I-polydadmac (poly dialtimethylammonium chloride)

Kungani Khetha iPolydadMac?

Njengoba ububanzi be-china buphethwe isikhathi eside yizinto zokwakha ama-graninicoous fiber raw, kanye nemicu yezitshalo ze-herbaceous imfushane, ngokuqukethwe okuphezulu kwama-heterocytes, ipulpp yotshani inokugcinwa kwamanzi okuphansi kanye nokuhlunga kwamanzi okuhle entweni ephithizelayo.

I-PolydadMac ingathuthukisa inkinga yokuhlunga kwamanzi okuphansi kanye nokuhlupheka okubi kakhulu kwinqubo yokuphambana, thuthukisa umkhiqizo kanye nokusetshenziswa okubonakalayo okuluhlaza, ukunciphisa izindleko zamathani ephepha nokungcoliswa kwephepha. I-PolydadMac nayo ingathuthukisa ukusebenza kwe-fieltration yamanzi ye-pulp kanye nokwakhiwa kwephepha lephepha.

Le ndatshana iphenya ngokuthi izici ze-adsorption, ukugcinwa, kanye nezimpawu ze-filltration of polydadMac ezinezinsimbi ezihlukile zamangqamuzana njengezengezo kwi-pulp yomhlanga ehlanganisiwe, bese uthola isiphetho esilandelayo.

1.Aadorption of Polydadmac ku-Reed Pulp

Isisindo esincane se-molecular se-polydadmac, ngokwengeziwe ukwehla kwezinga elikhulayo ngenani elandayo le-AUxiliary, okungenzeka ngenxa yokuthi lincane kakhulu ukuthi isisindo esincane se-polydadmac, amandla amakhulu okubamba ama-anions. I-polydadmac engaphansi iyadingeka ngenani elifanayo le-antion ohlelweni olugcwele.

Umphumela we-2.Filtering of PolydadMac

Ngomthamo okhulayo wePolydadMac, iziqu ze-Filtration degree zivame ukwehla bese zikhuphuka, futhi iziqu ze-Filtration zisondele kakhulu noma zidlula ezingenalutho lapho inani lokungezelela lifinyelela futhi lidlula i-0.8%. Lokhu kusho ukuthi i-polydadmac eningi kakhulu ayikwazi ukusiza ukufotsa, kepha yabi kakhulu ukugcwala kwamanzi kwepulp. Lokho kusho ukuthi i-polydadmac ehlukile ye-molecularmac yayinomphumela wokuhlunga okungcono ngaphambi kokuba igcwalise inkokhiso engemihle epulpini fiber ebusweni.

I-3.Renet umphumela wePolydadMac

Njengoba umthamo wePolydadmac uyanda, ukugcotshwa kwamanzi okumhlophe kwe-puletha yomhlanga kancane kancane kuncipha kuqala, bese kuphinde kwanda. Lolu phenyo lubonisa ukuthi ukwengeza i-polydadMac ku-Reed Pulp kungathuthukisa kakhulu ukugcinwa kwemicu emifushane nezinto ezinhle nokusetshenziswa kwama-drainage. Kutholakale ukuthi umthamo ofanele wePolydadMac akathintekanga ngesisindo sawo se-molecular; Uma kuncane isisindo samangqamuzana sePolydadMac, okungcono umphumela wokugcina kabusha. Kepha umehluko awubonakali, futhi isisindo esihlukile se-molecular polydadmac sinemiphumela engcono yokugcinwa ebusweni bemicu ye-pulp ye-pulp ngaphambi kwamacala amabi.

Isiphetho:

I-1.PolyDadMac enezinsimbi ezahlukahlukene zamangqamuzana ine-filltration enhle yokuhlunga kanye nemiphumela yokugcina ku-pulp yomhlanga;
2.I-2.Iminye imiphumela engcono yokuhlunga kanye nemiphumela yokugcina i-areieaieved lapho inani le-polydadmac lisetshenziswa lingaphansi kwecala elibi ngaphezulu kwemicu ye-pulp fibers;

3.LOW Lolecular Weight Polydadmac hasgood Retation Returnued.High Molecular Weight inomphumela omuhle wokuhlunga. Kodwa-ke, awukho umehluko obalulekile ekusebenzeni kwawo kokusiza ekusizeni kwezomhluzi kanye nokugcinwa.
