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 ti folds; 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 ka 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 endliwa vuhumelerisi lebyi yaka emahlweni.

Lapi ra mahiselo yale henhla ya PTFE (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/pharmaceutical sterile, na ti filters ta 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 kahle swinene ka gezi 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), ti conveyors ta swakudya leswi oxiweke, tilayini to kufumeta swilondza, ti tunnel leti titimelaka, ti heat sealers, na roller wrapping. Swi hunguta ku tlanga hi nkarhi na nkarhi wo basisa.

Warp na weft density ya lapi ra fiberglass swi boha matirhelo ya lapi ra mahiselo yale henhla ya PTFE. Density yale henhla yi engetela matimba ya tensile xikan’we naku olova ka le henhla kambe yi hunguta matimba ya tear (inverted U-curve), ku olova, xikan’we naku nghena ka coating. Density leyinene yi ringanisela ku nghena, ku tsandzeka ku handzuka, ku olova, na ku hetisa ehenhla. Density yale hansi yi fambelana na dynamic bending; density yale henhla ya non-stick na insulation.

Calendering – ku tshikelela lapi leri funengetiweke hi PTFE exikarhi ka ti mirror rollers leti hisiweke eka 360-380°C – swi cinca swinene xivumbeko xa le henhla, swivumbeko swa ku humesiwa, ku nga ngheni, na matirhelo ya michini. Yi hunguta ku khwaxa kusuka eka Ra 0.5-1.0 μm kuya eka <0.05 μm, yi pfala ti pinholes, yi antswisa ku tiya ka ku onhaka, kambe yi hunguta matimba yo handzuka xikan’we naku olova. I swa nkoka eka ti release liners na ku pfaleriwa ka gezi.

PTFE lapi ra mahiselo yale henhla na lapi ra silicone hivumbirhi bya swona switirhisa lapi ra fiberglass tani hi xisekelo kambe swihambana hi switirhisiwa swo peta (PTFE resin vs silicone rubber). PTFE yi humelela swinene eka ku nga namarheli, ku lwisana na ku ambala, na ku lwisana na tikhemikhali ku fika eka 260°C. Lapi ra silicone rinyika ku olova lokukulu, ku pfaleriwa ka gezi, na ku tiya ka ndzilo (kufika eka 230°C). Hlawula hi ku ya hi leswi u swi rhangisaka emahlweni.

PTFE lapi ra mahiselo yale henhla (PTFE membrane material) i nhlawulo wa premium eka tensile architecture. Swipfuno swa nkoka: vutomi byale handle bya malembe ya 30+, ndzhawu yo ti basisa (mati ya mpfula ya hlantswa thyaka), ku hundziseriwa ka ku vonakala ko olova (6-13%), Class A fire rating, na matimba yofana na nsimbi ehansi ka 1.5 kg/m2. Yi tirhisiwa eswitediyamu, eswihambukelweni swa swihaha-mpfhuka ni le miakweni leyi nga ni swifaniso emisaveni hinkwayo.

Lapi ra mahiselo yale henhla ra PTFE rinyika ku tiya ka ti khemikhali loku hlawulekeke, ku tiyisela ti acids to tiya, alkalis, ti organic solvents, na tigasi leti onhaka. Xihloko lexi xi hlamusela hi vuxokoxoko swilo swa yona leswi tiyeke, swipimelo (tinsimbi ta alkali leti n’okiweke, swiaki leswi tiyeke swa fluorinating), ni swilo swa nkoka swo tanihi mahiselo, ku hlangana ni ntshikilelo wa michini.
