Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. Now most new cars are equipped with CD equipment, the main factors affecting the normal work of car audio in late summer and early 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. With the coming of the rainy season, the humidity increases, and there is often a layer of fog on the surface of CD records, which makes it difficult to read the disc. It is best to scrub it every once in a while. If the CD drive is modified, in order to avoid dampness, do not install it under the floor and seat, preferably on the high part of the car body, but not on the rear windshield, too high temperature will accelerate the aging of electronic components and laser head.
The general operating procedure for dashboard cleaning is to clean the dashboard with a dishcloth, and then treat the plastic part of the dashboard with detergent. Finally, use detergent to treat the rest of the dashboard. It should be noted that in the process of dealing with the dashboard, sunshades are used to protect the dashboard from being spoiled by sunlight.
The energy consumption is slightly higher. Therefore, the multi-span greenhouse in the northern region needs to do a good job of heat preservation. Carry out R & D and design in thermal insulation. How to build a three-span greenhouse before determining the use of the multi-span greenhouse for the project, we should first consider the orientation of our region, the climate characteristics, the use of the glass greenhouse. For example, in the glass greenhouse for planting and seedling raising in the northern region, the important work is to maximize the thermal insulation performance of the greenhouse under load. We can add an internal thermal insulation system on the top floor of the greenhouse. The glass around the greenhouse should use double-layer hollow glass as much as possible, and for example, to build a glass greenhouse in the northwest, such as electric sunshade system, electric ventilation system and so on. By adding terminal equipment of the Internet of things, this kind of multi-span greenhouse can automatically start and stop the greenhouse equipment by issuing data acquisition and analysis instructions.
Car front sunshade board the car sunshade board can be put outside as long as the front block, because the sunscreen is installed in the car, the sun will shine through the glass into the car, and the aluminum foil will be reflected back to the car by the glass after reflecting sunlight. The sunshade insulation layer absorbs part of the heat, but blocks the heat in the car and heats up the air in the car, which only plays the role of light insulation and non-thermal insulation.
6. Energy saving and environmental protection: electric shutter windows can achieve the appropriate indoor temperature by adjusting sunshade, which can effectively reduce the heat load of air conditioning, absorb solar radiation energy and reduce heating load in winter, thus playing the role of energy saving and consumption reduction. 5. Heat preservation and heat relief: electric curtains can effectively prevent strong outdoor light, maintain a steady state for indoor temperature, and are more suitable for work.
In the part of storage space, both cars are fully equipped. In addition to conventional front and rear door slots, glove boxes, armboxes, storage compartments and cup holders under the center console, a lot of hidden spaces are optimized, such as the storage space above and below the sub dashboard of BYD Song PLUSDM-i, under the left air conditioning controller and inside the sunshade. The Harvard second-generation dog PHEV is also equipped with more user-friendly storage space, such as four-door cup holder straps, storage slot above the glove box, upper and lower two-story temperature control armrest and multi-stage lifting cup holder.
Automobile manufacturing industry has always been an important consumer market for polyurethane products. The interior decoration of foamed polyurethane plastic for bridge car includes seat cushion, headrest, sound insulation, dashboard, sunshade, door panel, roof lining and so on. Car polyurethane purchased parts include bumper, flow stopper, front and rear ribbon, grille, rear side plate, door panel, fender and so on. The application of polyurethane in automobile is expanding day by day because of its good plasticity and strong application of material properties.
