Experiment is opened, demonstration teaching aid is can't do without in experimental teaching.In high school chemistry teaching practice, in order to which instructional objective is better achieved, change
Learn Teacher's comprehensive and make various Self-made Realias.But, often due to the limitation of teacher's Self-made Realia, without good straight
Sight, lively displaying function, it has not been convenient to which student improves interesting, do not transfer the enthusiasm of student by observing enhancing impression.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved is to provide a kind of thermochromism temperature indicating to the utility model
Demonstration teaching aid, the change of chemical reaction can be vividly presented in it, intuitively show the characteristic that color changes with temperature, with good
Intuitively, lively displaying function, is easy to the temperature indicating work(of students Reversible Thermochromic Materials and irreversible thermochromic material
Energy.
The utility model is to be addressed above-mentioned technical problem by the following technical programs.
Set on a kind of thermochromism temperature indicating demonstration teaching aid, including measuring cup and thermochromism thermosensitive tag, the outer wall of measuring cup
Thermochromism thermosensitive tag, thermochromism thermosensitive tag includes covering light film and lining paper, and lining recto is provided with water-soluble film, covered
Between light film and water-soluble film be provided with transparent substrate layer, the facial area of transparent substrate layer set up separately be equipped with reversible thermochromic area and
Irreversible thermochromism area, lining recto, which is printed with to be engaged with reversible thermochromic area and irreversible thermochromism area, to be had
The ink picture and text layer of normal temperature value and warning temperature value mark, the back side of lining paper is provided with adhesive layer, thermochromism thermosensitive tag
It is fixed together by the way that adhesive layer is Nian Jie with measuring cup.
Preferably, transparent substrate layer is PE, PP or PET material-structure.
Preferably, lining paper uses fluorescent paper, aluminium-foil paper, speculum metal paper or art paper.
Preferably, reversible thermochromic area be inorganic Reversible Thermochromic Materials, liquid crystal Reversible Thermochromic Materials or
The organic Reversible Thermochromic Materials structure of person.
Preferably, being provided with impermeable priming operation between the lining paper back side and adhesive layer.
Preferably, the openend of measuring cup, which is provided with neck, the neck, sets buckle closure.
Preferably, the neck outer sheath is provided with anti-scald gum cover.
Preferably, measuring cup is plastics or glass material structure.
The beneficial effects of the utility model：
1. thermochromism thermosensitive tag is provided with reversible thermochromic area and irreversible thermochromism area so that thermochromism
Thermosensitive tag possesses the function that color is varied with temperature, and in reversible thermochromic area, color is varied with temperature with reversible
Property, temperature change is in normal temperature area, in irreversible thermochromism area, and color changes with temperature one direction, one direction face
Color change has irreversibility, and temperature change belongs in abnormal temperature interval, thus possesses special temperature indicating alarm flag work(
Energy.When color change, the permeability for covering light film, water-soluble film and transparent substrate layer will not interfere with the information of ink picture and text layer
Marked effect, chemistry teacher, can be by toward warm water is injected in measuring cup, making what observation of students color changed with temperature in demonstration
Characteristic, makes student fully realize Reversible Thermochromic Materials and the temperature indicating function of irreversible thermochromic material, dramatic
Demonstrating effect, widens the popular science knowledge of student, excites great interest.
2. the demonstration teaching aid makes easy, simple to operate, the Scientific Teaching apparatus progress popularization for being suitable as middle school student is pushed away
Wide application.
