　　乳化瀝青電荷試驗(yàn)儀操作方法：

　　★先連接電源線及電**連線，電**連線請(qǐng)注意插頭插座缺口必須對(duì)準(zhǔn)，紅色插頭插入紅色插座，黑色插頭插入黑色插座。

　　★將乳化瀝青試樣用孔徑1.18濾篩過(guò)濾，并盛于容器中。

　　★旋松升降架的鎖緊螺母，抬起升降架，將燒杯放入底座中。

　　★將過(guò)濾的乳化試樣注入燒杯約200ml，放下升降架，使電**板插入乳化瀝青約30mm。

　　★打開(kāi)電源開(kāi)關(guān)，按動(dòng)定時(shí)按鈕，可見(jiàn)按鈕上方的發(fā)光管會(huì)發(fā)光，此時(shí)定時(shí)器進(jìn)入工作狀態(tài)，定時(shí)為3分鐘。

　　★當(dāng)發(fā)光管熄滅，表示電**板加點(diǎn)結(jié)束，可抬起升降架，仔細(xì)觀察電**板（紅色插頭是正**，黑色插頭為負(fù)**）。如果負(fù)**板上附有大量瀝青微粒，說(shuō)明瀝青微粒帶正電荷，則該乳液為陽(yáng)離子型，反之正**板上吸附有大量瀝青微粒，說(shuō)明瀝青微粒帶負(fù)電荷，則該乳液為陰離子型。

　　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.

　　★L(fēng)oosen 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.

　　乳化瀝青電荷試驗(yàn)儀儀具與材料：

　　★燒杯：200ml或300ml。

　　★電**板：2塊，銅制，每塊**板長(zhǎng)100㎜，寬10㎜，厚1㎜。

　　★直流電源：6v。

　　★秒表。

　　★濾篩：篩孔為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.

　　乳化瀝青電荷試驗(yàn)儀試驗(yàn)結(jié)束后，若要清洗電**板，可抬起升降架，擰松導(dǎo)電柱上的固定螺釘，取下電**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.
