PTFE me Teflon: He ōrite rāua? – Besteflon

I a mātou e mahi tahi ana me ngā kiritaki o tāwāhi, he maha ngā wā ka tūtaki mātou ki tēnei āhuatanga: e tohu ana ngā tuhi i tētahi ngongo PTFE, ko te utu a te kaiwhakarato he ngongo Teflon, ā, ka waiho ngā tīma hoko kia kore e tino mōhio mēnā kei te kōrero rātou mō te rauemi kotahi, ā, ka roa te wā e whakaū ana. He raruraru nui ake, ka whakamahia e ētahi kaiwhakarato te "Teflon" hei tohu mō te PFA, te FEP rānei—nā te mea he maha ngā rauemi e kapi ana i te tohu hokohoko Teflon®. Ka whakaratohia e tēnei tuhinga he whakamārama whānui mō ngā kupu, ngā tohu hokohoko, me ngā whakaaro hoko mahi i te wāhi kotahi.

•He rite tonu te rauemi o te PTFE me te Teflon;Ko Teflon® te ingoa hokohoko noa iho mō te PTFE.

•Heoi, kua whānuitia te whakamahi i te kupu "Teflon" i roto i te umanga, ā,tērā pea e pā ana ki te PTFE, te PFA, te FEP rānei.

•Kei a Chemours (ko DuPont i mua) te tohu hokohoko Teflon®;kāore e whakaaetia kia whakamahia e ngā kaiwhakarato kore mana i runga i te ture.

•Me whakahua te PTFE i roto i te ota hoko, kaua ko te Teflon.hei karo i te koretake o te tuku.

•Ko te "ngongo Teflon" he tino iti te utu, kāore pea i hangaia mā te whakamahi i ngā rauemi mata o Chemours;me whakaū tēnei.

He rite tonu te matū o te PTFE me te Teflon?

Koinei te pātai matua, ā, he māmā noa iho te whakautu: āe, he rite tonu te rauemi o te PTFE me te Teflon. Heoi, kāore te tikanga o "te rauemi kotahi" me te kupu "kotahi" i roto i ngā horopaki hokohoko—mā te mārama ki tēnei rerekētanga ka māmā ake ngā pātai katoa e whai ake nei.

PTFE = Polytetrafluoroethylene = Ingoa matū

Ko te PTFE he whakarāpopototanga mō te Polytetrafluoroethylene, e mōhiotia whānuitia ana i te reo Hainamana ko te "polytetrafluoroethylene." He tohu matū tēnei e pā ana ki tētahi pūmua i hangaia mai i ngā monomer tetrafluoroethylene. Ahakoa te pūtake o ngā rauemi mata, ko ngā hua polytetrafluoroethylene katoa e hangaia ana e tētahi kamupene ka tapaina rite tonu ko te PTFE—he kupu ahumahi paerewa kāore i te nō tētahi kaihanga motuhake.

Teflon® = Tohu hokohoko rēhita o DuPont

He tohu hokohoko rēhita a Teflon® nā Chemours (i wehea mai i DuPont i te tau 2015). I te tau 1938, i kitea pōhēhētia e te kaipūtaiao o DuPont, a Roy Plunkett, te PTFE, ā, i te tau 1945 ka tīmata te kamupene ki te hokohoko i raro i te tohu hokohoko Teflon®. Ko te tikanga, ko Teflon® e pā ana ki "PTFE i hangaia e DuPont/Chemours" — pērā i a Kleenex® e tohu ana i tētahi waitohu tauera pepa motuhake.

Heoi, he uaua ake te ao tūturu i tā ngā whakamāramatanga e kīia ana. I roto i te umanga, kua noho te kupu "Teflon" hei kupu ōrite ki te PTFE, ā, he maha ngā kaiwhakarato e whakamahi ana i tēnei kupu hei whakaahua i ā rātou hua me te kore whakamanatanga—he mahi tino noa i roto i te rāngai hangahanga o Haina: ina tono ngā kaihoko "ngā ngongo Teflon," ka mōhio whānuitia e ngā kaiwhakarato he kupu tēnei e pā ana ki ngā ngongo PTFE. I Besteflon, he maha ngā wā ka tūtaki mātou ki ēnei momo pātai; i muri i te whakaū i ngā whakatakotoranga rauemi, ka tohua tonutia e mātou te PTFE i roto i ngā tuhinga mana hei karo i te koretake.

 

He aha te take kāore te kupu "Teflon" e tohu ana i te PTFE?

Me he ingoa hokohoko noa iho a Teflon mō te PTFE, kua māmā noa iho te take. Heoi, i roto i te ao tūturu, neke atu i te kotahi te fluoropolymer e hokohokohia ana e Chemours i raro i te ingoa waitohu Teflon®. Koinei te pūtake o te pōhēhētanga o ngā hoko, ā, e whakaatu ana i te hiahia kia nui ake te tika o ngā tuhinga whakatakotoranga.

Kei te hokona e Chemours ēnei rauemi i raro i te waitohu Teflon®:

 

 

Ko te tikanga tēnei, ina kī mai te kaiwhakarato "e tuku ana mātou i ngā ngongo Teflon," tera pea kei te kōrero rātou mō ngā ngongo PTFE, ngā ngongo PFA, ngā ngongo FEP rānei. He rerekē rawa te ātete o ēnei rauemi e toru ki te pāmahana teitei, ngā whakaritenga tukatuka, me te utu; mā te hapa kotahi o te pūāhua ka rerekē rawa te taumata mahi i te wā e tukuna ana.

Tohutohu: Whakamahia tonu ngā ingoa matū (PTFE/PFA/FEP) i roto i ngā ota hoko, ngā whakaritenga, me ngā kirimana; kaua e whakamahi i te "Teflon." Ehara tēnei i te kōrero whakakatakata noa iho engari ko te huarahi māmā rawa atu hei ārai i ngā tautohe tuku. Kia mahara ko ngā Besteflon katoaNgā hua ngongo PTFEkua tapaina ki ngā ingoa matū kaua ki te "Teflon" - nā te mea ko te tika te mea nui ake i te ngāwari.

 

Ko wai te rangatira o te tohu hokohoko Teflon®?

Ahakoa te āhua nei he take ture te mana pupuri tohu hokohoko, ka whakatau tika mai mēnā ka taea e ō kaiwhakarato te whakamahi ture i te kupu "Teflon" me ngā rauemi e whakamahia ana i roto i te "ngongo Teflon" e hokona ana e koe.

Hītori Tohu Waitohu

•1938,Nā te kaipūtaiao DuPont, a Roy Plunkett, i kite te PTFE.

•1945:I rēhitatia e DuPont te tohu hokohoko Teflon®, ā, ka tīmata tana hokohoko.

•2015:I wehea e DuPont tana pakihi matū mahi hei kamupene motuhake ko Chemours, ā, ko te tohu hokohoko Teflon® i tohaina ki a Chemours.

•Stawhiti rawa, kei a Chemours te tohu hokohoko Teflon®, ā, ka tukuna e ia ngā mana raihana ki ngā kaihoko kapia PTFE puta noa i te ao.

He aha te tikanga o tēnei mō te hokohoko?

E rua ngā pānga whaihua o te mana ture o tētahi tohu hokohoko mō te hoko:

1. Kāore pea tō kaiwhakarato i whakamanahia ki te tāpiri tapanga Teflon® ki te hua.Mena ka whakamahia e te kaihanga paipa te tohu Teflon® i runga i ngā tapanga hua, i ngā paetukutuku rānei, me te kore e whiwhi whakaaetanga waitohu mai i Chemours, he takahi ture tēnei i te tohu hokohoko. Kāore tēnei e pā ki te kounga o te rauemi tonu—he maha ngā wheketere o Haina e whakamahi ana i te kapia PTFE i hangaia i te motu (hei tauira, Dongyue, Haohua, me ētahi atu), e tutuki katoa ana i ngā paerewa mahi—engari kāore e taea e koe te tapa i te hua whakamutunga ki te Teflon®.

2. Kāore e taea te whakamahi i te "ngā ngongo Teflon" hei pūtake mō te whakaae.Me kī te "ngūpa Teflon" i roto i te ota hoko; ka taea e te kaiwhakarato te tuku i tētahi momo paipa fluoropolymer. Ko te kī anake i te "ngūpa PTFE" me te "ngūpa PFA" ka taea te whakamahi hei paerewa whakaae hangarau mēnā he tautohe.

 

He tino ōrite ngā āhuatanga o te PTFE mai i ngā pūtake rerekē?

I muri i te whakamārama i ngā take e pā ana ki ngā tohu hokohoko me ngā tikanga whakaingoa, ko te āwangawanga e whai ake nei mā ngā tīma hokohoko ko: He rite tonu ngā āhuatanga o ngā rauemi PTFE mai i ngā pūtake rerekē? Ko te whakautu he "tino rite, engari he iti noa ngā rerekētanga" — kāore ēnei rerekētanga e pā ki te mahi i te nuinga o ngā tono engari ka puta pea he wero i roto i ngā horopaki tino tika.

Ngā wāhanga ōrite o ngā rauemi PTFE katoa

Ko te hanganga matū o te PTFE he mekameka rārangi i hangaia e ngā hononga waro-hauora, ā, ka noho ōrite tonu ahakoa nō Chemours, Daikin, Dongyue, ētahi atu kaiwhakarato rānei te rauemi mata. He rite tonu ngā āhuatanga e whai ake nei puta noa i ngā momo PTFE katoa:

• Te koretake o te matū – kāore rawa he tauhohenga matū e puta.

• Awhe pāmahana mahi: -65°C ki te +260°C

• Tauwehenga waku – 0.1, he iti noa iho mō ngā rauemi totoka

• Ngā āhuatanga hiko-kore – Pūmau hiko-kore: 2.1; Kaha hiko-kore: 25 kV/mm

• Kore-piripiri – Kāore te nuinga o ngā matū e piri

He aha ngā rerekētanga ka puta pea

Kāore te ōritetanga o te hanganga matū e tohu ana i te ōritetanga katoa i waenga i ngā hua PTFE katoa. Tērā pea ka whai wāhi ēnei āhuatanga ki ngā rerekētanga i waenga i ngā hua mai i ngā puranga rerekē, i ngā kaiwhakarato rerekē rānei:

 

 

Ngā tūtohutanga matua mō ngā hoko:Mō ngā tono e pā ana ki te tukatuka matū tuku iho, ki te whakamahinga ahumahi whānui rānei, he iti noa iho ngā rerekētanga o ngā pūtake rauemi mata. Heoi, ki te mea he whakaritenga pakari te kaupapa mō ngā manawanui diameter ā-roto (hei tauira, ngā ngongo capillary PTFE), te maeneene o te pakitara o roto, te ātete pēhanga roa rānei, kaua e arotahi noa ki te mea he PTFE te rauemi, engari me te manatoko hoki i ngā kaha o te kaiwhakarato ki te whakaputa me te whakahaere kounga. Te tukanga whakahaere kounga mō BesteflonNgā ngongo maeneene PTFE——tae atu ki te whakamātautau pūmau hau, te whakamātautau pupuri pēhanga waipū, me te raupapa o ngā manatoko pēnei i te whakamātautau pēhanga teitei, te whakamātautau pahū waipēhi me te whakamātautau ngenge piko, kia mōhio ai kei te tutuki ngā hua i ngā paerewa o te umanga kirihou-pūoro. He mea hanga motuhake mō ēnei āhuatanga tino tika.

Me pēhea te tuhi i tēnei ki tētahi ota hoko?

I hipokina e te matapaki ngā rerekētanga o ngā tikanga whakaingoa, ngā tohu hokohoko, me ngā rauemi, ā, i te mutunga i arotahi ki tētahi pātai mahi: me pēhea te whakarārangi i ēnei taipitopito i roto i ngā ota hoko me ngā whakatakotoranga hangarau?

Whakamahia ngā ingoa matū, kaua ngā ingoa waitohu

 

Kāore e ranea te tuhi noa i te ingoa rauemi

Kāore e ranea te kī noa i te "ngā ngongo PTFE". Me whakauru ngā mea e whai ake nei ki roto i tētahi whakatakotoranga hoko katoa:

•Tau Rauemi:Paerewa Paerewa / Kai (e tutuki ana ki te FDA 21 CFR 177.1550) / Hauora

•Rahi: ID × OD × Matotoru o te pakitara, me ngā whakaritenga manawanui

•Te Roa me te Rahinga

•Whakamahinga Take:Āwhina i ngā kaiwhakarato ki te whakatau mēnā e hiahiatia ana he mana whakahaere kounga motuhake

•Ngā tiwhikete me ngā pūrongo whakamātautau e hiahiatia ana

I roto i te tukanga whakatau utu a Besteflon, ko te mahi tuatahi a ngā kaihangarau ko te manatoko i ēnei tawhā. Ehara tēnei i te whakahē—engari, ko te mārama ake o te tautuhi i ngā whakatakotoranga, ka maeneene ake te tukanga tuku, ā, ka iti ake ngā whakaritenga mahi anō.

 

Ngā Pātai Auau

Anei ngā pātai e tino pātaihia ana e ngā kiritaki mō "PTFE vs Teflon." Mena kāore tō āhuatanga i hipokina, tēnā pātai tika atu ki ā mātou kaihangarau mō te āwhina.

 

Q: E kī ana te kaiwhakarato kei te whakamahi ia i te "rauemi Teflon" – he pono rānei tēnā?

A: Me whakamārama anō. Mena kei te kōrero rātou mō te kapia PTFE waitohu Teflon® a Chemours, me tono koe kia puta he taunakitanga mō te puranga rauemi mata. Mena ka whakamahia noa te "Teflon" hei kupu whānui mō te PTFE (he mea noa i roto i te umanga), ka ahu mai pea te rauemi mata i tētahi kaiwhakarato kapia PTFE—ehara tēnei i te mea he raruraru, engari kāore e taea te kī nō Chemours. Mō te nuinga o ngā tono ahumahi, ko ngā kapia PTFE kounga teitei i hangaia i te motu (pērā i ērā mai i Dongyue, i Haohua rānei) e tutuki ana i ngā whakaritenga mahi katoa.

Q: Ka taea te tā i te kupu "Teflon" ki runga i te ngongo PTFE?

A: Mena kāore te rauemi paipa e whakamahi ana i te kapia Teflon® a Chemours, kāore rānei he whakaaetanga mai i a Chemours mō te tohu hokohoko, ko te tā "Teflon" ki runga i te hua he takahi i te tohu hokohoko. E taunakihia ana kia tā "PTFE" ki runga i te paipa – he tika, he mārama hoki tēnei huarahi.

Q: Kia pēhea te iti iho o ngā kapia PTFE a Chemours ki te whakataurite ki ngā hua PTFE i hangaia i te motu?

A: I roto i ngā tono ahumahi tuku iho, he iti noa ngā rerekētanga. Ko ngā rerekētanga nui ka puta ake i raro i ngā āhuatanga tino kino: te pumau o te ngongo capillary tino pai (ID<0.5mm), te ātete ngoki i te pāmahana teitei roa (>200℃), me ngā whakaritenga parakore motuhake mō ngā tono hauora, ngā tono haurua-ā-ira rānei. Mena kāore tō tono e uru ki ēnei āhuatanga tino kino, ka taea e ngā rauemi mata i hangaia i te kāinga te whakatutuki katoa i ngā whakaritenga i te utu iti iho.

Q: He "ngā ngongo Teflon" te tono a taku kiritaki – me pēhea taku mahi?

A: Whakaūtia ki te kiritaki mēnā e hiahiatia ana e rātou he ngongo PTFE, he ngongo PFA/FEP rānei. I te nuinga o te wā, ina kī ana ngā kiritaki ki ngā "ngā ngongo Teflon," ko te tikanga kei te kōrero rātou mō ngā ngongo PTFE. Kia whakaūtia, whakakapia te "ngā ngongo Teflon" ki te "ngā ngongo PTFE" i roto i te kirimana hei whakatakotoranga mana hei karo i ngā tautohe a muri ake nei.

Q: Me pēhea taku wehewehe wawe i waenga i te PTFE, te PFA, me te FEP?

A: Ko te tikanga māmā rawa: he mārama kore = PTFE, he mārama-haurua = PFA, he mārama katoa = FEP. E kitea mārama ana ngā wai i roto i te FEP mā roto i te ngongo; ko ngā mea i roto i te PFA e kitea ana engari he pōuriuri; ko ngā mea ia i roto i te PTFE kāore e kitea rawatia. He aromatawai tere noa iho tēnei—mō te kōwhiringa tino tika, tirohia te ripanga whakatairite 7-ahu i roto i te tuhinga.Ngongo PTFE vs PFA vs FEP.

Q: He aha i whakahuatia ai te kupu "Teflon" i runga i te Besteflon'spaetukutuku?

A: Kua whiwhi a Besteflon i te mana whaimana ki te whakamahi i te tohu hokohoko Teflon®, ā, kei te whakahaerehia i raro i ngā ture. He kaihanga motuhake mātou o ngā ngongo Teflon, tae atu ki ngā ngongo PTFE me ngā ngongo PFA/FEP.
