Exemplary of such products are tobacco, musical instruments, electronic equipment, exquisite jewelry, firearms, shipping artwork, and the like, which have specific requirements for the moisture value in the storage environment.
Examples: as shown in fig. 1, the present utility model provides a convenient constant humidity control device, comprising a sealed waterproof and breathable bag 1 containing constant humidity solution 2 and a protective bag 3 sealing and wrapping the sealed waterproof and breathable bag 1; wherein the closed waterproof breathable bag 1 is made of a waterproof breathable film, and the constant-humidity solution 2 comprises a saturated salt solution; the water vapor in the saturated salt solution contained in the sealed waterproof and breathable bag 1 can sequentially enter the surrounding environment through the sealed waterproof and breathable bag 1 and the protective bag 3 so as to regulate and control the humidity of the surrounding environment. As shown in the figure, the sealed waterproof and breathable bag 1 is used for containing saturated salt solution, and the outside of the sealed waterproof and breathable bag is wrapped with the protective bag 3 to protect and support the sealed waterproof and breathable bag 1.
The protection bag 3 may be, for example, a kraft paper bag, and is covered with a waterproof and breathable film on the inner surface thereof, which not only allows water vapor inside to pass through, but also protects the inner contents from the outside in a separated state, thereby preventing other substances inside from leaking.
Further, the sealed waterproof breathable bag 1 and the protective bag 3 are bonded through breathable glue.
The utility model combines the waterproof breathable films into a closed bag structure, and holds saturated salt solution in the bag structure, and the water vapor in the bag structure can freely move to the outside of the bag structure through the waterproof breathable films by utilizing the waterproof breathable effect of the waterproof breathable films and further pass through the protective bag to enter the outside of the constant humidity control device so as to achieve the aim of adjusting the humidity in the external environment of the constant humidity control device. The waterproof breathable film has the advantages that the saturated salt solution in the waterproof breathable film cannot seep out and the protective bag is further protected, so that the waterproof breathable film is high in overall safety, basically cannot leak under the condition of not being impacted by large external force or being touched by sharp objects by mistake, and has high safety no matter whether the waterproof breathable film is placed in a sealed space for storage or transportation and transfer.
The outer protective bag is an air-permeable printed paper bag, the air-permeable printed paper bag and the inner sealed waterproof and breathable bag are bonded through air-permeable glue by adopting a film coating process, so that the integrity of the inner and outer bags is stronger, water vapor can enter the surrounding environment through the protective bag, and the humidity of the surrounding closed environment is kept constant. The protective bag after the film is covered can only enable water vapor to pass through, and water drops and other substances are prevented from permeating, so that the product can be effectively protected from being polluted by saturated salt solution in the protective bag.
In practical production application, when the constant humidity control device is used for producing a finished product, an airtight plastic bag needs to be packaged outside a protective bag, so that water vapor cannot permeate out when the protective bag and the saturated salt solution inside the sealed waterproof and breathable bag are not used, the outer airtight plastic bag is directly torn open when the constant humidity control device is used, the constant humidity control device is started, the constant humidity control device is placed in a target environment, and the saturated salt solution inside the constant humidity control device begins to volatilize water, so that the humidity in the environment reaches a preset humidity value.
It can be appreciated that the technical principle of the utility model is as follows: the three-phase thermodynamic equilibrium is maintained by itself according to the specific saturated salt solution at a specific temperature and pressure. The relative humidity value of the air above the saturated salt solution is kept constant, and the formula proportion of the saturated salt solution is changed, so that the humidity value can be adjusted to achieve a specific humidity range.
In one embodiment, the constant humidity solution further comprises a thickener.
In one embodiment, the thickener is any one or more of alginate, xanthan gum, or pectin.

In one embodiment, the constant humidity value is one of 58%, 62%, 65%,69%, 72%, 75%, 84%. The constant humidity control devices with the constant humidity values of 58%, 62%, 65%,69%, 72%, 75% and 84% can respectively enable the humidity in the closed space in a certain volume to reach the humidity value marked by the humidity control device, and the humidity value is kept unchanged in a certain period of time so as to achieve the constant humidity effect. According to the principle, the constant humidity control device provided by the utility model can not take out the internal solution after the packaging production is completed, namely, the humidity value which can be achieved after the packaging is completed is determined, and the humidity values are marked on the protection bags. After the plastic bag is disassembled, the plastic bag is placed in a preset specific volume space, after a certain working time, the humidity value in the environment where the plastic bag is positioned is maintained within a set target humidity value range, and the environment is maintained for a certain period of time under the condition that the space is not opened or other gases are not introduced.
In one embodiment, the constant humidity solution in the constant humidity control device with the constant humidity value of 69% comprises drinking water, xanthan gum, sodium citrate, sodium chloride, ammonium chloride and citric acid. Illustratively, the constant humidity control device having a constant humidity value of 69% comprises the following components in percentage by weight: 40-70% of drinking water, 0-2% of xanthan gum, 0-0.5% of sodium citrate, 14-40% of sodium chloride, 10-35% of ammonium chloride and 0-1% of citric acid. It will be appreciated that adjusting the percentages of the above components may adjust the humidity value to which they are constant. When in use, a user only needs to select the constant humidity control device with a corresponding constant humidity value according to the storage requirement of the product to be stored.
In one embodiment, the waterproof breathable film has a thickness between 0.15mil and 1.5mil (1 mil = 0.0254 mm). Illustratively, the moisture vapor transmission rate of the waterproof breathable membrane is determined by the type of film and the film thickness used. The overall moisture transport rate is also affected by the volume of the area exposed to the chamber and the solution. The waterproof breathable film pouch has a moisture transfer rate of at least 0.02-0.15 grams per hour, depending on the size of the pouch. It is convenient and quick to reach a constant humidity, with a humidity balance of about 15 minutes to 1 hour, depending on the size of the space in which it is to be placed, and it has been found desirable in the case of cigar boxes containing 4, 6 or 8 cigars to provide a pouch capable of passing at least 0.75 g of water vapour per 24 hours. This will allow the cigar box to be opened five times in an environment with a relative humidity below 40% maintaining the proper humidity in the cigar box.
