Ntawm cov kev kho dej khib nyiab pov tseg, luam ntawv thiab zowing wastewater yog ib qho nyuaj tshaj plaws-kom-kho cov khib nyiab. Nws tau muaj ntau yam sib xyaw, muaj txiaj ntsig chroma, siab siab, thiab yog qhov nyuaj rau kev ua txhaum. Nws yog ib qho ntawm qhov loj tshaj thiab nyuaj-rau-kho kev lag luam wasterters uas ua rau ib puag ncig ua qias. Qhov kev tshem tawm ntawm Chroma yog qhov nyuaj tshaj ntawm cov teeb meem.
Ntawm ntau cov luam ntawv thiab zas dej kom huv txoj kev kho kom zoo, kev siv cov txheej txheem sib xyaws yog qhov kev siv dav dav hauv kev lag luam. Tam sim no, cov tshuaj uas pom zoo siv rau hauv textile luam ntawv thiab tawg ntawm cov lag luam hauv kuv lub teb chaws yog ali-based frocculants. Cov nyhuv decolorization yog cov tsis zoo, thiab yog tias yuav luag tsis muaj hlau, thiab tseem yuav muaj kev phom sij, thiab tseem muaj kev phom sij rau tib neeg lub cev thiab ib puag ncig ib puag ncig.
Dicyandiamide Formalrehyde Resin Resin Decoloring Tus Neeg Sawv Cev yog ib qho organic polymer flocculant, Quas ammonium ntsev hom. Piv nrog cov tsoos ib txwm muaj flocculancults, nws muaj kev nrawm nrawm, thiab cuam tshuam los ntawm coexisting salts, pH thiab cov txiaj ntsig zoo li cuam tshuam kub.
Lub Dicyandiamide Formenialhyde resin resin decoloring tus neeg sawv cev yog flocculant tsuas yog siv rau kev txiav tawm thiab cod tshem tawm. Thaum siv nws, nws raug nquahu kom kho tus nqi PH ntawm cov neeg lim dej mus rau nruab nrab. Thov sib txuas lus nrog cov kws tshaj lij rau cov kev siv kev siv tshwj xeeb. Raws li ntau txoj kev koom tes tawm tswv yim los ntawm kev luam ntawv thiab tawg manufacturers yog tias dictandiamide resin decolorizer muaj cov txiaj ntsig zoo ntawm kev luam tawm thiab zas ntoo. Tus nqi tshem tawm Choma tshem tawm tuaj yeem ncav cuag ntau dua 96%, thiab kev tshem tawm tus lej ntawm COD tau los tau ntau dua 70%.
Organic Polymer Flocculants tau siv thawj zaug hauv xyoo 1950 feem ntau yog polyacrylamide dej tuaj yeem faib ua cov tsis yog-ionic, anionic, thiab cationic. Hauv tsab xov xwm no, peb yuav nkag siab cov Acrylamide Polymer FormandiaMide Resin decolorizing flocculant uas yog Quanic Amine polymer Flocculants.
Cov khoom siv dag dag formandiahyde decolorizing flocculant yog ua kom muaj acrylamide, ces refkinghyde aquely aqueous auchel, thiab tom qab ntawd txias thiab qaib acid. Cov khoom yog feeb los ntawm evaporation thiab lim kom tau txais ib quanized acrylamide monomer.
Lub ntsuas hluav taws xob fictandiamide-formaldehyde condens polymer decolorizing foccculant tau qhia nyob rau xyoo 1990. Nws muaj qhov tshwj xeeb heev tshwj xeeb ntawm kev tshem cov xim ntawm zas xim wastewater. Hauv kev kho cov xim high-xim thiab siab-concectorater, tsuas yog polyacrylamide lossis polyacrylamide yog siv. Polyaluminium chloride flocculant tsis tuaj yeem tshem tawm cov xim, thiab tom qab ntxiv cov dej tsis zoo, nws ne destalilizes thaum kawg, muaj cov floccules tau tsim, uas tuaj yeem nqus cov zas xim molecules tom qab focculation thiab destabilization, thiaj li ua tiav lub hom phiaj ntawm decolorization.
Yuav Siv Decolorizer Li Cas:
Cov txheej txheem ntawm kev siv decolorizing flocculant yog zoo li ntawm polyacrylamide. Txawm hais tias tus qub yog nyob rau hauv cov kua ua kua, nws xav tau kom diluted ua ntej nws tuaj yeem siv. Cov chaw tsim khoom pom pom zoo tias nws yuav diluted los ntawm 10% -50%, thiab tom qab ntawd ntxiv rau cov dej khib nyiab thiab ua kom tiav. Ua Alum Paj. Cov xim muaj xim rau hauv cov xim dej ntws tawm hauv cov xim dej ntws tawm hauv dej, thiab yog nruab nrog cov dej lossis huab cua ua kom tiav kev sib cais.
Hauv kev luam ntawv thiab dyeing, textile thiab lwm yam kev lag luam, kev noj dej, dej tau noj ntau heev thiab rov siv dua tus nqi tsawg. Yog li ntawd, cov khib nyiab ntawm cov khoom siv dej muaj ntau heev. Yog tias cov txheej txheem tau siv los ua cov kev kho siab tshaj plaws thiab kev rov ua dua tshiab ntawm cov xim hluav taws xob, tsis yog nws tuaj yeem txo cov tshuaj tua dej tshiab, uas yog Ntawm kev loj thiab deb-nce qhov tseem ceeb rau kev txhawb nqa kev txhim kho kev txhim kho ntawm luam ntawv, Dyeing thiab Textile Industries.
Execermpted los ntawm kev yuav yooj yim.
