Honeycomb paper is made according to the principle of natural honeycomb structure. It is made by corrugating the corrugated paper into a myriad of hollow three-dimensional regular hexagons to form a whole force-bearing piece, the paper core, and the bonding surface on both sides. A new type of sandwich structure environmentally friendly energy-saving material made of paper. In recent years, many wooden doors have used honeycomb paper as the inner panel of the door. First, the term explains honeycomb paper Honeycomb paper is made according to the principle of honeycomb structure in nature. The corrugated paper is bonded into numerous hollow three-dimensional regular hexagons by adhesive bonding method to form a whole force-bearing piece, the paper core, and the paper is bonded on both sides. A new type of sandwich structure for environmentally friendly energy-saving materials. Second, the advantages and disadvantages of the three major advantages First, it is light and low cost. Compared with other various sheet metal structures, the honeycomb sandwich structure is very light and has the highest strength-to-mass ratio, so that the finished product has a good performance price ratio. Reducing the use of wood is in line with the trend of environmental protection. Second, it is not easy to deform and has good shock absorption performance. The honeycomb sandwich structure has good stability and is not easily deformed, and its outstanding pressure resistance and bending resistance are the most important characteristics required for the box packaging material. Because there are many dense honeycombs that are mutually restrained, like many small I-beams, they can be dispersed and bear the pressure from all parties, so they also have strong earthquake resistance. Third, sound insulation and heat insulation performance are good. In the honeycomb core of the commonly used honeycomb sandwich panel, the volume of the solid material is only 1% to 3%, and the remaining space is the air in the closed state. Since the sound insulation and heat insulation performance of the air is superior to that of the solid material, the thermal energy and the sound wave are greatly limited, so the honeycomb sandwich panel has good heat insulation and sound insulation properties. Third, the two disadvantages of honeycomb paper doors First, the life is short. Honeycomb paper door has low cost, low added value of materials and relatively short service life. It is suitable for use as substrate and furniture parts of sheet metal, and is not suitable as the main door of the family. The second is the bearing capacity difference. The load-bearing capacity of the honeycomb panel door is generally not more than 30 kg. In general, honeycomb panels are relatively weak in solidity and are not as durable as solid wood doors made from traditional materials.
