Thaum tshawb nrhiav cov ntaub zoo tshaj plaws rau cov plua plav lim dej, ob cov ntaub ntawv tau txais txiaj ntsig zoo rau lawv qhov kev ua tau zoo tshwj xeeb: PTFE (Polytetrafluoroethylene) thiab nws daim ntawv nthuav dav, ePTFE (Expanded Polytetrafluoroethylene). Cov khoom siv hluavtaws no, paub txog lawv cov khoom siv tshuaj lom neeg thiab lub cev, tau rov txhais cov plua plav pom hauv qhov chaw xav tau, muab cov txiaj ntsig zoo uas ua rau lawv sib nrug ntawm cov ntaub ib txwm muaj xws li paj rwb, polyester, lossis txawm tias cov ntaub ntawv HEPA txheem.
PTFE, feem ntau raug xa mus los ntawm nws lub npe Teflon, yog fluoropolymer ua kev zoo siab rau nws cov khoom tsis-stick, tshuaj tiv thaiv, thiab kev ua siab ntev. Hauv nws daim ntawv nyoos, PTFE yog cov khoom siv ntom ntom, tab sis thaum tsim khoom rau hauv cov ntaub lim dej, nws tsim ib qho chaw du, tsis tshua muaj kev sib txhuam uas ua rau cov plua plav, kua, thiab cov khoom paug. Qhov no tsis yog-nplaum zoo yog qhov tseem ceeb rau cov plua plav pom: tsis zoo li cov ntaub ntxeem tau uas ntxiab cov khoom sib sib zog nqus hauv lawv cov fibers (ua rau txhaws),PTFE limtso cai rau cov plua plav mus rau ntawm qhov chaw, ua kom yooj yim los ntxuav lossis co tawm. Qhov no "nto loading" feature ua kom muaj huab cua zoo sib xws nyob rau lub sijhawm, qhov txiaj ntsig tseem ceeb hauv cov chaw muaj plua plav siab xws li chaw tsim kho lossis chaw tsim khoom.
ePTFE, tsim los ntawm stretching PTFE los tsim ib tug ntxeem tau qauv, yuav siv sij hawm pom kev ua tau zoo mus rau qib tom ntej. Cov txheej txheem nthuav dav tsim ib lub network ntawm microscopically me pores (feem ntau ntawm 0.1 thiab 10 microns) thaum tuav PTFE cov khoom siv hauv paus. Cov pores no ua raws li lub sieve meej: lawv thaiv cov plua plav-xws li cov khoom me me (PM2.5) thiab txawm tias cov micron me me-thaum tso cai rau huab cua los ntawm qhov tsis muaj kev cuam tshuam. ePTFE's porosity yog customizable heev, ua rau nws haum rau daim ntaub ntawv xws li los ntawm tej huab cua purifiers (filtering tsiaj dander thiab paj ntoos) mus rau industrial cleanrooms (capturing ultrafine manufacturing byproducts).
Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm PTFE thiab ePTFE yog lawv cov kav ntev thiab ua haujlwm rau cov xwm txheej hnyav. Tsis zoo li paj rwb lossis polyester, uas tuaj yeem degrade thaum raug tshuaj lom neeg, ya raws, lossis kub, PTFE thiab ePTFE yog inert rau feem ntau cov khoom, nrog rau cov kua qaub thiab cov kuab tshuaj. Lawv tuaj yeem tiv taus qhov kub ntawm -200 ° C txog 260 ° C (-328 ° F txog 500 ° F), ua rau lawv zoo tagnrho rau siv rau hauv qhov cub, cua tshuab, lossis qhov chaw sab nraum zoov uas cov ntxaij lim dej raug huab cua huab cua. Qhov no resilience txhais mus rau lub neej ntev-PTFE thiab ePTFE cov ntxaij lim dej tuaj yeem nyob rau lub hlis lossis ntau xyoo nrog kev saib xyuas kom zoo, ua haujlwm zoo dua li cov ntaub ntawv lossis cov lim dej hluavtaws.
Lwm qhov zoo dua yog lawv cov kev tu ncua tsawg. Ua tsaug rau PTFE tsis-stick nto, hmoov av tsis ua raws li cov khoom siv lim. Feem ntau, tsuas yog co lub lim los yog siv cov cua compressed txaus kom tshem tawm cov plua plav, rov ua kom nws ua haujlwm zoo. Qhov no reusability tsis tsuas yog txo cov pov tseg tab sis kuj txo cov nqi mus sij hawm ntev piv rau ib leeg-siv lim. Piv txwv li, hauv cov tshuab nqus tsev ntxhua khaub ncaws, ePTFE cov ntxaij lim dej tuaj yeem ntxuav tau ntau lub sijhawm ua ntej xav tau kev hloov pauv, txo qis ntawm cov nuj nqis ua haujlwm.
Thaum piv rau HEPA cov ntxaij lim dej-ntev txiav txim siab tus qauv kub rau kev pom zoo-ePTFE tuav nws tus kheej. Thaum HEPA cov ntxaij lim dej ntes 99.97% ntawm 0.3-micron hais, cov ntxaij lim dej zoo ePTFE tuaj yeem ua tiav qib zoo sib xws lossis ntau dua. Tsis tas li ntawd, ePTFE lub airflow zoo dua (vim nws cov qauv pore optimized) txo qhov kev nyuaj siab ntawm cov kiv cua, ua rau nws muaj zog ntau dua li HEPA hauv ntau daim ntawv thov.
Hauv kev xaus, PTFE thiab ePTFE sawv tawm raws li cov ntaub tshwj xeeb rau cov plua plav lim. Lawv qhov sib xyaw ua ke ntawm cov tshuaj tsis haum, qhov kub thiab txias, qhov porosity customizable, thiab reusability ua rau lawv muaj ntau yam txaus rau kev siv txhua hnub thiab kev lag luam. Seb nyob rau hauv daim ntawv ntawm ib tug tsis-stick PTFE nto rau hnyav-duty plua plav sau los yog nthuav ePTFE membrane rau ultra-fine particle filtration, cov ntaub ntawv no muaj ib tug txhim khu kev qha, ntev-ntev tshuaj kom huab cua tsis muaj plua plav thiab paug. Rau cov neeg nrhiav kev lim dej uas sib npaug ntawm kev ua haujlwm, ua haujlwm ntev, thiab kev ua haujlwm tau zoo, PTFE thiab ePTFE yog qhov tsis ntseeg ntawm cov kev xaiv zoo tshaj plaws.
