Strengthening Of Corrugated Boards By Chemical Impregnation, Rajesh Premnarayansingh
Masters Theses
Linerboards are used for making corrugated boards. The paperboards can be strengthened by adding strength additives at the wet-end of the paper machine and also by sizing them. Impregnation is another effective approach of strengthening the paperboards, mostly offline. The aim of the thesis is to evaluate the performance of the modified Dixon coater and check the operating conditions with various chemicals used for impregnating 42 lb/1000 sq.ft grammage linerboard.
The major conclusions of the research were that the edge compression strength increases markedly validating the usage of impregnation for linerboards. Also, the stiffness of linerboard increases and the voids …
