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.
In terms of interior decoration, domestic head enterprises are almost “monopolized” by the Yangtze River Delta. Ningbo Jifeng shares, Huaxiang, Topu Group, Shanghai Yanfeng Automobile, Daimei shares, Jiangsu Xinquan shares and Changshu Auto Decoration cover the one-stop industrial chain from seats, sunshades, dashboards to the entire internal and external decoration system.
As we all know, temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.
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 specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is good to use the sunshade to resist the scorching sun and avoid the direct sunlight.
EPP (polypropylene) foam is a foam material formed by foaming with polypropylene resin as the matrix. It not only has high heat resistance, high impact energy absorption capacity, good resilience and thermoformability, but also can be recycled. It is widely used in bumper, bottom guard, sunshade and other automobile interior and exterior decoration parts. EPP is a kind of high crystalline composite material with excellent performance, which has become the fastest growing and most environmentally friendly anti-pressure buffer thermal insulation material because of its unique and superior properties. EPP can be used in construction, packaging, automobiles, sporting goods, toys, toolboxes, food packaging boxes, household appliances, daily necessities and so on. And EPP is included in the “made in China 2025” key areas of technical materials, known as “green” foam materials.
In addition, if there are conditions, rain shelters, sunshades, street lamps, leisure chairs and other traffic auxiliary facilities can be set up on the pedestrian interchange, which is not only convenient for travel, but also provides a place for urban residents after dinner.
A large curved photovoltaic array of Anhui refrigerated containers is listed as a residential unit to provide energy and can also be used as a sunshade to reduce the heat gain of the house. Under the basic living structure framework, different layout designs can meet different life function arrangements. At present, the construction site mobile room is a commonly used convenient house, which can be used as a short-term office, of course, there are certain requirements for its comfort, and the sound insulation effect is also a standard to judge the comfort. However, in the sound insulation effect, the use of sandwich color steel plate wall, and the sandwich material can play a role in thermal insulation, but the anti-noise performance is not very good.
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.
Although, there are some minor complaints in the process. “before the introduction of the policy, I saw someone cooking hot pot on the lawn, hurting the grass. When they left, they also left some rubbish. ” Ms. Mak, a citizen, said. In view of this situation, according to the person in charge of the Yuntai Garden Management Center of Baiyunshan Scenic spot, the tent area of the park will be in charge of a fixed area, a fixed period of time and a special person. At present, two large lawns in Yuntai Garden are open for citizens to set up tents from 10:00 to 4 pm on weekends and holidays. Members of the public can set up tents and picnics. The garden will also provide sunshade facilities and designate garbage dumping areas. Kites and fire are prohibited on the lawn.
Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Jilin solar energy greenhouse needs 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. For more information about Jilin solar greenhouse manufacturers, please contact Minghao greenhouse Engineering Construction Company directly.
At the event site, volunteers consciously stuck to their posts and listened to the unified arrangements of the propaganda Department of the County Party Committee, the Youth League County Party Committee and the Youth Volunteer Association, wearing masks, red waistcoats and ribbons emblazoned with Dancheng Associated Society to help maintain order around the examination room. free cooling supplies such as bottled mineral water, paper, hand folding fans and towels are provided for college entrance examination candidates and accompanying parents. At the same time, sunshade tents, chairs and tables are placed at the service point to accompany parents to rest. During the waiting period, young volunteers take the initiative to communicate with the parents of examinees, by popularizing financial knowledge such as illegal fund-raising and telecommunications fraud, so as to alleviate the tension and anxiety of parents in hot weather and provide them with a comfortable environment for accompanying exams.
