Iron oxides Shandisa muKupisa-kuporeswa Coatings

Standard yellow iron oxides ndiwo akakodzera inorganic pigments kugadzira akasiyana siyana ruvara shades nekuda kwezvakanaka mukushanda uye mari inopiwa nehukuru hwavo hwekuvanza simba uye opacity, mamiriro ekunze akanaka, chiedza uye chemikemikari kukurumidza, uye mutengo wakaderedzwa. Asi kushandiswa kwavo mune yakakwirira-yekushisa-yakaporeswa machira senge coil coil, kupfeka hupfu kana stoving pendi ishoma. Sei?

Kana iyo yero iron oxides inoiswa kune yakanyanya tembiricha, yavo goethite chimiro (FeOOH) inopedza mvura uye zvishoma inoshanduka kuita hematite (Fe2O3), inova crystal chimiro chered iron oxide. Ndosaka mwero yero iron oxide iripo isati yarapwa ichisviba nekusviba .

Shanduko iyi inogona kuitika kubva kune tembiricha dziri pedyo kusvika 160ºC, zvichienderana nenguva yekurapa, binder system uye magadzirirwo ekuputira pachayo.
