(Best practices for running coated liners on the corrugator) Generally, care must be taken when processing coated paperboard on a corrugating machine. Due to the fact that the surface of the coated paperboard has been glazed, it has a certain degree of moisture resistance, that is, Compared to kraft paper, the moisture permeability of coated paperboard is worse. Corrugated paper processors should clearly understand why coated paperboard is used. The quality of the paperboard will have an impact on the subsequent printing and paper product processing operations. Hiccups, adhesives, corrugations, and grooving are all potential problems. Therefore, these problems should be emphasized when producing on a corrugating machine, rather than waiting for and paying attention to when a failure occurs during printing and processing. The following suggestions are made for this particular situation. 1. Starch raises the starch content of the coating machine to at least 29%, which will help to improve the problems that occur when binding and rolling. There is no need to change the formula if S/F is bonded, but if the temperature or process changes, the temperature of the gel needs to be adjusted. Second, single-sided roll materials control the preheating and deformation pretreatment of single-sided roll materials to the minimum level, so as to maintain the high humidity and moisture content of the single-sided roll material as much as possible. The cardboard is pretreated with a moist air flow (above the drying air flow). Correspondingly, the starch content is increased and the material channels are sufficiently cooled. Third, the gluing roller and preheater for iodine test can get a lot of information on the type of glue, and should regularly perform iodine test. Check the amount of glue applied by the gluing roller and set an appropriate interval value (0.004-0.008 inch) to adjust the amount of glue applied. The larger the interval, the greater the amount of glue applied, and vice versa. The glue roller, reel tension roller and pressure roller must be parallel. Adjust the rotation speed of the coating roller to find the "best point" for the strongest adhesion. After leaving the preheater after gluing, the temperature of the board should be controlled within 180 degrees and the temperature difference should be kept within ±5 degrees. Temperature control and tension control are all very important factors. Fourth, the pressure roller conveyor belt and the hot sheet must ensure clean, clean, flat, heavier roller must also be kept horizontal. The temperature at the beginning of entering the hot sheet is low, and heat is gradually increased later. The spray water system is beneficial for any reverse deformation control. If the corrugating machine is equipped with a steam device, it can increase the moisture content of the roll material and increase the humidity, thus contributing to the winding control. After leaving the hot plate, the temperature of the bottom sheet should not be less than 200 degrees. Fifth, slitting, creasing, and cutting The sharp cutting knife, neatly arranged creases, and proper spacing settings can prevent the occurrence of powder failure and breakage, and ensure the quality of slitting, indentation and breaking. . 6. Conclusion The facts prove that the above mentioned suggestions are very useful in the operation of many corrugated paper machines. However, different corrugating machines have their own characteristics and external conditions. In addition, mere adjustment on the one hand often does not solve the problem. Therefore, the operator must determine what kind of adjustment is appropriate for his company's situation. In order to optimize the operation performance of the corrugating machine, routine maintenance and maintenance should be carried out to ensure that the corrugating machine always maintains a good operating condition. This must be observed and imperative.
