It is recommended that the length of the extension should not exceed 5 meters. Among all the sunshade products, the canopy is a good partner for the sunroom. Outside sunshade electric double-track ceiling curtain: electric double-rail folding ceiling curtain is a sunshade system that can be retracted and put on the top or oblique side glass window frame of indoor lighting roof, that is, double-rail translation system. If the daylighting of the balcony at home is on the middle side, it is recommended not to use full shading curtains, but to use semi-shading curtains, so it is appropriate to choose whether shading is needed or not. The color of the space tends to be simple and pure. Plus the silver-gray sunshade looks like a perfect match.
At present, the most popular sunshade component material is metal. Lightweight aluminum can be processed into sunshade grille, sunshade shutter, sunshade blinds and so on. These sunshade products are produced by computer control, and the finished products are exquisite. Coupled with “high technology” to ensure the accuracy and precision of metal sunshade components. If the use of high-performance thermal insulation and thermal reflection glass made of glass sunshade, combined with photoelectric photothermal conversion sunshade, will make sunshade materials and technology, please climb to another high-rise building.
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.
It is precisely because of this application advantage that the products of agricultural film manufacturers will be recognized by consumers and are widely used in agricultural planting, and its application effect is still very good. Users from all walks of life are sincerely welcome to visit us. 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.
The construction of glass greenhouse has always been a concern of crop planting places, multi-span greenhouse breeding greenhouse, border surface poured with bottom water before sowing. Gently rake the topsoil with a tooth rake to sow the seeds into the soil, cover the border with a layer of plant ash, and cover the sunshade net with straw or a small arch shed after sowing in summer and autumn to prevent erosion by high temperature and torrential rain. Keep the soil warm and moist for 6-7 days, and the winter sowing temperature is on the low side, then cover the border with plastic film or sunshade net to promote seedling emergence, remove the seedlings after emergence, and make the circular movement into a linear movement. the aluminum drive card connected to the drive wire drives the edge aluminum profile to move parallel on the cord through cross-connection, driving the edge aluminum profile to pull up one end of the curtain cloth and slowly unfold and close. That is, all aluminum drive cards turn off the limiter switch after closing. When the motor stops working and the operation ends, the facade side roll sunshade insulation system forms a complete sealed space composed of sunshade and thermal insulation curtains in the solar greenhouse.
