Description
The utility model belongs to chemistry teaching demonstration instrument and student experimenting instrument.
At present, along with the needs of the reform of educational system.Pay attention to cultivation that the student is beaten one's brains and starts more and more.In teaching, also more and more higher for this reason to the demand of instruments used for education.Promptly to have demonstrating visual, convenience operation, make the student again when doing experiment, grasp fast, effective, come into plain view, the primary element lecture experiment is the infrastest of chemistry class, for making it that good effect be arranged, " copper zinc original battery demonstrator " (number of accepting 92242285.0) that the inventor declared in November, 92 is that U-shaped pipe salt bridge-type primary element traditional on prolonging with textbook adds special bulb again and makes, and be though it has whole neat appearance, easy for operation, advantages such as intuitive display, but owing to adopt traditional U type pipe salt bridge, its internal resistance does not reduce, thereby power is also very little, bulb is not too bright, and electrolytic sodium chloride makes the phenolphthalein speed that reddens slower.The purpose of this utility model is a kind of low internal resistance of invention, powerful primary element demonstrator.
The purpose of this utility model is achieved in that the agar solution that is full of saturated salt in two mesh plates at regular intervals, and it is logical to make it form salt, and this salt is logical to play a part to isolate two kinds of salt solusions and link up two half cells.Like this, in primary element inside, the path that zwitterion moves is short, and the sectional area that flows is big, thereby has greatly reduced the internal resistance of primary element, has improved power effectively.
The distance of forming between the two logical mesh plates of salt can be different according to different situations, generally be between the 0-30 millimeter, when their distance is zero in particular cases, be to replace with ionic membrane, the function of this ionic membrane is: do not having under the situation of electric field action, it can isolate the solution of two kinds of salt, and when electric field action, the yin, yang ion can orientation pass through.Under the identical condition of mesh cross-sectional area, this moment battery the internal resistance minimum, the power maximum.
According to the logical principle that reduces internal resistance of salt, can suitably increase the area of mesh plate when manufacturing primary element, and reduce the distance between two mesh, can reach like this and both reduce internal resistance, save the purpose of solution again.For manufacturing of mesh plate, also require to make the shared total area in hole big as far as possible, always amassing that tooth is shared is little, be that tooth is wanted carefully, and the area maximum in each hole is no more than 20 square millimeters, promptly in this limited space of cylinder body, enlarges the cross-sectional area that zwitterion moves as far as possible, and don't causing the agar solution of salt to expose, the salt generalist can play the double action of isolating solution and ditch circuit passband like this.
