As a whole, most of the domestic production of honeycomb paper core and composite board production equipment is derived from the vertical adhesive-bonded honeycomb paper core form of imitation He Lisheng. Only Zhejiang One Company is a horizontal adhesive adhesive paper of imitation printing equipment. Core.
The main technical parameters of the paper honeycomb core and paper honeycomb composite board production equipment at home and abroad are basically similar, but because of different customer requirements, there are differences in the height of the paper honeycomb core and the thickness of the honeycomb paperboard. The thickness of honeycomb paper core is 10-150mm domestically, the thickness of honeycomb paperboard is domestically 12-42mm, foreign is 12-152mm, and it can reach 20-50m/min both at home and abroad in cellular paper core making speed, and the production speed of the board can be the highest. Up to 15m/min. However, the foreign production lines for core making and plate making are often separated from each other by two independent production lines, operating independently, and each production line can be adjusted to its optimal production speed, while domestic manufacturing cores and plate making are integrated into one, the entire production line. The production speed is controlled by the board speed, and the best speed is only 5-8m/min.
Foreign equipment has a high degree of automation, processing accuracy and appearance are better, and the technical stability is good. In order to reduce the cost of domestic equipment, there is no comprehensive application of hydraulics, pneumatics, program control and computer automation and other high-tech, but only to achieve centralized control of the mechanized production of electrical equipment, and thus equipment processing accuracy is not high, the resulting paper core is often not equilateral hexagonal Composite board tension when the tension difference is large, and even degumming, paper utilization is low, generally about 80%, the entire production line paint, electroplating, aesthetics and other aspects are not as good as foreign products.
In terms of price, foreign equipment is much more expensive than domestic equipment. For example, the purchase of a paper honeycomb core and composite board production equipment, Israel's IMA engineering company quoted at 1.1 million US dollars (a total of 9.24 million yuan), the United States OMS company is 1.2 million US dollars (a total of 10.4 million yuan), He Lisheng company The quotation was renminbi of nearly RMB 20 million, while the domestic equipment price was between RMB 2 million and RMB 3,500,000. The price was much cheaper than that of foreign countries. Even if it was a newly developed highly automated equipment, the price was always higher than that of foreign countries. It's much cheaper.
Based on the above comparison, it can be seen that there is still a small gap between the level of domestic equipment and foreign countries. In order to rapidly improve the industrial level of China's paper honeycomb composites industry, we must first strengthen scientific research and encourage strong paperboard factories to set up scientific research institutions and improve their technological level. Secondly, strengthen alliances, expand business scale, and set up conditional companies to form group companies on a voluntary basis to achieve a combination of capital, technology, and markets; supply of raw materials, supply of accessories, manufacture of equipment, manufacture of honeycomb core paperboard, and honeycomb products In production, we will provide one-stop support, strengthen product quality inspections, standardize production according to national standards, reduce consumption, emphasize environmental protection, increase profits, and catch up with international standards. Third, to strengthen guidance, foster and develop the market, honeycomb paperboard and its products are new materials and new products. To understand and accept all walks of life, we must do a good job in propaganda, promotion and application.
Honeycomb material is a bionic material made from a honeycomb structure. At present, the production capacity of the national honeycomb paperboard is approximately 3 million square meters per year, which is widely used in the production of pallets, packing boxes and building materials.
