Ilaphu le-PTFE elinobushushu obuphezulu liveliswa nge-single-dip impregnation (ipasi enye: ngokukhawuleza, ngexabiso eliphantsi, isambatho esibhityileyo, indawo erhabaxa enemibhobho) okanye i-multi-dip impregnation (i-2-3+ idlula: i-coating egudileyo, eshinyeneyo, i-pinhole-free, umxholo we-PTFE 50-70%, ukusebenza kwe-premium, ixabiso eliphezulu). Idiphu enye ifanela iigaskets zomgangatho ophantsi, iimethi zexeshana, kunye nezinto eziphefumlayo. I-Multi-dip iyafuneka kumaphepha okubhaka ebakala lokutya, amabhanti okuhambisa angenamisitho, i-high-frequency circuit substrates, ii-chemical liners, kunye ne-architectural membranes.

I-PTFE-coated fiberglass sintering yelaphu ifuna ixesha elichanekileyo lokubamba kwi-370-400 °C. Iifurnas eziqhubekayo: 30-90s (encinci) ukuya kwi-3-5 + min (ebanzi). Izithando zeBatch: 5-15 min. I-under-sintering ibangela i-opaque, iingubo ezinqabileyo eziqhekezayo; i-sintering kakhulu ibangela ukuba tyheli, ukubhitya, kunye nokukhutshwa kwerhasi eyityhefu yefluoride. Ukulungiswa kwenkqubo: sebenzisa i-trackers zeqondo lokushisa, yenza uhlolo olubonakalayo (i-semi-transparent, flexible), kwaye wenze iimvavanyo zokutsala iteyiphu. Ngalo lonke ixesha qinisekisa ukutyeba okupheleleyo kobushushu obufanayo.

Ilaphu le-PTFE lobushushu obuphezulu lifuna ukuphathwa ngononophelo ukuqinisekisa ukhuseleko kunye nobomi obude. Amanyathelo okhuseleko angundoqo: ungaze udlule kwi-260 ° C (ngaphezulu kwe-320 ° C ikhupha umsi oyityhefu), thintela ukukrazuka okubukhali (iintanda zokugquma, ukuveza i-fiberglass), akukho ukucocwa kwe-abrasive (uboya bentsimbi yonakalisa umphezulu ongekho intonga), gcina i-thermal clearance clearance (ithintela ukukrazuka), kwaye endaweni yayo xa idutyulwe okanye ixotyulwe. Ivenkile iqengqiwe, kude neUV. Nxiba iiglavu ezikhusela ukushisa ngexesha lokuphatha.

Ilaphu elinobushushu obuphezulu be-PTFE liyi-high-tenacity fiberglass kunye ne-PTFE coating. Izicelo eziphambili zokuhambisa ushishino (ukubhaka ukutya, ukomiswa kwelaphu, ukuthuthwa kwePCB), ukukhuselwa kwewelding (izigqubuthelo zobushushu-sealer, amakhaka okutshiza), ukubunjwa kunye nokwenza ucinezelo olushushu (irabha yokubumba, i-PV lamination), ukugqunyelelwa kombane (i-motor slot liners, ukusonga kwentambo), iinwebu zokwakha (uphahla lwesitediyamu, ulwandiso lwemichiza ye-anti-corrosion, iminyaka engama-30+), i-aerospace (iingubo ze-thermal), kunye nezicelo ezikhethekileyo (ukusika i-laser, ukuprintwa kwe-3D).

Ubomi benkonzo yelaphu lobushushu obuphezulu be-PTFE buyahluka kakhulu ngokwesicelo. I-Chemical anti-corrosion lining ingahlala iminyaka eyi-3+ (i-4x ubude kunerabha). Iitreyi zokubhaka ukutya kwiinyanga ezidlulileyo kunye nokuthotywa okuncinci. Iibhanti zokuthutha zemizi-mveliso zinxiba ukusuka kwingxabano. I-PV lamination (150 ° C, EVA contact) inobomi obuphakathi. Ukusetyenziswa kwe-friction enzima (i-abrasive discs) inobomi obufutshane. Izinto eziphambili: ukulawulwa kweqondo lokushisa (ukuhlala ≤260 ° C), ugweme ukukrazula okubukhali, ukucocwa rhoqo, kunye nokutshintshwa ngexesha elifanelekileyo xa i-blistered okanye iphuzi.

Ilaphu le-PTFE elinobushushu obuphezulu (PTFE-coated fiberglass) lihlala ixesha elide xa ligcinwe ngaphantsi kwe-260 ° C, kude neendawo ezibukhali, kwaye zicocwe ngezixhobo ezithambileyo. Izinto eziphambili ezithintela ubomi: ukuthotywa kwe-thermal ngaphezulu kwe-260 ° C, ukothuka kwe-thermal ukusuka kubushushu obukhawulezayo / ukupholisa, ukudinwa komatshini ngenxa yokugoba kunye noxinzelelo, uhlaselo lweekhemikhali ezivela kwisinyithi esinyibilikisiweyo sealkali okanye i-oxidizers eyomeleleyo, ukonakaliswa kwi-scrapers yesinyithi ngexesha lokucoca, kunye nokuvezwa kwe-UV kusetyenziso lwangaphandle. Umgangatho wokugquma kunye ne-substrate nayo ibalulekile.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) ilungele ukufudumeza kwi-microwave kuba ihambisa ii-microwaves ngaphandle kokufunxa amandla, imelana ne-260°C, kwaye inomphezulu ongabambekiyo. Usetyenziso lubandakanya iimethi zokubhaka ze-microwave, amabhanti okuhambisa esomisi mveliso, iilena zereactor zokwetyisa imichiza, kunye ne-microwave popcorn bag liners. Amanqaku e-FDA afumanekayo kuqhagamshelwano lokutya.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) inoxhathiso olulambathayo ngenxa yokuba i-fiberglass substrate i-brittle ngokwendalo. Amalaphu abhityileyo (0.08mm) ahlala kumakhulu ukuya kumawaka emigobe; amabakala anzima (>0.25mm) aqhekeke emva kwamashumi. Ukuluka kweSatin kugqwesa ukuluka okucacileyo. Ukugoba okuqhubekayo, cinga ifilimu ye-PTFE eqinileyo okanye ilaphu elisekelwe kwi-aramid endaweni yoko.

Ilaphu le-PTFE elinobushushu obuphezulu (PTFE-coated fiberglass) lisetyenziswa kakhulu kushicilelo lwelaphu kunye nokudayila amabhanti oshicilelo okuhambisa ubushushu (180-230°C), izigqubuthelo zetafile yoshicilelo lwesikrini, amabhanti emesh owomileyo, amabhanti omatshini wokufunxa, kunye nokusonga ngerola. Umphezulu wayo ongeyena intonga ukhusela i-inki / i-adhesive residu, ukunciphisa ixesha lokucoca kunye nokuphucula umgangatho welaphu. Amabhanti angenasiphelo angenasiphelo enza imveliso eqhubekayo.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) yi-premium media filter kwiimeko ezigqithisileyo: ukususwa kwerhasi ye-flue (isamente, ukutshisa inkunkuma, iibhoyila zamalahle ukuya kwi-260 ° C), ukuhluzwa kolwelo oludlekayo (i-acids, i-alkalis, i-oyile), ukutya / ukuhluzwa kwe-pharmacy oyinyumba, kunye nezihluzo ze-HEPA. Umphezulu ongagxiliyo uthintela ukugquma uthuli kwaye uvumela ukucoca lula. Amanqaku e-Membrane-laminated afumana ukukhutshwa kwe-ultra-low.
