Electric forklifts are mainly divided into internal combustion electric forklifts and battery electric forklifts. The vast majority of fuel forklifts are used in seaports, ports and industrial and mining enterprise sites. The natural environment of application is relatively extreme, especially in seaports and chemical manufacturing industries, which are affected by subtropical climate, cold and humid zone, marine climate, natural environment, organic waste gas, smoke and dust. The overall effect leads to the corrosion and damage of electric forklift parts, and the corrosion is more serious; while battery forklifts are mostly used in warehouses and other indoor sites, the environmental damage is small, and the corrosion caused by environmental elements is relatively light.
Corrosion conditions inside the electric forklift, such as high temperature and sulfur content caused by automobile engines, organic waste gas from incineration such as chloride ion content, organic gas caused by batteries, liquid leakage, vibration at work, ground stress caused by impact, friction, and impact. Partial damage, etc. is also the main reason for the corrosion and damage of electric forklift parts.
The specific principle of electrochemical corrosion is that the original metal material is converted into hydroxide, which causes the parts or components to corrode, destroy or even be damaged beyond repair. The embrittlement of non-metallic materials such as paint, vulcanized rubber, and fiberglass anti-corrosion chemical fibers is mainly due to the physical, chemical and chemical reactions of the raw materials, such as cracking, dissolving, and melting, after the overall effect of the natural environment, resulting in reduced appearance and function. It can be seen that the design structure of the electric forklift itself, the raw materials used, the processing technology and the protective measures immediately affect the corrosion resistance of the electric forklift.
