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 kuyonja kusiimuula (ebyoya by’ekyuma byonoona ekifo ekitali kikwata), tereka ekifo ekigaziwa 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, weewale okusika okuyita mu bbugumu ly’enkyukakyuka ya phase, kozesa ebisika eby’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’ekyesiiga ekisaanuuka eky’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 z’okusiiga 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 obugumu 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.

Okukala ddaala ddene nnyo mu kukola emifaliso egy’ebbugumu erya waggulu erya PTFE. Ebikyamu ebitera okubaawo mulimu: okwatika (okukala amangu ennyo, okufuuka olususu ku ngulu), okusenguka kw’okusiiga (obutundutundu butambula okutuuka ku ngulu, okukwatagana okw’omunda okunafu), ebituli/ebizimba (empewo oba omukka ogusibiddwa), amabala amazungu n’okufuukuuka (okusenguka kw’ebirungo ebikola ku ttaka oba okuyungibwa okutali kujjuvu), okufuuka emmyufu/okukoola (okubuguma ennyo kw’ebirungo), okusenguka (okunyigirizibwa kw’okukendeera okusukka okunywerera), ebikuta by’emicungwa (okutereeza obubi), warpage (uneven shrinkage), kungulu kukalu naye munda mubisi (okusala olususu kutega obunnyogovu), n’empenda enzito (coffee-ring effect). Ebigonjoola bizingiramu enkola z’okukala ezifugibwa, okuyingiza empewo entuufu, n’okusooka okulongoosa substrate.

Olugoye lwa fiberglass olugaziyiziddwa (olugoye lwa wuzi olunene) lwawukana nnyo ku lugoye lwa fiberglass olwa bulijjo mu nsengeka y’obuwuzi. Okuyita mu kulongoosa empewo ya puleesa eya waggulu, obuwuzi bw’endabirwamu obutasalako bwawulwamu, ne bunywezebwa, ne bufuumuulwa ne bufuulibwa obuwuzi obunene obulinga ppamba. Kino kireeta olugoye olugonvu, olugonvu nga lulina okuziyiza ebbugumu okw’ekika ekya waggulu (layers z’empewo ezisibiddwa), okukwatagana obulungi, okukola obulungi mu kusengejja okw’amaanyi, n’okuziyiza okukutuka/okunyiga okulongooseddwa – ku muwendo gw’amaanyi g’okusika aga wansi katono. Ekozesebwa mu gaasikiti ez’ebbugumu eringi, okuzinga payipu, ensawo z’okusengejja, n’okusiba oven.
