Polytetrafluoroethene,whakarāpopototanga:PTFE
Ingoa Ingoa: PTFE, tetrafluoroethylene, kingi kirihou, F4.
Ngā Painga o te PTFE
PTFEKo ngā kirihou hangarau motuhake, i tēnei wā ko ngā rauemi ātete-waikura, e mōhiotia ana ko te "kingi kirihou". Ko ngā āhuatanga matua ko te ātete pāmahana teitei me te iti, te ātete waikura, te whakamarumaru teitei, te ātete koroheketanga, me te whakahinuhinu-ake.
E whakamahia ana i roto i te rererangi, ngā taputapu hiko me ngā taputapu hiko, te ahumahi matū, ngā mīhini me ngā taputapu, te kai me te hauora, ngā papu, ngā takirere me ngā paipa, ngā motuka me ngā kaipuke, ngā pūwero hau, me ētahi atu, ā, kua waiho hei rauemi tino nui mō te whakaoti rapanga i ngā hangarau matua o te ahumahi hou.
Ko ngā ngota PTFE ngota F korekore e tiaki ana, e tiaki ana hoki i te hononga CC, ā, he tino pumau te kaha hononga CF, he uaua ki te whakangaro i te mekameka ngota, he hanganga tino pumau. Ka whakamāramahia hoki e tēnei hanganga ngota ngā āhuatanga pai e whai ake nei o te PTFE.
Ātete ki te waikura:Haunga ngā konganuku kawakore rewa me ētahi whakarewa pēnei i ngā hauwaiwai kawakore katoa i runga ake i te 300 nekehanga Celsius, he ātete hoki ki te waikura roa e ētahi atu matū.
Ātete ki ngā pāmahana teitei me te iti: ka taea te whakamahi mō te wā roa i te -60+260℃.
Te whakahinuhinu teitei:te tauwehenga waku iti rawa i waenga i ngā rauemi totoka, kāore e taea te whakarite ki te hukapapa.
Kore-piri:ko te kukū mata iti rawa i roto i ngā rauemi totoka, kāore e piri ki tētahi matū.
Ātete ki te Huarere:Ko te ora roa rawa atu i waenga i ngā kirihou.
Kore-paitini:Ka taea te whakamahi i te rauemi hei oko toto horihori, kāore e paitini, kāore hoki e pāwera, me ētahi atu tauhohenga kino, hei rauemi kai me te rongoā.
Ngā āhuatanga ārai:He nui te kiriata matotoru pērā i te nūpepa hei ātete i te hiko ngaohiko teitei o te 1500V.
Hei tāpiri, kāore te PTFE e mimiti i te makuku, kāore e mura, ā, he tino ātete ki te hāora me te hihi ultraviolet.
Ngā huakore o te PTFE
Ahakoa he tino pai te mahi whānui a te PTFE, he iti te kaha miihini, he nui te tauwehenga whānui, he iti te ātete kakahu, he iti te ātete ngoki, he iti te kawe wera me ētahi atu ngoikoretanga. I roto i te kaha miihini me ētahi atu āhuatanga uaua, pēnei i te whakamahinga i roto i te umanga hiri takirere, ko tōna rohe tūturu o te whakamahinga haumaru ko te pāmahana i waenga i te -70 ~ +150℃. Hei whakakore i ēnei ngoikoretanga, ka taea te whakakī i te kapia PTFE ki ngā kaihoko whakapakari hei whakapai ake i ngā āhuatanga miihini o te rauemi, hei whakawhānui ake i te whānuitanga o te tono o ana rauemi.
He kupu whakataki ki ngā āhuatanga o te PTFE tae
Ko te tae taketake o te PTFE he mā miraka, ko te PTFE tae ia nā te mea kua whakakiia te rauemi turanga PTFE ki ngā rauemi āwhina. Ka taea te wehewehe i ngā rauemi āwhina ki ngā wāhanga e rua e ai ki te whakamahinga: te kaihoko whakarei me te kaihoko paura tae.
Te akomanga paura tae: kua whakakīia ki te paura tae i roto i te PTFE, ka taea te pango, te kōwhai, te whero, te kakariki, te kikorangi me ētahi atu. Ko te paura tae he mea hei whakarerekē noa i te tae o te PTFE, he iti noa te ōwehenga o te whakakī, nō reira ka taea te wareware i te pānga o te mahi taketake a te PTFE. I roto i te ariā, me taea e te paura tae te pā ki te pumau matū o te PTFE, te whakamarumaru, te kaha kume me ētahi atu āhuatanga miihini. Nō reira, me mōhio ki ētahi wā motuhake. Ka tutuki i te PTFE tae ngā hiahia o ngā kiritaki e hiahia ana ki ngā tae tirohanga.
Ehara i te mea ko te whiriwhiri i ngā whakaritenga rerekē mō ngā tono rerekē anake te mea e tika ana mō te hoko i ngā ngongo PTFE tika. He nui ake te whiriwhiri i tētahi kaihanga pono.BesteflonHe tohunga a Fluorine plastic Industry Co., Ltd. ki te hanga i ngā mea kounga teiteiNgā ngongo PTFEme ngā ngongo mō ngā tau 20. Mena he pātai me he hiahia mō ngā ngongo ptfe, tēnā koa whakapā mai ki a mātou mō ētahi atu tohutohu ngaio.
