Description

Technical Field

[0001] The present invention relates to the technical field of asphalt flash point detection, and in particular to an asphalt flash point detection device and method thereof. Background Art

[0002] The flash point of asphalt, as a key indicator for measuring the safety and thermal stability of asphalt, is of great significance for ensuring the reliability and service life of binder materials. However, traditional asphalt flash point detection devices have many shortcomings in environmental simulation, exhaust gas treatment and ease of operation. First, in terms of environmental simulation, traditional devices often cannot accurately control the air temperature and humidity conditions during the detection process, resulting in the detection results being significantly affected by environmental factors, and accuracy and reliability are difficult to guarantee. This is mainly due to the lack of advanced humidification and heating systems, as well as corresponding temperature and humidity monitoring devices. Secondly, in terms of exhaust gas treatment, traditional devices usually lack effective exhaust gas collection and treatment mechanisms, resulting in harmful gases generated during the detection process being directly discharged into the environment, which not only pollutes the atmosphere, but also threatens the health of operators. This is mainly due to the lack of efficient filtering and treatment systems, as well as corresponding exhaust gas emission control measures. Finally, in terms of ease of operation, traditional devices are often complex in design, cumbersome in operation, and difficult to maintain and replace components, resulting in low work efficiency and high costs.
