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 parenga teitei o te pāmahana, te pai o te waikawa me te alkali parenga me te hinu hinu; me te pai o te rebound, 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 o te 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, ki te whakataurite 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%

Kei te ngakau o te hiranga o to tatou hua ko tona hanganga rauemi ahurei. Ko te PTFE, he mea rongonui mo te kaha o te atete matū me te iti o te waku, i honoa ki te elasticity me te mau atete o te EPDM, ka hangaia he otinga hiri e kore e rite ki tona kaha ki te pupuri i te pono me te mahi puta noa i te whānuitanga o nga tono. Mai i te DN50 ki te DN600 te rahi o te tauranga, he mea hanga to tatou riipene rewharewha a Teflon kia pai ai te uru ki roto ki nga hononga angiangi, flange ranei-whakamutunga, ka waiho hei whiringa pai mo nga umanga penei i te kakano, te teihana hiko, te petrochemical, te whakamahana me te whakamahana, te rongoa, te hanga kaipuke, te whakarewa. , ahumahi marama, me te tiaki taiao.Ko te hoahoa o to tatou Teflon Butterfly Valve Liner e arotahi ana ki te ngawari o te whakaurunga me te tiaki, e whai ana ki te whakaiti i te wa heke me te whakanui ake i te pai. Ahakoa kei te whakatinanahia e koe he momo angiangi te riipene riipene hiri hiri ngawari, he reera rewharewha angiangi pneumatic ranei, ka whakamanahia e a maatau hua he hiri tino pai i nga wa katoa, me te whakaiti i te tupono o nga turuturu ka raru te whakahaere me te utu utu. I tua atu, ko te kore o te titi i roto i a maatau momo lug e rua haurua haurua rewharewha rewharewha ka whakarite kia pai ake te mahi me te whakanui ake i te roanga o te puera. Ma te aro ki nga rauemi teitei-kounga me te mahi miihini tika, ko te Sansheng Fluorine Plastics Teflon Butterfly Valve Liner e tu ana hei tohu mo te auahatanga me te hiranga i roto i nga otinga hiri a-ahumahi.
