The hottest reason to choose soybean ink

Reasons for choosing soybean ink

environmental friendly soybean ink has gone through a long time from research and development to application. It has been applied on a large scale in the United States, Japan and other countries, but its application in China is still quite small. Among them, there are technical factors, and more importantly, it is due to lack of understanding. This paper introduces in detail the performance types of this kind of ink, and its application status and prospects in printing. Soybean ink (soy ink or vegetable ink) is made of vegetable oil such as salad oil, which has excellent fluidity and coloring, high transparency, bright colors, not easy to fade, low price, good printing effect, and conforms to various standard specifications of printing ink. Of course, the biggest feature is that it is very environmentally friendly

characteristics and advantages

PAH (polycyclic aromatic hydrocarbons) contained in traditional ink components is a volatile solvent, which is harmful to human body; VOC (volatile organic compounds) contained in it will not only increase air pollution, but also cause harm to human body. At the same time, with the rising oil price and the depletion of reserves, we need to find a new environmentally friendly material to replace the traditional ink ingredients. Soybean ink came into being, which has the following characteristics and advantages

good environmental protection performance

soybean oil contained in soybean ink is a safe substance, which replaces some petroleum solvents. The content of polycyclic aromatic hydrocarbons is low, and the emission of VOC is reduced when used,

so as to reduce the harm to the environment, and it is also conducive to the health of manufacturers and users

at the same time, the oil that traditional ink relies on is a non renewable resource, which is increasingly exhausted with use, the energy crisis continues to break out, and the oil price continues to rise. The oil manufacturing industry has begun to target renewable plant resources. The soybean oil used in soybean ink is natural, renewable and biodegradable. It has incomparable advantages over traditional ink in terms of resource utilization and environmental protection

good deinking and regeneration performance

waste paper printed with soybean ink is easy to deink, and it has less damage to the fiber of the paper. This characteristic of soybean ink is conducive to the recycling of recycled paper industry. This characteristic is confirmed by the research of Western Michigan University, which is famous for its papermaking technology in the United States. Generally, the operation of newspaper paper 8 is simpler and more reliable than that of the traditional hydraulic universal experimental machine. More than 0% uses recycled paper. Using the characteristics of soybean ink, the waste paper has less waste during recycling, and the recycling cost is low, which is highly competitive in the industry. The waste soybean ink residue after deinking is relatively easy to degrade, which is conducive to sewage treatment and control the quality of discharged water

strong abrasion resistance

according to the American Newspaper Association, newspaper readers often have their hands stained with ink when reading. This is because the ink on the substrate is easy to rub off after printing with traditional ink. However, soybean inks are mainly solvents in this regard. The content of polycyclic aromatic hydrocarbons is low. When used, VOC emissions are reduced, which reduces the harm to the environment, and is also conducive to the health of manufacturers and users

at the same time, the oil that traditional ink relies on is a non renewable resource, which is increasingly exhausted with use, the energy crisis continues to break out, and the oil price continues to rise. The oil manufacturing industry has begun to target renewable plant resources. The soybean oil used in soybean ink is natural, renewable and biodegradable. It has incomparable advantages over traditional ink in terms of resource utilization and environmental protection

good deinking and regeneration performance

waste paper printed with soybean ink is easy to deink and has less damage to paper fibers. This characteristic of soybean ink is conducive to the recycling of recycled paper industry. This characteristic is confirmed by the research of Western Michigan University, which is famous for its papermaking technology in the United States. Generally, more than 80% of newspaper paper adopts recycled paper. Taking advantage of the characteristics of soybean ink, waste paper has less waste during recycling, low recycling cost, and is highly competitive in the industry. The waste soybean ink residue after deinking is relatively easy to degrade, which is conducive to sewage treatment and control the quality of discharged water

strong abrasion resistance

according to the American Newspaper Association, newspaper readers often have their hands stained with ink when reading. This is because the ink on the substrate is easy to rub off after printing with traditional ink. However, soybean ink has greatly improved in this regard. Soybean ink itself has strong friction resistance. For example, when the power is off, three steel balls on the iron embedded end face contact the magnetic end face, so that newspaper readers are not troubled by black hands, and there is no unpleasant stimulating odor. In this way, soybean ink plays an important role in this and will lead to the formulation of ink quality standards for the printing industry

good light and heat resistance

the boiling point of soybean ink is much higher than that of petroleum volatile components. When the oil is heated by laser printer or copier, it will not volatilize and stick to the paper, and will not pollute machine parts

good printability

because the research and development and production technology of soybean ink have been very mature, through the research on offset lithography, the printability of soybean ink, including emulsification characteristics, dryness, friction resistance, etc., has been greatly improved

good comprehensive performance

soybean ink has a wide range of colors, rich and bright colors, and a small amount of ink can show the effect that a large number of traditional inks can show. It is reported that the same amount of soybean ink can increase the printing volume by 10% - 15%, thus reducing the printing cost. In addition, because the traditional ink contains organic compounds, in order to avoid environmental pollution, its waste disposal has been a difficult problem for ink manufacturers and printers. However, soybean ink can be backfilled and mixed in new ink, which is not only conducive to environmental protection, but also aims to help customers solve complex design and manufacturing difficulties in single 1 platform, while also reducing production costs

common soybean inks

there are several environmental friendly soybean inks commonly seen in the market

(1) environmental friendly soybean ink (HP) advanced printing ink features: high concentration, ultra bright, ultra friction resistant, fast drying and stable printing adaptability

(2) environmental friendly soybean ink (MP) advanced printing ink features: high concentration, super friction resistance, fast drying and stable printing adaptability

(3) environmental friendly soybean ink (RP) standard printing ink features: Super friction resistance, fast drying and stable printing adaptability. Soybean inks with different formulas should be used in different printing forms. Table 1 shows the soybean oil content in different printing ink applications

application status and prospects

soybean ink has been used in Europe, the United States, Japan and other countries and regions for many years. It not only has the advantages of low pollution, low chirality and low benefit for recycled paper printing, so as to achieve environmental benefits, but also helps to establish a good image of manufacturers, and the market share is also increasing year by year

the application of soybean ink is the first in the newspaper industry. There are about 10000 newspapers in the United States, of which 1/3 have used soybean ink, especially more than 90% of the top 1500 large-scale newspapers have confirmed its effect and widely used soybean ink

in Japan, the application of soybean ink has just started. As the largest user of soybean ink in Japan, Panasonic Electric Co., Ltd. uses soybean ink to print the packaging instructions of its global electrical products, to show the company's attention and concern for environmental protection. As the soybean ink meets the current environmental protection requirements of Japan, it is believed that the consumption will double in the future

the use of soybean ink is still immature in China, but with the improvement of national quality, the enhancement of environmental protection awareness, and the further implementation of the concept of Green Olympics for the 2008 Beijing Olympic Games, all have created a good opportunity for the promotion and application of environmental friendly soybean ink
