Environmentally friendly soy ink

Foreign scientists have finally found a new type of environmentally friendly ink, soy ink, whose raw materials are salad oil and other edible oils. As a kind of refined vegetable oil, salad oil undergoes a series of rigorous decolorization, deodorization, and removal of free fatty acids and other refined processes. The soy ink has excellent fluidity and colorability, and is highly transparent, colorful, and not easy to fade.

According to industry insiders, the black ink used by the ancients was taken from pine smoke and coal and other materials, and ink was used for printing as ink and ink printing. At the beginning of the 19th century, with the rapid development of the printing and dyeing industry, ink was quickly replaced by chemical ink. The solvent in the chemical ink is derived from petroleum refining products and is a volatile organic compound. Therefore, newspapers, magazines, and books printed with chemical inks will continue to volatilize petroleum solvents, affecting people's health. In order to save wood resources, people make full use of old printed matter and waste paper. However, when they are recycled, they must undergo "decolorization." The decolorization of petroleum macromolecule compounds will pollute the environment through waste water, waste gas and other routes.

This situation has not changed, and now soybean ink can finally end it. Prints printed with soy ink do not produce toxic and hazardous substances that pollute the environment during use and recycling. Therefore, they are called environmentally friendly prints. Now when some print products using soy ink in the US and Europe are available on the market, they must be marked with the eye-catching mark “printing with environmentally friendly ink” to expand the social impact of environmental protection products.
