Title: Titanium clad steel sheet for sheathing building and its manufacture
Inventor: YAMAMOTO AKIO
IPC: B24C3/22
Filed: 1989-11-30
Abstract: PURPOSE:To eliminate the need for coating which shows a large deterioration with the lapse of time by producing titanium clad steel sheet wherein the surface diffuse reflection factor is limited and mirror reflection is inhibited. CONSTITUTION:The surface diffuse reflection factor is regulated to 10 -80% which is measured by reflection in the direction of 45 deg. of the surface of titanium and the direction of incidence 90 deg.. In the case of the surface of metal wherein absorption of light on the surface is made extremely little, when the measured surface diffuse reflection factor is made less than 10%, mirror reflection becomes main reflection and this metal is brilliantly looked like a mirror. Therefore this metal can not be utilized for an outer wall and a roof. Further when the measured surface diffuse reflection factor exceeds 80%, the whole mirror reflection is eliminated but the case is caused wherein the direction of micro-mirror reflection is excessively uniformed. This metal can not be utilized for the outer wall and the roof as well because it is brilliantly looked according to an angle.
