Polymer-aldehyde additives to improve paper properties |
摘要 |
The strength properties of paper are improved by treating the paper with a hydroxy-containing polymer, a multifunctional aldehyde and a catalyst. The multifunctional aldehyde is present at a concentration of about 50% to about 800% weight percent of the polymer, the catalyst is present at a weight ratio of between about 1:0.1 to about 1:2 multifunctional aldehyde:catalyst and the total weight of the polymer, aldehyde and catalyst is between about 0.1% to about 10% based on the dry weight of the paper. |
