Estimating the term…
Disclosed are far-infrared emission powders and resin-coated steel plates with antibacterial activity and far-infrared emission properties. In addition to being 0.9 or higher in emissivity, the far-infrared emission powders are inhibitory against the growth of bacteria, with a pH value of 7.5-10.5 in its saturate aqueous solution. A coating material comprising 5-100 parts by weight of the powder per 100 parts by weight of a resin is coated to a dry thickness of 5-60 μm on an electromagnetic shield steel plate without interruption of the intrinsic electromagnetic shield properties of the steel plate.
A far-infrared emission powder, which is of antibacterial activity with a pH value ranging from 7.5 to 10.5 in its saturate aqueous solution, and shows a far-infrared emissivity of 0.9 or higher.
A resin-coated steel plate with antibacterial activity and far-infrared emission properties, having a resinous coating at a dry thickness of 5 to 60 μm, said resinous coating comprising 5-100 parts by weight of a far-infrared emission powder per 100 parts by weight of a resin, said powder having a pH value ranging from 7.5 to 10.5 in its saturated aqueous solution, and showing a far-infrared emissivity of 0.9 or higher.
