Ukuhlola i-PolyDADMAC

Ukuhlola Ubudlelwano Phakathi Kwesisindo Se-Molecular, Viscosity, Okuqukethwe Okuqinile, kanye Nekhwalithi ye-PolyDADMAC

I-PolyDADMAC (eyaziwa nangokuthi “i-polydiallyl dimethyl ammonium chloride”) iyi-polymer ye-cationic esetshenziswa ezinqubweni zokwelashwa kwamanzi. Ibaluleke kakhulu ngenxa yemiphumela yayo emihle yokugeleza kanye ne-coagulant. Njengomhlinzeki kanye nomsabalalisi wamakhemikhali okwelashwa kwamanzi, kubalulekile ukuqonda ubudlelwano phakathi kwesisindo sama-molecule, i-viscosity kanye nokuqukethwe okuqinile kwe-PolyDADMAC kanye nekhwalithi yomkhiqizo. Kulesi sihloko, sizohlola ubudlelwano phakathi kwalezi zinkomba kanye nendlela yokukhetha imikhiqizo esezingeni eliphezulu ekufanele.

Isisindo sama-molecule, i-viscosity kanye nokuqukethwe okuqinile kwe-PolyDADMAC kuyimingcele ebalulekile ethinta umphumela wayo. Zihlobene. Okulandelayo incazelo eningiliziwe yazo kanye nencazelo eningiliziwe yobuhlobo bazo:

1. Ubudlelwano

Isisindo sama-molecular sibhekisela kubude obujwayelekile be-PolyDADMAC polymer chain.

Izisindo eziphakeme zama-molecule ngokuvamile zisho amaketanga amade e-polymer, okungathuthukisa amakhono okugoqana kwe-PolyDADMAC. Futhi izisindo eziphakeme zama-molecule ngokuvamile zinikeza imiphumela ethile yokuhlanganisa, okuvumela izinhlayiya ezincane emanzini ukuthi zihlanganiswe ndawonye. Kungathuthukisa imiphumela yokwelashwa kwamanzi.

Kodwa-ke, isisindo sama-molecule esiphezulu kakhulu singaholela ekuqineni ngokweqile, okuthinta ukusebenza.

Isisindo sama-molecule siyisibonakaliso esibalulekile sekhwalithi ye-PDADMAC ngoba sithinta ngqo umphumela wokusetshenziswa kwayo.

Isisindo sama-molecule e-PDADMAC ngokuvamile sisukela ku-50,000 kuya ku-700,000Da, futhi imikhiqizo enesisindo sama-molecule esiphezulu kakhulu kufanele ifinyelele ku-3,000,000Da.

2. Ukujiya

I-Viscosity ibhekisela ekumelaneni kwesisombululo se-PolyDADMAC ukugeleza.

Ngokuvamile i-viscosity ingu-80-12,000mPa.s, futhi kukhona ne-PolyDADMAC ene-viscosity ephezulu ene-viscosity engaphezu kuka-100,000. I-Viscosity ihlobene eduze nesisindo sama-molecule, futhi isisindo sama-molecule esiphezulu sibangela i-viscosity ephezulu. Futhi i-viscosity ithinta ukuncibilika nokuhlakazeka kwe-PDADMAC, kanye nokusebenza kwayo ekusebenzeni. Uma i-viscosity iphakeme kakhulu, i-viscosity ephezulu ingadala ubunzima bokusebenza (ukudlulisa nokunciphisa, njll.) I-Viscosity iyipharamitha ebalulekile yokulinganisa ikhwalithi ye-PDADMAC ngoba ibonisa isisindo sayo sama-molecule kanye nokusebenza kokusetshenziswa., kuyilapho i-PolyDADMAC ene-viscosity ephansi inokuguquguquka okuhle futhi kulula ukuyipompa.

3. Okuqukethwe okuqinile

Okuqukethwe okuqinile kubhekisela kumaphesenti esisindo se-polymer kusisombululo se-PolyDADMAC.

Okuqukethwe okuphezulu okuqinile kusho ukunciphisa izindleko zokugcina kanye nokuthutha. Kodwa-ke, uma umkhiqizo onesisindo sama-molecule esiphezulu kakhulu ulungiswa njengesixazululo esingu-40%, awukwazi ngisho nokuthululwa esigubheni.

Okuqukethwe okuqinile kwe-PolyDADMAC kungu-10% noma u-50%, okungukuthi, ingxenye yezinto ezisebenzayo zangempela esixazululweni

Ngokuvamile, okuqukethwe okuqinile kwe-PolyDADMAC esikuthengisayo kungaba ngu-40%. Siphinde sibe nezinye izincazelo zokuqukethwe okuqinile.

Ungahlolaincazelo yomkhiqizo enemininingwane ye-PolyDADMACukuze uthole imininingwane ethile kanye nezinkomba ezinemininingwane ze-PolyDADMAC.

Ubudlelwano phakathi kwabo:

Isisindo sama-molecule kanye nokubonakala kwawo:

Ngokuqukethwe okufanayo okuqinile, lapho isisindo sama-molecule siphakeme, kulapho i-viscosity iba nkulu khona.

Uma isisindo sama-molecule sikhulu, kulapho i-viscosity iba phezulu khona.

Okuqukethwe okuqinile kanye nokuthamba:

Ngesisindo esifanayo sama-molecule, lapho okuqukethwe okuqinile kuphakeme, kulapho i-viscosity iba nkulu khona.

Isisindo sama-molecule, okuqukethwe okuqinile, kanye nokusebenza:

Uma iqinile, isisindo sama-molecule siphakeme, umphumela uba ngcono, kodwa i-viscosity izokwanda.

Indlela yokukhetha i-PolyDADMAC ekufanele

Ukuchacha okunengqondo: qinisekisa ukugeleza kwamanzi, ukuncibilika kalula, kanye nokusebenza kahle kokugeleza kwamanzi.

Uma udinga ukuthola umhlinzeki omusha ozothenga i-PolyDADMAC, khona-ke kufanele uqale unqume ukwakheka kwekhwalithi yamanzi akho ukuze umhlinzeki wakho akwazi ukukusiza ukhethe imodeli engcono. Noma ungatshela umhlinzeki uhlobo kanye nemodeli ye-PolyDADMAC owayisebenzisa ngaphambilini. Noma ungathumela i-PolyDADMAC yakho ekhona kumhlinzeki wakho omusha futhi ubavumele bakusize uhlaziye futhi ukhethe. Ukuhlolwa kwesampula kwe-PolyDADMAC entsha kubaluleke kakhulu, futhi kufanele wenze ukuhlolwa ngokucophelela ukuze unqume ukuthi imodeli ikufanele yini.

NjengochwephesheUmhlinzeki we-PolyDADMAC, singakunikeza izinsizakalo zokukhetha futhi sikuthumelele amasampula amahhala. Uma unezidingo, sicela usithinte. Sizokufanisa nomphathi wokumaketha ochwepheshe kakhulu ukuze akukhonze.
