攪拌車在運輸時，混凝土會在短時間內凝固成硬塊，而且對鋼材和油漆都有一定的腐蝕性，所以每次使用混凝土貯罐后，洗凈粘附在混凝土貯罐及進出料口上的混凝土是每日必須行認真維護的工作。下面我們來講講混凝土攪拌車的罐體油漆五點保養(yǎng)事項吧。

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、防龜裂保養(yǎng)：攪拌車行駛后如表面出現(xiàn)裂痕，那么平時不對漆面作護理，金屬漆可能產生一種非常細微的裂痕，它會不斷地滲透車漆，直穿透整個色漆層，這種現(xiàn)象就叫“龜裂”。有時因為重噴漆質量的問題，也會產生龜裂。如果裂紋中有車蠟，會發(fā)現(xiàn)車身有條紋狀的龜裂現(xiàn)象。經常打蠟可逐漸減少龜裂的產生。

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、防褪色保養(yǎng)：小型混凝土攪拌車褪色，大氣中的油煙和污染物是造成車漆變色、褪色的主要原因。褪色與氧化不同，發(fā)生褪色時，車漆會出現(xiàn)不均勻的色差。中、輕度的褪色可用研磨、拋光治理，嚴重時必須重新噴漆。

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、防蝕痕：小型攪拌車蝕痕，蝕痕是面狀磨蝕。昆蟲、鳥糞、樹汁、焦油、瀝青都有可能引起的蝕痕。輕微的蝕痕可用研磨拋光。

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、水痕紋：攪拌車水痕紋，水痕紋是水滴蒸發(fā)后留下的痕跡，呈環(huán)狀。氧化、常用洗滌靈清洗的車容易染上水痕。輕微水痕紋的通過打蠟拋光可，嚴重時需研磨或噴漆。

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、淺劃痕：混凝土攪拌車淺劃痕，由于摩擦及日常護理不當，小型混凝土攪拌車車漆面出現(xiàn)輕微的劃痕，但并未露出底漆，這種劃痕在陽光下比較明顯。一般采用的拋光方法去除。

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.

此外還要注重全自動混凝土攪拌車罐體的清潔工作，比如：每次裝料前用水沖洗進料口，使進料口在裝料時保持濕潤;在裝料的同時向隨車自帶的清洗用水水箱中注滿水;裝料后沖洗進料口，洗凈進料口附近殘留的混凝土;到工地卸料后，沖洗出料槽，然后向混凝土貯罐內加清洗用水30-40L在車輛回程時保持混凝土貯罐正向慢速轉動;下次裝料前切記放掉混凝土貯罐內的污水。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.
