Lub luag hauj lwm ntawm polyacrylamide hauv luam ntawv thiab cov nroj tsuag dyeing
Peb yog ib lub tuam txhab luam ntawv loj hauv Shenzhen Tuam Tshoj. Peb muaj cov phau ntawv luam tawm, phau ntawv xov xwm luam ntawv, phau ntawv luam ntawv, phau ntawv nyuaj, phau ntawv luam tawm, phau ntawv luam tawm, phau ntawv luam tawm, lub thawv ntim, daim qhia ntawv, txhua yam ntawm PVC, cov ntawv luam tawm, ntawv sau cia, hom tshwj xeeb ntawv xim luam tawm khoom, kev ua si cardand li ntawd.

Nrog txoj kev loj hlob ntawm cov kev lag luam textile zas, qhov tawm ntawm luam ntawv thiab dyeing wastewater uas ua tsis tau raws li cov qauv ua qhov loj dua. Lub tuam tsev ua dej num kuj tau kuaj xyuas cov dej tawm kom nruj heev. Yog li ntawd, ntau lub chaw lag luam tsis tuaj yeem coj nws yooj yim thiab yuav tsum ntxiv dag zog rau cov txheej txheem emission. Saib xyuas thiab tsis txhob poob me me. Kev kho cov dej phwj hauv kev luam thiab dyeing kev lag luam feem ntau siv polyacrylamide, yog li cas lub luag hauj lwm tsis yog polyacrylamide ua si hauv textile printing thiab dyeing? Dab tsi yog nws txoj kev siv thiab kev ceev faj? Cov nram qab no yog cov ncauj lus qhia ntxaws txog cov tshuaj Shouxin.
Lub luag haujlwm ntawm cov polyacrylamide hauv kev luam tawm thiab kev lag luam:
1. Nyob rau hauv cov kev lag luam textile, polyacrylamide flocculant ua tus neeg saib xyuas koj lub cev thiab xov tooj rau cov ntaub ntawv tom qab kho tuaj yeem tsim cov txheej txheem tiv thaiv, tiv thaiv npog thiab pwm-resistant;
2. Lub flocculant ua tus kws kho mob tom qab tuaj yeem tiv thaiv kev tiv thaiv hluav taws xob thiab hluav taws kub ntawm cov ntaub;
3. Thaum siv los ua luam ntawv thiab dyeing auxiliary, nws tuaj yeem ua rau cov khoom muaj zog ua kom ceev nrooj thiab siab vividness, thiab tseem siv tau ua ib qho tsis-silicon polymer stabilizer rau tshuaj dawb;
4. Qhov no yog tus yuam sij rau kev kho kom huv si ntawm cov dej khib nyiab los ntawm kev luam ntawv thiab kev lag luam textile.
Kev luam tawm thiab dyeing wastewater nta:
Printing thiab dyeing wastewater muaj ntau cov dej. Kev luam thiab dyeing siv 100 mus rau 200 tons ntawm cov dej ib ton ntawm textiles, ntawm uas 80 mus rau 90% ua cov dej khib nyiab. Textile luam ntawv thiab dyeing wastewater muaj cov yam ntxwv ntawm cov dej ntim loj, cov organic tshuaj phev ntau, cov dej loj thiab hloov dej loj. Nws yog ib qho ntawm cov chaw muaj dej khib nyiab uas kho nyuaj. Lub wastewater muaj dyes, slurries, additives, roj cov neeg ua hauj lawm, kua qaub thiab alkali, thiab fiber. Impurities, cov ntaub ntawv xuab zeb, inorganic ntsev, lwm yam zoo li
Qhov tseem ceeb rau txoj kev kho mob coagulation ntawm luam ntawv thiab dyeing cov dej khib nyiab yog xaiv ib lub tshuab flocculant. Cov flocculants feem ntau siv rau hauv kev kho mob ntawm kev luam ntawv thiab dyeing cov dej khib nyiab yog cov khoom txhuas feem ntau yog aluminium sulfate, hlau sulfate, ferric chloride thiab cationic polyacrylamide nyob rau theem tom ntej. Cov flocculants Nws yog ib qho zoo rau kev kho qee cov dej tsis muaj dej tsis muaj dej, xws li disperse dyes, vat dyes, sulfur dyes, COD thiab chromaticity tshem tawm cov nqi siab heev.
Lus Qhia:
1. Txoj kev tshem tawm: Siv cov khoom sib xyaws rau hauv qhov kev tov ntawm qhov dej ntawm 1 ‰ - 5 ‰ ua ntej siv kom ceev nrooj. Thaum muab cov tshuaj ntxiv, nws yuav tsum tau txais txoj kev los ntawm kev noj cov tshuaj hauv tsev neeg, maj mam muab tso rau hauv dej, thiab tom qab ntawd muab pov rau hauv dej.
2. Ntxiv rau qhov kev daws teeb meem: Feem ntau, ib qho kev tov ntawm 0.5 rau ‰ -1 ‰. Txawm li cas los xij, yog hais tias muaj cov concentration thiab high viscosity ntawm qhov kev ncua, nws yog qhov pom zoo kom ntxiv dilute cov kua tshuaj to 0.1%. Nws yuav yooj yim mus sib tov thiab hnyav txaus teebmeem.
3. Lub cation muaj ib phaus molecular tshaj lub anion thiab viscosity kuj weaker tshaj qhov anion. Yog li, cov ntaub ntawv cation thiab nonionic ratio concentration cov qauv yog me ntsis siab tshaj qhov anion. (Nyob ntawm qhov teeb meem no, nws tseem tuaj yeem hloov kho qhov qoob lag luam kom muaj siab tuaj raws li cov dej ntws, thiab qhov tsis muaj qhov tsis muaj peev xwm ua rau lub cev tsis zoo). Qhov kev pom zoo concentration yog 5 ‰ -1%.
Ceev faj:
1. Thaum npaj PAM kua dej, nws yuav tsum tau nqa tawm hauv txha hniav, nkev, txhuas lossis yas nruas. Nws yuav tsum tsis txhob npaj thiab muab cia rau hauv cov thawv ntim.
2. Thaum muab daws, yuav tsum tau saib xyuas kom maj mam muab cov khoom ntxiv rau cov dissolver nrog cov nplaum thiab cua sov ntsuas. Zam kev nruj zuj zus, npaj cov tshuaj ntawm ib qho chaw uas tsim nyog, thiab tsis txhob muaj qhov sib txeeb ua kom ntev ntev. Nws yog pom zoo tias qhov stirrer yuav 60-200 rpm, txwv tsis pub lub polymer yuav degraded thiab cov nyhuv yuav cuam tshuam.
3, PAM aqueous solution yuav tsum npaj kom txhij rau kev siv tam sim no, thaum cov tshuaj muab tso rau ntev, nws cov kev ua haujlwm yuav maj mam txo nyob ntawm seb cov dej zoo li cas.
4. Tom qab cov kua dej uas muaj flocculant aqueous solution tau ntxiv rau qhov kev ncua, yog tias tus nplawm tseem khaus ntev heev, qhov uas twb tau ua tiav lawm yuav raug rhuav tshem.
