The present embodiment is implemented on the premise of the technical scheme of the present invention, and a detailed implementation manner and a specific operation process are given, but the protection scope of the present invention is not limited to the following examples.
Example 1
As shown in fig. 1, the embodiment provides a device for testing the anti-condensation capability of a material, which comprises a fixing frame 1, a condensation collection module 2 and a condensation generation module 3. The fixing frame 1 is a rectangular frame with a steel structure, a bottom plate 11 is arranged at the bottom, and mounting rods 12 are arranged in the centers of two sides. The testing device is provided with at least one condensation collection module 2 and a condensation generation module 3, and in this embodiment, three condensation generation modules 3 arranged in parallel are preferably arranged, and the three condensation generation modules 3 are installed at the part, close to the top, of the fixing frame 1. The number of the condensation collection modules 2 is the same as that of the condensation generation modules 3, and the condensation collection modules are placed on the bottom plate 11 and correspondingly positioned below the condensation generation modules 3.
As shown in fig. 2 and 3, each condensation generating module 3 includes a first sealing joint 31, a condensation generating pipe 32, a second sealing joint 33, a water inlet pipe 34, and a water outlet pipe 35. The condensation generating tube 32 is a cylindrical tube, and the outer side wall of the cylindrical tube is wrapped with a layer of a material to be tested, or the cylindrical tube is directly made of the material to be tested, and in this embodiment, the condensation generating tube 32 is preferably directly made of the material to be tested. The material to be tested is PC/ABS material. The condensation generating pipes 32 in the three different condensation generating modules 3 may be made of the same material or different materials. When different materials are adopted, the device can compare different condensation generated amounts among different products; when the same materials are adopted, the device can obtain the average condensation yield of one material, so that the result is more reliable. The condensation generating pipe 32 is also internally provided with a temperature sensor 5 for detecting the temperature in real time, and if the detected temperature is not within the preset temperature or the preset temperature range, the problem is checked in time to be adjusted so as to ensure the accuracy of the experiment. The temperature sensor 5 is a probe sensor, and is inserted into the inner cavity of the condensation generating tube 32 from the second sealing joint 33.
The water inlet pipeline 34 in each condensation generating module 3 is connected with one end of the condensation generating pipe 32 through a first sealing joint 31, and a raised ring with a sealing ring is arranged on the first sealing joint 31 and is used for detachably jogged connection with one end of the condensation generating pipe 32. The first sealing joint 31 is directly fixed to one of the links of the fixing frame 1 by bolts. The water inlet pipes 34 of the three condensation generating modules 3 are all connected to the split-flow pipes 36 positioned on one side of the fixed frame 1, the water inlets of the split-flow pipes 36 are communicated with an external water chiller, and the three water outlets are connected with the water inlet pipes 34. Meanwhile, three independent valves 37 are arranged on the water outlet to control the water flow of the water inlet pipeline 34. The water outlet pipe 35 in each condensation generating module 3 is connected to the other end of the condensation generating pipe 32 through the second sealing joint 33. The second sealing joint 33 is also provided with a raised ring with a sealing ring for detachable fitting connection with the other end of the condensation generating tube 32. The water outlet pipelines 35 of the three condensation generating modules 3 are all connected with three water inlets of a return pipe 38, and the outlet of the return pipe 38 is connected with a water chiller. The existing commercial cold water machine is selected, so that low temperature water enters the condensation generating pipe 32 through the shunt pipe 36 and the water inlet pipe 34, and then flows back to the cold water machine through the water outlet pipe 35 and the return pipe 38, so that the condensation generating pipe 32 maintains constant low temperature.

The method comprises the following specific steps: the bolts on the mounting plate 39 that connect to the mounting bar 12 are removed and the mounting plate 39 is tilted slightly so that the second sealing joint 33 is also tilted slightly. One end of each of the three condensation generating pipes 32 is inserted into three second sealing joints 33. The mounting plate 39 is then restored, and the three condensation generating pipes 32 are simultaneously inserted together in the three first sealing joints 31, and the mounting plate 39 and the mounting rod 12 are re-screwed and fixed.
As shown in fig. 5, the condensation collection unit includes a container bottle 21 having an open top end, and the container bottle 21 is disposed directly below the condensation generation pipe 32.

The funnel 22 is arranged at the opening of the conical flask, the area of the funnel 22 is larger than the downward vertical projection area of the condensation generating pipe 32, and all the dropped condensation is ensured to drop into the funnel 22. The surface of the funnel 22 and the inner side of the container bottle 21 are both subjected to hydrophobic treatment, so that water drops can be better collected. The container bottle 21 can be a fully transparent glass bottle body, and scale marks are arranged on the side wall, so that the collected water quantity is more visual.
When the condensation water generating device is used, low-temperature water is introduced into the condensation production module through the water chiller, and the low-temperature water forms a significant temperature difference between the outer side wall of the tube body and the outside through the condensation generation tube 32, so that condensation water is generated. The water on the outer side wall drops into the lower condensation collection module 2 to gather under the action of gravity. The method comprises the following specific steps: starting the water chiller 4, enabling cooling water to sequentially pass through the water inlet pipeline 34, the condensation generating pipe 32 and the water outlet pipeline 35, and flowing back to the water chiller 4 through the water outlet pipeline 35 to form circulation; waiting for a set time, the amount of water collected in the container bottle 21 is observed and recorded. The user can intuitively display the anti-condensation effect of the material according to the water collection amount of the condensation collection module 2, and can record the time and the water collection amount (by weighing the weight difference of the conical flask before and after water collection) in the form of a table and the like, so that the anti-condensation material is easier to display and publicize. The water temperature adjusting range of the water chiller 4 is 5-20 degrees, the water temperature of the water chiller is generally set to be 5-50 degrees lower than the environment temperature of the testing device, and the water chiller is adjusted and set according to the testing requirement.

One side of the constant temperature and humidity box 6 is transparent and is convenient for observation. The water pipe of the water chiller 4 penetrates into and is connected with the condensation generating module 3 from the outside of the constant temperature and humidity box 6. In the condensation generating module 3, the outside of the first sealing joint, the second sealing joint, the water inlet pipeline and the water outlet pipeline all comprises heat insulation material layers, so that the influence of the external environment on the temperature of cold water is reduced, the condensation is avoided from being generated in the parts except for the condensation generating pipe, and the testing precision and reliability are improved.
