Ekiwandiiko kino kyanjula enkola enkulu enzijuvu ey’okufukirira olugoye lwa fiberglass ne PTFE emulsion. Emitendera musanvu emikulu: 1 Okusooka okulongoosa (dewaxing/desizing) ku 350-400°C okuggyawo ebirungo ebipima obunene bw’engoye; 2 Emulsion formulation nga erimu ebitundu 40-55% ebikalu n’ebirungo ebikola ku ttaka okusobola okulongoosa okufukirira; 3 Okufukirira nga oyita mu nkola ya dip-squeeze oba okusiiga ekiso ky’omusawo; 4 Okukala ku 100-150°C okufuumuuka mpola amazzi n’okukola firimu ya PTFE enkalu; 5 Okusiba ku 360-390°C (okutuuka ku 400°C) okusaanuusa obutundutundu bwa PTFE mu firimu egenda mu maaso; 6 Multi-cycle impregnation-drying-sintering eddiddwamu emirundi 2-4 okutuuka ku target obuwanvu n’ebirimu resin (45-65%); 7 Oluvannyuma lw’okujjanjaba omuli okujjanjaba corona, okusala ku mbiriizi, okuzingulula n’okukebera omutindo. Ebifo ebikulu ebifuga: okuggyamu omubisi mu bujjuvu, okufukirira mu bujjuvu mu emulsion, okukala mpolampola, ebbugumu erituufu ery’okusiba, n’obungi bw’okusiiga obutakyukakyuka. Ebintu biweereza laminates ezibikkiddwa ekikomo eza frequency enkulu, conveyor belts ez’ebbugumu eringi n’ebintu ebizimba membrane.

Ekiwandiiko kino kyanjula ebizimbulukusa ebiramu olugoye lwa PTFE olw’ebbugumu eringi bye lusobola okugumira. Olugoye lwa fiberglass olusiigiddwa PTFE lulaga obutakola bwa kemiko obw’enjawulo, nga luziyiza kumpi ebizimbulukusa byonna ebya bulijjo eby’obutonde wansi w’embeera za bulijjo ez’okukola awatali kusaanuuka, kuzimba oba kukwatagana kwa kemiko. Ebika ebigumiikiriza mulimu: omwenge (methanol, ethanol, isopropanol), ketones (acetone, MEK, cyclohexanone), esters (ethyl acetate, butyl acetate), hydrocarbons (gasoline, toluene, xylene, hexane), halogenated hydrocarbons (dichloromethane, chloroform, carbon tetrachloride), ethers (diethyl ether, THF), asidi ez’obutonde (glacial acetic acid, formic acid), amines ne amides (triethylamine, DMF), phenols, n’ebirala nga carbon disulfide, pyridine, silicone oil n’amazzi ga buleeki.

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 amangu 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 empewo). Okunyogoza 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, ebikutuka ebitera okukendeera, okusekula n’okukutuka.

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, okugumira 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 ekiristaalo ne zifuuka spherulites ezikoleddwa mu lamelae 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 kyekenneenya engeri ebbugumu erisukkiridde erya wansi oba erya waggulu erya sintering gye lyonoona olugoye olw’ebbugumu eringi olwa PTFE. 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 okusukkiridde 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 dimensional.

PTFE ebbugumu eringi olugoye insulating gaskets zigatta amaanyi ga dielectric amangi (ezinywevu 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), high tensile strength, low friction (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 okusika okutuufu, 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 kwenkanankana kuleeta: 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.

Olugoye lwa PTFE 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.
