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 kunama peeling), adhesive 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), nzira dzekurongedza (waya bonding fixation, soldering mask yePCBs), uye kugadzirisa midziyo (anti-static roller kuputira, kucherekedza mukamuri yekumaka). Ultra-yakachena zvinodiwa: yakaderera halogens (inodzivirira bond pad corrosion), yakaderera siloxanes (<500 ppm, inodzivirira insulating particle formation), low metal ions (<1 ppm imwe neimwe), ISO Class 4 cleanroom slitting/packaging, 10⁶-10⁹ Ω pasi pepamusoro peOC 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 ekutevedza 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 (pamusoro activation + primer kudzivirira yakazara adhesive kutamiswa), kuseri kwekuvhara (kuburitsa layer kuchengetedza adhesive panguva yekusunungura), uye kubata kwakaringana (yakachena-inonamatira tekinoroji, kudzivirira kwakachena nzira yekunamira). Mvura-inogezwa yakagadziridzwa inonamira inogona kupora> 90% tack mushure mekuchenesa.

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 nhanho), gradient crosslinking (yakakwirira-density yemukati layer yezvinokambaira, yakaderera-density yekunze layer kune yakaderera-temp tack), uye kupisa-yakagadzikana mafiritsi (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 ePTFE, 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.

Munguva yePTFE tepi yekuputira, iyo inonyungudutsa volatilization mwero wesilicone pressure-sensitive adhesive ndiyo yakakosha process parameter. Kunyanya kukurumidza → kukwenya pamusoro, kusadzikama zvakanaka, mapini (akavharirwa solvent), uye craters (condensation kana tsvina-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).

PTFE high-temperature tepi inorasikirwa nekunamatira mushure mekushandisa kakawanda nekuda kwekusvibiswa kwepamusoro (guruva, silicone mafuta), kusungirirwa kwakabatana kukundikana (kusara), kana kusimba kwe substrate bonding. Mhinduro: high-crosslink silicone PSA (yakaderera kutama, kuenzanisa tack / kubata simba), primer treatment paPTFE substrate, dense fiberglass backing, uye kubata kwakakodzera (nzvimbo dzakachena, ganda rinotonhorera, 180 ° angle). Quantitative test inosimbisa kuvandudzwa.

PTFE high-temperature tepi yakachengetwa pasi pemamiriro akatarwa (10-25 ° C, 40-70% RH, kure neUV / heavy pressure) ine mararamiro esherufu emwedzi 3-6 (makirasi ekutanga kusvika kumwedzi gumi nemiviri). Key degradation zvikumbaridzo: simba repeel harifanire kudonha pasi pe70% yekutanga kukosha; hapana masara ekunamatira mushure mekubviswa kwekushisa kwepamusoro; hapana carbonization kana kutsemuka pane yakatarwa tembiricha. Macheki anokurumidza: manyore kusunungura kunzwa, 260 ° C yasara bvunzo, uye lamination shrinkage bvunzo.
