Cardboard production
Honeycomb cardboard production process: first step: paper.The honeycomb cardboard we see was composed of two independent original paper, and the machine placed two original paper on the production line.Step 2: Honeycomb paper core fixed type.During the production process, in order to facilitate operation and storage, the honeycomb paper core is generally rolled into a bundle.Therefore, when we use the honeycomb paper core, we must first stretch and qualitative the honeycomb paper core to ensure that our honeycomb paper core is flat.Step 3: Honeycomb paper core adhesive.The honeycomb paper core after the stretching and shape is very flat. At this time, we paint a layer of glue on both sides of the honeycomb paper core. It does not require too much, but it must be uniform, so as to ensure that the honeycomb paper core and the original paper are the original paper.The bonding strength.Step 4: Honeycomb cardboard composite.In this step, the honeycomb paper core is compounded with the original paper. In the last step, we have already applied glue to both sides of the honeycomb paper core.At this time, we only need to bond the original paper with the honeycomb paper core. Due to the time, we can warm up in order to improve the bonding speed.
Cardboard material
First, the main purpose of the cardboard of cowhide box cardboard is to pack long -distance cardboard.The strength of this cardboard is relatively large. When it is made, it uses crude fiber, so the cowhide cardboard is more tough and strong.Second, the main purpose of the cardboard of the insulating cardboard is the transformer, circuit breaker and other electricity -related devices.This paper uses fine fibers (poplars, willow trees, wheat straw, etc.) as raw materials.Third, the cardboard of sound insulation cardboard is generally used in our KTV. The material of the sound insulation cardboard is the same as that of the ordinary cardboard. It is a loose paper layer with gaps in the inner layer of a sound insulation cardboard.This layer of paper layers to absorb noise.
