Technical Field

The invention relates to the technical field of vacuum glass, in particular to a glass component and a glass greenhouse.

Background

At present, most of agricultural greenhouses in China are low-end film/wood greenhouses, and with the development of the society in China and the progress of the technology, the construction of glass greenhouses is more and more extensive. Glass is used as a main body of a ceiling and side walls of the glass agricultural greenhouse, but the heat transfer coefficient of common glass is high, and the energy consumption is huge when the glass agricultural greenhouse is required to maintain a constant temperature.

The vacuum glass can greatly reduce the heat conduction of the glass, thereby effectively reducing the energy consumption of the greenhouse. However, in the conventional vacuum glass, most of the existing manufacturing methods of vacuum glass are to support and isolate two layers of flat glass, seal the periphery of the flat glass to form a cavity, and obtain a vacuum cavity through the steps of sintering, vacuumizing, sealing and the like. The sealing material of the vacuum glass mainly comprises an organic material, a metal soldering lug and low-melting-point glass, wherein the organic material and the metal soldering mode can greatly influence the performance and the service life of the existing vacuum glass, and the requirement on the twenty-year durability of the glass agricultural greenhouse material can not be effectively met.
