Today and people together for a good analysis of corrugated board
was the cause of the bubble, the temperature when the tile line just boot, the temperature of the each part of the equipment is still in heating, condensation water precipitation in the corrugated roller and pressure roller, then a foaming phenomenon is present.
Because the roller with water, causing the corrugated roller and pressure roller, temperature caused the paper to temperature, bad form bonding.
All we need to look at the siphon, and see whether there is water in the steam roller accumulation, if there is a clear water, adjust the orientation of the siphon.
In addition to see the steam input pipe and return line, the pressure difference between the normal operation of small pressure difference shall not be less than 4 kg.
Corrugated roller when corrugated roller is not heating, vacuum chamber on the corrugated roller is used to obtain the vacuum effect, will form the upper and lower the deformation of the corrugated roller and forming corrugated molding bad, in the present paper blister problem.
At this time that the corrugated roller and the corrugated roller can be out, and make them idle after stop working.
If possible, reshipment heated corrugated roller.
If take the following measures than corrugated roller under the condition of cooling the startup cost can also be less consideration: block core paper and single machine idle, until you reach the temperature, and then reinstall the core paper and start, so that it can be solved.
