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.

水垢的處理方法有兩種：

There are two ways to deal with scale

一，人工清理，這是普通直接的辦法，就是將攪拌車(chē)的水箱拆下來(lái)，使用錘、鏟等工具來(lái)水垢，這種方法效率比較低，而且勞動(dòng)強度較大，還容易對水箱造成損傷；還可使用普通的水箱除垢劑，這種方法不需要拆掉水箱，但是這樣水垢也不夠徹底，異味較大、腐蝕性較強，容易造成水箱的老化，長(cháng)期以往就會(huì )縮短水箱的使用壽命。

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：專(zhuān)門(mén)的水箱除垢劑。這種方法是較有效，在車(chē)輛不停車(chē)的情況下就可以進(jìn)行，將專(zhuān)用的除垢劑直接倒入水箱中，讓其充分浸泡，車(chē)輛怠速運轉或行駛25分鐘左右，然后將水箱及系統內的除垢劑排放掉，再加水反復的沖洗，這樣水垢既干凈又有效。

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.

大型自動(dòng)攪拌車(chē)水箱的水垢雖然清理起來(lái)不算難，但是在平時(shí)使用的過(guò)程中還是要注意，水溫的升高是水垢形成的主要原因，而防凍液是可以防止水溫升高的，所以防凍液要選擇質(zhì)量好的，這樣才能保證減少水垢的形成。

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.
