Coating Formulations

The Ji’an PM No. 3 is the first linerboard machine in China to use multilayer curtain coating technology. Since successful startup at the end of 2011, further development has been carried out to optimize running conditions, coating formulations, and the base paper to provide a product with satisfactory quality and lower cost to manufacture. The key challenges include designing the base board structure for the desired mechanical strength, designing the surface properties for subsequent coating operations, optimizing the high-speed running of the curtain coater to enhance production efficiency, minimizing the amount of titanium dioxide in the coating color, and balancing the coated board properties to make them suitable for both offset and flexographic printing. The pilot and mill scale results show that curtain coating has a major positive impact on brightness, while smoothness is improved mainly by the blade coating and calendering conditions. Optimization of base board properties and the blade + curtain + blade concept has resulted in the successful use of 100% recycled fiber to produce base board. The optical, mechanical, and printability properties of the final coated board meet market requirements for both offset and flexographic printing. Machine runnability is excellent at the current speed of 1000 m/min, and titanium dioxide has been eliminated in the coating formulations without affecting the coating coverage. A significant improvement in the total cost of coated white liner production has been achieved, compared to the conventional concept of using virgin fiber in the top ply. Future development will focus on combining low cost with further quality improvements to make linerboard suitable for a wider range of end-use applications, including frozen-food packaging and folding boxboard.

Abstract Conventional hard automation such as linkage mechanisms or cam-driven mechanisms provide high speed capability at a low cost (using typically one actuator), but fail to provide the flexibility required in many industrial applications. Manufacturers are increasingly turning to multi-axis robots to fulfill flexibility demands. In many cases, however, the flexibility requirements are limited; i.e. a given pick-and-place unit may be required to perform only a handful of different operations. Therefore, the expensive robots are under-utilized. By incorporating flexibility in conventional linkage-type mechanisms, we are developing adjustable robotic mechanisms (ARMs) to serve as a middle ground between hard automation and overly flexible serial-jointed industrial robots.

Printing Ink

Nanotechnology, in the 21st century, is the biggest driving force in the development of technology and industry, which has its wide range of applications. In traditional industries, nanotechnology can be applied to the development of digital printing ink. Digital printing appears as a new printing technology in the 1990s, the 20th century. And in recent years, along with the trends of a global energy saving and carbon reduction, the concept of producing green products with low-carbon, water saving, energy abating, pollution decreasing attributes has arisen. The introduction of digital printing to textiles brings the speed, flexibility, wide areas of color selection, environmental protection and the potential of cost saving etc; the technology becomes a major breakthrough in the textile printing industry. The industry is committed to the technology of environmental friendly digital printing and goes toward to a new pattern of bright future in fashion design. While the globe puts effort to develop digital printing, the core technology should not only focuses on how to come up with high-speed, large amount, low-cost machines, but also the R & D to the making and applications of digital printing, which has a great impact on digital printing quality. At the present, the digital printing ink of the reactive ink / acidic ink is applied to cotton fabrics and the fabrics containing hemp content. The printing process is from the fabric pretreatment → inkjet printing →solid color processing → washing → drying. Moreover, sublimation transfer ink is applied to fabrics containing polyester fiber content; but it cannot be fully colored the fabrics of general 100% cotton and silk, which is the biggest drawback of this sublimation transfer ink. Therefore, this study, primarily through the Nanotechnology with green environmental protection and reduction of carbon from Mimaki Engineering Co., Ltd., captures the moral of the cultural patterns of the local characteristics by the techniques of changing, modeling, designing, and arranging on the patterns of dress design. And it uses computer graphics software, Adobe Photoshop & Illustrator, to draw and trim the separate pattern and the foursquare consecutive pattern for the completion of fashion pattern designs. And it applies the features of the nano pigment ink on the fabrics of cotton, hemp, silk, and polyester fiber to interpret the artistic style of the local through digitized programming language. The importing of nanotechnology refills new sources of industrial competition. This study expects to explore the nanotechnology digital printing and combine with the design of the clothing pattern transforming on the designs, grinding pigment molecules to nano ultra-fine level with reduced light scattering phenomena and good light purity. Fully demonstrating the features of natural bright color, the endurance of pigment water and the light fastness will be able to create a lager space of application and market in the digital printing industry.

A low-cost and high-speed electro-optic (EO) switch using the guest–host EO material Disperse Red 1/Polymethyl Methacrylate (DR1/PMMA) was designed and fabricated. The DR1/PMMA material presented a low processing cost, an excellent photostability and a large EO coefficient of 13.1 pm/V. To improve the performance of the switch, the in-plane buried electrode structure was introduced in the polymer Mach–Zehnder waveguide to improve the poling and modulating efficiency. The characteristic parameters of the waveguide and the electrodes were carefully designed and the fabrication process was strictly controlled. Under 1550 nm, the insertion loss of the device was 12.7 dB. The measured switching rise time and fall time of the switch were 50.00 ns and 54.29 ns, respectively.

AbstractThe purpose of this study is to evaluate the influence of competition level on running patterns for five playing position in the most successful 2014–2015 European rugby union team. Seventeen French rugby union championship and seven European rugby Champions Cup games were analysed. Global positioning system (sampling: 10 Hz) were used to determine high-speed movements, high-intensity accelerations, repeated high-intensity efforts and high-intensity micro-movements characteristics for five positional groups. During European Champions Cup games, front row forwards performed a higher number of repeated high-intensity efforts compared to National championship games (5.8±1.6 vs. 3.6±2.3; +61.1%), and back row forwards travelled greater distance both at high-speed movements (3.4±1.8 vs. 2.4±0.9 m·min-1; +41.7%) and after high-intensity accelerations (78.2±14.0 vs. 68.1 ±13.4 m; +14.8%). In backs, scrum halves carried out more high-intensity accelerations (24.7±3.1 vs. 14.8±5.0; +66.3%) whereas outside backs completed a higher number of high-speed movements (62.7±25.4 vs. 48.3±17.0; +29.8%) and repeated high-intensity efforts (13.5±4.6 vs. 9.7±4.9;  +39.2%). These results highlighted that the competition level affected the high-intensity activity differently among the five playing positions. Consequently, training programs in elite rugby should be tailored taking into account both the level of competition and the high-intensity running pattern of each playing position.

Happy Marriage

Glasses, in their different forms and compositions, have special properties that are not found in other materials. The combination of transparency and hardness at room temperature, combined with a suitable mechanical strength and excellent chemical durability, makes this material indispensable for many applications in different technological fields (as, for instance, the optical fibres which constitute the physical carrier for high-speed communication networks as well as the transducer for a wide range of high-performance sensors). For its part, ion-exchange from molten salts is a well-established, low-cost technology capable of modifying the chemical-physical properties of glass. The synergy between ion-exchange and glass has always been a happy marriage, from its ancient historical background for the realisation of wonderful artefacts, to the discovery of novel and fascinating solutions for modern technology (e.g., integrated optics). Getting inspiration from some hot topics related to the application context of this technique, the goal of this critical review is to show how ion-exchange in glass, far from being an obsolete process, can still have an important impact in everyday life, both at a merely commercial level as well as at that of frontier research.
