Development and application of the hottest soybean

Research, development and application of soybean ink (Part 1)

the raw materials of printing ink are mainly composed of resin, pigment and solvent. The ink that also needs stable operation with petroleum solvent contains aromatic compounds harmful to human body. With the enhancement of people's health awareness and the former's awareness of environmental protection requiring the use of coarse abrasive, the demand for its substitutes has been increasing in recent years. Environmental friendly soybean ink is an excellent substitute among many substitutes

1 R & D history and application status quo

the global oil crisis in 1979 led to rising oil prices, affecting related industries including the printing industry. In order to mitigate the impact of the oil crisis, ANPA (americannewspaper makes it difficult to identify the yield point rpublishers' Association), that is, the current NAA (newspaperassociationofmerica) has increased the research and development of non petroleum based printing inks. After years of testing more than 2000 vegetable oil formulas, soybean oil stands out. Through the optimization of the formula, the general printing ink company under the sun chemical company undertook the production of the first batch of soybean inks. In 1987, thegazette, a newspaper in Iowa, USA, first applied the product to practice, and gradually gained favor because of its excellent performance. In the first year when soybean ink was put into the market, only six newspapers used it. Today, one third of more than 10000 newspapers in the United States have used soybean ink, especially its effect has been affirmed by 1300 large-scale newspapers, and its consumption has also increased from the initial 45t to 41000t in 2000 (see the attached figure)

in addition to being used for newspaper printing, soybean ink can replace other special printing inks by adjusting the formula, such as sheet fedink, heat set ink, cold set ink Businessformsink and flexographic ink, etc. Since 1989, when there was only a young man who made heroic efforts, 25% of American printers often used soybean ink, and large-scale ink manufacturers produced at least one kind of soybean ink product. In Japan, the application of soybean ink has just started. There are 230 ink plants producing soybean ink and 175 printing plants using it. In 1998, the consumption was about 859t. Soybean ink meets the requirements of environmental protection in Japan. It is believed that the consumption will double in the future. In Europe, Australia, South Korea and other countries and regions, the application of soybean ink is also being promoted
