PolyDADMAC yog ib qho polymer cationic ua haujlwm tau zoo heev. Nws siv dav hauv kev kho dej, ua ntawv, textiles thiab lwm yam teb vim nws cov txiaj ntsig zoo kawg nkaus hauv kev tshem tawm cov khoom seem, tshem tawm cov xim dej khib nyiab thiab txhim kho kev ua haujlwm lim dej. Ua ib qho organic ua haujlwm tau zoo heev.Cov tshuaj coagulant, kev siv tshuaj zoo, kev noj tshuaj thiab kev siv PDADMAC tau txais kev saib xyuas ntau. Tsab xov xwm no yuav muab cov lus qhia ntxaws ntxaws txog kev siv tshuaj zoo, kev noj tshuaj pom zoo thiab kev siv tshuaj zoo tshaj plaws ntawm PDADMAC los pab koj ua kom zoo dua thaum ua kom muaj kev nyab xeeb thiab ua raws li txoj cai.
PDADMAC yog ib hom polymer uas yaj tau hauv dej, linear polymer uas muaj cov nqi zoo. Feem ntau nws muaj nyob rau hauv daim ntawv kua (20% -40% concentration), thiab qee zaum hauv daim ntawv hmoov rau cov ntawv thov tshwj xeeb. Nws sib xws nrog ntau yam pH (zoo los ntawm pH 3 txog 10) thiab ua haujlwm tau zoo hauv ob qho dej turbidity qis thiab siab.
Cov khoom tseem ceeb ntawmPolyDADMAC:
* Tsos: Tsis muaj xim rau cov kua daj daj ntseg
* Tus nqi ionic: cationic
* Kev yaj: Dej yaj tag nrho
* pH: 4–7 (1% kua)
* Qhov hnyav molecular: Yuav txawv ntawm qis mus rau siab nyob ntawm daim ntawv thov

Kev Tswj Xyuas PDADMAC Kom Muaj Kev Nyab Xeeb
Txawm hais tias PDADMAC suav tias tsis muaj tshuaj lom, cov txheej txheem kev tuav pov hwm kom zoo yuav tsum tau ua raws li kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb thiab tiv thaiv kev cuam tshuam rau ib puag ncig.
1. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE)
* Hnav cov hnab looj tes uas tiv taus tshuaj lom neeg, khaub ncaws tiv thaiv, thiab cov tsom iav tiv thaiv kev nyab xeeb.
* Yog tias muaj aerosol lossis vapors, siv cov khoom tiv thaiv kev ua pa kom tsim nyog.
2. Cov Cai Khaws Cia
* Khaws cia rau qhov chaw txias, qhuav, thiab muaj cua nkag tau zoo.
* Khaws cov thawv kom kaw ruaj ruaj.
* Tsis txhob cia khov lossis raug kub ntev.
3. Cov Kev Ntsuas Kev Pab Thaum Muaj Xwm Ceev
* Kev sib chwv ntawm daim tawv nqaij: Yaug nrog dej ntau thiab tshem cov khaub ncaws uas muaj kuab paug.
* Kev sib chwv qhov muag: Yaug qhov muag nrog dej tsawg kawg 15 feeb.
* Kev ua pa: Tsiv mus rau qhov chaw muaj huab cua ntshiab thiab nrhiav kev kho mob yog tias cov tsos mob tseem muaj.
* Haus: Tsis txhob ua kom ntuav. Yaug qhov ncauj thiab nrhiav kev kho mob.
Daim Ntawv Qhia Txog Kev Siv PDADMAC
Qhov koob tshuaj zoo tshaj plaws ntawm PDADMAC nyob ntawm seb daim ntawv thov tshwj xeeb, cov yam ntxwv ntawm dej, thiab cov hom phiaj kho mob. Hauv qab no yog cov lus qhia dav dav txog kev siv tshuaj:
| Daim Ntawv Thov | Cov Tshuaj Li Cas |
| Kev Kho Mob Dej Haus | 1–10 ppm |
| Cov Dej Pov Tseg Hauv Kev Lag Luam | 10–50 ppm |
| Kev Kho Xim (Textile) | 0.5–2.0 g/L |
| Kev Pab Txhawb Nqa Ntawv | 0.1–0.5% ntawm qhov hnyav ntawm cov fiber qhuav |
| Kev Tshem Tawm Sludge | 20–100 ppm (raws li cov khoom qhuav) |
Lus Cim: Nws raug pom zoo kom ua qhov kev sim tshuaj hauv lub thawv lossis kev sim ua ntej kom paub meej tias cov tshuaj twg zoo tshaj plaws rau hauv qhov chaw.
