Lapi ra mahiselo yale henhla ya PTFE ya matimba yale henhla i xivumbeko xa fiberglass ya high-tenacity na PTFE coating. Switirhisiwa swa nkoka swi katsa ku hundzisela ka ti indasitiri (ku baka swakudya, ku omisiwa ka swiambalo, ku fambisiwa ka PCB), nsirhelelo wa ku welda (swifunengeto swa heat-sealer, swisirhelelo swa spatter), demolding na ku vumba ka press yo hisa (ku vumba ka rhaba, PV lamination), ku pfaleriwa ka gezi (motor slot liners, cable wraps), ti membranes ta vumaki (mafulelo ya xitediyamu, vutomi bya malembe ya 30+), tikhemikhali ta anti-corrosion (ku andlala swihlanganisi, swifunengeto swa mathangi), swihaha-mpfhuka (swiambalo swo hisa), ni switirhisiwa swo hlawuleka (ku tsema hi laser, ku kandziyisa hi 3D).

Ku basa ka switirhisiwa swoka swinga lulamisiwanga i masungulo ya matirhelo ya lapi ra mahiselo yale henhla ya PTFE. High-purity PTFE emulsion (ku hava ti ions ta nsimbi, kungari na masalela ya low-molecular-weight) yitiyisisa ku tiya ka kuhisa (ku hava ku tshwuka kuya fika eka 260°C), non-stick leyi tiyeke, na matimba yale henhla ya dielectric. Eka fiberglass, alkali-free E-glass (Na2O <0.8%) yi hlayisa matimba xikan’we naku pfaleriwa eka mahiselo yale henhla; nghilazi ya le xikarhi/ya le henhla ya alkali yi vanga ku onhaka. Ku susiwa hiku hetiseka ka weaving sizing agents swisivela carbonization na delamination. Ku basa swi khumba hi ku kongoma vutomi bya vutirheli, ku landzelerisa ka giredi ya swakudya, na ku tshembheka ka gezi.

Vutomi bya vukorhokeri bya lapi ra mahiselo yale henhla ya PTFE byi hambana swinene kuya hi xitirhisiwa. Tikhemikhali ta anti-corrosion lining tinga tshama 3+ wa malembe (4x yo leha kutlula rhaba). Titreyi to baka swakudya ti heta tinhweti tinga onhaki ngopfu. Mabandhi yo fambisa ya tiindasitiri ya onhaka hikwalaho ka ku hlangana. PV lamination (150°C, EVA contact) yina vutomi byo ringanela. Switirhisiwa swa friction yo tika (abrasive discs) swina vutomi byo koma. Swilo swa nkoka: ku lawula mahiselo (tshama ≤260°C), papalata ku rhurhumela loku tlhavaka, ku basisiwa nkarhi na nkarhi, na ku cinciwa hi nkarhi loko ku ri na swirhumbana kumbe ku tshwuka.

Lapi ra PTFE ra mahiselo yale henhla (PTFE-coated fiberglass) ritshama nkarhi woleha swinene loko ri hlayisiwa ehansi ka 260°C, ekule na swirhendzevutani leswi karihaka, naswona ri basisiwa hi switirhisiwa swo olova. Swilo leswikulu leswi sivelaka vutomi: ku onhaka ka mahiselo ehenhla ka 260°C, ku tshoveka ka mahiselo kusuka eka ku hisa/ku kufumela hiku hatlisa, ku karhala ka michini kusuka eka ku gombonyoka naku tsana, nhlaselo wa tikhemikhali kusuka eka tinsimbi ta alkali leti n’okiweke kumbe ti oxidizers to tiya, ku onhaka kusuka eka ti scrapers ta nsimbi loko ku basisiwa, na ku hlangana na UV kuva u tirhisiwa ehandle. Khwalithi ya coating na substrate na swona swina nkoka.

PTFE high-temperature fabric (PTFE-coated fiberglass) yikahle swinene eka microwave heating hikuva yi hundzisela ti microwaves handle ko tswonga eneji, yi lwisana na 260°C, naswona yina xivumbeko lexi nga namarheliki. Switirhisiwa swikatsa ti microwave baking mats, ti industrial dryer conveyor belts, ti reactor linings ta ku gayela ti khemikhali, na ti microwave popcorn bag liners. Tigredi ta FDA leti kumekaka eka ku hlangana na swakudya.

Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) rina ku tiya ka flex lokunga kahle hikuva substrate ya fiberglass hi ntumbuluko yi brittle. Malapi yo olova (0.08mm) ya hanya eka madzana kuya eka magidi ya ku peta; ti grade to tika (>0.25mm) ti pandzeka endzhaku ka makume. Satin weave yi tlula plain weave. Eka ku gombonyoka loku yaka emahlweni ka reciprocating, languta filimi ya PTFE leyi tiyeke kumbe lapi leri sekeriweke eka aramid ematshan’wini ya sweswo.

Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) ritirhisiwa ngopfu eka ku kandziyisa swiambalo na ku daya eka mabandhi yo gandlisa yo hundzisela ku hisa (180-230°C), swifunengeto swa tafula ro gandlisa hi xikirini, mabandhi ya mesh yo omisa, mabandhi ya muchini wo fusa, na ku phutsela hi roller. Vuandlalo bya yona lebyi nga namarheli byi sivela masalela ya inki/adhesive, leswi hungutaka nkarhi wo basisa na ku antswisa khwalithi ya malapi. Mabandhi lama nga heriki lama nga riki na swirhabyani ma endla leswaku ku va ni vuhumelerisi lebyi yaka emahlweni.

PTFE lapi ra mahiselo yale henhla (PTFE-coated fiberglass) i xitirhisiwa xo sefa xa xiyimo xale henhla eka swiyimo swo tika: ku susiwa ka ntshuri wa gasi ya flue (semende, ku hisiwa ka thyaka, ti boilers ta malahla kuya fika eka 260°C), ku sefiwa ka mati lawa ya onhaka (acids, alkalis, oils), ku sefa ka swakudya/murhi leswinga sterile, na swisefo swa HEPA cleanroom. Xiphemu lexi nga namarheliki xi sivela ku caking ka ntshuri naswona swipfumelela ku basisiwa hiku olova. Ti membrane-laminated grades ti fikelela ku humesiwa ka swilo swale hansi swinene.

Lapi ra mahiselo yale henhla ra PTFE ri hlayisa ku pfaleriwa ka gezi lokunene kusuka eka -180°C kuya eka 260°C: volume resistivity >1013 Ω·cm eka 200°C, dielectric constant yitshamisekile eka 2.0-2.1. Ehenhla ka 260°C, PTFE ya olova, ya bola ehenhla ka 327°C, yi lahlekeriwa hi insulation hilaha kunga heriki. Ehansi ka 0°C, insulation ya antswisiwa kambe coating yi hundzuka brittle. Tshama endzeni ka 260°C kuva u kuma matirhelo yo tshembheka.

Lapi ra mahiselo yale henhla ya PTFE (PTFE-coated fiberglass) ri kahle swinene eka mabandhi yo fambisa swakudya hikokwalaho ka ku tiya ka rona ka 260°C eka kuhisa, -70°C ku olova ka xirhami, vuandlalo lebyi nga namarheliki, na ku landzelela FDA. Switirhisiwa swa nkoka: ti oven ta bakery (tibiscuit, xinkwa, pizza), switirhisiwa swo fambisa swakudya leswi oxiweke, tilayini to kufumeta swilondza, tithanele to titimela, swisirhelelo swo hisa, na ku phutsela hi roller. Swi hunguta ku tlanga hi nkarhi na nkarhi wo basisa.
