Ichi chinyorwa chinovhara core performance indicators yePTFE high-temperature tepi inoshandiswa muvacuum coating, vacuum heat treatment uye nharaunda dzakafanana. Zvinodiwa zvakakosha zvinosiyana zvakanyanya nekushandiswa kwemuchadenga: kubuda kunze kunonyanya kukosha (TML≤1%, CVCM≤0.1%; aerospace / optical mamakisi anoda TML≤0.5%, CVCM≤0.01%); tembiricha kuramba kunofanira kusimbiswa kune ese ari maviri PTFE substrate (260 ° C) uye adhesive layer; yakanyatsocheneswa yakaderera-outgassing silicone PSA inodiwa kudzivirira siloxane kusvibiswa; high-temperature inobata simba inodzivirira kukambaira uye kusimudza kumucheto; utsanana hunoda kusabvisa fiber uye pasi ionic content; anti-static tepi (pamusoro resistivity 10⁶-10⁹ Ω/sq) inodzivirira ESD kukuvara; plasma kuramba kunofanirwa kuongororwa kune sputtering / PECVD maitiro; thermal shrinkage pazasi 2% inovimbisa masking chaiyo.

Ichi chinyorwa chinofananidza kamuri-tembiricha uye yakakwirira-tembiricha maturation yesilicone pressure-sensitive adhesive yePTFE tepi. High-temperature maturation (120-180 ° C) inogadzira dense crosslinked network ine simba rakasimba rakabatana, kudzivirira zvakasara zvakanamatira mushure mekusvuura. Iyo inoumba makemikari anchoring zvisungo nePTFE substrates kuburikidza ne primer co-kurapa, kubvisa delamination njodzi. High-temperature maturation inobvisawo low-molecular volatiles isati yasununguka, kudzivirira kuputika uye kusvibiswa kwesilicone mafuta panguva yekutanga kupisa.

Iri gwara rinovhara PTFE yakakwira-tembiricha tepi kusarudzwa kwejekiseni kuumba kudhonzwa uye anti-stick application. Kusarudzwa kwekushisa-based: ≤260 ° C kune mapurasitiki akawanda (standard silicone PSA tape, 0.13-0.18mm); 260-300 ° C yepamusoro-tembiricha engineering mapurasitiki sePC, PA66, POM (yakakwirira-temp silicone adhesive, 0.18-0.25mm); 300-400 ° C yePEEK, LCP, PPS pedyo nevamhanyi vanopisa (tepi yekunamatira inokundikana; shandisa jira risina pepa rePTFE kana PFA firimu). Material-based sarudzo: tacky zvinhu zvinoda yakakwirira-kuburitsa yakachena PTFE nzvimbo; girazi/mineral yakazadzwa zvinhu zvinoda inorema-basa 0.25mm+ kupfeka-resistant tepi; corrosive additives inoda makemikari anonamira uye dense substrate; static-sensitive applications inoda anti-static black PTFE tepi.

PTFE-yakavharidzirwa fiberglass jira rinoshandiswa zvakanyanya mukugadzira rabha nekuda kwekupisa kwayo, isiri-tsvimbo pfuma, uye yakaderera friction. Zvishandiso zvakakosha zvinosanganisira: kuburitsa liner dzeplate/vacuum vulcanization uye kuumba matayi; mabhandi ekutakura asina tsvimbo ezvigayo zvakavhurika, makarenda, uye mitsetse yekutonhodza; jira rinopindirana rekuchengetedza semi-yakapedza rubber; kunyanya kubata silicone uye fluororubber; uye matireyi ovheni ekuti apedze kupora. Mabhenefiti anosanganisira kubvisa mold adhesion, kudzikisa kuburitsa mumiriri kushandiswa, kudzivirira kuputira roller, uye kuve nechokwadi chekudhirowa kwakanaka.

Iyo tembiricha yegirazi yekuchinja (Tg) yesilicone yekumanikidza-inonzwa inonamira yakatenderedza -120 ° C - yakadzikira zvakanyanya kupfuura acrylic adhesives. Iyi ultra-low Tg inochengeta PTFE yakakwirira-tembiricha tepi ichichinjika uye inonamira kunyange pa -70 ° C, ichidzivirira brittle kuputika uye kugonesa kunamatira kwakavimbika mune cryogenic application.

Sarudzo yepepa rekuburitsa kana firimu substrate uye mumiriri wekuburitsa zvinokanganisa kugadzikana kwekuchengetedza uye peeling kuita kwePTFE yakakwirira-tembiricha tepi. Ichi chinyorwa chinofananidza PET vs. kraft paper substrates uye silicone vs. fluorinated release agents, inokurudzira kusanganiswa kwakakwana kwezero-residue peeling uye kuvimbika kwenguva refu.
