Cov kab xev hnyav feem ntau tuaj yeem tiv taus kev ua haujlwm kub txog li 250-300 degree F, tab sis thaum koj ncav cuag 400 degree F lossis siab dua, koj yuav tsum pib nrhiav cov ntaub ntawv tshwj xeeb uas haum rau cov ntawv thov kub.
7 Hom Tshav Kub Resistant Tapes
Yog tias koj tab tom nrhiav rau cov ntaub ntawv kub, koj thawj qhov kev xav yuav yog "Qhov twg ntawm cov kab hluav taws xob tiv thaiv hluav taws xob zoo tshaj rau kuv qhov project?"
Tom qab ua hauj lwm nrog ntau yam ntaub ntawv, peb txiav txim siab tias silicone nplaum, Kapton zaj duab xis, ntawv ci, iav ntaub, polyester daim kab xev, acrylic nplaum, thiab 3M VHB daim kab xev yog ib co ntawm cov feem ntau siv tshav kub-resistant adhesives, liners, thiab Adhesive cov ntaub ntawv. Lwm daim ntawv thov.
Cov npe hauv qab no yuav piav qhia txog ntau hom kab xev kom koj tuaj yeem xaiv qhov zoo tshaj plaws thaum koj xaiv cov khoom siv.
1. Silicone nplaum
Thaum koj tham txog cov ntaub nplaum uas tiv taus cua sov, xav tias yuav luag tshwj xeeb ntawm silicone.
Silicone adhesive bonds feem ntau tuaj yeem tiv taus qhov kub ntawm -60 degree F txog 500 degree F (-51 degree txog 260 degree), yam tsawg kawg rau kev siv sijhawm luv. Ntau daim kab xev tuaj yeem tiv taus luv luv ntawm tshav kub yam tsis siv lub sij hawm ntev, uas yog ib yam uas koj yuav tsum tau paub txog thaum nyeem cov ntaub ntawv sib txawv.
Silicone adhesives feem ntau yog siv nyob rau hauv high temperature aerospace, automotive, kev tsim kho thiab kev siv hluav taws xob.
2.KAPTON (polyimide) daim kab xev
Kapton daim kab xev, tseem hu ua polyimide daim kab xev, feem ntau yog siv nyob rau hauv aerospace daim ntaub ntawv vim nws tsis tshua muaj kub tsis kam thiab insulating zog.
Nws qhov ntsuas kub siab txhais tau tias Kapton tuaj yeem tiv taus qhov kub ntawm -103 degree F txog 500 degree F (-75 degree rau 260 degree), tab sis nws tau hais kom muaj sia nyob qhov kub thiab txias li -320 degree F rau 752 degree F (-196 degree rau 400 degree ).
3. Ntawv nyiaj
Cov ntawv nplaum (txhuas, tooj liab, stainless hlau, thiab lwm yam) yog siv rau EMI thiab RFI shielding, HVAC sealing thiab rwb thaiv tsev, thiab ntim.
Cov ntawv ci qhov kub ntawm qhov kev ua tau zoo yuav yog li ntawm -65 degree F mus rau 600 degree F (-54 degree rau 316 degree), tab sis qhov kub tsis kam yuav nyob ntawm seb hom ntawv ci koj siv.
4. Cov ntaub iav
Cov ntaub iav los yog fiberglass daim kab xev yog siv rau lub suab rwb thaiv tsev, cov khoom siv ntxiv, thiab lwm yam.
Zoo ib yam li Kapton thiab ntawv ci, iav ntaub yog qhov kub thiab txias heev thiab tuaj yeem tiv taus qhov kub thiab txias tshaj li ntawm 500 degree F (260 degree).
5. Polyester (PET) zaj duab xis daim kab xev
Polyester (PET) daim kab xev yog siv rau kev sib txuas hauv hluav taws xob, qhov kub thiab txias npog thiab splicing nyob rau hauv cov hmoov txheej daim ntaub ntawv.
Polyester daim kab xev feem ntau nyob rau hauv qhov kub ntawm -94 degree F mus rau 400 degree F (-70 degree mus rau 204 degree ) thiab txawm nyob rau ntawm kub siab dua thiab luv luv ci cycles.
6.3M VHB daim kab xev
3M's VHB ("High Bond") daim kab xev kuj tseem siv los hloov cov khoom siv txuas ntxiv kom txo tau daim ntawv thov hnyav lossis ua tiav daim ntawv cog lus ruaj ntseg, mus sij hawm ntev.
3M VHB daim kab xev tsis yog tshwj xeeb suav hais tias yog ib qho khoom "heat resistant". Txawm hais tias qee qhov VHB daim kab xev tuaj yeem tiv taus qhov kub txog li 450 ° F, feem ntau VHB daim kab xev poob qis dua qhov txwv. Ntau VHBs muaj qhov kub thiab txias li ntawm -40 degree F txog 200 degree F (-40 degree txog 93 degree ).
7. Acrylic nplaum
Acrylic tapes yog siv rau hauv daim ntawv thov kev sib raug zoo hauv tsheb, kev kho mob thiab ntau lwm yam lag luam. Lawv yog cov khoom siv muaj zog thiab hloov tau yooj yim siv los hloov cov khoom siv fasteners xws li screws lossis rivets.
Txawm hais tias acrylic tapes muaj qhov kub thiab txias txog li 400 degree F (204 degree), feem ntau cov tapes yeej zoo hauv qab qhov txwv. Raws li kev txwv qis, nws feem ntau lees txais tias qhov txwv yog -20 degree F rau -40 degree F (-28 degree rau -40 degree), nyob ntawm daim kab xev.
