Nanotechnology and Printing Industry (I)

I. Introduction

The scope covered by the printing industry is very wide, including not only cultural and paper printing supplies such as books, magazines, newspapers, forms, catalogues, flyers, posters, cards, calendars, calendars, etc., but also packaging, billboards, etc. The printing of the patterns required for the daily necessities of life such as fabrics, and even the circuit board manufacturing of the electronics industry also applies printing techniques. Due to the large number of items used in daily life for printing technology, many applied science engineering companies have been entering the field of printing materials and technology, and they are trying to create new opportunities for the development of printing technology. In recent years, the rise of nanotechnology in the world has indeed made many scientists eager to try or have already invested in R&D. However, it is undeniable that nanotechnology is still a novel technology for the printing industry. The Printing Industry Technology Research Center (hereinafter referred to as the "Indian Research Center") is the forerunner of domestic printing technology research and is responsible for the research and development of printing technology. The research and development of nano-printing materials is an important work item for the Center for Printing Research in the future. one. Currently, nanotechnology may not yet be widely used in the printing industry in China. Therefore, the development of nanotechnology for printing is a very good idea.

The following sections describe the development of nanotechnology in printed materials, the positioning of research centers in nanotechnology research, research methods, and future prospects.

Second, the development of nanotechnology in printed materials

Currently nanotechnology has progressed in printing materials such as nanopigments, nanoinks, and nanopaper. Domestically, among the printing-related materials, the research and development of nano pigments is the most recent development. At the 2002 Taiwan International Exhibition on Printing Materials, Xu Jingtian (2002) mentioned that the main difference between the nanoscale pigments that the laboratory has developed and the traditional pigments lies in the size of the pigment particles. Zhang Yihe, Xu Jingtian and Xu Shichang stated in the article “Pigmentation, Dispersion and Application” (2002) that through the improvement of the wet dispersion technology, the nanopigment has been used in 1997 in Miho City; ITRI The Institute of Chemical Industry has also invested in the research and development of nanotechnology for the pigmentation of pigments, and in 2001 officially validated the feasibility and reproducibility of production in the laboratory.

In ink, in 1994, XMX Corporation of Massachusetts, USA obtained a patent for the production of nanometer homogenous particulate material for printing ink; this patent uses “Nano metal particles can absorb all the light waves and make itself This is a method of increasing the purity and density of ink by adding black ink to the black ink, which also has the effect of scattering light. (QI Cheng, 2002a). In addition, the nano ink can also be used in various aspects of printing, such as printed circuit board conductive ink, electrostatic photocopying magnetic nano powder, UV ink containing nano-resin, glass ceramic ink and the use of nanometer particles light-emitting properties Security printing (Qi Cheng, 2002b).

On paper, the current use of nanotechnology in the paper industry has begun to enter practical production. For example: Henan Yinge Co., Ltd. in mainland China and the Nanotechnology Research Institute of Huazhong Normal University developed waterproof nylon paper with super hydrophobicity and Moisture resistance, special properties to increase the strength of the printing surface and reduce the rate of expansion and contraction (Qi Cheng, 2003). In the paper “Nano Technology and Printing Paper” (Ke Liling, Qiu Meiyi, 2003), it was mentioned that nanoscale inorganic materials and inorganic inorganic materials have been successfully applied in the paper industry.

Nanotechnology is not limited to the research and development of pigments, inks, and paper. Other technologies such as non-printed materials and printing plates can also be applied to nanotechnology. However, for the current situation of the research center, the implementation of ink and paper testing for many years, has a huge data of ink and paper data, for the ink, paper characteristics analysis is very sure, so first by the ink and paper into the nanotechnology research and development work It is the most appropriate approach. Therefore, the Institute of Informatics established a nanocomposite research and development alliance with a number of research and development companies in fiscal year 92 for the research and development of nano inks. At present, only a few units or companies in the country are developing nano-level inks. Even for the world, nano-inks are still novel products. It is believed that if R&D is successful, it will bring great shock to the ink and printing industry. In addition, the 93th year's specialization work also involved in the study of nano-paper and nano-ink, and discussed the issue of printability. The explanation of the word "printability" can be explained later.

Third, the position of the research center in nanotechnology research and development

The Institute of Printing Research has been engaged in research on printing color since the year of eighty-sixth, and the color field is still one of the central themes of research and development. However, in order to expand the vision of the printing industry, the promotion or transformation of printing technology and materials is a necessary way. In terms of the structure of the printing industry, the market share of traditional lithographic printing in the country has not been able to dominate the market in the past. Conversely, various kinds of printing technologies have been exported to various industries. Therefore, it is extremely appropriate and necessary for the printing center to develop nanomaterials at this time.

The “Nano Age” (Yang Bangyue eds., 2003) cites a quote from the National Science Foundation in 1991: “When we enter the 21st century, nanotechnology will have a major impact on the health, wealth and safety of the people of the world. The impact is at least as good as antibiotics, integrated circuits and synthetic polymers in the 20th century." From the above passage, we can see the importance of nanotechnology in the future. In addition, "Nanmi Technology in Chemicals and Materials Industry Survey" (Ma Zhenji et al., 2003) pointed out that the National Science Council conducted an industrial survey on the topics of Nanotechnology and was surveyed in 125 questionnaires. The company's category is dominated by the proportion of traditional industries such as rubber and plastics, and 95% of the companies surveyed have expressed demand for nanotechnology. This message made the research center colleagues optimistic about the future prospects of nanomaterials used in the printing industry, and is more confident in the development of nanocomposites for printing. However, as far as the current situation of the research center is concerned, there is a shortage of manpower and material resources. How can we independently complete the research and development of nano-printing materials? To solve this problem, we must start with the positioning of the center. At present, the position of the Research Center is to improve the printing technology and provide guidance for the R&D units upgrading the traditional industries. It focuses on solving problems in the application of technology; therefore, for nanomaterials, research and analysis will be conducted with the view of printing professionals. The printing and research center will focus on whether the viscosity and anti-split force of nano inks are suitable for printing; it also emphasizes the weather resistance, abrasion resistance, chemical resistance, high temperature resistance, high humidity, high pressure, and color appearance of the printed materials; and Nanopaper will focus on characteristics such as basis weight, whiteness, smoothness, tear strength, and ink absorption. In the development of materials, nano experts from the material sector will share this responsibility. To engage in research and development with this concept of professional division of labor is an extremely cost-effective method.
