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’okulongoosa okuziyiza okukutuka/okunyiga – ku muwendo gw’amaanyi g’okusika amatono. Ekozesebwa mu gaasikiti ez’ebbugumu eringi, okuzinga payipu, ensawo z’okusengejja, n’okusiba oven.

Obulongoofu bw’ebintu ebisookerwako gwe musingi gw’omutindo gw’olugoye olwa PTFE olw’ebbugumu eringi. Emulsion ya PTFE ey’obulongoofu obw’amaanyi (tewali ion za kyuma, tewali bisigalira bya molekyu bitono) ekakasa okuziyiza ebbugumu (tewali kufuuka kwa kyenvu okutuuka ku 260°C), okunywevu obutakwata, n’amaanyi ga dielectric amangi. Ku fiberglass, E-glass etaliimu alkali (Na2O <0.8%) ekuuma amaanyi n’okuziyiza ku bbugumu erya waggulu; endabirwamu eya medium/high-alkali ereeta okuvunda. Okuggyawo ddala ebirungo ebizimba obunene mu kuluka kiziyiza carbonization ne delamination. Obulongoofu bukosa butereevu obulamu bw’obuweereza, okugoberera omutindo gw’emmere, n’okwesigamizibwa kw’amasannyalaze.

Okukaza obulungi olugoye lwa fiberglass nga tekunnabaawo kikulu nnyo mu kusiiga kwa PTFE okuddirira, okufukirira resin, oba okusiba. Enkola ssatu enkulu: okuggya obunnyogovu ku 105-120°C (eddakiika 10-30 okusinziira ku buzito), okuggyamu omubisi/okuyonja mu bbugumu ku 300-450°C (LOI <0.1%, okwewala>500°C), n’okusooka okubugumya ku 60-100°C nga tonnasiiga. Fuga obutafaanagana bwa bbugumu lya oven (±5°C), okukaka okuggya obunnyogovu, era okukuuma emifaliso egyalongooseddwa silane wansi wa 110°C. Teeka olugoye olukalu mu nsawo ezisibiddwa oba ebisenge ebikalu (<30°C, <40% RH).

PTFE high-temperature tape erina okuziyiza okufuuyira omunnyo okulungi ennyo, naye ebinafu ye adhesive layer ne fiberglass substrate edges. Enkola z’okwekenneenya: okugezesa 1000h neutral salt spray (NSS), okupima okusigala kw’amaanyi g’ebikuta (≥80% kyetaagisa), obulema mu kulaba (okusitula, okuzimba ebizimba), n’okukulukuta kw’ekyuma wansi. Ku mbeera z’ennyanja n’ez’omunnyo omungi: kozesa silicone PSA (si acrylic), PTFE substrate efumbiddwa mu bujjuvu, ssinga ku mbiriizi n’ekiziyiza embeera y’obudde, era osiige primer ku byuma.

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.

PTFE tape ya bbugumu eringi efiirwa okunywerera oluvannyuma lw’okugikozesa enfunda eziwera olw’obucaafu obw’okungulu (enfuufu, amafuta ga silikoni), okulemererwa kw’okukwatagana kw’okusiiga (ebisigadde), oba okusiba kwa substrate okunafu. Ebigonjoolwa: high-crosslink silicone PSA (okusenguka okutono, balanced tack/holding power), okujjanjaba primer ku PTFE substrate, dense fiberglass backing, n’okukwata obulungi (okuyonja kungulu, cool peel, 180° angle). Okukebera mu bungi kukakasa okulongoosa.

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 ekyuma 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.

Teepu ya PTFE ey’ebbugumu eringi eterekeddwa mu mbeera eziragiddwa (10-25°C, 40-70% RH, ewala okuva ku UV/puleesa enzito) erina obulamu obw’omutindo obw’okutereka emyezi 3-6 (ebigezo ebya waggulu okutuuka ku myezi 12). Ebikulu ebipima okuvunda: amaanyi g’okusekula tegalina kukka wansi wa 70% ku muwendo ogwasooka; tewali bisigalira bya kwesiiga oluvannyuma lw’okuggyawo ku bbugumu eringi; tewali kaboni oba enjatika ku bbugumu erigereddwa. Okukebera amangu: okuwulira okusumulula mu ngalo, okugezesa ebisigadde ku 260°C, n’okugezesa okukendeera kwa lamination.

PTFE olugoye olw’ebbugumu eringi (PTFE-coated fiberglass) luwa ebirungi bina ebikulu nga anti-corrosion lining: eddagala obutakola (guziyiza aqua regia, alkalis ez’amaanyi, solvents), ebbugumu erigazi (-70°C okutuuka ku 260°C continuous, 350°C peak), dimensional stability (<0.5% elongation), n’obutakwata kungulu (easy okuyonja, kiziyiza okuzimba). Ekozesebwa mu payipu z’eddagala, eminaala egy’okuggyamu ekibiriiti, ttanka z’okusiika, n’ebyuma ebikozesebwa mu mmere/eddagala. Ebigezo bya FDA biriwo.
