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 lizinzile ukuya kuthi ga kwi-300 ° C, kodwa emlilweni liyabola kwaye likhuphe iigesi ezinetyhefu kakhulu: i-hydrogen fluoride (HF) (i-corrosive, i-pulmonary edema) kunye ne-perfluoroisobutylene (PFIB) (ayinambala, ayinavumba, ~10x inetyhefu ngakumbi kunephosgene, i-antido). Kwakhona i-carbon monoxide, iintsalela zePFOA, kunye nokulandelela iidioxins. Iimaski zomsi eziqhelekileyo azisebenzi; sebenzisa izixhobo zokuphefumla ezizimeleyo (SCBA). Iimpawu zinokulibaziseka.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) ilungele ukufudumeza i-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 akhoyo 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. I-Satin weave igqwesa 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 olulukiweyo kunye nokudayila amabhanti oshicilelo okuhambisa ubushushu (180-230°C), amagqubu etafile eprinta isikrini, amabhanti okumisa umnatha, 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.

Ilaphu le-PTFE lobushushu obuphezulu ligcina ubushushu obugqwesileyo bobushushu ukusuka ku -180°C ukuya kuma-260°C: umthamo we-resistivity >10¹³ Ω·cm nge-200°C, i-dielectric ihlala ihleli kwi-2.0-2.1. Ngaphezulu kwe-260 ° C, i-PTFE iyathamba, ibole ngaphezu kwe-327 ° C, ilahlekelwa yi-insulation ngokusisigxina. Ngaphantsi kwe-0°C, ukugquma kuyaphucuka kodwa ukugquma kuba brittle. Hlala ngaphakathi kwe-260 ° C ukuze usebenze ngokuthembekileyo.

Ilaphu le-PTFE elinobushushu obuphezulu (i-PTFE-coated fiberglass) ilungele amabhanti okuhambisa ukutya ngenxa yokumelana nobushushu obungama-260°C, -70°C ukuguquguquka okubandayo, indawo engabambekiyo, kunye nokuthotyelwa kwe-FDA. Usetyenziso oluphambili: ii-oveni zokubhaka (iibhiskithi, isonka, ipizza), izinto zokuhambisa ukutya okuqhotsiweyo, iintambo zokupholisa iilekese, iitonela ezikhenkcezayo, izitywini zobushushu, kunye nokusonga iirola. Inciphisa inkunkuma kunye nexesha lokucoca.

Iiarhente zokugqiba umphezulu ezifakwe kwilaphu le-fiberglass phambi kokutyabeka kwe-PTFE zibalulekile kwi-PTFE yokugqibela yokusebenza kwelaphu lobushushu obuphezulu. I-Organosilane coupling agents zenza iibhulorho ze-molecular phakathi kwe-fiber yeglasi ye-inorganic kunye ne-organic PTFE, ukunyusa amandla e-peel ukusuka ku-<2 N / cm ukuya kwi-4-8+ N / cm. Unyango olufanelekileyo luphinda lukhulise ukuxhathisa ukushisa (260 ° C +), ukusebenza kwe-dielectric, kunye nokumelana neekhemikhali. Ilaphu elingaphathwanga likhokelela kwi-delamination, ukugqabhuka, kunye nobomi obufutshane benkonzo.

Ikhalenda – ukucinezela ilaphu eligqunywe nge-PTFE phakathi kweerola zesipili ezishushu kwi-360-380°C – kuguqula ngokumangalisayo ukumila komphezulu, iipropathi zokukhulula, ukungagungqi, kunye nokusebenza koomatshini. Iyanciphisa uburhabaxa ukusuka ku-Ra 0.5-1.0 μm ukuya ku-<0.05 μm, itywina i-pinholes, iphucula ukuchasana nokugqoka, kodwa iyancipha amandla okukrazula kunye nokuguquguquka. Kubalulekile ukukhulula iilitha kunye nokufakelwa kombane.
