Dab tsi yog qhov cuam tshuam ntawm kev tswj lub vev xaib thaum lub sij hawm txheej txheej ntawm Teflon high-temperature daim kab xev ntawm lub flatness ntawm PTFE substrate thiab cov uniformity ntawm cov nplaum txheej?

I. Cov teebmeem ntawm Flatness ntawm PTFE Substrate

1. Yas Stretching thiab 'Necking' nyhuv

PTFE cov khoom muaj qhov tsis tshua muaj elastic modulus. Thaum lub nro tshaj nws elastic txwv, irreversible yas stretching tshwm sim, ua rau longitudinal elongation thiab transverse nqaim. Tom qab qhov nro tawm, lub substrate tsis tuaj yeem rov qab los rau nws cov qauv qub, ua rau slackness, longitudinal wrinkles, thiab tsis sib xws thickness. Hauv cov xwm txheej hnyav, cov qauv hloov pauv hloov pauv tuaj yeem tsim.

2. Creep (Cold Flow) Ncua Sijhawm

PTFE undergoes qeeb yas ntws nyob rau hauv sustained nro. Thaum lub sij hawm txheej txheej txheej, lub substrate softens thaum rhuab hauv qhov cub kom qhuav, thiab creep intensifies. Qhov tsis sib xws elongation no dhau los ua ' khov' tom qab txias, ua rau qhov tsis sib xws los yog qhov ntev ntev, uas tsis tuaj yeem tshem tawm los ntawm cov txheej txheem tom ntej.

3. Tsis sib xws Transverse Tension

Kev ua tsis zoo ntawm cov kev taw qhia chais lossis cov kev taw qhia ntug tsis raug tuaj yeem ua rau muaj qhov sib txawv ntawm qhov sib txawv ntawm cov npoo thiab qhov chaw, ua rau 'curled edges,' central blistering, los yog ib sab warping. Lub sijhawm nro hloov pauv tuaj yeem tsim cov kev hloov pauv hloov 'tight-loose marks' ntawm lub substrate nto, ncaj qha cuam tshuam flatness.

II. Cov teebmeem ntawm Txheej Txheej Txheej Txheej Adhesive

1. Kev hloov pauv hloov pauv ntawm txheej txheej

Nyob rau hauv riam-over-yob txheej, nro ncaj qha txiav txim siab txog qib ntawm kev sib cuag ntawm lub substrate thiab tus kws kho hniav hniav. Thaum nro dheev nce, lub substrate yog nias nruj, txo cov txheej hnyav; Thaum nro txo, lub substrate loosens, ua rau lub txheej hnyav. Cov kev hloov pauv no tsim cov kev hloov pauv raws sijhawm nyob rau hauv cov nplaum txheej tuab raws lub vev xaib, hu ua 'crosswise streaks' lossis 'zebra marks.'

2. Substrate Stretching cuam tshuam Adhesive Spreading

Kev nruj nruj heev thins PTFE zaj duab xis thiab tsim micro-wrinkles, uas yog tom qab ntawd rov ua dua los ntawm cov nplaum txheej rau ntawm qhov tsis sib xws ntawm substrate. Tom qab nro tawm thiab zaj duab xis shrinks rov qab, cov nplaum txheej yuav tsim micro-cracks vim tsis muaj kev ntxhov siab. Rau fiberglass npuag substrates, nruj nro ntau dhau ntawm cov xov paj interstices, ua rau cov nplaum nplaum ntau dhau, tuav tsis txaus, thiab txheej txheej ntxhib.

3. Coupled cuam tshuam thaum cua sov thiab ziab

PTFE muaj lub siab coefficient ntawm thermal expansion. Nyob rau hauv lub qhov cub kom qhuav, yog hais tias ntau qhov chaw nro tsis sib haum, lub tshav kub-softened substrate undergoes thib ob stretching, distorting lub ntub nplaum txheej nrog rau nws, ua rau ib tug nyias thiab tsis sib xws txheej tom qab ziab. Kev nruj nruj nyob rau hauv qhov chaw txias kuj tuaj yeem ua rau shrinkage wrinkles nyob rau hauv ib nrab qhuav nplaum txheej.

III. Cov Tswv Yim Tswj Cov Ntsiab Cai

1. Tshem tawm thiab txheej txheej

Tsis tshua muaj siab thiab nro tsis tu ncua yuav tsum tau thov, tsuas yog txaus los tiv thaiv lub substrate los ntawm wrinkling, tso cai rau nws nkag mus rau lub txheej txheej nyob rau hauv ib tug natural lub xeev thiab tsis txhob pre-stretching.

2. Kev ziab thiab cua txias

Precise fine-tuning ntawm floating rollers yuav tsum tau siv kom nquag plias rau thermal expansion thiab contraction ntawm lub substrate, thiab siab nro nyob rau hauv high-temperature aav yuav tsum nruj me ntsis zam.

3. Rov qab seem

Taper nro yuav tsum tau txais kev pom zoo, maj mam txo cov nip siab raws li qhov yob txoj kab uas hla nce, los tiv thaiv kev puas tsuaj ntawm coated nto los yog 'hloov' unevenness los ntawm lub hauv paus txheej rau cov nyob ib sab.

IV. Cov ntsiab lus

Cov segmented nro tswj yog qhov tseem ceeb hauv kev sib npaug ntawm cov yam ntxwv ntawm PTFE substrates - xws li tsis tshua muaj kev sib txhuam thiab yooj yim rau nkag mus - nrog rau qhov yuav tsum tau ua rau cov nplaum txheej sib xws. Nws ncaj qha txiav txim siab qhov ua tau zoo tshaj plaws ntawm Teflon daim kab xev hauv cov ntawv thov xws li qhov kub thiab txias tsis kam thiab cov khoom tso tawm.
