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 kyanjula ebizimbulukusa ebiramu olugoye lwa PTFE olw’ebbugumu eringi bye lusobola okugumira. Olugoye lwa fiberglass olusiigiddwa PTFE lulaga obutakola bwa kemiko obw’enjawulo, nga luziyiza kumpi ebizimbulukusa byonna ebya bulijjo eby’obutonde wansi w’embeera za bulijjo ez’okukola awatali kusaanuuka, kuzimba oba kukwatagana kwa kemiko. Ebika ebigumiikiriza mulimu: omwenge (methanol, ethanol, isopropanol), ketones (acetone, MEK, cyclohexanone), esters (ethyl acetate, butyl acetate), hydrocarbons (gasoline, toluene, xylene, hexane), halogenated hydrocarbons (dichloromethane, chloroform, carbon tetrachloride), ethers (diethyl ether, THF), asidi ez’obutonde (glacial acetic acid, formic acid), amines ne amides (triethylamine, DMF), phenols, n’ebirala nga carbon disulfide, pyridine, silicone oil n’amazzi ga buleeki.

Ekiwandiiko kino kikwata ku byetaago by’omutindo gw’okunyogoza mu kiseera ky’okusiba olugoye olw’ebbugumu eringi mu PTFE. Oluvannyuma lw’okusiba ku 380-400°C, olugoye lulina okuyita amangu mu kitundu ekiwulikika mu 310-315°C. Omuwendo gw’okunyogoza ogusemba waakiri 30-50°C/min (olugoye olugonvu lusobola okutuuka ku 100-200°C/min nga luyita mu kunyogoza empewo). Okunyogoza amangu (okuzikiza) kuvaamu obutafaali obutono (45-50%), okuvaamu ebizigo ebigonvu, ebikalu nga biriko ebitundu ebiweweevu, okunywerera okw’amaanyi, okukola obulungi ennyo obutakwata, n’okuziyiza okukutuka n’okukutuka. Okunyogoga mpola (okunyogoza mu kyokero) kivaamu obutafaali bungi (60-70%), ekivaako ebizigo ebikaluba, ebikutuka ebitera okukendeera, okusekula n’okukutuka.

Olugoye olw’ebbugumu eringi olwa PTFE olusika ennyo lukolebwa nga lusiiga PTFE ku lugoye lwa fiberglass olw’amaanyi amangi, nga luwa amaanyi g’okusika, okugumira ebbugumu, eby’obugagga ebitakwata, okugumira eddagala, n’okusikagana okutono. Ebikulu ebikozesebwa mulimu: okutambuza mu makolero (okupakinga ebbugumu okukendeeza, okufumba emmere, okukala engoye, okukala empapula/firimu); composite molding release olugoye ne hot press cushion liners; okuweta kateni ezikuuma n’obukooti obuziyiza ebbugumu; okuziyiza mmotoka z’amasannyalaze ne tulansifooma; okuzimba bbeeri ezisereka n’ebiwanirira payipu; okusengejja eddagala n’okusiba vvaalu mu mbeera ezivunda. Amaanyi g’okusika amangi gakakasa okuwangaala wansi w’okusika, okukutuka, okunyiga enfunda eziwera, n’okunyigirizibwa kw’ebyuma okw’ebbugumu eringi mu nkola zino ez’enjawulo ez’emirimu emizito.

Ekiwandiiko kino eky’ekikugu okuva e Jiangsu Aokai kyekennenya engeri ebbugumu erisukkiridde erya wansi oba erya waggulu erya sintering gye lyonoona olugoye olwa PTFE olw’ebbugumu eringi. 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 mu 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.

Enkola y’okuluka fiberglass – eya bulijjo, twill, oba satin – ekosa nnyo eby’obugagga by’olugoye olw’ebbugumu eringi mu PTFE. Satin weave ekuwa amaanyi agasinga okukutuka (2-3x plain) n’okukyukakyuka, ekirungi ennyo mu kubeebalama mu ngeri ey’amaanyi. Okuluka okwa bulijjo kuwa okunyweza okusinga obulungi mu bipimo n’okunyweza ebikuta, ebisaanira okukozesebwa mu ngeri etali ya kukyukakyuka. Twill egerageranya eby’obugagga byonna okukozesebwa abantu bonna.

Okusiiga obumu bw’olugoye olwa PTFE olw’ebbugumu eringi kisalibwawo ensonga nnya: okukola okusiiga (obunene bw’obutundutundu 0.15-0.35 μm, obuzito, ebikalu), enkola y’okusiiga & okusiiga (okusiiga ekyuma ekisinga okwettanirwa olw’obumu), omutindo gwa substrate (engeri y’okuluka, nga tebannaba kulongoosa), n’embeera y’okufulumya (20-25°C, <60% RH). Enkola ya Dip + blade combined egerageranya okuyingira n’obugonvu bw’okungulu.

Olugoye lwa PTFE olw’ebbugumu eringi luwa eddagala ery’enjawulo, ligumira asidi ez’amaanyi, alkali, ebizimbulukusa ebiramu, ne ggaasi ezivunda. Ekitundu kino kiraga ebikwata ku bintu byayo ebigumira, obuzibu (ebyuma bya alkali ebisaanuuse, ebirungo ebikola fluorinating eby’amaanyi), n’ensonga enkulu nga ebbugumu, okusengejja, n’okunyigirizibwa kw’ebyuma.

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
