PTFE tepi yekemikari pombi/mudziyo anti-corrosion, isiri-tsvimbo, uye chisimbiso kudzivirira kunoda kuenzanisa substrate, adhesive system, uye makemikari media. Silicone PSA inokurudzirwa 200-260 ° C ine acids / alkalis; acrylic PSA inopikisa organic solvents asi inomisa tembiricha kusvika ≤150°C. PaHF, kufashaira >80% alkali, kana chlorine trifluoride, shandisa PTFE-chete lining (hapana organic adhesive). Yakakosha: kunamatira ndiyo isina kusimba chinongedzo, kwete iyo PTFE pachayo.

PTFE tepi inobata simba inovandudzwa kuburikidza nekuvhara uye kurapa maitiro ekugadzirisa. Coating: primer layer (0.5-2μm silane primer inodzivirira kunamira kusvuura), kunamira ukobvu 30-60μm (yakanyanya kubata simba), vacuum defoaming, uye 5-10μm kusefa. Kurapa: kudziyisa kwakadzika nhanho (80-100°C kubviswa kwe solvent → 120-140°C kuumba → 150-220°C deep crosslinking), post-curing (40-60°C for 24-48h to relax stress), uye low-tension conveyance kudzivirira kushushikana kwemukati kubva substrate shrinkage. Iyo yekutanga yakakosha kune PTFE yakaderera pamusoro pesimba.

PTFE high-temperature tepi inoshanda sechinhu chakakosha mukugadzira semiconductor, kwete general-purpose consumable. Zvishandiso zvakakosha: wafer-level dziviriro (plasma etching masking, CMP backside protection, CVD/PVD masking), kurongedza maitiro (waya bonding fixation, soldering mask yePCBs), uye kugadzirisa midziyo (anti-static roller kuputira, kucherekedza mukamuri yekumaka). Ultra-yakachena zvinodiwa: low halogens (inodzivirira bond pad corrosion), yakaderera siloxanes (<500 ppm, inodzivirira insulating particle formation), yakaderera simbi ions (<1 ppm imwe neimwe), ISO Class 4 cleanroom slitting/packaging, 10⁶-10⁹ Ω TV surface resistivity, uye low TV surface resistivity.

Medical-giredhi PTFE yakakwirira-tembiricha tepi inosanganisa biocompatible PTFE substrate ine platinamu-yakapora silicone adhesive. Zvinhu zvakakosha: ISO 10993 inoenderana (hapana cytotoxicity, sensitization, kana kushatirwa), inoshingirira kudzokororwa sterilization (steam/EO/gamma), 260°C kupisa kuramba. Chengetedzo dzakakosha: usapfuure 260°C (hutsi hunokachidza huri pamusoro pe300°C), gamma irradiation inogona kukonzera kubvongodzwa, kusimbisa nzira dzesterilization, uye kukumbira magwaro ekutevedzera akazara (ISO 10993 mishumo, MSDS, data yekuchembera). Kwete yeropa rakananga kana kushandiswa kwekuisirwa kunze kwekunge kwakanyatso kusimbiswa.

PTFE tepi reusability inoenderana nezvinhu zvina: adhesive formulation (yakakwira crosslink density, yakaderera silicone migration, microphase chimiro che repositionable tack), substrate anchoring (surface activation + primer kudzivirira yakazara inonamira kutamiswa), kuseri kwebhandi (kuburitsa layer kuchengetedza adhesive panguva yekusunungura), uye kubata kwakakodzera (yakachena-inonamira nzira, kudzivirira kwakachena-anonamira pamusoro. Mvura-inogezwa yakagadziridzwa inonamira inogona kupora> 90% tack mushure mekuchenesa.

Fiberglass fabric thermal shrinkage ndiyo inonyanya kukonzera PTFE tepi dimensional kusagadzikana. Pa PTFE sintering tembiricha (360-400 ° C), zvakasara zvekuruka kushushikana kunoburitswa. Kana isingadzoreki, jira rinopera; kana ikadziviswa, kushushikana kwakadzikama kunovharirwa mukati, zvichiita kuti gare gare kupera panguva yekunamatira kurapa (150-200 ° C) uye kupera-kushandiswa kupisa. Mhinduro: shandisa pre-heat-set fiberglass ne <0.5% shrinkage pa 400 ° C, kubvisa kushushikana kwakasara kusati kwavhara.

Yakakura-tembiricha-yakasiyana-siyana PTFE tepi inoda silicone PSA inochengetedza kunamatira kubva -70°C kusvika 260°C. Makiyi ekugadzira zvinhu: primer-anchored transition layer (inodzivirira delamination), sea-island microstructure (MQ resin zvitsuwa + polysiloxane inoenderera chikamu), gradient crosslinking (yakakwirira-density yemukati layer yezvinokambaira, yakaderera-density yekunze layer kune yakaderera-temp tack), uye kupisa-yakagadzika mafirita (cerium oxide). Phenyl-modified siloxane segments inodzvinyirira yakaderera-tembiricha crystallization, ichigonesa kuchinjika pazasi -100°C.

Aokai PTFE yakatanga mutsara wayo uzere wechigadzirwa paAPFE Shanghai 2026 (Booth 6T602, Hall 6). Zvigadzirwa zvinoratidzwa zvinosanganisira matepi efiberglass-akasimbiswa PTFE, mafirimu ePTFE akachena, anti-static mamakisi, uye mabhandi ekutakurisa-anovhara chikafu, PV lamination, lithium mabhatiri, zvemagetsi, uye kurongedza. Chiratidziro chinoenderera kusvika munaJune 26. Zvigadzirwa zvose zvinotsigira zvakatemwa zvetsika.

Iyo yakachekwa yekupedzisira kumeso chimiro chePTFE yakakwira-tembiricha tepi inokanganisa zvakananga kunamira kuyerera uye kusimudza kumucheto panguva yekushandisa. Kutsemura kusina kunaka (mablades akagomara, kona isina kufanira) kunogadzira glue filaments, kutetepa kumucheto kwekunamira, uye kunoburitsa fiberglass burrs - zvichitungamira mukuyerera, kusimba kubatanidza, uye kusimudza mukupisa kana kunetsana. Zviso zvisina kujairika zviso (wavy, protruding) zvinokonzeresa kusaenzana kwekudzvanywa, kutyaira kunamira kunokwira panguva yekuchengetedza. Iyo yakanakira magumo kumeso yakatsetseka, inotsvedza, uye isina kukuvara - ichiita sechisimbiso chinokiya chinonamira uye chinova nechokwadi chakazara kumucheto chisungo.

Munguva yePTFE tepi yekuputira, iyo inonyungudutsa volatilization mwero wesilicone pressure-sensitive adhesive ndiyo yakakosha process parameter. Kunyanya kukurumidza → kukwenya pamusoro, kusaenzana zvakanaka, mapini (akavharirwa solvent), uye craters (condensation kana contaminant-induced). Kunyanya kunonoka → kuderera, makobvu macheto, uye kunyorova pane yakaderera-pamusoro-simba PTFE. Iro zano rakakodzera: kunonoka kwekutanga kuvhuvhuta kwekuenzanisa uye kupukunyuka kwebubble, wobva wawedzera kuomesa kuumbwa. Shandisa zvinonyungudutsa zvakasanganiswa (toluene/xylene + kukurumidza kuomesa) uye tembiricha yehovhoni yegradient (yakaderera → yepakati → yakakwirira).
