A brief introduction to the repair method of vegetable greenhouse insulation quilt

If there is a damaged method in the process of using the vegetable greenhouse insulation quilt, you must know how to repair it, so as to ensure the insulation effect and service life of the vegetable greenhouse insulation quilt. 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 nighttime insulation of the greenhouse, so good insulation performance is the main requirement for the insulation quilt. Secondly, the greenhouse thermal insulation is required to be rolled up after sunrise and put down before sunset, so the corresponding thermal insulation system is also a movable roll quilt system. Therefore, the thermal insulation quilt material is required to be a flexible material. Thermal insulation quilt is a high-speed and 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 improve the speed, how to enhance the thermal insulation capacity of the greenhouse and reduce the heat loss has almost become the concern of many greenhouse users. Now there is a vegetable greenhouse thermal insulation quilt with pearl cotton as the cotton core on the market. This thermal insulation quilt is a little light, and the thermal insulation effect is greatly improved. The main thing is that the pearl cotton has such a strong waterproof property. However, the disadvantage of this kind of insulation quilt is that the production process is complicated, the production cost is high, and the transportation cost is also very high. Now it has not completed the market dominance. However, with the more refined demand for greenhouse crops in the future, this kind of insulation is believed to be possible. Interpret the future representative of the future vegetable greenhouse insulation quilt. There are many factors that affect the insulation of winter warm greenhouses. However, just in terms of thermal insulation quilts, the thermal insulation effect is good or bad. An excellent vegetable greenhouse insulation quilt should start with the quilt surface and cotton core. There is no woven fabric for general use on the market now, and this kind of insulation is durable. long life. The cotton core is selected as much as possible in the mixed cotton core. Good thermal insulation effect. However, pearl cotton has appeared in recent years. This cotton core is indeed waterproof. But the cost will increase. It has not been widely used yet. Briefly introduce the method of repairing the insulation of vegetable greenhouses: 1. Short-term temporary paper repair method: The insulation of vegetable greenhouses is slightly damaged. After dipping a piece of paper in water, it is attached to the damaged place while it is wet. This repair method is only used for temporary remedies. It can only be closed for ten days and a half months, not for a long time. If you are busy with farming, you can't take care of it, and it can temporarily play an excessive role in repairing it in the future. 2. Water replenishment method: Scrub the damaged greenhouse insulation quilt, cut a piece of film that is slightly larger than the damaged area and have no holes, dip it in water and stick it on the hole, drain the air between the two films, and press it evenly. Can. 3. White batter and brown sugar filling method: use white flour and water to make a batter, and then add red glutinous rice equivalent to 1/3 of the weight of dry flour. After a little heating, it can be used to fill the film. 4. Glue repair method: This method is somewhat similar to the second method. Clean around the hole and apply it with a brush dipped in special glue. After 3-5 minutes, take a film of the same texture and stick it on it, and the glue dries. Then stick it firmly. In the process of using the vegetable greenhouse insulation quilt, there is at least about ten centimeters of overlap at the junction of each quilt. This effectively controls the external convection of the temperature. When the insulation is put down, there should be at least ten centimeters of clearance from the ground. Prevent the temperature in the greenhouse from escaping through the bottom of the greenhouse. There is also a hot-fix method that is more labor-intensive, that is, clean up the damaged area of ​​the vegetable greenhouse insulation, clean cotton, and then attach it with non-woven cloth, etc., and stitch it again. In short, we need to regularly check the insulation of the vegetable greenhouse, and repair it immediately if it is damaged. Otherwise, if it rains on a cloudy day, the rainwater will enter the quilt along the damage, which will wet the entire quilt and damage the entire vegetable greenhouse. Insulation quilt. Vegetable greenhouse insulation is widely used as a major invention in modern greenhouse agriculture. Corresponding quilt factories mainly based on vegetable greenhouse insulation have been born one after another. Demand is also escalating and becoming more and more rational. Rather than simply being price-driven as it was a few years ago. And pay more attention to thermal insulation effect and service life. It can be said that vegetable greenhouse insulation has moved towards the high-tech of modern agriculture. Whether it is from the fabric and cotton core, or from the production process and production process, there are all different needs and requirements than before.
