Precautions for the use of greenhouse insulation in spring and the harm of water in the insulation layer

With the continuous development of greenhouse vegetable planting industry, greenhouse thermal insulation quilts have also been developed by leaps and bounds. Greenhouse thermal insulation has been applied in many places, and thermal insulation quilts can be seen in industry, agriculture, construction and other industries, but greenhouse thermal insulation The main application is agriculture. Spring is a windy and rainy season, and I have provided farmers with some precautions for using greenhouse insulation quilts in spring. The nylon rope at the bottom is fixed on the mechanical iron rod of the greenhouse, and the upper end is fixed on the steel wire. If there is a deviation during use, the insulation should be adjusted in time to ensure that the insulation is fully covered on the greenhouse. After the thermal insulation is covered on the top of the greenhouse, a connecting rope is used to connect the thermal insulation lap joints into one. 2. The greenhouse insulation quilt is on the back wall of the greenhouse, and should be fixed on the top of the wall, so that the top of the wall has a certain slope to the north, and needs to be covered with a complete tarpaulin, which is conducive to the discharge of rainwater and prevents The rain soaked the quilt. 3. When the thermal insulation quilt covers the bottom of the greenhouse, water should be accumulated on the ground in time to prevent rainwater from soaking the thermal insulation quilt. Qualified farmers should place old straw curtains at the junction of the ground and the greenhouse film to prevent the greenhouse insulation from being exposed to the ground and damp. 4. After the insulation is covered, the east and west walls of the greenhouse should be pressed 30CM, and pressed with sandbags to prevent them from being blown up by strong winds and reduce the insulation effect of the greenhouse. The insulation layer of the greenhouse insulation quilt is very harmful to water. If you do not pay attention to the use of greenhouse insulation, there will be many problems. For example, if the insulation layer gets water, it is easy to cause the insulation material to rot inside. If there is rot, the thermal insulation effect will be greatly reduced. Therefore, it is necessary to pay attention to such matters when using greenhouse insulation quilts. It is closed with rolling shutter, and the plastic film is fixed on the surface to form a plastic arch shed. When it is subjected to external load, the shape or size will change. Compared with other thermal insulation materials, it is multifunctional. Rapid decay and deterioration of insulation materials and winter junction cover temperatures can increase. The greenhouse insulation is stored on the back wall or transported to the home to be sealed with a waterproof membrane. It is required that the thermal resistance of the insulation material covered at night on the front slope of the greenhouse should reach the total thermal resistance of the wall, which will cause indefinite damage to the greenhouse, regardless of stretching. Strength can be obtained by testing or compression testing.
