Abstract:
PROBLEM TO BE SOLVED: To provide a mite-proof sheet which is formed of a moisture-proof sheet comprising a moisture absorbent wrapped in air-permeable sheets and which has a high mite-proof property over a long period even after the moisture-absorbing ability of the moisture absorbent is lost.SOLUTION: The mite-proof sheet includes a moisture-proof sheet 3 including a moisture absorbent 1 wrapped in air-permeable sheets 2a, 2b, and a coating layer 6 applied to the surface of the moisture-proof sheet 3, the coating layer 6 comprising boric acid glass powders 4 dispersed in an organic binder 5, the boric acid glass powders 4 eluting BOat a rate of 1-300 mg/g/hour in water at 20°C.
Abstract:
PROBLEM TO BE SOLVED: To inexpensively provide an antibacterial/antifungal sealing material which is safe for the human health and is excellent in durability of its effect and color fastness. SOLUTION: The sealing material excellent in antibacterial/antifungal properties and color fastness is obtained by adding a soluble glass to the sealing material. The soluble glass essentially comprises zinc, which has an antibacterial/antifungal effect, and preferably has a composition comprising 25-70 wt.% ZnO, 20-70 wt.% B 2 O 3 and 1-25 wt.% at least one chosen from the group consisting of Na 2 O, K 2 O, Li 2 O, CaO, MgO and BaO. The antibacterial/antifungal property can be improved by further adding 0-5 wt.% Ag 2 O. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a stick-preventing material used for the purpose of preventing the adhesion of films with each other or film with a forming roll, etc., in forming of a resin film or sheet or on processing them, and aiming at the prevention of the reduction of transparency by the combination of the resin and stick-preventing material. SOLUTION: This stick-preventing material loaded on the surface of the resin film or sheet is provided by consisting of glass powder having 0.5 μm to 2 mm particle diameter and making the refractive index of the glass powder as the same or close to that of the resin. Here "close to the refractive index of the resin" means that the value of refractive index of the glass powder is made so as to have the same value to at least the two decimal places.
