It is necessary to do a good job of heat preservation at night and ventilation and humidity reduction during the day. The night temperature in early spring is still low, which needs to be covered with grass curtain, sunshade net, non-woven fabric or multi-layer mulching; the temperature rises rapidly during the day, coupled with the current high humidity in the field, so it is necessary to timely control and adjust the indoor air humidity and temperature in the shed. On a sunny day, after the temperature picks up after 08:30, ventilation should be carried out gradually, and the mulch such as non-woven fabrics should be removed in time to increase the light; the shed should be closed and the warmth should be covered before 4 p.m. In case of cloudy and rainy weather, it is still necessary to properly ventilate during the day to reduce the humidity in the shed. In addition, in the alternate season of late winter and early spring, the weather changes greatly, so we should pay close attention to the weather changes to prevent the occurrence of late spring cold. After the middle of April, the average temperature is stable above 15 ℃, which can remove the inner shed, prolong the opening time of the outer shed, increase the light time and intensity, reduce the humidity in the shed, and control the occurrence and prevalence of diseases such as leaf mold and gray mold.
Generally speaking, about 150000 of the models in the interior of the advanced sense and materials, there will not be so much sincerity. In terms of materials, the X90 dragon uses 118 kinds of interior materials for dashboards, carpets, door guards, ceilings, posts, steering wheels, damping mats, seats, sunshades, etc., and is also equipped with CN95 air conditioning filter elements, dual-channel laser sensors and negative ion generators to ensure the air quality in the car. In terms of these materials and configuration, it can be said to be quite kind.
There is no bulge on the surface of various devices in the car cockpit, the material is soft and elastic, and the sharp corners, protruding edges and protruding parts can be reduced as much as possible, which can reduce the injury suffered by the passengers in the event of collision. The range of interior softening includes prominent accessories such as steering wheel, dashboard, side circumference, roof, seat, floor and sunshade. The steering wheel of some cars can contract during a collision, and some seats have headrest to prevent head injury when the rear is hit. These are all designs that can improve the safety of the car.
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 Jining intelligent greenhouse requires 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 Jining intelligent greenhouse, please contact Minghao greenhouse Engineering Construction Company directly.
Double-layer glass can achieve the same area in terms of heat preservation and thermal insulation, the temperature of the building is uniform and asymmetrical, and there is no problem with the thermal insulation performance of all-glass. The outdoor frame of the solar roof works under all-glass sunshade, so it is divided into electric glass and machine glass to prevent rain leakage in rainy days.
Among them, TPU and other polyurethane products can give full play to their unique advantages and have been used in a variety of automotive body parts, including car seats, cushions, headrest, floor mats, dashboards, sunshades, doors, ceiling linings and other internal parts as well as sound insulation and noise reduction materials, sealing materials and so on.
for car carpets (floor mats), car cushions, safety seats, sun gear and decoration products, surface coverings, curtains, sunshade products, interior decoration products, etc.
In addition to its light weight, polypropylene foam has higher heat resistance, polypropylene foam is more beneficial than polyethylene foam and polystyrene foam on platforms requiring higher operating temperatures, such as sunshade panels, instrument insulation panels and places where the temperature between the doors is easy to rise.
The best temperature for the growth of honeysuckle is between 18 and 28 ℃, and the temperature difference among the four seasons in many areas is relatively large. Therefore, in order to promote the better growth of honeysuckle, it is necessary to strengthen the management of field temperature. We can reduce the field temperature by watering and building sunshade, and can also wrap plastic and build a greenhouse to keep warm.
Figure 3 is a schematic diagram of the patent application trend of the third-tier technology branch in the field of internal and external decoration. The growth trend of patent applications related to seat technology and headlamp technology is more obvious. The seat is the first component to evaluate whether the car is comfortable or not. Headlights are also an important part of safe driving. From the overall trend, the number of patent applications for the above technologies has increased rapidly since 2005. There is also a growth trend in dashboards and center consoles, rearview mirrors and bumpers, with slower growth in patent applications compared with seat and headlight technology. The number of technical applications such as sunshade panel and interior panel, radiator grille and spoiler is less, and the application trend is relatively flat.
