1. Corrosion caused by environmental factors. The area with high relative humidity will accelerate the rusting of automatic mixer, especially when the temperature is just above freezing point. In humid areas, the automatic mixer should be kept as dry as possible to avoid local rusting and rusting. If the ventilation is poor, using high temperature to dry the full-automatic mixer, it is also easy to rust and rust the body of the full-automatic mixer.

2、有害物质的侵蚀。道路上产生的盐碱、含化学物质的灰尘，都可加速全自动搅拌车生锈，特别是受到盐碱、灰尘和水汽的污染侵蚀，会使全自动搅拌车车身部分锈蚀。在沿海一带，空气中含有盐分、工业污染所形成的酸雨等有害化学物质也会加重对全自动搅拌车的腐蚀。而在北方严寒地区，为了使道路不易结冰，通常都会在道路上喷洒盐水，而全自动搅拌车开过，也会对全自动搅拌车的车体等造成锈蚀。

2. The erosion of harmful substances. The salt, alkali and dust containing chemical substances produced on the road can accelerate the rust of the full-automatic mixer, especially the corrosion caused by the pollution of salt, alkali, dust and water vapor, which will rust the body of the full-automatic mixer. In the coastal area, the air contains salt, industrial pollution caused by acid rain and other harmful chemicals will also aggravate the corrosion of automatic mixer. In the northern cold area, in order to make the road not easy to freeze, salt water is usually sprayed on the road, and the car body of the full-automatic mixer will be rusted when the full-automatic mixer is driven.

3、机械损伤后的锈蚀。全自动搅拌车受到意外或石块碰撞而划伤表面油漆保护层，也会导致锈蚀。

3. Corrosion after mechanical damage. The automatic mixer is scratched by accident or stone collision, which can also lead to corrosion.

雨天，司机经常会碰到发动机不易启动的毛病，有时即使勉强启动起来，也是有气无力的。这种毛病的可能是出自点火系统因潮湿而产生的漏电。此外，可能是一到下雨天气变凉了，而封在分电盘内的热空气就有可能凝结成水滴而造成分电盘内部的小水灾，因而丧失了正常的点火功能。

On rainy days, drivers often encounter the problem that the engine is not easy to start. Sometimes, even if they start it reluctantly, they are still powerless. This problem may be caused by the leakage of the ignition system due to moisture. In addition, it may be that when it rains and gets cooler, the hot air sealed in the distributor may condense into water droplets, causing a small flood inside the distributor, thus losing its normal ignition function.

一旦发现是因为点火系统的潮湿而造成点火不良、搅拌车发动机性能下降的话，先用干燥的纸巾或干布把分电盘内外及电线等擦干，然后用专用干燥剂喷罐将干燥剂喷在分电盘盖、电瓶接头、火花塞、高压线及点火线圈等处，等一阵后就可启动搅拌车发动机了。

Once it is found that poor ignition and poor performance of mixer engine are caused by damp ignition system, dry the inside and outside of distributor and wires with dry paper towel or dry cloth, and then spray desiccant on distributor cover, battery connector, spark plug, high voltage wire and ignition coil with special desiccant spray tank. After a while, the mixer engine can be started.
