2, nkesa nha nha nha nha nke titanium dioxide kwụsiri ike, melite mgbasa nke titanium dioxide na ike mkpuchi

The urughuru size nkesa nke titanium dioxide bụ keukwu index, nke kpọrọ ihe na-emetụta Njirimara nke pigmenti na ngwaahịa ngwa titanium dioxide.Ya mere, mkparịta ụka nke ikpuchi ike na mgbasa nwere ike nyochaa ozugbo site na nkesa nha nha.
