Ku omisiwa kahle ka lapi ra fiberglass swina nkoka swinene eka PTFE coating leyi landzelaka, resin impregnation, kumbe lamination. Vutshunguri byinharhu lebyikulu: ku susa ndzhongho eka 105-120°C (10-30 min kuya hi ntiko), dewaxing/thermal cleaning eka 300-450°C (LOI <0.1%, papalata>500°C), naku hisa ka ha ri emahlweni eka 60-100°C loko kungase peta. Lawula kufana ka mahiselo ya oven (±5°C), ku sindzisiwa ku susa ndzhongho, naswona sirhelela malapi lawa ya tshunguriweke hi silane ehansi ka 110°C. Hlayisa lapi leri omisiweke eka minkwama leyi pfaleriweke kumbe makamara yo oma (<30°C, <40% RH).

PTFE lapi ra mahiselo yale henhla (PTFE-coated fiberglass) rinyika swipfuno swa mune swa nkoka tani hi anti-corrosion lining: ku nga tirhi ka tikhemikhali (ku lwisana na aqua regia, ti alkalis to tiya, ti solvents), mahiselo yo anama (-70°C kuya eka 260°C kuya emahlweni, 350°C peak), ku tiya ka dimensional (<0.5% elongation), na vuandlalo lebyi nga namarheliki (ku olova ku basisa, swi sivela ku hlengeletana). Yi tirhisiwa eka tiphayiphi ta tikhemikhali, swihondzo swo susa sulphur, mathangi yo pickling, na switirhisiwa swa swakudya/pharma. Tigredi ta FDA ta kumeka.

PTFE lapi ra mahiselo yale henhla rinyika swipfuno swa tsevu swa nkoka tani hi bandi ro fambisa ro gandlisa: vuandlalo lebyi nga namarheli (ku kandziyisa paste na inki ku humesiwa hiku basa), 260°C ku lwisana na kuhisa (ku omisiwa kahle), ku tiya ka dimensional (<0.5% elongation, ku tsarisiwa loku kongomeke), ku nga tirhi ka tikhemikhali (ku lwisana na ti paste leti bolaka), ku hlangana ka le hansi (ku tirha hi ndlela yo olova), na ku cinciwa (ku tiya,, mihlovo anti-static). Yi kahle swinene eka ku kandziyisa hi xikirini, ku kandziyisa hi xidijitali, na switirhisiwa swo hundzisela ku hisa.

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 mahiselo yale henhla ra PTFE ritshamisekile kuya fika eka 300°C, kambe eka ndzilo ri bola naswona ri humesa tigasi letingana chefu swinene: hydrogen fluoride (HF) (corrosive, pulmonary edema) na perfluoroisobutylene (PFIB) (leyi nga riki na muhlovo, yingari na nun’hwelo, ~10x leyingana chefu kutlula phosgene, kungari na antidote). Nakambe khaboni monokisayidi, masalela ya PFOA, na ti trace dioxins. Swisirhelelo leswi tolovelekeke swa musi a swi tirhi; tirhisa switirhisiwa swo hefemula leswi tiyimeleke (SCBA). Swikombiso swi nga ha hlwela.

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 to 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 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 va ni 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.
