Epoxy akudziwa aliyense. Mtundu wamtunduwu umatchedwanso zojambulajambula, utola, etc. Ndi mtundu wofunikira kwambiri wa thermosting pulasitiki. Chifukwa cha kuchuluka kwa magulu achangu ndi polar, epoxy retunclules amatha kuwoloka ndi kuchiritsidwa ndi mitundu yosiyanasiyana ya othandizira, ndi katundu wosiyanasiyana akhoza kupangidwa powonjezera zowonjezera zina.

Monga ma thermoseting stun, epoxy stun ali ndi maubwino athupi, zotsatsira zamagetsi, kuphatikiza kwa alkali, kutsutsana mwamphamvu, kukhazikika komanso mtengo wotsika. Ndi imodzi mwazinthu zazikulu kwambiri zopezeka m'magawo a Polymer .. Pambuyo pazaka zopitilira 60, Epoxy Stun wagwiritsidwa ntchito polankhula, makina, amboprosce, zomanga ndi minda ina.

Pakadali pano, Epoxy Tsin imagwiritsidwa ntchito kwambiri pakupanga mafakitale, ndipo zokutira zomwe zimapangidwa ndi gawo lapansi zimatchedwa epoxy tengani zokutira. Amanenedwa kuti epoxy stein ndi zinthu zoteteza zomwe zingagwiritsidwe ntchito kuphimba chilichonse, kuchokera pansi, zida zamagetsi zazing'ono kumagetsi, kuti muwateteze kuwonongeka kapena kuvala. Kuphatikiza pa kukhala cholimba kwambiri, epoxy zokutira nthawi zambiri zimagwirizananso ndi zinthu monga dzimbiri ndi mankhwala osokoneza bongo, motero amadziwika m'makampani ambiri ndikugwiritsa ntchito.

Chinsinsi cha Epoxy Kubala

Popeza epoxy unin ndi m'gulu la madzi polima polymer, zowonjezera ndi zowonjezera ndi zokutira mu thupi lokhala ndi epoxy yophimba. Pakati pawo, nano oxides nthawi zambiri amawongoledwa ngati zokutira ndi mafilimu a epoxy, ndipo oyimilira a Alumium oxide (aluminium Dioxide (ZININ), zinc), ndi nthaka yamphongo. Ndi kukula kwawo kwapadera komanso kapangidwe kake, nano maxisis awa amawonetsa zambiri zapadera zakuthupi komanso mankhwala, zomwe zimatha kukulitsa makina opanga makina komanso anti-corlus a zokutira.

Pali njira ziwiri zazikulu za ma oxide tinthu tating'onoting'ono tomwe timafunikira poteteza ma epoxy:

Choyamba, ndi kukula kwake, kumatha kukwaniritsa bwino ming'alu ya micro-ma pores opangidwa ndi shrinks nthawi yomwe imachiritsidwa ya epoxy slidec yochiritsa ya epoxy, muchepetse njira yotchinga yophimba;

Lachiwiri ndikugwiritsa ntchito kuuma kwamitundu yambiri kuti iwonjezere kuuma kwa epoxy, potero kumalimbikitsa makinawo okutira.

Kuphatikiza apo, kuwonjezera kuchuluka koyenera kwa nano mano oxide kungakulitsenso mawonekedwe omanga mphamvu kwa epoxy zokutira ndikuwonjezera moyo wautumiki wokutira.

Udindo wanano silicaufa:

Mwa zina mwa nanopowder, nano silicon dioxide (Sio2) ndi mtundu wa Kukhalapo kwambiri. Silika Nano ndi mankhwala osavomerezeka omwe ali ndi zitsulo zabwino kwambiri kukana ndi kukana kwa oxidation. Mkhalidwe wake wa molecular ndi ma netiweki atatu okhala ndi [Sio4] Tetrahedron monga gawo loyambirira. Pakati pawo, ma atomu a Oxygen ndi Silicon amalumikizidwa mwachindunji ndi zomangira za Covale, ndipo kapangidwe kake ndi kolimba, motero kumakhala kokhazikika kwa mankhwala, kutentha kwanyengo komanso kukana nyengo, etc.

Nano Sio2 makamaka amatenga gawo la anti-Corossion Filler pakukutira kwa epoxy. Kumbali imodzi, silicon dioxide imatha kudzaza ming'alu yamaliro ndi ma pores omwe amapangidwa munthawi ya epoxy stun, ndikuwongolera kupezedwa kuti kupembedza; Komabe, magulu ogwira ntchito a Nano-sio2 ndi epoxy amatha kupanga mfundo zolumikizirana ndi mankhwala kapena njira, ndikuyambitsa zingwe za SI. Kuphatikiza apo, kuumako kwakukuru kwa nano-sio2 kumatha kupititsa patsogolo kuvala zokutira, potero kumataya moyo wa zokutira.
