A shade arch shed was built in the field. The height of both sides of the arch shed should be higher than 25cm from the nursery bed and above 45cm in the middle. After covering the colorless plastic film, it is covered with about 65% sunshade net, and the edge is compacted to prevent air leakage and ventilation. When the temperature in the shed reaches or exceeds 40 ℃ during the day, remove the film at both ends or in the middle to reduce the temperature to prevent the seedlings from being burned by high temperature; do a good job of heat preservation and moisture preservation by compacting the edge of the shed in winter.
The interior and exterior decoration of the car includes four subsystems-interior decoration, exterior decoration, seat and passive safety. The interior includes dashboard, auxiliary dashboard, pipe beam bracket (CCB), air conditioning duct, ceiling, carpet, heat insulation mat, door trim panel, side trim panel, etc.; exterior decoration includes internal and external rearview mirror, front and rear bumper, sunshade, spoiler, luggage rack, body exterior decoration, body bottom guard, etc.; seats include main and passenger cars, two or three rows of seats; passive safety includes seat belts and airbags, etc.
The shading design should be based on the climate characteristics of the area, the use requirements of the room and the orientation of the window. The effect of sunshade facilities on shielding solar radiation heat not only depends on the shading form, but also depends on the structure, installation location, material and color of sunshade facilities. The shading device can be set to permanent or temporary. Permanent sunshade devices include setting various forms of sunshade panels in the window; temporary sunshade devices include lightweight curtains and various metal or plastic blinds in the window. Permanent shading facilities can be divided into two types: fixed and movable. The movable sunshade facility can adjust the angle of the sunshade according to the change of season, the time of day and the gloom of the sky. Shading measures can also use a variety of heat reflection glass and coated glass, sunlight control film, low emissivity film glass and so on.
When choosing an intelligent greenhouse, many customers confuse the difference between the shading system in the multi-span greenhouse and the internal thermal insulation system, and some businessmen mislead the internal thermal insulation system and the internal sunshade system as a set of system use. “the difference between the multi-span greenhouse internal shading system and the internal thermal insulation system, to explain the difference between the two, the difference between the multi-span greenhouse shading system and the internal thermal insulation system. 1. The similarities between the shading system in the multi-span greenhouse and the internal thermal insulation system are that the two have the same transmission system; the components and working principle of the transmission system, 1. Special deceleration motor for transmission mechanism, gear and rack drive, drive rod, transmission rod. The motor drives the drive shaft through the transmission mechanism, the drive shaft drives the drive rod to move parallel on the screen wire through the connector, and the drive rod pulls one end of the curtain to unfold, and the stroke limiter switch is all unfolded.
Facility vegetable production should do a good job in facility repair and heat preservation, adopt measures such as multi-layer film mulching and adding thermal insulation quilts to strengthen facility heat preservation, and if possible, heating equipment can be used to increase temperature. completely eliminate the hidden dangers of production risks such as old facilities, heating charcoal and fire. Conscientiously implement measures such as clearing communication canals, timely uncovering and replenishing light, scientific fertilization and water pipe, etc., and make use of fine weather to restore ventilation and dehumidification in time after rain and snow, reduce the humidity of the shed, and reduce the occurrence of diseases. Vegetables in the open field should clear the ditch and manage the soil moisture in advance to prevent stagnant water in the field; if possible, cover materials such as plastic film, non-woven cloth or sunshade net should be directly covered with floating surface to prevent cold; mature vegetables should be harvested and listed in time to ensure that the main vegetable products are not out of stock and unbroken, so as to promote market price stability.
The richness of the configuration is also an important factor to attract the review team. They believe that at half the price of a luxury car, it will have a full-time all-wheel drive, front and rear seat heating, wireless charging and a second row of private sunshades. In the light-colored interior version, the matte wood-like decoration carves a half-moon on the passenger side of the dashboard and then extends precisely to the upper part of the door, visually connecting the entire front row.
3. The use or storage of rubber soft joints should avoid high temperature, ozone oil and acid-base environment. Sunny outdoor or windward pipes should be set up sunshade. Rainstorm, rain and wind turbidity are strictly prohibited. It is forbidden to brush paint or wrap thermal insulation materials on the surface of the joint.
The integrated sunshade can be used to the south, south by east and south by west, shielding the incident angle is relatively small, and the sun shining obliquely from the side direction of the window, the sunshade of the baffle structure is more suitable for the windows in the east and west, it can block the orthographic window and the sunlight with relatively low incident angle. The building raw materials used in many types of sunshade structures are concrete, aluminum alloy, zinc-steel alloy, wood and so on. Because zinc-steel alloy has relatively light weight, good durability, heat resistance and low thermal conductivity, the manufacturing process is also very good, so zinc steel shutter profile is the most commonly used in all sunshade blinds.
