PTFE maualuga-vevela ie tao tao fala e ofoina atu le fa tulaga lelei: e le o ni laau (leai se suauu po o se falaoamata e manaʻomia, maʻaleʻale pastries tatala mama), lautele vevela vaega (-70 ° C i le 260 ° C, saogalemu mo le ogaumu i le pusaaisa), toe faʻaaogaina (afe o taamilosaga, faigofie ona mama), ma e oʻo lava i le vevela (e taofia le mu, paleni enaena). E fa'amalieina le FDA i mea'ai, e sili atu nai lo pepa pa'u ma sili atu le fala silikoni ma sili atu le fa'afefe o le vevela ma le fa'alelei o le lau.

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 masini vevela mafolafola (puipuia platens mai le fa'apipi'i pipi'i), fusi fe'avea'i mo togi fa'apipi'i/uila fa'afuifu laina (tausia fa'amau fa'apipi'i fa'amau togitogi i le taimi e fa'amamago ai le fa'amago fa'apipi'i ufiufi i le taimi e fa'amamago ai. O le mafiafia e amata mai i le 0.13mm (pepa mama) e o'o i le 0.55mm (pepa fe'avea'i mamafa).

Fiberglass ie vevela shrinkage o le mafuaaga autu o le PTFE lipine dimensional le mautu. I le PTFE sintering vevela (360-400 ° C), fa'asa'oloto lalaga mamafa totoe. Afai e le taofiofia, e fa'a'e'e le ie; afai e taofiofia, o lo'o lokaina le fa'amamafa natia i totonu, e mafua ai ona fa'aitiitiga mulimuli ane a'o fa'amalo fa'apipi'i (150-200°C) ma fa'avevela fa'aaoga. Fofo: faʻaaoga muamua-vevela-set fiberglass faʻatasi ma le <0.5% faʻaitiitia ile 400°C, faʻaumatia faʻamaʻi totoe aʻo leʻi faʻapipiʻiina.

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.

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 ole laiga, fa'aleleia le ulu), mafiafia (pulea le viscosity ma le mamafa o le ufiufi), fa'atonu pH (fa'amautu le emulsion i le pH 9-10), so'o fa'apipi'i silane (fa'aleleia le pipii i le tioata), fesoasoani e fai ata tifaga (PFA/FEP mo le sintering), fa'atumu galuega (tete'e fa'aofuofu, fa'auluuluga), ma fa'auluuluga (fa'aofuofu fa'aofuofu), fa'auluuluga, ma fa'auluulu. 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, filaments tioata faifai pea e tuueseeseina, crimped, ma fluffed i voluminous, vulu pei o le cotton. Ole mea lea e fa'atupu ai le ie mafiafia, malūlū fa'atasi ai ma le fa'a'ese'esega fa'avevela sili atu (fa'amauina o le ea), sili atu le fa'amalieina, maualuga le fa'amamaina lelei, ma fa'aleleia le tete'e ma loimata/fa'alelei - i le tau o le malosi teisi la'ititi. Fa'aoga mo gaskets vevela maualuga, afifi paipa, taga faamama, ma fa'amaufa'ailoga ogaumu.

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 liusua (sodium, potassium), fa'amalama fa'afefete malosi (F₂, ClF₃) i le maualuga o le vevela, 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 le mea fa'apipi'i 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, o le faateʻia o mea mai le vevela i luga aʻe o le 300 ° C (latalata i le PTFE's 327 ° C melting point) o le a mafua ai ona taʻe 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 e lautele faaaogaina i le alamanuia vailaau mo talosaga autu e fitu: flange gaskets ma paipa linings (tetee malosi acids/alkalis), reactor ma tane linings (puipuia uamea pala, faamama mama), taga faamama mo kesi fue corrosive (e oo atu i le 260°C), anti-corrosion faalautele sooga mo ducts fa'amavae, fa'alava ie puipui mo ducts fa'amavae, fa'alava fa'apipi'i mo ducts fa'alava, fa'amavaega fa'alava fa'ameamea ma afifi fa'amalama eletise/vevela. FDA ma UL togi avanoa.

PTFE maualuga-vevela ie (PTFE-coated fiberglass) e ofoina atu le fa tulaga lelei autu 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), mautu dimensional (<0.5% faʻamaʻaina luga), ma non-stick elongation, ma non-stick elongation). Fa'aoga i paipa vaila'au, olo fa'asufurization, tane piki, ma mea'ai/faletalavai. FDA togi avanoa.
