This kind of agricultural film usually results in poor light conditions in the greenhouse, and the temperature is relatively low and the humidity is relatively high, which aggravates the diseases and insect pests to some extent. 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.
Because the car audio is mostly installed in the upper part of the dashboard, in order to avoid the exposure of the sun, the effect of using sunshade is better. If the door and window sealing strip is not strict, it should be replaced, otherwise the loudspeaker is easy to rust and damage, or even cause short circuit to burn the main engine. The specific heat of the circuit board and plastic components in the car audio mainframe is different, so it is affected by the temperature change to a different extent. In the scorching sun, it is good to use the sunshade to resist the scorching sun and avoid the direct sunlight.
More installation method has a double-sided detachable, double-sided detachable installation node, which is a good node for bracket installation. At present, the maintenance of ultra-polymer photovoltaic support bearings is developing rapidly. If there is no such use of pressure and mechanical fixation, it is likely to produce a lot of defects. Such as irregular axial loosening, axial pressure deformation, installation collision, photovoltaic support instability and so on. Erguna connected greenhouse tube structure of a variety of assembly plants can use these pipes, electrical equipment to form a workspace, does not require a large amount of investment. This automatic device mainly relies on the computer as the control center to control the facilities such as skylight, sunshade, heat preservation, wet curtain / fan cooling, spray drip irrigation or drip irrigation, seedbed and so on. Of course, the automatic device can not only rely on the control of the computer, it also has acquisition and control.
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.
The main contents are as follows: 1) the structural design of the window should be reasonable. In the design of the building window, it should not only reflect the control effect of the window on sunlight, but also limit the volume ratio of the window to the wall. If the window area of the building is relatively large, endothermic glass or heat reflection glass can be used, and other shading measures such as balconies, curtains and sunshades can also be taken. If the outdoor temperature is low, natural air can be used as a direct source of energy. Therefore, when designing the construction of the window, you can set a natural pass on it that can open the shoulder;
Some car owners park their cars outside in the wind and rain. The front gear, rear gear and windows on both sides of the car are made of glass. The summer sun shines into the car through the glass, which will soon raise the temperature inside the car. Then we can give our car “sunscreen”, that is, we can use car sunshade to block the sun in all directions, so that the light can not enter the car, which can reduce the temperature in the car to a certain extent. it can also prevent leather seats and dashboards from being damaged by ultraviolet rays. Second, driving is not afraid of hot
Product features: stretch freely and quickly, as long as the car is parked outside in hot summer, the temperature in the car is always unbearably high, and even the cushions may be too hot to sit down directly. If you want to save the sunshade installation and disassembly program, there must be a retractable sunscreen that can be easily opened to block the sun, and the car can be quickly folded to one side before moving without taking up too much space. By the way, this product also has a multi-function number plate to provide the car owner with an immediate stay phone. Although the manufacturer stated that it will not block the view of the car, but because it is fixed next to the A-pillar, some car owners may feel that there is a foreign body in the line of sight, so it will be safer to choose other styles if they have doubts.
The structural design of the front panel may seem strange at first glance. The “S” urban layout seems to be a bit pinched, but what is worth plugging is that it belongs to a category that is more and more attractive and has a lot of dimensions and trends. the artificial intelligence construction project of the whole dashboard has been carried out very well. The black and white origin of the cloth and the nickel sunshade reduces the hierarchical and advanced sense of the interior, and the lack of sleep in the car can have an obvious sense of luxury, but it has won the Anderson Top Ten Interior Award for modularization. The expansion goes far beyond the evolution of TNGA from maneuverability to higher security. In 2006, Camry was introduced into domestic production capacity, and after it was officially announced in 2007, Camry was renamed Camry. Toyota Camry still sold its products in China by means of imports from the United States a long time ago. However, the majority of domestic customers can not stop its domestic temperament, sales are booming, and the price is congested.
First, the sanitary disinfection of the enclosure should be done well. The manure should be cleaned up in time every day and transported to a place far away from the cattle farm for accumulation and fermentation, and the cowshed should be disinfected regularly, usually once every 3-5 days in summer and autumn, and once every 7-10 days in winter and spring. Second, strengthen window ventilation to reduce toxic and harmful gases such as humidity, dust, ammonia and carbon dioxide in the enclosure. Third, to ensure that the barn temperature is suitable, sunshade net is set up to cool down in summer, and greenhouse is built to keep warm in winter, only beef cattle can grow better at a suitable temperature.
This kind of flower planting greenhouse is widely used in most areas, especially in the south. The single-family arch shed is mainly made of plastic-coated steel pipe or galvanized steel pipe, the surface is covered with film, and air vents are added on both sides. The utility model has the advantages of simple structure, low cost, easy construction and maintenance, long service life and strong resistance to wind and snow load. Its big deficiency is that the heat preservation capacity is low and the operation cost is high in winter, so it is suitable for breeding non-tropical flowers with low temperature requirements. Of course, we can add two-layer film on the original basis, increase the curtain machine quilt and other thermal insulation equipment, sunshade can effectively improve the arch shed temperature.
The Edge office building, built on a 15-meter-wide site with a total of 10 stories, is currently the largest building with a solar wall facade in Canada. The 560 photovoltaic panels on the facade of the building can meet 80% of the power needs of the building. At the same time, the building is also connected to the local urban power grid to transfer its excess electricity. The design of the building includes two insulated three-layer glass and four-layer glass systems. The sunlight from the north side also fully meets the needs of indoor lighting during the day. The north window does not need to install any blinds to withstand the high temperature caused by the sun in summer. The rear end of the office building is also equipped with a thermal isolation balcony and sunshade to better control sunlight exposure.
