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.
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.
In addition to picnics, how to make such activities more comfortable and “classy”? with the help of escalating demand, the form of camping has become a favorite of consumers. Sunshade, delicious food, a few folding chairs, plus barbecue and charcoal fire, in such an atmosphere, not only the activities become more enjoyable, the photos also become more exquisite, which camp scenery is more beautiful, how to wear more film It has become a topic of skyrocketing searches on Little Red Books.
According to the management of medium-and long-term weather forecast, in case of continuous low temperature, the temperature of the mushroom house / shed should be kept above 8 °C ~ 10 °C. The main measures for heat preservation and warming include: thickening the roof cover at night; hanging blankets on doors; closing doors and windows for heat preservation in the morning and evening; opening doors and windows around noon in sunny days; opening only leeward vents for short-term ventilation in rainy and snowy weather; in cold or windy weather, close doors, windows and vents to prevent cold air from attacking. When the weather is fine, open the cover to increase the temperature of the light, when the light is strong, it is best to set up a sunshade net under the greenhouse film and above the bacterial stick to protect the light and heat. If there are heating facilities such as hot air stove, the temperature of the mushroom room / shed can be increased by heating, but attention should be paid to prevent the smoke from being discharged into the shed and cause poisoning. In addition, the ditch cleaning and drainage of the mushroom shed should also be done to reduce the humidity in the greenhouse in the rainy season and improve the mushroom quality.
A part of the diaphragm is coated with a transparent reflective film, and the image and data on the dashboard transmitted from the projector can be displayed on the diaphragm as needed, which is convenient for the driver to observe, and the driver does not need to look down at the instrument when driving. The image shows that if the intelligent glass cooperates with the infrared image display system, the driver can see clearly the objects around the 2km in front of him on a foggy day. The photoelectric sunshade roof glass can automatically absorb, accumulate and use solar energy to drive the car fan when the car is driving or parking, and it can also continuously recharge the car battery.
The interior part is composed of instrument panel and top cover lined with sunshade panel, door guard plate, etc., its function is to increase the aesthetics of the interior shape, improve comfort, and ensure the safety of passengers. The main functions of the dashboard are as follows: install all kinds of instrument variable speed joystick and other auxiliary parts. There is no danger of bulge and acute angle caused by impact, and it can effectively produce deformation and damage to protect the occupants.
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 under the influence of microorganisms using original plants as raw materials, such as sugar cane, corn and so on. Commonly used plastics are usually synthesized from petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics use renewable raw materials with low toxicity and low harm, so the amount of VOCs volatilization in the car is greatly reduced after being prepared into automobile interior parts. In addition, this bioplastic can be broken down to facilitate subsequent recycling, making it a more environmentally friendly plastic category.
Plastic products made from plastic particles are used in many fields. Plastic materials commonly used in agriculture include films, pipes, plates, ropes and woven bags. Plastic greenhouse, crop, chemical fertilizer and drug packaging are mainly used in plastic pipes, farmhouse construction, animal husbandry protection, agricultural machinery and appliances, fishing nets, aquaculture buoys and so on. As a new type of packaging material, plastic has been widely used in the field of packaging. For example, various hollow containers and injection containers (turnover boxes, containers, buckets, etc.). Packing film, woven bag, styrofoam, binding rope and packing tape. In terms of transportation, the plastic used by vehicles, trains, ships and other vehicles and corresponding auxiliary equipment increases year by year by each vehicle or ship. Types include fuel tank, bumper, sunshade seat, door handle, steering wheel, dashboard and so on.
