PTFE high-temperature jira insulating gaskets inobatanidza simba guru re dielectric (yakagadzikana pasi pehunyoro), -70 ° C kusvika 260 ° C tembiricha yakasiyana, universal chemical resistance (kunze kwesimbi alkali yakanyungudutswa), kwete-stick surface (inodzivirira creepage), anti-creep (fiberglass reinforcement vs. friction μ-501), high ten μ-50. V-0 murazvo chiyero. Kuenzaniswa ne mica, rabha, uye yakachena PTFE gaskets, PTFE jira rinopa kuchinjika kwepamusoro, kurongeka, uye kwenguva yakareba dimensional kugadzikana. Yakanakira ma transformer, motor insulation, kemikari flange yekuisa chisimbiso, uye semiconductor midziyo.

PTFE high-temperature jira rinogadzirwa kuburikidza ne-single-dip impregnation (imwe pass: kukurumidza, yakaderera-mutengo, yakaonda yakapfava, yakaoma pamusoro ine pinholes) kana yakawanda-dip impregnation (2-3+ inopfuura: yakatsetseka, dense, pinhole-isina coating, PTFE content 50-70%, premium performance, yakakwirira mutengo). Single-dip inokodzera yakaderera-giredhi gaskets, mameti echinguvana, uye zvinhu zvinofema. Multi-dip inodiwa kune chikafu-giredhi yekubikira mashiti, asiri-tsvimbo conveyor mabhandi, high-frequency circuit substrates, makemikari liner, uye architectural membranes.

Raw material kuchena ndiyo hwaro hwakakosha hwePTFE yakakwirira-tembiricha machira mhando. Kusachena (zvakasara zvekutanga, ma surfactants, maion simbi, zvakasvibiswa sizing agents) zvinokonzeresa kushatisa nguva isati yakwana (mafuru, kuturuka kupfuura 260°C), nzvimbo dzisina kuenzana dzisina matanda (adhesion anchor points), kudzikiswa kwemagetsi (dielectric loss, low breakdown voltage), kuderera kwesimba remagetsi (stressing yero/stress). Yakakwirira-kuchena zviwanikwa zvinovimbisa 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.

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, zvinofumura fiberglass), hapana kuchenesa (simbi inokuvadza nzvimbo isina tsvimbo), chengetedza kupisa kwekuwedzera clearance (inodzivirira kubvaruka), uye kutsiva kana yaputika kana kupepetwa. Chitoro chakakungurutswa, kure neUV. Pfeka magirovhosi anodzivirira kupisa panguva yekubata.

High-simba PTFE high-temperature jira inoumbwa nepamusoro-tenacity fiberglass uye PTFE coating. Makiyi ekushandisa anotora maindasitiri ekutakura (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).

Kunyatsoomeswa kwejira refiberglass kwakakosha kune inotevera PTFE coating, resin impregnation, kana lamination. Mishonga mitatu mikuru: kubvisa unyoro pa 105-120 ° C (10-30 min zvichienderana nekurema), dewaxing / thermal kuchenesa pa 300-450 ° C (LOI <0.1%, kudzivisa> 500 ° C), uye preheating pa 60-100 ° C isati yaputira. Dzora tembiricha yehovhoni kufanana (±5°C), kumanikidzira kubvisa humidification, uye chengetedza machira ane silane ari pasi pe110°C. Chengetedza machira akaomeswa mumabhegi akavharwa kana makamuri akaoma (<30 ° C, <40% RH).

PTFE yakakwirira-tembiricha yejira sevhisi hupenyu hunosiyana zvakanyanya nekushandisa. Kemikari anti-corrosion lining inogona kugara makore matatu+ (4x kureba kupfuura rabha). Chikafu chekubika matireyi mwedzi yapfuura nekuderera kudiki. Industrial conveyor mabhandi anopfeka kubva mukukweshana. PV lamination (150°C, EVA kuonana) ine upenyu huri pakati nepakati. Heavy friction applications (abrasive discs) ine hupenyu hupfupi. Zvinhu zvakakosha: kudzora tembiricha (gara ≤260 ° C), dzivirira kutsemuka kwakapinza, kuchenesa nguva dzose, uye kutsiva panguva yakakodzera kana blistered kana yero.

PTFE high-temperature fabric (PTFE-coated fiberglass) inogara kwenguva refu kana ichichengetwa pasi pe260°C, kure nezvinopinza, uye kucheneswa nemidziyo yakapfava. Zvinhu zvikuru zvinomisa upenyu: kuderera kwekushisa kwepamusoro pe260 ° C, kuvhunduka kwekushisa kubva kukurumidza kupisa / kutonhora, kuneta kwemagetsi kubva pakukotama uye kukakavara, kurwisa kwemakemikari kubva kusimbi yakanyungudutswa yealkali kana maoxidizer akasimba, kukuvadzwa kubva kusimbi scrapers panguva yekuchenesa, uye UV kuratidzwa kwekushandisa kunze. Hunhu hwekuputira uye substrate zvakare hune basa.

PTFE high-temperature fabric (PTFE-coated fiberglass) yakanakira microwave kudziyisa nekuti inoendesa microwaves isingatore simba, inopikisa 260°C, uye ine nzvimbo isina tsvimbo. Zvishandiso zvinosanganisira ma microwave ekubikira, mabhandi ekuomesera emuindasitiri, mareactor linings ekugayiwa kwemakemikari, uye microwave popcorn bag liner. FDA mamakisi anowanikwa kune chikafu chekubata.
