Kub & Viscosity Attenuation ntawm PTFE High-Temperature Daim kab xev

Jiangsu Aokai Cov Khoom Tshiab, cov chaw tsim khoom ntawm PTFE high-temperature daim kab xev, piav qhia txog kev hloov pauv ntawm PTFE daim kab xev tom qab siv qhov cub ntau dua.Lub attenuation ntawm kub tsis kam thiab tuav viscosity feem ntau yog nyob rau hauv cov nplaum txheej , es tsis yog PTFE substrate. Cov qauv molecular ntawm PTFE substrate yog qhov ruaj khov thiab tsis tshua muaj hnub nyoog qis dua 260 ° C. Nyob rau hauv sib piv, high-temperature nplaum txheej xws li silicone undergo thermo-oxidative laus nyob rau hauv rov qab cua sov, uas thaum kawg txiav txim siab lub neej kev pab cuam ntawm PTFE high-temperature daim kab xev.

1. Kev cai lij choj ntawm qhov kub thiab txias

Qhov kub ntawm qhov cub li qub (≤ 260 ° C) Cov nplaum nplaum muaj hnub nyoog maj mam thiab nce zuj zus, nrog rau qhov nominal kub tsis kam txo xyoo los ntawm xyoo. Nws lub neej ua haujlwm ntev yog li 1-3 xyoos.

Qhov kub thiab txias me ntsis (260-300 ° C) Adhesive aging accelerates sharply, thiab lub neej kev pab cuam poob qis heev los ntawm ob peb xyoos mus rau ob peb lub lis piam xwb.

Qhov kub thiab txias (＞ 300 ° C) Cov nplaum nplaum softens, decomposes thiab txawm carbonizes sai, ua rau tam sim ntawd viscosity poob thiab tev tawm hauv lub sijhawm luv luv.

Rov ua dua thermal cycling Ntau zaus cua sov thiab cua txias ua rau muaj kev cuam tshuam thermal, ua rau micro-delamination ntawm cov nplaum thiab substrate, thiab ua kom tsis txhob kub tsis kam.

2. Kev cai lij choj ntawm kev tuav viscosity

Kev poob qis hauv ib txwm ua haujlwm Tsis pub dhau qhov ntsuas kub ntawm qhov ntsuas, qhov tuav viscosity maj mam txo qis nrog kev nce qhov cub, thiab cov nplaum txheej ua tawv tawv thiab embritted dhau sijhawm.

Nthuav attenuation nyob rau hauv kub-kub thiab hnyav hnyav Thaum overheated los yog raug rau cov tshuaj lom neeg cov xov xwm, lub sib raug zoo lub zog yuav poob los ntawm ntau tshaj 50% tom qab txias.

Lub ntsiab lus tseem ceeb ntawm kev ua haujlwm tsis ua haujlwm Txawm tias daim kab xev tseem zoo li qub, nws cov khoom tsis yog lo thiab tuav yuav ua tsis tau ua ntej, yuav tsum tau hloov sijhawm.

3. Tej yam tseem ceeb ua rau kev ua haujlwm tsis zoo

Adhesive hom Silicone siab-rhiab nplaum nplaum nta qhov kub tsis kam mus txog 260 ° C, deb tshaj li acrylic nplaum (tsuas yog 120-150 ° C).

Substrate qauv Fiberglass-reinforced PTFE daim kab xev muab zoo heev seem stability thiab thermal creep kuj, nrog ib tug ntev kev pab cuam lub neej tshaj li ntshiab PTFE zaj duab xis daim kab xev.

Kev ua haujlwm ib puag ncig Kev sib txhuam thaum lub sijhawm ua haujlwm ntawm qhov cub, nrog rau kev sib cuag nrog cov kuab tshuaj lossis cov dej ntws, yuav ua rau lub cev thiab tshuaj lom neeg degradation.

Cov khoom tsis zoo Cov kab xev tsis zoo feem ntau muaj qhov ntsuas qhov ntsuas kub tsis zoo, muaj hnub nyoog sai thiab ua tsis tiav tom qab tsuas yog ob peb lub voj voog.

4. Cov lus pom zoo siv kom qeeb qeeb degradation

Kev tswj qhov kub thiab txias Ua kom ntev mus ntev ua haujlwm kub hauv qab 260 ° C thiab tsis txhob ua haujlwm kub dhau.

Tsim nyog qauv xaiv Xaiv cov khoom zoo silicone-raws li PTFE daim kab xev, uas tuaj yeem tiv taus ntau tshaj 500 lub voj voog hauv SMT thiab cov txheej txheem zoo sib xws.

Daim ntawv thov txheej txheem Ua tib zoo ntxuav qhov chaw sib txuas nrog cov ethanol ua ntej lamination kom ntseeg tau tias muaj kev ntxhov siab thiab nruj nruj.

Txheej txheem optimization Txo qhov tsis tsim nyog thermal shock zaus kom txo qis thermal kev puas tsuaj rau cov nplaum txheej.

Kev cia kom zoo Khaws cov ntaub nplaum uas tsis siv rau hauv qhov chaw kaw, tsaus, txias thiab qhuav kom tsis txhob muaj cov nplaum nplaum ua ntej.

Kev hloov pauv tam sim ntawd yuav tsum tau hloov tam sim ntawd thaum txheej txheej txheej, carbonization saum npoo, ntug warping lossis poob ntawm kev ua haujlwm tsis zoo, thiaj li ua kom ruaj khov.
