Nsalu yagalasi imapangidwa ndi ulusi wagalasi ndikuwomba ngati nsalu, ndipo makulidwe ake ndi 130um mumtundu woyera.Chovala chagalasi chimakhala ndi mphamvu zolimba kwambiri komanso kukana misozi zomwe zitha kugwiritsidwa ntchito ngati kukulunga kapena kukonza thiransifoma, Njinga, batire ya lithiamu kapena kukonza zida zanga.
Nsalu yagalasi ya fiber imapangidwa ndi Teflon yotetezedwa ndikukutidwa ndi zomatira za silikoni pambuyo pa chithandizo cha nanochemical.Ili ndi zotsutsana ndi ndodo, kutentha kwambiri komanso kukana kwa mankhwala, zomwe zimapereka yankho lolimba kwambiri pamakina opaka ndi kusindikiza kutentha.Makulidwe ambiri a nsalu ya galasi ya Teflon ndi 80um ndi 130um, makulidwe ena apadera ngati 50um, 150um kapena 250um amathanso makonda malinga ndi pempho lamakasitomala.
PTFE Film zigwirizana kuyimitsidwa PTFE utomoni ndi akamaumba, sintering, kuzirala mu akusowekapo.Ili ndi zinthu zabwino kwambiri za dielectric, kukana kukalamba komanso kukana kwa dzimbiri zomwe zimagwiritsidwa ntchito nthawi zambiri kusindikiza ulusi, ma doping a mapaipi, ma plumbers ndi kukulunga.Pali mitundu itatu ya zosankha, zomwe ndi zoyera, zofiirira ndi zakuda.
Chachiwiri, matepi otentha amatha kugawidwa m'mitundu yosiyanasiyana monga pansipa molingana ndi zomatira zosiyanasiyana.
- 1. Zomatira za silicone
Guluu wa silicone ndiye zomatira zabwino kwambiri zolimbana ndi kutentha.Imatha kukana kutentha kwautali mpaka 260 ℃ ndi kutentha kochepa mpaka 300 ℃.Pali makina akuluakulu awiri a silicone glue omwe ndi BPO catalytic system ndi platinamu catalytic system.Dongosolo la BPO ndi lotsika mtengo ndipo limakhala ndi kukana kutentha kwabwino, koma lidzasokoneza mamolekyu ang'onoang'ono asilicon dioxide, omwe angakhudze ukhondo wa chinthucho.Dongosolo lothandizira platinamu limakhala ndi kukana kutentha kosakwanira, koma ukhondo wabwino, womwe nthawi zambiri umagwiritsidwa ntchito popanga filimu zoteteza silicone.
- 2. Zomatira za Acrylic
Akriliki guluu ali osiyanasiyana mamasukidwe akayendedwe zabwino ukhondo koma osauka kukana kutentha.Kukhuthala kumatha kuchoka pa 1 gramu ya filimu yoteteza mpaka 3000gram ya tepi ya VHB.Nthawi zambiri, kukhathamiritsa kwamphamvu kwambiri, kumapangitsanso kutentha kwambiri.Kutentha kwa magalasi a zomatira za acrylic ndi pafupifupi madigiri 200, mawonekedwe a zomatira za acrylic kuposa madigiri 200 asintha, ndipo mamasukidwe ake ndi otsika kwambiri.Mukamaliza zokutira, ziyenera kuchiritsidwa ndi kukhwima pa 40 ° C kwa maola 48.Nthawi yochiritsidwa ndi yokhwima imakhala yosiyana m'chilimwe ndi yozizira, masiku 3-4 m'chilimwe komanso sabata imodzi m'nyengo yozizira.
Kutsika kwa kutentha kukana ndi vuto la mtundu womatira wa acrylic.Komabe, fakitale ya guluu yachita kafukufuku wambiri kuti isinthe guluu.Pakali pano, yapanga kutentha kwa madigiri 250 ndi kukhuthala kwa 7-8N acrylic zomatira pamwamba.tepi ya kutentha.
Chachitatu, molingana ndi mawonekedwe osiyanasiyana osanjikiza, kutentha kwakukulu kumatha kugawidwa monga pansipa
