Stripper is called striping agent in English, and its attribute is the agent stripped off the wall of cooling tower. There are many paper mills that will produce paper cylinder sticking phenomenon in the process of paper making. In order to reduce and eliminate these phenomena, it is necessary to add stripping agent for drying cylinder.

Let's talk about the application of stripping agent.

1. Application of stripping agent in household paper: tissue is a kind of special thin paper with large output and low gram weight. As the new paper machine makes very fast, many enterprises choose mineral oil or vegetable oil emulsion, which can wrinkle and effectively peel off when used together with adhesive. Polymer wax strippers and paper softeners also have certain peeling properties, but the stripping effect is worse than that of mineral oil, but can increase the paper surface wrinkle fineness and brightness.

2. Coated paper: coated paper is a kind of special paper processed by surface coating. The coating solution of various coated paper is different, and its performance is also different. Some of these paper products require a very bright surface, such as glass cardboard, cast coated high gloss spray paper, etc. they are coated with pigment, dried by hot air, and contact with the casting cylinder under a certain pressure. After peeling off, the paper with high surface finish is produced. A certain amount of stripping agent, such as polymer wax emulsion or polyether stripper, should be put into the coating slurry of these paper. Cationic polymer wax emulsion stripper is especially suitable for the stripping of color ink-jet paper.

3. Thin paper: there are many kinds of thin paper, such as tea bag paper, mask paper, ecstasy paper, decorative paper, etc. generally, the weight of each paper is light. These papers are difficult to automatically leave the dryer, and a certain amount of stripping agent is needed. Due to the different application characteristics of thin paper, the most economical and suitable stripping agent can be selected. For example, because the tin foil is to be pasted on the surface of superstition paper, mineral oil stripping agent can not be used, otherwise, the tin foil will not stick on, so it is more suitable to use anionic polymer wax emulsion stripping agent. For example, mask paper, decorative paper can use cationic polymer wax emulsion stripping agent, can be added in the pulp can also be added before the net. The paper added with polymer wax emulsion stripper can improve the adaptability of printing and improve the adhesion of printing ink.
