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.
two。 Sunshade. The membrane structure Suzhou parking shed adopts polycarbonate material with high impact resistance, and its strength is about 200 times that of glass. The raw materials are imported from Germany and processed in China. Through the double-sided co-extrusion process, the anti-ultraviolet material (UV) is added, which can effectively block more than 98% of the ultraviolet rays, protect the car surface paint, effectively control the continuous rise of the interior temperature, and in direct sunlight. The temperature in the car can reach more than 60 ℃ and can be effectively reduced to about 40 ℃ after installation. At the same time, it also has flame retardant effect, and can be used normally for more than 30 years in the environment of-30 ℃ to 60 ℃ (137 ℃ thermal deformation). The downcomer is made of high-strength aluminum alloy and has a unique user-friendly design to avoid the second pollution to the car and you when the roof water falls to the ground. The structure is reasonable and easy to clean, and it is convenient for the Suzhou parking shed with membrane structure to remove dirt from the pipe.
Temporary shading is the installation of lightweight curtains, plastic blinds or pendants at the window, while sexual shading is the installation of sunshades in various forms at the window. The facilities of sexual sunshade system can be divided into active form and fixed form according to whether the components can be disassembled and moved. In recent years, the active sunshade system is widely used in buildings in our country, and the angle of the sunshade can be adjusted freely according to the annual seasonal change or the all-day sunshine change. Because of the strong flexibility of this facility, it can also be easily removed in order to get sunshine and avoid blocking the sun in the cold season. Today, with the rapid development of science and technology, there are all kinds of heat reflection glass, such as sunlight control film, coated glass, low emissivity film glass and so on.
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 has been widely used in automobile interior and exterior decoration parts, such as bumper energy absorber, sunshade, tool box and so on.
Conclusion: if you want to breed well, enclosure is very critical, so you should consider it at the beginning, all kinds of facilities are well prepared, and at the same time, you have to ensure internal ventilation and temperature. Do a good job of keeping warm in winter, while building a sunshade or planting some trees to keep out the shade in summer can lower the internal temperature. In this way, we can effectively avoid getting sick because of environmental problems, and internal disinfection is also very critical. Build a relatively large disinfection pool, drive them inside regularly, and do a good job of disinfection. At the same time, some drugs should be sprayed regularly in every corner. It is guaranteed to provide the most suitable residence without damaging the ecological environment, which can improve its quality and ensure faster growth at the same time.
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.
As for your own equipment, you should wear hiking shoes or light sports shoes, a waterproof suit, and a climbing stick if you want to go camping in the mountains. Other small bits and pieces should also be considerate, including sweat socks, sunshade hats, gloves, glasses, backpacks and so on. Then there are picnic utensils, including gas tanks, stoves and simple aluminum pots and rice pots are also indispensable. As for specific food, just prepare enough according to your personal preference and how long you plan to stay, but water is very important. You can also bring some water purification tablets with outdoor kettles and thermos.
Internal thermal insulation system when the greenhouse or indoor temperature drops to the set low temperature limit at night, turn off the thermal insulation quilt, strengthen the heat preservation of the greenhouse, design and construction of the solar greenhouse greenhouse, reduce the ground radiation heat loss, reduce the heating energy consumption, and the design and construction of the ecological restaurant, greatly reduce the operating cost of the greenhouse; in the daytime, the shade curtain can be opened, and the design and construction of the multi-span greenhouse greenhouse can 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.
c. Functional class. Including car body insulation materials, anti-collision fillers, dashboards, sundries, indoor shelf panels or rear windowsill panels, sunshade panels, wheel cover covers, engine cover covers, etc.
The zero gravity seat can realize the stretching ride with a golden angle of 110o, electric adjustment, massage and other functions are readily available. Under the auxiliary dashboard, a large open storage space can be placed for items such as cosmetic bags, high heels and so on. At the same time, the sunshade above the passenger car is equipped with LED soft light makeup mirror, which makes the popular “goddess co-driver” very comprehensive.
In addition to selecting appropriate insulation materials, the correct insulation treatment technology is adopted to form a complete protective layer on the insulation exterior. For protection against sunlight, a sunscreen can be installed at the top of the shell, and there should be a certain distance between the sunshade and the shell to avoid direct heat transfer. In recent years, the cooler is often put on the stator. In order to avoid the condensation of the motor, a moisture-proof heater can be installed. Outdoor motors can be treated similarly according to tropical motor insulation.
