Xihloko lexi xi katsa ndlela yo fambisana na rivilo ra layini ya muchini wo peta na ku leha ka oven ku tiyisisa leswaku xinamarheti xa organosilicone xi fikelela mpimo wa ku horisa lowu kongomisiweke eka thepi ya PTFE ya mahiselo ya le henhla. Nsinya wa nawu wo fambelanisa wa nkoka: nkarhi hinkwawo wo tshama t_total = ku leha ka oveni loku tirhaka L ÷ rivilo ra layini v a ri fanelanga ku va ehansi ka nkarhi wa le hansi lowu lavekaka wo horisa. Kuma swihlawulekisi swa ku horisa hi ku tirhisa DSC kumbe swikambelo swa ku horisa hi ku namarhela leswi simekaka vuxaka bya 'temperature — minimum cure time'.
