Introduction
CCP thermal insulation composite board, also known as honeycomb composite sandwich panel, is a new type of sandwich material designed to satisfy the requirements of good thermal insulation and high strength. It is widely used in refrigeration, automotive and building curtain walls. Its high thermal insulation properties, light weight and simple installation process make it popular in many fields.
Principle of Heat Insulation of Composite Board
The principle of heat insulation of the composite board can be divided into two parts. One is the thermal insulation effect of the honeycomb core material and the other is the heat insulation effect of the duvet. The honeycomb core material is made of a large number of hexagonal holes, which are carefully designed to have small widths and large surrounding area, which are beneficial to prevent heat transfer. And this effect is enhanced by the low thermal conductivity of the material itself. The duvets are made of materials with superior heat insulation performance and low thermal conductivity.
Main Material of CCP Heat Insulation Composite Board
The main materials of the composite board include metal sheet, polymer sheet and honeycomb core material. For metal sheet, the thickness and type of sheet are mainly determined according to the actual needs. Commonly used material includes cold rolled sheet and hot rolled sheet. The surface of metal sheet needs to be pretreated to prevent corrosion. According to the application/usage of honeycomb composite sandwich panel, the polymer sheet also has a wide range of material that can be selected. Its common materials include ABS and PE. The honeycomb core material is usually selected from paper honeycomb, aluminum honeycomb and honeycomb cardboard.
Manufacturing Process of CCP Heat Insulation Composite Board
The manufacturing process of honeycomb composite sandwich panel involves three processes: material cutting, hot pressing and edge milling.
1. Material cutting: cut metal sheet and polymer sheet according to the size of the finished panel.
2. Hot pressing: place the honeycomb core material between two metal sheets and two polymer sheets, and then use corresponding equipment to heat and press them together to form a panel.
3. Edge milling: use edge milling machine to process the panel edges.
Advantages of CCP Heat Insulation Composite Board
The CCP hot insulation composite board has the following advantages:
1. Light weight: the weight of the sandwich panel is only 40-50% of that of a conventional sandwich panel of the same size, which greatly reduces the load of the building structure.
2. Good thermal insulation properties: honeycomb core materials are used to reduce heat transfer and the duvet materials can effectively improve the ability to resist heat transfer.
3. High earthquake resistance: the combination of honeycomb core and duvet can effectively reduce the vibration caused by the earthquake and greatly improve the resilience of the building structure.
Conclusion
Honeycomb composite sandwich panels have a strong ability to resist heat transfer, good thermal insulation performance and light weight. In addition, the composite panel has high seismic resistance, which makes it widely used in the automotive and building curtain walls. In summary, the production of CCP thermal insulation composite board is a very promising development.
