PTFE teepu Adhesion vs Okpomọkụ: Otu esi emeziwanye

Jiangsu Aokai New Materials, onye ọkachamara na-emepụta teepu okpomọkụ dị elu nke PTFE, na-ekerịta nghọta ọkachamara maka gị.

PTFE (Teflon) elu-okpomọkụ teepu ike n'ozuzu ga-eji na-aga n'ihu na okpomọkụ nso nke -196 ℃ ka 260 ℃ . N'ọtụtụ ngwa, oke nguzogide okpomọkụ nke teepu na-amachibidoro oyi akwa nrapado  karịa mkpụrụ PTFE. Ọrụ ya na-agbaso iwu doro anya metụtara ọnọdụ okpomọkụ:

Arụmọrụ nrapado na-agbada ka okpomọkụ na-ebili Site  na mmụba okpomọkụ, nrapado na-eji nwayọọ nwayọọ na-adị nro, na-akpụ akpụ na ọbụna na-eweda ala, na-eduga n'ibelata ike njikọta. Macroscopically, nke a na-egosipụta dị ka mwepu na njide adhesion.

Ọnụ ụzọ arụmọrụ ekpebiela site na ụdị  nrapado dị iche iche nwere oke ọdịda ọdịda dị iche iche:

 

Iji meziwanye oge njide okpomọkụ dị elu , a na-emekarị njikarịcha site na akụkụ atọ: nhazi nrapado, arụmọrụ mkpụrụ, na nhazi ihu igwe.

1. Adhesive Layer: kwalite Njikọ Na-adịghị Ike

·  Họrọ usoro nrapado na-eguzogide okpomọkụ dị elu : bute ụzọ nrapado nrụgide silicone maka ọnọdụ ọrụ okpomọkụ dị ogologo oge.

:  Mgbanwe Fluorocarbon Gbanwee nrapado silicone na ogige fluorocarbon iji bulie ogo mgbanwe iko (Tg) ruo 230 ℃. Mgbe awa 48 nke iji na-aga n'ihu na 260 ℃, ọnụego njigide adhesion ka gafere 85%.

·  Webata netwọk mmekọrịta : wulite nano-scale crosslinking networks iji welie ike na-ejikọta ọnụ na nkwụsi ike nke oyi akwa na okpomọkụ dị elu.

Tinye  ihe nkwụnye ọkụ : Tinye phenol na-egbochi na ihe ndị ọzọ na-ekpo ọkụ n'ime usoro iji gbochie mmebi oxidative nke ọma n'okpuru nnukwu okpomọkụ.

2. Substrate Layer: welie oke nguzogide okpomọkụ

·  Nano-filler mgbanwe : Tinye nano silica, boron nitride nanotubes na ndị ọzọ nanoparticles n'ime PTFE mkpụrụ na-etolite anụ ahụ crosslinking ihe. The okpomọkụ distortion okpomọkụ nwere ike mụbaa site 20-30 ℃, mgbe ịnọgide na-enwe ihe karịrị 90% nke mbụ adhesion na 260 ℃.

:  Ọgwụgwọ crosslinking molecular Crosslink PTFE molecular chains iji bulie okpomọkụ ọrụ na-aga n'ihu ruo 300 ℃.

:  Ihe mgbakwunye fiber Tinye eriri iko 25% ma ọ bụ eriri carbon iji bulie nguzogide na-akpụ akpụ site na 300%, na-eme ka ojiji na-aga n'ihu ruo 280 ℃.

3. Interface & Structural Design: kwalite nkwụsi ike njikọ

·  Ọgwụgwọ n'elu ala : Tinye ọgwụgwọ plasma ma ọ bụ kemịkalụ kemịkalụ n'elu PTFE iji mee ka ihe siri ike na arụ ọrụ elu, mee ka adhesion interfacial sie ike ma zere delamination na oke okpomọkụ.

Tinye  akwa mgbochi etiti : Fanye polyimide (PI) oyi akwa dịpụrụ adịpụ n'etiti mkpụrụ PTFE na nrapado iji gbochie ntinye nrapado na ịkwaga n'okpuru okpomọkụ dị elu, na-eme ka nkwụsi ike n'ozuzu ya dị elu.

Nwelite  nhazi ihe mejupụtara : Nabata usoro ihe mejupụtara multi-layer: mkpuchi PTFE + na-eme ka mkpụrụ dị elu + oyi akwa kwụsiri ike , iji dozie nguzogide okpomọkụ na nrapado arụmọrụ zuru oke.

Nchekwa  mgbasawanye okpomọkụ : ọnụọgụ mgbasawanye linear nke PTFE dị ihe dị ka okpukpu iri karịa nke ígwè.

Debe oghere nke 0.15-0.3 mm  n'ime nhazi nhazi iji hapụ nrụgide okpomọkụ nke ọma.
