1. Ƙananan sojojin yanke.Saboda taurin, ƙarfi, da taurin PTFE da ke ƙasa, ƙarƙashin yanayin yanke iri ɗaya, babban ƙarfin yanke 45 karfe shine sau 14-20 nawasan tseren fimAbubuwan da aka bayar na PTFE.
2. Fim din PTFE yana da ƙananan ƙarancin thermal, kawai 0.27W / MK-1, tare da ƙananan zafin jiki mai zafi, babban zafin jiki mai zafi shine kawai 250 ℃.Idan fim ɗin skiving girma ya yi girma, saurin yanke yana da girma, kuma yankan zafin jiki na aikin aikin zai tashi, wanda zai yi laushi da kayan PTFE, har ma narke, coking, da "wuka mai tsayi" sabon abu.Kafin aiwatar da yankan, an warke blank tare da yanayin tsari na digiri 30-50 na Celsius sama da zafin aiki da lokacin warkewa na 24h ko fiye, don tabbatar da daidaiton girman tsarin wasan tseren fim.
3.
