Twenty years ago, due to the long-term closure of the country, China's packaging printing ink industry raw materials have not completely shake off imports, and its production pattern is under the planned economic system, the formation of a short-term national ink industry system. It is very fragile. The number of enterprises is less than 20, and the annual output is less than 20,000 tons (less than 0.05kg per capita). It was only 1/34 of the annual output of the United States and 1/20 of the consumption.
With the advent of the market economy, especially the establishment and improvement of the packaging industry and association institutions, the country has formed a production pattern of state-owned (owned), collective, joint venture, and private and individual multi-existence. It has developed to nearly 1,000 different sizes. The number of companies (actually registered as many as 560). Ink is also classified by stereotypes and ordinary engraving gravure, curing, anti-counterfeit inks, etc. The varieties are basically complete. It can also earn foreign exchange through exports, and its annual output has soared to 75,000 tons (per capita reached 0.12kg). Product output and consumption have almost doubled and doubled in 20 years. According to the current spot inspection of ink products, it is known that the pass rate is 80%, basically relied on other countries' raw materials and high-priced imported high-grade ink products to become a beautiful landscape on the packaging industry, which has become a hot spot for domestic and international attention.
Development Trends In the knowledge economy, the characteristics of packaging and printing inks are no longer simply the pursuit of mechanized operations (including platemaking, etc.) to adapt to large prints. The printed images are bright and beautiful, and high-tech is used to continuously upgrade and upgrade, and master and strive to surpass the world. First-class production technology for packaging printing inks. Instead, while changing concepts, we must continue to eliminate backwards and create advanced ones. For example, the development and application of ink on the desktop light-print digital system has promoted the fast pace of daily life and work. For many years, we have focused on production technology, especially synthetic materials technology, which not only consumes working hours but also pollutes the environment. All kinds of packaging and printing ink products used and produced are inert materials. They are only processed by physical means to adapt to packaging printing. The packaged articles are dampened and deteriorated after a certain time limit, and even the solvent toxicity of the ink system penetrates or migrates into the articles, and the scrapping of the goods has long been commonplace. The remedial measures are nothing more than: apply a layer of moisture-proof polish or a layer of printing material or choose a material several times thicker. This passive mode of operation is called inert packaging printing material technology.
With the development of the knowledge economy, the establishment of information highways, the spread of networking, and the frequent industry-wide exchanges, the application field has been greatly expanded. Design advertising, printing machinery, photoengraving, computer arrangement, printing materials, nanotechnology The research, development and application of technology and additives are increasingly valued by the ink industry. Because it can greatly improve the production process, improve the production conditions, increase the added value of products, and give special functions, it has become an indispensable part of the ink system. Its application level has become an important indicator of the level of ink production technology. In this way, employees can not only understand the colorimetry, rheology, body chemistry, grease chemistry, synthetic resin chemistry, and pigment intermediate chemistry involved in professional technology, but also analyze molecular chemistry, physical chemistry, and molecular coloring of inks or ions. Coloring or physical coloring, as well as methods for assessing gray balance of trichromatic inks in the Munsell color system, among others. Also learned a lot of external application knowledge - science and information - production and life - resources and the environment one by one application and marketing science and technology. The scientific research and exploration experiment of compounding and high-efficiency additive materials have been vigorously promoted, and the emphasis on professional coordination has become the fashion of today.
A. Using supercritical fluid extraction technology, coupled with kinetic and vegetable oil extraction coupling agent, neutral neutral super dispersant, added to the ink system, greatly reducing the thickness of the ink film, improving the degree of branching, interfacial adhesion fastness, and glossiness. Change.
B. The natural inorganic powder produced using the ultrafine powder technology can be made into 0.001um pigments with a small density but a large specific volume. Adding to the ink system is not only cheaper than organic materials, but also has hiding power and fastness comparable to that of organic pigment materials and has no toxic or side effects. The new properties of the microparticulated particles may also be reflected in the magnetic properties, activity, heat resistance, light absorption, surface tension, and melting point of the particles.
C. The patented new product—molecular wax distillation using molecular distillation technology, uses the difference in the mean free path of molecular motion to catalyze and oxidize the micro-wax and ordinary paraffin binary materials at a temperature well below the boiling point, separating them into complex compounds. Similar to the performance of beeswax, it can dissolve the ink special wax at the normal temperature of the solution and reduce the pollution source of the ink production process.
D. The microcapsule technology has succeeded in forming one or more coating films on the surface of ink pigments, which greatly improves the wettability and dispersibility of the pigments in the dispersion medium. For example, different anti-counterfeit ink colorants are made of different microcapsule pigments with various properties such as good coloring power, gloss, light resistance, heat resistance, solvent resistance and the like by selecting different coating materials. And can effectively reduce the toxicity and volatility of certain components of the ink system, the product will not be due to the storage period is too long and cause the product to be damp and deterioration.
E. The appearance of photonic computers, known as photon brains, can be calculated quickly in synchronization with light, which is 1000 times faster than current computing speeds of computers. Ingredients such as initiators, photosensitizers, antioxidants, anti-settling agents, etc., have become China's ink color matching and pollution-free light curing, anti-counterfeiting and other packaging printing inks reaching the international advanced level, shortened with developed countries The gap achieved the goal of integration and integration after entering the customs.
Exploration is the continuation of production, and practice is the accumulation of science and technology. As the pace of entry into the country accelerates and the country's doors are wide open, the international competition in the ink industry will become even fiercer. The use of advanced science and technology to develop, promote the use of "green packaging printing ink", "green printing non-printing ink", "functional solid packaging printing ink" and other green ink products. It will bring new opportunities and new vitality to China's packaging industry. (To be continued)
