Summer rain more vehicles should pay attention to dehumidification rust

Do not know if everyone understands that car air conditioning can not only regulate the temperature of the cabin, but also effectively remove the moisture inside the cabin. With this use of air conditioners, we can consciously turn on air conditioners on a regular basis to reduce cabin humidity and prevent the growth of mold in the cabin.

If the car does not use air conditioning for a long time, the automobile water tank and the condenser surface will be covered with a large amount of dust and debris, which will cause the vehicle to have high water temperature and poor air-conditioning cooling effect, which will lead to long-term operation of the air-conditioning electronic fan, easily damaged For air conditioning, it is recommended to clean the water tank condenser surface. When there are too much dust and impurities on the surfaces of air-conditioning ducts and evaporators, mildew is likely to occur, and when the weather turns warm, a large amount of bacteria will grow. At this time, the air conditioner will find that there are odors. Therefore, before using the air conditioner, in addition to cleaning the condenser surface of the water tank, the air conditioning system must be cleaned and sterilized, replacing the air conditioning filter element.

Debris

In general, the original objects in the carriage are more or less considered the problem of mold prevention before leaving the factory. Therefore, in wet climates, mildew is often caused by debris in some compartments, such as rags under the seat, biscuit boxes left in the glove box, and even dirty shoes that have not been washed in the trunk for months. Therefore, these health “black spots” should be resolutely cleared out of the carriages to prevent mildew, odor, and contamination of the cars.

The trunk is a place where people are more likely to neglect. Many people like to put some car washing tools and debris inside. Especially where the spare tire is placed, it is easier to collect filth. The accumulated water vapor can easily flow to the spare tire of the groove. Department. If you do not use it for a long time, this part of the sheet metal and tire change tools will rust and eventually spread to the entire chassis part. Therefore, it is best not to put unnecessary debris in the trunk.

Clever use of old newspapers

When not in use, desiccant can be used instead of air conditioning and dehumidification. It is better to buy a simple dehumidification box, so that the interior parts will not be affected by moisture after overnight. There are also simple ways to roll old newspapers into a bundle and place them on the front and back pads or in the trunk. It also has the effect of dehumidification.

In addition, the excessive moisture, the CD will produce a difficult reading, many car CD box is installed in the trunk. To prevent the sound from getting wet, a small dehumidifying box can also be placed in the trunk.

Sunshine disinfection

Ultraviolet radiation in natural sunlight is of course the best and free way of disinfection. Therefore, when the weather is fine, you can find a sun-dried area, open all the doors and trunk lids, and let the moisture in the car exhaust and ventilate. Then remove the car's foot mat and seat cover, wash and dry it.

Body: Anti-corrosion and rust are key

Wax anti- ACID rain

The best way to prevent car paint from being eroded by rain is to wax. The most important role of car wax is anti-corrosion and anti-rust.

Nowadays air pollution is increasingly serious, and chemical erosive substances such as sulfides, nitrogen oxides, active free radicals, and charged particles in the air are increasing in the air. When they are mixed with the water in the air, it will form acid rain that is more harmful to the paint.

When the car is moving fast, the paint moves relative to the air and the friction generates static electricity, which will absorb a lot of dust and harmful substances. Over time, the body surface will form a layer of stubborn film with a lot of contaminants that will continue to damage the paint surface. The high-quality car wax can form a dense and hard wax film on the surface of the car body to resist all kinds of encroachment from the environment.

Another important role of car wax is to reduce the adhesion of water droplets on the paint surface. The water droplets on the paint surface become hemispherical due to the tension. In the sunlight, they are like small convex lenses that make the sun gather and burn the paint surface. This is one of the main reasons for the formation of dark spots and aging of paint. Car wax can reduce the water droplets on the paint surface by 60% to 90%, and make the water droplets remaining on the paint surface even more flat and flat, reducing the damage to the body paint surface.

Summer came, the rain was much, and the sun was fierce. Ultraviolet rays and other various rays in the sunlight are also one of the important factors that make car paints age, fade or even peel off. Long-term irradiation can destroy the chemical structure of paint polymers and pigment molecules. In particular transparent lacquer, its transparent layer generally contains protection against UV radiation, but its color lacquer layer is much thinner than traditional car paint. Therefore, once the transparent layer is damaged, the paint surface will easily start to deteriorate. Anti-ultraviolet vehicle wax fully considers the characteristics of ultraviolet rays, which greatly reduces the damage to vehicle paint.

In general, excellent car wax can maintain its effect for up to 3 months, that is, even in the long summer in the south, as long as the wax is applied twice, it can protect the car against the rain and exposure throughout the summer.

Antirust by careful

There are two main causes of body corrosion:

One is the accumulation of moisture in the holes in the body. As the car travels on the road all day long, it will inevitably encounter various road conditions, such as wet roads and muddy roads. Such a rainy season is even more common today. Some may not be cleaned in a timely manner, so that sludge may easily accumulate in the voids in the lower part of the vehicle. This is where moisture can be hidden and where rust is most likely to occur.

Followed by paint and protective layer peeling off the bottom and exterior of the vehicle. Careless car owners may not pay attention to it. Because they are not repaired in time, your car will only be harmless in wet weather. Rust is born.

Performing professional rust-proof construction can certainly solve the problem. But in fact, as long as the owners carefully, combined with daily maintenance to do, the car can be completely guaranteed to avoid corrosion, timeless.

The following points need to be paid attention to in daily maintenance:

Once it is found that the paint is peeled or scratched, it should be repaired immediately;

Inspect, clean the door and drain holes at the bottom of the car body;

Use high-pressure spray gun to clean the bottom of the vehicle;

Check the humidity inside the car. The carpets and mats will retain moisture for a long time, which will eventually lead to rust on the floor panels.

Check and repair the rust-proof coating on the lower part of the vehicle regularly.

Chassis: Anti-rust armor DIY

Bad car first bad. The chassis is the closest to the ground, and is particularly affected by the road conditions. Many cars stand up when they are repaired. The bottom shell is rusted, and the wheel shells are even loosely perforated. The reason is that the corrosive nature of acid rain is the main culprit. In the current rainy season, the accumulation of accumulated acid rain is everywhere, and Guangdong is located on the coast. The original salt content in the air is relatively large, so the vehicle chassis in the Guangdong region It will suffer more severe tests than the mainland.

In order to make the car life longer, it is recommended that both the new and old cars should be chassis rust-proof, immediately under the popular chassis armor.

The chassis armor is sprayed with a layer of polymer rubber polymer of about 5 mm at the bottom of the vehicle. After solidification, it protects the chassis like armor, so it is not easy to crack or fall off. It has the advantages of preventing sand from impact, acid rain, and corrosion resistance. In addition, chassis armor can also shock absorption and improve comfort. It should be noted that a large part of car noise comes from the noise of road noise and sand hammer. The high elastic energy of chassis armor can effectively absorb and reduce these noises. At the same time, it can also reduce the noise caused by the vibration of the chassis plate and achieve noise reduction. , to improve the comfort of the vehicle when driving.

The current high-end products in the market are mainly foreign brands, while the low-end market is mainly domestic products. General good product materials are rubber and Resin , not oil, paint, asphalt, etc. The former has permanent elasticity and high wear resistance, good anti-noise properties.

According to the grade, the current market price for chassis armor varies from two to three hundred yuan to several thousand yuan. Low-priced products do not feel comfortable with product quality and construction standards, while high-priced products make people feel sad about spending money. . In fact, as long as you have the spirit of DIY, chassis armor can be completely self-destructive. The premise is that there must be a vehicle hoist or trench that can be borrowed.
The first is the chassis cleaning. Lift the body with a lifter, clean the chassis with Detergent, and wash the sand, oil and other debris to expose the original metal surface. On the market, there are some small spray cans designed specifically for DIY. They buy the liquid chassis armor material from the supply store, and after pouring into the spray can, they are shaken well and then sprayed directly onto the parts of the chassis that need to be repaired. Pay attention to cover the brake pipe, exhaust pipe, and screw-wrench with newspaper in self-construction. Also use a special cleaning agent to prevent it from being sprayed on the paintwork.

After spraying, be sure to wait until dry. It takes about 4 hours. Touch the spray at the hand and if it is found to be no sticky, it means that it has been dry and the chassis armor DIY is done.

Abrasive

Abrasive materials include ordinary abrasives and superhard abrasives, ordinary abrasives are natural corundum, emery, brown corundum, white corundum, silicon carbide and other materials, superhard materials are natural diamond, artificial diamond, crystal, Potassium Tetroxalate, PBO and so on. At present, Abrasive materials commonly used in industrial production are Synthetic Cryolite, Potassium tetroxalate and Potassium Binoxalate.

The main purpose of Abrasive is to increase the surface area of the object material.To make the required size of particles, the material into a paste, improve the surface finish of the material, in order to meet the requirements of production and application.Used for removing rust and ink stains, polishing metal parts, etc.
