1. Check whether there are large cracks or cracks on the seals of the self loading mixer. If the seal breaks, it can be repaired with glue. In particular, the use of a special adhesive on the seal can easily fill large crack areas. Of course, if the seal is seriously damaged or damaged, replace it with a new one.

2.在驾驶员使用混凝土混合清洁剂清洁门窗密封条之后，请涂一层防渗透剂，以防止密封条老化，并显着提高密封条的密封性能。另外，密封条之间的间隙容易充满灰尘和锈蚀。因此，您需要使用刷子灰尘。

2. After the driver uses the concrete mixed cleaner to clean the door and window sealing strip, please apply a layer of impermeable agent to prevent the sealing strip from aging and significantly improve the sealing performance of the sealing strip. In addition, the gap between sealing strips is easy to be filled with dust and rust. Therefore, you need to use a brush to remove dust.

3.更换整个车身时，有必要在焊缝的重叠部分涂一层密封剂。粘合剂层的厚度约为1mm，并且粘合剂层必须没有不适当的粘合，气泡和其他缺陷。地板的整个底面和前轮盖的底面应涂3毫米4毫米的弹性涂层和防腐涂层。这些措施不仅显着提高了车身的密封性能，减缓了车身的腐蚀速度，而且大大提高了乘坐舒适性。

3. When replacing the whole body, it is necessary to apply a layer of sealant on the overlapping part of the weld. The thickness of the adhesive layer is about 1mm, and the adhesive layer must be free from improper bonding, bubbles and other defects. The entire underside of the floor and the underside of the front wheel cover shall be coated with 3mm to 4mm elastic coating and anti-corrosion coating. These measures not only significantly improve the sealing performance of the body, slow down the corrosion rate of the body, but also greatly improve the ride comfort.

4.密封门和车身是一个相对困难的部分。密封要求相对严格。要密封的部分相对较长，要密封的部分的横截面形状不同，并且门经常被打开和关闭。在自上料搅拌一体车上安装三向密封和四向密封，并安装前立柱的四密封结构和顶梁的侧梁。这样的多通道密封件通常被放置在前门的间隙中，并且除了密封功能之外，它们还具有减少车辆噪音的作用。

4. Sealing the door and body is a relatively difficult part. The sealing requirements are relatively strict. The part to be sealed is relatively long, the cross-sectional shape of the part to be sealed is different, and the door is often opened and closed. Install three-way seal and four-way seal on the self feeding and mixing integrated vehicle, and install the four-way seal structure of the front column and the side beam of the top beam. Such multi-channel seals are usually placed in the gap of the front door, and in addition to the sealing function, they also reduce vehicle noise.

5.车窗玻璃损坏后，螺丝刀应在更换玻璃时检查密封条是否损坏。窗户在维修后通常不能恢复其原始形状，因此，除了能够轻松地拉动和提起玻璃窗外，还应注意玻璃窗周围的密封。如果玻璃和玻璃容器之间的间隙不均匀，则橡胶条将不容易与玻璃和玻璃容器接触，并且驾驶员可以轻松地用手拉动密封环。

5. After the window glass is damaged, the screwdriver shall check whether the sealing strip is damaged when replacing the glass. Windows usually cannot be restored to their original shape after maintenance. Therefore, in addition to being able to easily pull and lift the glass window, attention should also be paid to the sealing around the glass window. If the gap between the glass and the glass container is uneven, the rubber strip will not easily contact the glass and the glass container, and the driver can easily pull the sealing ring by hand.

6.更换车顶时，驾驶员必须先压装并在车顶周围涂上一层导电密封胶。焊接后，在流道和接头上涂卷边胶。这不仅对身体有帮助。密封件可以防止由于法兰焊缝上积水而导致的汽车过早腐蚀。

6. When replacing the roof, the driver must first press fit and apply a layer of conductive sealant around the roof. After welding, apply crimping adhesive on the flow channel and joint. It's not just good for the body. The seal can prevent premature corrosion of the vehicle caused by water on the flange weld.

7.自上料搅拌一体车的天窗是大多数家用汽车的基本配置。当您打开汽车的天窗时，橡胶密封条会暴露在空气中，这不可避免地会积聚灰尘，甚会进入小砾石中。长期使用后，天窗可能会因磨损而变形，排水孔可能会堵塞。因此，定期清洁叉车并润滑叉车非常重要。

7. The skylight of the self loading mixer is the basic configuration of most household cars. When you open the sunroof of the car, the rubber sealing strip will be exposed to the air, which will inevitably accumulate dust and even enter the small gravel. After long-term use, the sunroof may be deformed due to wear and the drain hole may be blocked. Therefore, it is very important to clean and lubricate the forklift regularly.
