Abstract
The utility model relates to a melting solidification experiment device for the hypo, comprising a test tube and a water bath cup. The utility model is characterized in that a rubber neck ring is sheathed on the neck of the test tube; the test tube passes through the hole of a water bath cup cover and is inserted in the water bath cup; the rubber neck ring is hung on the water bath cup cover. Simultaneously, the utility model is provided with a low pressure resistance wire which is positioned in the water bath cup and under the test tube. The both ends of the resistance wires are lead out through the wiring terminals fixed on the water bath cup cover. If the utility model with simple operation, high safety for use and favorable experiment effect is matched with an adjustable voltage-stabilized source with common low voltage to use, the utility model can be used for improving successful rate of a melting solidification experiment for the hypo.
Description
The utility model relates to the device that a kind of education experiment is used.More particularly, be a kind of be used for the carrying out fusing of hypo, apparatus of solidification experiments.
Also there is not a kind of hypo fusing solidification experiments apparatus that teaching or student experimenting are used that is specifically designed in the prior art.For fusing, the process of setting of observing hypo, traditional method is with spirit lamp the water-bath cup to be heated, and control bath temperature by the position of moving smart wine lamp.This mode, not only operation inconvenience, and also water temperature is difficult to control, and experiment success rate is low.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of fusing solidification experiments device of hypo is provided, and to simplify the operation, improves the success ratio of hypo fusing setting test.
The purpose of this utility model is achieved through the following technical solutions.
The utility model comprises test tube and water-bath cup, its architectural feature is, on the neck of described test tube, sheathed rubber neck ring, test tube passes lid hole, the insertion water-bath cup of bathing bowl cover, and be suspended on by the rubber neck ring and bathe on the bowl cover, what be provided with simultaneously has a low resistance silk that is positioned at water-bath cup, test tube below, and draw by the binding post that is fixed on the bath bowl cover at the resistance wire two ends.
Compared with the prior art, the utility model is simple to operate, safe in utilization, is used common low pressure adjustable stabilized voltage supply, its water temperature is easily controlled, the having a narrow range of temperature of water temperature and hypo, and the temperature of solidification of hypo has long the surveyed time, thereby test effect is good, success of the test rate height.
Fig. 1 is the utility model structural representation.
Fig. 2 bathes cup supporting structure synoptic diagram for the utility model.
By the following examples, in conjunction with the accompanying drawings, the utility model is further described.
Embodiment:
Referring to Fig. 1, on the neck of test tube 1, sheathed rubber neck ring 3, test tube 1 passes lid hole, the insertion water-bath cup 2 of bathing bowl cover 4, and be suspended on by rubber neck ring 3 and bathe on the bowl cover 4, what be provided with simultaneously has a low resistance silk 5 that is positioned at water-bath cup 2, test tube 1 below, and draw by the binding post 6 that is fixed on the bath bowl cover 4 at resistance wire 5 two ends.Choose the resistance wire that resistance is 5 Europe in the present embodiment.Stirrer 11 among Fig. 1 inserts test tube 1 when needed and stirs.
Referring to Fig. 2, constitute a bath cup support by base 7 and strut 8, the upper end of strut 8 connects firmly rubber top board 9, offers thermowell 10 on the rubber top board 9.Three jacks are chosen two wantonly as required.
Bathe the cup support and be used for when experiment, placing the bath cup, and insert solid thermometer.
Experimental technique:
1, experimental provision
Bathe cup and place on the bath cup support, thermometer is fixed by thermowell, and is suspended in test tube respectively and bathes in the cup.
2, experimental procedure
(1), connect the low pressure adjustable stabilized voltage supply, voltage is adjusted to 12 volts.
(2), when the hypo temperature reaches 35 ℃, regulation voltage to 8 volt, and, every temperature of one minute record.
(3) after hypo all melts, continue heating, whether when temperature was increased to 52 ℃ of left and right sides, deenergization allowed liquid hypo begin to cool down, and examines its process of setting, see just in time opposite with its fusion process.
Points for attention:
1, the water of bathing in the cup is wanted an amount of (being advisable about 180 grams).
2, the amount of hypo is wanted suitably, want fully to flood the Bo Lipao of thermometer, will be before the experiment the hypo pulverize, the powdered graphite (occurring the supercooled state phenomenon when preventing to cool off) of some swarfs (it is more even that hypo is heated) and trace will be put in the inside, and will compress the hypo powder.
3, the key of this Success in Experiment is a regulation voltage, makes the temperature of water temperature and hypo be more or less the same.Just begun the temperature difference and be controlled at 5 ℃ with interior better, during near fusing, the temperature difference is controlled at 2 ℃ with interior better.Therefore, to come regulation voltage according to the registration difference of two thermometers in the experimentation.Generally beginning to be transferred to 12 volts or 14 volts, is 6 volts to 8 volts before the fusing, is 12 volts after the fusing.
4, the glass envelope of thermometer will stir in the heating process (agitation as appropriate during fusing) near test tube wall (contact), prevents that the hypo powder from big space and hypo powder occurring along moving on thermometer or the test tube wall.
Claims (2)
1, a kind of fusing solidification experiments device of hypo, comprise test tube (1) and water-bath cup (2), it is characterized in that, on the neck of described test tube (1), sheathed rubber neck ring (3), test tube (1) pass lid hole, the insertion water-bath cup (2) of bathing bowl cover (4), and are suspended on the bath bowl cover (4) by rubber neck ring (3), what be provided with simultaneously has a low resistance silk (5) that is positioned at water-bath cup (2), test tube (1) below, and draw by the binding post (6) that is fixed on the bath bowl cover (4) at resistance wire (5) two ends.
2, hypo fusing solidification experiments device according to claim 1 is characterized in that, is made of base (7) and strut (8) and bathes the cup support, and the upper end of strut (8) connects firmly rubber top board (9), offers thermowell (10) on the rubber top board.
