Yuav ua li cas txhawm rau txhim kho qhov rov ua dua qhov ua tau zoo ntawm PTFE High-Temperature Adhesive Tapes

PTFE high-temperature daim kab xev yog feem ntau siv nyob rau hauv daim ntaub ntawv uas nws yuav tsum tau muab tshem tawm thiab rov qab siv ntau zaus - nyob rau hauv lub tshav kub sealers thaum lub sij hawm hloov, ntawm 3D tshuab luam ntawv txaj, los yog raws li ib ntus npog nyob rau hauv electronics los ua ke. Txawm li cas los xij, tom qab ob peb lub voj voog, ntau daim kab xev poob tack, tawm qhov seem, lossis tsis ua haujlwm.

Cov xov xwm zoo: rov siv tau tuaj yeem txhim kho tau zoo dua los ntawm kev sib koom ua ke kev hloov kho thoob plaws plaub qhov loj: nplaum formulation , substrate kho , backside txheej tsim , thiab kev ua haujlwm zoo & kev saib xyuas.

Aokai PTFE tau tsim PTFE daim kab xev rov siv tau siv cov qauv no. Phau ntawv qhia no piav qhia txhua qhov loj me.

Adhesive Formulation Optimization - Qhov Tseem Ceeb

Cov nplaum nws tus kheej yog qhov kev txiav txim siab ntawm kev rov siv dua. Plaub lub tswv yim tsim cov tswv yim txhim kho kev rov ua dua adhesion.

1. Txhim kho cohesive zog thiab crosslink ceev

Txais high-polymerization-degree silicone cov pos hniav thiab nce crosslinking qhov chaw kom tig cov nplaum nplaum rau hauv cov khoom elastic. Qhov no tiv thaiv tearing lossis adhesive hloov mus rau lub sijhawm rov tev thiab txo tus kheej poob ntawm cov kua nplaum. Ib tug zoo-crosslinked nplaum peels huv si dua li splitting sab hauv.

2. Tsawg silicone migration mis

Siv lub platinum-catalyzed ntxiv kho qhov system thiab tshem tawm cov khoom uas tsis muaj molecular-yuag. Qhov no inhibits lub exudation ntawm me me-molecule silicone roj uas paug cov nplaum nplaum thiab tsis txhob nruam viscosity attenuation. Low-migration adhesives tuav lawv qhov qub tack dhau ntau lub voj voog.

3. Microphase qauv rau repositionable adhesion

Ntxiv MQ silicone resin los yog tsim ib qho kev sib cuam tshuam polymer network los tsim cov ntu nyuaj-mos ntu microphase sib cais :

• Cov ntu nyuaj - muab kev sib koom ua ke los tiv thaiv cov kua nplaum residual hloov mus

• Mos ntu - muab tackiness

Ib feem ntawm cov viscosity tuaj yeem rov qab tau tom qab so cov plua plav tawm ntawm qhov chaw. Qhov 'repositionable' tus cwj pwm no yog qhov zoo tagnrho rau cov ntawv thov uas xav tau ntau yam kev hloov kho thaum sib dhos.

4. Dej-ntxuav rov qab kho cov nplaum nplaum

Tom qab cov nplaum nplaum tau stained nrog plua plav, qhov hloov kho silicone nplaum tuaj yeem muab yaug nrog dej huv lossis hnyav hnyav, rov ua dua 90% ntawm nws qhov qub tack tom qab ziab. Qhov no yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig rau kev siv chav huv lossis khoom siv hluav taws xob uas tsis muaj kev sib kis.

Ntxiv dag zog rau Anchoring Force ntawm PTFE Substrate thiab Adhesive Txheej

PTFE nta ultra-low nto zog (18-20 dynes / cm), uas yooj yim ua rau tag nrho cov nplaum hloov pauv - tag nrho cov nplaum txheej nqa tawm lub nraub qaum - tsis muaj kev kho mob siab.

1. Substrate nto ua kom

Ua cov tshuaj etching nrog sodium-naphthalene complex los yog plasma kev kho mob ntawm PTFE fiberglass ntaub los qhia polar pawg xws li C = O thiab -OH, enabling tshuaj bonding los yog muaj zog mechanical interlocking ntawm nplaum thiab substrate. Qhov no tiv thaiv cov nplaum los ntawm tev tawm lub nraub qaum thaum tshem tawm.

2. Tshwj xeeb primer txheej

Siv cov tshuaj pleev xim rau ua ntej cov nplaum nplaum los tsim cov tshuaj txhuam hniav ntawm PTFE thiab silicone nplaum, tshem tawm cov kev ua tsis tiav tag nrho. Cov primer ua raws li qhov sib txuas molecular, sib txuas rau ob qho tib si PTFE nto thiab silicone PSA.

Aokai PTFE siv cov txheej txheem primer uas ua kom xoom xoom xaim mus rau kev thim rov qab txawm tias tom qab 10+ kev tshem tawm mus.

Backside (Tso Nto) Kev kho kom zoo

Lub PTFE backside ib txwm xa tawm kev ua tau zoo, tsis tau rov ua dua thiab rov ua dua tseem ua rau cov nplaum nplaum los ntawm kev sib txhuam thiab micro-tearing.

1. Txhim kho qhov kev tso tawm rov qab txheej

Thov ib qho ntxiv high-crosslink-density fluorosilicone lossis silicone tso txheej rau ntawm PTFE rov qab. Nws tuav ruaj khov unwinding quab yuam nyob rau hauv qhov kub thiab txias thiab ntev compression, tiv thaiv nto fiber ntau rub thiab kev puas tsuaj rau cov nplaum txheej ua ntej rov siv dua.

2. Embossed lossis micro-structured backside

Txo qhov chaw sib cuag tiag tiag ntawm cov txheej txheem rov qab thiab cov nplaum nplaum, txo qis kev puas tsuaj ntawm cov kua nplaum thaum lub sij hawm tev. Qhov no micro-textured nto minimizes 'stick-slip' cov nyhuv uas tuaj yeem rhuav cov nplaum.

Cov Txheej Txheem Kev Ua Haujlwm thiab Kev Txhim Kho

Txawm tias qhov zoo tshaj plaws-engineered daim kab xev yuav ua tsis tau ntxov yog tias ua haujlwm tsis zoo. Cov kev coj ua zoo txuas ntxiv rov siv tau ntau heev.

1. nquag ntxuav ntawm cov nplaum nplaum

viscosity poob feem ntau yog tshwm sim los ntawm cov plua plav paug saum npoo. So lub ntsej muag maj mam nyob rau hauv ib qho kev taw qhia nrog ib daim ntaub tsis muaj plua plav dipped hauv dej huv los yog dej cawv tsis muaj dej, ces huab cua qhuav los yog cua txias - tackiness yuav zoo heev. Kev tu tsis tu ncua ntawm kev siv yog ib qho kev saib xyuas zoo tshaj plaws.

2. Zam kev puas tsuaj nyob rau hauv kev ua haujlwm hnyav

• Tshem tawm maj mam ntawm lub kaum sab xis me me (ze li 180 °) kom txo qis kev pheej hmoo ntawm kev sib koom ua ke.

• Tsis txhob siv qhov ntsuas kub siab tshaj - cov nplaum yuav muaj hnub nyoog thiab tawv, poob rov siv dua.

• Ntxuav lub adherend nto ua ntej - cov roj stains sai kis cov nplaum txheej thiab tsis tuaj yeem tshem tawm tag nrho.

3. Tshem tawm cov npuas npuas thaum lub sij hawm lamination

Plua plav zoo li sib sau nyob ib ncig ntawm cov npoo npoo thiab ua rau muaj kev ntxhov siab hauv zos, ua kom cov nplaum nplaum nrawm nrawm. Daim ntawv thov tsis muaj npuas zoo (siv lub squeegee lossis cov menyuam) txuas rau daim kab xev lub neej rov siv tau.
