Abstract
A kind of humidity indicating label, it comprises providing substrate and comprising the humidity indicating card of inorganic salt particle in stripe-arrangement, and described inorganic salts are respectively lithium chloride, magnesium chloride, magnesium nitrate, sodium bromide, sodium chloride, potassium chloride, potassium nitrate; Be coated with one deck semi-permeable diaphragm above described inorganic salts, when the relative humidity of environment exceedes the moisture absorption point of inorganic salts, deliquescence is to colourless liquid solution gradually for inorganic salts, and the color of display substrate, reaches the object of instruction relative humidity.
Description
Technical field
The utility model relates to a kind of humidity indicating label, specifically, is the humidity indicating label that a kind of change by color indicates humidity to change, and the production method of humidity indicating label.
Background technology
Existing multiple humidity indicator, but major part all comprises developer or metallic ion, it makes color change mainly through chemical change, thus the change of instruction humidity, such as: use cobalt chloride as indicator, be the level change color based on cobalt chloride hydration, but cobalt chloride is known stimulus and toxin; And for example: in U.S. Patent Application Publication No. 2004/0051081, these metallic ions, to provide relative humidity device, but be impregnated in silica-gel carrier by the silica gel material disclosing a kind of copper and bromide dipping, both uneconomical also not environmentally.
Summary of the invention
In order to solve above-mentioned prior art Problems existing, the utility model provides a kind of humidity indicating label, and it makes simple, easy to use; The color and luster accuracy of colour atla is high, economical and practical, and safety non-toxic.
It is as follows that the utility model solves the technical scheme that its technical matters adopts:
A kind of humidity indicating label, it comprises the humidity test paper display card in stripe-arrangement, is inorganic salts crystal grain in display card, plays instruction wetness action.Described inorganic salts are respectively lithium chloride, magnesium chloride, magnesium nitrate, sodium bromide, sodium chloride, potassium chloride, potassium nitrate; One deck semi-permeable diaphragm is coated with above inorganic salts.Described inorganic salts crystal grain, through micronization processes, tiles evenly to facilitate inorganic salts in display card.Described semi-permeable diaphragm is for being made of porous materials, and the only air semi-permeable diaphragm that can penetrate.
The humidity indicating range of humidity indicating label of the present utility model totally 7 numerical value from 16%RH to 99%RH.Described display card is all arranged on the one side of front cover.A label is strip, the little label containing 7 strips, and each little label contains 1 circular viewing area.Test paper of the present utility model adopts nonhazardous inorganic salts display humidity, improves the reproducibility of test paper color and luster, security and the value of environmental protection.Test paper has 7 viewing areas, covers the humidity from 16% to 99%, can once use, and also can separately be used alone.Label back is designed for adhesive sticker, both directly can use, and also can tear back sticky paper and be sticked in exsiccator or region to be measured Long-Time Service, not take up room, and solves conventional moisture detector volume too large, takies the problem of lab space.Humidity test paper forming label of the present utility model is easy, easy to use; The color and luster accuracy of colour atla is high, economical and practical; Safety non-toxic.
The beneficial effects of the utility model are:
1, the utility model adopts inorganic salts physical change that the color of indicating card is changed, and is used to indicate the change of relative humidity.
2, the utility model makes simple, easy to use.
3, the accuracy of this humidity indicating label card is high, economical and practical, safety non-toxic.
Accompanying drawing explanation
Fig. 1 is the vertical view of humidity indicating card of the present invention and the humidity of correspondence.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the vertical view of humidity indicating label of the present invention, it comprises the humidity test paper display card in stripe-arrangement, be inorganic salts crystal grain in display card, the color of label background is from left to right respectively red, orange, yellow, green, blue, grey, purple, indicates relative humidity to be 11% respectively, 33%, 53%, 58%, 75%, 84%, 94%.On indicating label, spread very thin one deck through micronized inorganic salts, relative humidity is 11%, 33%, 53%, 58%, 75%, 84%, and the inorganic salts of 94% correspondence are respectively lithium chloride, magnesium chloride, magnesium nitrate, sodium bromide, sodium chloride, potassium chloride, potassium nitrate.The amount of inorganic salts can cover the color of 1 circular viewing area of label just.Then, on micro mist, plate that one deck is made of porous materials, only the air semi-permeable diaphragm that can penetrate.
When the relative humidity in air is about 16%, the lithium chloride of red indicating label starts deliquescence, forms liquid solution gradually, and at this moment the redness of background starts to highlight, and instruction current relative humidity is not less than 11%.When the relative humidity in air is about 38%, the lithium chloride of red indicating label and the magnesium chloride deliquescence all of orange indicating label, at this moment color that is red and orange indicating label highlights all, indicates current relative humidity to be not less than 33%.When the relative humidity in air is about 53%, the lithium chloride of red indicating label, the magnesium chloride of orange label and the magnesium nitrate of yellow label deliquescence all, at this moment red, the color of orange and yellow indicating label highlights all, and instruction current relative humidity is about 53%.When the relative humidity in air is about 58%, the lithium chloride of red indicating label, the magnesium chloride of orange label, the magnesium nitrate of yellow label and the sodium bromide of green-ticket deliquescence all, at this moment red, orange, the color of yellow and green indicating label highlights all, and instruction current relative humidity is about 58%.When the relative humidity in air is about 80%, the lithium chloride of red indicating label, the magnesium chloride of orange label, the magnesium nitrate of yellow label, the sodium bromide of green-ticket and the sodium chloride of blue label deliquescence all, at this moment red, orange, yellow, the color of green and blue indicating label highlights all, and instruction current relative humidity is about 80%.When the relative humidity in air is about 89%, the lithium chloride of red indicating label, the magnesium chloride of orange label, the magnesium nitrate of yellow label, the sodium bromide of green-ticket, the sodium chloride of blue label and the potassium chloride deliquescence all of grey label, at this moment red, orange, yellow, green, color that is blue and grey indicating label highlights all, and instruction current relative humidity is about 89%.When the relative humidity in air is about 99%, the lithium chloride of red indicating label, the magnesium chloride of orange label, the magnesium nitrate of yellow label, the sodium bromide of green-ticket, the sodium chloride of blue label, the potassium chloride of grey label and the potassium nitrate deliquescence all of purple label, at this moment red, orange, yellow, green, blueness, the color of grey and purple indicating label highlights all, and instruction current relative humidity is about 99%.Specifically refer to table 1:
The color change of the corresponding indicating area of the different relative humidity of table 1
