瀝青離心式分離機

　　騰達試驗儀器廠：

　　瀝青離心式分離機適用于熱拌熱鋪瀝青混合料路面施工時的瀝青用量檢測，以評定拌和廠產品質量。此法也適用于舊路調查時檢測瀝青混合料的瀝青用量，用此法抽提的瀝青溶液可用于回收瀝青，以評定瀝青的老化性質。

　　Asphalt centrifugal extractor is suitable for testing the amount of asphalt used in the construction of hot-mixed hot-paved asphalt mixture pavement to evaluate the quality of the product of the mixing plant.This method is also suitable for detecting the amount of bitumen in asphalt mixtures when surveying old roads.The bitumen solution extracted by this method can be used to recover bitumen to evaluate the aging properties of bitumen.

　　瀝青離心式分離機操作規程：

　　★向裝有試樣的燒杯中注入三氯乙烯溶劑，將其浸沒，記錄熔劑用量，浸泡30min，用玻璃棒適當攪動混合料，使瀝青充分溶解。注：也可直接在離心分離器中浸泡

　　★將混合料及溶液倒入離心分離器，用少量溶劑將燒杯及玻璃棒上的粘附物全部洗入分離器中。

　　★稱取潔凈的圓環形濾紙質量準確至0.01g。注意，濾紙不宜多次反復使用，有破損者不

　　★將濾紙墊在分離器邊緣上，加蓋緊固，在分離器出口處放上回收瓶，上口應注意密封，防止流出溶液成霧狀上散失。

　　★接通電源，打開開關，三位數碼顯示000表示機器正常。按啟動鍵，分離機開始工作，工作過程為低速20秒（這時從機器中部看到點擊轉動，如不轉，可微調后面板低速調節，使之慢慢轉動）中速20秒，（同低速相同，調節中速使之轉速高于140秒，合計180后自動停機。

　　★從上蓋得孔中加入新的熔劑，稍后3-5min后，按復零鍵再按啟動鍵，分離機重新自動完成，如此操作數次直到流出的抽提液成清澈淡黃色為止。注意：每次加入三氯乙烯溶劑不得超過浸泡容量，一般200毫升左右。

　　★卸下上蓋，取圓形環濾紙，在通風櫥或室內空氣中蒸發干燥后，然后放入105±5℃烘箱中干燥，稱取質量，其增重部分為礦粉的一部分。

　　★將容器中的集料仔仔細取出，在通風櫥或空氣中蒸發后放入105±5℃烘干（一般需要4h），然后放入干燥中冷卻至溫室，稱取集料。

　　Asphalt centrifugal extractor operating procedures:

　　★Inject the trichloroethylene solvent into the beaker containing the sample,immerse it,record the amount of flux,soak it for 30 minutes,ａnd stir the mixture with a glass rod to fully dissolve the asphalt.Note:You can also soak directly in the centrifuge

　　★Pour the mixture and solution into the centrifugal separator,ａnd wash all the adherends on the beaker and glass rod into the separator with a small amount of solvent.

　　★Weigh the clean round filter paper to an accuracy of 0.01g.Note that filter paper should not be used repeatedly.

　　★Place the filter paper on the edge of the separator,cover it tightly,ａnd put a recovery bottle at the separator outlet.The upper mouth should be sealed to prevent the outflowing solution from becoming misty and lost.

　　★Turn on the power and turn on the switch.The three-digit digital display 000 indicates that the machine is normal.Press the start button,the separator starts to work,the working process is 20 seconds at low speed(at this time,click and rotate from the middle of the machine,if you do not turn,you can fine-tune the rear panel low speed adjustment to make it rotate slowly)at 20 seconds,Low speed is the same,adjust the medium speed to make the speed higher than 140 seconds,ａnd stop automatically after a total of 180.

　　★Add new flux from the hole in the upper cover.After 3-5min later,press the reset button and then the start button.The separator will automatically complete again.Do this several times until the extracted liquid becomes clear yellow.Note:Each time you add trichloroethylene solvent,it should not exceed the soaking capacity,usually about 200 ml.

　　★Remove the upper cover,take the circular ring filter paper,evaporate and dry it in a fume hood or indoor air,then dry it in an oven of 105±5℃,weigh it,ａnd the weight increase part is part of the mineral powder.

　　★Take out the aggregates in the container carefully,evaporate them in a fume hood or air,ａnd put them in 105±5℃to dry(usually 4h),then put them in the cooler to the greenhouse,ａnd weigh the aggregates.
