Tshawb nrhiav PolyDADMAC

Tshawb nrhiav kev sib raug zoo ntawm Molecular Nyhav, Viscosity, Khoom Khoom, thiab Zoo ntawm PolyDADMAC

PolyDADMAC (tseem hu ua "polydialyl dimethyl ammonium chloride") yog cationic polymer siv hauv kev kho dej. Nws muaj nuj nqis rau nws qhov zoo flocculation thiab coagulant cuam tshuam. Raws li tus neeg xa khoom thiab xa tawm 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 ntsiab lus ntawm PolyDADMAC thiab cov khoom zoo. Hauv tsab xov xwm no, peb yuav tshawb nrhiav qhov sib txheeb ntawm cov ntsuas no thiab yuav ua li cas xaiv cov khoom zoo uas tsim nyog rau koj.

Qhov hnyav molecular, viscosity thiab cov ntsiab lus ntawm PolyDADMAC yog qhov tseem ceeb uas cuam tshuam rau nws cov nyhuv. Lawv muaj kev sib txheeb. Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm lawv thiab cov lus piav qhia ntxaws ntawm lawv txoj kev sib raug zoo:

1. Kev sib raug zoo

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

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

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

Molecular hnyav yog ib qho tseem ceeb qhia ntawm PDADMAC zoo vim hais tias nws ncaj qha cuam tshuam nws daim ntawv thov nyhuv.

PDADMAC molecular luj feem ntau yog li ntawm 50,000 txog 700,000Da, thiab cov khoom uas muaj ultra-siab molecular hnyav yuav tsum max tawm ntawm 3,000,000Da.

2. Viscosity

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

Feem ntau cov viscosity yog 80-12,000mPa.s, thiab tseem muaj cov viscosity siab PolyDADMAC nrog viscosity ntau dua 100,000. Viscosity yog ze ze rau qhov hnyav molecular, thiab siab dua molecular hnyav ua rau muaj viscosity ntau dua. Thiab viscosity cuam tshuam rau solubility thiab dispersibility ntawm PDADMAC, nrog rau nws cov kev ua haujlwm hauv kev siv. Yog tias qhov viscosity siab dhau lawm, qhov viscosity siab yuav ua rau qee qhov kev ua haujlwm nyuaj (hloov thiab diluting, thiab lwm yam) Viscosity yog qhov tseem ceeb rau kev ntsuas qhov zoo ntawm PDADMAC vim nws qhia txog nws qhov hnyav molecular thiab daim ntawv thov kev ua haujlwm.

3. Cov ntsiab lus ruaj khov

Cov ntsiab lus khoom yog hais txog qhov hnyav feem pua ​​​​ntawm cov polymer hauv cov tshuaj PolyDADMAC.

Cov ntsiab lus siab txhais tau tias txo tus nqi cia thiab thauj khoom. Txawm li cas los xij, yog tias ib yam khoom uas muaj qhov hnyav molecular hnyav tau npaj raws li 40% kev daws, nws tsis tuaj yeem nchuav tawm ntawm lub nruas.

Cov ntsiab lus ntawm PolyDADMAC yog 10% lossis 50%, uas yog, qhov feem pua ​​​​ntawm cov tshuaj muaj txiaj ntsig zoo hauv cov tshuaj.

Feem ntau, cov ntsiab lus ntawm PolyDADMAC peb muag yog li 40%. Peb kuj muaj lwm yam khoom specifications.

Koj tuaj yeem tshawb xyuas qhovCov ncauj lus kom ntxaws khoom piav qhia ntawm PolyDADMACrau cov kev qhia tshwj xeeb thiab cov ncauj lus kom ntxaws ntawm PolyDADMAC.

Kev sib raug zoo ntawm lawv:

Molecular hnyav thiab viscosity:

Rau tib cov ntsiab lus, qhov siab dua qhov hnyav molecular, qhov ntau dua qhov viscosity.

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

Khoom ntsiab lus thiab viscosity:

Rau tib qhov hnyav molecular, qhov siab dua cov ntsiab lus, qhov viscosity ntau dua.

Molecular hnyav, cov ntsiab lus, thiab kev ua haujlwm:

Ntawm cov ntsiab lus ntawm cov khoom, qhov siab dua qhov hnyav molecular, cov nyhuv zoo dua, tab sis cov viscosity yuav nce.

Yuav ua li cas xaiv PolyDADMAC uas haum rau koj

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