Polytetrafluoroethene,pōkole:PTFE
Alias: PTFE, tetrafluoroethylene, mō'ī plastik, F4.
Nā pono o ka PTFE
PTFEʻO ia ka ʻenehana loea kūikawā, i kēia manawa ʻo nā mea pale-corrosion, i kapa ʻia ʻo "plastic king".ʻO nā hiʻohiʻona nui ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ka pale ʻana i ka corrosion, ka insulation kiʻekiʻe, ke kūpaʻa ʻelemakule, ka lubrication ponoʻī.
Hoʻohana ʻia ia i ka aerospace, electronics a me nā mea uila, ʻoihana kemika, mīkini a me nā mea hana, meaʻai a me nā lāʻau lapaʻau, nā ʻōpala, nā valves a me nā pipelines, nā kaʻa a me nā moku, nā ea compressors, etc. ʻoihana.
ʻO ka mole PTFE inert F nā mana e pale a pale i ka paʻa CC, a ʻoi aku ka paʻa o ka ikehu hoʻopaʻa CF, paʻakikī ke hoʻopau ʻia ke kaulahao mole, he hale paʻa loa.Ke wehewehe nei kēia ʻano molekala i nā waiwai maikaʻi loa o PTFE.
ʻO ke kūpaʻa ʻino:Ma waho aʻe o nā metala alkali i hoʻoheheʻe ʻia a me kekahi mau mea hoʻoheheʻe e like me ka all-alkane hydrocarbons ma luna o 300 degere Celsius, ua kūpaʻa ʻo ia i ka corrosion lōʻihi e nā kemika ʻē aʻe.
Ke kū'ē i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa: hiki ke hoʻohana no ka manawa lōʻihi ma -60 + 260 ℃.
Lubrication kiʻekiʻe:ʻo ka helu liʻiliʻi loa o ka friction ma waena o nā mea paʻa, ʻaʻole hiki ke hoʻohālikelike i ka hau.
Hoʻopili ʻole:ʻo ka haʻalulu liʻiliʻi loa ma waena o nā mea paʻa, ʻaʻole pili i kekahi mea.
Kūleʻa Lewa:ʻO ke ola kahiko loa ma waena o nā plastics.
ʻAʻohe mea ʻawaʻawa:hiki ke hoʻohana ʻia ka mea e like me nā kīʻaha koko artificial, non-toxic a non-allergic a me nā hopena ʻino ʻē aʻe, no ka meaʻai a me nā mea lāʻau lapaʻau.
Nā waiwai hoʻokaʻawale:ʻO kahi kiʻiʻoniʻoni e like me ka nūpepa ua lawa ia e pale i ka uila uila kiʻekiʻe o 1500V.
Eia kekahi, ʻaʻohe o ka hoʻoheheʻe ʻana o ka PTFE, non-flammability, a ʻoi loa i ka oxygen, kukui ultraviolet.
Nā hemahema o ka PTFE
ʻOiai he maikaʻi loa ka PTFE, akā haʻahaʻa haʻahaʻa ka ikaika mechanical, coefficient nui o ka hoʻonui ʻana i ka laina, ke kūpaʻa ʻino ʻole, ke kūpaʻa ʻino ʻole, ka conductivity thermal maikaʻi ʻole a me nā hemahema ʻē aʻe.I ka ikaika mechanical a me nā kūlana paʻakikī ʻē aʻe, e like me ka hoʻohana ʻana i ka ʻoihana sealing valve a me kāna palena maoli o ka hoʻohana palekana ʻana i ka mahana ma loko 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 ʻano mechanical o ka mea, i mea e hoʻonui ai i ke ʻano o ka noi ʻana o kāna mau mea.
Hoʻolauna i nā waiwai o ka PTFE kala
ʻO ka waihoʻoluʻu kumu o PTFE he keʻokeʻo keʻokeʻo, ʻoiai ʻo PTFE kala no ka mea ua hoʻopiha ʻia ka waihona 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 pauka kala.
ʻO ka papa ʻaina pauka kala: hoʻopiha ʻia me ka pauka kala i PTFE, hiki ke ʻeleʻele, melemele, ʻulaʻula, ʻōmaʻomaʻo, uliuli a pēlā aku.Hoʻololi wale ka ʻāpana kala kala i ke kala o PTFE, ʻo ka ratio o ka mea hoʻopihapiha he mea liʻiliʻi no laila hiki ke nānā ʻole ʻia ka hopena o ka hana mua o PTFE.ʻO ka manaʻo, pono e hiki i ka mea pauka kala ke hoʻopili i ke kūpaʻa kemika o ka PTFE, insulation, tensile ikaika a me nā waiwai mechanical.No laila, pono e hoʻomaopopo i kekahi mau hanana kūikawā.Hoʻokō ka PTFE kala i nā koi o nā mea kūʻai aku i loaʻa nā koi no nā kala ʻike.
ʻO ke kūʻai ʻana i ka paipu PTFE kūpono ʻaʻole wale e pili ana i ke koho ʻana i nā kikoʻī like ʻole no nā noi like ʻole.ʻOi aku e koho i kahi mea hana hilinaʻi.BesteflonʻO Fluorine plastic Industry Co., Ltd. kūikawā i ka hana ʻana i nā mea kiʻekiʻeNā paipu PTFEa me na paipu no 20 makahiki.Inā loaʻa nā nīnau a me nā pono ptfe tube, e ʻoluʻolu e nīnau iā mākou no ka ʻōlelo aʻoaʻo ʻoihana.
