PET high-temperature tape thiab PTFE high-temperature tape
Cov kab xev yog tsim los ntawm ob ntu los ntawm ob ntu: substrate thiab siab-rhiab roj hmab.
Kab lus no qhia txog ob lub substrate khoom: PET, thiab Suav lub npe yog polyphylebenate ethylene glycol, hu ua polyester, thiab nws melting point yog 250-255 degree C. PET cov ntaub ntawv kuj zoo rau hnav-resistant thiab tshuaj tiv thaiv; PTFE, Suav lub npe hu ua polyfluorolythery, feem ntau hu ua tshwj xeeb (hlau) fluoron, nws melting point yog hais txog 327 degree C. Qhov saum npoo ntawm PTFE cov ntaub ntawv yuav ua tau heev tsawg thiab du.
Txhawm rau kom ua tiav qhov kub tsis kam, coated silicon -sensitive kua nplaum ntawm lub substrate.
Qhov kub tsis kam ntawm PET high-temperature daim kab xev tuaj yeem ncav cuag li 204 ° C, thiab qhov kub tsis kam ntawm PTFE high-temperature daim kab xev tuaj yeem ncav cuag li 260 ° C.
Tus neeg sawv cev 3M PET high-temperature daim kab xev muaj 8991 thiab 8992, uas tuaj yeem siv rau qhov nyuaj nto stitching xws li high-temperature hmoov txau, tiv thaiv ib ntus ntawm qhov kub-kub ib puag ncig, thiab daim ntawv kho silicon. 3M tus neeg sawv cev PTFE siab-temperature daim kab xev muaj 5480, 5481, 5490, 5491, uas tuaj yeem siv rau kev tshem tawm kub, txheej / luam ntawv chais, thiab kev tiv thaiv kub seals.
Qee qhov kev siv kub-kub kuj tsis pub siv cov organic silicon siab rhiab heev. PET tapes uas yog coated nrog high-temperature roj hmab-sensitive kua nplaum nrog 3M 875 thiab 876, qhov kub tsis kam yog 177 degree C. Nws tuaj yeem siv rau lub tshuab nqus tsev kub txheej txheej txheej txheem. Lub hnab ntim khoom.
