Switirhisiwa swo hetisa ehenhla leswi cheriweke eka lapi ra fiberglass loko kungase peta PTFE swina nkoka swinene eka matirhelo yohetelela ya lapi ra mahiselo yale henhla ya PTFE. Ti organosilane coupling agents ti endla mabuloho ya molecular exikarhi ka inorganic glass fibre na organic PTFE, leswi tlakusaka matimba ya peel kusuka eka <2 N/cm kuya eka 4-8+ N/cm. Vutshunguri lebyi faneleke byi tlhela byi antswisa ku tiya ka kuhisa (260°C+), matirhelo ya dielectric, na ku tiya ka tikhemikhali. Lapi leri nga tshunguriwangiki ri yisa eka delamination, bubbling, na vutomi byo koma bya ntirho.

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, na ku 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.

Fiberglass weave pattern – plain, twill, kumbe satin – yi khumba swinene swivumbeko swa PTFE swa lapi ra mahiselo yale henhla. Satin weave yinyika matimba yale henhla swinene ya tear (2-3x plain) xikan’we naku olova, leswinga kahle eka dynamic bending. Plain weave yinyika kutshamiseka ka kahle swinene ka dimensional xikan’we naku namarhela ka peel, leswi faneleke eka switirhisiwa swa static. Twill yi ringanisela swivumbeko hinkwaswo leswaku swi tirhisiwa hi ku angarhela.

Kufana ka ku peta ka lapi ra mahiselo yale henhla ya PTFE swikumiwa hi swilo swa mune: ku endliwa ka ku peta (sayizi ya ti particle 0.15-0.35 μm, viscosity, solid content), endlelo ro peta & sintering (ku peta ka blade ku tsakeriwa kuva kufana), khwalithi ya substrate (weave pattern, pre-treatment), na ndzhawu ya vuhumelerisi (20-25°C, <60% RH). Dip + blade combined process yi ringanisela ku nghena na ku olova ka le henhla.

Ku basisiwa loku faneleke na ku hlayisiwa swi engetela vutomi bya lapi ra mahiselo yale henhla ya PTFE. Hlantswa endzhaku ko tirhisa na endzhaku ko titimela. Tirhisa maburashi yo olova, swibasisi leswi nga riki na xihlawuhlawu kumbe byala eka swivati. U nga tshuki u tirhisa ti acid/alkali to tiya, bleach, kumbe swikhwama swa nsimbi. Ku cheriwa ka mafurha ya silicone nkarhi na nkarhi swi hunguta ku onhaka. Landzelela swiletelo leswi ku sivela ku onhaka ka coating.
