[Laser film sunshade related knowledge]

  someone has done such an experiment. In the hot summer of a southern city, the car was parked in the open air, and a thermometer was hung at Foreside windscreen places in the carriage. At 2 pm for several consecutive days, the temperature displayed by the thermometer is above 50℃, and the highest temperature displayed at one time is 65℃.

★Harm of high temperature to car itself

in hot summer, cars parked in the open air are baked into "stoves" by the hot sun ". Let's skip the tire, which is easy to cause tire burst and the engine in the front of the car is easy to cause problems and increase fuel consumption. Let alone talk about the car inside the car, if there is no some sunshade facilities, the highly toxic ultraviolet rays and sunlight directly expose the interior of the carriage, and the plastic and leather seats of the dashboard will fade and age rapidly. Once the interior decoration is damaged, the interior environment becomes unharmonious and beautiful. If it is not replaced, it will affect the driving mood, but the replacement cost is very high. High temperature is also easy to make the limited space in the car produce toxic chemical gases, mainly including benzene, formaldehyde, acetone, xylene and so on, especially new cars that have just left the factory. These harmful substances cause poisoning unconsciously, and symptoms such as headache and fatigue gradually appear.

Warm Tip: placing lighters, reading glasses and electronic products in carriages with too high temperature can easily bring potential safety hazards. Let's see which items should not be put in the car in midsummer.

Item 1: lighter(Hazard Index:★★★★★Similar items: mousse, hair gel, carbonated soda, etc.)

many drivers have the habit of smoking in the car, and they are used to putting gas lighters on the dashboard shelf. In fact, this is very dangerous. Because the gas in the disposable gas lighter will be heated and expanded, the plastic shell will explode due to heating. Once it is close to some oil and flammable substances in the car, the consequences will be unimaginable. In the view of experienced car friends, lighters, such as canned compressed gas, are easy to expand and deform or burst due to external force after being baked at high temperature. However, canned carbonated drinks, hair gel and other similar items also have such disadvantages. If they are placed in high temperature for a long time, the compressed gas inside will also expand and cause the bottle body to rupture, which is very dangerous to be placed in the car.

Item 2: reading glasses(Hazard Index:★★★★Similar items: magnifying glass)

can a pair of ordinary reading glasses placed in the car affect the safety of the vehicle? The answer is yes. In the process of getting a car, some older drivers often use reading newspapers and periodicals to kill time in the car. After using it, they are used to putting it on the dashboard storage rack, this buried security risks. Because reading glasses belong to convex lens, it is easy to gather light together. If the light is focused for a long time, the focus temperature will be too high. In addition to accelerating the aging degree of the interior decoration, the car will be severely damaged by plastic veneer, even lead to spontaneous combustion of vehicles. In addition to presbyopic glasses, magnifying glasses are also prohibited from being placed on the top of dashboard of direct sunlight, because magnifying glasses and presbyopic glasses have the same principle, and can focus light to cause the temperature of the focus to rise. This reminds us that we should carefully place such items that can focus light in midsummer.

Item 3: battery(Hazard Index:★★★Similar items: digital cameras, MP3, mobile phones, etc.)

when the temperature in the car is high, the battery will be placed in a high temperature environment for a long time, and drum bag or even explosion will occur. This requires car owners not to place mobile phone batteries and digital camera batteries on the top of the solar direct exposure dashboard in the car and the storage rack between the rear row and the glass window. For some electronic products, such as digital cameras, MP3, mobile phones, etc., these items are all made up of precise circuit boards and other parts, which are exposed to the sun for a long time. Although the possibility of explosion is very small, but it is easy to damage these electronic products.

★Cardboard sunshade

the hot summer is like a fire, and the hot ultraviolet rays in summer want to dry the earth out of the layer of oil and then quickly. Car owners should try their best to avoid the car exposure in the sun, and try their best to park the car in the garage or in a cool place, but sometimes they must park in the open air to accept the test of the scorching sun, at this time, if your car is not equipped with corresponding sunshade measures, when you enter the car after a while, you will simply enter the steamer, which is really better than "sauna. No matter for people or cars, this has great harm. Adding a sunshade to your car is undoubtedly the most direct and practical way, just like people walking in the hot sun with more umbrellas.

Cardboard sunshade, made of high-tech paperboard material, efficient light blocking, green and environmentally friendly. It can effectively block sunlight and reflect ultraviolet rays, greatly reduce the temperature in the car, and prevent the aging and fading of the car interior. In terms of thickness, it is obviously thicker than similar products in the market, which greatly improves the thermal insulation performance and durability performance, and is also more durable. Foldable design and self-attached straps do not occupy the space in the car, making storage more convenient.

    Cardboard sunshade is used in summer sunshine. Even if the interior of the carriage is always hot, it has reduced the temperature of about 20 to 30 degrees for your car, this effect is much better than not using sunshade. It can not only ensure that the temperature inside the car is a temperature acceptable to the human body when the witness enters the car, but also protect the interior of the car calmly.
