Kedu ka Okpomọkụ si emetụta mkpuchi eletrik nke akwa akwa dị elu nke PTFE

A na-eji akwa akwa okpomọkụ dị elu PTFE eme ihe dị ka ihe mkpuchi ọkụ eletrik na ntinye waya, ihe ngbanwe mgbanwe, windings moto, na sekit ugboro ugboro. Mana okpomọkụ na-agbanwe - site na oyi na-atụ oyi ruo oke okpomọkụ - na-agbanwe àgwà mkpuchi ya. Ị nwere ike ịdabere na akwa PTFE na 200 ° C? Kedu ihe na-eme n'elu 260 ° C?

Azịza ya enweghị atụ. Ọdịdị molekụla nke PTFE na-enye ya mkpuchi pụtara ìhè n'ofe ọtụtụ n'ime oke ọrụ ya, mana ihe karịrị 260 Celsius na-ebute mbibi na-enweghị ike ịgbanwe. Ma ka oyi na-atụ na-eme ka ihe ndị na-emepụta eletrik dịkwuo mma, ha na-eme ka mkpuchi ahụ kewaa.

Aokai PTFE anwalela ihe mkpuchi n'ofe oke okpomọkụ. Isiokwu a na-agbaji arụmọrụ n'ime usoro atọ: arụ ọrụ nkịtị (-180 ° C ruo 260 ° C), oke elu (> 260 ° C), na obere okpomọkụ (<0 ° C), na isi data na resistivity, dielectric ike, na ihe bara uru.

Oke arụ ọrụ nkịtị: -180°C ruo 260°C – Mkpuchi kwụsiri ike

N'ime oke a, akwa akwa okpomọkụ nke PTFE na-edobe mkpuchi ọkụ eletrik pụtara ìhè ma kwụsie ike - uru bụ isi na-akwado ngwa ụlọ ọrụ ya zuru ebe niile.

1. Mpịakọta & Mgbochi Elu

Mechanism: Resistivity na-adaba nke ọma na oke okpomọkụ n'ihi na okpomọkụ dị elu na-eme ka mmegharị ọkụ nke ụdọ molekụla PTFE dịkwuo elu ma na-eme ka njem nke ndị na-ebu adịghị ọcha na-aga. Otú ọ dị, ọbụna na 200 Celsius C, PTFE na-eme ka ọtụtụ plastik injinịa dị na ụlọ okpomọkụ.

Rịba ama na nguzogide elu: Nguzogide elu na-enwekarị ike iru mmiri iru mmiri. PTFE fọrọ nke nta ka ọ bụrụ na-abụghị hygroscopic; mmiri dị n'elu na-ekupụ na okpomọkụ dị elu, na-ebuga mkpuchi elu kwụsiri ike karịa n'okpuru ọnọdụ ụlọ dị elu iru mmiri.

2. Ike Dielectric (Voltaji ndakpọ)

• Na-ebelata ka okpomọkụ na-ebili. Mmegharị ọkụ molekụla dị njọ na-eme ka ihe ahụ dịkwuo mfe na mmebi-ala eletrik.

• Site na okpomọkụ nke ụlọ ruo 200 Celsius, ike dielectric dị mkpụmkpụ na-ada site na 20%-40%.

• N'agbanyeghị nke ahụ, akwa akwa dị gburugburu 0.1 mm gbara ọkpụrụkpụ ka na-edobe ọtụtụ kilovolt (ma ọ bụ iri puku kilovolt maka akara ule) na 200 Celsius - ikike mkpuchi siri ike ka edobere.

3. Dielectric Constant & Dissipation Factor - Obere Mgbanwe

Ihe kpatara nke a ji dị mkpa: Nhazi molikula symmetric nke PTFE yana polarization ultra-low na-ekwe nkwa nnyefe mgbama kwụsiri ike yana ọgbọ okpomọkụ dị ala n'okpuru ọrụ ikuku dị elu & oke ọkụ. Nke a na-eme ka PTFE dị ka ezigbo ihe mkpuchi ikuku ugboro ugboro maka ngwa RF na ngwa ngwa ngwa ndakwa nri.

Aokai PTFE akwa okpomọkụ na-akọwapụta ndị ahịa maka mkpuchi mgbanwe mgbanwe dị elu n'ihi Dk ya kwụsiri ike (2.05 ± 0.05) na ultra-low tanδ (0.0002-0.0005) gafee -50 ° C ruo 200 ° C. Anyị na-enye akụkọ nyocha ihe onwunwe dielectric mgbe a rịọrọ ya.

Oke Okpomọkụ Dị Elu: N'elu 260°C - Mmebi a na-apụghị ịgbanwe agbanwe

Ịgafe ogologo oge okpomọkụ ọrụ anabatara nke PTFE na-ebute mmebi anụ ahụ na kemịkal na-enweghị ike ịgbagha - ọ bụghị mgbanwe ihe onwunwe na-agbanwe agbanwe.

Ịdọ aka ná ntị dị egwu: Ọ bụ ezie na akwa fiberglass isi na-eguzogide 550-750 ° C tupu ọ dị nro, fiberglass na-enweghị mkpuchi na-amịkọrọ mmiri ngwa ngwa mgbe mkpuchi mkpuchi PTFE na-enweghị ike ijere onwe ya ozi maka mkpuchi voltaji dị elu.

Oke Okpomọkụ dị ala: N'okpuru 0 Celsius - Igwe ọkụ eletrik emelitere mana igwe na-emebi emebi

Isi ihe na-ewe: N'agbanyeghị nkwalite ọkụ eletrik na-ekpo ọkụ na obere okpomọkụ, mkpuchi PTFE na-aghọ ihe na-akụda. Maka ngwa cryogenic (dịka ọmụmaatụ, ahịrị nitrogen mmiri mmiri, magnets superconducting), hụ na etinyeghị akwa ahụ na mgbada dị nkọ ma ọ bụ nrụgide ọrụ n'okpuru -79°C. Ozugbo agbawara, iguzosi ike n'ezi ihe mkpuchi na-efunahụ n'agbanyeghị akụrụngwa eletrik.

Nchịkọta - Nọrọ n'ime 260 Celsius maka mkpuchi ntụkwasị obi

Na nchịkọta , n'ime okpomọkụ a na-atụ aro na-aga n'ihu na-arụ ọrụ (≤260°C), okpomọkụ na-ebute mmetụta ọjọọ na-adịghị mma na mkpuchi ọkụ eletrik PTFE dị elu. Volume resistivity na-anọgide n'elu 10⊃1;⊃3; Ω · cm na 200 Celsius; dielectric na-adịgide adịgide na 2.0-2.1; ihe nkwụsịtụ n'okpuru 0.001. Nke a na-eme PTFE otu n'ime ihe ndị na-ekpo ọkụ na-ekpo ọkụ na-ekpo ọkụ dị - karịsịa bara uru maka ngwa ngwa dị elu ebe ndị polymers ndị ọzọ na-ata ahụhụ dị ukwuu.

Ozugbo okpomoku karịrị 260 Celsius C, ọdịda mkpuchi na-amalite site na nro na nrụrụ igwe, na-emecha ghọọ ndakpọ eletrik zuru oke. N'elu 400 Celsius C, carbonization na-emepụta ụzọ na-adịgide adịgide. N'okpuru 0 Celsius C, akụrụngwa eletrik na-akawanye mma, mana nhịhịa arụ ọrụ nwere ike ịgbawa mkpuchi ahụ.

Achọrọ akwa PTFE dị elu nke nwere ihe mkpuchi mkpuchi maka oke okpomọkụ gị? Aokai PTFE na-enye data ule dielectric zuru oke site na -70°C ruo 260°C. Kpọtụrụ anyị maka ọnọdụ okpomọkụ, voltaji na ihe ị chọrọ ugboro ugboro.
