Ekiwandiiko kino kikwata ku mirimu gya PTFE mu thermal insulation cladding ku yingini za mizayiro. Enkola nnya: Endothermic decomposition — PTFE depolymerizes ku ~400°C okutuuka ku tetrafluoroethylene (highly endothermic, ~3,000°C combustion gas exposure), okunyiga ebbugumu eddene n’okuggya amasoboza ag’ebbugumu okuva ku bbugwe kungulu. Okunyogoza okufuumuuka n’okuziyiza firimu ya ggaasi — ggaasi ezivunda (tetrafluoroethylene) ziyita ebweru nga ziyita mu micro-pores, ne ziggyawo ebbugumu ery’okungulu; firimu ya ggaasi ekulukuta eyawula ggaasi ey’okwokya ey’ebbugumu eringi okuva ku bbugwe, n’ekendeeza ku kutambula kw’ebbugumu okumpi n’ekisenge >50%; firimu ya ggaasi ekyusa sipiidi/ebbugumu ly’oluwuzi lw’ensalo, okukendeeza ku kukulugguka kw’obutundutundu.

Ekiwandiiko kino kikwata ku kukozesa olugoye lwa Teflon olw’ebbugumu eringi (PTFE-coated fiberglass fabric) mu kisaawe ky’omu bwengula. Ebitundu ebikulu eby’okukozesa: Okukola ebintu ebikozesebwa — okufulumya olugoye/firimu mu autoclave molding, layers ez’okwawula, emisipi egy’ebbugumu eringi okusobola okufulumya prepreg; Yingini n’okukuuma ebbugumu ery’amaanyi — emifaliso egiziyiza ebbugumu, ebibikka ku bbugwe w’omuliro, ebiyungo ebikyukakyuka eby’ebbugumu eringi; Okuziyiza amasannyalaze n’okukuuma waya — okuzinga waya mu bisenge bya yingini n’ebifo ebiteekebwamu ggiya; Munda mu nnyonyi n’okukuuma omuliro — kateni z’omuliro/ebiziyiza omukka ebituukana n’omutindo gwa FST, okubikka bulangiti eziziyiza ebbugumu/amaloboozi; Okukozesa mu bwengula n’omu bwengula — enkuŋŋaana z’okuziyiza ebbugumu (MLI), ebyuma ebisiiga ebiziyiza ennyogovu (anti-cold-weld lubrication liners) ku nkola z’okuteeka ebyuma by’enjuba n’ennyiriri za antenna, olugoye olufuga ebbugumu.

Ekiwandiiko kino kyekenneenya engeri okulongoosa omusenyu oba okumaliriza matt gye kukosaamu ensengekera y’okungulu y’olugoye olwa PTFE olw’ebbugumu eringi. Enkyukakyuka zibaawo mu bitundu bisatu: Enkula ya microscopic ekyuka okuva ku smooth mirror-like okudda ku rough gully texture nga eyongedde nnyo ku miwendo gya Ra/Rz, okukola 3D mechanical anchoring structures for subsequence bonding. Obugumu bw’okusiiga bwolekedde akabi: okugonza layeri ya PTFE, okuyinza okubikkulwa kwa fiberglass substrate (ekivaako okufiirwa eby’obugagga ebitali bya kukwata, okuyingira kw’obunnyogovu, n’okukendeeza ku maanyi g’ebyuma), n’okwongerako microcracks n’okutondebwa kw’ebisasiro.

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 ebizimba membrane.

Ekiwandiiko kino eky’ekikugu okuva e Jiangsu Aokai kyekenneenya engeri ebbugumu erisukkiridde erya wansi oba erya waggulu erya sintering gye lyonoona olugoye olw’ebbugumu eringi olwa PTFE. Okusiba okutono kuleka obutundutundu nga tebusaanuuse, ekivaako obutuli obutonotono, okukwatagana okunafu mu kusiiga-substrate, ebifo ebikalu, amaanyi g’ebyuma amabi, n’okulabika ng’amata agatali matangaavu. Okubuguma okusukkiridde kuleeta okuvunda kw’ebbugumu lya PTFE, okuvaamu ebituli bya ppini, ebiwujjo, okumenya, okukyusa langi okuva mu kyenvu okudda ku muddugavu, n’okufulumya omukka ogw’obutwa. Ebintu byombi ebisukkiridde bisaanyawo compactness, non-stick performance, flexibility, insulation, n’okutebenkera dimensional.

Okukola kalenda – okunyiga olugoye olusiigiddwa PTFE wakati w’ebiwujjo by’endabirwamu ebibuguma ku 360-380°C – kikyusa nnyo enkula y’okungulu, eby’obugagga by’okufulumya, obutayita mu mazzi, n’enkola y’ebyuma. Kikendeeza ku bukaluba okuva ku Ra 0.5-1.0 μm okutuuka ku <0.05 μm, kisiba ebituli bya ppini, kitereeza okuziyiza okwambala, naye kikendeeza ku maanyi g’okukutuka n’okukyukakyuka. Kyetaagisa nnyo ku layers ezifulumya n’okuziyiza amasannyalaze.

Nga omukugu mu kukola emifaliso egya PTFE egy’ebbugumu eringi, Jiangsu Aokai New Materials ekuwa amagezi ag’ekikugu. Ekigendererwa ekikulu eky’okulongoosa kungulu kwa fiberglass kwe kuzimba omutala gwa molekyu wakati wa fiberglass etali ya kiramu ne PTFE ey’obutonde, okusobola okugonjoola mu musingi inc yaabwe ey’obuzaale
