Vacuum Insulation Panel Lamination for Mechanical Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum Insulated Panels (VIPs) are sensitive to mechanical stress and have limited fastening and adhesive properties, restricting their use in construction applications due to the vulnerability of the gas-tight film and difficulty in handling.
Innovation Solution
A multilayered body is created by laminating a primer layer based on acrylic copolymers with ground limestone onto the VIP, followed by a jacketed plasterboard, which provides a protective layer and improved adhesion, allowing for better mechanical protection and versatile handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a gas-tight film is used to enclose the core material in a VIP, then thermal insulation performance is improved through vacuum effect, but mechanical strength and resistance to damage is worsened
Solution Approach 1:
The patent applies composite materials by combining the gas-tight film with a plasterboard layer to create a multilayered structure. The plasterboard provides mechanical strength and protection while the gas-tight film maintains the vacuum for thermal insulation, thus resolving the contradiction between thermal performance and mechanical strength.
Solution Approach 2:
The plasterboard layer serves as a protective cushion that absorbs mechanical stress and protects the gas-tight film from damage before the stress can reach the vulnerable film. This beforehand protection allows the VIP to maintain both thermal insulation performance and mechanical resistance.
2Loss of energy
If a gas-tight film is used to enclose the core material in a VIP, then thermal insulation performance is improved through vacuum effect, but ease of operation and handling is worsened due to sensitivity to mechanical effects
Solution Approach 1:
By creating a composite structure with plasterboard, the VIP becomes more robust and easier to handle during installation and processing. The plasterboard provides a sturdy surface that resists mechanical effects while the internal vacuum structure maintains thermal insulation performance.
Solution Approach 2:
The plasterboard layer provides beforehand protection against mechanical effects during handling and installation, reducing the sensitivity of the gas-tight film to damage and improving overall ease of operation.
3Loss of energy
If a gas-tight film is used to enclose the core material in a VIP, then thermal insulation performance is improved through vacuum effect, but adhesive properties and fastening possibilities are worsened
Solution Approach 1:
The plasterboard layer provides a suitable surface for adhesive application and fastening operations, enabling versatile installation methods while the gas-tight film maintains the vacuum for thermal insulation. This composite approach resolves the contradiction between thermal performance and adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the mechanical robustness and adhesive properties of VIPs, enabling their use in high-stress areas and expanding their application in construction by providing a protective layer that must be penetrated before the gas-tight film is damaged, and allowing for the application of typical construction materials.
Implementation Method 1
the physical principle of vacuum insulation using the above-described thermal insulation body is equivalent to that of a vacuum flask: thermal transport cannot take place via the movement of air (convection) in a space empty of air
Implementation Method 2
Evacuated thermal insulation bodies have become known in the field of thermal insulation technology
Implementation Method 3
the primer layer is based on a dispersion of acrylic copolymers with ground limestone, wherein the laminated-on lamination layer is an external component of a jacketed plasterboard
