Audio failures are generally divided into two categories: one is caused by improper use, and the other is caused by the weather. The main factors that affect 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.
According to the different use characteristics of famous plastics, the production of food plastic products in Quzhou City is usually divided into three types: general plastics, engineering plastics and special plastics. First, general-purpose plastics generally refer to plastics with large production capacity, good formability, cheap price and wide use. The reason of shrinking pit is the same as insufficient filling, which can be solved by excess filling in principle, but there will be stress. Attention should be paid to uniform wall thickness in design, and the wall thickness of reinforced ribs and convex columns should be reduced as much as possible. The treatment of the overflow edge should mainly focus on the improvement of the die. On the other hand, in the forming conditions, we can start to reduce the liquidity. The representative parts on the car are dashboard, rearview mirror, bumper, seat cushion, headrest, steering wheel, instrument panel anti-vibration pad, pillar decoration, front roof lining, window frame, ceiling and side roof frame decoration, door liner, sunshade board, rear roof frame decoration and so on.
There are many kinds of automobile interior materials, but considering the necessity of antibacterial testing, the materials that need to be paid attention to belong to the parts that are in frequent contact with the human body, respiratory contact or easy to be contaminated. This kind of parts mainly include steering wheel, seat, sunshade, shift handrail, dashboard, auxiliary dashboard, seat belt, door interior panel, handrail, ceiling, carpet, air conditioning, air duct and air outlet, etc.
First, automatic telescopic sunshade, thermal insulation and cooling, the seats of the car are generally leather, and long-term exposure to the sun will lead to excessive temperature in the car, which can easily lead to aging and hardening of the leather material in the car. but now the car sunscreen tools can play a good role in thermal insulation and cooling to protect the car. Car automatic telescopic sunscreen front and rear window shade this is a very popular automatic windshield sunscreen, the installation is very simple and convenient, put it away directly when not in use, and open it when you need it. When the car is parked in the sun, it can protect against ultraviolet rays and prevent the car from getting too hot.
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.
The heat preservation of the greenhouse is very high in summer, so all the vents around the vegetable greenhouse must be opened. If the temperature is too high, the top of the vegetable greenhouse can be covered with sunshade net to cool down. In the sunny day, the temperature in the shed should be measured in time. As soon as the temperature rises to more than 30 ℃, open the ventilation vents on both sides and adjust the vents to stabilize the temperature in the shed at 25 ℃-30 ℃ as far as possible. Take light enhancement measures to increase light intensity and prolong light time; select agricultural film with high light transmittance and wipe it frequently to ensure that the surface of agricultural film is clean; cover white plastic film; hang reflective curtain on the back wall; prune and pick leaves in time to enhance the light transmittance of the field.
Of course, the work of solar greenhouse requires the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied.
