Abstract

The invention relates to the technical field of paper sludge, and in particular to a paper sludge preparation method and a paper sludge preservation method. The paper sludge preparation method comprises the following steps: (A) collecting waste paper, and crushing the waste paper so as to obtain scrap paper; (B) soaking the scrap paper, stirring the scrap paper, dehydrating the scrap paper, and purpling the scrap paper so as to obtain paper pulp; and (C) adding a conditioning agent into the paper pulp, and performing stirring, thereby obtaining paper sludge, wherein the weight part ratio of the paper pulp to the conditioning agent is (1-2):(3-5); and the conditioning agent comprises the following raw materials in parts by weight: 1000-1200 parts of water, 300-400 parts of white latex, 750-900 parts of cellulose, 0.1-5 parts of a dispersing agent and 1-5 parts of a preservative. The paper sludge prepared by using the paper sludge preparation method is free of cracking when being dried, is dry and firm, is free of moisture absorption, and is good in texture quality after being hardened; and paper cakes which are prepared from the paper pulp through extrusion, dehydration and drying can be preserved for a long time, and the paper pulp does not stink.

Description

technical field [0001] The invention relates to the technical field of paper mud preparation, in particular to a method for preparing paper mud and a method for preserving paper pulp. Background technique [0002] Paper is an important resource. The appearance of paper is definitely of epoch-making significance. It is not only closely related to human life and learning, but also directly affects the inheritance of human civilization! With the constant development of paper, paper is ubiquitous in life, and the amount of paper used is huge, but the use of paper also brings about the problem of waste paper disposal. "Waste paper recycling" has become a major issue in the field of environmental protection in all countries around the world, and It is also necessary to pass on the awareness of cherishing paper resources to the younger generations, so that the good habit of saving resources can be fully implemented. Especially for the education of elementary school students, guidi...
