沥青抽提仪中英文使用说明书-献县亚星公路建筑仪器厂

一、 概述
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.

二、 仪器的工作原理
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，即可自动完成启动至停止。
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.
三、 使用方法
Ⅳ How to use
1、 按JTJ052-2000规程T0701沥青混合料的取样方法，拌好的料中采取试样。按规程中的操作方法进行试样准备。
1. Take test samples from mixture by using the sampling method of T0701 bitumen mixture in JTJ052-2000. Make preparation for test samples according to the operating method in the standard.
2、 向装有试样的烧杯中注入三氯乙烯溶剂，将其浸没并记录溶剂用量浸泡三_钟搅拌后使充分溶解（也可直接在料杯中浸泡）。
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、 将浸泡后的混合料及溶剂全部倒入离心机料杯中
3. Pour immersed mixture and solvent in feeding cup of the centrifuge.
4、 称取洁净的环形滤纸，准确至0.01g，注意：滤纸不能反复使用，有破损者也不能用。
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、 将滤纸垫在离心杯口边加盖后固紧螺丝，将收集锅盖好，在分离器出口处放回收瓶。
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、 启动电源，离心杯开始旋转，由控制电路自动调整，在二十秒钟左右达到_速。沥青溶液通过排出口流入回收瓶中。停机后，从上盖孔中加入新的溶剂，数量同前，稍停3—5分钟后，重复试验。如此经过多次分离，直至流出的溶液清澈透明为止。
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、 卸下上盖取出环形滤纸及料杯中的石料，严格按“公路沥青混合料试验规程”所要求的步骤进行操作，并计算出沥青含量。
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.
