Ekiwandiiko kino kikwata ku nkozesa y’olugoye olwa PTFE olw’ebbugumu eringi mu bintu ebikoleddwa mu kaboni fiber flat composite. Compression molding: eteekebwa wakati w’ebibumbe ne prepregs okuziyiza epoxy resin adhesion, okusobozesa okwangu demolding; sandwiched wakati w’ebipande ebigonvu ebingi okwewala okukwatagana. Vacuum bag molding: reusable release film wakati wa prepreg ne breather cloth, okusobozesa ggaasi / resin okuyita ate nga kisobozesa okwangu okusekula oluvannyuma lw'okuwona; textured side ekyusa fine surface texture okulongoosa bonding roughness, okumalawo okusenya. Okufulumya okutambula obutasalako: emisipi egy’okutambuza egitaliiko mugongo gitwala prepregs okuyita mu bitundu ebifukirira/okunyiga; cushion layer egaba pressure kyenkanyi okukendeeza localized indentations.

Ekiwandiiko kino kyetegereza obusobozi bw’okujjanjaba ennimi z’omuliro okukyusakyusa kungulu kwa PTFE era ne kigeraageranya ebivaamu n’obujjanjabi bwa corona ne plasma. Okusobola: ennimi z’omuliro zisobola okukyusa PTFE naye nga tezitera kukozesebwa mu makolero — obulabe bw’obukuumi (PTFE evunda n’efulumya obutwa HF ne perfluoroisobutylene); omulimu gukoma (amasoboza ag’okungulu 30-35 mN/m zokka, gakola oluwuzi lw’ensalo enafu). Enkola z’okukola: ennimi z’omuliro — oxidation ey’ebbugumu eringi ey’ekiseera ekitono (>1000°C), etching entono, ebibinja bya oxygen ebitono; corona — okufuluma kwa vvulovumenti enkulu kuleeta ozone/active oxygen, oxidation etali ya maanyi, density y’amasoboza entono tesobola kumenya CF bonds; plasma — obutundutundu/obusannyalazo/free radicals ez’amasoboza amangi zikutula butereevu enkolagana za CF ne zisiba ebibinja bya polar (hydroxyl, carboxyl, amino).

Ekiwandiiko kino kigeraageranya obutuufu bw’enkola ssatu ez’okugezesa diguli y’okuwonya ku bisiiga ebikwatagana ne puleesa ya silikoni. Okuggyamu ekizimbulukusa (ebirimu ggelu) kipima ekitundu ky’omukutu ekitasaanuuka nga kiyita mu kuggyamu Soxhlet — okubalirira okusukkiridde olw’ebitundu ebizingiddwa mu mubiri ebikyamuddwa nga ebiyungo ebisalasala, obutuufu ±2-5%, obutuufu bw’eddagala obusinga wansi. DSC egera ebbugumu ly’ensengekera erisigaddewo (α=1-ΔHresidual/ΔHtotal) — eryesigika ku kukyusa okutono okudda ku kwa wakati naye esukkiridde okubalirira ku kukyusa okw’amaanyi olw’ebibinja ebisigadde ebikoma mu kusaasaana, okuddiŋŋana <±2%.

Ekiwandiiko kino kikwata ku mirimu gya PTFE mu thermal insulation cladding ku yingini za mizayiro. Enkola nnya: Endothermic decomposition — PTFE depolymerizes at ~400°C to tetrafluoroethylene (highly endothermic, ~3,000°C combustion gas exposure), okunyiga ebbugumu eddene n’okuggya amaanyi 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 bikolwa by’obusannyalazo bwa gamma-ray ku nsengekera n’eby’obugagga bya PTFE. Enkyukakyuka mu nsengekera y’eddagala: emisinde gya gamma gimenya enjegere enkulu eza CC n’enjegere z’ebbali za CF (G-value 3.0-3.5), ne kireeta okusalasala kw’enjegere okw’amaanyi n’okukendeera okw’amaanyi mu buzito bwa molekyu; mu oxygen, free radicals zikola peroxy radicals nga ziyingiza ebibinja by’enkomerero bya acyl fluoride ne carboxylic acid (okusaanuusa amazzi okutuuka ku HF). Ensengekera y’ekisengejjero ekyukakyuka: obuwundo bulinnya mu kusooka (ddoozi entono, enjegere ennyimpi ziddamu okusengeka) oluvannyuma n’egwa (ddoozi eya waggulu, obulema butaataaganya obutafaali); lamellar crystals zikutukakutuka ne zifuuka crystallites entono nga zirina ensengekera y’ewala ebula. Okwonooneka kw’eby’obugagga: okuwanvuwa ku kumenya kukendeera okuva ku 0.1 kGy mu mpewo, okufiirwa >90% ku ~1kGy — ekintu kifuuka kikaluba era kikutuka; ekifo ky’okusaanuuka kikka okuva ku 327°C okutuuka wansi wa 310°C; ebibinja by’enjuba (polar groups) bisitula katono ku dielectric constant/loss; kungulu kukyuka okuva ku njeru okudda ku nzirugavu/enzirugavu nga gloss loss.

Ekiwandiiko kino kikwata ku nkola z’okufuga obutafaali bw’okusiiga kwa PTFE ku lugoye lwa Teflon olw’ebbugumu eringi. Okulungamya omutindo gw’okunyogoza kusinga butereevu era kukola bulungi: Okunyogoza okw’amangu (okuzikiza) nga kuyita mu kateni z’empewo ennyogovu, ebizingulula ebinyogoza oba ttanka z’amazzi — enjegere za molekyu zifuuka bbugumu nga tezinnaba kuteekebwateekebwa, ne zikola obuwundo obutonotono obutatuukiridde; okusiiga kugonvu, kukaluba nga kulina omutindo ogusinga obutakwata, okukendeeza katono ku bugumu/okuziyiza okwambala. Okunyogoza mpola (annealing) nga tuyita mu kitundu ekikuuma ebbugumu ku 10-50°C/h oba okunyogoza mu kyokero — enjegere za molekyu zisengeke mu bujjuvu mu spherulites ennene ezijjuvu; okusiiga kulina obugumu obw’amaanyi, okugumira okwambala okw’enjawulo, ebipimo ebinywevu, okukendeeza ku kukyukakyuka n’okwongera okumenya.

Ekiwandiiko kino kikwata ku kusiiga olugoye lwa Teflon olw’ebbugumu eringi mu kyokero ky’okusiba empewo eyokya. Okusobola: okukozesebwa nga omutto ogutakwata ku misipi oba trays nga ebbugumu ly’ekikoomi ≤260°C (okukala mu bbugumu entono, okuggyawo binder, okuwonya slurry) — erongoosa demolding n’okulonda obulungi. Kikugirwa nnyo ku bbugumu erya wakati/wa waggulu (300-950°C) — PTFE evunda n’efulumya obutwa HF ne perfluoroisobutylene, n’evunda ebyuma era n’ereeta obutwa obutta. Omusingi gw’obukuumi: singa ebbugumu ly’ekikoomi teritegeerekeka oba nga teriyinza kukakasibwa wansi wa 260°C, tokozesa. Ebintu ebikulu: okuweereza okutambula obutasalako -70°C okutuuka ku 260°C, okw’ekiseera ekitono 300°C; obutakwata nnyo n’obutakola bulungi mu kemiko; okuziyiza amasannyalaze okulungi ennyo; okusikagana okutono (~0.04); fiberglass base egaba amaanyi ag’okusika amangi.

Ekiwandiiko kino kikwata ku sipiidi ya layini eya bulijjo ku layini y’okufulumya olugoye olw’ebbugumu eringi olwa Teflon. Sipiidi: ebintu ebigonvu ebya bulijjo (0.08-0.30mm) ku 0.5-3 m/min, stable ku 1-3 m/min; ebintu ebinene/ebifukiddwamu ebingi (≥0.4mm) ku 0.3-1 m/min; layini ezikola obulungi nga zirina oven empanvu zisobola okutuuka ku 3-6 m/min naye nga zeetaaga ebyuma. Ebiziyiza enkola: okukala n’okusiba kyetaagisa obudde bw’okubeera (PTFE yeetaaga edakiika 1-3 ku 380-400°C; obutamala kireeta okunywerera/okukutuka obubi); sipiidi esalibwawo okusinziira ku budde obutono obw’okukala/okufuumuula wansi w’obuwanvu bwa oven obutakyukakyuka. Ebiziyiza ebintu: ebisaasaana ebikalu/obuzito ebingi biyingira mpola; emifaliso eminene/eminene ginyiga amazzi ne gitambuza ebbugumu mpola; emifaliso emigazi egitera enjawulo mu langi wakati w’empenda nga kyetaagisa okukendeeza ku sipiidi. Ebikozesebwa n’omutindo okusuubulagana: oveni empanvu ezirina zooni nnyingi zisobozesa sipiidi ey’amaanyi.

Ekiwandiiko kino kikwata ku njawulo wakati wa PTFE emulsions ezikolebwa suspension polymerization vs dispersion polymerization. Okunnyonnyola: suspension polymerization tesobola kukola butereevu PTFE emulsion; emulsion ya PTFE entuufu eva mu kusaasaanya polymerization yokka. 'Suspension-method emulsion' mu butuufu ye mazzi okuyimirizaawo kwa ground suspension-polymerized resin micropowders. Dispersion polymerization (primary emulsion): obutundutundu obw’enkulungo (0.1-0.3μm, okusaasaana okufunda), obutebenkevu n’ebirungo ebikola ku ttaka ebirimu perfluorinated, obuzito bwa molekyu obw’amaanyi ennyo (>94% crystallinity), fibrillation ey’amaanyi, yeetaaga okusiba 380°C okukola firimu enkalu obutasalako.

Ekiwandiiko kino kyetegereza enkola y’ekika kya platinum catalyst n’okusengejja ku crosslinking kinetics ya addition-cure silicone rubber. Ebika by’ekirungo ekiziyiza: Ekirungo kya Speier (chloroplatinic acid, Pt4+) kyetaaga okukendeeza ku bika ebikola ebya valenti entono, nga kikola nga precatalyst; Ekirungo kya Karstedt (Pt0 nga kiriko divinyltetramethyldisiloxane) kiyingira butereevu mu nsengekera y’ekirungo ekiziyiza. Ebikolwa eby’ekika: Speier alaga ekiseera ky’okuyingiza ekimanyiddwa nga S-shaped curing curve (empola nga bukyali, eyanguwa oluvannyuma) n’amasoboza ag’okukola agalabika aga waggulu; Karstedt alaga tewali induction, high initial rate nga sharp exotherm, activation energy eya wansi.
