What are the factors leading to air pollution in the printing industry?

How should it be controlled?

at present, China’s printing industry is facing great pressure on environmental protection. Because most of the inks used in printing contain organic solvents, and the organic solvents directly enter the atmosphere without any treatment, resulting in hundreds of thousands of tons of organic volatile matter (VOC) discharged into the atmosphere every year. In addition, the inks contain harmful heavy metal elements such as lead, chromium, cadmium, mercury, arsenic and barium, It does great harm to human body and environment. These substances have caused great pollution to the environment where we produce and live. We should develop and use green ink. What is green ink? Green ink is a relatively environmentally friendly product, which contains the following three meanings
(1) it is necessary to significantly reduce the harmful components of ink, mainly including reducing the content of aromatic hydrocarbons and ketones, reducing the content of heavy metals, reducing other components harmful to human body, etc
(2) the harm to operators and the environment in the process of ink production and use should be significantly reduced, and the front-line production environment should be improved. At the same time, the energy consumption of ink in the process of manufacturing and use does not increase significantly
(3) it should be conducive to the recycling and treatment of packaging waste, and there should be no “secondary pollution” and other situations

although at this stage, the research and development of environmental friendly ink in China is still restricted by many factors, for China’s ink industry, the ultimate goal is to finally realize the green ink in a broad sense, while manufacturing and promoting the green ink in a narrow sense is the current research goal and ultimate pursuit. With the development of technology, people begin to consider the factors such as convenience, cost and environmental protection performance
the main advantages of green ink are: it does not contain VOC harmful to human body and the environment, does not pollute the environment, has fast drying and curing speed, low energy consumption, high density of crosslinking and curing, and the degree of curing can reach 100%. It can be printed on a variety of substrates, and has excellent mechanical and physicochemical properties. Therefore, once energy curing ink is available, it is sought after by the market.
