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 amazzi gakulukuta 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).

Okukendeera kw’ebbugumu mu lugoye lwa fiberglass kye kisinga okuvaako obutabeera mu ntebenkevu mu bipimo bya PTFE tape. Ku bbugumu ly’okusiba erya PTFE (360-400°C), okunyigirizibwa kw’okuluka okusigaddewo kufulumizibwa. Singa taziyizibwa, olugoye lukendeera; singa kiziyizibwa, okunyigirizibwa okukwese kusibirwa mu, ekivaako okukendeera oluvannyuma mu kiseera ky’okuwonya okw’okusiiga (150-200°C) n’okufumbisa ku nkomerero y’okukozesa. Ekigonjoola: kozesa fiberglass eyateekebwawo nga tennabuguma nga <0.5% ekendedde ku 400°C, okumalawo okunyigirizibwa okusigaddewo nga tonnasiiga.

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.

PTFE emulsion impregnation of fiberglass fabric yeetaaga abayambi ab’enjawulo okutuuka ku uniform coating, okunywerera okw’amaanyi, n’ebifo ebitaliiko bulema. Ebikulu ebigattibwamu mulimu: ebirungo ebifukirira (okukendeeza ku kunyigirizibwa kungulu, okulongoosa okuyingira), ebigonza (okufuga obuzito n’obuzito bw’okusiiga), ebitereeza pH (okutebenkeza emulsion ku pH 9-10), ebirungo ebiyunga silane (okutumbula okunywerera ku ndabirwamu), ebiyamba okukola firimu (PFA/FEP for sintering), ebijjuza ebikola (okuziyiza okwambala, okutambuza), ebifulumya effumba (okuziyiza pinholes), n’ebifuuwa amazzi (okukala mpola). Okulonda kisinziira ku substrate n’ebyetaago by’omulimu.

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.

Olugoye olwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) kumpi terukola kemiko, naye ebintu ebimu bireeta okukulukuta mu mbeera ezenjawulo. Obulumbaganyi bwa PTFE obutereevu bubaawo n’ebyuma bya alkali ebisaanuuse (sodium, potassium), ebirungo eby’amaanyi ebifuuwa fluorinating (F2, ClF3) ku bbugumu erya waggulu, ne alkali ez’amaanyi ezisaanuuse waggulu wa 300°C. Okukulukuta okutali kwa butereevu kubaawo nga asidi wa hydrofluoric (HF), alkalis ayokya, oba asidi wa phosphoric ayokya biyingidde mu bulema bw’okusiiga ne bilumba ekifo ekirimu fiberglass. Ku mpeereza y’eddagala erisukkiridde, kozesa firimu ya PTFE ennongoofu nga temuli fiberglass.

Olugoye lwa PTFE olw’ebbugumu eringi (PTFE-coated fiberglass) lulina okugumira ebbugumu okulungi ennyo mu bbanga lyalwo erya bulijjo ery’okukola okuva ku -70°C okutuuka ku 260°C. Kisobola okugumira enzirukanya y’ebbugumu ey’amangu, okugeza, okuva mu firiiza ya -50°C okudda ku press eyokya eya 260°C. Ebika bya premium bituuka n’okuwona okunyogoga okw’amangu okuva ku 260°C okudda mu mazzi aga 10°C. Naye okukankanya ekintu okuva ku bbugumu erisukka 300°C (okumpi n’ekifo kya PTFE eky’okusaanuuka ekya 327°C) kijja kuleeta enjatika n’okukutuka amangu. Ekintu ekiyitibwa fiberglass substrate kiwa obutebenkevu mu bipimo; ekizigo kya PTFE kye kikoma.

PTFE olugoye olw’ebbugumu eringi lukozesebwa nnyo mu makolero g’eddagala olw’emirimu emikulu musanvu: flange gaskets ne pipe linings (guziyiza acids/alkali ez’amaanyi), reactor ne tank linings (guziyiza ebyuma okukulukuta, okwangu okuyonja), ensawo z’okusengejja omukka ogukulukuta (okutuuka ku 260°C), anti-corrosion expansion joints for ducts, anti-adhesion welding pads, olugoye olufulumya okubumba composite, n’okuzinga amasannyalaze/ebbugumu. Ebigezo bya FDA ne UL biriwo.
