Problems solved by technology

[0002] Acid pure blue ink is the ink commonly used in people's writing. For the mistakes that occur during the writing process, since the ink will immediately soak into the paper, it cannot be corrected with an eraser like a pencil and ballpoint pen, but with correction fluid and correction tape. Covering or modifying with erasing liquid and correction liquid has the following disadvantages: 1. There are obvious traces left in the modified place; 2. The materials used for correction not only contain substances that are not conducive to human health, but are also not conducive to environmental protection; 3. Eraser and correction fluid are inconvenient to use and the effect is not good

Embodiment Construction

[0009] First weigh 500 grams of sodium sulfite and 20 grams of carbolic acid with an electronic scale according to the aforementioned proportions, and use two measuring cups to measure out 5 liters (500 grams) of warm water respectively, put sodium sulfite into the container, add 5 liters of warm water, mix and stir until completely Dissolve, put carbolic acid into another container, add 5 liters of warm water to dissolve (pay attention to the corrosivity of carbolic acid during operation), then put the two solutions into a large container, mix and stir, and let stand for 7 days to make each group After the chemical reaction between the parts is completely carried out, and the insoluble matter generated during the reaction is fully precipitated, the clarified liquid on the upper part of the mixed liquid is sucked by siphon method and filtered with a filter cloth, and the filtered liquid is made into correction fluid.

Abstract

The present invention is correction fluid specially for acid blue ink and its making process. The correction fluid is made with sulfite 2-10 wt% and carbolic acid 0.1-0.3 wt% except water and the making process includes dissolving sulfite and carbolic acid in water separating, the subsequent mixing of the two kinds of solution via stirring, stagnation and filtering to obtain the correction fluid. The present invention has the advantages of simple production process, convenient use, no harm to human body and no environmental pollution.
