MINUS ION-GENERATING SHEET

摘要

PROBLEM TO BE SOLVED: To provide a resin sheet-type minus ion-generating material which can efficiently generates minus ions at a low cost. SOLUTION: Calcium carbonate of 70 to 92 wt.%, carbon of 6 to 20 wt.% and calcium hydroxide of 2 to 15 wt.% are contained in polyolefin resins, and furthermore inorganic particles having water content of less than 1% are also included at a rate of 1.0 to 25 g/m<2> . The minus ion-generating resin sheet which efficiently generates the minus ions is obtained by molding the such resins in sheet.
