Tents are necessary ritual items for picnics, and it is critical to take children out with sunscreen. Tents can act as sunshades and allow children to take a nap inside, mainly because no child does not like tents.
Raise the level of mechanized production and liberate labor productivity. First of all, from the environmental control system of multi-span greenhouse, electric sunshade, electric film (window opening) ventilation, electric thermal insulation quilt, electric fan water curtain cooling have been realized, and the environmental control ability of greenhouse is more stable and reasonable. work efficiency is higher, do not need manual operation, just press the switch of the distribution cabinet. Looking at the agricultural production in some backward areas ten years ago and even now, this is a great progress for facility agriculture in our country. Secondly, the interior of our multi-span greenhouse can be equipped with mechanized automatic sprinkler irrigation, integrated water and fertilizer machine, automatic seeder, and even Internet of things control software are now very common systems. greatly improve the production efficiency and achieve precision irrigation and fertilization, water-saving and fertilizer-saving, soilless cultivation and other protection of soil from pollution.
Now? Some cars are equipped with CD equipment, and the main factors that affect the normal work of car audio in autumn are high temperature and humidity. Because of the car stereo? Installed in the upper part of the dashboard, the sunshade is more effective in order to avoid the exposure of the sun. 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? The road burns down the mainframe.
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.
These parts are mainly produced by supporting manufacturers. Interior design includes dashboard, steering wheel, seat, seat belt, airbag, carpet, sidewall interior decoration, sunshade panel, handrail, car rearview mirror and so on. Exterior design includes front and rear bumper, glass, door anti-collision decoration strip, intake grille, luggage rack, skylight, rearview mirror, door structure and accessories and sealing strip.
From the point of view of yield, it is mainly the anti-freezing damage of low temperature in winter. This technique is relatively easy for greenhouse loquat. For Jiangsu and Zhejiang areas, it is necessary to prepare double-film covering materials after entering December, and double-film mulching should be carried out when the cold air comes or the lowest temperature drops below 5 degrees Celsius. When the lowest temperature affected by cold air is below 0 degrees, further heat preservation work needs to be done on the basis of double film. The main measures are as follows: first, sprinkler irrigation should be carried out during the day to increase soil water content and humidity to increase heat capacity. the fog produced by the cooling of high humid air can slow down the temperature drop; second, build a sunshade net on the loquat tree. Third, the heating treatment is carried out in the shed, and the heating time is from the second half of the night to the morning. The prevention index of frost injury during flowering is to keep the temperature in the shed above 0 degrees.
Glass curtain wall: the curtain wall of the main terminal is in the form of a 18-meter unit, which is divided into 3 small units, two self-supporting columns of the curtain wall, which are placed on the inside of the curtain wall, each column is built-in stainless steel downcomer, the first main column is covered with stone, and the indoor and outdoor ceiling runs through to the outside of the curtain wall; the finger corridor still takes 9 meters as the unit system, and the square column is used for thermal insulation and waterproofing, and the downwater pipe is placed in front and wrapped in stone. The horizontal sunshade is 9 meters long to bear the horizontal wind load, and the gravity load is suspended by stainless steel poles in each vertical seam of glass. The roof boat-shaped large daylighting roof adopts the scale of 1.5X3 meters per piece of glass, and the rest of the strip or distance daylighting roof glass uses a single piece of 1.5X1.5 meter safety scale. The aluminum plate rain canopy is arranged above the curtain wall on both sides of the corridor, and the appropriate lap length is set at the connection part of the corridor to ensure the integrity of the appearance.
