PTFE Membrane Lim Cov ntsiab lus

PTFE membrane lim muaj cov tshuaj zoo sib xws, yog li ntawd lawv kuj tau siv rau kev pom cov kuab tshuaj thiab cov kua qaub, uas lwm cov lim dej tsis muaj zog.Vim lawv cov yam ntxwv hydrophobic, lawv yuav tsum tau prewetted nrog ethanol los yog methanol ua ntej pom ntawm aqueous xov xwm.

Taw qhia

Membrane lim los yog "membranes" yog cov yas yas microporous nrog cov kev ntsuas qhov pore loj.Kuj hu ua screen, sieve los yog microporous lim, membranes khaws cov khoom los yog cov kab mob loj dua lawv qhov pore loj feem ntau los ntawm qhov chaw ntes.Qee qhov me me dua li qhov pore loj tau teev tseg tuaj yeem khaws cia los ntawm lwm cov txheej txheem.PTFE membranes yog tsim los ntawm peb txheej txheem sib txawv.Mixed Cellulose Esters, Cellulose Acetate, thiab Nylon yog thim rov qab theem hnyav cam khwb cia daim nyias nyias, qhov twg tswj evaporation los yog tshem tawm cov complex solvent system tsim cov porous qauv.Ob qho tib si hydrophilic thiab hydrophobic PTFE yog tsim los ntawm cov txheej txheem patented uas cov membranes stretched biaxially los tsim cov qauv ntxeem tau.

Kev ua tau zoo ntawm PTFE Membranes

• Muaj zog: PTFE daim nyias nyias yog saib xyuas rau ob qho tib si tawg (ntev) thiab tensile (sab tom) lub zog.Supported Acetate thiab Nylon yog lub zog rov qab theem membranes muaj.
• Chemically thiab biologically huv si: Raws li ib feem ntawm cov kev pab cuam zoo, tsuas yog cov purity siab reagents thiab raw cov ntaub ntawv yog siv los tsim PTFE membranes.Thaum cam khwb cia, cov membranes yog lis nyob rau hauv ib chav kawm ntawv 1000 huv si kom txo ambient paug.Thaum qee cov membranes xav tau ib qho me me (0.1-3 qhov hnyav %) ntawm cov dej ntub dej, Cellulose acetate muaj cov dej qis tshaj plaws (0.1 qhov hnyav %) thiab Nylon, inherently hydrophilic, tsis muaj ntxiv wetting agents lossis surfactants.
• Nyias daim nyias nyias nrog siab porosity: Cov ntaub nyias nyias nyias (feem ntau yog 150 µm) nrog cov porosity siab (kwv yees li 80%) muab cov pa roj thiab cov kua dej ntau hauv ib cheeb tsam.High porosity kuj muab qhov chaw siab rau adsorption lossis khi.
• Thermostable: Txhua PTFE daim nyias nyias tuaj yeem ua kom tsis muaj menyuam los ntawm autoclaving.Kev khiav hauj lwm kub txog li 180 ° C tuaj yeem ua tiav nyob ntawm daim nyias nyias polymer .PTFE daim nyias nyias muaj qhov tsawg tsawg ntawm qhov kub siab.

Phau ntawv ceev rau xaiv Membrane Lim

• Txiav txim siab seb cov kua lossis roj yuav raug lim.
• Xyuas seb cov membranes twg yog cov tshuaj sib haum.
• Txiav txim siab qhov pore loj tshaj plaws uas yuav tsum tau ua kom ua tiav cov txiaj ntsig koj xav tau.
• Tshawb xyuas cov txheej txheem membrane rau cov txheej txheem txawv txav uas yuav txwv tsis pub koj xaiv ntawm daim nyias nyias (xws li kub).
