1.检查混凝土搅拌车的密封处是否有大裂缝和裂缝。如果密封破裂，可以用粘合剂修复。特别地，通过使用特殊的粘合剂进行密封，易于填充大的裂缝区域。当然，如果密封件严重损坏或损坏，请更换新的密封件。
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.在驾驶员使用混小型混凝土自动搅拌车清洁剂清洁门窗密封条之后，再涂一层防渗透剂以防止密封条老化，从而大大提高了密封条的密封性能。另外，密封条之间的间隙容易充满灰尘和锈蚀。为此，应使用刷子灰尘。
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.更换整个车身时，应在焊缝的重叠部分上涂一层密封剂。粘合层的厚度应为约1mm，并且粘合层不应具有诸如不正确的粘合和气泡的缺陷。地板的整个下表面和前轮罩的下表面应涂3mm4mm的弹性涂层和防腐涂层。这些措施不仅大大提高了车辆的密封性能，减慢了车身的腐蚀速度，而且还大大提高了乘坐舒适性。
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.门和主体的密封是一个相对困难的部分。密封要求比较严格。要密封的部分相对较长，每个密封部分的横截面形状不同，并且门经常被打开和关闭。在混凝土搅拌车上安装三通和四通密封件，并安装前立柱的四密封结构和顶梁的侧梁。这种多通道密封件通常布置在前门间隙中。除密封功能外，还具有减少汽车噪音的作用。
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.车窗玻璃损坏后，驾驶员应在更换玻璃时检查密封条是否损坏。由于窗户通常在维修后无法恢复到其原始形状，因此除了确保可以轻松拉动或提起窗户玻璃外，还必须注意密封性窗户玻璃周围。如果玻璃与玻璃之间的间隙中的水箱不均匀，并且橡胶条与玻璃和玻璃水箱的接触不良，驾驶员可以轻松地用手拉动密封环。
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.更换车顶时，驾驶员应压装并在车顶周围涂上一层导电密封胶。焊接后，将折边胶涂在流道和接头上。这不仅对身体有帮助。该密封件可防止由于法兰焊缝中积水而导致的汽车过早腐蚀。
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.混凝土搅拌车的天窗是大多数家用汽车的基本配置。打开汽车的天窗时，橡胶密封条将暴露在空气中，并且不可避免地会积聚灰尘，甚会积聚成小碎石。长期使用可能会导致天窗因磨损而变形并堵塞排水孔。因此，定期清洁履带并在履带上涂抹润滑剂非常重要。
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.
