systemΔ T graphing, is tried to achieve specific heat capacity c. to be measured and is realized the specific heat capacity of corrosive liquids and the mensuration of non-corrosiveness specific heat of liquid by above-mentioned improvement.
Description
Art
The utility model relates to a kind of new equipment measuring specific heat capacity, heating wire loss when specifically measuring for current electrothermal way the mensuration corrosive substance specific heat capacity that specific heat capacity device exists, the change of test substance composition cause the defects such as error to propose rational corrective measure, can extended measurements be multiple is corrosive and the specific heat capacity of non-corrosive material, realize measuring the specific heat capacity of corrosive liquids.
Background technology
Specific heat capacity is the important physical amount of reflection material thermal property, and its measurement is one of physical fundamental measurement.The mensuration of specific heat capacity, for the aspect such as development understanding the structure of material, the phase transformation determining material, the qualification purity of material and the exploitation of new forms of energy and new material, all plays an important role.
The method measuring material specific heat capacity is a lot, wherein conventional direct method or title electrothermal way (by electric hot plate directly to the method that testing liquid heats), also exist and be difficult to measure the defects such as common corrosivity (or showing corrosivity when being energized) specific heat of liquid.
Summary of the invention
The utility model object overcomes existing electrothermal way specific heat capacity determinator to be difficult to measure corrosive liquids specific heat perhaps to the very large deficiency such as grade of the evaluated error of corrosive liquids specific heat capacity, the utility model provides a kind of novel specific heat capacity determinator, take electrothermal way as heating means, Q=UIt calculates electric heating with the formula, take anti-corrosion device as heating module, by gathering electric current I, voltage U, time t, the data such as temperature T, utilize formula UIt=cm Δ T+c
systemΔ T graphing, tries to achieve specific heat capacity c to be measured, thus reaches the object can measuring corrosive substance specific heat capacity.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Heating module by traditional electrothermal way direct with exposed, be improved to by the electric calorifie installation containing porphyrize mica powder packaged battery heated filament in glass tube with the heating wire that test substance directly contacts.
Compared with prior art, the beneficial effects of the utility model are: the heating module improving original device, solve the shortcoming that original device is difficult to effectively measure some corrosive liquids specific heat capacities; Be aided with and measure the mixing method that some measures particular matter, the specific heat capacity of energy extended measurements solid, liquid.Such as: sulfuric acid solution, under heating wire power on condition, show corrosive sodium chloride solution etc.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is system construction drawing of the present utility model.
