Tshawb Nrhiav Kev Sib Raug Zoo Ntawm Qhov Hnyav Molecular, Viscosity, Cov Khoom Khoom, thiab Qhov Zoo ntawm PolyDADMAC

PolyDADMAC (tseem hu ua "polydiallyl dimethyl ammonium chloride") yog ib qho cationic polymer siv rau hauv cov txheej txheem kho dej. Nws muaj nqis rau nws cov flocculation zoo thiab coagulant teebmeem. Ua tus neeg muab khoom thiab tus faib khoom ntawm cov tshuaj kho dej, nws yog ib qho tseem ceeb kom nkag siab txog kev sib raug zoo ntawm qhov hnyav molecular, viscosity thiab cov khoom khov ntawm PolyDADMAC thiab cov khoom zoo. Hauv tsab xov xwm no, peb yuav tshawb nrhiav kev sib raug zoo ntawm cov cim no thiab yuav ua li cas xaiv cov khoom zoo uas haum rau koj.

Qhov hnyav molecular, viscosity thiab cov khoom khov ntawm PolyDADMAC yog cov yam ntxwv tseem ceeb uas cuam tshuam rau nws cov nyhuv. Lawv muaj feem cuam tshuam. Cov hauv qab no yog cov lus piav qhia ntxaws txog lawv thiab cov lus piav qhia ntxaws txog lawv txoj kev sib raug zoo:

1. Kev Sib Raug Zoo

Qhov hnyav molecular yog hais txog qhov ntev nruab nrab ntawm PolyDADMAC polymer saw.

Feem ntau qhov hnyav ntawm cov molecular siab dua txhais tau tias cov saw polymer ntev dua, uas tuaj yeem txhim kho lub peev xwm ntawm PolyDADMAC flocculation. Thiab qhov hnyav ntawm cov molecular siab dua feem ntau muab qee qhov kev sib txuas, uas tso cai rau cov khoom me me hauv dej txuas ua ke. Nws tuaj yeem txhim kho cov teebmeem kev kho dej.

Txawm li cas los xij, qhov hnyav molecular siab dhau kuj tuaj yeem ua rau muaj viscosity ntau dhau, uas cuam tshuam rau kev ua haujlwm.

Qhov hnyav molecular yog qhov qhia tseem ceeb ntawm PDADMAC zoo vim nws cuam tshuam ncaj qha rau nws cov txiaj ntsig ntawm daim ntawv thov.

Qhov hnyav ntawm PDADMAC feem ntau yog txij li 50,000 txog 700,000Da, thiab cov khoom uas muaj qhov hnyav molecular siab heev yuav tsum siab tshaj plaws ntawm 3,000,000Da.

2. Qhov nplaum

Viscosity yog hais txog qhov tsis kam ntawm PolyDADMAC kua kom ntws.

Feem ntau qhov viscosity yog 80-12,000mPa.s, thiab kuj tseem muaj cov PolyDADMAC siab-viscosity nrog viscosity ntau dua 100,000. Viscosity muaj feem cuam tshuam nrog qhov hnyav molecular, thiab qhov hnyav molecular siab dua ua rau muaj viscosity siab dua. Thiab viscosity cuam tshuam rau solubility thiab dispersibility ntawm PDADMAC, nrog rau nws cov kev ua haujlwm hauv daim ntawv thov. Yog tias viscosity siab dhau, qhov viscosity siab yuav ua rau qee qhov teeb meem kev ua haujlwm (hloov thiab diluting, thiab lwm yam) Viscosity yog ib qho tseem ceeb rau kev ntsuas qhov zoo ntawm PDADMAC vim nws cuam tshuam nws qhov hnyav molecular thiab kev ua haujlwm daim ntawv thov., thaum qis-viscosity PolyDADMAC muaj cov kua dej zoo thiab yooj yim rau twj.

3. Cov ntsiab lus khov kho

Cov ntsiab lus khov kho yog hais txog feem pua ​​​​​​ntawm qhov hnyav ntawm polymer hauv PolyDADMAC kua.

Cov khoom khov uas muaj ntau txhais tau tias tus nqi khaws cia thiab thauj khoom yuav txo qis. Txawm li cas los xij, yog tias cov khoom uas muaj qhov hnyav molecular siab heev raug npaj ua 40% kua, nws tsis tuaj yeem nchuav tawm ntawm lub thoob.

Cov ntsiab lus khov kho ntawm PolyDADMAC yog 10% lossis 50%, uas yog, qhov sib piv ntawm cov tshuaj muaj txiaj ntsig zoo hauv cov tshuaj

Feem ntau, cov ntsiab lus khov kho ntawm PolyDADMAC uas peb muag yog li ntawm 40%. Peb kuj muaj lwm cov lus qhia txog cov ntsiab lus khov kho.

Koj tuaj yeem tshawb xyuas qhovCov lus piav qhia txog cov khoom ntawm PolyDADMACrau cov lus qhia tshwj xeeb thiab cov ntsuas qhia ntxaws ntawm PolyDADMAC.

Txoj kev sib raug zoo ntawm lawv:

Qhov hnyav molecular thiab viscosity:

Rau cov khoom khov zoo ib yam, qhov hnyav molecular siab dua, qhov viscosity ntau dua.

Qhov loj dua qhov hnyav molecular, qhov siab dua qhov viscosity.

Cov ntsiab lus khoom thiab viscosity:

Rau tib lub molecular hnyav, qhov siab dua cov khoom khov, qhov ntau dua qhov viscosity.

Qhov hnyav molecular, cov ntsiab lus khoom, thiab kev ua tau zoo:

Ntawm qee cov ntsiab lus khov kho, qhov hnyav molecular siab dua, qhov zoo dua qhov cuam tshuam, tab sis viscosity yuav nce ntxiv.

Yuav ua li cas xaiv PolyDADMAC uas haum rau koj

Tsim nyog viscosity: xyuas kom meej fluidity, yooj yim solubility, thiab zoo flocculation kev ua tau zoo.

Yog tias koj xav tau nrhiav tus neeg muag khoom tshiab los yuav PolyDADMAC, ces ua ntej koj yuav tsum txiav txim siab seb koj cov dej zoo li cas kom koj tus neeg muag khoom tuaj yeem pab koj xaiv tus qauv zoo dua.
