Polyacrylamide rau Papermaking
Polyacrylamide yog ib hom linear polymer compound, uas yog ib lo lus dav dav rau linear water-soluble molecular chemicals uas tsim los ntawm homopolymerization los yog copolymerization ntawm acrylamide nrog lwm cov monomers. Nws kuj yog ib qho ntawm feem ntau siv ntau hom dej-soluble polymer tebchaw, nrog dej solubility zoo. Muaj feem ntauCationic Polyacrylamide (CPAM), Anionic Polyacrylamide (APAM), Non-ionic Polyacrylamide (NPAM), thiabAmphoteric Polyacrylamide.
Daim ntawv thov ntawm polyacrylamide hauv kev lag luam papermaking yog qhov dav heev, uas tuaj yeem hais tau los ntawm tag nrho cov txheej txheem papermaking.
1. Ntawv Dispersant
Anionic polyacrylamide yog siv los ua ib qho dispersant hauv papermaking, uas tuaj yeem txhawb kev tawg paj zoo ntawm papermaking fibers thiab zoo heev daim ntawv ua cov nyhuv ntawm tsawg npaum li cas, txhim kho pulp evenness thiab softness, thiab kuj nce lub zog ntawm daim ntawv. Nyob rau hauv daim ntawv thov txheej txheej, daim ntawv-ua dispersant muaj siab dispersion efficiency, ruaj khov xim viscosity, tsawg ua npuas ncauj, tsis muaj tshuaj lom, tsis corrosive, tuaj yeem txhim kho cov ntsiab lus ntawm cov xim, thiab muaj qhov zoo fluidity thiab txhuam tsis kam, tuaj yeem tuav cov ntawv ci, thiab tsis yooj yim los ua pwm. Daim ntawv dispersants kuj tuaj yeem ua rau kom ceev ntawm papermaking, txuag lub sijhawm ntaus, txo kev siv zog, thiab muaj txiaj ntsig kev lag luam tseem ceeb.
2. Paper Filter Aid
Cationic polyacrylamide yog siv nyob rau hauv cov txheej txheem khaws cia ntawm papermaking los siv cov nqi tsis zoo rau ntawm qhov chaw ntawm cov fillers, cationic polymer polyelectrolytes yog siv los cationic nws, ua rau kom cov adsorption ntawm filler hais nrog pulp fibers thiab zoo fibers, yog li txhim kho ib txoj kev tuav. tus nqi ntawm cov fillers, txo cov ntsiab lus muab tub lim hauv dej dawb, txo qhov poob, thiab txo cov nqi. Nws tseem tuaj yeem txo cov concentration thiab cov hmoov tshauv ntawm cov ntaub so ntswg ntawm cov hlau, thiab txuas ntxiv lub neej ntawm cov mesh tsim thiab cov smoothness thiab opacity ntawm daim ntawv tuaj yeem txhim kho.
3. Daim Ntawv Siv Tshuaj Kho Dej
Polyacrylamide kuj tseem tuaj yeem siv rau kev kho cov dej khib nyiab thiab cov fiber ntau rov qab, uas yog qhov tsim nyog rau kev ua raws li cov qauv tso tawm. Anionic polyacrylamide yog siv rau huab cua flotation thiab sedimentation, thaum cationic polyacrylamide yog siv rau cov av nkos.
Lvyuan Water Treatment muab ntau hom polyacrylamide, suav nrog anionic Powder, Cationic Powder, Non-ionic Powder, thiab Anionic Emulsion.
