Detailed Description
In order to make the technical means, the creation features, the achievement of the purpose and the effect of the present utility model easy to understand, the present utility model is specifically described below with reference to the accompanying drawings.
Examples
Fig. 1 and 2 are side and front views, respectively, of a wetness indicator with a wetness indicator.
As shown in fig. 1 and 2, the present embodiment provides a humidity control sheet with a humidity indicator card, which includes a fibrous humidity control sheet 10, a wrapping paper 20, and a humidity indicator card 30.
When the environmental humidity changes, the fiber humidity-regulating sheet 10 can quickly react, and the humidity is balanced by absorbing and releasing the moisture, so that the environmental humidity is stabilized within any one of accurate target humidity values or ranges of 30% -90% RH, and phenomena of wetting, mildew, drying or cracking of stored articles can be avoided. The target humidity value or range of the fibrous humidity control sheet 10 can be adjusted by different formulations, the shape can be selected according to the actual situation, and in this embodiment, the fibrous humidity control sheet 10 is circular.
The wrapping paper 20 wraps the fibrous humidity-controlling sheet 10 and serves as an outer package of the fibrous humidity-controlling sheet 10. In this embodiment, two pieces of wrapping paper 20 are wrapped on both sides of the fibrous humidity-controlling sheet 10, respectively, and the edges thereof are sealed by a heat-sealing process, thereby integrally forming the outer package of the fibrous humidity-controlling sheet 10. Wherein, a certain space is reserved in the outer package for the fiber humidity-controlling sheet 10 to change in volume in the process of moisture absorption and release. In addition, the packing paper 20 preferably adopts Du Laizhi, and has the characteristic of ventilation and reverse osmosis prevention, so that the fiber humidity-controlling sheet 10 can be well prevented from liquid reverse osmosis in the extrusion and moisture absorption and release processes.
A humidity indicator card 30 is attached to the outer surface of the wrapper 20, the humidity indicator card 30 being adapted to display the ambient humidity. In this embodiment, the wetness indicator 30 is in a circular sheet shape, one surface of which is adhered to the outer surface of the wrapper 20 by means of self-adhesive or dispensing, and the other surface of which faces outwards and is provided with a color-changing area 31, a demarcation area 32, and an indication area 33, which are sequentially arranged from the center to the edge, as shown in fig. 2.
Wherein, the humidity indicator is dripped in the color-changing area 31, and the humidity indicator can generate color change along with the change of humidity.
The boundary region 32 serves as a boundary between the color-changing region 31 and the indication region 33, and adopts a dark color different from the humidity-changing color, thereby facilitating the human recognition of the colors of the color-changing region 31 and the indication region 33.
The indication area 33 is used for indicating humidity values corresponding to the color of the color-changing area 31, and includes a plurality of color patch areas and a plurality of humidity values. Each color block area is fan-shaped, the whole color block areas are arranged in a circular ring shape, and a plurality of humidity values are distributed on the outer periphery sides of the color block areas correspondingly.
