PTFE maualuga-vevela ie (PTFE-coated fiberglass) o se faʻasalalauga faʻasalalau faʻapitoa mo tulaga ogaoga: faʻamalo le pefu kasa (sima, otaota otaota, koale koale e oʻo atu i le 260 ° C), faʻamama vai (acid, alkalis, suauʻu), meaʻai / vailaʻau faʻamamaina sterile, ma HEPA faamama potu mama. O luga ole la'au e puipuia ai le pefu ma fa'afaigofie ona fa'amama. Membrane-laminated togi ausia ultra-maualalo emisi.

PTFE maualuga-vevela ie tausia lelei insulation eletise mai -180 °C i 260 °C: voluma resistivity>10¹³ Ω·cm i 200 °C, dielectric tumau mautu i 2.0-2.1. I luga aʻe o le 260 ° C, faʻamaluluina le PTFE, faʻaleagaina i luga aʻe o le 327 ° C, faʻaumatia faʻamaufaʻailoga tumau. I lalo ifo o le 0°C, e fa'aleleia atili le fa'a'ese'esega ae o le fa'alavalava e malepe. Tumau i totonu ole 260°C mo le fa'atinoga fa'atuatuaina.

Fa'auma fa'auma sui fa'aoga i le ie fiberglass a'o le'i fa'apipi'iina le PTFE e taua tele mo le fa'atinoina o ie vevela maualuga o le PTFE. Organosilane so'o fa'apipi'i fa'atūina alalaupapa mole i le va o alava tioata inorganic ma organic PTFE, fa'ateleina le malosi pa'u mai <2 N/cm i le 4-8+ N/cm. O togafitiga talafeagai e faʻaleleia ai foi le faʻafefe o le vevela (260 ° C +), faʻaogaina o le dielectric, ma le faʻamaʻiina o vailaʻau. O ie e le togafitia e tau atu i le delamination, fa'afefeteina, ma le ola puupuu.

Fua lalaga fiberglass - manino, twill, po'o satin - e matua a'afia ai meatotino PTFE maualuga-vevela ie. O le lalaga satin e ofoina atu le malosi sili ona loimata (2-3x manino) ma le fetuutuunai, lelei mo le punou malosi. O lalaga lalaga e maua ai le tulaga sili ona mautu ma le pipii o le pa'u, e fetaui lelei mo le fa'aogaina o mea. Twill faapaleni meatotino uma mo le faaaogaina lautele.

Ufiufi uniformity o le PTFE maualuga-vevela ie e fuafuaina e mea e fa: faʻapipiʻi faʻapipiʻi (tele matolu 0.15-0.35 μm, viscosity, mea mautu), faʻapipiʻi & sintering faagasologa (lau e sili ona lelei mo le tutusa), tulaga lelei substrate (lalaga mamanu, muai togafitiga), ma le siosiomaga gaosiga (20-25 ° C, <60). Fufulu + lau fa'agasologa tu'ufa'atasia fa'apaleni le ulu ma le lamolemole o luga.

O le fa'amamāina lelei ma le tausiga e fa'alautele ai le ola o le ie vevela maualuga o le PTFE. Fa'amama pe a uma ona fa'aoga ma pe'a mālūlū. Fa'aaogā pulumu vaivai, vai fa'afefete, po'o le ava malosi mo pisia. 'Aua ne'i fa'aogaina ni vaila'au malosi/alkali, pitiki, po'o ni u'amea. Lubrication masani suauu silicone faaitiitia ofu. Mulimuli i taiala nei e puipuia ai le faaleagaina o le ufiufi.

PTFE maualuga-vevela ie ma silicone ie e faʻaaoga uma ie fiberglass e fai ma faʻavae ae ese i mea faʻapipiʻi (PTFE resin vs silicone paʻu). O le PTFE e sili atu i le le faʻapipiʻi, faʻaofuofu teteʻe, ma vailaʻau tetee e oʻo atu i le 260°C. Ie silikoni e ofoina atu le sili atu le fetuutuunai, faʻapipiʻi eletise, ma le afi (e oʻo atu i le 230°C). Filifili e fa'atatau i lau fa'amuamua.

PTFE maualuga-vevela ie ofo atu tulaga ese kemikolo tetee, tetee malosi acids, alkalis, solvents organic, ma kasa pala. O lenei tusiga o loʻo faʻamatalaina ana mea faʻasaʻo, tapulaʻa (metala alkali liusua, vailaʻau faʻafefete malosi), ma mea taua e pei o le vevela, faʻatonuga, ma faʻalavelave faʻainisinia.

PTFE impregnation e le gata i ie fiberglass. O lenei tusiga o loʻo faʻaalia ai isi mea e 7 - aramid, carbon fiber, PBI, porous metal, graphite, asbestos (faʻaumatia), ma faʻatumu sima - faʻatasi ai ma a latou faʻagasologa o foliga, lelei, tapulaʻa, ma faʻaoga autu.

O lenei tusiga o loʻo faʻamatalaina pe aisea e avea ai le ie fiberglass e sili ona lelei mo le PTFE ie vevela maualuga. E aofia ai le fa'aogaina o vaila'au e ala i so'o fa'apipi'i silane ma mea taua fa'aletino e pei o le mautu o le vevela, tulaga mautu, ma le fa'a'ele'ele - fa'amautinoa le umi o le fa'atinoga i si'osi'omaga faigata.
