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 ebikozesebwa mu kuzimba.

Ekiwandiiko kino kikwata ku bipimo ebikulu ebiraga omulimu gwa PTFE high-temperature tape ekozesebwa mu vacuum coating, vacuum heat treatment n’embeera ezifaananako bwe zityo. Ebyetaago ebikulu byawukana nnyo ku nkozesa y’empewo: okufulumya omukka kisinga kukulu (TML≤1%, CVCM≤0.1%; ebigezo by’omu bwengula/eby’amaaso byetaaga TML≤0.5%, CVCM≤0.01%); okuziyiza ebbugumu kulina okukakasibwa ku byombi PTFE substrate (260°C) ne adhesive layer; silikoni PSA erongooseddwa mu ngeri ey’enjawulo efulumya omukka omutono yeetaagibwa okuziyiza obucaafu bwa siloxane; amaanyi agakwata ku bbugumu erya waggulu gaziyiza okusitula n’okusitula ku mabbali; obuyonjo bwetaaga obutayiwa fiber ate nga n’obungi bwa ionic butono; anti-static tape (okuziyiza kungulu 106-109 Ω/sq) kuziyiza ESD okwonooneka; okuziyiza kwa pulasima kulina okwekenneenyezebwa ku nkola z’okufuuwa/PECVD; okukendeera kw’ebbugumu wansi wa 2% kukakasa nti masking precision.

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 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. Okunyogoza mpola (okunyogoza mu kyokero) kivaamu obutafaali bungi (60-70%), ekivaako ebizigo ebikaluba, ebikutuka ebitera okukendeera, okusekula n’okukutuka.

Ekiwandiiko kino kigeraageranya okukula kw’ebbugumu ly’ekisenge n’ebbugumu eringi ery’ekyesiiga ekikwata ku puleesa ya silikoni ku ttaapu ya PTFE. Okukula mu bbugumu eringi (120-180°C) kuleeta emikutu eminene egy’omusalaba nga girina amaanyi ag’amaanyi ag’okukwatagana, okuziyiza ebisigadde eby’okusiiga oluvannyuma lw’okusekula. Ekola enkolagana ezisiba eddagala (chemical anchoring bonds) ne PTFE substrates nga ziyita mu primer co-curing, okumalawo obulabe bw’okukutuka. Okukula mu bbugumu eringi nakyo kiggyawo ebiwunya ebirina molekyu entono nga tonnazaala, ne kiziyiza okubumbulukuka n’obucaafu bwa woyiro wa silikoni mu kiseera ky’okusooka okubugumya.

Ekitabo kino kikwata ku PTFE high-temperature tape okulonda for injection molding demolding n'okukozesa anti-stick. Okulonda okusinziira ku bbugumu: ≤260°C ku buveera obw’awamu (standard silicone PSA tape, 0.13-0.18mm); 260-300°C ku buveera bwa yinginiya obw’ebbugumu eringi nga PC, PA66, POM (ekisiiga kya silikoni eky’ebbugumu erya waggulu, 0.18-0.25mm); 300-400°C ku PEEK, LCP, PPS okumpi n’abaddusi ababuguma (tepi eyesiiga eremererwa; kozesa olugoye lwa PTFE olutaliimu kwesiiga oba firimu ya PFA). Okulonda okwesigamiziddwa ku bintu: ebintu ebikwatagana (tacky materials) byetaaga high-release pure PTFE surfaces; ebintu ebijjudde endabirwamu/eby’obuggagga bw’omu ttaka byetaaga obutambi obuzitowa obwa mm 0.25+ obugumira okwambala; ebirungo ebikulukuta byetaaga ebizigo ebigumira eddagala n’ebintu ebinene; enkola ezikwata ku static zeetaaga anti-static black PTFE tape.

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.

Olugoye lwa fiberglass olusiigiddwa PTFE lukozesebwa nnyo mu kukola emipiira olw’okugumira ebbugumu, obutakwata, n’okusikagana okutono. Ebikulu ebikozesebwa mulimu: okufulumya liners okukola plate/vacuum vulcanization n’okubumba emipiira; emisipi egitambuza ebintu egitakwata ku byuma ebiggule, kalenda, ne layini ezinyogoza; olugoye lw’okuyunga (interleave cloth) okutereka emipiira egya semifinished; okukwata mu ngeri ey’enjawulo ku silikoni ne fluoroubber; ne oven trays okusobola okuziwonya oluvannyuma. Emigaso mulimu okumalawo okunywerera kw’ekikuta, okukendeeza ku nkozesa y’ekirungo ekifulumya, okuziyiza okuzinga ebiwujjo, n’okulaba ng’okuggya ekikuta mu ngeri ennungi.

Okusiba okutono kuleka PTFE nga tesaanuuse, ekivaako micro-pores, okunywerera obubi, ebifo ebikalu, amaanyi g’ebyuma amatono, n’okulabika ng’amata. Okubuguma ennyo kwonoona PTFE, ne kivaamu ebituli bya ppini, ebiwujjo, okumenya, langi ya kyenvu okutuuka ku ddugavu, n’omukka ogw’obutwa. Zombi zoonoona compactness, non-stick performance, flexibility, insulation, n’okutebenkera mu bipimo. Ekifo ekisinga obulungi 370–400°C kivaamu okusiiga okutali kwa bulambulukufu, okuseeneekerevu, okwa langi ya tan. Okukebera okulaba: matte white = under-sintered; kyenvu/brittle = okusensera ennyo.
