Hoʻolālā kūikawā ʻia nā kaula Poly Tetra Fluoro Ethylene a i ʻole PTFE no nā noi koʻikoʻi no ka mea he mea kemika maikaʻi loa, ka wai, ka mahana, a me nā pale uila.Ua ʻike ʻia kēia mau uwea i kona hoʻohana ʻana ma nā hoʻonohonoho ʻoihana a me nā hale noho.Nui nā ʻano o nā uwea PTFE i loaʻa ma ka mākeke e like me nā uea lako PTFE, nā uea PTFE multi-core, ka uku a me ka hoʻonui ʻia (nā kaula thermocouple), nā lima uila PTFE, nā uea wela PTFE, nā kaula uila kiʻekiʻe PTFE a me nā mea ʻē aʻe.Hoʻomaopopo ʻia nā kaula i hana ʻia me ka PTFE no ko lākou lōʻihi, hiki ke maʻalahi, a me ka hilinaʻi.Mahalo ʻia kēia mau mea no ko lākou mau haʻahaʻa haʻahaʻa haʻahaʻa a me nā ʻano pale ahi.E heluhelu no ka ʻike i nā kikoʻī o kēia uwea paʻa.
ʻO nā pono o nā kaula PTFE
ʻO kaPTFEhiki i nā uwea insulated a me nā kaula ke hoʻomanawanui i kahi kiʻekiʻe o ka wela e hoʻomaka ana mai (-) 60º C a (+) 260 ºC.Ma muli o ka hiki ʻole o kēia mau uea i ka wela a me ka pale ʻole i ka wā, ua hoʻohana ʻia kēia mau mea ma nā wahi he nui e like me nā hōkele, nā hale ʻaina, nā halemai, nā lumi kamepiula, nā hale kiʻekiʻe, nā hale kiʻiʻoniʻoni, nā lumi hōʻikeʻike a me nā mea ʻē aʻe.Hoʻolālā kūikawā ʻia kēia mau kaula e hana i nā haʻahaʻa kiʻekiʻe o kēia manawa i ke kaiapuni kiʻekiʻe, kahi e kūpono ai a palekana hoʻi i ka hoʻohana ʻana i nā umu, nā uwila ʻoihana, etc.
Noi o na Uula PTFE
He kūpono nā kaula PTFE no ka hāʻawi ʻana i ka pale a me ka uhi ʻana i nā mea lapaʻau no ka mea hiki iā lākou ke kūpaʻa i nā kūlana ākea.ʻO nā wela kiʻekiʻe, friction a me nā kemika corrosive kekahi o nā kūlana i kū pinepine ʻia e kahi uea kaʻa.No laila, pono ia i ka palekana i hāʻawi ʻia e nā mea PTFE.Hoʻohana nui ʻia kēia mau kaula i ka hoʻokele mana, nā noho wela, ka ea, nā noi pākaukau a me nā mea ʻē aʻe.Manaʻo ʻia ʻo ia kekahi o nā insulators maikaʻi loa, hoʻohana nui ʻia kēia mau uea i nā ʻāpana uila a puni ka honua.Hiki i kēia mau kaula ke hoʻokaʻawale i ka 500 volts i ka mil, kahi e hilinaʻi ai lākou no nā noi koʻikoʻi.ʻO nā kamepiula, bioengineering, robotics, ʻepekema kemika kekahi o nā wahi noi ʻē aʻe o nā kaula PTFE.
No ke aha e pono ai ka PTFE?
ʻO ka PTFE kahi mea uhi i loaʻa nā pono he nui.Ma ke ʻano he insulator, ua manaʻo ʻia he mea maikaʻi loa ia ma muli o kāna mau paʻa carbon-fluorine, kahi e hiki ai ke maʻalahi a ʻaʻole hoʻi.He hydrophobic hoʻi ka mea e hoʻoneʻe ʻole ai i ka wai.ʻO nā mea kemika o nā uea PTFE e hōʻoia i ko lākou maʻalahi, kūlou, a me ke koʻikoʻi.He kūpono hoʻi kēia mau uea no ka laulā ākea.Hāʻawi lākou i nā pono mālama wahi ma mua o nā insulators liʻiliʻi ʻē aʻe.Ma waho aʻe o kēia mau mea a pau, haʻahaʻa haʻahaʻa haʻahaʻa, ikaika dielectric kiʻekiʻe, kiʻekiʻe o ka hana wela, kū'ē i ka radiation UV a me nā mea ʻē aʻe e hana ai i ka PTFE i koho kūpono no nā noi lōʻihi.
ʻO ke ʻano o ka fluorocarbon o nā kaula PTFE he koho hilinaʻi ia no nā noi like ʻole, inā he hale noho, ʻoihana a ʻoihana paha.Ma waho aʻe o kēia, ʻo ka inertness kemika ʻokoʻa, ke kūpaʻa wela maikaʻi loa a me nā waiwai uila i hoʻohālikelike ʻia i kēia mau kaula i kūpono no nā noi he nui.I kēia mau lā, ke komo nei nā hui he nui i ka hoʻolako ʻana i nā kaula PTFE.Inā makemake ʻoe e ʻimi i nā mea kūʻai aku ʻo PTFE Cables ma kou wahi, a laila ʻo ka ʻimi pūnaewele ke koho maikaʻi loa.
