Writing method and system capable of realizing paper recycling

Abstract

The invention discloses a writing method and system capable of realizing paper recycling. The writing method comprises steps as follows: a fluorescent quantum dot solution is obtained; a user writes on the surface of paper with the fluorescent quantum dot solution, and the written paper is obtained and carries writing content; the written paper is processed by the aid of an erasing agent corresponding to the fluorescent quantum dot solution, the writing content is erased, and the paper after erasing treatment is obtained; the paper after erasing treatment is neutralized by the aid of a neutralizing agent corresponding to the erasing agent, and the neutralized paper is obtained for use. With the adoption of the writing method, paper recycling is realized, and the writing content obtained after writing on the paper with the fluorescent quantum dot solution can be displayed for a long time. Further, according to the writing method, complex secondary treatment is not required to be performed on the paper, so that environmental pollution in the secondary treatment process can be avoided.

Description

technical field [0001] The present application relates to the technical field of resource recycling, and more specifically, to a writing method and writing system with reusable paper. Background technique [0002] Paper is an important information carrier and has played a very important role in the spread of human civilization. However, the current mainstream ink writing methods, carbon writing methods and inkjet printing methods can only make paper lose the possibility of writing again after one-time use, resulting in a large amount of waste of paper. The production of a large amount of paper will lead to the deforestation of a large number of forests, and will cause serious pollution to the environment during the papermaking process, so it is very important to realize the reusable writing of paper. [0003] In the prior art, paper is usually treated twice to make it reusable. For example, a reusable water writing paper is disclosed in the patent application CN103434309A,...
