Method for prolonging service life of solar greenhouse heat preservation quilt

Abstract

The invention relates to a greenhouse heat preservation device and in particular relates to a method for prolonging the service life of a solar greenhouse heat preservation quilt. An ultraviolet barrier layer (2) is paved between the heat preservation quilt (1) and a greenhouse coverage material (3); the ultraviolet barrier layer (2) can be rolled up together with the heat preservation quilt (1) when the heat preservation quilt (1) is rolled up; the width of the ultraviolet barrier layer (2) at least ensures that the ultraviolet barrier layer (2) can completely cover all exposed parts of the heat preservation quilt (1) when the heat preservation quilt (1) is totally rolled up. Due to the ultraviolet barrier layer (2), thermal ageing and light aging of the heat preservation quilt (1) are alleviated, so that the service life of the heat preservation quilt can be greatly prolonged; by the method, the service life of the heat preservation quilt can be greatly prolonged at low cost.

Description

technical field [0001] The invention relates to a greenhouse heat preservation device, in particular to a method for prolonging the service life of a solar greenhouse heat preservation quilt. Background technique [0002] Covering plastic transparent materials are widely used in production facilities in winter protected areas such as solar greenhouses and greenhouses. The nature of the material itself determines the high infrared transmittance, and heat preservation is one of the most important technical measures for the winter production of the northern solar greenhouse. For a long time, the heat preservation of the front roof of the solar greenhouse at night mainly depends on covering grass thatch. Traditional thermal insulation covering materials such as straw thatch and cattail mats have good thermal insulation effects, many sources of materials, and easy processing, and have played a pivotal role in the development of solar greenhouses. However, with the intensive and...

AI Technical Summary

Problems solved by technology

Although it is mentioned in many literatures that the fabrics of thermal insulation quilts are anti-aging, it is found in actual use that the service life of many thermal insulation quilts is only about one year, and the better ones can only reach 3-4 years, especially in Shorter lifespan at high altitudes
