Comments toxicology study led to the sin ink - ink, books - especially Indian silk industry Recently, the media scared newspapers and magazines, especially the new magazine can be a serious threat to human health and can cause dizziness, mild nausea, severe cases can cause genetic damage to bone marrow, white blood cells, thrombocytopenia and aplastic anemia and even leukemia. Young people often look at the new magazine, its damage will be greater. HC screen Special Indian network Recently, some media Jing Bao, magazines, in particular, the new magazine can be a serious threat to human health and can cause dizziness, mild nausea, severe cases can cause genetic damage to bone marrow, white blood cells, thrombocytopenia and aplastic anemia, and even leukemia. Young people often look at the new magazine, its damage will be greater. So how did one thing? What makes the magazine have become so secure? Comments ink fault Benzene, commonly known as the day that water is a special fragrance of the colorless transparent liquid, volatile, flammable, explosive vapor, evaporate quickly at room temperature. Inhalation of high concentration of benzene after subacute benzene poisoning, there dizzy, headache, fatigue, insomnia, menstrual disorders and other symptoms can occur in aplastic anemia, acute leukemia. According to experts, current books, packaging, printing ink used in a wide range of benzene, ethyl ether and the like as the main toxic organic reagents as the Solvent The content is generally 30% -70%, which not only led to the printing plant explosive threats that exist in the same time, there are easy-to-volatile type of solvent, the printing operation of workers and threatening the health of surrounding residents, but also to the consumer brought about by the great hidden issues. ( Is the non-phenyl ink NY ) Analysis of Ink Development Although as the countrys growing emphasis on environmental issues, the environmental performance of printing ink products also continues to grow, but the stability of the printing effect can be either a high degree of customer and makes the absolute cost advantage of benzene solvent inks still will in the future for a long time dominated the food packaging and printing industry in China. For domestic enterprises, whether from the enterprise development considerations, or factors from the human health considerations, domestic ink manufacturers should accelerate product upgrading to increase efforts to develop environmentally friendly ink, in order to better meet the needs of market development and . Ink composition description: Ink is important for the packaging printing materials, it will be through the printed pattern, the text shown in the substrate. Ink including the main components and auxiliary components, they are evenly mixed and formed by repeatedly rolling a viscous gel fluid. (1) the main component ink pigment. Including pigments and dyes, pigments organic pigments and inorganic pigments points, the former bright color, strong coloring, in the ink applied broadly, such as azo series, phthalocyanine blue pigments; which light resistance, heat resistance, solvent resistance , hidden forces are better, such as titanium dioxide, cadmium red, chrome green, ultramarine, etc.. Coloring pigment in particulate state, not dissolved, is the most commonly used pigment ink. The preparation of dye solution used, was colored molecular state, as effective as paint. Pigment ink will give different color and color density, and to a certain viscosity of ink and dryness. binders. Is also a major component of ink, pigment and auxiliary material from the dispersion medium effect, is a small natural resin, synthetic resin, cellulose, rubber, dry oil derivatives such as soluble or solvent obtained. Have a certain mobility of the printing ink to form a uniform thin layer, dry film formation of a certain intensity, and the protective paint, making it difficult to fall off. Link to material on the transfer of ink, brightness, solid-speed printability and printing the results have great impact, therefore, choose a suitable binder is one of the keys to ensure a good print, to be able to according to the packaging materials, printing different requirements at any time to adjust the composition of materials and ratio of links. (2) ink auxiliary components Ink assisted many of the ingredients, mainly in the following categories: filler. It is an ink concentration adjusting additives, but also increase the ink film thickness, to improve its wear resistance, it is not a color strength and hiding power. Mainly barium sulfate, calcium carbonate, such as aluminum hydroxide, when used to its pulverization into a white powder. thinner. Its role is to lower the ink viscosity, to prevent stripping phenomenon, so that ink with adaptive operations. The diluent used to have a low aggregation linseed oil, mineral oil. The former easily mixed with ink, the role of soft; the latter dilution effect is obvious, but avoid excess, or printing is not effective.
