PolyDADMAC yog ib qho ua tau zoo cationic polymer. Nws yog dav siv hauv kev kho dej, papermaking, textiles thiab lwm yam kev lag luam vim nws cov txiaj ntsig zoo kawg nkaus hauv kev tshem tawm cov khib nyiab, decolorizing dej khib nyiab thiab txhim kho kev ua haujlwm pom. Raws li cov organic muaj txiaj ntsig zooCoagulant, kev nyab xeeb tuav, ntau npaum li cas thiab daim ntawv thov ntawm PDADMAC tau nyiam ntau yam. Tsab ntawv xov xwm no yuav muab cov lus qhia ntxaws ntxaws txog kev tuav pov hwm kev nyab xeeb, kev pom zoo ntau npaum li cas thiab cov kev coj ua zoo tshaj plaws ntawm cov tshuaj PDADMAC los pab koj txhim kho kev ua tau zoo thaum ua kom muaj kev nyab xeeb thiab ua raws.
PDADMAC yog cov dej-soluble, linear polymer nrog cov nqi zoo. Nws feem ntau muaj nyob rau hauv daim ntawv ua kua (20% -40% concentration), thiab qee zaum hauv cov ntawv hmoov rau kev siv tshwj xeeb. Nws yog sib xws nrog ntau yam pH tej yam kev mob (zoo los ntawm pH 3 txog 10) thiab ua tau zoo nyob rau hauv ob qho tib si qis thiab siab turbidity dej.
Cov khoom tseem ceeb ntawmPolyDADMAC:
* Cov tsos mob: Tsis muaj xim rau daj ntseg daj kua nplaum
* Ionic nqi: Cationic
* Solubility: Ua tiav dej soluble
pH: 4-7 (1% daws)
* Molecular hnyav: tuaj yeem sib txawv los ntawm qis mus rau siab nyob ntawm daim ntawv thov

Kev siv ntawm PDADMAC
PDADMAC feem ntau siv rau hauv cov hauv qab no:
1. Kev kho dej thiab cov dej khib nyiab: Raws li cov txheej txheem coagulant lossis coagulant pab, PDADMAC txhim kho sedimentation thiab sludge dewatering hauv nroog thiab kev kho dej khib nyiab.
2. Pulp thiab Ntawv Kev Lag Luam: Txhim kho kev khaws cia thiab tso dej, txhim kho cov ntawv zoo, thiab ua raws li kev kho rau cov thoob khib nyiab anionic.
3. Kev Lag Luam Textile: Ua raws li tus neeg sawv cev dye-kho, txhim kho xim ceev.
4. Oilfield thiab Mining: Siv rau kev qhia dej, kev kho sludge, thiab emulsification tawg.

Kev nyab xeeb ntawm PDADMAC
Txawm hais tias PDADMAC raug suav hais tias tsis muaj tshuaj lom, cov txheej txheem tuav kom raug yuav tsum ua raws li ib txwm ua kom cov neeg ua haujlwm muaj kev nyab xeeb thiab tiv thaiv ib puag ncig.
1. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE)
* Hnav cov hnab looj tes tiv thaiv tshuaj, khaub ncaws tiv thaiv, thiab tsom iav kev nyab xeeb.
* Nyob rau hauv rooj plaub ntawm aerosol los yog vapors, siv kev tiv thaiv ua pa tsim nyog.
2. Kev cia khoom
* Khaws rau hauv qhov chaw txias, qhuav, thiab qhov cua zoo.
* Khaws cov thawv ntim kom nruj.
* Tsis txhob ua kom khov lossis ua kom ntev ntev rau qhov kub thiab txias.
3. Kev Pabcuam Ua Ntej
* Kev sib cuag ntawm daim tawv nqaij: Yaug nrog dej kom ntau thiab tshem tawm cov khaub ncaws tsis huv.
* Tiv thaiv qhov muag: yaug qhov muag nrog dej tsawg kawg 15 feeb.
* Kev nqus pa: txav mus rau huab cua ntshiab thiab nrhiav kev kho mob yog tias cov tsos mob tshwm sim.
* Kev noj haus: Tsis txhob ntuav ntuav. Yaug qhov ncauj thiab nrhiav kev kho mob.
PDADMAC Dosage Guide
Qhov kev pom zoo ntawm PDADMAC yog nyob ntawm daim ntawv thov tshwj xeeb, cov yam ntxwv dej, thiab cov hom phiaj kho. Hauv qab no yog cov lus qhia dav dav dav dav:
| Daim ntawv thov | Hom Tshuaj |
| Haus dej Coagulation | 1-10 ppm |
| Industrial Wastewater | 10-50 ppm |
| Dye Fixing (Textile) | 0.5-2.0g / L |
| Papermaking Retention Aid | 0.1-0.5% ntawm qhov hnyav fiber ntau |
| Sludge Dewatering | 20-100 ppm (raws li cov khoom qhuav) |
Nco tseg: Nws raug nquahu kom ua cov ntawv xeem lub thawv lossis kev sim ua haujlwm los txiav txim siab qhov siv tau zoo tshaj plaws raws li qhov chaw tshwj xeeb.

Txoj kev thov
PDADMAC tuaj yeem muab ntxiv ncaj qha rau hauv cov dej ntws los yog sib xyaw nrog lwm cov tshuaj hauv kev siv tshuaj. Nov yog qee cov lus qhia rau cov txiaj ntsig zoo:
1. Dilution: PDADMAC kua tuaj yeem diluted nrog dej ntawm qhov sib piv ntawm 1: 5 mus rau 1: 20 ua ntej noj kom zoo dua dispersion.
2. Kev sib xyaw ua ke: xyuas kom meej meej thiab txawm tias sib xyaw hauv cov txheej txheem kev kho mob kom ua tiav qhov tsim floc.
3. Ib ntus: Yog tias siv nrog lwm cov flocculants (xws li, polyacrylamide), ntxiv PDADMAC ua ntej kom muaj sijhawm txaus txaus.
4. Kev saib xyuas: Tsis tu ncua saib xyuas turbidity, sludge ntim, thiab lwm yam tseem ceeb ntsuas los kho qhov ntau npaum li cas ntawm lub sijhawm.
Environmental Considerations
PDADMAC feem ntau suav tias yog ib puag ncig zoo thaum siv kom tsim nyog. Txawm li cas los xij, kev tso tawm ntau dhau tuaj yeem cuam tshuam rau lub neej hauv dej vim nws qhov muaj zog cationic. Ib txwm ua raws li cov cai hauv zos rau kev pov tseg cov dej khib nyiab thiab zam kev tso tawm tsis muaj kev tswj hwm rau hauv cov dej ntuj.
Txawm hais tias koj tab tom tswj hwm lub chaw kho mob hauv nroog, ua haujlwm hauv tsev textile dye tsev, lossis ua haujlwm hauv kev lag luam cov ntaub ntawv thiab ntawv, PDADMAC muaj kev ua tau zoo thiab cov txiaj ntsig zoo ib yam.
Yog tias koj tab tom nrhiav kev ntseeg siabPDADMAC tus neeg muag khoomnrog kev ruaj khov zoo thiab hloov pauv kev xaiv ntim, xav tiv tauj peb pab pawg kws tshaj lij rau kev daws teeb meem raws li koj qhov kev xav tau ntawm kev lag luam.
