He aha ka PTFE gaskets

ʻO nā Sila a pau he mea hoʻololi alakaʻi nui o nā gaskets PTFE kiʻekiʻe, nā sila, nā mea holoi a me nā insulators.

Loaʻa i nā Sila a pau ka ʻike i ka hāʻawi ʻana i nā gaskets PTFE pololei, nā sila, nā mea holoi, a me nā insulators no kahi ākea o nā ʻoihana a me nā noi.ʻO Polytetrafluoroethylene (PTFE) ka inoa inoa o ka polymer a DuPont.He fluoropolymer synthetic ia o ka tetrafluoroethylene me ke kalapona a me ka fluorine.He hydrophobic maoli ia (ka hoʻihoʻi ʻana i ka wai a me ka wai i loko o nā mea) a loaʻa iā ia kekahi o nā coefficient haʻahaʻa haʻahaʻa o ka friction e kūʻē i kekahi paʻa.

Loaʻa i ka PTFE nā waiwai dielectric maikaʻi loa a hāʻawi i ka insulation thermal maikaʻi loa me ka pae wela hana o -400°F a 500°F.ʻO ka PTFE ka mea i ʻike ʻia a ʻike ʻole ʻia e ka nui o nā wai corrosive, nā mahu, a me nā kinoea.Hāʻawi ʻia ʻo PTFE ma nā mānoanoa mai .002 ″ a i .250 ″ mānoanoa a kūlike i nā kikoʻī FDA a me AMS, e ʻae ʻia i nā ʻoihana lapaʻau a me nā ʻoihana meaʻai.

PTFE, polimer piha ʻole Nā ʻaʻahu

Hana ʻia nā gaskets PTFE wahine mai ka 100% mea maʻemaʻe i hoʻohana ʻia i nā noi maʻamau.He palupalu loa a hiki ke hoʻohana ʻia a hoʻohana pinepine ʻia no nā sila kūpaʻa kemika a me nā gaskets.Hana pololei ia mai ka mea hana resin a ʻaʻole i hana ʻia i ke ʻano.Loaʻa iā ia nā waiwai insulation kino kiʻekiʻe a me ka uila a ua hoʻonui i ke kū'ē i ka kolo (kaomi) ma lalo o ka ukana.Hiki ke ʻike ʻia ka PTFE mānoanoa e kona kala keʻokeʻo ke hoʻohālikelike ʻia me ka PTFE mechanical grade.

PTFE, PihapolimerNā ʻaʻahu

Hoʻopiha ʻia nā gaskets PTFE mai PTFE e hoʻohui i nā mea hoʻohui a me nā mea hoʻopihapiha i mea e hoʻomaikaʻi ai i ka hana o ka gasket.Hoʻonui kēia i ka hiki ke ʻaʻahu a hoʻonui i kāna hui kūʻokoʻa o nā waiwai kemika, kino a me nā uila.ʻO ka polymer piha ka ʻano maʻamau o ka gasket PTFE no ka hoʻohana ʻana i ka ʻoihana no ka mea e hōʻike ana i ka ikaika mechanical i hoʻohālikelike ʻia me Virgin PTFE.ʻO ke aniani, carbon a me ka fiber particles nā mea hoʻopihapiha maʻamau i hoʻohana ʻia e hoʻonui i ka ikaika mechanical o ka gasket ma muli o ka noi.

PTFE, HoʻonuipolimerNā ʻaʻahu

Hoʻopuka ʻia nā mea gasket PTFE i hoʻonui ʻia e ka hoʻonui ʻana i ka PTFE Virgin me ka hoʻohana ʻana i kahi kaʻina hana e hana i kahi microstructure like ʻole a fibrillated loa me ka ikaika tensile like ma nā ʻaoʻao āpau.ʻO ia hoʻi, ʻaʻohe nāwaliwali o ke kūkulu ʻana a i ʻole ka "palaoa".No ka mea ʻaʻole koi ʻia nā mea hoʻohui, loaʻa pū ka polymer hoʻonui i ke kū kūʻokoʻa kūʻokoʻa o ka polymer Virgin.ʻOi aku ka palupalu a ʻoi aku ka maʻalahi o ka PTFE i hoʻonui ʻia ma mua o nā gaskets PTFE maʻamau a no laila e hoʻohālikelike maʻalahi i nā ʻaoʻao ʻokoʻa a me nā mea ʻala.ʻOi aku ka maʻalahi o ka hoʻopili ʻana a hoʻemi i ka kolo a me ke kahe anuanu.
