攪拌車(chē)在運輸時(shí)，混凝土會(huì )在短時(shí)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(jìn)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(lái)講講混凝土攪拌車(chē)的罐體油漆五點(diǎn)保養事項吧。

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：攪拌車(chē)行駛后如表面出現裂痕，那么平時(shí)不對漆面作護理，金屬漆可能產(chǎn)生一種非常細微的裂痕，它會(huì )不斷地滲透車(chē)漆，直穿透整個(gè)色漆層，這種現象就叫“龜裂”。有時(shí)因為重噴漆質(zhì)量的問(wèn)題，也會(huì )產(chǎn)生龜裂。如果裂紋中有車(chē)蠟，會(huì )發(fā)現車(chē)身有條紋狀的龜裂現象。經(jīng)常打蠟可逐漸減少龜裂的產(chǎn)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：小型混凝土攪拌車(chē)褪色，大氣中的油煙和污染物是造成車(chē)漆變色、褪色的主要原因。褪色與氧化不同，發(fā)生褪色時(shí)，車(chē)漆會(huì )出現不均勻的色差。中、輕度的褪色可用研磨、拋光治理，嚴重時(shí)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(chē)蝕痕，蝕痕是面狀磨蝕。昆蟲(chóng)、鳥(niǎo)糞、樹(shù)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(chē)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(chē)容易染上水痕。輕微水痕紋的通過(guò)打蠟拋光可，嚴重時(shí)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(chē)淺劃痕，由于摩擦及日常護理不當，小型混凝土攪拌車(chē)車(chē)漆面出現輕微的劃痕，但并未露出底漆，這種劃痕在陽(yáng)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(dòng)混凝土攪拌車(chē)罐體的清潔工作，比如：每次裝料前用水沖洗進(jìn)料口，使進(jìn)料口在裝料時(shí)保持濕潤;在裝料的同時(shí)向隨車(chē)自帶的清洗用水水箱中注滿(mǎn)水;裝料后沖洗進(jìn)料口，洗凈進(jìn)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(chē)輛回程時(shí)保持混凝土貯罐正向慢速轉動(dòng);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.
