Ⅰ Introduction
本儀器根據交通部2000年公路工程瀝青及瀝青混合料試驗規程JTJ052-2000中T0722-1993的技術規范要求,經改進設計的離心分離法試驗儀器。用離心法抽提測定粘稠石油瀝青拌制的瀝青混合料中的瀝青含量(或石油比)。適用于新拌瀝青混合料,也適用于舊路采取的混合料試樣。該儀器操作方便、使用壽命長,是目前很理想的試驗設備。
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
電壓:220V—50Hz 功率:550W
轉速:≥3000轉/分 容積:>3000克
Voltage: 220V—50Hz Power: 550W
Rotating speed: ≥3000rpm Capacity: >3000g
Ⅲ Working principle
儀器采用進口變頻器自動控制主機從低速到高速及快速停機。配置時間定時器,只需開啟一個開關,即可自動完成啟動停止。
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.
