Anti-static PTFE jira rinowanikwa nenzira mbiri huru: kupfekedza doping (kusanganisa conductive mafirita senge kabhoni dema muPTFE emulsion, kugadzira percolation network panguva yakaoma concentration) uye substrate weaving (kupinza conductive fibers mu fiberglass jira). Surface resistivity inodzorwa pa10⁵–10⁹ Ω. Iyo musimboti: gadzira iyo conductive nzira inodonhedza static charges ipapo, kudzivirira kuunganidzwa kune njodzi. Grounding inosungirwa kuti ishande inoshanda.

Thickeners muPTFE emulsion inoshanda mabasa mana akakosha: kumisa kudzikamisa (kunodzivirira kugadzika kwe dense PTFE particles), shear-kuonda maitiro (yakakwirira viscosity pakuzorora, yakaderera pasi pekushungurudzika kwekuvhara nyore), kupinza kudzika kwekudzora (inodzora resin kurodha pamucheka wefiberglass), uye kufanana kwefirimu (inodzivirira kuputika panguva yekuomesa). Chinodiwa chakakosha: makobvu anofanira kuora zvachose pa ~ 380 ° C sintering tembiricha, achisiya zero madota asara kuti achengetedze kuchena kwekupfeka uye kuvharwa kwemagetsi.

PTFE high-temperature fabric (PTFE-coated fiberglass) inopa yakasarudzika makemikari kuramba, withstanding concentrated acids (kusanganisira aqua regia), alkali yakasimba (pakamuri tembiricha), organic zvinonyungudutsa, uye oxidizing agents. Kunze kwe: simbi yakanyungudutswa yealkali uye yakakwirira-tembiricha halogen makomisheni anorwisa PTFE. Kukuvadzwa kwekuputira kunofumura fiberglass kune hydrofluoric acid uye inopisa yakadzika alkalis. Tembiricha iri pamusoro pe260°C inoderedza kuramba. Kune akawanda emakemikari nharaunda, PTFE jira rinoramba rakagadzikana uye rakavimbika.

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.

High-simba PTFE high-temperature jira inoumbwa nepamusoro-tenacity fiberglass uye PTFE coating. Makiyi ekushandisa anotora maindasitiri ekufambisa (kubika chikafu, kuomesa machira, kutakura PCB), kuchengetedzwa kwechivharo (kupisa-sealer mavhavha, spatter nhovo), dhizaini uye inopisa kuumba (rabha kuumba, PV lamination), magetsi ekuisa (motor slot liners, tambo wraps), architectural membranes (stadium matenga, 30 + kugadzirwa kwemakemikari makore), aerospace (magumbeze anopisa), uye akakosha maapplication (laser kucheka, 3D kudhinda).

Kuomesa inhanho yakakosha muPTFE yakakwirira-tembiricha yekugadzira machira. Zvikanganiso zvakajairika zvinosanganisira: kutsemuka (kunyanya kuomesa, kuomeswa kwepamusoro), kubhururuka kutama (zvimedu zvinofamba kumusoro, hukama hwemukati husina simba), pinholes / blisters (mhepo yakavharirwa kana mhepo), mavara machena uye chalking (kusimuka kwesurfactant kana kusakwana kusanganiswa), kutsvuka / kubikira (kupisa kwezvinowedzera), delamination (kudonha kana kunyungudika kweorenji) shrinkage), pasi pakaoma asi mukati memvura (kusvuura mateya unyoro), uye mipendero yakakora (kofi-ring effect). Mhinduro dzinosanganisira kudzora kuomesa profiles, kufefetedza kwakaringana, uye substrate pretreatment.

Iyo yakachekwa yekupedzisira kumeso chimiro chePTFE yakakwira-tembiricha tepi inokanganisa zvakananga kunama kuyerera uye kusimudza kumucheto panguva yekushandisa. Kutsemura kusina kunaka (mablades akagomara, kona isina kufanira) kunogadzira glue filaments, kutetepa kumucheto kwenamira layer, uye kunofumura mabhura efiberglass - zvichitungamira mukuyerera, kusimba kusungirirana, uye kusimudza mukupisa kana kunetsana. Zviso zvisina kujairika zviso (wavy, protruding) zvinokonzeresa kusaenzana kwekudzvanywa, kutyaira kunamira kunokwira panguva yekuchengetedza. Iyo yakanakira magumo chiso yakatsetseka, inotsvedza, uye isina kukuvara - ichiita sechisimbiso chinokiya chinonamira uye chinova nechokwadi chese kumucheto kusungirirwa.

PTFE emulsion impregnation yemucheka wefiberglass inoda vabatsiri vakasiyana-siyana kuti vakwanise kupfekedza yunifomu, kunamatira kwakasimba, uye nzvimbo dzisina kukanganisa. Zvinowedzera zvekuwedzera zvinosanganisira: wetting agents (kuderedza kushushikana kwepasi, kunatsiridza kupinda), thickeners (control viscosity uye coating uremu), pH regulators (stabilize emulsion papH 9-10), silane coupling agents (kunamatirisa kune girazi), firimu-forming aids (PFA/FEP ye sintering), inoshanda mafirita (kupfeka mapikisi, maconductors ekudzivirira) (slow drying). Kusarudzwa kunoenderana ne substrate uye kuita zvinodiwa.

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).
