Kodi epoxy fiberglass ndi chiyani?

Zinthu Zopangidwa ndi Gulu
Epoxy fiberglass ndi chinthu chophatikizika, chomwe chimapangidwa makamaka ndi epoxy resin ndiulusi wagalasi. Zinthuzi zimaphatikiza mphamvu zomangira za epoxy resin ndi mphamvu yayikulu ya ulusi wagalasi ndi mphamvu zabwino kwambiri zakuthupi ndi zamakemikolo. Epoxy fiberglass board (fiberglass board), yomwe imadziwikanso kuti FR4 board, imagwiritsidwa ntchito kwambiri pakugwiritsa ntchito makina, zamagetsi ndi zamagetsi ngati zinthu zoteteza kwambiri kapangidwe kake. Makhalidwe ake ndi monga mphamvu zapamwamba zamakina ndi dielectric, kukana kutentha ndi chinyezi bwino, komanso mitundu yosiyanasiyana komanso njira zosavuta zophikira. Kuphatikiza apo, mapanelo a epoxy fiberglass ali ndi mphamvu zabwino kwambiri zamakina komanso kuchepa kochepa, ndipo amatha kusunga mphamvu zapamwamba zamakina m'malo otentha apakati komanso mphamvu zamagetsi zokhazikika m'malo otentha kwambiri. Epoxy resin ndi imodzi mwa zigawo zazikulu za epoxy.mapanelo a fiberglass, yomwe ili ndi magulu achiwiri a hydroxyl ndi epoxy omwe amatha kuchitapo kanthu ndi zinthu zosiyanasiyana kuti apange mgwirizano wolimba. Njira yophikira ya ma epoxy resins imapitilira kudzera mu reaction yowonjezera mwachindunji kapena ring-opening polymerization reaction ya magulu a epoxy, popanda madzi kapena zinthu zina zofooka zomwe zimatulutsidwa, motero zimasonyeza kuchepa kochepa kwambiri (zosakwana 2%) panthawi yophikira. Dongosolo la epoxy resin lophimbidwa limadziwika ndi makhalidwe abwino kwambiri amakina, kumamatira mwamphamvu komanso kukana mankhwala bwino. Ma panel a fiberglass a Epoxy amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikiza koma osati kokha kupanga zida zamagetsi zamagetsi za SF6 zamphamvu kwambiri, zowonjezera-zokwera kwambiri, ma casings ophatikizika a ma transformer amakono, ndi zina zotero. Chifukwa cha mphamvu zake zabwino kwambiri zotetezera kutentha, kukana kutentha, kukana dzimbiri komanso mphamvu zambiri komanso kuuma, ma panel a epoxy fiberglass amagwiritsidwanso ntchito kwambiri mu ndege, makina, zamagetsi, magalimoto ndi mafakitale ena.
Ponseponse, epoxy fiberglass ndi chinthu chopangidwa ndi zinthu zambiri chomwe chimaphatikiza mphamvu zomangira za epoxy resin ndi mphamvu yayikulu yafiberglass, ndipo imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zomwe zimafuna mphamvu zambiri, mphamvu zambiri zotetezera kutentha, komanso kukana kutentha.
