Problems solved by technology

Disadvantages of acid dissociation treatment: first, the dissociation rate of waste paper fibers is low; second, the operation is more troublesome and consumes a lot of power; third, the equipment used in the process has a great corrosion effect on the cooking equipment under acidic conditions due to the addition of aluminum sulfate , the equipment used in the whole process of processing waste wet-strength paper waste paper using this method must use corresponding anti-corrosion materials, and the investment cost of equipment is huge
Due to the high wet strength of this kind of waste paper during pulping, the fibers are not easy to dissociate and disperse, and there are many paper pieces in the pulp. When the pulp is remade, it is difficult to interweave between fibers to form a good network structure, and the paper variety is poor.
Usually, the dissociation method of waste wet-strength paper is to add aluminum sulfate under acidic conditions, but this method cannot effectively form pulp, the dissociation effect is poor, there are still small pieces of paper in the pulp, and it will cause serious corrosion to the papermaking equipment

Abstract

The invention discloses a method for preparing a dissociation treatment agent for waste impregnated paper with wet-strength. The method is characterized by comprising the following steps: (1) mixing 30-50 percent by mass of sodium hydrosulfite and 50-70 percent by mass of industrial anhydrous sodium sulfate; (2) drying and packaging to prepare a component B; (3) mixing 0.1-0.5 percent by weight of sodium tripolyphosphate, 0.1-1.5 percent by weight of solvent, 0.1-0.5 percent by weight of sodium dodecyl benzene sulfonate and 0.1-0.5 percent by weight of a penetrating agent; (4) mixing and filling to prepare a component A; (5) mixing the component A and the component B to prepare the dissociation treatment agent for waste impregnated paper with wet-strength. According to the method, the dissociation rate of waste paper can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of waste wet-strength paper dissociation treatment agent, in particular to a preparation method and application method of waste wet-strength paper dissociation treatment agent. Background technique [0002] In the production process of the paper industry, there are many types of paper mixed with wet strength agents, and a large amount of chemical raw materials and wet strength agents are mixed in paper with wet strength. But so far, there is no mature experience and related reports on the complete dissociation of waste paper containing high wet strength agents in the secondary treatment and utilization of industrial wet strength waste paper at home and abroad. How to avoid that when the paper made of high-quality fiber raw materials added with wet strength agent is reused, due to the technical conditions of the processing technology and the poor effect of the product formula composed of chemical raw materia...
