We have provided materials for a number of major properties. In the process, we have amassed the know-how in control technolo-gies to make products in a sufficient quantity to extensively cover a large aera, with the least possible variations in color tones between lot(coils).
In addition, we are also able to provide roofing and exterior-execu-tion companies with information required for lot control.
※lot control
Base metal(uncoated)for use as a building material may often come in delicately varied color tones between manufacturing lots. Titanium is no exception. In order to prevent impairment of the class of the whole building by such an element, it is a common practice to use coils(panels)in the order of approximation and gradation in color to make color variations inconspicuous.
Distortion of the material after rolling is small, and the design performance as a roof is maintained.
Rub it away with a sponge or cloth wetted with alcohol, benzene, thinner, or a mixed solution of alcohol and toluene or acetone (in the order of weak to strong agents).
It is important to wipe off with a fresh clean cloth before these solvents get dry.
Such stain can be wiped off with a neutral detergent or soap water in most cases.
Use organic solvents (alcohol, benzene, etc.) if the above does not work.
The above-stated precautions should apply here.
Wipe it off with 5% solution of hydrochloric acid.
Wipe it off with 15% solution of nitric acid.
Such stain can be wiped off with neutral detergent or alkaline detergent in most cases.
If the above does not work, apply an abrasive cleanser over a soft cloth and rub the stained surface with it lightly and uniformly. This may work.
Do not try to use hydrochloric acid, nitric acid or cleanser for removal of stains among the above-mentioned maintenance methods.
When these are used, the coloring layer is so affected that the former state cannot be restored.
Washing with water should be done carefully after the removal of stains according to either of the procedures elaborated above lest the agent used is left unremoved.
