Sandwich panel is a common decoration material in the decoration at present. What is sandwich panel? What are the characteristics? Now I'll explain this kind of problem to you. I hope you can gain something:
It is composed of two-layer formed metal panel and polymer insulation core foamed and matured directly in the middle of the panel, which is easy to install, light and efficient. The filling system also uses a closed bubble molecular structure, which can prevent condensation of water vapor. Sandwich panel is a common product in current building materials, which can not only provide good flame retardant and sound insulation, but also protect the environment. At present, the classification of sandwich panels includes: polystyrene sandwich panels, namely EPS sandwich panels; Extruded polystyrene sandwich panel, namely XPS sandwich panel; Rigid polyurethane sandwich panel, i.e. Pu sandwich panel; Three polyester sandwich panels, namely PIR sandwich panels; Phenolic sandwich panel, namely pf sandwich panel; Rock wool sandwich panel is RW sandwich panel.
What are the characteristics of sandwich panel
1. Light weight: the weight of the sandwich panel per square meter is less than 24kg, which can fully reduce the structural cost.
2. Strong plasticity: the sandwich panel can be cut at will to meet the needs of special design.
3. Environmental protection and noise prevention: the sound insulation strength of sandwich panels can reach 40-50 dB. Sandwich panels are very effective sound insulation materials.
4. Fire prevention: the surface materials and thermal insulation materials of sandwich panels are non combustible or non combustible materials, which can meet the requirements of fire prevention specifications.
5. Beautiful: the clear lines of sandwich panels have dozens of colors, which can meet the needs of any style of buildings
6. Fast installation: the characteristics of light weight, plug-in, installation and free cutting of sandwich panel determine its easy installation, improve relevant benefits and save construction period.
7. Fire resistance: the sandwich panel treated with special coating can last for 10-15 years. After that, anti-corrosion coating will be sprayed every ten years, and the service life of the panel can reach more than 35 years.
8. Thermal insulation: common thermal insulation materials include rock wool, glass fiber wool, polystyrene, polyurethane, etc., which have low thermal conductivity and good thermal insulation effect.
9. High strength: it uses high-strength steel plate as the base material, with a tensile strength of 5600 (kg / cm2), coupled with very advanced design and roll forming, which has very good structural characteristics.
