Technological innovation of manufacturing process of paper packaging materials
Publisher：admin Release time:2017-08-04 The quality of corrugated box is particularly sensitive to the strength of corrugated box, if the quality of corrugated paper is not good, the quality of corrugated box is not good. And by adding nano - materials in the corrugated production process, such as the special process made of corrugated paper, compared with the ordinary process of corrugated paper, has higher strength, and has good dehydration performance, not to lose powder, not to lose hair and other good advantages. Because the particles of the nanoparticles are very small, the concave and convex points on the corrugated surface are reduced relatively. And the fine smooth paper, the amount of adhesive is relatively little, so through the single knitting machine molding corrugated quality.The main production technology of nano - corrugated paper is: using nano - calcium carbonate materials and excellent additives, after the special equipment processing, a new type of paper additives for the nano technology was made. after adding this additive directly to the concentration of about 1 %, the paper made the paper machine cluster tube flow box, and sprayed evenly into the corrugated cardboard, so as to make the corrugated cardboard contain nano - calcium carbonate.
Because the nano - calcium carbonate contains positive and negative fiber, under the auxiliary effect of the auxiliary, about 80 % of nanometer calcium carbonate is stuck in the corrugated paper, after the high vacuum dehydration, crushing treatment, high temperature drying process, the formation water is about 8 % nano - corrugated. Using the nano - calcium carbonate material made of corrugated paper, its strength greatly improved, can be made of thin corrugated paper. For example, using the low - quantity nano - corrugated cardboard box with 80g / m2, the strength can be up and down with the quality of the cardboard box made of about 150 g / m2 corrugated cardboard. It can be said that the nano corrugated paper is an important way to improve the quality of corrugated box. In addition, nano ink, nano - printing plate, nano - adhesive, nano varnish and other innovative materials, expand the printing and post - press production materials function, to effectively reduce production quality failures, improve production efficiency has a better role.
