Whakamahi Hua
Ka whakamahia nuitia mo te hanga horoi, pereti, O-mowhiti, V-mowhiti, hiri hinu, diaphragms, paipa rapa, taura taura, kakahu whakamaarama wera, pereti takirere, hononga roha, roera rapa, paninga me nga putties whakangao i te pāmahana ruuma i nga wa e whakakeke ana. teitei te pāmahana, te wahie( te wahie aunoa), te hinu whakahinuhinu (hinu waihanga), te wai (he momo whakarewa kore-polar) te waikura (waikawa, te alkali), te oxidizer kaha (oleum), te ozone, te radiation me te huarere.
Te aro
1. He pai te pumau o te wera o te FKM i raro i te 200 ℃. Ka whakaputa i te tohu pirau mena ka tukuna ki te 200-300 ℃ mo te wa roa, a ka tere tona tere pirau ki runga ake i te 320 ℃, ko te nuinga o nga hua whakangao he hauwai fluoride paitini me te fluorocarbon organic pūhui.Ka tutaki te rapa pukoro mata ki te ahi, ka tukuna e ia te hauwai hauwai paitini me te puhui orokarbon fluorocarbon.
2. Kare e taea te whakauru te FKM ki te paura konganuku penei i te paura konumohe me te paura konupora, neke atu ranei i te 10% te pūhui amine, ki te tupu tera, ka piki ake te pāmahana, ka tauhohe etahi huānga ki te FKM, ka kino nga taputapu me nga kaiwhakahaere.
Mōkī, Te Waka me te Rokiroki
1.Ko te FKM te whakakii i nga peeke kirihou PE, katahi ka utaina ki nga kaata, ko te taumaha o ia kaata he 20kg.
2.Kei te rongoa te FKM i roto i te whare putunga ma, maroke me te hauhautanga.Ka haria kia rite ki nga matū kore-morearea, me noho mawehe atu i te puna parahanga, te ra me te wai i te wa e kawe ana.
