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.
The heat preservation performance of agricultural film is poor, especially the noon temperature in summer and autumn is easy to be too high, so it is necessary to do a good job of cooling: suitable for feeding wet leaves. It is easy to cause mulberry leaf withering after high temperature and ventilation in the shed. Wet leaves can be fed at noon on a sunny day and air spray with effective chlorine concentration bleaching solution is used to replenish moisture and prevent disease. Increase ventilation. After sunrise on a sunny day, open the film on both sides of the greenhouse for ventilation, and put down the film on both sides to keep warm when the temperature in the shed drops below the suitable temperature for feeding in the evening. When the temperature is high, ventilate day and night. Put down the sunshade net on both sides of the greenhouse on rainy days and lift the film on both sides of the greenhouse to facilitate ventilation.
1. Greenhouse management should do a good job in greenhouse reinforcement and snow removal. Remove the snow from the roof, increase the light transmission, effectively prevent the snow from crushing the greenhouse, and reduce the freezing low temperature after melting snow. When clearing the snow, you should gently pick and push to avoid piercing the greenhouse film, and carry the snow out of the nursery. The greenhouse that is crushed and deformed should be strengthened and repaired immediately, and if it cannot be repaired, the plants in the shed should be transferred in time, or covered with film, grass curtain or sunshade net to improve the heat preservation effect; it is necessary to do a good job of anti-freezing after snow. There will be frost damage weather after snow. the intima of the greenhouse should be added in all kinds of greenhouses to form internal and external two-layer film for heat preservation, and heating should be carried out in the greenhouse if possible.
If the temperature rises in a straight line, you will prefer to wear a simple and comfortable match. The loose petal collar blouse is fresh and cool, and the A-shaped denim skirt is quite friendly to the pear-shaped figure, with small flat-soled white shoes. Hot summer sunscreen umbrella is indispensable, sunshade shape is not wrong, coupled with a bright lemon bag, a set of blue, pink and yellow macarons, daily commuting to the street.
Sunscreen is generally divided into sunshade and sunshade, side block, the price difference is about 15 yuan, window shade and umbrella can cover the entire windshield, but can not cover the window, the side block only covers the four windows of the car, suitable for driving or driving when using
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.
Shaoguan pp tank processing drawings at present, spray-free plastic has been successfully used in the automotive field of side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics are generally synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics, due to the use of renewable raw materials with low toxicity and low harm, greatly reduce the amount of VOCs volatilization in the car after being prepared into automobile interior parts. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic.
