High Temperature tapes yog hais txog cov nplaum nplaum uas siv rau qhov chaw ua haujlwm kub.Nrog lub ntsiab feature ntawm tev tawm yam tsis muaj residue, high kub tapes yog tsuas yog siv los ua daim npog qhov ncauj thiab tiv thaiv muaj nuj nqi thaum lub sij hawm hmoov txheej, Plating, Circuit Court board luam ntawv, yoj soldering masking thiab SMT mounting.Nws tuaj yeem siv rau ntau hom kev lag luam, xws li Electronic kev lag luam, Automotive kev lag luam, Aerospace kev lag luam, thiab lwm yam.
Ntawm no peb xav faib cov high temp tapes raws li hauv qab no:
Ua ntej, qhov kub thiab txias tuaj yeem muab faib raws li cov neeg nqa khoom sib txawv.
Polyimide daim kab xev,Kuj tseem muaj npe hu ua Kapton lossis Golden Finger, uas yog cov khoom siv hluav taws xob zoo tshaj plaws hauv kev ua lag luam nrog luv luv siv qhov kub thiab txias tsis kam mus rau 350 ℃.Lub thickness ntawm Kapton zaj duab xis yog 12.5um, 25um, 35um, 50um, 75um, 100um thiab 125um, thiab peb lub Hoobkas kuj tuaj yeem kho lwm cov thickness tshwj xeeb xws li 150um, 200um lossis 225um raws li tus neeg thov.Amber thiab Dub xim yog ob qho xim ntau tshaj plaws, thiab xim dub kuj tseem tuaj yeem ua glossy lossis matte tiav.Lwm cov xim zoo li Ntsuab, Liab lossis Pob tshab tuaj yeem hloov kho nrog qee yam MOQ thiab tus nqi siab dua.
Polyester kuj hu ua PET (Lub npe tshuaj yog polyethylene terephthalate, tseem hu uaMYLAR daim kab xev).Nws melting kub yog 240 ℃, thiab lub siab tshaj plaws ua hauj lwm kub yog 230 ℃, thaum lub kub ua hauj lwm zoo tshaj plaws nyob rau hauv 180 ℃.PET Zaj duab xis nta nrog kev xa tawm siab thiab tus nqi pheej yig, uas tsis yog siv los uakub kub kuj daim kab xevtab sis kuj yogMylar rwb thaiv tsev daim kab xevlos yogPET tiv thaiv zaj duab xis.Feem ntau ntawm cov yeeb yaj kiab PET yog cov xim pob tshab, dua li lwm cov xim xws li Amber xim, Liab, Xiav thiab ntsuab xim.
- 3. Cov Khaub Ncaws Khaub Ncaws
Cov ntaub iav yog ua los ntawm iav fiber ntau thiab woven li ntaub, thiab dav dav yog 130um xim dawb.Cov ntaub iav muaj zog tensile zog heev thiab tsim kua muag kuj siv tau raws li qhwv los yog kho rau transformer, Lub cev muaj zog, lithium roj teeb los yog txawm kuv cov khoom tu.
Cov iav fiber ntau yog ua los ntawm Teflon kho thiab coated nrog silicone nplaum tom qab kev kho nanochemical.Nws muaj anti-stick, kub kub thiab tshuaj tiv thaiv nta, uas muab ntau ruaj cov tshuaj ntawm ntim thiab kub sealing tshuab.Qhov dav dav ntawm Teflon iav ntaub yog 80um thiab 130um, lwm yam tshwj xeeb tuab xws li 50um, 150um lossis 250um tuaj yeem hloov kho raws li cov neeg thov.
PTFE Zaj duab xis muaj xws li tshem tawm PTFE cob los ntawm molding, sintering, txias rau hauv qhov khoob.Nws muaj cov khoom zoo heev dielectric, kev laus-tiv taus thiab corrosion kuj nta uas yog feem ntau siv rau xov sealing, yeeb nkab doping, kav dej thiab wrapping.Muaj peb xim rau kev xaiv, uas yog dawb, xim av thiab dub.
Thib ob, cov ntaub nplaum kub kub tuaj yeem muab faib ua ntau hom raws li hauv qab no raws li ntau yam nplaum.
- 1. Silicone nplaum
Silicone kua nplaum yog qhov zoo tshaj plaws tshav kub kub siab rhiab nplaum nplaum.Nws tuaj yeem tiv taus kub ntev txog 260 ℃ thiab luv luv rau 300 ℃.Muaj ob lub tshuab tseem ceeb rau cov kua nplaum silicone uas yog BPO catalytic system thiab platinum catalytic system.BPO system yog pheej yig thiab muaj cua sov zoo dua, tab sis nws yuav volatilize me me molecules ntawm silicon dioxide, uas yuav cuam tshuam rau kev huv ntawm cov khoom.Lub platinum catalyst system muaj qhov kub tsis zoo, tab sis kev huv zoo dua, uas feem ntau yog siv los ua cov khoom siv tiv thaiv silicone.
- 2. Acrylic nplaum
Acrylic kua nplaum muaj ntau yam viscosity zoo huv tab sis tsis zoo cua sov.Lub viscosity tuaj yeem nyob ntawm 1 gram ntawm cov yeeb yaj kiab tiv thaiv mus rau 3000gram ntawm VHB series daim kab xev.Feem ntau, qhov siab dua qhov viscosity, qhov kub tsis kam.Lub iav hloov kub ntawm acrylic nplaum yog li 200 degrees, cov duab ntawm acrylic nplaum dhau 200 degrees tau hloov, thiab viscosity tsawg heev.Tom qab txheej txheej tiav, nws yuav tsum tau kho thiab matured ntawm 40 ° C rau 48 teev.Lub sijhawm kho thiab matured yog txawv nyob rau hauv lub caij ntuj sov thiab lub caij ntuj no, 3-4 hnub nyob rau hauv lub caij ntuj sov thiab txog 1 lub lis piam nyob rau hauv lub caij ntuj no.
Tsawg kub tsis kam yog qhov tsis xws luag ntawm acrylic nplaum hom.Txawm li cas los xij, lub Hoobkas ua kua nplaum tau ua ntau yam kev tshawb fawb los hloov cov kua nplaum.Tam sim no, nws tau tsim qhov kub thiab txias ntawm 250 degrees thiab viscosity ntawm 7-8N acrylic nplaum siab.kub daim kab xev.
Thib peb, raws li cov txheej txheem sib txawv, qhov kub thiab txias tuaj yeem muab faib raws li hauv qab no
- 1. Ib sab siab kub daim kab xev
Ib sab daim kab xev muaj cov cab kuj zoo li Polyimide zaj duab xis, Polyester zaj duab xis, iav ntaub, Teflon iav ntaub los yog PTEFE zaj duab xis thiab coated nrog ib txheej nplaum zoo li silicone nplaum los yog acrylic nplaum.
- 2. Ib sab daim kab xev nrog tso tawm zaj duab xis
Ib sab daim kab xev nrog tso tawm zaj duab xis siv zaj duab xis raws li cov cab kuj coated nrog silicone los yog acrylic nplaum thiab ua ke nrog ib tug tso zaj duab xis los tiv thaiv cov nplaum sab
- 3. Ob sab daim kab xev nrog ib txheej tso zaj duab xis
Muab ob npaug rau sab daim kab xev nrog ib txheej tso zaj duab xis siv zaj duab xis raws li cov cab kuj ob sab coated nrog silicone los yog acrylic nplaum thiab ua ke nrog ib tug tso zaj duab xis
- 4. Sandwich ob sab daim kab xev nrog ob txheej tso zaj duab xis
Muab ob npaug rau sab daim kab xev nrog ob txheej tso zaj duab xis siv zaj duab xis raws li cov cab kuj muab ob npaug rau coated nplaum thiab ua ke nrog ob txheej tso tawm zaj duab xis, ib txheej rau lub ntsej muag sab nplaum, lwm txheej rau sab nraub qaum, nws yog siv los ua cov txheej txheem tuag.
Saum toj no yog kev faib tawm ntawm qhov kub thiab txias tapes raws li txoj kev sib txawv.Yog xav paub ntxiv thiab specification, thovnias ntawm no.Koj yuav pom ntau duaThaum tshav kub kub resistant tapesthiabtuag txiav dawsraws li koj qhov kev thov no ntawm GBS.
