PTFE maualuga-malosi ie vevela maualuga o se tuʻufaʻatasia o fiberglass maualuga-tenacity ma PTFE coating. Fa'aoga autu e fa'asolo atu i le fa'auluina o mea tau pisinisi (fa'ameamea mea'ai, fa'agogo ie, felauaiga PCB), puipuiga fa'apipi'i (ufi fa'amaufa'ailoga vevela, talipupuni fa'afefeteina), fa'apalapala ma lomitusi vevela (fasi pa'u, lamination PV), insulation eletise (lines slot motor, afifi uaea), membranes fausaga (fale faletaalo, 30+ tausaga le ola), (expanning anti-corrosion so'otaga), vailaʻau anti-corrosion soʻotaga. palanikeke), ma faʻaoga faʻapitoa (oti leisa, lolomi 3D).

Faamago o se laasaga taua i le PTFE maualuga-vevela ie gaosiga. O fa'aletonu masani e aofia ai: ta'e (vave tele le fa'agogo, pa'u i luga o le pa'u), felauaiga fa'apipi'i (fa'agai'i i luga o mea i luga, vaivai le sootaga i totonu), pine/pa'u (ea po'o le ausa), pa'epa'e ma penisina (surfactant migration po'o le fusu'a atoatoa), samasama/coking (sova o mea fa'aopoopo), delamination (pepa fa'afefeteina), sili atu le fa'ama'i (srinkasion), fa'afefeteina (fa'ama'i o le fa'afugaga), fa'afefeteina (fa'ama'i fa'ama'i), fa'ama'i (srinkasion) sili atu. fa'aiti'itia), matutu luga ae susū totonu (malei pa'u susu), ma pito mafiafia (aafiaga mama-kofe). O vaifofo e aofia ai fa'amatalaga fa'amamago fa'atonu, fa'asa'o lelei o le ea, ma le fa'agasologa muamua o mea'ai.

PTFE emulsion impregnation o ie fiberglass e manaʻomia ai ausilali eseese e ausia le ufiufi toniga, pipii malosi, ma luga ole pona. O mea fa'aopoopo autu e aofia ai: fa'asusu susū (fa'aitiitia le vevesi i luga o le fogaeleele, fa'aleleia atili le tu'uina atu), mafiafia (pulea le viscosity ma le mamafa o le ufiufi), pH regulators (fa'amautu le emulsion i le pH 9-10), silane so'otaga fa'apipi'i (fa'aleleia le pipii i tioata), fesoasoani e fai ata tifaga (PFA/FEP mo le sintering), fa'atumu galuega (tete'e fa'aofuofu, conductivity), ma le fa'aogaina o mea'ai (tete'e fa'aofuofu, fa'auluuluga), ma fa'auluuluga. fa'amago). Filifiliga e faʻalagolago i mea e manaʻomia ma faʻatinoga.

Ie fa'afiufimata fa'alautele (ie vulu fa'atele) e matua'i 'ese'ese mai ie fa'aigoa fa'aigoa i le fausaga o vulu. E ala i le maualuga-omiomi togafitiga vaalele ea, o filaments tioata faifai pea e tuueseeseina, crimped, ma fluffed i voluminous, vulu pei o le cotton. O le mea lea e maua ai le ie mafiafia, malūlū ma le fa'amama fa'amalo maualuga (pu'eina o le ea), sili atu le fa'amalieina, sili atu le lelei o le fa'amama, ma fa'aleleia le tete'e o loimata/fele - i le tau o le malosi teisi la'ititi. Fa'aoga mo gaskets vevela maualuga, afifi paipa, taga faamama, ma fa'amaufa'ailoga ogaumu.

O le mama o mea mata o le faavae o le PTFE maualuga-vevela ie faatinoga. Emulsion PTFE maualuga-mama (leai ni u'amea u'amea, leai ni toega maualalo-molecular-mamafa) fa'amautinoaina le vevela (leai se samasama e o'o atu i le 260 ° C), fa'amautu e leai se la'au, ma le malosi dielectric maualuga. Mo fiberglass, E-glass e leai se alkali (Na₂O <0.8%) e faʻatumauina le malosi ma le faʻafefe i le maualuga o le vevela; tioata feololo/maualuga-alkali e mafua ai le fa'aleagaina. O le ave'esea atoatoa o mea lalaga e fa'apipi'iina e puipuia ai le fa'akalapona ma le fa'apala. O le mama e aafia sa'o ai le ola tautua, le tausisia o mea'ai, ma le faatuatuaina o le eletise.

Fa'amamago sa'o o le ie fiberglass e taua tele mo le fa'apipi'iina o le PTFE mulimuli ane, fa'amago resini, po'o le lamination. Tolu togafitiga autu: faʻamama le susu ile 105-120 ° C (10-30 min e faʻatatau i le mamafa), atuaxing / faʻamamaina vevela ile 300-450 ° C (LOI <0.1%, aloese> 500 ° C), ma le faʻamafanafanaina i le 60-100 ° C aʻo leʻi faʻapipiʻiina. Pulea le tutusa o le vevela o le ogaumu (± 5°C), fa'amama fa'amalosi, ma puipui ie e fa'amama le silane i lalo ole 110°C. Teu ie mamago i taga fa'amaufa'ailoga po'o potu mago (<30°C, <40% RH).

PTFE maualuga-vevela ie (PTFE-coated fiberglass) e toetoe lava a chemically inert, ae o nisi o mea e mafua ai le pala i lalo o tulaga patino. O osofa'iga tu'usa'o a le PTFE e tupu ile u'amea alkali liusu (sodium, potassium), vaila'au fa'afefete malosi (F₂, ClF₃) i le vevela maualuga, ma le alkalis malosi liusua i luga ole 300°C. O le pala e le tuusa'o e tupu pe a o'o i le fa'aletonu o le fa'alavalava ma osofa'ia ai le mea'ai fiberglass. Mo le tele o auaunaga fa'ama'i, fa'aaoga ata PTFE mama e aunoa ma se fiberglass.

PTFE maualuga-vevela ie (PTFE-coated fiberglass) e sili ona lelei tete'e te'i vevela i totonu o lona tulaga masani faagaoioia o -70°C i le 260°C. E mafai ona fa'apalepale i le uila vave o le vevela, fa'ata'ita'iga, alu mai le -50°C pusaaisa i le 260°C lomitusi vevela. O togi maualuga e o'o lava i le maalili fa'afuase'i mai le 260°C ile 10°C vai. Ae ui i lea, fa'ate'ia mea mai le vevela i luga atu o le 300°C (latalata i le PTFE's 327°C melting point) o le a mafua ai ona ta'e vave ma delamination. O le fiberglass substrate e maua ai le tulaga mautu; o le ufiufi PTFE o le mea faʻatapulaʻa.

PTFE maualuga-vevela ie o loʻo faʻaaogaina lautele i le alamanuia vailaʻau mo le fitu talosaga autu: flange gaskets ma paipa linings (tetee malosi acids / alkalis), reactor ma tane linings (taofia le pala uʻamea, faigofie faamamaina), taga faamama mo kesi fue corrosive (e oo atu i le 260 ° C), anti-corrosion faʻalauteleina sooga mo ducts faʻasaʻo, faʻapipiʻi faʻapipiʻi faʻapipiʻi mo ducts faʻapipiʻi, faʻapipiʻi faʻapipiʻi faʻapipiʻiina. ma afifi fa'amalama eletise/vevela. FDA ma UL togi avanoa.

PTFE maualuga-vevela ie (PTFE-coated fiberglass) ofoina atu tulaga lelei autu e fa e pei o se lining anti-corrosion: chemical inertness (tetee aqua regia, malosi alkalis, solvents), lautele o le vevela (-70 ° C i le 260 ° C faifai pea, 350 ° C tumutumu), dimensional mautu (<0.5% faʻamama luga), ma non-stick elongation, ma non-stick elongation. Fa'aoga i paipa vaila'au, olo desulfurization, tane piki, ma mea'ai/faletalavai. E maua togi FDA.
