The deformation and cracking of tape paper tubes during use will affect their normal use and the winding quality of the tape. The following are some effective preventive measures.
First, ensure the selection of appropriate materials. Paper should have sufficient strength and toughness. Usually, kraft paper with appropriate gram weight and long fibers is selected. High-quality paper can withstand certain pressure and tension and reduce the risk of deformation. The quality of glue is also extremely critical. It is necessary to select glue with strong adhesion and good weather resistance to make the paper layers tightly bonded to prevent cracking. For example, the use of high-strength, water-resistant modified starch glue or synthetic resin glue can enhance the overall structural stability of the paper tube.
Secondly, optimize the production process parameters. During the winding process, the winding tension must be accurately controlled. Excessive tension can easily lead to excessive stretching of the paper, which is easy to deform in later use; too little tension will result in insufficient compactness of the paper tube. The optimal tension value is determined through multiple tests, and the tension control system is used for real-time monitoring and adjustment. At the same time, the winding speed is controlled to avoid loose bonding or wrinkles between paper layers due to excessive speed, which affects the quality of the paper tube.
In addition, the drying process of the paper tube should be strengthened. Insufficient drying will cause excessive moisture content inside the paper tube. As the water is lost during use, the tape paper tube shrinks unevenly, causing deformation and cracking. Use appropriate drying equipment and processes, such as hot air circulation drying, to ensure that the paper tube is dried evenly and reaches the appropriate moisture content standard, generally controlled between 8% and 12%.
In addition, standardize the use and storage environment. When using, avoid excessive external force, collision or falling of the paper tube. For heavier tape rolls, use appropriate support and handling methods to prevent excessive local force on the paper tube. When storing, it should be placed in a dry, ventilated and temperature-appropriate environment, avoid direct sunlight and humid environment, prevent paper from getting damp, aging, or deformation caused by thermal expansion and contraction due to temperature changes.
During transportation, take protective measures. Use cushioning materials to wrap the paper tube to prevent damage due to bumps and vibrations during transportation. Reasonably arrange the transportation space to avoid paper tubes squeezing each other or colliding with other hard objects.
It is also necessary to regularly check the use status of the tape paper tube. Once slight deformation or cracking is found, timely adjust the use method or perform repairs, such as adding glue to the local cracks to prevent the problem from getting worse.
By taking comprehensive measures in material selection, production process, use, storage, transportation, inspection and maintenance, etc., it is possible to effectively prevent deformation and cracking of tape paper tubes during use, extend their service life, and ensure the smooth progress of industrial production.
