ʻEleʻele/ Green PTFE/ FPM + EPDM Rubber Valve Noho no Butterfly Valve Noho
ʻO ka PTFE + EPDM hui pū ʻia nā pahu valve i hana ʻia e SML e hoʻohana nui ʻia i ka textile, ka mana mana, ka petrochemical, ka wela a me ka refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection and other field.
ʻO ka hana huahana: ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa maikaʻi o ka waikawa a me ka alkali a me ka pale ʻaila; me ka hoʻihoʻi maikaʻi ʻana, paʻa a paʻa me ka ʻole o ka hū.
PTFE+EPDM
Hoʻopili ka liner Teflon (PTFE) i ka EPDM i hoʻopaʻa ʻia i kahi apo phenolic paʻa ma ka ʻaoʻao o ka noho waho. Hoʻonui ka PTFE ma luna o nā alo noho a ma waho o ke anawaena flange seal, e uhi piha ana i ka papa elastomer EPDM o ka noho, e hāʻawi ana i ke kūpaʻa no ka hoʻopaʻa ʻana i nā ʻōpala valve a me ka disc pani.
Kaulana wela: -10°C a i 150°C.
PTFE wahine (Polytetrafluoroethylene)
ʻO ka PTFE (Teflon) he polymer i hoʻokumu ʻia i ka fluorocarbon a ʻo ka mea maʻamau ʻo ia ka mea kūʻokoʻa kemika o nā plastics āpau, ʻoiai e paʻa ana i nā waiwai insulation wela a me ka uila. He haʻahaʻa haʻahaʻa haʻahaʻa o ka friction ka PTFE no laila he kūpono ia no nā noi torque haʻahaʻa.
ʻAʻole hoʻohaumia kēia mea a ʻae ʻia e ka FDA no nā noi meaʻai. ʻOiai he haʻahaʻa nā waiwai mechanical o PTFE, ke hoʻohālikelike ʻia me nā plastics engineered ʻē aʻe, e mau ana kāna mau waiwai ma luna o kahi ākea ākea.
Kaulana wela: -38°C a i +230°C.
