1704次Ⅰ Introduction
本仪器根据交通部2000年公路工程沥青及沥青混合料试验规程JTJ052-2000中T0722-1993的技术规范要求,经改进设计的离心分离法试验仪器。用离心法抽提测定粘稠石油沥青拌制的沥青混合料中的沥青含量(或石油比)。适用于新拌沥青混合料,也适用于旧路采取的混合料试样。该仪器操作方便、使用寿命长,是目前很理想的试验设备。
This device is centrifugation separation test device designed and improved according to the requirements of T0722-1993 technical specification in JTJ052-2000 Standard test methods of bitumen and bituminous mixtures for highway engineering issued by the Ministry of Construction in 2000. It extracts and determines bitumen content (or petroleum ratio) in bitumen mixture mixed by viscous petroleum bitumen. It is applicable for newly-mixed bitumen mixture and also applicable for test sample of mixture adopted for old rods. This device is easy to operate with long service life, so it is ideal test equipment.
Ⅱ Main technical parameters
电压:220V—50Hz 功率:550W
转速:≥3000转/分 容积:>3000克
Voltage: 220V—50Hz Power: 550W
Rotating speed: ≥3000rpm Capacity: >3000g
Ⅲ Working principle
仪器采用进口变频器自动控制主机从低速到高速及快速停机。配置时间定时器,只需开启一个开关,即可自动完成启动停止。
The device employs imported transducer to automatically control the main frame to change from low speed to high speed and stop rapidly. It is provided with a timer. Only by turning on a switch, it can automatically complete start to stop.
Ⅳ How to use
1. Take test samples from mixture by using the samp method of T0701 bitumen mixture in JTJ052-2000. Make preparation for test samples according to the operating method in the standard.
2. Inject trichloroethylene solvent in the beaker with test samples, immerse them and record amount of solvent used. Immerse them for 30 minutes and mix them so that they sufficiently dissolved (You can also directly immerse them in feeding cup)
3. Pour immersed mixture and solvent in feeding cup of the centrifuge.
4. Weigh clean circular filter paper accurate to 0.01g. Attention: the filter paper can’t be used repeatedly. The broken one can’t be used.
5. Fill the filter paper around the opening of the centrifugal cup, cover it and fasten screws. Cover the collecting pot and place the recovery bottle at the outlet of the separator.
6. Turn power on and the centrifugal cup starts to turn. Automatically regulated by control circuit, it will reach the maximum speed in about 20 seconds. The bitumen solution flows in the recovery bottom via the discharge port. After stopping, add same amount of new solvent from the upper cover hole and wait for 3-5 minutes and repeat the test. It undergoes many times of separation until the solution flowed out becomes clear and transparent.
7. Disassemble the upper cover and take out the circular filter paper and stones in the feeding cup. Operate strictly according to the steps required in the Standard test methods of bitumen and bituminous mixtures for highway engineering and calculate the bitumen content.
Ⅴ Attentions
1. A place where it is flat, stable and ventilated shall be selected for instal this device.
2. Keep the device clean and solution is forbidden to enter the motor to avoid damaging it.
3. In case of abnormal sound or other troubles, cut off power to examine.
4. After the test is over, clean it to avoid causing troubles.
