Ekiwandiiko kino kikwata ku byetaago by’omutindo gw’okunyogoza mu kiseera ky’okusiba olugoye olw’ebbugumu eringi mu PTFE. Oluvannyuma lw’okusiba ku 380-400°C, olugoye lulina okuyita mu bwangu mu kitundu ekiwulikika mu 310-315°C. Omuwendo gw’okunyogoza ogusemba waakiri 30-50°C/min (olugoye olugonvu lusobola okutuuka ku 100-200°C/min nga luyita mu kunyogoza kw’empewo). Okunyogoga amangu (okuzikiza) kuvaamu obutafaali obutono (45-50%), okuvaamu ebizigo ebigonvu, ebikalu nga biriko ebitundu ebiweweevu, okunywerera okw’amaanyi, okukola obulungi ennyo obutakwata, n’okuziyiza okukutuka n’okukutuka. Okunyogoga mpola (okunyogoza mu kyokero) kivaamu obutafaali bungi (60-70%), ekivaako ebizigo ebikaluba, ebimenyamenya ebitera okukendeera, okusekula n’enjatika entonotono.

Olugoye olw’ebbugumu eringi olwa PTFE olusika ennyo lukolebwa nga lusiiga PTFE ku lugoye lwa fiberglass olw’amaanyi amangi, nga luwa amaanyi g’okusika, okugumira ebbugumu, eby’obugagga ebitakwata, okuziyiza eddagala, n’okusikagana okutono. Ebikulu ebikozesebwa mulimu: okutambuza mu makolero (okupakinga ebbugumu okukendeeza, okufumba emmere, okukala engoye, okukala empapula/firimu); composite molding release olugoye ne hot press cushion liners; okuweta kateni ezikuuma n’obukooti obuziyiza ebbugumu; okuziyiza mmotoka z’amasannyalaze ne tulansifooma; okuzimba bbeeri ezisereka n’ebiwanirira payipu; okusengejja eddagala n’okusiba vvaalu mu mbeera ezivunda. Amaanyi g’okusika amangi gakakasa okuwangaala wansi w’okusika, okukutuka, okunyiga enfunda eziwera, n’okunyigirizibwa kw’ebyuma okw’ebbugumu eringi mu nkola zino ez’enjawulo ez’emirimu emizito.

Mu kiseera ky’okusiba, obutundutundu bwa PTFE ku lugoye lwa fiberglass busaanuuka waggulu wa 327°C, ne busaanyaawo lamelae ez’olujegere oluzingiddwa olw’olubereberye n’ensalosalo z’obutundutundu okukola okusaanuuka okutali kwa kifaananyi. Nga enyogoze, PTFE eddamu okufuuka ekiristaayo ne kifuuka spherulites ezikoleddwa mu lamellae ezitunudde mu radially, nga crystallinity ziri wakati wa 50–70%. Omutindo gw’okunyogoza gwe gusalawo okutuukirizibwa kwa kirisitaalo: okunyogoza mpola kuvaamu obuwundo obusingako, spherulites ennene, obukaluba obusingawo; okuzikiza amangu kiwa spherulites ennungi n’okulongoosa mu kukyukakyuka.

Ekiwandiiko kino eky’ekikugu okuva e Jiangsu Aokai kyekennenya engeri ebbugumu erisukkiridde erya wansi oba erya waggulu erya sintering gye lyonoona olugoye olwa PTFE olw’ebbugumu eringi. Okusiba okutono kuleka obutundutundu nga tebusaanuuse, ekivaako obutuli obutonotono, okukwatagana okunafu mu kusiiga-substrate, ebifo ebikalu, amaanyi g’ebyuma amabi, n’okulabika ng’amata agatali matangaavu. Okubuguma ennyo kuleeta okuvunda kw’ebbugumu lya PTFE, okuvaamu ebituli bya ppini, ebiwujjo, okumenya, okukyusa langi okuva mu kyenvu okudda ku muddugavu, n’okufulumya omukka ogw’obutwa. Ebintu byombi ebisukkiridde bisaanyawo compactness, non-stick performance, flexibility, insulation, n’okutebenkera mu dimensional.

PTFE ebbugumu eringi olugoye insulating gaskets zigatta amaanyi ga dielectric amangi (enywevu wansi w’obunnyogovu), -70 ° C okutuuka 260 ° C ebbugumu range, universal chemical resistance (okuggyako ebyuma alkali ebisaanuuse), non-stick surface (okuziyiza creepage), anti-creep (fiberglass reinforcement vs. pure PTFE), amaanyi g’okusika amangi, okusikagana okutono (μ=0.05-0.1), ne V-0 ekipimo ky’ennimi z’omuliro. Bw’ogeraageranya ne mica, kapiira, ne gaskets za PTFE ennongoofu, olugoye lwa PTFE luwa okukyukakyuka okw’ekika ekya waggulu, okulongoosebwa, n’okunyweza ebipimo okumala ebbanga eddene. Kirungi nnyo ku tulansifooma, okuziyiza mmotoka, okusiba flankisi mu kemiko, n’ebyuma bya semikondokita.

PTFE olugoye flatness nga sintering kyetaagisa precise okusika, ebbugumu, n'okufuga okuziyiza. Enkola enkulu: ekyuma kya stenter (ppini plates zikuuma obugazi, zitangira weft shrinkage), gradient temperature profile (okubuguma mpola → 380-400°C hold → slow cooling wansi wa 310°C nga tonnasumulula tension), pre-shrunk substrate (eggyawo weaving stress nga tonnazisiiga), n’obuwanvu bw’okusiiga obw’enjawulo (buziyiza differential melting). Stenter restraint erina okukuumibwa okutuusa nga enyogoga wansi w’ekifo kya PTFE crystallization point (approx. 310°C) okuziyiza warpage.

Okusiiga ekimu mu kiseera kya PTFE emulsion impregnation of fiberglass fabric ye bulamu bw’omutindo gw’ebintu. Okusiiga okutali kwa kyenkanyi kireeta: okulemererwa obutakwata (okunywerera ku bifo ebigonvu), obunafu bw’ebyuma (obungi bw’okunyigirizibwa, okukutuka), obutabeera mu ntebenkevu mu masannyalaze (voltage y’okumenya ekka okutuuka ku 1/10), okuyingira kw’eddagala (okukulukuta kw’ekinnya kya ppini), ensonga z’ebipimo (okuwuguka), n’obulema mu kukola (okutaayaaya kw’omusipi, enkyukakyuka mu buwanvu). Okusiiga okwa kimu kyetaagisa okufuga obulungi obuzito bwa emulsion, ebikalu ebirimu, okusika kw’olugoye, ebituli by’okusika, n’ebifaananyi eby’okukala/okusiba mu zoni eziwera.

PTFE olugoye olw’ebbugumu eringi luyita mu mitendera ena egy’enkyukakyuka mu nsengeka ng’ebbugumu lirinnya: wansi wa 260°C – slow micro-cracking and residual additive volatilization; ku 327°C (ekifo ky’okusaanuuka) – enkyukakyuka okuva mu kirisitaalo okudda mu ngeri etali ya kifaananyi, okusiiga kugonvuwa, kukutuka okuva mu fiberglass; 400-500°C – PTFE efulumya polimeeri (efulumya ggaasi ez’obutwa), okusiiga kubula; waggulu wa 500°C – fiberglass egonvuwa (840°C softening point) era efiirwa obulungi bw’enzimba. Sigala wansi wa 260°C obutasalako, weewale entikko za >300°C okusobola okukola obulungi.

Olugoye lwa PTFE olw’ebbugumu eringi lukolebwa nga luyita mu kufukirira omulundi gumu (okuyita okumu: okusiiga okw’amangu, okw’ebbeeyi entono, okugonvu, kungulu okukaluba nga kuliko ebituli bya ppini) oba okufukirira okunnyika emirundi mingi (okuyita 2-3+: okusiiga okuseeneekerevu, okunene, okutaliimu pinhole, PTFE content 50-70%, omulimu ogw’omutindo ogwa waggulu, ogw’omuwendo omungi). Single-dip ekwatagana ne gaasikiti ez’omutindo ogwa wansi, ebitandaalo eby’ekiseera, n’ebintu ebissa. Multi-dip yeetaagibwa ku bipande by’okufumba ebirina omutindo gw’emmere, emisipi egy’okutambuza egitakwata, ebifo ebiyitibwa circuit substrates ebya frequency enkulu, liners z’eddagala, n’obuwuka obuzimba.

PTFE ebbugumu ery’amaanyi olugoye kungulu okulongoosa kumenya eddagala inertness for bonding / printing. Enkola nnya: okuwandiika eddagala (sodium-naphthalene, amaanyi ag’okungulu 20→40-50 dyn/cm, oluwuzi oluddugavu olw’olubeerera, ensengekera ya micro-porous), okujjanjaba plasma (nano-roughening, functional group grafting, short active window), okujjanjaba corona (thin-film, okuvunda amangu, obuziba obutono), n’okulongoosa laser (precision micro-patterning, controlled carbonization). Enkola zonna zikaluba mu mubiri era mu kemiko ziyingiza ebibinja by’enjuba (C=O, -OH, -COOH) okusobozesa okukwatagana okw’okusiiga.
