Nā Pigment Pearlescent

Loaʻa nā puaʻa momi kuʻuna me kahi ʻāpana metala oxide kiʻekiʻe-refractive-index i uhi ʻia ma luna o kahi substrate alohilohi, haʻahaʻa-refractive-index substrate e like me natural mika. Hoʻopili ʻia kēia ʻano layering me ka māmā e hana i nā ʻano hoʻohālikelike a me ka luku ʻana i nā kukui i ʻike ʻia a i hoʻouna ʻia, a mākou e ʻike ai. kala like 'ole.

Ua hoʻonui ʻia kēia ʻenehana i nā substrate synthetic ʻē aʻe e like me ke aniani, alumina, silica a me ka mica synthetic. Loaʻa nā hopena like ʻole mai ka satin a momi luster, e alohilohi me nā waiwai chromatic kiʻekiʻe, a me nā hiʻohiʻona o ka waihoʻoluʻu hue, e hilinaʻi hou i ka hoʻolālā kikoʻī (ke ʻano o ka metala oxide, ka mānoanoa o ka papa, ka puʻunaue ka nui o nā ʻāpana, ka lākiō hiʻohiʻona o nā substrates, etc.).

Ke uhi ʻia me ka titanium dioxide, ʻokoʻa kēia mau puaʻa interference mai ke kālā, gula, ʻulaʻula, uliuli a me ka ʻōmaʻomaʻo. Hoʻohui ʻia, ʻo nā substrate i uhi ʻia i ka hao oxide ka hopena i kahi hopena luster chromatic hohonu. ʻO nā palena nui o nā hopena momi ka nele o ka opacity a me ka māmā haʻahaʻa haʻahaʻa ma waena o nā kihi specular a me lalo.
