Calibration of heating temperature for ring furnace: Display time, temperature curve and comparison chart of the actual measured temperature;
The smoke concentration and smoke rate of the material are automatically calculated after being set.
A rotation chart that displays the angular velocity of the mouse cage in real time;
The operating time of the ring furnace can be set arbitrarily. It has the functions of manual and automatic rapid advance and retraction of the ring furnace.
Test principle: This test standard is formulated based on the achievements obtained from the research on the methodology of quantitative preparation of material smoke in laboratories and the methodology of experimental mouse inhalation smoke poisoning tests in China, as well as the practical experience in evaluating the smoke toxicity of materials. It is one of the important criteria for determining the combustion performance grades of A2, B, and C composite (sandwich) materials.
Main features: This building material smoke toxicity test equipment is designed simply and easy to operate. The automatic adjustment mode of the test chamber is directly controlled by software, which greatly saves manpower and material resources. Among them, the mouse cage rotates flexibly on the frame without a fixed stationary point. The poisoning box is made of colorless and transparent organic glass material, with good sealing performance, which prevents the leakage of smoke
