As the saying goes "lousy car bottom" first, at the age of sunlight, after countless frustrations of automobile chassis, the hidden danger of corrosion and damage is very big, the location of the chassis is very low now, is close to the ground, sand and gravel is often fly up, on the rugged bumpy road, automobile chassis is also likely to "bottom", even tank rupture causing serious accidents. Rainy day, snow day chassis is easy to stick mud block, get the rust of rain, snow grain, the snow melting agent that has extremely strong corrosion is full of on the road after snow, it is to cause fatal trample on chassis more, shorten the service life of your love car greatly.

Recently, a consumer bought just three days of Land Rover cars, there is a car chassis drive shaft, flange and other parts rust; Another customer found the chassis rusting the same night he bought his Land Rover... In Zhejiang province, dozens of customers have recently complained about rust on the chassis of a variety of Land Rover models.

Chassis rust prevention is highly valued in foreign countries, because it will destroy the original support of the frame, "chassis armor" is necessary for high-end cars, such as Mercedes-Benz, BMW these high-end cars factory has a relatively perfect chassis protection measures.

When the vast majority of cars in China leave the factory, the manufacturers for cost consideration, the treatment of the chassis is very simple, only a thin layer of car undercoat coating (some are PVC material), even some cars only spray local, and the antirust paint and galvanized layer of the chassis when they leave the factory, can only play the role of antirust on the chassis under ideal environment. This is the same reason that manufacturers mark a new car's 100 km fuel consumption target (cannot be reached). So it is very necessary to wear a chassis armor for your car.

What is chassis armor?

The scientific name of automobile chassis armor is "UNDERCOATING". Instead of covering the chassis with iron armor, chassis armor is a kind of special elastic gelatinous material sprayed on the chassis to completely cover the chassis and the wheel hub. The chassis protection layer formed after natural consolidation. It is non-toxic, high cover rate, high adhesion, can be sprayed on the vehicle chassis, the wheel hub, fuel tanks, automobile coaming, luggage and other exposed parts, after rapid drying to form a layer of solid elastic protective layer, can prevent slungshot and gravel, avoid moisture, acid rain, salt of vehicle chassis metal erosion, prevents the chassis rust and corrosion, protect the owner's safety. In addition, chassis armor can also play a better role in sound insulation. Therefore, chassis armor has become the most effective chassis protection measure at present.

Two, why is the car chassis easy to rust?

1. Accidental scraping of chassis sheet metal while driving on the highway

2. High-speed impact of pavement sand on chassis when driving on highway

3. Corrosion of chassis sheet metal by moisture in the air (such as wet zone and rainy season, underground parking lot)

4. Salt corrosion of plate metal on chassis when salt is sprinkled on roads in cold and alpine regions in winter to prevent skid

5. Corrosion of plate metal in chassis by salt water in coastal areas

6. Acid rain corrosion of chassis sheet metal

What is the role of chassis armor?

1. Insulate the climate

The baking of the ground in the summer, acid rain, humidity and salt in the atmosphere, and the corrosion of snow sluicing agents on the slopes in the winter all attack the underside of the car. Chassis armor can effectively prevent rust and prevent premature aging of the car, even in the warm and humid coastal climate, with salt sea breeze blowing will also be ravaged by the steel bars and bones of scars and broken all over the body.

2. Defense against the impact of sand and stone

When the car is driving on the road condition is not good, the gravel on the road surface will be splashed by vibration after constantly hitting the car chassis and wheel hub and other parts. Chassis armor can protect the original antirust paint and galvanized layer of the chassis of the car, to prevent the metal from being exposed and rusting in contact with the moisture and acid rain in the air, and to strongly resist the spread of rust and corrosion of the inner shell parts of the car.

3. Enhance driving safety

The damaged chassis may lead to the deformation of some parts of the chassis, especially the upper and lower swing arm and the left and right direction of the tie rod, which is prone to deformation. Some slight scraping will also cause slight leakage of gasoline pan or wave box oil. These deformation and leakage are not easy to be detected, but will seriously affect driving safety. After the chassis armor anti-collision and anti-rust treatment, the chassis is not damaged, and the safety is guaranteed naturally.

4. Maintain the value of the vehicle

Data show that rust usually occurs after a new car is used for about three years. Corresponding to this is the fact that the better the vehicle is maintained, the higher its value. After a period of driving, whether it is their own use or ready to change a new car, after the chassis anti-collision anti-rust treatment of the car is certainly able to always be higher value. While buying a car is not usually an investment, the difference in the value of the same car over a number of years can be significant.

5, improve the driving comfort

Because the chassis anti-collision anti-rust with elastic material sealing treatment, on the one hand, greatly increased the smoothness of sideslip driving; On the other hand, it greatly reduces the noise of vehicles and the noise on the land during the driving process. Therefore, the driving comfort is much higher than the vehicle that has not done the chassis crash prevention and rust prevention.

6. Reduce fuel consumption

In the hot summer, facing the extremely high surface temperature, the car chassis is easy to transfer heat to the interior. If the car is air-conditioned, it needs more fuel consumption to reduce the temperature of the car. If the vehicle chassis armor is installed, it can largely insulate the heat and maintain the interior temperature, thus reducing fuel consumption.

7, with the effect of sound insulation

Whether it has the effect of sound insulation is decided according to the product. Some products contain rubber particles. Rubber particles are sprayed on the chassis and the wing plate, which can reduce the noise and dryness of the chassis, thus improving the comfort of the journey of the drivers and passengers!

Fourth, our southern car friends do not need to do chassis armor?

It rains frequently in the south and coastal cities, and the salt and moisture in the air are far greater than in the north! Whether in the process of driving or parking in the garage, not can avoid the erosion of the chassis, attached to the chassis of the soil, water accumulated in the chassis, after washing the car, and the wet air, acid rain, the metal will be carried out on the vehicle chassis, such as corrosion in air, used in vehicle chassis rusty after a period of time. The chassis armor coating can well avoid the erosion of external dirt and water vapor on the chassis, providing a good protection for the chassis!

Fifth, our northern car friends do not need to do chassis armor?

There are more snow and ice in winter in the north, especially on the highway. Almost every time it snows, the relevant departments will spray the snow melting agent on the road to make it react with the snow and ice, so as to facilitate people's travel! But we should know that the ice and snow melting agent is very corrosive to car chassis, and in some places it remains until the summer rainy season!

Six, what is the difference between the new car and the old car as chassis armor?

Car chassis armor processing as early as possible, the new car is best handled, 1-1.5 years effect is also better. A new car can be sprayed with armor material without any polishing or cleaning, and the treatment is better than a car that has been driving for several years. The chassis armor enhances the protection of the engine, driveline and tire system, and can extend the service life by 2-3 years.

Seven, chassis armor products are divided into several categories and how to choose?

There are three main categories of products on the market:

1, containing asphalt components of the chassis rust glue

The earliest antirust products, the only desirable is cheap, but after the asphalt dry will produce cracking, there are a lot of cracks, hidden in the cracks of the water, will cause "battery effect", so that the car chassis rust more severe, the harm to the car will be greater. Therefore, it is best not to use asphalt components of the chassis anti-rust glue as chassis armor.

2, oily (solvent) chassis antirust adhesive

These products contain toxic substances that are harmful to humans (solvents used as diluents, such as toluene) and can damage the environment and human health. So in some European and American countries with strict requirements for environmental protection has been used by few people. In addition, the oily (solvent) product of the adhesive layer is very hard, slightly bent, the adhesive layer will crack, lack of flexibility, in the chassis sound insulation effect is poor.

3, water-soluble chassis antirust adhesive

Because its diluent is water and does not contain toxic substances, it is also known as water-soluble chassis antirust glue for environmental protection chassis antirust glue. At present, most of these products are used in European and American countries. Water-soluble chassis antirust adhesive has strong adhesion, good elastic layer and remarkable sound insulation effect. It is the first choice material for chassis armor.

Eight, the new car is still necessary to do chassis rust?

1. Best bet: In the jargon, "The bottom is the bottom." New car chassis armor is the most affordable vehicle, can provide long-term protection.

2. Best timing: the new car chassis is clean, so that the chassis armor adhesion is high, more durable protection.

3. Best protection: the impact of stones, scraping, moisture and acid rain will cause damage to the chassis. At present, only chassis armor can provide comprehensive protection.

As the weather gets warmer, the rainy season will come unexpectedly, on the chassis of the car rust treatment, it is suggested that car friends in the car just back to spray, so that the chassis without dust clean, the best effect, the most important to protect the chassis of the car!
