1.檢查混凝土攪拌車的密封處是否有大裂縫和裂縫。如果密封破裂，可以用粘合劑修復。特別地，通過使用特殊的粘合劑進行密封，易于填充大的裂縫區域。當然，如果密封件嚴重損壞或損壞，請更換新的密封件。
1. Check whether there are large cracks and cracks in the sealing place of concrete mixer truck. If the seal breaks, it can be repaired with adhesive. In particular, by using a special adhesive for sealing, it is easy to fill large crack areas. Of course, if the seal is seriously damaged or damaged, replace it with a new one.
2.在駕駛員使用混小型混凝土自動攪拌車清潔劑清潔門窗密封條之后，再涂一層防滲透劑以防止密封條老化，從而大大提高了密封條的密封性能。另外，密封條之間的間隙容易充滿灰塵和銹蝕。為此，應使用刷子清除灰塵。
2. After the driver cleans the sealing strips of doors and windows with the cleaning agent of small concrete mixer truck, a layer of anti permeability agent is applied to prevent the aging of the sealing strips, so as to greatly improve the sealing performance of the sealing strips. In addition, the gap between the sealing strips is easy to be filled with dust and rust. To do this, use a brush to remove dust.
3.更換整個車身時，應在焊縫的重疊部分上涂一層密封劑。粘合層的厚度應為約1mm，并且粘合層不應具有諸如不正確的粘合和氣泡的缺陷。地板的整個下表面和前輪罩的下表面應涂3mm至4mm的彈性涂層和防腐涂層。這些措施不僅大大提高了車輛的密封性能，減慢了車身的腐蝕速度，而且還大大提高了乘坐舒適性。
3. When replacing the whole body, a layer of sealant should be applied on the overlapping part of the weld. The thickness of the adhesive layer should be about 1 mm and the adhesive layer should not have defects such as incorrect adhesion and bubbles. The whole lower surface of the floor and the lower surface of the front wheel housing shall be coated with 3mm to 4mm elastic coating and anti-corrosion coating. These measures not only greatly improve the sealing performance of the vehicle, slow down the corrosion rate of the body, but also greatly improve the ride comfort.
4.門和主體的密封是一個相對困難的部分。密封要求比較嚴格。要密封的部分相對較長，每個密封部分的橫截面形狀不同，并且門經常被打開和關閉。在混凝土攪拌車上安裝三通和四通密封件，并安裝前立柱的四密封結構和頂梁的側梁。這種多通道密封件通常布置在前門間隙中。除密封功能外，還具有減少汽車噪音的作用。
4. The sealing of the door and the main body is a relatively difficult part. The sealing requirements are strict. The parts to be sealed are relatively long, the cross-section shape of each sealing part is different, and the door is often opened and closed. Three way and four-way seals are installed on the concrete mixer truck, and the four seal structure of the front column and the side beam of the top beam are installed. This multi-channel seal is usually arranged in the front door gap. In addition to the sealing function, it also has the function of reducing car noise.
5.車窗玻璃損壞后，駕駛員應在更換玻璃時檢查密封條是否損壞。由于窗戶通常在維修后無法恢復到其原始形狀，因此除了確保可以輕松拉動或提起窗戶玻璃外，還必須注意密封性窗戶玻璃周圍。如果玻璃與玻璃之間的間隙中的水箱不均勻，并且橡膠條與玻璃和玻璃水箱的接觸不良，駕駛員可以輕松地用手拉動密封環。
5. After the window glass is damaged, the driver should check whether the sealing strip is damaged when replacing the glass. As windows usually cannot be restored to their original shape after maintenance, in addition to ensuring that the window glass can be easily pulled or lifted, attention must also be paid to the sealing around the window glass. If the water tank in the gap between the glass and the glass is uneven, and the rubber strip has poor contact with the glass and the glass water tank, the driver can easily pull the sealing ring by hand.
6.更換車頂時，駕駛員應首先壓裝并在車頂周圍涂上一層導電密封膠。焊接后，將折邊膠涂在流道和接頭上。這不僅對身體有幫助。該密封件可防止由于法蘭焊縫中積水而導致的汽車過早腐蝕。
6. When replacing the roof, the driver should first press fit and apply a layer of conductive sealant around the roof. After welding, the flanging glue is applied on the runner and joint. It's not just good for the body. The seal can prevent the premature corrosion of the automobile caused by the water accumulated in the flange weld.
7.混凝土攪拌車的天窗是大多數家用汽車的基本配置。打開汽車的天窗時，橡膠密封條將暴露在空氣中，并且不可避免地會積聚灰塵，甚至會積聚成小碎石。長期使用可能會導致天窗因磨損而變形并堵塞排水孔。因此，定期清潔履帶并在履帶上涂抹潤滑劑非常重要。
7. The skylight of concrete mixer is the basic configuration of most household cars. When the car's skylight is opened, the rubber sealing strip will be exposed to the air and will inevitably accumulate dust, even small gravel. Long term use may cause the skylight to deform due to wear and block the drain hole. Therefore, it is very important to clean the track regularly and apply lubricant on the track.
