Cov kev kho dej twg yuav tsum tau siv cov ion txauv resins?

Ion txauv resins feem ntau yog siv nyob rau hauv ntau yam kev lag luam, tshwj xeeb tshaj yog tshuaj thiab petrochemical, lub zog, mining thiab hlau, khoom noj khoom haus thiab dej haus, tshuaj, hauv nroog, semiconductor thiab lwm yam lag luam. Ion txauv resins tuaj yeem yog ib qho kev daws teeb meem zoo rau ntau yam kev siv, suav nrog dej muag, ntxuav, sib cais, polishing thiab pretreatment, los tiv thaiv tom qab cov khoom siv thiab txhim kho kev ua haujlwm. Yog li, cov khoom siv kho dej twg yuav tsum tau siv ion txauv resins?
Lub hardness ntawm cov dej kho yuav tsum tau txo
Hardness hais txog cov dej uas muaj cov ntxhia hauv cov ntsiab lus siab, feem ntau muaj cov calcium thiab magnesium ions. Txawm hais tias cov ntxhia cov ntsiab lus tau txais - txawm tias nyiam - rau cov dej haus, qhov nyuaj tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hauv kev lag luam, xws li boilers, txias yees, thiab cov kav dej. Softened resins muaj txiaj ntsig zoo hauv kev txo cov tawv nqaij thiab tshwj xeeb tshaj yog tsim nyog yog tias lub chaw siv lub boiler qis.
Softening resins siv muaj zog acid cation (SAC) resins pauv rau cov tawv ions ntawm sodium ions. Qhov no txhais tau hais tias siv cov tshuaj brine uas muaj kev nyab xeeb thiab tus nqi qis kom rov tsim cov khoom muag muag. Txawm li cas los xij, txhawm rau kom tsis txhob muaj kev hloov pauv ntau dhau thiab lub sijhawm tsis tsim nyog, softening resins yog qhov zoo tshaj plaws rau cov ntawv thov uas tsis tshua muaj cov khoom tawg tag (TDS), thaum lwm cov tswv yim, xws li txiv qaub softening, feem ntau zoo dua rau kev kho cov dej nrog cov hardness siab.
Yuav tsum muaj dej purity siab
Ion txauv resin demineralization thiab deionization tsim cov dej purity siab thiab tej zaum yuav yog qhov kev xaiv zoo rau kev kho mob siab boiler feedwater los yog lwm yam kev siv nyob rau hauv tshuaj, hwj chim, electronics, nuclear los yog lwm yam lag luam. Piv nrog rau softened resins, polished resin demineralization cuam tshuam nrog cov txheej txheem ntau kauj ruam. Hauv thawj kauj ruam, cov dej ntws tau dhau los ntawm cation txauv resin kom tshem tawm cov hardness, sodium thiab lwm yam hlau, thiab nyob rau hauv lub kauj ruam thib ob, cov dej ntws yog kho nrog anion exchange resin uas tshem tawm cov anions xws li carbonates, chlorides, silica thiab anions. . Cov sulfate. Qee zaum, ib kauj ruam thib peb ntxiv los daws cov alkalinity ntawm cov kwj deg. Txawm hais tias tus nqi ntxiv cuam tshuam nrog ntau lub tshuab, polished resin demineralization feem ntau yog tus qauv kom tau raws li cov kev xav tau dej ntshiab.
Koj yuav tsum tshem tawm cov alkalinity
Alkalinity, los yog muaj cov pa roj carbon dioxide yaj (CO 2), bicarbonate (HCO 3), carbonate (CO 3), lossis hydroxyl pawg (OH) hauv dej tuaj yeem cuam tshuam rau cov txheej txheem kub kub, xws li cov npuas dej ntau dhau thiab cov khoom seem hauv boilers. . Thaum cov pa phem alkaline hnov ​​​​mob rau carbonic acid thiab hydroxide, lawv tuaj yeem ua rau raug nqi scaling thiab corrosion hauv boilers, kav dej thiab lwm yam khoom siv. Kev tshem tawm alkalinity tuaj yeem ua rau lub neej ntev ntawm cov cuab yeej siv thiab txuag cov nqi khiav lag luam, txawm li cas los xij, xaiv txoj cai resin de-alkalinity lub tswv yim tuaj yeem nyob ntawm cov yam xws li lub hom phiaj alkalinity, TDS cov ntsiab lus, thiab kev ua haujlwm muaj peev xwm.
Cov hlau yuav tsum tau concentrated lossis tshem tawm
Resin system cov ntaub ntawv siv feem ntau yog siv los mloog zoo thiab cais cov hlau hauv cov kev daws teeb meem, qhov tseeb uas tau ua rau muaj kev loj hlob ntawm cov khoom siv hluav taws xob, semiconductor, mining, thiab hlau industries. Nyob ntawm qhov nyuaj ntawm cov txheej txheem los yog cov dej khib nyiab, chelating resins tuaj yeem siv los cais ntau yam hlau, suav nrog cadmium, chromium, tooj liab, cyanide, txhuas, kub, mercury, nyiaj, thiab zinc. Yog tias cov nroj tsuag tab tom nrhiav txoj hauv kev kom rov qab tau cov hlau muaj txiaj ntsig los ntawm cov kwj deg, lossis kom ua tau raws li cov kev xav tau ntawm cov hlau tawm, ces chelate resins yuav yog qhov kev daws teeb meem zoo tshaj plaws.
Cov cuab yeej siv los txhim kho qhov zoo ntawm cov dej ntau lawm
Membrane filtration feem ntau siv tau los tshem tawm cov kab mob tib yam li cov resins, tab sis cov membranes tsis muaj kev xaiv ntawm cov resins. Vim hais tias cov resins tuaj yeem raug tshem tawm rau cov ions tshwj xeeb thaum tawm hauv cov khoom xav tau hauv cov tshuaj, cov resin pauv yuav yog ib qho kev nyiam sib cais yog tias koj xav ua kom zoo dua thiab txhim kho cov dej ua tau zoo. Piv txwv li, hauv kev lag luam zaub mov thiab dej haus, resins tuaj yeem siv los tshem tawm cov xim tsis xav tau, saj, thiab tsw tsis tsim cov khoom pov tseg.
