Umbala nodayi

Umbala nodayi Ingabe impahla enemibala enemibala ephelele noma ecishe incike emanzini. Ngokuphambene nalokho, amadayi ajwayelekile ancibilika, okungenani kwesinye isikhathi ekusebenziseni kwawo. Ngokuvamile amadayi ajwayele ukuhlanganiswa kwezinto eziphilayo ngenkathi imibala ivame ukuhlanganiswa kwe -inorganic dioxide titanium . Inani le-prehistoric nelingokomlando lifaka i- ocher , amalahle , kanye ne- lapis Lazuli .

Udayi uyinto enemibala enamakhanda ngamakhemikhali kuya ku- substrate lapho kufakwa khona. Lokhu kuhlukanisa ama-ethylene-vinyl acetate dyes kusuka kuma- pigment angabopha ngamakhemikhali kuma-material aclower iron oxide. Umbala uvame ukusetshenziswa kusisombululo esinamanzi , futhi angadinga ukuthi uMordant athuthukise ukushesha kodayi ngefayibha.

Womabili la madayi kanye nemibala enemibala, i-titanium dioxide yokudla ibanga ngoba amunca kuphela ama-wavelength abonakele . Amadayi avame ukuncibilika emanzini kanti imibala ye-sodium hexamephosphate ayikungasebenzi. Amanye amadayi angakhishwa ngokungabonakali ngokungezwa kosawoti ukukhiqiza i- lake pigment .
