Processing principle and application of hollow glass

Insulating glass, also known as double glazing, is a highly efficient construction material used for energy conservation in buildings. It consists of two or more panes of glass separated by a spacer frame and sealed to create a dry, sealed gas space. Here's an introduction to the processing principles and application scenarios of insulating glass:

Processing Principles

1. Glass Selection: The process begins with selecting appropriate glass materials, typically clear or low-emissivity (Low-E) glass, to enhance thermal insulation and soundproofing.

2. Cleaning: To ensure a good seal, each piece of glass must be thoroughly cleaned to remove surface dust and impurities before processing.

3. Spacer Frame: A spacer frame material, such as aluminum or stainless steel, is used to separate the two panes of glass. The frame typically contains desiccant to absorb any moisture that may enter.

4. Sealing: The glass and spacer frame are bonded with a sealing agent, such as polysulfide or silicone, to create a gas-tight cavity and ensure that gases are not permeable.

5. Gas Filling: After sealing, the cavity can be filled with dry air or inert gases (such as argon or krypton) to further improve thermal insulation and soundproofing.

6. Secondary Sealing: To enhance sealing performance, a second layer of sealing agent is usually applied over the first to prevent gas leakage and moisture penetration.

Application Scenarios

1. Building Curtain Walls: Insulating glass is widely used in commercial and residential building curtain walls due to its excellent thermal insulation and soundproofing properties, especially in cold or hot regions where it can significantly reduce energy consumption.

2. Doors and Windows: Insulating glass in doors and windows can reduce heat exchange between indoors and outdoors, improving indoor comfort.

3. Conservatories and Greenhouses: Insulating glass is used in conservatories and greenhouses to reduce direct solar heat transfer while allowing ample natural light.

4. Cold Storage and Refrigeration Rooms: In places that require insulation and prevention of cold air leakage, such as cold storage and refrigeration rooms, insulating glass provides an additional layer of insulation.

5. Noise Control: Due to its excellent soundproofing characteristics, insulating glass is applied in buildings alongside highways or in noise-sensitive areas to reduce noise pollution.

6. Historical Building Preservation: In the renovation and preservation of historical buildings, insulating glass can replace original single-pane glass, improving energy efficiency without altering the building's appearance.

7. Modern Art and Design: The transparency and plasticity of insulating glass make it suitable for modern art installations and designs, such as exhibition spaces and the display of artistic works.

The processing and application of insulating glass demonstrate its importance in modern architecture. It not only enhances a building's energy efficiency but also improves the comfort and quality of life for occupants. With technological advancements and the development of new materials, the performance and application range of insulating glass are expected to expand further.
