Problems solved by technology

[0002] At present, the amount of packaging paper tubes is increasing day by day, but the production level is limited. The quality of the commonly used polyvinyl formal paper tube glue is uneven. It is difficult to control the temperature, pH and time of the condensation reaction. It is extremely harmful to the human body. Although a certain amount of formaldehyde neutralizer is added, the unavoidable residue still endangers the health of the paper tube glue production personnel and the paper tube factory operators. There will also be a small amount of formaldehyde in the rolled out paper tube Residues constitute a potential hazard to the health of the user. At the same time, the viscosity of the paper tube glue is poor, the time to destroy the paper fiber is long, the storage period is short, it is easy to deteriorate, and when the ambient temperature is low, it is easy to gel and has poor fluidity.
