Problems solved by technology

For example, the storage humidity of Chinese herbal medicine is about 55-68%. If the ambient humidity is lower than this value, the loss of Chinese herbal medicine will increase and the quality of Chinese herbal medicine will be reduced;
The humidity of certain foods in the dry storage is about 55-68%. If the ambient humidity is lower than this value, the quality of the food will be reduced; if the ambient humidity is higher than this value, the food will be spoiled and even cause food poisoning.
[0003] In order to control the environmental humidity from 55% to 68%, the common way is to use humidity-adjusting silica gel to adjust the humidity of the environment, but the use of humidity-adjusting silica gel does not meet the requirements of green environmental protection products.

Embodiment 1

[0022] figure 1 It is a structural schematic diagram of the environment humidity regulating article in the first embodiment.

[0023] Such as figure 1 As shown, the environment humidity regulating article 10 of the first embodiment is used to regulate and control the environment humidity at 55-68%. The environmental humidity regulating article 10 includes a substrate 11 and a humidity-conditioning layer 12 coated on the surface of the substrate 11 .

[0024] The substrate 11 has a certain water absorption performance, and the water absorption performance of the substrate is not less than 0.5 grams of water per cubic centimeter. The material of the base material is any one of paper material, cotton cloth, chemical fiber material, non-woven fabric, felt, and porous plastic. In the first embodiment, the base material is cotton wood pulp paper among the paper materials. The water absorption performance of the cotton wood pulp paper is not less than 0.8 grams of water per cubic...

Embodiment 2

[0030] figure 2 It is a structural schematic diagram of the environment humidity regulating article in the second embodiment.

[0031] Such as figure 2 As shown, the environmental humidity regulating article 20 of the second embodiment includes a substrate 21 , a humidity-conditioning layer 22 coated on the surface of the substrate 21 , and a wrapping bag 23 for accommodating the substrate 21 .

[0032] The substrate 21 has a certain water absorption performance, and the water absorption performance of the substrate is not less than 0.5 grams of water per cubic centimeter. The material of the base material is any one of paper material, cotton cloth, chemical fiber material, non-woven fabric, felt, and porous plastic. In the first embodiment, the base material is cotton cloth. The water absorption performance of the cotton cloth is that the water absorption per cubic centimeter of the substrate is not less than 0.8 grams, and the water retention performance is that the wat...

Embodiment 3

[0041] In the third embodiment, for the same structures as those in the first embodiment, the same symbols are used and the same descriptions are omitted.

[0042] The humidity-conditioning layer 12 is composed of a humidity-conditioning composition. The moisture conditioning composition comprises lactate and water. The lactate is sodium lactate, and the mass fraction range in the composition is 33.3-84.2%.

[0043] The purity of sodium lactate is not less than 99.9%. Water is deionized water.

[0044]0.74 grams of humidity conditioning composition was loaded per cubic centimeter of substrate.

Description

technical field [0001] In particular, the present invention relates to an environmental humidity regulating article. Background technique [0002] "Humidity" is an important factor affecting product packaging and storage shelf life in all walks of life. Every product requires a reasonable humidity range for storage. For example, the storage humidity of Chinese herbal medicine is about 55-68%. If the environmental humidity is lower than this value, the loss of Chinese herbal medicine will increase and the quality of Chinese herbal medicine will be reduced. The humidity of certain foods in the dry storage is about 55-68%. If the ambient humidity is lower than this value, the quality of the food will be reduced; if the ambient humidity is higher than this value, the food will be spoiled and even cause food poisoning. [0003] In order to control the ambient humidity to 55%-68%, the common method is to use humidity-regulating silica gel to adjust the humidity of the environmen...
