The shown color changes of the test paper provided by the invention are different when the test paper is in contact with the same substance.
Description
Technical field
The present invention relates to detection field, particularly relate to a kind of test paper of negative testing.
Background technology
Test paper, refers to a class paper that is impregnated with chemicals, that exist by Cucumber in its color change detecting liquid or gas.Such as the multiple acid base indicator of pH test paper floods, and is used for checking the acidity of material or alkalescence, or the approximate pH of solution to be measured; Different colors will be shown for different pH value.For another example with the test paper of potassium iodide dipping, can in order to check sulfide, when there is sulfide, test paper can variable color.
Visible, current test paper be all according to contact material difference and show different colors.
Summary of the invention
The present invention proposes a kind of test paper of negative testing, and when the material contacted is identical, test paper can show different color changes.
In order to solve the problem, the invention provides a kind of test paper of negative testing, comprising:
Base material;
First material, attachment is on the substrate; In the described test paper of different model, the type of the first material accompanying on described base material or content difference;
Described first material can change color when running into the second material, and described first material script color that is dissimilar or content is identical, and the color become when running into the second identical material is different; Or described first material color difference originally that is dissimilar or content, the color become when running into the second identical material is identical; Or described first material color difference originally that is dissimilar or content, the color become when running into the second identical material is still different.
Alternatively, described test paper also comprises:
Diaphragm, covers described first material on described base material.
Alternatively, described base material comprises paper, textile.
Alternatively, described first material attachment all or part of region on the substrate.
Alternatively, described second material is liquid, solid-state or gaseous state.
Alternatively, described base material is filter paper or textile;
Described first material attachment refers on the substrate:
Described base material crosses by the solution impregnation of described first material.
Alternatively, described first material attachment refers on the substrate:
Described base material is pasted or is coated with described first material.
Alternatively, the shape that described first material is formed on the substrate comprises following any one or its combination in any:
Powdered, block, strip, character shape, bar code shape, irregularly shaped, arbitrary graphic.
Alternatively, described first material attachment refers on the substrate:
Described base material adopts the content of the ink printing containing described first material.
Alternatively, described first material attachment refers on the substrate:
The manufacture of described base material or coating material comprise described first material.
The present invention can meet in some cases, test paper shows the needs of different color changes according to material own or the difference of carrying material, in test paper, such as increase the material of meeting water or alcohol variable color, the color change that the material of the test paper interpolation of different model produces is different, can by the test paper of different model corresponding different article/information respectively, user can by putting into predetermined substance by test paper, such as put into the color change that the such Common materials of water/alcohol just can know test paper, thus learn article/information that each test paper is corresponding; Be contacted with different material by same test paper in prior art, the present invention then breaches Traditional Thinking, can contact with the test paper of different model with a kind of material conversely, distinguishes test paper thus can obtain article/information corresponding to test paper.
Other features and advantages of the present invention will be set forth in the following description, and partly become apparent from instructions, or understand by implementing the present invention.Object of the present invention and other advantages realize by structure specifically noted in instructions, claims and accompanying drawing and obtain.
Accompanying drawing explanation
Accompanying drawing is used to provide the further understanding to technical solution of the present invention, and forms a part for instructions, is used from and explains technical scheme of the present invention, do not form the restriction to technical solution of the present invention with the embodiment one of the application.
Fig. 1 is the schematic diagram of the test paper of the negative testing of embodiment one.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in detail.
It should be noted that, if do not conflicted, each feature in the embodiment of the present invention and embodiment can be combined with each other, all within protection scope of the present invention.
The test paper of embodiment one, a kind of negative testing, as shown in Figure 1, comprising:
Base material 11;
First material 12, attachment is on the substrate; In the described test paper of different model, the type of the first material accompanying on described base material or content difference;
Described first material can change color when running into the second material, and described first material script color that is dissimilar or content is identical, and the color become when running into the second identical material is different; Or described first material color difference originally that is dissimilar or content, the color become when running into the second identical material is identical; Or described first material color difference originally that is dissimilar or content, the color become when running into the second identical material is still different.
Such as, described test paper comprises 14 models, the material of the first included material to be potential of hydrogen be respectively 1 ~ 14 (permission certain error); When being put into by the test paper of different model after in reindeer moss solution (that is: the second material), different colors can be presented.For another example, anhydrous cupric sulfate was white originally, and meet water in blue, if the content of contained anhydrous cupric sulfate is different in the test paper of different model, the blueness presented also can be variant.The first material in the test paper of different model is for another example respectively: anhydrous cupric sulfate (was white originally, meet water in blue), waterless cobaltous chloride (was mazarine originally, meet water pinkiness), sodium peroxide (be faint yellow originally, and met water in white).
