Pango/Kakariki PTFE/ FPM +EPDM Rubber Valve Seat mo Butterfly Valve Seat
Ko te PTFE + EPDM ko nga tuuru rapa rapa i hangaia e te SML e whakamahia nuitia ana i roto i te pueru, te teihana hiko, te petrochemical, te whakamahana me te whakamatao, te rongoa, te hanga kaipuke, te whakarewa, te ahumahi marama, te tiaki taiao me etahi atu mara.
Te mahi hua: te kaha o te pāmahana teitei, te pai o te waikawa me te alkali parenga me te hinu hinu; me te pai o te reanga, te pakari me te mau tonu me te kore e pakaru.
PTFE+EPDM
Ko te raina Teflon (PTFE) ka whakakikorua i te EPDM kua herea ki tetahi mowhiti phenolic maataki i te paenga nohoanga o waho. Ka toro atu te PTFE ki runga i nga kanohi o te nohoanga me te taha o waho o te hiri hiri, ka kapi katoa i te paparanga elastomer EPDM o te nohoanga, e whakarato ana i te kaha mo te hiri i nga kakau takirere me te kōpae kati.
Awhe pāmahana: -10°C ki te 150°C.
Wahine PTFE (Polytetrafluoroethylene)
Ko te PTFE (Teflon) he waerau e hangai ana ki te fluorocarbon me te tikanga ko te tino matū atete o nga kirihou katoa, me te pupuri i nga waahanga whakamaarama wera me te hiko. He iti te whakarea waku o te PTFE na reira he pai mo te maha o nga tono taipana iti.
Ko tenei rauemi kaore i te poke, ka whakaaetia e te FDA mo nga tono kai. Ahakoa he iti nga ahuatanga miihini o te PTFE, ka whakatauritea ki etahi atu kirihou kua hangaia, ka whai hua tonu ona taonga mo te whānuitanga o te pāmahana.
Awhe pāmahana: -38°C ki te +230°C.
Tae: ma
Apiti taipana: 0%
