Carton microscopic Lead: In January 2019, the official website of the Market Supervision and Administration Department of Ningxia Hui Autonomous Region reported the results of the supervision and inspection of corrugated box products in the second half of 2018. A total of 26 batches of products were found in 12 enterprises, and the adhesive strength of the three batches was unqualified. Ningxia Municipal Supervision Bureau randomly checked 12 carton factory products, 3 products failed On January 2, 2019, the official website of the Market Supervision and Administration Department of Ningxia Hui Autonomous Region reported the results of the supervision and spot check of corrugated box products in the second half of 2018. A total of 26 batches of products were selected from 12 enterprises, and 23 batches were qualified, with a pass rate of 88.4%. The inspection basis of this corrugated box product is: GB/T6543-2008 "Single corrugated box and double corrugated box for transport packaging"; GB/T6544-2008 "corrugated board"; CCGF608.1-2015 "Quality of dangerous chemicals packaging products" Supervise and check the implementation standards and other national standards. The parameters of the flap resistance, compressive strength, burst strength, thickness, edge strength, and bond strength were tested. The results showed that the three batches of product bond strength items were unqualified. The circular pointed out that in response to the problems found in this supervision and spot check, all relevant market supervision departments shall follow the "Product Quality Law of the People's Republic of China", "Administrative Measures for Product Quality Supervision and Inspection", "Product Quality, National Supervision and Inspection, Inspection and Production of Unqualified Products" Regulations and other laws and regulations, and conscientiously do a good job of post-processing. How to improve the bond strength of the carton? The product of Ningxia Carton Factory has become the hardest hit area. In production, there are many factors affecting the bond strength of corrugated board. The quality characteristics of the binder, the quality characteristics of the base paper, the production operation technology, and the condition of the equipment all affect the bond strength of the corrugated board. The main material of the binder is starch, the fineness of the starch, and the influence of the protein on the performance of the binder. If the protein content of starch is too high, the glue will easily solidify and agglomerate to lower the viscosity; the binder with high moisture content will have a large fluidity and the viscosity will be correspondingly small; and the adhesive with low moisture content will also have fluidity. Small, the viscosity is correspondingly large; the moisture content of the base paper is too high or too low, and the water absorption of the base paper is not suitable, which will also affect the bond strength of the paperboard; the speed of the single-sided machine is too fast or too slow, and the temperature is not properly controlled. It is also easy to affect the bonding effect of the paperboard; the nip of the laminating machine is too large, and it is easy to affect the bonding strength of the paperboard; the unbalance of the single-sided machine roller will also affect the bonding strength of the paperboard; the corrugating roller and the paper guiding sheet appear. Wear and tear, the bending of the laminating machine roll and other adverse conditions will also affect the bonding strength of the cardboard. Therefore, to improve the bond strength of the paperboard, it is necessary to use good raw and auxiliary materials. According to the actual production conditions, the ratio of the adhesive should be properly adjusted, the mixing time should be controlled, and the good water quality should be used to adjust the adhesive. The binder is stirred evenly. In the production process, we must pay attention to control the appropriate amount of glue, master the relationship between the speed of single-sided machine and steam pressure, temperature and the amount of adhesive coating, and close the production process technology, maintenance, maintenance and adjustment. Production equipment, which is a reliable guarantee to improve the bonding strength of corrugated board.
