Inorganic Pigments Nrog Zoo Photostability

Nyob rau hauv kev npaj ntawm inorganic pigment molecules, hlau cations thiab non-metallic anions yog teem nyob rau hauv ib tug array daim ntawv, thiab qhov kev npaj no tsis tso cai rau cov pigments yaj nyob rau hauv cov kuab tshuaj thiab plastics. Piv txwv li, pigments xws li hlau oxide daj, dub, liab, thiab xim av xim av.
Feem ntau, inorganic pigments yog crystals ntawm hlau compounds (feem ntau oxides). Cov hlau hloov pauv tau sib txuas cov hluav taws xob ntawm D orbitals - thaum cov hlau txuas nrog atomic pawg, qhov no yuav ua rau D orbitals "sib cais" rau hauv ob theem zog. Cov electrons hauv cov orbitals tuaj yeem nqus tau lub zog thiab txav mus los ntawm ob theem zog - qhov sib txawv ntawm lub zog ntawm lub zog txiav txim siab lub wavelength ntawm lub teeb absorbed.
Nyob rau tib lub sijhawm, pigments tuaj yeem yog cov organic lossis inorganic, thiab cov pigments inorganic yog optimized. Qhov no yog vim lawv zoo li ci ntsa iab thiab ruaj khov dua, thiab cov khoom siv no muaj cov thermal zoo thiab cov duab ruaj khov. Qhov thib ob, cov xim no tuaj yeem yuav ntawm tus nqi qis.
