Description
Technical field
The present invention relates to a kind of analyzer, particularly relate to a kind of constant temperature and humidity deformeter.
Background technology
For the Inorganic Non-metallic Materials of most of porous, such as gypsum, cement concrete etc., be easy to, because the change of temperature in its environment for use or humidity causes the change of material own dimensions, namely be out of shape.Therefore develop a kind of instrument that can measure material and be out of shape under setting temperature/damp condition, will wide market outlook be had.
At present, following two kinds of methods are usually adopted to realize the mensuration of being out of shape under setting temperature/humidity material in laboratory.Method one: first using deformation measurement testing of equipment material test specimen original dimension, then test specimen is put into climatic chamber, after the temperature and humidity needed for setting, maintenance is carried out to test specimen, take out and repetition measurement to the stipulated time, determining front and back distortion by calculating.Method two: use large-scale climatic chamber or constant temperature and humidity room, first set temperature required and and humidity, then deformation measurement equipment is put into large-scale climatic chamber or constant temperature and humidity room, and after test specimen to be measured is loaded deformation measurement equipment to stipulated time, record deformation data.
For method one, test specimen is when taking out, and the probe temperature residing for it and humidity there occurs change, and be difficult to again accurately location during repetition measurement, its measuring accuracy must be had a greatly reduced quality; Meanwhile, test specimen, taking out, in the process testing and put back to, easily causes the damage of test specimen, also certainly will affect measuring accuracy; Visible the method, testing process is loaded down with trivial details, measuring accuracy is low and cannot realize the original position of material and real-time deformation monitoring.For method two, although simple original position and the real-time deformation monitoring that also can realize material of its testing process, but large-scale climatic chamber/room cost is very high, and high humidity environment easily causes the electronic component surveyed in deformation tester to make moist, or low temperature or hot environment also easily affect serviceability and the precision of electronic component; , there is the shortcoming that with high costs, easy damaged deformation measurement equipment and precision are difficult to ensure in visible the method.
In addition, above-mentioned two kinds of methods, all depend on traditional climatic chamber or constant temperature and humidity room, and this equipment forms primarily of temperature control (heat, freeze) unit, humidifying equipment (comprising humidifier) and circulating fan three part.Three part collaborative works, realize effective control of box interior temperature and humidity; But the especially large-scale constant temperature and humidity system of this constant temperature and humidity system, because cavity space is larger, airflow circulating is bad, humiture space is uneven and fluctuation is larger, such as under normal circumstances, the error of the humidity about 10% that the temperature fluctuation of 0.5 degree Celsius can cause in case, is difficult to the accurate control realizing humidity; In addition, because the deformation time of material is usually longer, therefore the cycle of this experiment is long, and the experiment of single group need take single climatic chamber/room for a long time, causes equipment turnover rate and utilization factor extremely low, and produces huge energy consumption.
