1. Check whether the sealing strip of the self-feeding cement mixer truck has large cracks and cracks. If the sealing strip is broken, it can be repaired with adhesive. In particular, it is easy to repair large crack strips by using special adhesive for sealing strips. Of course, if the sealing strip is seriously damaged or aged, it is better to replace it with a new one.

2、司机在使用自上料水泥搅拌车洗涤剂进行清洗门窗密封胶条之后，涂覆一层高渗透性的保护剂，这样既能防止密封条老化又能极大地提高密封条的密封性。除此之外，密封条的缝隙之间很容易塞满沙尘，从而引发锈蚀。为此，应该用刷子把沙尘等干净。

2. After cleaning the door and window sealing strips with self-feeding cement mixer detergent, the driver should coat a layer of high-permeability protective agent, which can prevent the sealing strip from aging and greatly improve the sealing of the sealing strip. In addition, it is easy to fill the gaps between the sealing strips with sand and dust, thus causing corrosion. For this reason, dust should be cleaned with a brush.

3、在更换整个车身时，应在焊缝的搭接部分涂一层密封胶，胶层厚度应约为1mm，并且胶层不得有虚粘、气泡等缺陷。在整个地板下表面和前轮罩下表面应涂3mm-4mm的弹性涂层及防腐涂层。这些措施不仅可以大大增强整车的密封性和减慢车身的锈蚀速度，而且还可以大大提高乘坐舒适性。

3. When replacing the whole car body, a layer of sealant shall be applied to the overlapping part of the weld, the thickness of the adhesive layer shall be about 1mm, and the adhesive layer shall be free of defects such as virtual adhesion and bubbles. 3mm - 4mm elastic coating and anticorrosive coating shall be applied to the entire lower surface of the floor and the lower surface of the front wheel housing. These measures can not only greatly enhance the tightness of the vehicle and reduce the corrosion rate of the body, but also greatly improve the ride comfort.

4、车门与车身的密封是一个比较困难的部位，密封要求比较严，应密封的部分比较长，各密封部位的断面形状不尽相同，而且车门启闭频繁。在自上料水泥搅拌车上常设置3道,4道密封，安装前支柱及车顶侧横梁部位的四重密封的构造。这种多道密封一般都布置在前门缝里，除具有密封功能外，还有汽车隔音降噪的作用。

4. The sealing between the door and the body is a difficult part. The sealing requirements are relatively strict. The part to be sealed is relatively long. The section shape of each sealing part is different, and the door is opened and closed frequently. Three and four seals are usually set on the self-feeding cement mixer, and the four-seal structure is installed at the front pillar and the roof side beam. This multi-pass seal is generally arranged in the front door seam. In addition to the sealing function, it also has the function of sound insulation and noise reduction of cars.

5、在车窗玻璃损坏后，司机在换用玻璃时，要检查密封条有无损伤。由于车窗经过修理后往往回复不到原来的形状，因此，这时除了要保证能轻松拉动或升降车窗玻璃外，还要注意车窗玻璃四周的密封性。如果玻璃同玻璃槽口的缝隙不均，橡胶条与玻璃、玻璃槽接触不良，司机可以用手能轻易地将密封条拉脱。

5. After the window glass is damaged, the driver should check whether the sealing strip is damaged when replacing the glass. Since the window often cannot return to its original shape after repair, in addition to ensuring that the window glass can be easily pulled or lifted, attention should also be paid to the sealing around the window glass. If the gap between the glass and the glass slot is uneven, and the rubber strip has poor contact with the glass and the glass slot, the driver can easily pull the sealing strip off by hand.

6、司机在换车顶时，应先在车顶周边压合处涂一层导电密封胶，待焊好后再在流水槽内及接缝处遍涂折边胶，这不但有助于车身的密封，更可防止车身因翻边焊缝处积水而产生早期锈蚀。

6. When changing the roof, the driver should first apply a layer of conductive sealant at the press joint around the roof, and then apply a layer of hem sealant in the gutter and at the joints after welding. This will not only help to seal the body, but also prevent early corrosion of the body due to water accumulation at the flanging weld.

7、自上料水泥搅拌车天窗是大多数家用轿车的基本配置。当汽车天窗打开时，橡胶密封条轨道暴露在空气中，难免堆积粉尘，甚跑进小沙砾。长时间使用可能导致天窗因磨损而变形，并堵塞排水孔。所以定期清理轨道，为轨道涂抹润滑油十分重要。

7. The skylight of self-feeding cement mixer is the basic configuration of most family cars. When the car sunroof is opened, the rubber sealing strip track is exposed to the air, which inevitably accumulates dust and even runs into small gravel. Prolonged use may cause the sunroof to deform due to wear and block the drain hole. Therefore, it is very important to clean the track regularly and apply lubricating oil to the track.

自上料水泥搅拌车密封胶条虽是车身内的小部件，但是它能保证开关车门沉稳厚重，还能使车内避风雨、防尘、隔热、隔音，对门窗交接的边缘起到装饰的效果。当车身受到振动与扭曲时，密封条还起到缓冲、吸震、保护玻璃的作用。因此，自上料水泥搅拌车保养无小事，任何一个环节都不容忽视。

Although the sealant strip of the self-feeding cement mixer is a small part in the vehicle body, it can ensure that the door is stable and heavy when opening and closing, and can also make the interior of the vehicle weatherproof, dustproof, heat insulation, and sound insulation, and play a decorative effect on the edge of the door and window junction. When the vehicle body is subject to vibration and distortion, the sealing strip also plays the role of cushioning, shock absorption and glass protection. Therefore, there is no trivial matter in the maintenance of the self-feeding cement mixer, and any link cannot be ignored.
