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.
OR-2 at present, spray-free plastic has been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. 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, which are often harmful to small molecules that do not fully react, while bioplastics are prepared into automobile interior parts for VOCs volatilization in large vehicles because of the use of renewable raw materials with low toxicity and low harm. In addition, this bioplastic can be decomposed to facilitate subsequent recycling, so it is a more environmentally friendly type of plastic. 00 portable packing machine which packing belt is suitable for use:
A single material or laminated composite material used in automobile interior parts Such as cushions, seat backs, seat covers, seat belts, headrests, handrails, removable folding roofs, all decorative linings (including door panels, side panels, rear panels, roof linings), dashboards, debris boxes, indoor shelf panels or rear window sills, curtains, floor coverings, sunshades, wheel cover coverings, engine hood coverings and any other indoor organic materials It includes materials such as fillers and cushioning devices that absorb collision energy during a collision.
Sunshade full-cover type windproof, waterproof and UV-proof, tires suitable for all terrain, five-point embracing seat belt design, as well as 2-wheel mode, picnic mode, each design is very practical, while ensuring the safety of the baby, more convenient.
If we choose a very ordinary item, when it feels nothing special, we can choose one or two exquisite accessories. For example, a seemingly ordinary black dress, adding a white headband, will feel much cuter and look good with age. White dress, pure and elegant, choose a straw sunshade hat and a chic straw bag, more pastoral style of fresh and natural, more youthful.
Zhang Wei, deputy general manager of the Urban Deputy Central Station Integrated Hub Construction Management Co., Ltd., said that the “Jingfan” roof has built a perforated sunshade, which balances the cold and heat load and can rationally control the indoor light and heat environment. It is estimated that by adopting the “Beijing sail” scheme, the heat load can be reduced by 5.2 million kilowatt-hours per year, which is equivalent to the summer cooling capacity of 3200 household air conditioners, and the power consumption of lighting can be reduced by about 486000 kilowatt-hours per year.
