Honeycomb paperboard production line adhesive usage

 In the production process of honeycomb paperboard production line, into a predetermined side length of paper core coating line in the original paper adhesive need, forming after the honeycomb paper core and box board paper adhesive. Adhesive quality directly will affect the quality and performance of honeycomb paperboard, the use of good quality adhesives can not only guarantee the honeycomb paperboard production line production quality, but also greatly ensure the compressive strength of honeycomb paperboard.
Otherwise, not only affects the quality of honeycomb paperboard, honeycomb paperboard production line makes progress down, will increase the cost of production, reduce the production efficiency, and even threatened the reputation of the company.
Then the honeycomb paperboard production line of adhesives used what are the requirements? First of all, in the production process of honeycomb paperboard, should strictly grasp the adhesive quality, play a good glue technology, and according to the changing weather conditions, timely control the use of. Usually the honeycomb paperboard production line need to use adhesive, its formula is unchanged, and this is not reasonable, especially to the changeable environment, should take some change.
The general honeycomb paperboard production line need to use adhesive, the solid content of 16%-19%, however, various factors will affect the adhesive formulations. As easy to damp weather caused the honeycomb cardboard moisture distribution difficulties, resulting in insufficient strength of paperboard is soft. In the production process of honeycomb paperboard production line, if encountered such a situation, suggestions of solid content can increase the adhesive, this can increase the adhesive film hardness, prevent glue excessive water seeping into the honeycomb paperboard.
If it is during the dry winter, so honeycomb paperboard production line need to use adhesive solid content it should be controlled at about 17%, otherwise it will cause the adhesive diffusion together with water, causing the board glue viscosity is not enough, then appears loose adhesion.
For honeycomb paperboard production line used adhesive is more than these requirements. Also in the adhesive during configuration and the honeycomb paperboard production line production personnel should pay special attention to stir a reasonable time, environmental changes will require different stirring time of solvent. Such as high temperature in summer, the stirring time is 30 minutes, the temperature is low in winter, about control in about 45 minutes stirring time, before delivery or use adhesive.
In addition, it is worth noting that honeycomb paperboard production line need to use adhesive if stored for a long time, there will be retrogradation phenomenon, some place to second days adhesive solid content increase, the viscosity is too thick, flow is slow, the actual use of after will find poor effect, not easy to board penetration, that most adhesives in the cardboard surface dry, this is the so-called “false stick” phenomenon.
