[0003] Among them, due to the printing quality, especially the paper material and ink material, which have the most direct impact on students' health and user experience, the toxic and harmful additives in inferior paper and the harmful solvents in inferior ink will have VOC when the homework is used for a long time The gas volatilizes into the use environment, and then causes VOC pollution to the surrounding environment. In a VOC-polluted environment for a long time, even in a low-concentration VOC volatilization environment, with the accumulation of long-term use, toxic substances will be in the user's body Enrichment, if things go on like this, will cause irreversible damage to the user's body
