The development of honeycomb paperboard structure is difficult

      The development technology of honeycomb paperboard in China began in the 1980s. After more than ten years of efforts, China’s honeycomb paperboard technology has made a breakthrough. Overview Of Common Faults In PS Version

     However, although the development prospect of honeycomb paperboard in China is promising, the problem can not be ignored. Overview Of Common Faults In PS Version

        There is still a big gap between the development of honeycomb paperboard and corrugated paperboard. At present, the main problems restricting the development of honeycomb paperboard are as follows: 

      first, there is still a big gap between China’s honeycomb paperboard production line and foreign advanced level in terms of integrity, stability, processing accuracy and appearance quality. Overview Of Common Faults In PS Version

       The degree of automation of production equipment is low, and some processes are still operated manually, resulting in low production efficiency. In particular, the molding and processing equipment for honeycomb paperboard products is relatively simple, and some are even blank.Overview Of Common Faults In PS Version

        The processing level of molding technology is an important link to ensure the quality of paper honeycomb products. The molding process of honeycomb paperboard and corrugated paperboard is different. The former has high requirements and great difficulty. The processes such as indentation, die cutting, slotting, edge banding, bonding, ell, – 0 and box ordering of corrugated board can be solved on mechanical equipment.Overview Of Common Faults In PS Version

          However, there are still problems in the product forming process of honeycomb paperboard, such as indentation, edge banding, moisture resistance, flatness and smoothness. The surface of honeycomb paperboard products is rough, the color is poor and the grade is not enough, It is difficult to achieve standardization and serialization and meet the needs of users. Overview Of Common Faults In PS Version

      Therefore, honeycomb paperboard molding technology is still an important factor to suppress the development of honeycomb paperboard.Overview Of Common Faults In PS Version

         In addition, the waterproof and moisture-proof problems of honeycomb paperboard have not been well solved. The strength of the packing box and tray made of honeycomb paperboard is weakened after being affected with moisture and can not withstand impact and vibration. Overview Of Common Faults In PS Version

      In the ability to resist the invasion of foreign objects, corrugated paperboard is several times higher than honeycomb paperboard. Moreover, honeycomb paperboard is difficult to box, and there is no suitable supporting equipment, so it is difficult to produce cartons on a large scale.

        Second, market problems. At present, the market of honeycomb paperboard is still vague. The first thing that affects the market development is the price. In fact, the price of honeycomb paperboard is not much cheaper than that of wooden packaging; The market is also affected by the effect of replacing wood. Overview Of Common Faults In PS Version

      Honeycomb paperboard is mainly used for pallets and cushion pads, but the technical problems such as waterproof and moisture-proof have not been well solved, which affects the use effect.Overview Of Common Faults In PS Version

       Third, poor sense of operation and service. Some paper honeycomb enterprises are eager for quick success and instant benefit, short-sighted and low management level. Overview Of Common Faults In PS Version

     They not only do not pay attention to product quality, exaggerate hype and shoddy, but also do not pay attention to after-sales service, and can not provide customers with technical and technological support in time, resulting in adverse effects.Overview Of Common Faults In PS Version

Performance comparison between corrugated board and honeycomb board

      The corrugated board and honeycomb board with the same face paper and core paper, the same amount of paper and the same adhesive between the core layer and face paper are tested for performance. The test data are shown in Table 1.Overview Of Common Faults In PS Version

Standardization specified by data:Overview Of Common Faults In PS Version

(1) The flat pressing strength of honeycomb paperboard is much higher than that of corrugated paperboard, and when the amount of consumables is certain, the flat pressing strength of honeycomb paperboard decreases with the increase of pore size.

(2) The lateral compressive strength of honeycomb paperboard decreases with the increase of pore size; The lateral compressive strength of corrugated board is much higher than that of honeycomb board, while the lateral compressive strength is lower than that of honeycomb board.

(3) The bending strength of honeycomb paperboard is higher than that of corrugated paperboard, and its bending strength increases with the increase of pore size.Overview Of Common Faults In PS Version

(4) The peel strength of corrugated board is higher than that of honeycomb board; The peel strength of honeycomb paperboard increases with the decrease of pore size.Overview Of Common Faults In PS Version

(5) There is no big difference in the puncture strength between honeycomb paperboard and corrugated paperboard.Overview Of Common Faults In PS Version

      From the above analysis, it can be seen that the development of corrugated board and honeycomb board has reached its limit and the other is difficult, so we must develop a new world.Overview Of Common Faults In PS Version

       If corrugated paperboard and honeycomb paperboard are combined, the advantages of corrugated paperboard and honeycomb paperboard can be brought into play, and the side compressive strength and flat compressive strength of its composite paperboard can be improved. 

       In addition, when making the packing box, if the corrugated box is used as the box, and the upper and lower walls of the box are padded with honeycomb paperboard, the shockproof, compression resistance, thermal insulation, puncture resistance and bearing capacity of the packing box can be improved. 

      Therefore, at this stage, corrugated board and honeycomb board can not become competitors to each other, but should become partners in production and application.Overview Of Common Faults In PS Version

        Corrugated board and honeycomb board have their own advantages. To sum up, the advantages of corrugated board are: strong strength, mature products and strong talents, but the enterprise has excess production and urgently needs to develop a new market. The advantages of honeycomb paperboard are: Overview Of Common Faults In PS Version

      large market, new products and good benefits, but the enterprise scale is small, the development is not fast and there are many difficulties. I hope to get strong support from the corrugated paperboard industry. Overview Of Common Faults In PS Version

       Therefore, the two should be combined, complementary advantages and common development, which is the inevitable trend of scientific development.Overview Of Common Faults In PS Version
