Problems solved by technology

Moreover, the cycle of most cultural relics degradation simulation experiments is relatively long, ranging from a few weeks to a few months
In this process, the temperature inside the simulated sample reaches equilibrium with the temperature in the constant temperature and humidity chamber, which is inconsistent with the actual deterioration of cultural relics. Therefore, it is difficult to restore the deterioration process of cultural relics and cannot explain the process and results of the experiment. The deterioration mechanism of cultural relics, not to mention the precise guidance of cultural relics protection work

Embodiment 1

[0049] First prepare a sandstone core with a diameter of 25±0.1mm and a length of 52±0.1mm, and put the sandstone core into the sample chamber 3 of the sample box 1 (with an inner diameter of 25+0.2mm and a length of 50±0.1mm) Among them, the sample box 1 is installed on the water-salt solution supply box 2 through the flange 7 . Water-salt solution replenishment gravel tank 9 is filled with the quartz sand of particle size 40-80 purpose, then the portable device of multi-space environment simulation of the present invention is placed in laboratory constant temperature and humidity box 33, and the temperature T1 of constant temperature and humidity box 33 is set The temperature is set at 35°C and the relative humidity RH is 95%. All fluid pipes and control lines are led out of the constant temperature and humidity chamber 33 to connect with the liquid reservoir (not shown) and the measurement and control system 14 .

Abstract

The invention relates to a portable device for multi-space environment simulation. The portable device comprises a sample box for accommodating samples for experimental simulation; a water-salt solution supply box connected with the sample box, filled with sand and stones and capable of supplying a water-salt solution to the sample box; and a measurement and control system used for detecting and controlling the temperature in the sample box and the water-salt solution supply box and the liquid level of the water-salt solution. The sample box comprises a sample chamber for accommodating the samples, two ends of the sample chamber are open, one end of the sample chamber is in contact with the environment, and the other end of the sample chamber is communicated with the water-salt solution supply box. According to the invention, multi-space environment simulation of multi-environment control can be realized in a common environment simulation box.

Description

technical field [0001] The invention relates to the field of degradation research of simulated samples of cultural relics, in particular to a portable device for multi-space environment simulation. Background technique [0002] In recent years, cultural strength has become an important part of a country's comprehensive national strength. All countries in the world have shown unprecedented emphasis on cultural undertakings. The research on cultural heritage protection is one of the important cornerstones of cultural undertakings. It is not only the protection of cultural relics, but also the The work of excavating the connotation of cultural relics reflects the height that a country's scientific and technological level can achieve. However, due to the preciousness of cultural relics, the preliminary exploratory research must be carried out in the laboratory, and the degradation research of the simulated samples of cultural relics is an indispensable work. [0003] So far, th...
