电动叉车遭腐蚀的原因?

来源:https://www.jnhgjx.net/ 日期:2021-05-04 发布人:

电动叉车可分为内燃叉车和蓄电池叉车。大部分内燃叉车应用于港口、码头和工矿场所,使用环境比较恶劣,尤其在港口和化工行业,受亚热带、湿热带、海洋性气候环境及工业废气、粉尘的综合作用,造成叉车零部件腐蚀损坏,腐蚀较严重;而蓄电池叉车大多应用于仓库等室内场所,环境变化小,环境因素引起的腐蚀相对较轻。

Electric forklift can be divided into internal combustion forklift and battery forklift. Most of the internal combustion forklifts are used in ports, docks and industrial and mining places, and the operating environment is relatively harsh, especially in the port and chemical industry. Due to the combined effects of subtropical, humid tropical, marine climate environment, industrial waste gas and dust, the forklift parts are corroded seriously; The battery forklift is mostly used in warehouse and other indoor places, the environment changes little, and the corrosion caused by environmental factors is relatively light.
电动叉车内部产生的腐蚀环境如发动机产生的高温和含硫、氯离子等的燃烧废气,蓄电池产生的酸雾、漏液,工作中振动、冲击产生的应力,摩擦、碰撞引起的局部破损等也是引起叉车零部件腐蚀损坏的主要原因。
The corrosion environment inside the electric forklift, such as the high temperature generated by the engine and the combustion exhaust gas of sulfur and chloride ions, the acid mist and liquid leakage generated by the battery, the stress generated by vibration and impact in the work, and the local damage caused by friction and collision, are also the main reasons for the corrosion damage of forklift parts.

金属腐蚀的主要机理是原金属转化成金属氧化物,造成结构件或元件生锈、损坏甚不能修复而报废。而油漆、橡胶、玻璃钢纤维等非金属材料老化,主要是受环境综合作用后,材料高分子结构发生裂解、降解、溶解等物理和化学变化,导致外观和性能下降。可见叉车本身的设计结构、应用的材料、工艺及防护措施直接决定了叉车的耐蚀能力。
The main mechanism of metal corrosion is that the original metal is transformed into metal oxide, which causes the structure or component to rust, damage or even scrap. The aging of non-metallic materials such as paint, rubber and FRP fiber is mainly due to the physical and chemical changes such as cracking, degradation and dissolution of polymer structure after the comprehensive effect of environment, resulting in the decline of appearance and performance. It can be seen that the design structure, applied materials, technology and protective measures of forklift directly determine the corrosion resistance of forklift.
