Ib "Riam Phom Khawv Koob" rau Kev Kho Dej Phwj: PolyDADMAC

Hauv kev tsim khoom lag luam thiab lub neej txhua hnub, qhov teeb meem ntawm cov dej phwj tuaj yeem hnyav zuj zus. PolyDADMAC siv dav rau kev ntxuav cov dej khib nyiab lag luam thiab dej saum npoo av. Nws yog siv rau kev kho cov dej khib nyiab los ntawm kev ua cov ntxhia, cov dej khib nyiab ua ntawv, cov dej khib nyiab roj los ntawm cov chaw roj thiab cov chaw ua roj, nrog rau cov dej khib nyiab hauv nroog. PolyDADMAC kuj tseem siv tau ua ib qhoflocculant rau kev kho dej kais.

PolyDADMAC yog dab tsi?

PolyDADMACyog ib qho cationic polymer, thiab nws cov tsos yog ib qho kua tsis muaj xim rau daj ntseg daj. Nws cov qauv molecular tshwj xeeb muab rau nws nrog cov khoom muaj zog flocculation thiab adsorption, ua rau nws sai sai sib xyaw nrog cov khoom me me uas raug tshem tawm, colloids thiab lwm yam khoom hauv dej.

Kev Kho Dej Khib Nyhiab

PolyDADMAC siv rau hauv kev kho dej khib nyiab ua cov tshuaj coagulant organic tseem ceeb uas ua rau cov khoom siv colloidal tsis zoo thiab txo cov sludge piv rau cov inorganic coagulants. PolyDADMAC siv ua cov tshuaj coagulant hauv kev ntxuav dej. Nws muaj txiaj ntsig zoo hauv kev coagulating thiab flocculating inorganic thiab organic particles xws li silt, av nplaum, algae, kab mob thiab kab mob. Ntawm cov concentration siab, cov organic polymer tuaj yeem tshem tawm cov organic matter xws li humic thiab fulvic acids ua rau muaj tsawg dua cov khoom siv tua kab mob thiab tsawg dua xim.

Kev Kho Dej Phwj Tuaj

Hauv kev kho dej phwj tuaj, PolyDADMAC ua tau zoo heev. Hauv kev kho cov dej khib nyiab ua ntawv, nws tuaj yeem ua kom cov tshuaj uas raug tshem tawm xws li cov fibers thiab cov khoom sau, ua rau cov dej khib nyiab sai sai. Thaum kho cov dej khib nyiab luam ntawv thiab zas xim, nws tuaj yeem sib xyaw nrog cov xim zas, rhuav tshem lawv cov chromophores, thiab tshem tawm cov xim zoo, yog li ua kom yooj yim rau kev kho cov dej khib nyiab luam ntawv thiab zas xim. Ntxiv mus, piv nrog cov flocculants ib txwm muaj, nws xav tau cov tshuaj me dua tab sis ua tiav cov txiaj ntsig zoo dua, uas tuaj yeem txo cov nqi kho mob.

Kev Tshawb Fawb Roj

Ntxiv rau kev kho dej phwj tuaj, hauv kev rho roj, nws tuaj yeem siv ua cov khoom ntxiv rau cov kua dej drilling kom txhim kho kev ruaj khov ntawm cov kua dej drilling thiab lawv lub peev xwm los nqa xuab zeb, kom ntseeg tau tias kev nce qib ntawm kev rho tawm du.

Kev Lag Luam Ntawv

Hauv kev lag luam ua ntawv, nws tuaj yeem ua kom daim ntawv muaj zog thiab txhim kho kev tsim daim ntawv. PolyDADMAC siv rau kev tswj cov tshuaj cuam tshuam hauv cov txheej txheem ua ntawv. Nws muab kev kho kom zoo dua ntawm cov suab los ntawm cov khoom siv tshuab thiab cov roj hmab los ntawm cov khoom siv coated. Siv rau hauv kev ncig luv luv ntawm lub tshuab ntawv los txhim kho kev khaws cia thiab dewatering. Tsis tas li ntawd, nws tuaj yeem siv los txhim kho kev ua haujlwm ntawm cov lim disk thiab cov flotators, thiab rau cationization ntawm cov khoom sau kom muab qhov siab tshaj plaws ntawm cov khoom sau.

Kev Lag Luam Textile

Hauv kev lag luam textile, nws kuj tseem siv tau rau kev ua tiav cov ntaub antistatic, yog li ua kom zoo dua ntawm cov ntaub.

Peb cov khoom muaj cov khoom zoo ruaj khov. Tom qab tau kuaj xyuas nruj heev, tag nrho nws cov ntsuas tau mus txog qib ua tus thawj coj hauv kev lag luam. Peb muaj ib pab pawg kws tshaj lij thiab cov khoom xa tuaj ruaj khov. Peb tuaj yeem pom zoo cov qauv khoom tsim nyog raws li koj cov xwm txheej siv.
