If the paint surface of concrete mixer is not treated for a long time, it will cause different degrees of oxidation and damage, so the maintenance is very important. If the carbon deposition of the mixer is light, it will affect the work efficiency, and if it is heavy, it will cause damage to the vehicle. So, how should we prevent it? What kind of paint surface needs our maintenance? Let's take a look at it.

一、混凝特搅拌车漆面的保养方法

1、 Maintenance method of paint surface of concrete mixer truck

1、漆面氧化

1. Oxidation of paint surface

混凝土搅拌车在太阳紫外线的照射下，漆膜会不断向空气中蒸发油份以到达维护自身的效果，长时间就会导致漆面油分的散失。漆面的亮度、深度都大打折扣，使漆面渐渐发白，形成氧化层，缩短了车漆的寿命，肉眼就可观察到车漆发乌、发白、无光泽等现象。氧化严重的话可以经过研磨和抛光来处理。

Under the ultraviolet radiation of the sun, the paint film of concrete mixer will continuously evaporate oil into the air to maintain its own effect, which will lead to the loss of paint oil for a long time. The brightness and depth of the paint are greatly reduced, so that the paint gradually turns white and forms an oxide layer, which shortens the service life of the car paint. The phenomenon of black, white and dull paint can be observed by naked eyes. Serious oxidation can be treated by grinding and polishing. A kind of

2、交通膜

2. Communication membrane

混凝土搅拌车内行驶过程中因为摩擦而产生激烈的静电层，静电对灰尘、油污和化学粉尘吸附能力很强，时间长了会形成一层坚硬的交通膜，这种“交通膜”极易使漆面产生氧化腐蚀，这种状况可选用研磨抛光处理。

During the driving process of concrete mixer truck, intense electrostatic layer is generated due to friction. Electrostatic adsorption capacity to dust, oil and chemical dust is very strong, and a hard traffic film will be formed after a long time. This "traffic film" is very easy to cause oxidation and corrosion of the paint surface. Grinding and polishing can be selected for this situation.

3、龟裂

3. Cracking

假如平常不对漆面作护理，金属漆可能产生一种十分细微的裂缝，它会不断地浸透车漆，直穿透整个色漆层，这种现象就叫“龟裂”。有时因为重喷漆质量的问题，也会产作龟裂。假如裂纹中有车蜡，会发现车身有条纹状的龟裂现象。经常打蜡可逐渐减少龟裂的产生。

If you do not usually do not paint care, metallic paint may produce a very subtle crack, it will continue to soak the car paint, until penetrating the entire paint layer, this phenomenon is called "cracking". Sometimes because of the quality of repainting, there will be cracking. If there is car wax in the crack, the car body will be found to have striated cracking phenomenon. Regular waxing can gradually reduce cracking.   

4、褪色

4. Fading

大气中的油烟和污染物是构成车漆变色、褪色的主要原因。褪色与氧化不同，产作褪色时，车漆会呈现不均匀的色差。中、轻度的褪色可用研磨、抛光治理，严重时有必要重新喷漆。

Lampblack and pollutants in the atmosphere are the main causes of paint discoloration and fading. Discoloration and oxidation are different. When fading occurs, the paint will present uneven color difference. Moderate and mild fading can be treated by grinding and polishing, and it is necessary to repaint when it is serious.

5、蚀痕

5. Etch mark

蚀痕是面状磨蚀。昆虫、鸟粪、树汁、焦油、沥青都有可能引起的蚀痕。细微的蚀痕可用研磨抛光处理。

The erosion marks are surface abrasion. Insects, bird droppings, tree sap, tar and asphalt may cause corrosion marks. Fine etch marks can be ground and polished. A kind of

6、水痕纹

6. Water mark

水痕纹是水滴蒸发后留下的痕迹，呈环状。氧化、常用洗涤灵清洗的车容易染上水痕。细微水痕纹的经过打蜡抛光可，严重时需研磨或喷漆。

The water mark is the mark left by the evaporation of water drops, which is circular. Oxidation, commonly used detergent cleaning car easy to dye water marks. The fine water mark can be cured by waxing and polishing, and it needs grinding or painting when it is serious.   

7、浅划痕

7. Shallow scratch

因为摩擦及日常护理不当，混凝土搅拌车车漆面呈现细微的划痕，但并未显露底漆，这种划痕在阳光下比较明显。一般选用的抛光办法去除。

Due to friction and improper daily care, the paint surface of the concrete mixer truck shows slight scratches, but the primer is not exposed, which is more obvious in the sunlight. Generally choose professional polishing method to remove.

二、混凝土搅拌车预防积碳的办法

2、 Measures to prevent carbon deposition in concrete mixer

假如搅拌车积碳轻则影响工作效率，重则会对车辆构成损坏。那么，我们应该怎么预防呢？

   if the carbon deposit in the mixer is light, it will affect the work efficiency, and if it is heavy, it will cause damage to the vehicle. So, how should we prevent it? A kind of

1、不要长期怠速行驶

1. Don't idle for a long time

怠速时间长，搅拌车发动机达到正常温度所需的时间也就变长，汽油被喷到气门背面后蒸发的速度就慢，积碳也由此而生。同时经常怠速行驶，进入搅拌车发动机的空气流量也就小，这样对积碳的冲刷作用变得也很弱，会促进积碳的堆积。

The longer the idle time is, the longer it takes for the mixer engine to reach the normal temperature. After the gasoline is sprayed to the back of the valve, the evaporation speed is slow, and carbon deposition is also generated. At the same time, often idling, the air flow into the mixer engine is also small, so the scouring effect on carbon deposition becomes very weak, which will promote the accumulation of carbon.

2、留意熄火时机

2. Pay attention to the timing of flameout

对于装有涡轮增压器的搅拌车，在高速行进或是爬坡后不要立刻熄火，在怠速运转10分钟后再熄火，装有涡轮增压器的搅拌车其构成积碳的速度比一般天然吸气式的搅拌车要快数倍。建议搅拌车在日常保养都满足的条件下每2万4万时做一下进气系统的免拆清洗，也就是在搅拌车发动机不崩溃的前提下用专用设备专用办法对搅拌车的进气道、气门、油路等简单构成积碳的部位进行清积碳的操作。

The speed of a turbocharged truck equipped with a turbocharged stirrer is 10 times faster than that of a turbocharged truck running at idle speed for several minutes. It is suggested that under the condition that the daily maintenance of the mixer is met, the intake system should be cleaned every 20000 to 40000 km, that is, under the premise that the mixer engine does not collapse, special equipment and special methods are used to clean the carbon deposition in the air inlet, valve, oil way and other parts of the mixer.

3、使用清洁汽油

3. Use clean gasoline

  

汽油中的杂质是构成积碳的主要成分，所以清洁度高的汽油构成积碳的趋势就弱一些。可是要注意高标号并不等于高质量，标号只代表油的辛烷值，并不能代表质量和清洁程度。一些车主为了确保汽油的清洁度，会采用在汽油里增加汽油清洁剂的做法。这样可有效地避免在金属表面构成积碳结层，并能逐渐活化原有的积碳颗粒并渐渐去除，然后维护搅拌车发动机免受损伤。不过汽油清洁剂的增加一定要慎重，假如加入了伪劣的产品会得到相反的作用。

The impurity in gasoline is the main component of carbon deposition, so the trend of carbon deposition in gasoline with high cleanliness is weaker. However, it should be noted that high grade is not equal to high quality. The label only represents the octane number of the oil, but not the quality and cleanliness. In order to ensure the cleanliness of gasoline, some car owners will add gasoline cleaner to the gasoline. This can effectively avoid the formation of carbon deposition layer on the metal surface, and gradually activate and remove the original carbon particles, and then maintain the mixer engine from damage. However, the increase of gasoline cleaner must be cautious, if the addition of fake products will get the opposite effect. A kind of

以上介绍的就是预防搅拌车积碳的办法，希望对大家有帮助，假如现已发生了积碳现象，建议及时处理。

The above is to prevent the mixing car carbon deposition method, I hope to help you, if there has been carbon deposition phenomenon, it is recommended to deal with it in time.
