2) the intelligent sunshade control system uses the brightness sensor to control the sunshade motor. In the automatic mode, the sunshade system can automatically adjust the opening and rotation angle of the sunshade according to the exposure angle of the sun, the intensity of the light, the size of the wind, the quality of the weather and other factors to judge whether to close or not. The system protects buildings and their users from direct sunlight. Summer can block sunlight, block light, avoid excessive heat passing through windows and reduce indoor temperature; in winter, sunlight can be used to heat indoor, improve indoor thermal comfort, adjust the lighting demand of indoor space, and achieve the purpose of environmental protection and saving air-conditioning operation cost.
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.
At the Baitikai Zhoujing vegetable base in Waigang Town, Jiading District, the staff raised the roll film to “ventilate and reduce dryness” of lettuce seedlings in the greenhouse. The reporter saw that the completed greenhouse was covered with black sunshade net and silver insulation, and the sprinkler facilities in the shed were opened from time to time to cool down vegetables. Near noon, the outdoor temperature is nearly 40 ℃, while the temperature inside the shed is 15 ℃ lower than that outside. Lettuce seedlings are green and growing happily.
3. The use or storage of rubber soft joints should avoid high temperature, ozone oil and acid-base environment. Sunny outdoor or windward pipes should be set up sunshade. Rainstorm, rain and wind turbidity are strictly prohibited. It is forbidden to brush paint or wrap thermal insulation materials on the surface of the joint.
At present, spray-free plastics have 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, and there are often small molecular harmful substances that do not fully react, while bioplastics are prepared into automobile interior parts to reduce the amount of VOCs volatilization in the car because of the use of renewable 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.
Placing the sunshade on the central console blocks the bright light to avoid the reflection of the sun (after the sun shines on the control panel of the car, some light reflects some light again, which enters the driver of the eyes. It is very dangerous to blur the body in this case). To a certain extent, the view of the solar light to the owner is that at this level, the use of the solar distribution pad can effectively protect the safety of the owner; in addition, the solar distribution pad can also reduce direct contact between the central console and the sun. When touching the power supply, the owner will not feel very hot.
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.
Before determining the use of the multi-span greenhouse for the project, we should first consider the location of our region, the environmental and climatic characteristics, and the use of the glass greenhouse. For example, in the glass greenhouse for planting and seedling raising in the northern region, the most important work is to improve the thermal insulation performance of the greenhouse as much as possible under the load. We can add an internal thermal insulation system on the top floor of the greenhouse. The glass around the greenhouse should use double-layer hollow glass as much as possible. For example, to build a glass greenhouse in the northwest, we can add Rain Water collection system, external sunshade system and so on. At the same time, planting greenhouse is different from ecological restaurant and leisure tourism agriculture in that the height of planting greenhouse can be 4 meters to 6 meters, and the shoulder height of leisure and sightseeing greenhouse is generally 5 meters to 6 meters.
