Manufacturing process and thermal insulation performance characteristics of greenhouse thermal insulation quilt1

The greenhouse insulation quilt is to be beautiful, flat and easy to roll. The thermal insulation quilt is made soft because it can be attached to the uneven plastic sheet, and it is not easy to enter the wind, which can really make the thermal insulation quilt play a role in thermal insulation. The greenhouse thermal insulation quilt is made with a throw degree because it conforms to the thermal insulation principle of the greenhouse thermal insulation quilt. This is the reason why ten layers of single layer are not as good as one layer of cotton. The production method of the greenhouse thermal insulation quilt: In order to make the thermal insulation quilt soft, polished, flat, strong and durable, it is necessary to lay the produced felt first, and then go through a special flower extension machine on the felt. A thick layer of wool, and then a layer of felt on top, plus a layer of plastic cloth, Oxford cloth on the top and bottom (the front is rainproof, the back is not rainproof), and then It is made by sewing 14 threads with a special machine. In order to prolong the service life of the thermal insulation quilt, it is necessary to pay attention to the use of the thermal insulation quilt: when using the thermal insulation quilt, the overlap between the two beds should not be less than 10cm. The greenhouse insulation quilt should pay attention to prevent it from being infiltrated when it rains at the top of the back wall of the greenhouse; after the insulation is covered, the things on the walls of the shed should be fixed well, and the surrounding areas should be pressed tightly to prevent it from being blown by the wind and reducing the effect of thermal insulation. The commonly used thermal insulation quilts and greenhouse thermal insulation quilts are of various materials and specifications, and the scope of application mainly includes vegetable greenhouses, herb greenhouses, breeding greenhouses, and gradually extended to long-distance transportation coverage. The performance of thermal insulation quilt products is gradually improved, and there are many advantages: 1. Good thermal insulation performance: It is covered on the greenhouse thermal insulation quilt film to keep the temperature in the shed unchanged, reduce the heat loss rate, and ensure that the temperature in the greenhouse can be higher than the outdoor temperature for a long time 3 ~5 degrees. 2. Light weight: The new type of thermal insulation quilt is made of all materials. Compared with the traditional thermal insulation quilt, it has the characteristics of small size, light weight and easy storage. 3. Long service life: Generally, the service life of straw mats will not exceed four years. The rolling shutter machine is used for daily retraction work. The straw mats are easy to be scattered and the production cost will increase. The thermal insulation quilt is made of non-woven fabric, the interface connection is tight and not easy to be damaged, can withstand strong pressure and tension, and has a service life of 20 to 30 years. Fourth, easy to clean: The outer layer of the thermal insulation quilt is designed with non-woven fabrics, which can prevent the entry of dust and magazines, and its own cleaning ability will not affect the light transmission intensity at all, and the photosynthesis of crops will proceed normally. Increase production.
