas tuaj yeem txuag cov peev txheej zoo dua.
Dab tsi yog tus nqi ntawm polyacrylamide ib tev rau cov ntawv nruab chaws?
Qhov tseeb, txawm siv los ua cov ntawv sau ua haujlwm pov thawj lossis cov papermaking ntxiv, daim ntawv thov cov nyhuv ntawm polyacrylamide yog qhov zoo heev. Tau kawg, qhov no tseem yuav tsum xaiv cov kev tshwj xeeb zoo ntawm polyacrylamide. Peb txhua tus paub tias polyacrylamides uas muaj xws li anionic polyacrylamide, cationic polyacrylamide thiab noionic polyacrylamide. Vim yog cov dej sib txawv ntawm cov dej phwj, cov specifications ntawm polyacrylamide siv kuj tseem txawv. Feem ntau, peb yuav sim cov dej phwj dej los txiav txim cov kev tshwj xeeb ntawm polyacrylamide siv. Cov nqi ntawm polyacrylamide ntawm cov sib txawv kuj sib txawv. Lub siab dua cov molecular hnyav thiab ion degree ntawm polyacrylamide, qhov siab dua nws tus nqi. Yog tias koj xav paub txog cov specifications thiab cov nqi ntawm polyacrylamide siv nyob rau hauv kom meej, koj tuaj yeem tiv tauj peb ncaj qha. Henan Saifu Cov ntaub ntawv tshiab yuav muab ntau cov ncauj lus kom ntxaws thiab txaus siab rau cov kev pabcuam.
