When the temperature decreases in winter, choose the plastic film with good transparency and strong insulation to cover the windows, doors and ceilings. When the outdoor temperature drops below zero, the windows and doors are covered with a layer of plastic film, and the ground is padded with rice chaff, rice straw or heat sources in the shed. However, attention should be paid to ventilation to prevent the occurrence of diseases. With the increase or decrease of temperature in spring and autumn, the plastic film should be opened or covered appropriately in time. Mainly do a good job of cooling in summer. When it is too hot, open all the windows and vents, turn on the electric fan to cool down when possible, and hang the sunshade net where the sun shines.

The upstream of automobile interior includes alloy and plastic, leather, fabric, etc., and in the middle reaches, there are all kinds of interior products, such as seats, dashboards, door panels, steering wheels, ceilings, sunshades, posts, coat racks, storage boxes, acoustics and other systems. it is an important parts system that is in close contact with passengers, which should meet the requirements of functionality, comfort, economy, durability and so on.

The main function of the car sunshade is to reduce the temperature in the car and prevent the sun from reaching the objects in the car directly. Sunscreen is a combination of multi-layer bubble film and aluminum foil, which belongs to a kind of plastic products. Bubble film has good strength, toughness and impact resistance. Aluminum foil has the ability to reflect light, thus reducing thermal radiation and has low thermal radiation conductivity. When the sun shines on the sunshade, some of the heat will be blocked, and the ultraviolet light will be reflected by the aluminum foil. If you park for a short time, you can use a simple sunshade in the front windshield of the car, which is more durable and practical. The effect of shading is better.

At first, the improved locomotive did not have any front windows. After the EF58 electric locomotive was put into operation, the locomotive was modified according to the climatic environment along the line, such as installing an icicle cutting plate above the front window glass to prevent the running locomotive from hitting the icicles falling at the entrance of the tunnel and causing damage to the window. and add a cover to the whistle. In the later period, when the locomotive was transferred to the warmer climate area, the whistle cover of the locomotive was removed, but some locomotives only removed the icicle cutting plate and retained the whistle cover during car body maintenance. In addition, some EF58 electric locomotives in Hiroshima area are also equipped with front window windows, but the purpose is completely different from that of crossing the line, but it is used as a sunshade.

As the car audio is often installed in the upper part of the dashboard, in order to prevent the reflection of the sun, the effect of the sunshade is better. If the door and window sealing strip is not strict, it should be changed, otherwise the loudspeaker is easy to rust and damage, so as to form a short circuit and burn the host. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so the level affected by the temperature change is not the same. In the scorching sun, it is best to use the sunscreen to resist the scorching sun and prevent the direct sunlight.
