Do you know anything about chassis armor?

Recently, many friends around me have bought new cars, because I like to study this thing, and it has gradually become popular among my friends. People ask me all kinds of questions. Do you want to get the car film? Is fuel treasure useful? How to wax? Is rust inhibitor necessary? No, I just sprayed chassis armor on my new car recently. Let's start with it.

1 What is the chassis armor used for?

Chassis armor is an elastic protective layer sprayed on the bottom of the car, generally 2-4mm thick. After rapid drying and hardening, it protects the car chassis like armor. Because the chassis includes various important components such as engine and gearbox.

Chassis armor mainly plays the role of scratch resistance, corrosion resistance and mopping resistance. (This is for automobile chassis protection), and noise reduction and heat preservation (this is for the interior environment).

Here's a brief explanation. Scratch prevention is mainly the sand and gravel on the road surface, which is sprayed on the chassis. In fact, the impact is quite big, and it is very harmful to the chassis. In addition, corrosion is also one of the fatal injuries of the chassis, especially in the rainy south, the acidic substances in the rain will be harmful to the chassis. So anti-corrosion (or anti-corrosion) is also very important.

In addition, "dragging the bottom" often occurs when passing through the speed bump. I believe many riders are familiar with it. Some speed bumps are set in rather potholes. As soon as the car passes by, it will hear a harsh sound, which is very harmful to the impact under the car. At this time, the chassis armor can also play a better protective role. As for noise reduction, the main reason is that when gravel or foreign objects hit the bottom of the car, the noise is relatively large, and the chassis armor has a certain sound insulation effect. Temperature control is because the airflow of automobile air conditioner generally goes from bottom to top, and chassis armor can provide certain heat insulation effect.

Even in urban areas, it is difficult to ensure that the road conditions will be poor when driving on the road. What kind of gravel, construction mud, potholes and speed bumps are all traps that you often encounter when driving in urban areas (everyone who has driven a car knows). Unlike the car body, the car chassis can be seen with a little scratch, which is easily overlooked by the owner and lacks proper maintenance. In fact, the condition of the chassis largely determines the performance and life of the car, so getting chassis armor can save a lot of troubles.

2 How can I not be fooled?

Let's talk about some misunderstandings of chassis armor. First of all, some people think that the chassis of a good car has been protected before leaving the factory, which is equivalent to chassis armor, and there is no need to get another layer. Let's popularize the knowledge here. Many cars have a protective film on the chassis when they leave the factory, but this is different from the chassis armor, and it is easy to be scraped off during driving.

Secondly, there is a difference between chassis armor and chassis packaging. Some repair shops use this to fool people, and some people think it is the same, so they seal the chassis, but the actual effect is different. Simply put, the difference between chassis packaging and chassis armor lies in the materials and thickness used. Chassis packaging only plays the role of chassis protection, and the problems such as sand noise and heat preservation mentioned before can only be solved by chassis armor.

Is it really necessary to waste money? I am a car lover (after all, I thought about this car for a long time before I bought it, and I don't want to spend money indiscriminately. I never listen to the sales pitch. I have to study it myself to make a reliable decision. A few days after I got the new car, I went to get the chassis armor. This is a "hard suit", which is very necessary. It is one of my three major car maintenance.

As for some people, it is a waste of money to spend thousands of dollars to get a shell under the car, which does not have much effect and increases the self-weight of the car. Then I must say, you are wrong.

First of all, I assure you that you can't feel the weight of the chassis armor when driving. The driving experience of driving mainly depends on the performance of the car, and it is completely foolish to worry that the protective layer will increase its own weight. )

Second, the chassis armor plays a role in protecting the chassis. In fact, it protects the four major systems of the car, but it can save additional maintenance costs.

4 how to buy it in buy buy?

Before I got the chassis armor, I checked it on the Internet, and the car maintenance is basically about those big brands, so I won't introduce them one by one. Here is another sentence, car maintenance must choose big-name genuine products (otherwise, if you buy fake products, you will still maintain something, and your money will be wasted). I'm going to buy it online and then find a maintenance shop (the price of 4S shop is well known, I can save a lot of money by doing it myself, so I might as well buy a better one).

What a coincidence. When I browsed the photos of the SNH48 sisters, I found that they supported the company's car maintenance. I went in for something and found the company's car maintenance price very attractive. Results I turned over many posts and websites, compared various product parameters, and consulted many heroes who played with cars. Finally, I chose Henkel Tai Sen's five-bottle suit R2000. In addition to the price, I also considered the following points:

1. The product is 100% imported: you know, it must be 100% imported, imported, imported. ...

2. The solid content is higher than that of products in the same industry: this is more important, otherwise it will be sprayed every 5 years 10.

3. Good high temperature resistance and elasticity: this can ensure that it does not dissolve at high temperature and does not crack at low temperature. I like the outdoors very much, and it is difficult to guarantee that I will encounter extreme situations.

4. Water-based resin is very environmentally friendly: environmental protection is advocated now, so the red scarf specially posted for the profession should also keep up with the "theme" ~ ~

5 how to do chassis armor?

There are nearly 700 architectural outlets in Shanghai to choose from. More coincidentally, the nearest workshop to my home happened to be the first workshop of Hu Tu, and I made an appointment soon. After arriving at the store, I showed the staff the mobile phone verification message I received after placing the order. Then they arranged a parking space for me and started working immediately. This surprised me, because generally speaking, to do maintenance, we basically have to wait in line to start work, and there are many customers in the graffiti workshop, but the arrangement is reasonable and rapid.

1. After parking, the master will lift the car.

2. Clean all the places to be painted with cleaning oil.

3. After confirming the places that need painting, the two masters removed the fender and wrapped the parts that don't need painting with paper.

Before the construction, this guy shook violently for a few minutes, saying it was because of the high solid content. Then install the nozzle and start painting on the chassis.

Paint the car.

Because there are several layers to spray, you have to wait until the last layer is dry before spraying the next layer. Basically, the whole process is quite fast, about an hour before and after. When it was finished, the master told me to look under the car, and the whole car was quite flat. After five minutes, you can remove the paper and resume installation.

6. The painting is finished!

Chassis armor is a thick black shell, indicating that it is granular and elastic.

Special note: Here, I would like to remind you that the chassis armor must choose good weather, and never choose rainy days, which will not only affect the construction speed, but also affect the final effect. Another trick is to try to choose a flat road two or three days after construction, because the paint has not solidified just after construction and it takes some time to stabilize. After that, you can get on the road smoothly and let your car accept the road challenge. Bian Xiao has something to say.

After editing this article, Bian Xiao felt a dull pain in his knee. It turned out that my car was so slow that it was abused into a broken car. Thank the original author for his article, and finally give the original author a picture. ...
