Nylon cov ntxaij lim dej feem ntau haum rau kev lim cov kua aqueous thiab cov tshuaj tsis tshua muaj siab.

Tshawb cov ntaub ntawv hauv-qhov tob ntawm 0.45 micron lim hauv tsab xov xwm no, qhia koj los ntawm cov lus tshwj xeeb los pab koj xaiv qhov kev xav tau rau koj cov kev xav tau:Cov lus qhia tiav rau 0.45 micron lim dej: txhua yam koj xav paub

Hydrophilicity \ / hydrophobicity

PVDF: PVDF yog inheristly hydrophobic

PVDF yog inheristly hydrophobic thiab cov roj hmab dej.

Cov cuab yeej no ua rau PVDF cov koob txia lim tsim rau kev lim cov khoom tsis muaj aqueous thiab cov qauv nrog cov ntsiab lus dej tsawg.

Nylon:

Nylon feem ntau hydrophilic thiab cov khoom pov thawj kev sib txuam rau dej.

Nylon cov lim dej ua tau zoo rau kev lim cov kua aqueous thiab cov qauv nrog cov ntsiab lus dej siab.

Cov tshuaj tiv thaiv muaj protein

PVDF:

PVDF Cov Khoom Siv Limyog pom zoo thaum muaj protein tsawg los yog qhov tseem ceeb.

Lawv feem ntau siv nyob rau hauv cov ntawv thov uas protein rov qab yog qhov kev txhawj xeeb tseem ceeb, xws li tshuaj lom neeg lossis cov qauv biochemical.

Nylon:

Nylon Wyringune tej zaum yuav nthuav tawm cov protein ntau dua cov khoom siv protein ntau dua piv rau PVDF.

PVDF tuaj yeem yog qhov kev xaiv zoo dua rau kev thov cov protein adsorption tsawg kawg nkaus.

Kub tiv thaiv

PVDF: PVDF muaj kev tiv thaiv tshav kub zoo

PVDF zoo haum rau cov txheej txheem kev lim dej ntawm qhov kub thiab txias vim nws cov kub ua kom zoo.

Nws tuaj yeem tiv thaiv ntau yam kub uas tsis muaj kev cuam tshuam cov qauv txheej txheem.

Nylon:

Nylon cov ntaub lim dej kuj muaj cov kub ua haujlwm kuj tseem muaj cov cua sov ua kom zoo, tab sis yuav tsis haum li PVDF rau cov ntawv thov ntawm huab huab cua sov.

Tau sib xyaw nrog cov txheej txheem tshuaj ntsuam

PVDF:

PVDF Cov Khoom Siv Limyog feem ntau siv hauv kev ntsuas kev ntsuas xws li HPLC.

Lawv nyiam vim yog lawv cov qib qis dua thiab kev sib cav sib xyaw nrog ntau txoj kev ntsuas.

Nylon:

Nylon cov tshuaj lom lim lim yog tsim nyog rau kev lim dej dav dav.

Tej zaum lawv yuav tsis yog qhov kev xaiv zoo tshaj plaws rau qee yam kev qhia paub tseeb tias yuav tsum muaj cov qib tshuaj ntxiv, tab sis lawv tseem siv dav hauv chav kuaj ib txwm muaj.

4 Qhov laj thawj xaiv PvDF

Tshuaj sib xyaw ua ke:PVDF (polyvinylidene fluoride) cov ntxaij lim dej muaj cov tshuaj lom neeg, suav nrog cov qauv, thiab cov kuab tshuaj thiab cov kuab tshuaj hauv kev kuaj thiab kuaj cov ntawv thov.

Siab Purity:PVDF cov ntxaij lim xwv yog paub txog lawv cov protein cov protein tsawg, ua kom zoo tshaj plaws rau cov ntawv thov, xws li kev tshawb xyuas cov protein, tshuaj xyuas tshuaj, thiab biotechnology.

Thermal Stability: PVDF LimKev nthuav qhia cov hluav taws xob zoo heev, kev tswj hwm lawv txoj kev ncaj ncees thiab kev ua tau zoo dhau qhov dav kub ntau. Qhov no ua rau lawv haum rau cov ntawv thov uas yuav tsum tau ua kom tsis muaj menyuam lossis autoclaving, kom ntseeg tau cov txiaj ntsig txawm tias muaj mob heev.

Neeg kho tshuab zog:PVDF cov ntxaij lim dej yog inherently muaj zog thiab ruaj, nrog lub zog siab tensile thiab kev tawm tsam kom ntuag. Qhov no ua rau lawv haum rau kev lim dej ntawm kev ua kom nruj lossis kev pheej hmoo ntawm cov lim lim tsis muaj kev pheej hmoo los yog tsis ua tiav, kom ua tiav cov txheej txheem.

Hauv cov ntsiab lus, kev xaiv ntawm PVDF thiabNylon Wyringune limNyob ntawm cov kev cai tshwj xeeb ntawm cov txheej txheem pom, muaj xws li cov kuab tshuaj, qhov kev xav tau cov protein rov qab, thiab kev sib raug zoo nrog cov txheej txheem analytical. Rau kev ua raws li kev ua raws li kev ua tau zoo, ib txwm xa mus rau cov chaw tsim khoom pom zoo thiab xav txog cov khoom tshwj xeeb ntawm txhua cov khoom.
