Kodi Epoxy Coatings ndi chiyani

Zovala zopangidwa ndi epoxy zimatha kukhala zigawo ziwiri (zomwe zimatchedwanso kuti zokutira za epoxy) kapena zimagwiritsidwa ntchito ngati ufa wophimba. Zovala ziwiri za epoxy zimagwiritsidwa ntchito pamakina apamwamba kwambiri pagawo lachitsulo. Ndiwo njira yabwino yopangira zokutira ufa m'mafakitale ndi magalimoto ogwiritsira ntchito chifukwa cha kusakhazikika kwawo kochepa komanso kugwirizana ndi mapangidwe amadzi. Kupaka kwa ufa wa epoxy kumagwiritsidwa ntchito kwambiri popaka zitsulo muzinthu zoyera ngati ma heater ndi mapanelo akuluakulu amagetsi. Kupaka kwa epoxy kumagwiritsidwanso ntchito kwambiri poteteza dzimbiri la mapaipi ndi zopangira: m'makampani amafuta ndi gasi, komanso mapaipi amadzi, konkriti yolimbitsanso konkriti kutchula ochepa.

Epoxy ndi copolymer yomwe imapezeka ndi reticulation ya epoxide (resin) ndi polyamine (hardener). Amadziwika bwino chifukwa chomamatira kwambiri, makamaka pazitsulo, kukana kwa mankhwala ndi kutentha, komanso mphamvu yabwino kwambiri yamagetsi. Mapangidwe a epoxy ndi njira yabwino yothetsera zida zambiri zamagetsi ndi zamagetsi (monga: zokutira, chigoba cha solder pama board ozungulira). Pamwambarall zokutira za epoxy ndizokwera mtengo kuposa machitidwe ena monga Alkyd kapena Acrylic, koma amasonyezanso machitidwe apamwamba. Kumbali ina, zokutira za epoxy nthawi zonse zimavutika ndi matabwa a UV. Kufooka kumeneku kumalipidwa ndi kugwiritsa ntchito wosanjikiza woteteza UV kapena topcoat
