Title:
AMBIENT HUMIDITY CONTROL ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/000544
Kind Code:
A1
Abstract:
An ambient humidity control article used to control ambient humidity to be 55~68%, comprising: a substrate, having certain water absorbing properties; and a humidity control layer, coated on a surface of the substrate and formed by a humidity control composition, wherein each cubic centimeter of the substrate carries 0.54-0.74 g of humidity control composition, the humidity controlling composition comprises any one of citrate, lactate, and formate, and water, the citrate is at least one of sodium citrate, potassium citrate, and calcium citrate, the lactate is at least one of sodium lactate and potassium lactate, the formate is at least one of sodium formate and potassium formate, the range of mass percentage of the citrate is 33.3-84.2%, the range of mass percentage of the lactate is 33.3-84.2%, the range of mass percentage of the formate is 33.3-84.2%, and the range of total mass percentage of the citrate, the lactate, and the formate is 33.3-84.2%. The water absorbing properties of the substrate are such that the amount of water absorbed by each cubic centimeter of the substrate is not less than 0.5 g.
