Trend analysis of green materials

Recently, the national textbook "green printing" as the primary measures for promoting the development of green printing and has its special significance. Material objects for elementary and middle school students, teaching materials as a tool for learning, can be said to be what they had contact every day. At present, due to overall industry levels and people's safety, environmental awareness is not strong, and printing of teaching materials there are a lot of problems.
question: "ink" and "ink"
ink containing toxic chemicals in air diffusion, so that the ink issue that people say "ink". For textbook printing inks often contain ethanol, isopropanol, butanol, propanol, methyl ethyl ketone, ethyl acetate esters, volatile organic solvents such as toluene, xylene, which constantly volatile organic solvents in the printing process, and emit toxic, irritant smell more benzene material. Ink drying most of the solvents will be eliminated, but there will still be some residue, students read for a long time this type of ink printed on the book, inhaling the gas affects the brain central nervous system, pose a threat to health.
horror and not only that, the books used in printing inks, pigment fine particles, strong adsorption capacity, which contains heavy metals such as lead, chromium, cadmium, mercury, have some toxicity. Their emissions will not only cause damage to the natural environment and may lead to chronic poisoning, or through the blood to the brain, causing brain damage. According to the research, developing youth's degree of absorption in lead is several times higher than in adults, lead poisoning intelligence have a greater influence on young people. Ink, containing the ink and the body of heavy metals, especially students and children in close contact, the consequences would be unthinkable.
question two: "packaging" General textbook post-press binding of EVA hot-melt Adhesive and solvent film coating technology also contains volatile organic solvents, smell of solvent emitted is typically a carcinogen, harmful to students ' health and also damaged the environment.
in addition, the materials used in the production of paper that you want to add a large number of agents, whitening, fluorescence, greatly improving the whiteness of the paper, read for a long time can cause vision fatigue, especially primary and middle school students reading vision will fall quickly, and adding additives before discharge of wastewater also caused great impact on the environment. In order to prevent pollution, protect the health and safety of students, Green materials come into being.
policy support for Green materials in order to accelerate the process of green printing to promote, at the beginning of June 2010, Yan Xiaohong, Deputy Director of the press and publication Department convened about publishing and printing units this fall teaching materials using eco-friendly materials for the printing of pilot work, and indicates that this work by the Department's Print Management Division is in charge, Office of the printing technology Association of China Green promotion management cooperate fully.
elementary and middle schools textbook green printing printed pilot work in the, Beijing Normal University Press, and people education press, and people art press, and people music press, and education science press, and Shanghai education press and Shanghai language education press 7 home published units, Beijing beauty pass printing limited, and people education press printing factory, and Beijing capital printing works limited, and Sichuan Xinhua printing factory, and Sichuan Xinhua color printing works limited, and Sichuan Kam wish printing works limited, and Sichuan joint Cheung printing works limited, and High-tech zone of Chengdu color printing factory in Heilongjiang province, linyi, Shandong Xinhua printing logistics group, Shanghai Zhonghua printing co, commercial press Shanghai printing screen printing factory and more than more than 10 printing companies as well as Tianjin Toyo ink, Ltd, Hangzhou Toka ink Chemical Co, Wuxi Wanli adhesion materials co, Henkel (China) investments limited the production of environmentally friendly raw materials and other related products unit took part in the pilot project.
in September 2010, the press and publication administration and the People's Republic of China Ministry of environmental protection (hereinafter referred to as the Ministry of environmental protection) sign strategic cooperation agreement on the implementation of green printing, two areas of China printing technology association and environmental development specific Green printing implementation forward. And pointed out in the bulletin on green printing "from 2012 to 2013, in the printing industry-wide framework for building green printing. Formulated and published Green printing standards, gradually in areas such as paper tickets, food and drug packaging and green printing demonstration enterprise of green printing, green printing related support policies soon; green printing full coverage of basic primary and secondary school textbooks, accelerating the Green printing government procurement. "According to understand, since March 2, 2011 Environmental Protection Department issued implementation first printing national environmental standard environment logo products technology requirements Hou, first green printing certification work with of official expand, as March 2011 end of, the province (district, and city) reported to intends participate in green printing certification of enterprise total 319 home, which more than 60 more than enterprise submitted has certification information, more than 20 more than enterprise has accept has site certification check.
the Green printing printing Green primary and middle school textbooks as the breakthrough point, Cao Hong, Deputy Director of the General Administration of press and publication of Print Management Division said, popularization of green printing starts from the primary and secondary school textbooks, will gradually be extended to government procurement of printing, food and pharmaceutical packaging and printing field. This year, GAPP pilot in the 7 Publishing House, printed 100 kinds of teaching materials using environmentally friendly inks, glue, a total of 1500duowance, involving more than 20 provinces, municipalities and autonomous regions. You want to achieve in 3 years of primary and secondary materials green printing, green printing within 5 years to complete a full publication. BACK
