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. 白色坦克的显著特征是引人注目的。事实上，由于全自动自上料搅拌车在工作时容易弄脏，所以当混凝土附着在箱体上时，及时发现并清洗，可以避免混凝土在箱体上凝固，严重时还会腐蚀油漆。因此，白色在清洁车辆外观方面起着重要的作用。

　　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. 从物理学角度看，根据光反射原理，颜色越深，光反射强度越弱，白色材料的反射性能越好，其中黑色的吸热性强，白色的吸热性弱。在炎热的夏季，浅色能有效地反射阳光，避免阳光直射导致罐体温度急剧上升，降低全自动自上料搅拌车的吸热强度，从而降低内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、白色车辆安全系数高。由于其重心高、体积大，发生安全交通事故的概率高。从远处就能看到白色，从而提高了安全系数。搅拌器上的白漆是常见的，但没有固定的颜色。在生活中，我们仍然可以看到其他颜色的搅拌车，如红色，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.

　　所以全自动自上料搅拌车总是白色的。白色反光，不吸收热量，而白色更引人注目，可以看到车身沾有混凝土。混凝土搅拌运输及其它工作必须始终保持清洁。你一眼就能看出汽车是否脏了。此外，一眼就能看到白色，当其他司机看到白色时，他们在看道路，他们会知道车来了，所以他们可以提前做好准备，减少事故的发生。

　　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.
