　　乳化沥青电荷试验仪是检测仪器，适用于测定各类乳化沥青微粒离子的电荷性质，即阳、阴离子的类型。

　　Emulsified asphalt charge tester is a testing instrument,which is suitable for measuring the charge properties of various types of emulsified asphalt particulate ions,that is,cation and anion types.

　　乳化沥青电荷试验仪技术参数:

　　★电源电压：直流6V

　　★大输出负载：30mA

　　★定时精度：0.1秒

　　★定时时间3min

　　★电源电压：220V<

　　★外形尺寸：300X200X300mm

　　★重量：10KG

　　★功率：200W

　　★环境温度：5～40℃

　　Technical parameters of emulsified asphalt charge tester:

　　★Power supply voltage:DC 6V

　　★Large output load:30mA

　　★Timing accuracy:0.1 seconds

　　★Timed 3min

　　★Power supply voltage:220V<

　　★Dimensions:300X200X300mm

　　★Weight:10KG

　　★Power:200W

　　★Ambient temperature:5～40℃

　　乳化沥青电荷试验仪操作方法：

　　★先连接电源线及电**连线，电**连线请注意插头插座缺口必须对准，红色插头插入红色插座，黑色插头插入黑色插座。

　　★将乳化沥青试样用孔径1.18滤筛过滤，并盛于容器中。

　　★旋松升降架的锁紧螺母，抬起升降架，将烧杯放入底座中。

　　★将过滤的乳化试样注入烧杯约200ml，放下升降架，使电**板插入乳化沥青约30mm。

　　★打开电源开关，按动定时按钮，可见按钮上方的发光管会发光，此时定时器进入工作状态，定时为3分钟。

　　★当发光管熄灭，表示电**板加点结束，可抬起升降架，仔细观察电**板（红色插头是正**，黑色插头为负**）。如果负**板上附有大量沥青微粒，说明沥青微粒带正电荷，则该乳液为阳离子型，反之正**板上吸附有大量沥青微粒，说明沥青微粒带负电荷，则该乳液为阴离子型。

　　Operation method of emulsified asphalt charge tester:

　　★First connect the power cable and the electrical cable.Please pay attention to the gaps in the plug and socket.The red plug is inserted into the red socket,and the black plug is inserted into the black socket.

　　★Filter the emulsified asphalt sample through a sieve with a pore size of 1.18 and store it in a container.

　　★Loosen the lock nut of the lifting frame,lift the lifting frame,and place the beaker in the base.

　　★Inject about 200ml of the filtered emulsified sample into the beaker,lower the lifting frame,and insert the electric board into the emulsified asphalt about 30mm.

　　★Turn on the power switch and press the timing button.It can be seen that the LED above the button will emit light.At this time,the timer enters the working state and the timing is 3 minutes.

　　★When the light-emitting tube goes out,it means that the electric**board is finished.You can raise the lifting frame and carefully observe the electric board(the red plug is positive**,the black plug is negative**).If there are a large number of asphalt particles on the negative**plate,it means that the asphalt particles are positively charged,then the emulsion is cationic,otherwise a large number of asphalt particles are adsorbed on the positive**plate,which means that the asphalt particles are negatively charged,the emulsion is anionic.type.

　　乳化沥青电荷试验仪仪具与材料：

　　★烧杯：200ml或300ml。

　　★电**板：2块，铜制，每块**板长100㎜，宽10㎜，厚1㎜。

　　★直流电源：6v。

　　★秒表。

　　★滤筛：筛孔为1.18㎜。

　　★其它：汽油、洗液等。

　　Emulsified Asphalt Charge Tester Apparatus and Materials:

　　★Beaker:200ml or 300ml.

　　★Electric**board:2 pieces,made of copper,each**board is 100㎜long,10㎜wide,1㎜thick.

　　★DC power supply:6v.

　　★Stopwatch.

　　★Sieve:The sieve opening is 1.18㎜.

　　★Others:gasoline,lotion,etc.

　　乳化沥青电荷试验仪试验结束后，若要清洗电**板，可抬起升降架，拧松导电柱上的固定螺钉，取下电**板即可。

　　After the test of the emulsified asphalt charge tester,if you want to clean the electric board,you can lift the lifting frame,loosen the fixing screw on the conductive post,and remove the electric board.
