Today some parts have rust before they go out factory without derusting paint or coating antirust grease, and some parts of casting blank face, because of the light sand or processing, not net still remaining residue or scale, although the painting, but still rust under the paint, the paint falls off, so also must clear the rust, paint layer thoroughly clean, after paint again. China international auto parts show reminds you: if it is the responsibility of the manufacturer, it should be handled in time or rejected for storage.
9 electrical instrument accessories often due to vibration, damp insulation dielectric property is damaged, contact oxidation, air gap change, contact resistance increased, resulting in runaway performance. It must be dried, swabbed, and calibrated to restore its original performance.
Storage battery and battery plate are often due to poor packaging moisture or storage period is too long, so that the plate vulcanization deterioration and scrapped. Rubber products and plastic products because the storage time is too long, or by temperature impact (high or low temperature) and aging, swelling, deformation, brittle, cork paper in crack or mold and asbestos products and broken glass products, can not be maintained, can only be scrapped.
(2) China international vehicle wheel trade fair introduces the maintenance methods and measures of auto parts for you
Chemical derusting method: the chemical method to dissolve the rust layer.The general process of chemical derusting for maintenance of Benz truck: oil removal → thermochemistry → cold water washing → derusting → cold water washing → neutralization → flowing water washing → passivation → drying → oil seal for rust prevention.
(2) mechanical derusting method: with the machine to remove the rust layer, generally with oil or kerosene-soaked in fine iron oxide emery cloth polishing or with mechanical polishing after cleaning, coated with antirust grease. Dusting should see the degree of a shortage of accessories, accessories themselves performance and derusting cost to determine if it is unsalable accessories, or after derusting damaged the original performance of accessories, or derusting cost is too high is not suitable for derusting should be scrapped.
(3) arrangement of appropriate warehouse and cargo space: various accessories performance is different, the storage requirements are different, should be different types of different properties of accessories on the appropriate warehouse and cargo space.
(4) accessories pad: car accessories are mostly metal products, belong to the subject of easy moisture, generally should pad.
(5) strengthen the temperature and humidity control in the warehouse, can take natural ventilation, mechanical ventilation, and use of a moisture-proof agent.
6. Strictly implement the principle of parts first in first out, Mercedes truck maintenance to minimize the spare parts in storage time so that the inventory is constantly updated.
Establish the maintenance system of accessories, inventory accessories for necessary maintenance.
We will improve environmental hygiene, reduce pollution by dust and impurities, and prevent insect pests from breeding.
