The main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine.
Compared with the injection molding material interior decoration, the foam interior decoration has a flexible and comfortable feel, at the same time, it can play a cushioning energy absorption effect in the event of a vehicle collision to protect the passengers in the car. Foaming technology is widely used in interior decoration, such as dashboard, steering wheel, auxiliary dashboard, ceiling, sunshade, door interior panel, door handrail and so on. In recent years, in order to meet the requirements of lightweight, interior products have been continuously studied and made some progress in materials and technology, in which the economical foaming technology can retain the elastic and comfortable function while reducing the thickness of the foaming layer through product design and process improvement. in order to achieve the purpose of lightweight.
The structure of the window should be able to control sunlight exposure and limit the area ratio of the window wall. For buildings with larger window area, endothermic glass, heat reflection glass or shading measures should be considered, such as sunshade panels, eaves, eaves, balconies, blinds, curtains and so on. Natural air can be directly used as a source of energy when the outdoor temperature is low, so the structure of the window should be able to open or set a natural vent on it.

Car consignment company information report according to Deutsche Welle, the market is becoming more and more important to the German automobile industry. German cars such as Audi, BMW and Mercedes-Benz are very popular with motorists. It is even said that Germany can get out of the economic crisis faster mainly due to the rapid development of the car market and the good reputation of the German car MadeinGermany.

Zhaoyuan in the building to meet the design requirements of the premise, the addition of external sunshade, awning and appropriate increase in the length of the southward balcony can play a certain sunshade effect. Heat-reflecting fabric curtains coated with metal film are arranged on the inside of the window, which has a decorative effect on the front, forming a less mobile space layer about 50mm thick between the glass and the curtains. In this way, a good effect of thermal reflection and thermal insulation can be achieved, but the direct lighting is poor and should be made into a movable type. In addition, installing blinds with certain thermal reflection on the inside of the window can also obtain a certain thermal insulation effect.
As the temperature rises, the temperature inside the car continues to rise, car sunscreen has also entered the sales peak. The traditional car sunshade and heat shield is just a simple sunscreen, which is put in the front and rear windshield of the car when parking outdoors, which is a little troublesome. On the other hand, the newly listed sunshade is improved into an automatic telescopic money, which usually absorbs the bracket on one side of the windshield and pulls out the fan-shaped fold when in use, and the material of the reflective aluminum film is not afraid of exposure. The reporter tested that the temperature in the car with sunshade for outdoor parking is about 20 degrees Celsius lower than that without sunshade.
China stipulated on October 1, 2007, “the visible light transmittance of the front windshield is not allowed to be less than 70%, and the side window glass is not allowed to post mirror reflective sunshade film.” But in real life, there are often many car owners in order to save money, choose to paste a cheap high imitation film in the automobile supplies wholesale market or roadside shop, but do not realize that this kind of inferior film, not only can not work, but also because it contains formaldehyde, benzene and other harmful ingredients to release harmful substances to the car, damage to the health of passengers, less than two years will fade, but also need secondary film, secondary consumption of
As for the vehicle lifetime warranty, it will include more items, such as common loudspeaker system, dashboard system, sub-dashboard system, ceiling, sunshade panel, signage system, seat system, power system, vehicle switch system, seat belt system, lighting system, body control system, steering wheel system, airbag system and so on. These common items are covered by the whole vehicle warranty.
1. Do a good job of cold resistance and anti-freezing measures. For Fritillaria thunbergii, Yuanhu, saffron and other traditional Chinese medicine, can cover straw, sunshade net and other anti-freezing. Control the water content of Dendrobium candidum matrix, seal the greenhouse film, prevent cold air from entering the greenhouse, and multi-layer covering can be used in the greenhouse. For breeding seedlings, potted flowers and some Lunar New year Flowers and precious flowers, it is necessary to do a good job of heat preservation in the shed, and lilies and Lunar New year flowers need to strengthen heating measures, especially when low temperature comes, pay attention to watch at night and heat up continuously to prevent frost damage caused by sudden changes in temperature in the shed. For the gerbera produced in the simple greenhouse, when the low temperature freezing comes, the film needs to be added to resist the low temperature, and a layer of non-woven cloth can be added in the greenhouse to enhance the thermal insulation performance.
