Definitions
- the disadvantage of such a system is that the certain, limited amount of the desiccant inside the bag corresponds only to a certain, limited moisture absorption capacity. If the amount of the desiccant is exhausted due to reaching the maximum absorption capacity for moisture (i.e. essentially water), the remains Desiccant bag ineffective Further moisture or water absorption is impossible and the guarantee of a constant, in particular reduced humidity in one Enclosed gas space surrounding the desiccant bag is not possible.
- the object of the invention is therefore to provide a device for reducing the moisture content of a closed gas space surrounding the device or for setting a defined relative air humidity, which avoids these disadvantages of the drying devices known in the prior art.
- the need for processing or prior storage in a closed gas space surrounding the device with reduced moisture content or processing under extremely time-limited conditions should be avoided.
- the matrix is preferably sheet-like. This means that the spatial configuration of this matrix in the three dimensions (height,
- the width or length of the sheet-like matrix are not critical parameters, but can meet the respective needs of practice be adjusted.
- the minimum value of the width for a practical handling of the sheet-like matrix can be seen as approximately 2 mm.
- the width of the sheet-like matrix is preferably between approximately 1 and approximately 50 cm, particularly preferably between approximately 2 and approximately 10 cm.
- Rosin esters and hydrogenated esters of rosin, hydrocarbon resins, etc. which are optionally added to the matrix in such amounts until the desired pressure-sensitive adhesive property is achieved.
- the special matrix materials must be taken into account when choosing the amount of tackifier. The others can do this too
- the drying device can also contain a support layer. It has the purpose of giving the drying device a higher dimensional stability. This can be the case, for example, when the matrix containing the desiccant is itself too flexible for practical handling, for example due to its very small thickness or relatively high elasticity.
- the support layer can optionally cover the matrix or even be identical to the layer permeable to water vapor.
- the support layer can be located on one side or on both sides of the sheet-like matrix. Suitable materials for such a support layer are materials known to the person skilled in the art, for example PET film, polyethylene, polypropylene, paper, nonwovens, etc.
- the drying device prefferably contains a layer which fulfills at least two of the technical functions of a water vapor permeable layer, support layer and protective layer.
- a desiccant-containing matrix with a relatively high desiccant content must be used, whereby the desiccant should also have a high water absorption capacity.
- Such a high desiccant content in active form) can make up, for example, about 50 to 70% of the total weight of the desiccant matrix.
- Example: 0.2 atm and / or an artificially generated circulating air facilitate the selected activation conditions (for example: temperature, duration, radiation intensity).
- the use of these additional measures can also result in the fact that, in the case of activation at elevated temperature, this does not have to be above 100 ° C., the boiling point of the water under normal conditions, but may already be around 60 to 80 ° C.
- the regenerable desiccant When activated, the regenerable desiccant changes into its active form, in which it has the ability to absorb moisture or water.
