Ka nui o ke kala maʻamau o ka PTFE Washer
Nā noi no nā mea holoi PTFE
Sila ʻOihana: He kūpono no ka hoʻopaʻa ʻana i nā sila i loko o nā paipu, nā kiwikā, a me nā ʻōnaehana kaomi kiʻekiʻe.
Nā wahi Kemika a me nā ʻinoʻino: Kūpaʻa i nā kemika ʻino, e hōʻoiaʻiʻo ana i ka lōʻihi a me ka hana.
Nā Lako Hana ʻAi a me nā Lapaʻau: ʻO ka mea PTFE i kūlike me ka FDA e hōʻoiaʻiʻo i nā noi palekana a maʻemaʻe.
Ka Hoʻokaʻawale ʻana o nā Mīkini a me nā Mekanika: Nā mea hoʻokaʻawale hilinaʻi no nā ʻāpana ʻoihana a me nā ʻāpana mechanical.
Nā Papahana ʻenekinia maʻamau: Kūpono no nā koi kūikawā e pono ai nā hoʻonā i hoʻopilikino ʻia.

ʻO ke apo PTFE polytetrafluoroethylene kekahi o nā mea kū'ē maika'i i ka palaho ma ka honua i kēia lā, no laila e ki'i i ka inoa o "mō'ī plastik". Hiki ke ho'ohana 'ia i kekahi 'ano mea kemika no ka manawa lō'ihi, a ua ho'oponopono i nā pilikia he nui i nā kemika, petroleum, lā'au lapa'au a me nā 'oihana 'ē a'e ma ko mākou 'āina. Nā sila Ptfe, gaskets, gaskets. Hana 'ia nā sila Polytetrafluoroethylene, gaskets, sealing gaskets me ka ho'ohehe'e 'ia o ka polytetrafluoroethylene resin.
Nā kūlana hoʻohana o Polytetrafluoroethylene (PTFE) i ka ʻoihana kemika, petrochemical, hoʻomaʻemaʻe, alkali, waikawa, mea hoʻoulu phosphate, lāʻau lapaʻau, pesticide, fiber kemika, dye, coking, kinoea lanahu, synthesis organik, hoʻoheheʻe ʻole-ferrous, kila, ikehu atomika a me nā huahana maʻemaʻe kiʻekiʻe (e laʻa, electrolysis membrane ionic), ka halihali a me ka hana ʻana o nā mea viscous, nā meaʻai olakino koʻikoʻi loa, nā mea inu a me nā keʻena hana ʻē aʻe. ʻO ka waikawa phosphoric waena, ka waikawa sulfuric, ka waikawa nitric, ka waikawa hydrochloric, nā ʻano waikawa organik like ʻole, nā mea hoʻoheheʻe organik, nā oxidants ikaika a me nā mea hoʻoheheʻe kemika corrosive ikaika ʻē aʻe.
Mahana -100~280℃, e ʻae ana i ka hoʻoluʻolu koke a me ka hoʻomehana koke, a i ʻole ke hoʻololi ʻana i ka hana wela a me ke anu.
Kaomi -0.1 ~ 6.4mpa (kaomi piha maikaʻi ʻole i 64kgf/cm2)
-0.1 ~ 6.4mpa (Fullvacuumto64kgf/cm2)
ʻO ke apo paʻa PTFE ka mea nui e hoʻoikaika i ka cylinder, ka ʻōnaehana hydraulic a i ʻole ke kaomi valve me ka ʻole o ka nalowale ʻana i kāna hana sila, hiki ke pale i ka "extrusion" O-ring, hoʻomaikaʻi i kāna hoʻohana ʻana i ke kaomi, a hiki ke hana ʻia kona nui e like me nā koi o ka mea kūʻai aku.
He kūpaʻa ke apo paʻa PTFE i ka mahana kiʻekiʻe -- a hiki i ka mahana hana a hiki i 250℃.
Ke kūpaʻa haʻahaʻa o ke apo PTFE -- me ka paʻakikī mechanical maikaʻi; ʻOiai ke hāʻule ka mahana i -196 ℃, hiki ke mālama ʻia ka elongation 5%.
ʻO ke kūpaʻa ʻana o ke apo PTFE i ka palaho - no ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, e hōʻike ana i ka inert, ka waikawa ikaika a me ka alkali, ka wai a me nā ʻano mea hoʻoheheʻe organik like ʻole.
Ke kūpaʻa ʻana o ke apo PTFE i ke aniau - ka palakiko i ke ola ʻelemakule.
ʻO ke apo PTFE me ka lubrication kiʻekiʻe - he mea paʻa ia i ke koina friction.
ʻAʻole pipili ke apo PTFE -- ʻo ia ka ʻumeke liʻiliʻi loa o ka ʻili i nā mea paʻa a ʻaʻole pipili i kekahi mea.
