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.
