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.

Raw material kuchena ndiyo hwaro hwakakosha hwePTFE yakakwirira-tembiricha machira mhando. Kusachena (zvakasara zvekutanga, ma surfactants, maion simbi, macontainated sizeng agents) anokonzera kushatisa nguva isati yakwana (mafuru, kuturuka kupfuura 260°C), kusaenzana kusiri kwetsvimbo (adhesion anchor points), kuderedzwa kwemagetsi ekuisa (dielectric loss, low breakdown voltage), kuderera kwesimba remagetsi (stressing yero/stress). Yakakwirira-kuchena mbishi zvinhu inovimbisa FDA-inoenderana, hupenyu hurefu, yakakwirira-inoshanda PTFE jira.

PTFE-yakavharwa nefiberglass jira sintering inoda chaiyo kubata nguva pa370-400°C. Mavhiri anoenderera mberi: 30-90s (yakaonda) kusvika 3-5+ min (yakakora). Batch furnaces: 5-15 min. Under-sintering inokonzera opaque, rough coatings kuti peel; kunyanya-sintering kunokonzera kutsvuka, brittleness, uye muchetura fluoride gasi kusunungurwa. Maitiro ekugonesa: shandisa tembiricha yekutevera tembiricha, ita yekutarisa yekuona (semi-pachena, inochinjika), uye ita tepi kudhonza bvunzo. Nguva dzose iva nechokwadi chekuzara-kuzara kwekushisa kufanana.

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 high-temperature jira inoda kungwarira kubata kuti ive nechokwadi chekuchengetedza uye hupenyu hurefu. Chengetedzo yakakosha: usambopfuura 260°C (pamusoro pe320°C inoburitsa utsi hune muchetura), dzivirira kutsemuka (pakatsemuka kuvharwa, kufumura fiberglass), hapana kuchenesa (simbi inokuvadza nzvimbo isina tsvimbo), chengetedza kupisa kwekuwedzera clearance (inodzivirira kubvaruka), uye kutsiva kana yaputika kana kusvunurwa. Chitoro chakakungurutswa, kure neUV. Pfeka magirovhosi anodzivirira kupisa panguva yekubata.

PTFE high-temperature jira ine coefficient of thermal expansion (CTE) ye 30-60 ppm/°C (warp/weft) - yakakwirira kudarika fiberglass chete asi yakaderera zvikuru pane yakachena PTFE (100-200 ppm/°C). PTFE inongoerekana yachinja vhoriyamu (1-2%) pa19°C uye 30°C shanduko yechikamu. Kuti udzivise kuputika, kubvarura, uye delamination: dhizaini yedhizaini yekuwedzera mahara, dzivirira kushushikana kuburikidza nechikamu chekuchinja tembiricha, shandisa otomatiki tensioner pamabhandi ekutakura, uye shandisa anti-buckling overlap dhizaini. Kugara uchiongorora kutonhora kuyerera kwakakosha.

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.

PTFE high-temperature machira ekubikisa mabheti anopa mana akakosha mabhenefiti: kusashanda kwetsvimbo (hapana mafuta kana hupfu hunodiwa, mabheki akapfava anoburitswa zvakachena), tembiricha yakakura (-70 ° C kusvika 260 ° C, yakachengeteka muhovhoni kusvika mufiriji), kushandiswazve (zviuru zvemajini, zviri nyore kuchenesa), uye kunyange kupisa conduction (kunodzivirira kupisa, kudzikamisa brown). Chikafu-giredhi FDA inoenderana, ivo vanobuda kunze bepa rematehwe uye kupfuura e-silicone mats ane zvirinani kutamisa kupisa uye kunaka kwepamusoro magadzirirwo.

PTFE high-temperature jira yakakosha muindasitiri yenguo interlining. Zvishandiso zvakakosha: mabhandi asingagumi ekutakura mabhandi ekuenderera mberi kusanganisa michina (inodzivirira inopisa inonyunguduka inonamatira, isina kuunyana kutakura), isina-tsvimbo yekuvharira uye jira repadhi remashina ekupisa (anodzivirira maplatens kubva pakusvibiswa kweanonamatira), mabhandi ekutakura e dot paste/powder coating inlines kuomesa/kunyungudutsa), uye mavhavha eshangu dzesimbi yekutsikirira muenzaniso. Hukobvu hunotangira pa 0.13mm (light padding) kusvika 0.55mm (heavy-duty conveyor belts).

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.
