He aha kāu ʻike e pili ana i ka PTFE?

He aha ka PTFE?

ʻO Polytetrafluoroethylene (PTFE) kahi ʻano polymer i hoʻohuihui ʻia me ka tetrafluoroethylene e like me ka monomer.Loaʻa iā ia ka wela a me ke anuanu maikaʻi loa a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma ka liʻiliʻi o 180 ~ 260 º C. Aia kēia mea i nā hiʻohiʻona o ka pale ʻana i ka waikawa, ke kūpaʻa alkali a me ke kūʻē ʻana i nā mea hoʻoheheʻe kūlohelohe, a aneane hiki ʻole ke hoʻoheheʻe ʻia i nā solvents a pau.I ka manawa like, loaʻa ka polytetrafluoroethylene i nā ʻano o ke kūpaʻa wela kiʻekiʻe, a ʻoi loa ka haʻahaʻa o kona friction coefficient, no laila hiki ke hoʻohana ʻia no ka lubrication, a lilo hoʻi i kahi uhi kūpono no ka hoʻomaʻemaʻe maʻalahi o ka papa o loko o nā paipu wai.ʻO ka PTFE e pili ana i ka hoʻohui ʻana o ka uhi uhi ʻana o ka PTFE i loko o ka hui ʻōpala EPDM maʻamau, ʻo ia ka mea keʻokeʻo.

ʻO ke kuleana o PTFE

Hiki i ka PTFE ke pale pono i nā hui ʻōpala mai ka waikawa ikaika, ka alkali ikaika a i ʻole ka aila wela kiʻekiʻe a me nā mea ʻino ʻē aʻe.

Ke kumu

• Hoʻohana ʻia ia i ka ʻoihana uila a ma ke ʻano he insulation layer, corrosion resistant a me nā mea ʻaʻahu no ka mana a me nā laina hōʻailona ma ka aerospace, aviation, electronics, instrumentation, computer a me nā ʻoihana ʻē aʻe.Hiki ke hoʻohana ʻia e hana i nā kiʻiʻoniʻoni, nā pepa paipu, nā koʻokoʻo, nā bearings, gaskets, valves, chemical pipes, pipe fittings, equipment container linings, etc.
• Hoʻohana ʻia ia i nā ʻoihana uila, ʻoihana kemika, mokulele, mīkini a me nā ʻano ʻē aʻe e hoʻololi i nā aniani quartz no ka nānā ʻana i nā kemika ultra-pure a me ka mālama ʻana i nā waikawa like ʻole, alkalis a me nā mea hoʻoheheʻe organik i nā kahua o ka ikehu atomic, lāʻau lapaʻau, semiconductor. a me nā ʻoihana ʻē aʻe.Hiki ke hana ia i mau ʻāpana uila insulation kiʻekiʻe, uea alapine kiʻekiʻe a me nā sheaths cable, corrosion resistant chemical utensils, kiʻekiʻe wela kū'ē i ka aila paipu, artificial organs, etc. nā momona, etc.
• He kū'ē ka PTFE i ka wela kiʻekiʻe a me ka corrosion, loaʻa ka insulation uila maikaʻi loa, ke kūpaʻa ʻelemakule, ka haʻahaʻa haʻahaʻa o ka wai, a me ka maikaʻi o ka lubrication ponoʻī.ʻO ia ka pauka lubricating āpau i kūpono no nā media like ʻole, a hiki ke hoʻopili koke ʻia e hana i kahi kiʻi maloʻo, hiki ke hoʻohana ʻia ma ke ʻano he graphite, molybdenum a me nā lubricants inorganic ʻē aʻe.He mea hoʻokuʻu kūpono ia no nā polymers thermoplastic a me thermosetting, me ka hiki ke lawe maikaʻi.Hoʻohana nui ʻia ia i ka ʻoihana elastomer a me ka ʻoihana a me ka pale ʻana i ka corrosion.
• Ma ke ʻano he mea hoʻopihapiha no ka epoxy resin, hiki iā ia ke hoʻomaikaʻi i ka pale ʻana i ka abrasion, ka pale wela a me ka pale ʻana o ka epoxy adhesive.
• Hoʻohana nui ʻia e like me ka binder a me ka hoʻopiha ʻana i ka pauka.

Nā pono o ka PTFE

• Palena wela kiʻekiʻe - ka wela hana a hiki i 250 ℃
• ʻO ke kūpaʻa haʻahaʻa haʻahaʻa - ka paʻakikī mechanical maikaʻi;ʻOiai ke hāʻule ka mahana i -196 ℃, hiki ke mālama ʻia ka elongation o 5%.
• Ka pale ʻana i ka corrosion - no ka hapa nui o nā kemika a me nā mea hoʻoheheʻe, ʻaʻole inert a kūpaʻa i nā ʻakika ikaika a me nā alkalis, ka wai a me nā mea hoʻoheheʻe kūlohelohe.
• Kūleʻa i ka wā - loaʻa ka ola kahiko maikaʻi loa o nā plastic.
• ʻO ka lubrication kiʻekiʻe ka helu haʻahaʻa haʻahaʻa ma waena o nā mea paʻa.
• Non-adhesion - ʻo ia ka haʻahaʻa haʻahaʻa haʻahaʻa i loko o nā mea paʻa a ʻaʻole pili i kekahi mea.
• Non-toxic - He physiological inertia, a ʻaʻohe hopena ʻino ma hope o ka hoʻokomo ʻana i ka wā lōʻihi e like me nā kīʻaha koko a me nā ʻāpana.
• ʻO ka hoʻokuʻu uila - hiki ke kū i ka 1500 V kiʻekiʻe voltage.
