Zero Leakage PTFE Valve Seat Butterfly Valve Parts DN50 - DN600
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 mālama ana i nā waiwai insulation wela a me ka uila. He haʻahaʻa haʻahaʻa haʻahaʻa o ka friction ka PTFE no laila kūpono ia no nā noi haʻahaʻa 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 kona mau waiwai ma luna o kahi ākea ākea.
Kaulana wela: -38°C a i +230°C.

ʻO ka PTFE no PolyTetraFluoroEthylene, ʻo ia ka huaʻōlelo kemika no ka polymer (CF2)n.
ʻO Polytetrafluoroethylene (PTFE) he lālā thermoplastic o ka ʻohana fluoropolymer o nā plastics a he haʻahaʻa haʻahaʻa o ka friction, nā waiwai insulating maikaʻi loa.
ʻAʻole kemika ʻo PTFE i ka hapa nui o nā mea. Hiki iā ia ke pale i nā noi wela kiʻekiʻe a ua ʻike maikaʻi ʻia no kāna mau waiwai anti-stick.
ʻO ke koho ʻana i ke apo noho kūpono ka mea paʻakikī loa Pahu kinipopo Koho. No ke kōkua ʻana i kā mākou mea kūʻai aku i kēia kaʻina hana, ua mākaukau mākou e hāʻawi i ka ʻike e pili ana i ka noi o ka mea kūʻai aku.
ʻO nā noho valve PTFE i hana ʻia e US ua hoʻohana nui ʻia i ka textile, ka mana mana, ka petrochemical, ka wela a me ka refrigeration, pharmaceutical, shipbuilding, metallurgy, light industry, environmental protection, Paper Industry, Sugar Industry, Compressed Air a me nā māla ʻē aʻe.
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 rebound resilience maikaʻi, paʻa a paʻa ʻole me ka ʻole e kahe.
