Description

Electronic moisture-proof box for asphalt SBS content tester

Technical Field

The utility model belongs to the technical field of the dampproofing case technique and specifically relates to indicate an electronic dampproofing case for pitch SBS content measurement appearance.

Background

The excellent road performance of the SBS modified asphalt is widely accepted and is widely applied to the construction and maintenance of projects such as high-grade highways, airport roads, bridge deck pavement and the like. The SBS modified asphalt is a blend of matrix asphalt and a modifier SBS, and the SBS content is one of important factors determining the pavement performance of the SBS modified asphalt. The content of the SBS modifier in the modified asphalt is determined by utilizing the infrared spectrum characteristics of the substrate asphalt and the SBS and the direct proportional relation between the infrared absorption intensity of the characteristic functional group of the substance to be detected at a specific wave number and the concentration of the substance according to the Lambert-Beer law.

The asphalt SBS content tester is based on a Fourier infrared spectroscopy measuring instrument, is a device for accurate detection and analysis, and can perform accurate testing and testing functions in the using process. While reliable infrared spectrometers allow the user to quickly obtain the primary information element of a substance being tested, there is still a need to operate to specification and take care of the environmental conditions used during use. Under the following environmental conditions, the use of the equipment is not suitable, otherwise the equipment can be damaged.

Firstly, the method comprises the following steps: too humid environment

It is also very sensitive to humid environments due to its high accuracy. Therefore, it is not necessary to use the device in an environment that is too humid during use, in order to avoid errors or inaccuracies in the detection of the device and possibly to leave the device in a humid environment for a long time. An abnormality or a damage.

Secondly, the method comprises the following steps: environment with too high temperature

Infrared spectrometers are also not suitable for use in many high humidity environments because many materials cannot be identified and tested under the influence of high humidity, and the resulting test data and identification of material properties is greatly affected.

Thirdly, the method comprises the following steps: high magnetic field environment

For many high magnetic field environments, the accuracy of infrared spectrometers can be severely affected. Thus, avoiding the use of equipment in certain high magnetic field environments can affect the accuracy and interference of the magnetic forces, and there are a number of magnetic field environments. Magnetic forces can disrupt the normal detection of raman spectrometers, such as factory workshops and computers or televisions with certain magnetic fields, and it is preferable not to use high precision raman spectrometers in these locations.

Optical element in infrared spectrum instrument. For example, a conventional KBr beam splitter is easy to damp and deform; if the optical lens in the photometric path is under the condition of large temperature change, the optical path difference is easy to change, and the optical lens and the optical path difference easily have relatively large influence on the precision of the instrument. Many times, the sampling of solid samples requires the use of KBr powder, a plate that is prone to moisture agglomeration, and therefore requires the laboratory to maintain a low relative humidity, preferably stable.

In order to ensure the normal work and durability of the instrument, the humidity of the use environment of the instrument is recommended to be kept below 60% RH. And the humidity of the southern climate in China is over 70% in most of time, even the humidity can reach over 90% in spring when rainwater is too much, and the storage and the use of the spectrum high-precision instrument are influenced greatly.

Therefore, there is a need to develop a solution to the above problems.
