Asphalt rotating thin film oven

Product description by the State Ministry of JT052-2000 industry standards, and with reference to the Japanese JIS standard rotary thin film oven on design and manufacturing standards, applicable to the determination of the case of semi-solid bitumen has heating and air performance under changing circumstances, the test method closer to the actual situation in the course of heating and mixing in a short time to assess the anti-aging properties of asphalt, polymer modified asphalt test is essential equipment. The main technical parameters: 1 voltage: 220V ± 10% 2. Total power: 4KW 3. turntable speed: 15r / min ± 0.2r each can be installed eight sample bottle 4. Temperature accuracy: 163 ℃ ± 0.5 ℃ 5 . Studio Size: 430 × 410 × 400mm 6. each test: 75min 7. compressor built-in double insulation gate structure that 1, the overall arrangement: a body made of a thin steel plate, the upper half is fitted with double doors studio, the lower is the electrical control and mechanical reduction gear, look painting. 2, observed: workpiece room door is a double form, the inner thickness of 30mm, the outer layer thickness of 50mm, the center is equipped with a square glass windows. There are lights in the room, you can see the indoor pools can easily state in the determination of proceeds from the outside thermometer inserted from the front of the upper. 3, Heating: heating device at the bottom of the studio, using natural air convection heating air law. Studios and uniform heating up and down behind the duct. 4, insulation and temperature control: between the studio and the tank shell insulation and duct, for the work to the outer conductor of the indoor temperature will not affect the thermostat and thermostat sensitivity, filled with fiberglass insulation inside, the walls of the duct and studio spray high silver paint. The thickness of the two temperature points, by long change-over switch 0,1 / 3,2 / 3,1, three paragraphs, changing electric wire heating power train get rough warming and temperature control. Adjustment studio installed in an upper portion of the electrical contact thermometer contact for the specified operating temperature. 5, Studio: Studio center is equipped with four asphalt can be placed sample dish containing a turntable which is driven by the motor. You can also take away the turntable, use it as an ordinary thermostat. Note 1, start the turntable, its rotation should be controlled in 15 ± 0.2 rev / min. 2, thermostatically controlled at 163 ± 0.5 ℃, temperature controller with digital display values ??oven thermometer index values ??are tiny gap, should be based on the oven thermometer values ??prevail, such as temperature controller display value does not match the value of the dial switch, adjustable rear instrument knob to "+" or "-" to make it consistent. 3, regularly check box lube deceleration. Practice 1, turn on the power, used for heating heating "I" file and set the temperature control device to the desired temperature, when the desire to reach the desired temperature, changing the heating "I" file to "1/3" or "2 / 3 "position, hang inside the oven until thermometer indicates the temperature of" 163 ± 0.5 ℃ "balance. 2, according to the test method, the sample weighed a certain amount of asphalt, into the shrink oral vial, then evenly mounted on the turntable, when the bottle containing the sample is less than 8, the bottles should also be symmetrical loaded. 3. Start the air compressor on the oven gas, when the required time, stop heating, turntable stopped, and then open the studio goalkeeper bottle removed
