Another growth factor related to humidity is light. Blueberries are not particularly strong for it, but moderate light is needed to ensure growth. Generally speaking, a sunshade net should be used to isolate part of the exposure when the sun is strong, so as to ensure that the temperature in the blueberry shed should not be higher than 26 degrees. Especially when the summer temperature is particularly high, you can cover two layers of sunshade net on the surface, otherwise the high temperature will make blueberries stop growing. The sunshade net can be removed when the temperature drops in the evening, and if the temperature is too low, the thermal insulation film on both sides of the shed needs to be put down to increase the temperature in the shed. But leave some holes in the perimeter to strengthen an internal air flow. When the weather is bad, one should pay attention to the heat preservation work, and the other is the drainage work.
The standard lighting of the cab of the new BMW3 series sedan is entirely composed of LED. This includes front and rear reading and interior lighting, as well as glove box lighting, lockers under the central armrest, foot space, sunshades and rearview mirrors and doors in suitcases. Optional ambient lighting can provide atmospheric light for the cabin and can also be adjusted as needed. Additional indirect lighting along the contours of the dashboard and door panel uses precisely positioned LED fiber optic light guides to create a dynamic, unique atmosphere. There are six light colors and eleven luminance combinations,
Third, make full use of all kinds of facilities to create favorable conditions for the growth and cold protection of crops, the greenhouse should do a good job of heat preservation and temperature increase in the greenhouse to ensure immortal seedlings, and actively prepare enough film, sunshade net, straw and other covering insulation materials, in case of freezing weather, do a good job of covering and heat preservation, especially solar greenhouse seedlings, and remove the mulch in time after the strong wind and low temperature to reduce disaster losses.
Do a good job in the production and supply of vegetables in winter and spring. 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.
In the aspect of airbag miniaturization, it is mainly to provide more design space for the peripherals while meeting the lightweight requirements. The miniaturization of the steering wheel airbag improves the degree of freedom in the design of the steering wheel area and helps to improve the overall styling aesthetics of this area, such as the overhead front airbag. Compared with the traditional DAB (steering wheel airbag) and PAB (dashboard airbag) arrangement, the top airbag installs DAB and PAB modules on the roof sheet metal, liberating the steering wheel and front passenger instrument area, and providing space for smart driving, mobile interconnection and other equipment layout. Compared with the traditional front airbag, the top airbag is larger, the bag design is more complex, and the output of the generator is higher, so the airbag assembly is heavier. When arranging, it is necessary to consider the strength of matching with the body sheet metal, the NVH performance, the influence on the front upper visual field, the influence on the sunshade layout design and so on.
Rear bumper, dashboard, etc. Body and body parts: body shell, hard shell roof, floor, door, radiator grille, front end plate, flow stopper, baggage warehouse cover, sunshade, wing panel, engine cover, headlamp mirror, etc. Parts under the engine cover: air conditioner shell, air guide cover, intake pipe cover, fan guide ring, heater cover, water tank components, braking system components, battery bracket, engine sound insulation board and so on. Interior decoration parts: door interior panel, door handle, dashboard, steering rod parts, mirror frame, seat and so on. Such as pump cover and other electrical components and gear sound insulation board and other drive system parts. Suspension parts: front.
PA has good impact resistance and strength. In the car body, it is mainly used to manufacture wheel front and rear cover, handle, door lock, seat belt fixing hinge, dashboard, fender, sunshade clamp, swing arm of seat back, gear, etc., in which the PA consumption of wheel cover is about 2kg/, which is a big market of nylon. However, when nylon is used as a large component, because the water absorption will cause size change or strength reduction, it can not fully maintain the performance of the parts, so it is necessary to modify PA.
In addition to its light weight, due to the high heat resistance of EPP automotive pillows, polypropylene foam is more advantageous than polyethylene foam and polystyrene foam in areas where higher operating temperatures are required, such as sunshades, instrument insulation panels and areas where the temperature between the doors is easy to rise. However, in addition to the field of energy absorption and heat resistance, polypropylene foam also has good thermal weldability, which makes polypropylene foam is also widely used in car sheds, doors, car * panels, carpet support materials, sound insulation panels, door linings and luggage racks, etc., and its good thermal processing type makes it widely used in control boxes, shock-proof boards and other components. In addition, polypropylene foam can also make steering wheel, door inner panel energy absorption protection pad, buffer pad, headrest, toolbox, cushion, dashboard and so on.
On the interior decoration, the design of the circular integrated layered dashboard not only ensures the sense of luxury, but also adds the brushed texture material, highlighting the younger age. At the same time, compared with the previous generation, the central control screen has been upgraded to 12.3 inches and higher definition, which is not only larger, but also easier to operate. The blue atmosphere lights provided in the cockpit create a unique sense of science and technology. One of the favorite designs for young people today is the big canopy. The 2020 VV5 has an oversized 1843*1117mm canopy, which not only enhances the lighting effect in the car, but also brings a more transparent and comfortable visual space to a certain extent. 4.96mm laminated reinforced glass increases the privacy of the car, while the electric sunshade can effectively isolate the external sun, reduce the interior temperature and improve comfort.
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.
In addition, I also know a series of useful automotive supplies, of course, I have not bought it myself, such as car hood, sunshade for front windshield, steering wheel cover, inflatable pump, and wiring, which are actually quite practical and inexpensive.
Due to the use of reflective aluminum foil, sunshade can play a better heat insulation and shading effect. Compared with the car heat shield sold in the market at the same time, it is more flexible and convenient to unfold and fold, and is more suitable for car owners who are in a hurry and are afraid of trouble. When the vehicle is parked, as long as the attached sucker or rely on static electricity, the sunshade can be sucked on the front and rear windshield, which can effectively protect the dashboard, leather seats and other interior equipment while preventing direct sunlight from raising the temperature in the car. At present, in addition to the single sale of front windshield aluminum foil sunshade, but also launched a special car customization service, including windows, rear gear and other positions, the price is not expensive, only tens of yuan to hundreds of yuan. It is worth noting that when buying, it is best to turn on all of them in the light or sunlight to carefully check for damage and leakage.
