Feem ntau siv deflocculant tau muab faib ua peb yam kom nthuav dav.Ua ntej, hom deflocculants feem ntau, nrog rau cov organic thiab inorganic, tau qhia.Qhov thib ob, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm deflocculant yog tham txog, nrog rau cov txheej txheem ntawm adsorption, electrolysis thiab gel.Thaum kawg, daim ntawv thov teb ntawm deflocculant raug tshuaj xyuas, uas feem ntau koom nrog kev kho dej, dej phwj tuaj kho thiab kev lag luam textile.Txhawm rau ua kom tiav, daim ntawv no muab cov lus piav qhia dav dav ntawm cov khoom siv deflocculants.
1, hom deflocculating tus neeg sawv cev
Deflocculants feem ntau muab faib ua cov organic thiab inorganic ob pawg.Organic deflocculants suav nrog cov organic polymers thiab cov organic tsis tshua muaj molecules.Organic polymer deflocculants yog cov khoom siv polymer, xws li polyaluminum chloride thiab polyacrylamide.Organic low molecular deflocculants yog ib co me me molecular organic tebchaw, xws li hydroxyl tebchaw thiab ketones.
Inorganic deflocculants xa mus rau hlau ntsev, xws li txhuas ntsev thiab hlau ntsev.Aluminium ntsev muaj xws li txhuas chloride, aluminium sulfate thiab polyaluminium chloride.Hlau ntsev muaj xws li ferric chloride thiab ferric sulfate.Inorganic deflocculants feem ntau muaj cov nyhuv flocculation zoo dua thiab ruaj khov.
2. Lub hauv paus ntsiab lus ntawm deflocculating tus neeg sawv cev
Cov txheej txheem ntawm deflocculant feem ntau suav nrog adsorption, electrolysis thiab gel.Lub adsorption mechanism yog hais txog lub cev los yog tshuaj adsorption ntawm lub deflocculant nrog rau saum npoo ntawm cov teeb meem raug tshem tawm, thiab cov nyhuv attraction ua rau cov teeb meem tshem tawm ua ke rau hauv flocculate thiab precipitate down.Lub tshuab electrolytic yog hais txog cov tshuaj tiv thaiv electrolytic ntawm cov tshuaj ionized nyob rau hauv lub deflocculant thiab cov nqi hais nyob rau hauv cov teeb meem tshem tawm los ua ib tug precipitate thiab ua tiav lub hom phiaj ntawm flocculation.Lub gel mechanism txhais tau hais tias cov deflocculant tsim ib gel nyob rau hauv cov kev daws, thiab ua tiav cov nyhuv flocculation los ntawm kev nthuav dav, adsorption thiab sib sib zog nqus nag lossis daus ntawm cov gel.
3. Daim ntawv thov teb ntawm deflocculant
Deflocculant yog dav siv hauv kev kho dej, kev kho dej phwj thiab kev lag luam textile.Hauv kev kho dej, deflocculant tuaj yeem siv los tshem tawm cov impurities xws li tshem tawm cov khib nyiab, pigments thiab cov hlau hnyav hauv dej txhawm rau txhim kho qhov pom tseeb thiab zoo ntawm cov dej.
Hauv kev kho cov dej phwj tuaj, cov deflocculant tuaj yeem ua rau cov teeb meem raug tshem tawm hauv cov dej phwj tuaj, kom cov dej phwj tuaj yeem huv thiab ua tau raws li tus qauv tso tawm.Tsis tas li ntawd, cov tshuaj deflocculants tseem muaj cov ntawv thov tseem ceeb hauv kev lag luam textile, uas tuaj yeem tshem tawm cov dyes thiab cov organic tshuaj hauv cov dej khib nyiab thiab txo cov pa phem rau ib puag ncig.
Cov ntsiab lus: Los ntawm kev piav qhia ntau yam, cov ntsiab cai ntawm kev ua haujlwm thiab daim ntawv thov ntawm cov khoom siv deflocculants, peb tuaj yeem pom tias deflocculants ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv ib puag ncig thiab kev tsim khoom lag luam.Ntau hom deflocculants muaj cov yam ntxwv sib txawv thiab daim ntawv thov ntau yam, yog li nws yuav tsum xaiv cov deflocculants tsim nyog raws li cov xwm txheej tshwj xeeb hauv kev siv tswv yim.
