The advantages and safety knowledge of vegetable greenhouse insulation quilt

Vegetable greenhouse thermal insulation quilt is an energy-saving production facility. Because of its low construction cost and good thermal insulation effect, many agricultural producers have used it in production. In order to minimize the heating cost and increase the profit, how to enhance the thermal insulation capacity of the greenhouse and reduce the heat loss has almost become the concern of many greenhouse users. The thermal insulation performance of a solar greenhouse is a comprehensive result of many factors. In addition to rationally determining the size of the greenhouse structure and construction materials, it is also critical to select appropriate thermal insulation quilt materials and plastic films. The greenhouse insulation is laid on the front slope of the greenhouse, and is mainly used for the nighttime insulation of the greenhouse, so it is a requirement for the insulation quilt to have good insulation performance. Secondly, the greenhouse insulation is required to be rolled up after sunrise and put down before sunset, so the corresponding insulation system is also a movable quilt system, so the thermal insulation quilt material is required to be a flexible material. Third, the solar greenhouse will always work in the outdoor open air after it is installed. For this reason, it is required to be windproof, waterproof, and anti-aging to adapt to the daily wind, rain, snow, hail and other natural climatic conditions. Finally, the solar greenhouse insulation quilt should also have a wide range of material sources, low manufacturing and processing costs and market prices. Vegetable greenhouse insulation and fire protection: 1. It is necessary to develop good daily fire prevention habits, return flammable firewood to the area, and prevent the formation of large-scale fires. 2. Try to improve the fire resistance level of rural greenhouses, and use non-combustible and flame-retardant materials to build them. At the same time, more flame retardants can be prepared next to the greenhouse, and the buildings of the fire passage can be used to ensure fire separation. 3. Since there will be flammable materials near the greenhouse, it is forbidden to use open fire near the greenhouse, especially in dry winter, to prevent the greenhouse fire caused by burning straw at will. 4. Generally do not use high-power electrical appliances in the greenhouse. If lighting is really needed, the bulb used should not be higher than 60W, and the bulb should be kept at least 60cm away from the ceiling. Regularly replace outdated and aging electrical lines, strictly abide by the electrical operation specifications, and resolutely put an end to the phenomenon of random wiring in the greenhouse. 5. When building a stove in the greenhouse for heating, flame retardant protection should be done around the furnace barrel, and a fireproof cap must be installed on the furnace barrel to prevent flying fire from igniting the greenhouse. When dumping the ash, make sure that there is no spark before pouring it out, so as to prevent sparks from igniting the greenhouse. The advantages of vegetable greenhouse insulation quilt: 1. Good insulation performance: cover the surface of the greenhouse, keep the heat in the greenhouse, reduce the heat loss, increase the temperature of the greenhouse by 3-5 degrees, and the insulation effect is continuous; 2. Light weight: new type of insulation The quilt is made of all the materials used. Compared with the traditional thermal insulation quilt, it has the advantages of small size, light weight and easy storage. During the 4 years, during the non-stop retracting and retracting period of the rolling shutter machine, the straw mat is easy to disperse with one foot, which increases the cost of the enterprise. The new type of insulation is made of non-woven fabrics, and the joints are densely connected, which can withstand relatively strong tension and pressure. The service life is between 20-30 years, and the service life is very ideal; 4. Easy to clean: the outer layer of the thermal insulation quilt is made of non-woven fabric, which is sewn and has its own self-cleaning ability, which can prevent dust and magazines from entering the inner layer , and does not affect the light transmission intensity, the photosynthetic production of crops, and the yield; 5. It is not easy to poke the greenhouse: After the traditional straw mat is woven, burrs will occur during the use process, and it is easy to puncture in the process of retracting and laying. Greenhouse plastic, and the new non-woven thermal insulation quilt has a smooth surface and soft texture, which will not damage the greenhouse film. 6. In acid and alkali environment, the strong insulation is made of chemical fiber and chemical fiber, and the surface layer is treated with professional anti-radiation treatment. The corrosion degree is light and slow in specific acid and alkali environments, so it can be carried out for a long time. Preserved, not spoiled. 7. The cost is relatively low The traditional grass mat is retracted and placed by manholes, and it is damaged and has a short service life, so the cost is increased to a certain extent.
