Where there is concrete, there is a concrete mixer. Because the transportation of concrete can not use ordinary trucks or other tools, the use of special mixer is an ideal way. If concrete is not mixed in, it will soon dry out. Many users want to know why there are more white mixers. White is not used because it looks good, but because of the following reasons:

　　1. 白色坦克的顯著特征是引人注目的。事實上，由于全自動自上料攪拌車在工作時容易弄臟，所以當混凝土附著在箱體上時，及時發現并清洗，可以避免混凝土在箱體上凝固，嚴重時還會腐蝕油漆。因此，白色在清潔車輛外觀方面起著重要的作用。

　　1. The distinctive features of the white tank are remarkable. In fact, because the concrete mixer is easy to get dirty when working, when the concrete is attached to the box, it can be found and cleaned in time, which can avoid the concrete from setting on the box, and even corrode the paint when it is serious. Therefore, white plays an important role in cleaning the vehicle appearance.

　　2. 從物理學角度看，根據光反射原理，顏色越深，光反射強度越弱，白色材料的反射性能越好，其中黑色的吸熱性強，白色的吸熱性弱。在炎熱的夏季，淺色能有效地反射陽光，避免陽光直射導致罐體溫度急劇上升，降低全自動自上料攪拌車的吸熱強度，從而降低內部建筑材料的固化硬度。

　　2. From the point of view of physics, according to the principle of light reflection, the darker the color is, the weaker the light reflection intensity is, and the better the reflection performance of white material is. Among them, black has strong heat absorption and white has weak heat absorption. In hot summer, light color can effectively reflect sunlight, avoid direct sunlight to cause the tank temperature to rise sharply, reduce the heat absorption strength of concrete mixer, and thus reduce the curing hardness of internal building materials.

　　3、白色車輛安全系數高。由于其重心高、體積大，發生安全交通事故的概率高。從遠處就能看到白色，從而提高了安全系數。攪拌器上的白漆是常見的，但沒有固定的顏色。在生活中，我們仍然可以看到其他顏色的攪拌車，如紅色，橙色等。

　　3. The safety factor of white vehicle is high. Because of its high center of gravity and large volume, the probability of traffic accidents is high. White can be seen from a distance, which improves the safety factor. White paint on blenders is common, but there is no fixed color. In life, we can still see other colors of the mixer, such as red, orange and so on.

　　所以全自動自上料攪拌車總是白色的。白色反光，不吸收熱量，而白色更引人注目，可以看到車身沾有混凝土。混凝土攪拌運輸及其它工作必須始終保持清潔。你一眼就能看出汽車是否臟了。此外，一眼就能看到白色，當其他司機看到白色時，他們在看道路，他們會知道車來了，所以他們可以提前做好準備，減少事故的發生。

　　So the concrete mixer is always white. White reflects light, does not absorb heat, and white is more eye-catching, you can see the body stained with concrete. Concrete mixing, transportation and other work must be kept clean at all times. You can tell at a glance whether the car is dirty. In addition, they can see white at a glance. When other drivers see white, they are looking at the road. They will know that the car is coming, so they can prepare in advance to reduce the occurrence of accidents.
