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.

PTFE maualuga-vevela ie (PTFE-coated fiberglass) e lelei mo fusi conveyor meaai ona o lona 260 ° C vevela tetee, -70 ° C malulu fetuutuunai, non-stick luga, ma le tausisia FDA. Fa'aoga autu: ogaumu faifalaoa (masi, falaoa, pizza), fe'avea'i mea'ai falai, laina lole lole, alavai fa'a'aisa, fa'amaufa'ailoga vevela, ma le afifiina. Faʻaitiitia taimi faʻaumatia ma faʻamamā.

Calendering - faʻapipiʻiina le ie faʻapipiʻi PTFE i le va o faʻata faʻavela i le 360-380 ° C - e matua suia ai le morphology o luga, faʻasaʻo meatotino, le mafai, ma le faʻaaogaina o masini. E faʻaitiitia ai le talatala mai le Ra 0.5-1.0 μm i le <0.05 μm, faʻamaufaʻailoga pine, faʻaleleia le faʻaogaina o le ofuina, ae faʻaitiitia le malosi o loimata ma le fetuutuunai. E taua mo le faʻasaʻoina o laina ma le faʻamalo eletise.

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.

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.
