And rubber asphalt will release more flue gas particles in the production process, and due to the addition of rubber powder, H2S, SO2 and other gases with foul odor and high toxicity will also be released.

[0039] The working process of the rubber asphalt smoke development, collection and detection test device is as follows:
[0040] Firstly, 500g base asphalt and 100g waste rubber powder are added into the reaction bottle 18, and the rubber asphalt is fully stirred by the metal stirring paddle 10. Then the three-port reaction cover 15 and the silica gel gasket 17 are attached to the flange of the reaction bottle 18, and the metal stirring paddle 10 is inserted through the middle hole of the three-port reaction cover 15. Subsequently, the three-port reaction cover 15, the silica gel gasket 17 and the metal stirring paddle 10 are clamped tightly by the sealing buckle 16.

The water vapor filter box can effectively block the passage of water molecules without affecting the passage of small molecules of smoke.

Finally, the smoke enters the detector 25 and is quickly detected by the detector.
