Anticorrosive pigmenti
Ọdịnihu omume na anticorrosive pigments bụ inweta chromate free na arọ metal free pigmenti na ịga na ntụziaka sub-micron na nanotechnology mgbochi corrosive pigments na smart mkpuchi na corrosion-sensing. Ụdị mkpuchi smart a nwere microcapsules nwere ihe ngosi pH ma ọ bụ ihe mgbochi corrosion ma ọ bụ/na ndị na-agwọ onwe ya. Shei nke microcapsule na-akụda n'okpuru ọnọdụ pH bụ isi. Ihe ngosi pH na-agbanwe agba ewepụtara ya na microcapsule yana ihe mgbochi corrosion na / ma ọ bụ ndị na-agwọ onwe ya.
