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.
1. Greenhouse management should do a good job in greenhouse reinforcement and snow removal. Remove the snow from the roof, increase the light transmission, effectively prevent the snow from crushing the greenhouse, and reduce the freezing low temperature after melting snow. When clearing the snow, you should gently pick and push to avoid piercing the greenhouse film, and carry the snow out of the nursery. The greenhouse that is crushed and deformed should be strengthened and repaired immediately, and if it cannot be repaired, the plants in the shed should be transferred in time, or covered with film, grass curtain or sunshade net to improve the heat preservation effect; it is necessary to do a good job of anti-freezing after snow. There will be frost damage weather after snow. the intima of the greenhouse should be added in all kinds of greenhouses to form internal and external two-layer film for heat preservation, and heating should be carried out in the greenhouse if possible.
for dashboards, door panels, console modules, sub-dashboards, roof storage boxes, sunshades, roofs, air outlets and air conditioners, body parts and other interior components.
At present, new progress has been made in the application of SMC insulation board in automobile abroad. Because of its various functions, it is widely considered to have advantages in structural design, so it is widely used in automobile dashboard, steering gear, radiator system and electronic device system. In addition, doors, bonnets and suitcase covers are also used. The SMC hood is 35% lighter than steel parts. In addition to the above new uses, other applications in automobiles are also used in the production of other parts, such as cab doors, inflatable roofs, bumper frames, warehouse doors, sunshades, An and D posts, body panels, roof drains, shed side strips, truck carriages, etc. Among them, the large amount is used on the outer panel of the car body.
The sunshade board can block the sun and prevent ultraviolet rays. It can play a good role in protecting the items in the car, such as navigators. Do not be lazy when parking, spend a few minutes to block the front and back of the car sunshade, it is best to block both sides better, such a simple operation can bring great benefits.
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.
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.
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 Gansu Ecological Restaurant 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 openers and fans, wet curtains and other equipment need to be applied. For more information about which Gansu Ecological Restaurant is good, please contact Minghao greenhouse Engineering Construction Company directly.
Cili 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.
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.
The maintenance point is a very popular place where our flat-woven sunshade net is solved. The flat-woven sunshade net can be used all the year round, and now the flat-woven sunshade net on the Internet is generally used when the temperature is low in the north. First, where are the advantages of plain weaving sunshade net? 1. Anti-wrinkle and antifouling on towels is the golden section of towels, and its nutrients can be found on towels. Put the towel on the plate, stick it on the towel, and then stick it on the towel. when the dots of the two towels are pulled a few times, the towel can break off the surface of the towel and make a mold. This approach does not require technology.
