Corrugated Board Strength--The Influence of Technical Workers and Environment

The influence of staff's technical level on the strength of corrugated board

In order to ensure the corrugation strength of the paperboard carton, the amount of glue applied should not be too large. However, in order to avoid degumming, some employees in the actual production have to increase the amount of glue. This is inadequate, and must be strictly controlled. The amount of glue should be 80g-110g/m2. However, depending on the size of the corrugator, it is advisable to control the amount of rubber evenly to coat the peak, as long as it does not degumming, the smaller the amount of glue, the better. Judging the amount of glue can be observed by the width of the paste line, should be 1mm-1.5mm appropriate. The advantage of recording the bonding of each single-sided machine and double-sided machine, respectively, lies in the correct judgment and resolution of equipment failures. Such as: paste paste roller wear. When calculating the amount of adhesive coating, it is best to use the amount of dry starch required for corrugated board per unit area. This expression method is convenient for the coating of adhesives for one week or whole month from the purchased raw materials or batches of feed amount. Cloth amount. In this way, certain requirements are put forward for the technical level of the staff. The reason analysis and solutions are shown in Table 4.

Influence of Environment on Corrugated Board Strength

The temperature of the production environment should not exceed 33°C, and the humidity of the air should not exceed 45%. Otherwise, the cardboard can easily absorb moisture, and its moisture is not volatilized, which naturally reduces the bearing pressure of the cardboard. Due to the urgent needs of customers, fans can be forced to blow air to promote the adhesion of the cardboard as soon as possible and remove excess moisture. The reason analysis and solution are shown in Table 5.

In summary, there are many factors that affect the strength index of the board, the quality of raw materials, the status of production equipment, and the appropriate conditions for the control of the production process. Carefully controlling the raw materials to the production process can effectively improve the product quality of the board.
