PTFE theipi reusability e itšetlehile ka lintlha tse 'nè: sebopeho sa sekhomaretsi (high crosslink density, low silicone migration, microphase structure for repositionable tack), substrate anchoring (surface activation + primer ho thibela phetisetso e feletseng ea sekhomaretsi), ho roala ka morao (ho lokolla lesela ho sireletsa sekhomaretsi nakong ea ho phutholoha), le ho tšoara ka nepo (sekhomaretsi se hloekileng, ho qoba sekhomaretsi se nepahetseng). Likhomaretsi tse fetotsoeng tse hlatsuoang ka metsi li ka hlaphoheloa> 90% tack kamora ho hloekisoa.

PTFE lesela la mocheso o phahameng oa mocheso oa ho baka limmete li fana ka melemo e mene ea bohlokoa: ts'ebetso e se nang thupa (ha ho na oli kapa phofo e hlokahalang, li-pastry tse bonolo li lokolloa ka mokhoa o hloekileng), mocheso o pharaletseng (-70 ° C ho ea ho 260 ° C, o bolokehile bakeng sa ontong ho ea sehatsetsing), ho sebelisoa hape (li-cycles tse likete, ho bonolo ho hloekisa), esita le conduction ea mocheso (e thibela ho chesa, ho leka-lekana ho sootho).

Lesela la mocheso o phahameng oa PTFE le bohlokoa indastering ea ho kopanya liaparo. Lisebelisoa tsa bohlokoa: mabanta a sa feleng a conveyor bakeng sa mechini e tsoelang pele e kopanyang (e thibela sekhomaretsi se chesang se qhibilihisang, se se nang wrinkles), sekoaelo se se nang thupa le lesela la ho roala likhatiso tsa mocheso o bataletseng (sireletsa lipolanete ho silafatsoa sekhomaretsi), mabanta a conveyor bakeng sa pente ea matheba / phofshoana e koaheletsoeng ka matheba. ho omisa / ho sintering), le likoahelo tsa lieta tsa tšepe bakeng sa ho hatella sampole.

Fiberglass lesela thermal shrinkage ke sesosa se ka sehloohong sa PTFE tepi dimensional ho se tsitse. Ho PTFE sintering thempereichara (360-400 ° C), masala a loha khatello ea kelello e lokolloa. Haeba e sa thibeloe, lesela lea fokotseha; haeba e thibetsoe, khatello ea kelello e patehileng e koaletsoe, e bakang ho fokotseha ha morao nakong ea ho phekola ka sekhomaretsi (150-200 ° C) le ho futhumatsa ho qetela. Tharollo: sebelisa fiberglass e behiloeng pele ho mocheso e nang le <0.5% shrinkage ho 400 ° C, ho felisa khatello ea kelello e setseng pele u roala.

Anti-static PTFE lesela le fihlellwa ka mekhoa e 'meli e meholo: ho roala doping (ho kopanya li-fillers tse tsamaisang tse kang carbon black ho emulsion ea PTFE, ho etsa marang-rang a percolation nakong ea mahloriso a bohlokoa) le substrate weaving (ho kenya likhoele tsa conductive ka har'a lesela la fiberglass). Bokaholimo ba ho hanyetsa bo laoloa ho 10⁵–10⁹ Ω. Molao-motheo: theha tsela e tsamaisang litefello tse sa fetoheng hang hang, ho thibela ho bokellana ho kotsi.

Li-thickeners tsa emulsion ea PTFE li sebetsa mesebetsi e mene ea bohlokoa: ho tsitsisa ho emisa (ho thibela ho lokisoa ha likaroloana tse teteaneng tsa PTFE), boits'oaro bo fokolang ba li-shear (viscosity e phahameng ha u phomotse, e tlaase tlas'a ho ferekanngoa bakeng sa ho roala habonolo), ho laola botebo ba ho kenella (ho laola ho kenngoa ha resin holim'a lesela la fiberglass), le ho tšoana ha filimi (e thibela ho phatloha nakong ea ho omisa). Tlhokahalo ea bohlokoa: li-thickeners li tlameha ho bola ka botlalo ho ~ 380 ° C mocheso oa sintering, li siee masala a molora ho boloka bohloeki ba ho roala le ho koala motlakase.

Lesela la PTFE le nang le mocheso o phahameng oa mocheso (PTFE-coated fiberglass) le fana ka khanyetso e ikhethang ea lik'hemik'hale, e mamellang concentrated acids (ho kenyeletsoa le aqua regia), li-alkali tse matla (mocheso oa kamore), li-solvents le li-oxidizing agents.

Lintlha tse ka sehloohong tsa moralo: primer-anchored transition layer (thibela delamination), sea-island microstructure (MQ resin Islands + polysiloxane continuous phase), gradient crosslinking (high-density inner layer for creep resistance, low-density out layer for low-temp tack), le heat-stabilized fillers (cerium resistance oxide). Phenyl-modified siloxane likarolo li hatella mocheso o tlase oa crystallization, o nolofalletsang ho fetoha ha maemo ka tlase ho -100 ° C.
