Generally, glue is not used inside plastic honeycomb panels, but it is required in certain circumstances.
1. What is plastic honeycomb panel?
Plastic honeycomb panel is a lightweight and high-strength material with a structure similar to that of a honeycomb. It is composed of many small round honeycomb units and has good sound absorption, heat insulation, sound insulation and compressive strength.
2. Material structure of honeycomb panels
The outer layer of PP honeycomb panel is usually a non-woven surface layer, and the raw material itself is also PP. This layer of fabric is convenient for different customers to combine suitable surface materials. The internal filling is polypropylene PP round-hole honeycomb structure.
3. The use of glue for honeycomb panels
Typically, no glue is used inside honeycomb panels. In the manufacturing process of honeycomb panels, in order to ensure the maximum sound insulation, heat insulation, sound absorption, compressive strength and other properties of honeycomb panels, the use of glue will affect the integrity and mechanical properties of the honeycomb structure. The plastic itself can be hot-melted Tight connection, and no glue is required. However, in some special cases, if it is necessary to increase the strength of the honeycomb panel, or to reinforce the interface of the honeycomb panel, or to combine other panels, professional industrial glue can be used for bonding.
4. Application areas and advantages of honeycomb panels
Honeycomb panels are widely used in aerospace, shipbuilding, high-speed rail, construction, automobiles, electronic appliances and other fields. Due to its lightweight and high-strength characteristics, honeycomb panels can be used in the manufacture of shipbuilding, aircraft, high-speed rail, automobiles and other transportation vehicles, and can also be used in building sound insulation, doors, windows, ceilings, walls and other fields.
Therefore, under normal circumstances, honeycomb panels do not need to use glue, but in some special cases, professional industrial glue needs to be used to strengthen its strength and interfaces or cladding layers.
