Although the solar greenhouse has a very good thermal insulation performance, but from the point of view of safety, heating equipment is still an important factor. The southern part of our country generally does not need to heat up, but if we encounter bad weather continuously, we still need to use the energy stored in the greenhouse itself, otherwise it will not be able to meet the growth of vegetables. Therefore, whether in the south or north, heating equipment has always been a necessary protective measure. The technical aspect requires that in the equipment configuration of solar greenhouse, the configuration of thermal insulation equipment should be demonstrated in great detail. Of course, the work of Hunan Ecological Restaurant needs the cooperation of a variety of equipment, with higher and higher temperature requirements, especially in autumn and winter production, external sunshade system, internal thermal insulation system and window opener and fan, wet curtain and other equipment need to be applied. For more information about Hunan Ecological Restaurant Project, please contact Minghao greenhouse Engineering Construction Company directly.
Camry has the advantages of atmospheric appearance and humanized functions, such as various controls on the steering wheel and constant speed cruising, electric seats and sound effects are more satisfactory, the dashboard has a faint blue atmosphere feels good, at the same time, the sunshade is very practical to improve the grade, headlamp cleaning is also more practical, excellent acceleration performance, fuel consumption can also be
The technical proposal adopted by the utility model for solving its technical problems is that a sunshade picnic heat preservation package comprises a package body, the top of the package body is provided with a circle opening and a cover connected with the opening through a zipper, two symmetrical straps are arranged on both sides of the package body, and an integrated plastic skeleton is arranged on the side wall and the bottom of the package body. The plastic skeleton comprises a chassis matched with the bottom of the inclusion body and a support bar supporting the four corners of the inclusion body vertically around the chassis. The inner wall of the inclusion body is provided with an aluminum film thermal insulation lining layer, which can be used for high temperature heat preservation and low temperature heat preservation, and the effect is good. One corner of the inclusion body is provided with a cylindrical groove arranged in the inclusion body, the bottom of the groove is provided with a base, and the base is provided with a retractable umbrella handle. The retractable umbrella handle is provided with a sunshade, which can be used as an umbrella when the sun is strong or it rains.
It can reduce the harm of cold current, when the temperature in the shed is below ℃ for a long time. Mulch such as straw bag non-woven sunshade net should be covered in the greenhouse at night to prevent frost damage and adopt pot fire or furnace fire to temporarily heat up. Open fire should not be used when heating to prevent smoke damage, and a flue should be set up to keep harmful gases outdoors, focusing on the heat preservation and anti-freezing of vegetables and seedlings in the greenhouse. For eggplant seedlings which are in the early stage of raising seedlings, measures such as artificial light supplement and temperature increase can be taken to prevent freezing injury or excessive growth of seedlings; in cloudy and rainy days, the mulch should be properly removed.
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 ℃ ~ 10 ℃. 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.
Foshan Chenghang plastic Technology Co., Ltd. for you a detailed interpretation of UOJWGl Sanshui District outdoor plastic balcony sunshade board production related knowledge and details, sunlight board set lighting, heat preservation, sound insulation in one, can be sunshade and rain, but also heat preservation and light transmission, can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. In foreign countries, in addition to supporting the structure, the pure polycarbonate material quantity of large-scale bright lighting house, a sunshine, crystal transparent, warm and annoying.
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.
