The honeycomb cardboard have different standard, even for the same thickness of honeycomb paperboard, function also will change according to the number of paper.
Change of thickness of honeycomb paperboard first by increasing or decreasing the thickness of the paper, the shape of the paper core has a great influence on the function of honeycomb paperboard, and also the same shape change.
Generally speaking, aperture than painting honeycomb core.
In general, when the shape of the honeycomb core near hexagonal honeycomb board of all the function is good, but under the condition of produce practice, difficult to produce with a hexagonal honeycomb core of the honeycomb cardboard.
First gathered in the functional index to carry on function research of honeycomb paperboard, the static and dynamic characteristic test, function theory modeling and computer finite element analysis of honeycomb paperboard.
Further discusses some of the basic features of the indicators of honeycomb paperboard, and draw the conclusion: the more quantitative honeycomb board used in the manufacture of the honeycomb cardboard, pressure resistance, abrasion resistance and wet resistance, the better, but the production cost is relatively large;
In the process of produce honeycomb cardboard, when core fiber paper and tissue arranged along the vertical direction, producing the compressive strength of honeycomb paperboard of;
Water content has a great influence on the function of paper materials, and water content of the honeycomb cardboard should be controlled in a reasonable range, when the moisture content of honeycomb paperboard was 3%, the compressive strength of the cardboard.
Base paper ring crush strength of honeycomb products pressure resistance and bearing ability has a great influence, cardboard flat crush strength increases with the increase of height of paper core.
This is a slow decline.
When the honeycomb cardboard opening rate is 1, the shape of the honeycomb paperboard core near the shape of a hexagonal honeycomb structure, and under these conditions, the function of honeycomb paperboard is good.
In the process of manufacturing of the honeycomb cardboard, every step is very special and strict, as long as such, produce of honeycomb paperboard talents and tidy condition.
Step, feeding unit: base paper is the original position of the honeycomb cardboard production line.
It is composed of two independent paper feed tray, each tray can move the paper independently.
At the bottom of the paper frame is equipped with a belt brake gas lift, can quickly and easily replace base paper.
In two steps, through sizing unit stretch: the honeycomb core will be continuous not foam honeycomb core stretching, boring and formed by stretching boring machine.
Honeycomb stretching of the boring machine speed can be adjusted according to the requirements of the production line to work on.
Three-step coating equipment: the honeycomb core is stretched and the honeycomb core boring unit formed after the honeycomb core through the double-sided adhesive coating machine in up and down sides of the honeycomb core, and can be separated and reduced.
The center of the paper core can reduce the use amount of glue, guarantee the bonding strength of honeycomb paperboard.
Four steps honeycomb cardboard composite unit: as a production line at the center of the organization, composite unit press paper on the lower layer and forming of honeycomb paperboard core, to form honeycomb cardboard.
According to the demand of produce the device to heat and paper honeycomb core to improve the speed of composite.
Dongguan industrial cardboard composite factory research and development, production and sales of industrial composite board.
