Okusiiga ekimu mu kiseera kya PTFE emulsion impregnation of fiberglass fabric ye bulamu bw’omutindo gw’ebintu. Okusiiga okutali kwenkanankana kuleeta: okulemererwa obutakwata (okunywerera ku bifo ebigonvu), obunafu bw’ebyuma (obungi bw’okunyigirizibwa, okukutuka), obutabeera mu ntebenkevu mu masannyalaze (voltage y’okumenya ekka okutuuka ku 1/10), okuyingira kw’eddagala (okukulukuta kw’ekinnya kya ppini), ensonga z’ebipimo (okuwuguka), n’obulema mu kukola (okutaayaaya kw’omusipi, enkyukakyuka mu buwanvu). Okusiiga okwa kimu kyetaagisa okufuga obulungi obuzito bwa emulsion, ebikalu ebirimu, okusika kw’olugoye, ebituli by’okusika, n’ebifaananyi eby’okukala/okusiba mu zoni eziwera.

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, okwewala okusika okuyita mu bbugumu ly’enkyukakyuka ya phase, kozesa okusika okw’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’ekisiiga eky’okusaanuuka okw’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 za 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 obuziyiza 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.

Aokai PTFE yasoose kulaga ebintu byayo byonna mu mpaka za APFE Shanghai 2026 (Booth 6T602, Hall 6). Ebintu ebiragiddwa mulimu obutambi bwa PTFE obunywezeddwa fiberglass, firimu za PTFE ennongoofu, ebigero ebiziyiza okutambula, n’emisipi egy’ebbugumu eringi – nga gibikka ku kulongoosa emmere, PV lamination, bbaatule za lithium, ebyuma, n’okupakinga. Omwoleso guno gugenda mu maaso okutuuka nga June 26. Ebintu byonna biwagira custom specifications.

Olugoye olw’amaanyi amangi olwa PTFE olw’ebbugumu eringi lukoleddwa mu fiberglass ezinywevu ennyo n’okusiiga kwa PTFE. Ebikulu ebikozesebwa bikwata ku kutambuza mu makolero (okufumba emmere, okukala engoye, entambula ya PCB), okukuuma okuweta (ebibikka ku bbugumu-sealer, engabo ezifuuwa), demolding n’okukola ekyuma ekikuba ebyuma ebibuguma (okubumba emipiira, PV lamination), okuziyiza amasannyalaze (motor slot liners, cable wraps), okuzimba membranes (obusolya bw’ekisaawe, obulamu bw’emyaka 30+), eddagala eriziyiza okukulukuta (okugaziya ebiyungo, ebisenge bya ttanka), eby’omu bbanga (emifaliso egy’ebbugumu), n’okukozesebwa okw’enjawulo (okusala layisi, okukuba ebitabo mu ngeri ya 3D).

Okukala ddaala ddene nnyo mu kukola emifaliso egy’ebbugumu erya waggulu erya PTFE. Ebikyamu ebitera okubaawo mulimu: okwatika (okukala amangu ennyo, okufuuka olususu ku ngulu), okusenguka kw’okusiiga (obutundutundu butambula okutuuka ku ngulu, okukwatagana okw’omunda okunafu), ebituli/ebizimba (empewo oba omukka ogusibiddwa), amabala amazungu n’okufuukuuka (okusenguka kw’ekirungo ekikola ku ttaka oba okuyungibwa okutali kujjuvu), okufuuka emmyufu/okukoola (okubuguma ennyo kw’ebirungo ebigattibwako), okusenguka (okunyigirizibwa kw’okukendeera okusukka okunywerera), ebikuta by’emicungwa (okutega obubi), warpage (uneven shrinkage), kungulu kukalu naye munda mubisi (okusala olususu kutega obunnyogovu), n’empenda enzito (coffee-ring effect). Ebigonjoola bizingiramu enkola z’okukala ezifugibwa, okuyingiza empewo entuufu, n’okusooka okulongoosa substrate.

PTFE emulsion impregnation of fiberglass fabric yeetaaga abayambi ab’enjawulo okutuuka ku uniform coating, okunywerera okunywevu, n’okubeera n’obulema. Ebikulu ebigattibwako 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), okuggya effumba (okuziyiza pinholes), n’ebifuuwa amazzi (okukala mpola). Okulonda kisinziira ku substrate n’ebyetaago by’omulimu.
