PTFE olugoye olw’ebbugumu eringi (PTFE-coated fiberglass) lye ssengejjero ery’omutindo ogwa waggulu eri embeera ezisukkiridde: okuggya enfuufu ya ggaasi w’omukka (seminti, okwokya kasasiro, bboyiyira z’amanda okutuuka ku 260°C), okusengejja amazzi agakulukuta (asidi, alkali, amafuta), okusengejja emmere/eddagala eritaliimu buwuka, n’okusengejja ebisenge ebiyonjo ebya HEPA. Ekitundu ekitali kikwata kiziyiza enfuufu okucake era kisobozesa okwanguyirwa okuyonja. Grades ezikoleddwa mu membrane-laminated zituuka ku bucaafu obutono ennyo.

PTFE olugoye olw’ebbugumu eringi lukuuma okuziyiza amasannyalaze okulungi ennyo okuva ku -180°C okutuuka ku 260°C: obuziyiza obunene >1013 Ω·cm ku 200°C, dielectric constant stable ku 2.0-2.1. Waggulu wa 260°C, PTFE egonvuwa, evunda waggulu wa 327°C, n’efiirwa insulation enkalakkalira. Wansi wa 0°C, insulation etereera naye okusiiga kufuuka brittle. Sigala mu 260°C okusobola okukola obulungi.

Olugoye lwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) lulungi nnyo ku misipi egy’okutambuza emmere olw’okugumira ebbugumu lya 260°C, -70°C okukyukakyuka mu nnyonta, kungulu okutakwata, n’okugoberera FDA. Ebikulu ebikozesebwa: oveni z’okufumba emigaati (bisikiiti, omugaati, pizza), ebyuma ebitambuza emmere esiike, layini ezinyogoza ssweeta, emikutu egy’okufumbisa, ebisiba ebbugumu, n’okuzinga roller. Kikendeeza ku kasasiro n’obudde bw’okuyonja.

Ebirungo ebimaliriza kungulu ebisiigibwa ku lugoye lwa fiberglass nga tebannaba kusiiga PTFE bikulu nnyo mu kukola olugoye olw’ebbugumu eringi olwa PTFE olusembayo. Ebirungo ebiyunga organosilane bikola ebibanda bya molekyu wakati wa fiber y’endabirwamu etali ya kiramu ne PTFE ey’obutonde, ne bitumbula amaanyi g’ebikuta okuva ku <2 N/cm okutuuka ku 4-8+ N/cm. Okujjanjaba obulungi era kwongera ku bugumu (260°C+), okukola kwa dielectric, n’okuziyiza eddagala. Olugoye olutali lulongooseddwa luvaako okukutuka, okubumbulukuka, n’okuwangaala okumpi.

Warp ne weft density y’olugoye lwa fiberglass esalawo PTFE omulimu gw’olugoye olw’ebbugumu eringi. Densite eya waggulu eyongera ku maanyi g’okusika n’obugonvu bw’okungulu naye ekendeeza ku maanyi g’okukutuka (inverted U-curve), okukyukakyuka, n’okuyingira kw’ekizigo. Densite ennungi egerageranya okuyingira, okuziyiza okukutuka, okukyukakyuka, n’okumaliriza kungulu. Densite entono ekwatagana n’okubeebalama okw’amaanyi; density enkulu ku non-stick ne insulation.

Okukola kalenda – okunyiga olugoye olusiigiddwa PTFE wakati w’ebiwujjo by’endabirwamu ebibuguma ku 360-380°C – kikyusa nnyo enkula y’okungulu, eby’obugagga by’okufulumya, obutayita mu mazzi, n’enkola y’ebyuma. Kikendeeza ku bukaluba okuva ku Ra 0.5-1.0 μm okutuuka ku <0.05 μm, kisiba ebituli bya ppini, kitereeza okuziyiza okwambala, naye kikendeeza ku maanyi g’okukutuka n’okukyukakyuka. Kyetaagisa nnyo ku layers ezifulumya n’okuziyiza amasannyalaze.

Omusono gw’okuluka fiberglass – ogwa bulijjo, twill, oba satin – gukosa nnyo eby’obugagga by’olugoye olw’ebbugumu eringi mu PTFE. Satin weave ekuwa amaanyi agasinga okukutuka (2-3x plain) n’okukyukakyuka, ekirungi ennyo mu kubeebalama mu ngeri ey’amaanyi. Okuluka okwa bulijjo kuwa okunyweza okusinga obulungi mu bipimo n’okunyweza ebikuta, ebisaanira okukozesebwa mu ngeri etali ya kukyukakyuka. Twill egerageranya eby’obugagga byonna okukozesebwa abantu bonna.

Okusiiga ekimu ku lugoye lwa PTFE olw’ebbugumu eringi kisalibwawo ensonga nnya: okukola okusiiga (obunene bw’obutundutundu 0.15-0.35 μm, obuzito, ebikalu), enkola y’okusiiga & okusiiga (okusiiga ekyuma ekisinga okwettanirwa olw’obumu), omutindo gwa substrate (enkola y’okuluka, nga tebannaba kulongoosa), n’embeera y’okufulumya (20-25°C, <60% RH). Enkola ya Dip + blade combined egerageranya okuyingira n’obugonvu bw’okungulu.

Okwoza n’okuddaabiriza obulungi kwongera ku bulamu bw’olugoye lwa PTFE olw’ebbugumu eringi. Okwoza ng’omaze okukozesa n’oluvannyuma lw’okunyogoza. Kozesa bbulawuzi ennyogovu, eby’okunaaba ebitaliimu oba omwenge ku mabala. Tokozesangako asidi/alkali ez’amaanyi, bleach, oba ebyuma ebisenya. Okusiiga amafuta ga silikoni buli kiseera kikendeeza ku kwambala. Goberera ebiragiro bino okutangira ebizigo okwonooneka.

Olugoye lwa PTFE olw’ebbugumu eringi n’olugoye lwa silicone byombi bikozesa olugoye lwa fiberglass nga base naye nga byawukana mu bintu ebisiiga (PTFE resin vs silicone rubber). PTFE esinga mu butakwata, okugumira okwambala, n’okugumira eddagala okutuuka ku 260°C. Olugoye lwa silicone luwa okukyukakyuka okw’ekika ekya waggulu, okuziyiza amasannyalaze, n’okuziyiza omuliro (okutuuka ku 230°C). Londa okusinziira ku ky’olina okukulembeza.
