PTFE maualuga-vevela ie e taua i le alamanuia interlining ofu. Fa'aoga autu: fusipa'u fe'avea'i e leai se gataaga mo masini fa'apipi'i faifaipea (e taofia le pipii o le pipii vevela liusuavai, fe'avea'i e aunoa ma le maanuminumi), ufiufi e le o la'au ma ie fa'apipi'i mo lomi vevela mafolafola (puipuia platens mai fa'ama'i pipi'i), fusi fa'amomoli mo togi fa'apipi'i/uila fa'afuifu laina (tausia fa'amago fa'apipi'i togitogi fa'apipi'i i le taimi e fa'amamago ai togitogi fa'apipi'i), ma fa'amamago fa'amau fa'apipi'i fa'amago ufi. O le mafiafia e amata mai i le 0.13mm (pepa mama) e o'o i le 0.55mm (pepa fe'avea'i mamafa).

E maua le ie PTFE Anti-static e ala i auala autu e lua: ufiufi doping (faafefiloi conductive fillers e pei o le carbon uliuli i le PTFE emulsion, faia o se fesootaiga percolation i le ogaoga concentration) ma substrate lalagaina (embedding conductive filo i ie fiberglass). O lo'o fa'atonutonuina le fa'asao o luga ile 10⁵–10⁹ Ω. O le fa'avae: fa'atupu se ala fa'aa'oa'oga e fa'amama fa'ato'a fa'ato'a fa'afuase'i, e taofia ai le fa'aputuina mata'utia. E fa'atulafonoina le fa'avae mo galuega lelei.

PTFE maualuga-vevela ie (PTFE-coated fiberglass) e ofoina atu le tetee faʻamaʻi faʻapitoa, faʻasalaina acids faʻapitoa (e aofia ai le aqua regia), alkalis malosi (i le vevela o le potu), solvents organic, ma vailaʻau faʻamaʻi. Tuusaunoaga: u'amea alkali liusua ma fa'afefiloi halogen maualuga-vevela osofa'i PTFE. O le fa'aleagaina o le ufiufi e fa'aalia ai le fiberglass i le hydrofluoric acid ma le vevela vevela. O le vevela i luga aʻe o le 260°C e faʻaitiitia ai le teteʻe. Mo le tele o siosiomaga kemisi, PTFE ie tumau maualuga mautu ma faatuatuaina.

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'atonutonuina, fa'asa'o lelei o le ea, ma le fa'agasologa muamua o mea'ai.

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, 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.

mama mea mata o le faavae o 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 carbonization ma le delamination. O le mama e aafia sa'o ai le ola tautua, le tausisia o mea'ai, ma le faatuatuaina o le eletise.

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 PTFE faʻapipiʻi 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 vevela vaega (-70°C i le 260°C faaauau pea, 350°C tumutumu), dimensional mautu (<0.5% elongation luga), ma non-stick elongation, ma non-stick elongation). Fa'aoga i paipa vaila'au, olo fa'asufurization, tane piki, ma mea'ai/faletalavai. E maua togi FDA.
