Ama-iron oxides asetshenziswa kuma-Coatings aphethwe izinga lokushisa eliphezulu

I-yellow iron oxides ejwayelekile iyimibala efanelekile ye-inorganic ukuze kuthuthukiswe inhlobonhlobo yazo umbala shades ngenxa yezinzuzo ekusebenzeni kanye nezindleko ezinikezwe amandla abo aphezulu okufihla nokungabonakali, isimo sezulu esihle kakhulu, ukukhanya nokukhanya kwamakhemikhali, kanye nentengo encishisiwe. Kodwa ukusetshenziswa kwabo emigqonyeni epholile epholile efana ne-coil coil, i-powder coatings noma amapende okushisa alinganiselwe. Kungani?

Uma ama-iron oxides aphuzi ethunyelwa emazingeni okushisa aphezulu, ukwakheka kwawo kwe-goethite (FeOOH) kuphelelwa amanzi futhi ngokwengxenye kuphenduke i-hematite (Fe2O3), okuyisakhiwo sekristalu se-iron oxide ebomvu. Yingakho i-iron oxide evamile ephuzi ekhona ngaphambi kokwelapha iba mnyama futhi ibe nsundu.

Lolu shintsho lungenzeka kusukela emazingeni okushisa asondele ku-160ºC, kuye ngesikhathi sokuphulukisa, isistimu ye-binder kanye nokwakheka kokumboza ngokwakho.
