Polytetrafluoroethene,pōkole:PTFE
ʻAi kapa ʻia: PTFE, tetrafluoroethylene, mōʻī plastik, F4.
Nā Pōmaikaʻi o ka PTFE
PTFEʻO nā plastik ʻenekinia kūikawā, i kēia manawa nā mea pale i ka corrosion, i ʻike ʻia ʻo "plastic mōʻī". ʻO nā hiʻohiʻona nui ke kūpaʻa wela kiʻekiʻe a me ka haʻahaʻa, ke kūpaʻa i ka corrosion, ka insulation kiʻekiʻe, ke kūpaʻa ʻelemakule, a me ka lubrication ponoʻī.
Hoʻohana ʻia ia i loko o ka aerospace, nā mea uila a me nā lako uila, ka ʻoihana kemika, nā mīkini a me nā mea kani, ka meaʻai a me nā lāʻau lapaʻau, nā pamu, nā valves a me nā pipelines, nā kaʻa a me nā moku, nā compressors air, a ua lilo ia i mea pono ʻole no ka hoʻoponopono ʻana i nā ʻenehana koʻikoʻi he nui i ka ʻoihana hou.
ʻO ka molekala PTFE inert F atoms e pale ana a pale i ka pilina CC, a ʻo ka ikehu hoʻopili CF he paʻa loa ia, he paʻakikī ke luku ʻia ke kaulahao molekala, he ʻano paʻa loa ia. Ho'ākāka pū kēia ʻano molekala i nā waiwai maikaʻi loa o ka PTFE.
Ke kū'ē'ē i ka palaho:Ma waho aʻe o nā metala alkali i hoʻoheheʻe ʻia a me kekahi mau mea hoʻoheheʻe e like me nā hydrocarbons alkane āpau ma luna o 300 degere Celsius, kū ia i ka pala lōʻihi e nā kemika ʻē aʻe.
Ke kū'ē nei i nā mahana kiʻekiʻe a me ka haʻahaʻa: hiki ke hoʻohana ʻia no ka manawa lōʻihi ma -60 + 260 ℃.
Lubrication kiʻekiʻe:ʻo ke koina haʻalulu liʻiliʻi loa ma waena o nā mea paʻa, ʻaʻole hiki i ka hau ke hoʻohālikelike me ia.
ʻAʻole hoʻopili:ʻo ka ʻilikai liʻiliʻi loa i waena o nā mea paʻa, ʻaʻole ia e pipili i kekahi mea.
Ke kū'ē ʻana i ke aniau:ʻO ke ola lōʻihi loa i waena o nā plastik.
ʻAʻohe ʻawahia:hiki ke hoʻohana ʻia ka mea ma ke ʻano he mau kīʻaha koko hana, ʻaʻohe mea ʻawahia a ʻaʻole hoʻi e pili ana i ka maʻi a me nā hopena ʻino ʻē aʻe, no nā meaʻai a me nā lāʻau lapaʻau.
Nā waiwai hoʻokaʻawale:ʻO kahi kiʻiʻoniʻoni mānoanoa e like me ka nūpepa ua lawa ia e kū'ē i ka uila voltage kiʻekiʻe o 1500V.
Eia kekahi, ʻaʻohe omo wai o ka PTFE, ʻaʻole hiki ke lapalapa, a paʻa loa i ka oxygen a me ka mālamalama ultraviolet.
Nā hemahema o ka PTFE
ʻOiai ʻo PTFE ka hana piha maikaʻi loa, akā he haʻahaʻa ka ikaika mechanical, nui ka coefficient o ka hoʻonui linear, ʻilihune ke kū'ē ʻana i ka ʻaʻahu, ʻilihune ke kū'ē ʻana i ka kolo, ʻilihune ka conductivity thermal a me nā hemahema ʻē aʻe. I ka ikaika mechanical a me nā kūlana paʻakikī ʻē aʻe, e like me ka hoʻohana ʻia ʻana i ka ʻoihana sila valve a me kona palena maoli o ka hoʻohana palekana ʻana o ka mahana ma waena o -70 ~ +150 ℃. I mea e lanakila ai i kēia mau hemahema, hiki ke hoʻopiha ʻia ka resin PTFE me nā mea hoʻoikaika e hoʻomaikaʻi i nā waiwai mechanical o ka mea, i mea e hoʻonui ai i ka laulā o ka hoʻohana ʻana o kāna mau mea.
Hoʻolauna i nā waiwai o ka PTFE kala
ʻO ke kala mua o ka PTFE he keʻokeʻo waiū, ʻoiai ʻo ka PTFE kala no ka mea ua piha ka mea kumu PTFE me nā mea kōkua. Hiki ke hoʻokaʻawale ʻia nā mea kōkua i ʻelua mau ʻāpana e like me ka hoʻohana ʻana: ka mea hoʻonui a me ka mea pauka kala.
Papa ʻākena pauka kala: ua piha i ka pauka kala i loko o ka PTFE, hiki ke ʻeleʻele, melemele, ʻulaʻula, ʻōmaʻomaʻo, uliuli a pēlā aku. ʻO ka ʻākena pauka kala wale nō ke hoʻololi i ke kala o ka PTFE, he liʻiliʻi ka lakio o ka mea hoʻopihapiha no laila hiki ke hoʻowahāwahā ʻia ka hopena o ka hana mua o ka PTFE. Ma ke kumumanaʻo, pono e hiki i ka ʻākena pauka kala ke hoʻopilikia i ke kūpaʻa kemika o ka PTFE, ka insulation, ka ikaika tensile a me nā waiwai mechanical ʻē aʻe. No laila, pono e hoʻomaopopo i kekahi mau hanana kūikawā. Hoʻokō ka PTFE kala i nā koi o nā mea kūʻai aku e loaʻa ana nā koi no nā kala ʻike.
ʻAʻole wale ke koho ʻana i nā kikoʻī like ʻole no nā noi like ʻole ke kūʻai ʻana i ka paipu PTFE kūpono. ʻOi aku ka nui o ke koho ʻana i kahi mea hana hilinaʻi.ʻO BesteflonHe loea ʻo Fluorine plastic Industry Co., Ltd. i ka hana ʻana i nā mea kiʻekiʻe kiʻekiʻeNā hose PTFEa me nā paipu no 20 mau makahiki. Inā he mau nīnau a me nā pono o ka paipu ptfe, e ʻoluʻolu e nīnau mai iā mākou no ka ʻōlelo aʻoaʻo loea hou aku.
