The most obvious feature of the white can body is eye-catching. In fact, because the concrete mixer truck is easy to get dirty during work, it can be found and cleaned in time when the car body is stained with concrete, so as to avoid the corrosion of paint when the concrete solidifies on the car body. Therefore, white plays an important role in cleaning the appearance of the whole vehicle.

从物理学角度，根据光线反射的原理，颜色越深，光线反射强度越弱，白色的物质反光性比较好，其中黑色吸热强，白色弱。在炎热的夏季采用浅色的外形颜色，能够有效地反射太阳光，避免阳光直射造成的罐体温度急剧上升，可降低混凝土搅拌车吸热强度，从而减少内部建筑材料搅拌物凝固的硬度。

From the perspective of physics, according to the principle of light reflection, the darker the color, the weaker the light reflection intensity, and the reflective property of white materials is better, among which black has the strongest heat absorption and white is the weakest. In the hot summer, the light shape color can effectively reflect the sunlight and avoid the sharp rise of tank temperature caused by direct sunlight, which can reduce the heat absorption intensity of concrete mixer truck and reduce the solidification hardness of internal building materials.

白色的车辆系数高。

White vehicles have a high safety factor.

混凝土搅拌车本身由于偏高，体型过大，交通事故发生概率就高。白色能让人远远就注意到，从而提高了系数。

Due to the high center of gravity and large size of the concrete mixer, the probability of safety traffic accidents is high. White can be noticed from a distance, which improves the safety factor.

当然，混凝土搅拌车系数提高，除了使用白色的涂装之外，通过对车队、车辆的管理也能提高系数。

Of course, the safety factor of concrete mixer truck can be improved. In addition to using white coating, the safety factor can also be improved through the management of fleet and vehicles.

就比如说开工快线在砼车管理上，打造率的车辆调度中心与车队管理。通过GPS位置查询，便可随时监控砼车的运作情况，对超速、绕行、非工地卸料、司机偷油、偷料等异常情况进行报警记录，方便了调度及时纠错，保证正常的运输。

For example, in terms of concrete vehicle management, the construction express line will create an efficient vehicle dispatching center and fleet management. Through the GPS position query, the operation of the concrete truck can be monitored at any time, and the abnormal conditions such as overspeed, detour, off-site unloading, driver oil stealing and material stealing can be alarmed and recorded, which facilitates the dispatching to correct errors in time and ensure normal transportation.

司机通过电子送货单，自动导航到达工地，在一定程度上减少了兜路、走错路的几率，司机既可以“多跑几趟”、“早点跑完”，又能保证驾驶。另外，刷卡排队进站，加上LED大屏幕的指引司机装料，让司机看屏装料、同时在休息室休息，劳逸结合，减少因疲劳引起的交通事故。

The driver arrives at the construction site through electronic delivery note and automatic navigation, which reduces the probability of taking the wrong road to a certain extent. The driver can not only "run more times" and "finish running early", but also ensure driving safety. In addition, the card swiping queue and the LED large screen guide the driver to load, so that the driver can watch the screen to load and rest in the lounge at the same time, combining work and rest, so as to reduce traffic accidents caused by fatigue.

事实上，自动搅拌车白色涂装只是常见，但是并没有固定的颜色。在生活中，我们还是可以看到其他颜色的搅拌车，例如说红色、橙色等等。

In fact, the white coating of automatic mixer truck is only common, but there is no fixed color. In life, we can still see mixing cars of other colors, such as red, orange and so on.
