2013年关于上胶和覆涂十篇****文章

wound core wind rewind PFFC (Paper, Film & Foil Converting) announces their 10 Most Popular Stories of 2013. Here are the highlights. Claudia Hine started the year off with a recap of the Top 11 New Products of 2012. The previous year's innovations focused on improvements in web coating and laminating processes mostly in the packaging industry. Mark Miller of Coating Matters began the year trying to explain fluid coating technology to people familiar with extrusion technology. In his blog, Read more Corona Treating for Coating Applications Verner Eisby inventor of corona treatment Maintaining high quality coating on paper, film, metalized film and foil substrates at production line speeds requires a method of enhancing substrate surface energy. Corona treatment promotes bond sites and increases surface energy without sacrificing the positive properties of the substrate. In coating applications, treater system design has undergone significant changes to accommodate lighter webs, higher line speed operation and advanced substrates. The range of developments has included the requirement for handling conductive substrates, nips at the treater roll, using the treater roll as a "pull roll," and modifying the treater station design... Read more Part 8: Mechanical Design of the Reverse Roll Coater Reverse Roll Coaters must be of Uncompromised Precision In Part 7 of this series on reverse roll coating we discuss the use of hydraulic force to control Metering Roll Ratio and Capillary Number. The mechanical design of the Reverse Roll Coater must be uncompromised when it comes to precision. Rolls must be made of high strength steel or cast iron of sufficient diameter and wall thickness to provide substantial resistance to the gap separating forces encountered... Read more Part 7: Using Hydraulic Force to control the Capillary Number and Metering Roll Ratio In Part 6 we discussed the affects of non newtonian flow and viscoelasticity on reverse roll coating. One other factor affected by both the capillary number and the metering roll ratio is the roll separating force exerted by the coating as it passes through the converging geometry of the metering gap. See Figure 7. This hydraulic force is proportional to the capillary number so it increases with both viscosity and applicator roll speed. At some point, this force can cause the rolls to... Read more Part 6: Affects of Non Newtonian Flow and Viscoelasticity on Reverse Roll Coating Non Newtonian Flow vs. Viscoelasticity In Part 5 we discussed how the metering roll ratio and the capillary number control the position of the wetting line in reverse roll coating. Other complications that are likely to be encountered are the rheological considerations of non Newtonian (typically shear thinning) flow and viscoelasticity. Viscoelasticity occurs when a liquid possesses the ability to extend and relax in response to the application and subsequent removal of a shearing force. It is a liquid possessing a... Read more Part 5: Controlling the Position of the Wetting Line in Reverse Roll Coating Metering Roll Ratio vs. Capillary Number to Increase/Decrease the Wetting Line In Part 4 of this series we discussed how the position of this wetting line affects the ribbing and cascading phenomena in reverse roll coating. The most important factor in controlling the position of the wetting line is the metering roll ratio. The second most important factor influencing the position of the dynamic wetting line is the capillary number of the coating. The capillary number is defined as: Read more Part 4: Position of the Wetting Line Affects Roll Coating Thickness How the Wetting Line Affects Ribbing and Cascading in Roll Coating Thickness In Part 3 of this series we discussed how to control defects in metered roll coating to prevent ribbing and cascading. In Part 4 we discuss how the position of this wetting line affects the thickness of the metered coating and the ribbing and cascading phenomena. The "wetting line" as illustrated in Figure 5 can be described as the point at which the coating pulls away from the metering roll as it... Read more Part 3: Factors that Influence Defects in Metered Roll Coating Controlling Ribbing and Cascading in Metered Roll Coating Part 1 and Part 2 of this series we discussed how reverse roll coating 1) can be used to apply a broad range of coating viscosities, 2) can apply these coatings over a broad range of thicknesses, and 3) can function over an equally broad speed range. Attempts to define limits are only generalizations, because there is an interdependency among all these... Read more Part 2: Two Basic Approaches to Reverse Roll Coating Nip Fed Reverse Roll Coating vs. Pan Fed Reverse Roll Coating Reverse roll coating appears in two basic forms - the nip fed and the pan fed. There are various configurations of each that have been deployed over the years, but the current popularity of two basic approaches really stands out today. The first of these is commonly described as the 3-roll nip fed reverse roll coating. The metering and applicator rolls have already been described in Part 1 of this Series. The third roll... Read more Part 1: Conditions of the Reverse Roll Coater Meeting the Requirements of the Reverse Roll Coater The use of a coating device known as the "reverse roll coater" is widespread in the coating of various thin films onto a variety of substrates. The metering and applicating mechanisms employed by this type of coater make it adaptable to this broad usage. To qualify as a true reverse roll coater, two conditions must be met. The first is the requirement for a reverse metering nip (gap). This occurs when the coating must pass between two rolls whose surfaces are travelng in opposite directions. This is illustrated in...

PFFC(纸张、胶片和箔转换行业)宣布2013年度10 篇****文章。详看如下

克罗地亚 海因在开年之初概述了2012年的11种新产品。 2012年的创新主要聚焦在专注于改善包装行业卷材上胶和覆涂工艺上。

“上胶”杂志马克 弥勒在开年之初尝试让熟知挤出技术的人们认识流体上胶技术。在其博客“混乱的世界”里，弥勒把产生对话比作“男人来自火星，女人来自金星”那本书里面的摘要。

二月份，迪尼 泰勒博士在他的博客印刷电子行业里讨论导电油墨和涂料实际运用。在线打印。

在四月份，弥勒重新回到解释何为流体涂料基础知识，并在其博客“涂料的基础”中写道关于为何转换行业如此受到重视。
