Large automatic mixer has been used for a long time, and the effective volume of water tank has been reduced. What's going on? Large automatic mixer tank scale increase, the main reason for the reduction of the effective volume of water tank, together to understand how to clean water tank scale. First of all, when the water temperature of the water tank is at high temperature, the hydrocarbon radical in the water will combine with calcium and magnesium plasma to form insoluble calcium carbonate and magnesium carbonate, commonly known as sodium hydroxide. Then, with the continuous evaporation and concentration of water, the water alkali content increases continuously and reaches saturation, which will form scale. The increase of scale will reduce the thermal conductivity of water tank and the effective volume of water tank.

水垢的处理方法有两种：

There are two ways to deal with scale

一，人工清理，这是普通直接的办法，就是将搅拌车的水箱拆下来，使用锤、铲等工具来水垢，这种方法效率比较低，而且劳动强度较大，还容易对水箱造成损伤；还可使用普通的水箱除垢剂，这种方法不需要拆掉水箱，但是这样水垢也不够彻底，异味较大、腐蚀性较强，容易造成水箱的老化，长期以往就会缩短水箱的使用寿命。

1、 Manual cleaning is a common and direct method, which is to remove the water tank of the mixer truck, and use hammer, shovel and other tools to remove the scale. This method has low efficiency, high labor intensity, and is easy to cause damage to the water tank. Ordinary water tank scale remover can also be used, which does not need to remove the water tank, but the scale removal is not thorough enough, and the odor is relatively strong Large, strong corrosive, easy to cause the aging of water tank, long-term past will shorten the service life of water tank.
        

二：专门的水箱除垢剂。这种方法是较有效，在车辆不停车的情况下就可以进行，将专用的除垢剂直接倒入水箱中，让其充分浸泡，车辆怠速运转或行驶25分钟左右，然后将水箱及系统内的除垢剂排放掉，再加水反复的冲洗，这样水垢既干净又有效。

2： Special scale removal tank. This method is more effective and can be carried out without stopping the vehicle. Pour the special scale remover directly into the water tank and let it fully soak. The vehicle will run at idle speed or drive for about 25 minutes. Then, the scale remover in the water tank and the system will be discharged, and then the water will be added for repeated flushing, so that the scale removal is both clean and effective.

大型自动搅拌车水箱的水垢虽然清理起来不算难，但是在平时使用的过程中还是要注意，水温的升高是水垢形成的主要原因，而防冻液是可以防止水温升高的，所以防冻液要选择质量好的，这样才能保证减少水垢的形成。

Although it is not difficult to clean up the scale in the water tank of large-scale automatic mixer, attention should be paid in the process of normal use. The rise of water temperature is the main reason for the formation of scale, and the antifreeze can prevent the water temperature from rising, so the antifreeze solution should be of good quality, so as to ensure the reduction of scale formation.
