Kedu ka PTFE Igwe ọkụ dị elu si ejikwa ọkụ ọkụ?

N'ọtụtụ ngwa ụlọ ọrụ mmepụta ihe, ákwà PTFE na okpomọkụ na-adịgide adịgide. A naghị ekpughe Ọ na-enweta mgbanwe okpomọkụ ngwa ngwa - site na friza gaa na oven, site na ịpị ọkụ ruo n'ikuku ikuku, ma ọ bụ site na mkpuchi okpomọkụ gaa na mpaghara dị jụụ. Nke a ka a na-akpọ ujo ọkụ.

Azịza ya dabere na oke okpomọkụ. N'ime oke arụ ọrụ ya, akwa PTFE na-arụ ọrụ nke ọma. Ma gbanye ya nke ukwuu, mkpuchi ahụ ga-adakwa.

Aokai PTFE anwalela nguzogide ujo n'ofe ngwaahịa anyị. Ntuziaka a na-akọwa ihe dị iche iche okpomọkụ dị mma, ka ihe na-arụ ọrụ, na ihe ị ga-ezere.

Okpomọkụ dị iche iche enwere ike ịnabata - Gịnị dị mma?

1. Oke ọrụ nkịtị (-70°C ruo 260°C)

Ịgba ígwè okpomọkụ ngwa ngwa n'ime oke a agaghị emebi ákwà ahụ doro anya. Ihe ngosi ngwa a na-ahụkarị gụnyere ịgbanwee ugboro ugboro n'etiti nchekwa oyi na -50C yana ngwa ịpị ọkụ na 260C. Ihe na-agbasawanye na nkwekọrịta, mana mkpuchi PTFE na-anọgide na-emebi emebi na mkpụrụ osisi fiberglass anaghị agbawa.

Ngwa Ọmụmaatụ: Akụrụngwa na-ehicha friji ebe eriri na-agbanwe n'etiti friji miri emi (-40°C) na oven nkụ (150°C). PTFE akwa na-ejikwa nke a kwa ụbọchị.

2. Oke okpomọkụ dị iche (gburugburu 250°C delta)

Akwa PTFE adịchaghị nwere ike iguzogide oke ujo - dịka ọmụmaatụ, imikpu ya ozugbo na mmiri oyi 10ºC mgbe ekpughere ya na 260°C (ọdịda 250°C). Ihe mkpuchi ahụ agaghị agbawa ma ọ bụ kpochapụ mgbe okirikiri ugboro ugboro. akwadola nke a Aokai PTFE .

3. Mpaghara ihe egwu - n'elu 300 ° C

Ihe ize ndụ nke mmebi na-ebili nke ukwuu ma ọ bụrụ na ọdịiche okpomọkụ na-abawanye, dị ka ngwa ngwa jụrụ oyi site na okpomọkụ karịa 300 ° C. Ozugbo akwa ahụ gafere 300 ° C (n'akụkụ ebe mgbaze nke PTFE nke 327 Celsius C), mkpuchi ahụ na-aghọ ọkara a wụrụ awụ na-adịghị ike. Igwe oyi na mberede na-ebute oke mbelata na mgbawa.

Ụkpụrụ Ọrụ - Mkpụrụ vs. mkpuchi

A na-ekpebi arụmọrụ ujo thermal site na ihe mgbakwunye nke mkpụrụ osisi fiberglass na mkpuchi PTFE.

1. Fiberglass mkpụrụ - ọkpụkpụ kwụsiri ike

• Ebe nro dị elu karịa 800 ° C

• Ọnụ ọgụgụ dị oke ala nke mgbasawanye ọkụ (ihe dị ka 5 × 10⁻⁶/°C)

• Nke a na-ebute oke nrụgide na njikọ njikọ

Ihe mere o ji ka na-arụ ọrụ: Ihe mkpuchi PTFE dị gịrịgịrị (na-abụkarị 10-30 μm) na mgbanwe. Usoro impregnation na-ejikọta ya na fiberglass. N'ime oke okpomọkụ nkịtị, mkpuchi ahụ nwere ike ịgbatị ma gbakee na-enweghị mgbawa. N'ebe oke okpomọkụ ma ọ bụ n'ichepụta adịghị mma, nchekasị ahụ karịrị ike mkpuchi.

Aokai PTFE mara: akwa ọkwa ọkwa anyị na-eji ọtụtụ ngafe impregnation, na-ekwe ka PTFE banye miri emi n'ime akwa fiberglass. Nke a na-emepụta igwe 'arịlịka' nke na-eguzogide delamination n'oge ịgba ígwè ọkụ - isi ihe dị iche na mkpuchi dị ala nke na-anọdụ ala naanị n'elu.
