Olugoye lwa PTFE olw’ebbugumu eringi lukolebwa nga luyita mu kufukirira omulundi gumu (okuyita okumu: okusiiga okw’amangu, okw’ebbeeyi entono, okugonvu, kungulu okukalu 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 eby’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.

Obulongoofu bw’ebintu ebisookerwako gwe musingi omukulu ogw’omutindo gw’olugoye olwa PTFE olw’ebbugumu eringi. Obucaafu (ebitandisi ebisigadde, ebikola ku ttaka, ayoni z’ebyuma, ebipima obucaafu) bireeta okuvunda kw’ebbugumu nga tekunnabaawo (ebiwujjo, ebizimba waggulu wa 260°C), ebifo ebitali bikwatagana (ebifo ebinyweza ennanga), okukendeeza ku kuziyiza amasannyalaze (okufiirwa kw’amasannyalaze, vvulovumenti y’okumenya wansi), amaanyi g’ebyuma okunafuwa (okunyigirizibwa, okukutuka), n’ okufuuka ekya kyenvu/okukyuka langi. Ebintu ebisookerwako ebirongoofu ennyo bikakasa nti olugoye lwa PTFE olutuukana n’amateeka ga FDA, luwangaala nnyo, nga lukola bulungi.

Okusiba olugoye lwa fiberglass olusiigiddwa PTFE kyetaagisa obudde obutuufu obw’okukwata ku 370-400°C. Ebikoomi ebitasalako: 30-90s (ebigonvu) okutuuka ku ddakiika 3-5+ (ebinene). Ebikoomi by’ekibinja: eddakiika 5-15. Okusiba wansi kireeta ebizigo ebitali bitangaavu, ebikalu ebisekula; okusiba ennyo kireeta okufuuka okwa kyenvu, okumenyaamenya, n’okufulumya omukka gwa fluoride ogw’obutwa. Okulongoosa enkola: kozesa ebilondoola ebbugumu ly’ekikoomi, kola okwekenneenya okulabika (semi-transparent, flexible), n’okukola okugezesa okusika tape. Bulijjo kakasa nti ebbugumu ly’obuwanvu obujjuvu likwatagana.

Olugoye lwa PTFE olw’ebbugumu eringi lwetaaga okukwata n’obwegendereza okukakasa obukuumi n’okuwangaala. Ebikulu eby’okwegendereza: tosukka 260°C (waggulu wa 320°C efulumya omukka ogw’obutwa), weewale ebiwujjo ebisongovu (eyatika okusiiga, eraga fiberglass), tewali kwoza kusiimuula (ebyoya by’ekyuma byonoona ekifo ekitali kikwata), tereka ekifo eky’okugaziwa ebbugumu (kiziyiza okukutuka), era zzaawo ng’ofunye ebizimba oba ebisekuddwa. Store rolled, okuva ku UV. Yambala ggalavu eziziyiza ebbugumu ng’ozikwata.

Olugoye lwa PTFE olw’ebbugumu eringi lulina omugerageranyo gw’okugaziwa kw’ebbugumu (CTE) ogwa 30-60 ppm/°C (warp/weft) – waggulu okusinga fiberglass yokka naye nga wansi nnyo okusinga PTFE ennongoofu (100-200 ppm/°C). PTFE efuna enkyukakyuka ez’amangu mu bunene (1-2%) ku nkyukakyuka za phase eza 19°C ne 30°C. Okwewala okusiba, okukutuka, n’okukutuka: dizayini y’ebifo ebiwanvu okusobola okugaziwa okw’eddembe, okwewala okusika okuyita mu bbugumu ly’enkyukakyuka ya phase, kozesa okusika okw’otoma ku misipi egy’okutambuza, era ssaako dizayini y’okukwatagana okuziyiza okubumbulukuka. Okukebera buli kiseera okulaba oba waliwo amazzi agakulukuta mu nnyonta kyetaagisa.

PTFE high-temperature fabric baking mats ziwa ebirungi bina ebikulu: okukola obulungi obutakwata (tekyetaagisa mafuta oba buwunga, pastries enzirugavu zifuluma bulungi), ebbugumu erigazi (-70°C okutuuka ku 260°C, tezirina bulabe eri oven okutuuka mu freezer), okuddamu okukozesebwa (enkumi n’enkumi z’enzirukanya, nnyangu okuyonja), n’okutuuka n’okutambuza ebbugumu (eziyiza okwokya, balanced browning). Etuukana n’omutindo gw’emmere eya FDA, ziwangaala okusinga empapula z’amaliba era zisinga obutebe bwa silikoni nga zitambuza ebbugumu obulungi n’obutonde obulungi ku ngulu.

Olugoye olwa PTFE olw’ebbugumu eringi kyetaagisa nnyo mu mulimu gw’okusiba engoye wakati. Ebikulu ebikozesebwa: emisipi egy’okutambuza egitalina nkomerero egy’ebyuma ebifuyira obutasalako (eziyiza okunywerera kw’ekisiiga eky’okusaanuuka okw’ebbugumu, okutambuza okutaliimu nviiri), ekibikka ekitali kikwata n’olugoye olusiba olw’ebyuma ebinyiga ebbugumu ebipapajjo (ekuuma platens okuva ku bucaafu bw’okusiiga), emisipi egy’okutambuza layini za dot paste/powder coating (ekuuma ennyiriri ezisiiga ezitaliiko kamogo mu kiseera ky’okukala/okuyingirira), ne ebibikka engatto eby’ekyuma okusobola okunyiga sampuli. Obugumu buva ku mm 0.13 (light padding) okutuuka ku mm 0.55 (heavy-duty conveyor belts).

Olugoye lwa PTFE oluziyiza okutambula (anti-static PTFE fabric) lutuukibwako nga tuyita mu nkola bbiri enkulu: okusiiga doping (okutabula conductive fillers nga carbon black mu PTFE emulsion, okukola percolation network ku critical concentration) ne substrate weaving (okuteeka conductive fibers mu fiberglass cloth). Obuziyiza obw’okungulu bufugibwa ku 105–109 Ω. Omusingi: tonda ekkubo eritambuza amazzi erifulumya emisanvu egy’obutakyukakyuka mu bwangu, ne liziyiza okukuŋŋaanyizibwa okw’obulabe. Grounding kikakatako okusobola okukola obulungi.

Olugoye lwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) luwa obuziyiza obw’enjawulo obw’eddagala, okugumira asidi omungi (nga mw’otwalidde ne aqua regia), alkali ez’amaanyi (ku bbugumu erya bulijjo), ebizimbulukusa ebiramu, n’ebirungo ebifuula omukka. Okujjako: ebyuma bya alkali ebisaanuuse n’ebirungo bya halogen eby’ebbugumu eringi bilumba PTFE. Okwonooneka kw’okusiiga kulaga fiberglass asidi wa hydrofluoric ne alkali ezirimu amazzi agookya. Ebbugumu erisukka 260°C likendeeza ku buziyiza. Ku mbeera z’eddagala ezisinga obungi, olugoye lwa PTFE lusigala nga lunywevu nnyo era nga lwesigika.
