Abstract:
Provided is a protection processing method for, in a target space in which a sheet material comprising a chlorine-based resin as the main component thereof is disposed or is scheduled to be disposed, making it possible for an inactivation process to be performed by using ultraviolet light even while suppressing the progression of discoloration or deterioration in the sheet material. The target space is a space in which a light source, which emits ultraviolet light exhibiting a light output in a specified wavelength region belonging to the 190-235 nm range, is already disposed or is scheduled to be disposed. This protection processing method has: a step in which a substrate comprising a chlorine-based resin as the main component thereof is attached to an interior surface of a target space or an object surface disposed inside the target space; and a step in which a protective film including a material exhibiting resistance to ultraviolet light is formed on the surface of the substrate.
