Introduction to the maintenance of blinds in daily life, it is recommended to use special dedusting equipment to wipe off dust with a semi-damp sponge or a soft dishcloth, and the gentle and smooth operation of wiping moisture with a dry cloth can prolong the service life of the blinds, and regularly use candles to smear back and forth on the rope several times, which can make your lifting operation easier. Rain-proof shutters are used in computer rooms or other public places that need ventilation and rain protection, heat insulation and air flow regulation, and are composed of rain-proof blades with water collecting ditches, side frames with drip frames and streamlined regulating blades. It not only has the advantages of single-layer rain-proof shutters, but also the staff can adjust the opening of rain-proof shutters according to the indoor temperature or ventilation demand. Single-layer rain shutters are divided into vertical and horizontal, mainly used for large shopping malls, exhibition halls, garages and other places of the facade and top sunshade, also has the role of anti-theft insurance.
Generally speaking, the horizontal sunshade with an outdoor south elevation of 45 °can easily cover 68% of the solar radiation heat. Installed in the window inside the curtain, soft 100 pages and other sunshade facilities, most of the solar radiation heat absorbed by it is distributed to the indoor air. The sun visor installed on the outside absorbs most of the radiant heat and distributes most of the outdoor air, thus reducing the impact on indoor temperature. Therefore, the use of external sunshade (sunshade) is the best way to save energy in buildings.
Felt quilt in order to achieve a good thermal insulation effect, can be covered with a layer of non-woven fabric or sunshade net and other thermal insulation materials, in the presence of very low temperature weather, you can choose to add “shed” to heat preservation. Although the work of heat preservation in cloudy days is important, it should not be blind and needs reasonable regulation and control. In a snowy day, the night temperature is easy to rebound, the plant accumulates less photosynthetic nutrition during the day, but consumes more at night, so it is easy to grow poorly. Therefore, it is very important to regulate the night temperature in overcast, rainy and snowy weather.
The big tree by the river has become a choice for many tourists to have a picnic. A large area of open grass, next to big trees sunshade, sitting by the river all afternoon, it is very comfortable ah.
At present, spray-free plastic has been successfully used in automotive parts such as side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts. Bioplastics bioplastics are produced under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Commonly used plastics are generally synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics are prepared into automobile interior parts with large amount of VOCs volatilization in the pulley because of the use of renewable raw materials with low toxicity and low harm. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
To reduce direct sunlight radiation from roofs, walls, windows and indoors through windows, eaves, sunshades (awnings), coated glass, etc., can be used to reduce the radiation heat of sunlight absorbed by external walls and roofs, and light-colored exterior wall finishes can be adopted. the insulation layer is set on the outside of the external wall and roof, or overhead roofing and other measures.
Sunshades protect telescopes, reflecting light and background heat from the sun, earth and moon into space. The observatory must maintain a low temperature in order to complete groundbreaking scientific research in infrared light, which is invisible to the human eye and feels like heat.
2. Supplement labor protection supplies. The sanitation station has invested in the purchase of 72 labor protection products for sanitation workers (sunshade hats, towels, soap, etc.), in order to protect the safety and health of sanitation workers, enrich the style of labor protection products for sanitation workers, and improve the grade; purchase big bamboo brooms for replacement and use every month to ensure that the cleaning work of sanitation workers is carried out in an orderly manner.
