Introduction: The instrument is in accordance with the national industry standard JTJ052 "highway engineering asphalt and asphalt mixture test procedures" in the T0631 "asphalt floating drift test" requirements of the design and manufacture. It is suitable for the determination of the floatation rate of the material such as the residue, the coal tar pitch and so on. Asphalt floating drift is the sample in the provisions of the floating drift, since the temperature into a certain water tank, gradually softened to the time required to break through the water to s said. The experimental temperature of the residue is 50 ° C and the test temperature of the coal tar pitch is 32 ° C or 50 ° C. The instrument can be used as a constant temperature water bath when it is not drilled in asphalt. Technical indicators: 1, the working power: AC 220V (-5% ~ +10%), 50Hz. 2, water bath capacity: length 370 × width 300 × height 300 (mm). 3, the amount of water: 28L. 4, heating device: electric heater, power 1300W. 5, the cooling device: a new type of refrigeration compressor. 6, temperature range: 5 ℃ ~ 80 ℃. 7, temperature control accuracy: ± 0.1 ℃. 8, floating disc: wall thickness 1.4mm ± 0.1mm, quality 37.9g ± 0.2g. 9, brass: wall thickness 1.4mm ± 0.1mm, mass 9.8g ± 0.2g. 10, ambient temperature: ≤ 30 ℃. 11, relative humidity: ≤ 85%. 12, the whole power consumption: not more than 2000W. 13, Dimensions: length 750 × width 540 × high 580 (mm). 14, the instrument net weight: 30kg
