搅拌车在运输时，混凝土会在短时间内凝固成硬块，而且对钢材和油漆都有一定的腐蚀性，所以每次使用混凝土贮罐后，洗净粘附在混凝土贮罐及进出料口上的混凝土是每日必须行认真维护的工作。下面我们来讲讲混凝土搅拌车的罐体油漆五点保养事项吧。
During the transportation of the mixer truck, the concrete will solidify into hard blocks in a short time and have certain corrosivity to the steel and paint. Therefore, after each use of the concrete storage tank, cleaning the concrete adhered to the concrete storage tank and the inlet and outlet must be carefully maintained every day. Now let's talk about the five maintenance items for the tank paint of the concrete mixer.
1、防龟裂保养：搅拌车行驶后如表面出现裂痕，那么平时不对漆面作护理，金属漆可能产生一种非常细微的裂痕，它会不断地渗透车漆，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，也会产生龟裂。如果裂纹中有车蜡，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。
1. Anti cracking maintenance: if cracks appear on the surface of the mixer truck after driving, the paint surface is not normally treated. The metal paint may produce a very fine crack, which will continuously penetrate the car paint until it penetrates the whole color paint layer. This phenomenon is called "cracking". Sometimes cracks may occur due to the quality of heavy painting. If there is car wax in the crack, the car body will be found to have striped cracks. Regular waxing can gradually reduce the occurrence of cracking.
2、防褪色保养：小型混凝土搅拌车褪色，大气中的油烟和污染物是造成车漆变色、褪色的主要原因。褪色与氧化不同，发生褪色时，车漆会出现不均匀的色差。中、轻度的褪色可用研磨、抛光治理，严重时必须重新喷漆。
2. Anti fading maintenance: the color of small concrete mixer truck is fading, and the oil smoke and pollutants in the atmosphere are the main reasons for the color change and fading of car paint. Fading is different from oxidation. When fading occurs, uneven color difference will appear in the paint. Medium and light discoloration can be treated by grinding and polishing, and repainting is required in case of serious discoloration.
3、防蚀痕：小型搅拌车蚀痕，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。轻微的蚀痕可用研磨抛光。
3. Anti corrosion mark: the corrosion mark of small mixer truck is surface abrasion. Insects, bird droppings, tree sap, tar and asphalt may cause erosion marks. Slight corrosion marks can be solved by grinding and polishing.
4、水痕纹：搅拌车水痕纹，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。轻微水痕纹的通过打蜡抛光可，严重时需研磨或喷漆。
4. Water mark: the water mark of the mixer truck is the mark left by the evaporation of water droplets, which is circular. Cars that are oxidized and washed with detergent are easy to get water marks. Slight water marks can be cured by waxing and polishing. In severe cases, grinding or painting is required.
5、浅划痕：混凝土搅拌车浅划痕，由于摩擦及日常护理不当，小型混凝土搅拌车车漆面出现轻微的划痕，但并未露出底漆，这种划痕在阳光下比较明显。一般采用的抛光方法去除。
5. Shallow scratch: the concrete mixer has a shallow scratch. Due to improper friction and daily care, there are slight scratches on the paint surface of the small concrete mixer, but the primer is not exposed. Such scratches are obvious in the sun. Professional polishing method is generally adopted for removal.
此外还要注重全自动混凝土搅拌车罐体的清洁工作，比如：每次装料前用水冲洗进料口，使进料口在装料时保持湿润;在装料的同时向随车自带的清洗用水水箱中注满水;装料后冲洗进料口，洗净进料口附近残留的混凝土;到工地卸料后，冲洗出料槽，然后向混凝土贮罐内加清洗用水30-40L在车辆回程时保持混凝土贮罐正向慢速转动;下次装料前切记放掉混凝土贮罐内的污水。等等。
In addition, attention should be paid to the cleaning of the tank body of the automatic concrete mixer. For example, wash the feed inlet with water before each loading to keep the feed inlet moist during loading; Fill the cleaning water tank with water while loading; Wash the inlet after loading, and clean the residual concrete near the inlet; After unloading at the construction site, wash the discharge tank, and then add 30-40l of cleaning water to the concrete storage tank to keep the concrete storage tank rotating forward and slowly when the vehicle returns; Remember to discharge the sewage in the concrete storage tank before the next loading. wait.
