Abstract
Description
Technical Field
[0001] This utility model belongs to the field of snow melting agent testing technology, specifically relating to a device for rapid evaluation of snow melting agent performance. Background Technology
[0002] Winter brings frequent rain, snow, and freezing weather, causing roads to become slippery after snow and ice accumulate, greatly increasing the risk of traffic accidents. To ensure normal traffic flow, measures must be taken to clear the snow and ice from the roads. Currently, in addition to traditional mechanical snow removal methods, chemical snow removal methods, such as applying de-icing agents, are also a major method. However, the large-scale use of de-icing agents can cause erosion of cement pavements and loosening and peeling of asphalt pavements, leading to a decrease in road quality and service levels. Although environmentally friendly de-icing agents are available, their manufacturing processes are complex, and they are generally expensive, resulting in high snow removal costs. Therefore, de-icing agents with excellent snow-melting performance, low cost, and minimal environmental impact are receiving considerable attention.
[0003] The evaluation standards for de-icing agents in various parts of China are incomplete, and there is no universally effective method. This makes the practical application of de-icing agent products in my country very difficult, especially on highways, where the economic benefits are very low and waste is serious. Therefore, accurately selecting the appropriate type and amount of de-icing agent based on the actual road conditions has become a critical issue that we must solve. In view of this, there is an urgent need for a rapid performance evaluation device for de-icing agents that can quickly and easily screen out agents with better performance, achieve efficient de-icing of ice and snow on roads, and ensure safe and smooth traffic in winter.

[0012] Specifically, the observation window is detachably and sealed to the low-temperature test chamber via a sealing frame.
[0013] Specifically, the sealing frame is connected to the low-temperature test chamber by bolts.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0027] Example 1
[0028] See Figure 1-4 As shown, this embodiment provides a rapid performance evaluation device for de-icing agents, including a low-temperature test chamber 1 and a vacuum pump 4 installed outside the low-temperature test chamber 1 for drawing a vacuum inside the low-temperature test chamber 1. The low-temperature test chamber 1 is provided with a transparent platform 9 for placing snow or ice samples. A shadowless lamp 8 corresponding to the transparent platform 9 is fixedly installed on the inner top of the low-temperature test chamber 1. A control device 7 for controlling the shadowless lamp 8, the vacuum pump 4, and the temperature of the low-temperature test chamber 1 is also provided on the outer top of the low-temperature test chamber 1. An observation window 3 is provided on the front of the low-temperature test chamber 1 to facilitate observation of the snow or ice samples inside the transparent platform 9.
[0029] Specifically, the transparent stage 9 is provided with a row of multiple sets of blind holes 11 with the same depth. Preferably, there are three sets of blind holes 11, which are arranged in order of diameter. The first set has four blind holes 11, the second set has two blind holes 11, and the third set has two blind holes 11. Preferably, the diameter of the blind holes 11 can be adjusted as needed.
[0030] Specifically, each blind hole 11 contains a test tube of a size that is adapted to its dimensions and is used to hold snow or ice samples.
[0031] Specifically, the transparent stage 9 is made of epoxy resin or acrylic, and the outer circumference of the transparent stage 9 is engraved with scale lines 10 to facilitate reading the liquid level in the blind hole 11.
[0032] Specifically, the vacuum pump 4 is connected to the low-temperature test chamber 1 through the pump pipe 6, and the vacuum pump 4 is fixed next to the low-temperature test chamber 1 by the bracket 5.
[0033] Specifically, the observation window 3 is detachably and sealed to the low-temperature test chamber 1 via the sealing frame 2.
[0034] Specifically, the sealing frame 2 is connected to the low-temperature test chamber 1 by bolts.
[0035] Specifically, a sealing silicone sealant is provided between the sealing frame 2 and the low-temperature test chamber 1.
[0036] It should be noted that the low temperature test chamber 1 is a refrigeration chamber with a temperature range of 0 to -35℃, which can be adjusted in increments of 0.5℃.
[0037] This embodiment also provides a method for using the rapid performance evaluation device for de-icing agents, as detailed below:
[0038] First, add snow or ice samples to three sets of test tubes that are compatible with blind holes 11, and then put them into blind holes 11 respectively. Add an equal amount of de-icing agent to each blind hole 11 of each set. Then, put the transparent stage 9 into the low temperature test chamber 1 and seal the observation window 3 to the low temperature test chamber 1 with the sealing frame 2.
[0039] Then, the temperature inside the low-temperature test chamber 1 is lowered to the temperature of the snow or ice sample collection site by the control device 7. At the same time, the shadowless lamp 8 is turned on and the vacuum pump 4 is started to draw the vacuum degree inside the low-temperature test chamber 1 to 5-10 kPa. Finally, the melting of the snow or ice sample after the addition of de-icing agent is observed by the naked eye through the observation window 3 on the transparent stage 9, and the relevant data is recorded through the scale line 10. After comparison, a suitable de-icing agent is selected to eliminate the ice and snow on the local road surface.
[0040] It should be noted that before the experiment, the transparent stage 9, test tubes and other equipment should be placed in the experimental temperature for 10 hours to reduce the influence of equipment temperature on the experiment. The performance of each de-icing agent should be evaluated by using blind holes 11 of different sizes. At least 4 tests should be conducted, that is, for the same de-icing agent with the same hole diameter, 4 measurements should be performed, and the average value of the 4 measurements should be taken as the test result.
[0041] The above description is merely a specific embodiment of this utility model, enabling those skilled in the art to understand or implement it. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this utility model.
