However, in the car maintenance, there are often such cases that one thinks it is to maintain the car. In fact, it is self-defeating that it damages the car, and some of them even damage the paint protection layer, resulting in paint peeling and rust. After reading the following error maintenance laws, car owners can come to the seat to see if they have such inappropriate behavior.
Under the scorching sun, many car owners like to wash their cars under the hot sun. They think that after washing, the water on the car body can be dried quickly. In actual fact, under the car wash in the hot sun, the convex lens effect caused by the water droplets will cause local high-temperature phenomenon on the top layer of the paint. After a long time, the paint will lose luster. If waxing at this time, it is also likely to cause uneven body color. Therefore, car washes and waxing are best carried out under sheltered conditions. If there is no guarantee, it is best to choose to do it on a cloudy or sunny day in the morning or in the evening.
Car wash like a bath damage air conditioning met the weather temperature, dust, the body is easy to dirty, the owner of the car wash frequency also began to rise, many car owners in the car wash also like to take a bath like myself thoroughly. But here we must pay attention to, we must keep the appearance of the car air conditioner dry, if the car air conditioner is accidentally wet, it will affect its life.
Wash too hard and hurt the paint carefully Polishing and beauty Normal sunny days, generally not very dirty, can wash once in 5-8 days, if washed once in 1-2 days, then your paint life is only 50%. Car wash in time for rain and snow to prevent corrosion. The polish itself hurts the paint, the beauty chooses a regular place to do it, and the store beauty = disfigurement.
Over-tightening of bolts Permanently deformed bolts and nuts are used to fasten many fasteners on the vehicle. It must be ensured that they have enough pre-tightening force, but they cannot be tightened too tightly. If tightened too tightly, on the one hand will cause the connector to produce permanent deformation under the action of external force; on the other hand, it will cause the bolt to produce permanent deformation, even cause slipping or breaking.
The fan belt is too tight The bearing load is high When the temperature is too high, some drivers think that raising the belt tightness of the fan can improve the cooling effect of the engine. Therefore, the fan belt tightness is constantly improved, and it is not knowing that doing so is harmful. The fan belt should be kept tight and tight. Over-tightening can lead to excessive bearing load and increase power consumption. At the same time, the shaft of the water pump can be bent. The belt is stretched and deformed, and its service life is shortened.
Imported tires do not apply Some people like to buy tires particularly like to emphasize "import." New foreign tires are not very suitable for domestic users. Europe's road surface is quite different from the domestic ones. Tires that are suitable for European road conditions are difficult to perform well at home. It is just like wearing a brand-name Italian leather shoes to walk a stone road, and it is inevitable that the tyres will be packaged from the side. After the tires of some foreign brands are jointly produced in China, they have added a layer of cord fabrics on the side of the tire according to the domestic road conditions, which greatly enhances the impact resistance of the sidewalls. The tires produced by the joint venture can completely replace imported goods in terms of performance. .
The water flow of the car wash is also tricky. From the appearance, the car wash is just a simple manual labor. It seems that there is no skill, but the water flow of the car wash is very particular. A professional car wash shop will never use a high pressure water gun to spray it. Usually, the first time must be slow, flowing down from the top to the bottom, and the dust particles on the car should be taken away with water. If you use a high-pressure water gun at the beginning, it is equal to making the dust particles "frictional motion" on the paint surface.
Sometimes, car owners often wash cars in roadside shops to save time, and those who wash buckets to wash cars, if you look closely, you will find that there is a lot of silt in their buckets, no difference with sandpaper. Some towels used by the car wash shop were also eliminated from the hotel. The towels looked very new and white, but they were actually very rough, and they also hurt the car.
The waxing effect of the circle method is poor Many people wax the body habitually in a circle, which is incorrect. The correct method of waxing is straight line, horizontal and vertical lines alternately, and then press the last one in the direction of rainwater flow, so as to achieve the effect of reducing concentric circular halo on the paint surface.
Washing car washing the most wounded car paint saw the staff washing very seriously, washing bubbles flying all over the sky, so many owners will think that the dirty car will be sent to the car wash as long as all "OK", washed out from the outside looks very clean. If you want to know what the car wash shop is for you when you wash your car, you can use your fingers to pinch and sniff the bubbles and you will find that it is a washing powder! The detergent is an alkaline detergent that damages the paint. Very large, if you use the detergent for a long time to wash the car, the car's surface will gradually lose its luster. When the owner found out that his car had been washed out, it was too late.
