Auto parts in long-term storage, due to the temperature, humidity and gas pollution, super reserves, packaging, storage and other factors, such as improper safekeeping, make parts corrosion, mildew, deformation, breakage, etc., and therefore must be kept for the storage of fittings for regular inspection, found the problem in time, the corresponding maintenance measures are taken in time, to recover the loss and prevention. If some accessories have a qualitative change such as rust or deformation, it can not be remedied, only for scrap treatment. China international automobile wheel exhibition introduces the maintenance methods of auto parts.

(1) automobile parts corrosion and mildew damage mechanism to understand the mechanism of parts corrosion and mildew, to facilitate the use of corresponding maintenance measures to avoid and reduce parts damage and corrosion. In addition to the factors of product quality and packaging, the factors of the warehouse environment mainly include the following.

Temperature: some parts are sensitive to the temperature, easy to be affected by the temperature, temperature too high or too low will cause quality changes, affect the use of the effect. Such as rubber products at high temperatures will melt deformation, strength decreased, low temperatures will become a hard and brittle loss of elasticity. Metal products surface protection layer (oil or wax) encounter high temperature will make grease melt volatilize and dry, wax encounter high temperature melting, metal surface loss of protection layer, and be oxidized by rust. Plastic products are easy to age and become brittle at low temperatures, loss of sealing, precision instruments for a long time in the high temperature or low temperature, parts deformation error.

Humidity: China international wheel show reminds you that the humidity is too high, the surface of metal parts is easy to be oxidized rust, Mercedes truck maintenance instruments, electrical parts are easy to be oxidized rust lost sensitivity.

(3) air: the air contains a lot of water vapor, oxygen, will make the metal oxidation rust, corrosive gas corrosion of the metal parts of the surface, accelerate the progress of corrosion, cause early parts to wear.

Sunlight and rain: the sun is strong, irradiation time is too long, will make the accessories surface temperature rise, easy to make the accessories deformation.Such as rubber products, plastic products aging crack, the easiest to make parts oxidation rust, aging brittle, poor insulation.

(5) dust and impurities: will aggravate the corrosion of metal parts, and make the electrical components bad insulation, affecting the precision and sensitivity of instruments and meters.

Insect pests: all kinds of moth, termites, rats, and mice will bite the insulation cable, so that the short circuit, failure.

All landowners rust and knocked wounded: parts of rust and knocked wounded often occurs during storage, with finishing work with accessories, such as a valve, steering knuckle, kingpin, piston pin, etc., when there is slight corrosion and knock against injury occurs, available mechanical polishing, gasoline or kerosene brush or with 00 # sandpaper to rust and eliminate traces, and then rub oil protection, corrosion is serious, even derusting failed to use, can only make scrap processing.

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.
