Car shipping companies always pay attention to the sound affected by high temperature and humidity. Now most cars are equipped with CD equipment. 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.
The 13th Guangzhou sunshade door and window Exhibition, sponsored by Guangzhou Slogart Exhibition Planning Co., Ltd., will be solemnly opened in Guangzhou International Purchasing Center from July 8 to 10, 2023. With the theme of “Intelligent Technology, Green Building, Energy Saving and Environmental Protection”, this exhibition strives to create a building materials industry exhibition platform for domestic customers and traders. As a weather vane of the industry, this platform provides a high-quality procurement platform for dealers, real estate developers, engineers, and even designers, decoration and decoration market, building materials market, door and window market, building materials supermarket, etc., and also provides enterprises with a good opportunity to show new products, expand the market, build channels and promote brands.
In terms of temperature management, the early growth stage of spring cauliflower cultivation was in the low temperature season, and the growth was small, while the plant size of broccoli was closely related to the flower head yield, and the temperature increased rapidly in the later growth stage, which was disadvantageous to the flower bud differentiation and flower ball formation of broccoli. Therefore, in the field management, it is required to do a good job of heat preservation in the early stage of growth to prevent freezing. Those cultivated in greenhouse should be closed in time to keep warm, those cultivated in open field should be trenched and drained as soon as possible to prevent freezing, and the remedial method of covering the floating surface of sunshade net should be adopted in case of sudden frost or freezing weather. In the later stage of growth, after the temperature rises in April, the protected cultivation should do a good job of ventilation and cooling in time, and the flower heads should be harvested in time after maturity.
Under the scorching sun, the temperature inside the car will rise sharply to 50-60 ℃ or higher, so the damage to the dashboard and leather seats can be imagined. Therefore, for cars exposed to the sun, sunshades are a good choice, which can reflect sunlight, avoid exposure and have a certain effect on thermal insulation.
In the internal thermal insulation system, when the greenhouse or indoor temperature drops to the set low temperature limit at night, the thermal insulation quilt is turned off, the heat preservation of the greenhouse is strengthened, the ground radiation heat loss is reduced, the heating energy consumption is reduced, and the operating cost of the greenhouse is greatly reduced; the shade curtain can be opened during the day to make the greenhouse fully daylighting. The working principle is the same as that of internal sunshade, which is made of a lightweight quilt that does not absorb water and weighs between 100 and 150 grams.
Inside the vehicle, the domestic K5 Kaiku dashboard uses a 12.3-inch double screen design, and the full touch operation retains the sunshade and physical button handling compared with the overseas version. The overall sense and the sense of technology have been improved in an all-round way. In addition, the sense of luxury is also optimized compared with the overseas version of the model.
The total amount of energy consumption of a building is mainly affected by various energy-using equipment inside the building and the external enclosure structure that constitutes the building. Due to the vigorous implementation of building energy conservation in China in recent years, the construction technology of building energy equipment and external enclosure structure has undergone profound changes. For example, the roof in the building enclosure structure has evolved into a roof with thermal insulation effect. The external walls also increase the performance of thermal insulation, while curtain walls, doors and windows not only have the performance of thermal insulation, but also installed a sunshade system. This series of energy-saving measures not only improve the working efficiency of the equipment, but also explore and develop some new energy or renewable energy, so the building construction technology needs to be developed and improved synchronously. The author briefly describes the new materials and technologies of building energy saving, as well as their application in construction.
If we choose a very ordinary item, when it feels nothing special, we can choose one or two exquisite accessories. For example, a seemingly ordinary black dress, adding a white headband, will feel much cuter and look good with age. White dress, pure and elegant, choose a straw sunshade hat and a chic straw bag, more pastoral style of fresh and natural, more youthful.
PA has good impact resistance and strength. In the car body, it is mainly used to manufacture wheel front and rear cover, handle, door lock, seat belt fixing hinge, dashboard, fender, sunshade clamp, swing arm of seat back, gear, etc., in which the PA consumption of wheel cover is about 2kg/, which is a big market of nylon. However, when nylon is used as a large component, because the water absorption will cause size change or strength reduction, it can not fully maintain the performance of the parts, so it is necessary to modify PA.
