What is the depreciation rate of cars?
The standard of automobile depreciation rate in China is 20% after the first year of new car use, and then it will increase by 10% every year, following the law of accelerated decline. Annual depreciation rate =( 1- estimated net salvage value rate) ÷ estimated service life (year) × 100% monthly depreciation rate. Vehicle depreciation expense is the financial performance of vehicle investment recovery. It is to withdraw a certain amount of funds every year to update vehicles and maintain transportation and reproduction. Vehicle depreciation expense cannot reflect the national economy's investment in transport vehicles, but vehicle capital recovery expense can effectively reflect the economic value of vehicle depreciation. The depreciation rate of motor vehicles refers to the loss rate between the current market value of used cars and the current market value of new cars of the same type. According to the definition, the depreciation rate of a vehicle is numerically equal to its tangible loss rate, and the relationship among tangible loss rate, renewal rate and depreciation rate is: renewal rate = 1- tangible loss rate = 1- depreciation rate. The higher the depreciation rate, the worse the car condition and the lower the salvage value. The depreciation rate, like the new depreciation rate, can be used to represent the value of used cars (car residual value). For example, when the new car rate of used cars is 80%, it is emphasized that used cars are still 80% new cars and their depreciation rate is 20%, which shows that the value of used cars has lost 20% compared with the same type of new cars on the market at present.
Renovation technology of automobile paint
Painting process for vehicle renovation:
1. For vehicle polishing, it is recommended to use 1500 mesh or 2000 mesh sandpaper for circular polishing, so that the original topcoat can be polished until it loses its luster. However, it should be noted that the grinding intensity of each point should be uniform, and the corner area should be polished in place; When cleaning, it is recommended to use compressed air to blow the dust first after grinding, from top to bottom and from inside to outside, paying special attention to blowing off the dust at the corners and gaps; Wipe off the dust on the surface with sticky gauze after blowing, or dry it after cleaning with pure water (cleaning with tap water is not allowed, and metal particles in the water will cause defects in the paint film);
2. Masking: Try to remove the parts that can be removed from the body surface, and cover the parts that cannot be removed, preferably with plastic film. The transition area between the parts and the body should be handled well, so that a fine transition area will appear after renovation, which is also a guarantee of good results;
3, spray preparation, the environment is very important, if the environment is not good, there are many defects after spray painting, the effect of paint gloss after repair will always be affected, so the environment must be clean, the air circulation is small, the environmental dust is less, and the compressed air and water used should be clean;
4. Primer. The color of the base paint should be the same as the original color of the car. The darker the color, the better. When spraying the primer, adjust the flow (small), pressure and sector area of the spray gun for the first time, cover it with a thin layer as the basis for the transition with the primary color and new color, increase the flow for the second time and spray it twice, and control the film thickness between 18 ~ 23 microns. Watch the corner.
5. After drying (about 5 minutes), start spraying varnish, and spraying varnish is in the opposite direction. Spray twice, with the film thickness controlled between 35-45 microns, and then cover with a thin layer; Enter the paint room to dry. What is the depreciation rate of cars?
