Maintenance methods of auto parts:

① Chemical derusting method: dissolve the rust layer by chemical method. General process of chemical derusting: degreasing → thermochemistry → cold water washing → derusting → cold water washing → neutralization → flowing water washing → passivation → drying → oil seal rust prevention.

② Mechanical derusting method: remove the rust layer mechanically. Generally, polish it with fine iron oxide abrasive cloth soaked in engine oil or kerosene or clean it after mechanical polishing and apply anti rust grease. Derusting depends on the shortage of accessories, the performance of accessories and the derusting cost. If it is a unsalable accessory, or the original performance of accessories is damaged by derusting, or the derusting cost is too high to carry out derusting, it shall be scrapped.

③ Arrange appropriate warehouse and storage location: various accessories have different properties and different storage requirements. Different types and properties of accessories shall be placed in appropriate warehouse and storage location respectively.

④ Accessories padded: auto parts are mostly metal products, which belong to hygroscopic substances, and should be padded generally.

⑤ Strengthen the temperature and humidity control in the warehouse, and adopt natural ventilation, mechanical ventilation and moisture-proof agent.

⑥ Strictly implement the first in, first out principle of accessories, minimize the time of accessories in the warehouse and constantly update the inventory.

⑦ Establish parts maintenance system and carry out necessary maintenance for inventory parts.

⑧ Do a good job in environmental sanitation, reduce dust and impurity pollution and prevent the breeding of pests.
