An expanded abstract and PDF of the full paper is available for download on our Website: AbstractSlot coating is one of the preferred, precision coating methods in the manufacturing of single- and two-layer coated products. The thickness of the coated liquid layer, in principle, is set by the flow rate fed to the die and the speed of the substrate moving past, and is independent of other process variables, being ideal for high-precision coating. The region in the space of operating parameters where the delivered liquid layer is adequately uniform is referred to as a coating window . The coating window can be determined by extensive pilot-plant experiments or by a complete analysis of the coating flow and its stability limits. A summary of the fundamentals of the slot-coating process and its operability limits is discussed, together with some aspects of advanced research being pursued.IntroductionIn earlier days, coating technology was developed as an art. However, the coating process is a complex, multidisciplinary science that involves wetting, adhesion, fluid mechanics, rheology, chemistry, interfacial science and heat, and mass transfer. Competitive pressure reduces the time available to bring new products into the market, and process development through extensive pilot-plant trials may delay production. Thus, it is important to analyze the physical mechanisms responsible for the success or failure of manufacturing processes. Process engineers should not pursue only process know-how, but also process know-why .Fundamental understanding of basic mechanisms involved in all phases of the manufacturing of coated films, including liquid preparation, coating and solidification requires long-term investment in process research and development, and specially-designed experimental and numerical analysis tools.Fundamentals ofthe slot-coating processBy Professor Marcio Carvalho, Dept. of Mechanical Engineering, Pontifica Universidade Catolica do Rio de Janeiro (PUC-Rio)Slot coating process has been deeply studied and understood. Here, we will discuss some of the fundamental aspects of this process and recent developments related to coating flow of particulate suspensions.Slot-coating operability windowIn slot coating, the liquid ispumped to a coating die in which an elongated chamber distributes it across the width of a narrow slot, through which the flow-rate-per-unit width at the slot exit is made uniform. Exiting the slot, the liquid fills – wholly or partially – the gap between the adjacent die lips while the substrate translates rapidly past them. The liquid in the gap – bound upstream and downstream by gas-liquid interfaces, or menisci – forms the coating bead (seeFigure 1). The competition among viscous, capillary and pressure forces – and in some cases inertial and elastic forces – sets the range of operating parameters in which the viscous-free surface flow of the liquid can be two-dimensional and steady, which is the desired state. To sustain the coating bead at higher substrate speeds, the gas pressure of the upstream meniscus is made lower than ambient, i.e.: a slight vacuum is applied to the upstream meniscus (Beguin, 1954).Slot coating belongs to a class of coating methods known as pre-metered coating: the thickness of the coated liquid layer is set bythe flow rate fed to the coatingFIGURE 1. Sketch of the slot-coating bead2014 Quarter 1 • 57continued on page 58 udie, and the speed of the moving substrate and is independent of other process variables. Thus, pre-metered methods are ideal for high-precision coating. However, the nature of the flow in the coating bead and, therefore, the uniformity of the liquid layer it delivers can be affected by the substrate speed, the viscosity and any non-Newtonian properties ofthe liquid, as well as the configuration of the die lips immediately upstream and downstream of the slot exit. The region in the space of operating parameters of a coating process – where the delivered liquid layer is adequately uniform – is usually referred to as a coating window. Refined flow visualization through a glass backup roll and finite-element modeling of the flow were used toanalyze the limits of operability and flow stability within those limits by Carvalho and Kheshgi (2000) and Romero,Scriven and Carvalho (2004; 2006). The failure modes (shown in Figure 2) show that the coating window is bounded by three modes of failure:High-vacuum limit: When the coated layer is thicker than the thinnest that can be produced at a fixed gap and by substrate speed (i.e.: t > t min in Figure 2), too great a vacuum at the upstreamFIGURE 2. Sketch of the slot-coating process window as a function of coating thickness, gap and vacuum pressuret continued from page 57MA TTEUCCI A W ARDSfree surface causes liquid to be drawn along the diesurface into the vacuum chamber. This diversion ofliquid destroys pre-metering.Low-vacuum limit: Too little vacuum at the upstreamfree surface leaves the net viscous drag force on theupstream part of the bead unbalanced by the pressuregradient that is imposed by capillary-pressure forcesin the menisci upstream and downstream and thedifference in external pressure on those menisci (i.e.: vacuum). As a response, the upstream meniscusshifts toward the feed slot until the bead drasticallyrearranges into a three-dimensional form thatdelivers separate rivulets to the substrate. Betweenthe rivulets are dry lanes that extend upstreamthrough the bead. Along those lanes, air is suckedinto the vacuum chamber. It is in this regime that – atgiven vacuum (ambient pressure downstream minusair pressure exerted on upstream meniscus) – there isa lower limit to the thickness of a continuous, liquidlayer that can be coated from a downstream gap ofspecified clearance. As Figure 2 shows, the limit canbe lowered by applying greater vacuum and, thereby,shifting the upstream meniscus away from the edgeof the feed slot.Low-flow limit: At a given substrate speed, toolow a flow-rate-per-unit width from the slot causes the downstream meniscus to curve so much that it cannot bridge the gap’s clearance. Consequently, the meniscus becomes progressively three-dimensional, alternate parts of it invading the gap until the bead takes a form that delivers separate rivulets or chains of droplets to the substrate moving past. This transition from a continuous, coated liquid layer is called the low-flow limit: the minimum thickness of liquid that can be deposited from a gap of specified clearance at a given substrate speed. As Figure 2 makes clear, it is independent of the vacuum applied, given that the vacuum is great enough to draw the upstream meniscus away from the feed slot.By understanding the physical mechanisms related to the low-flow limit, Carvalho and Kheshgi (2000) were able to propose a way to delay the onset of this process failure, enabling the slot-coating of thin films at high speeds. Liquid inertia was used to push the downstream meniscus such that it does not invade the coating bead, delaying the breakup into rivulets. Pilot-plant data together with the finite-element simulation in the high-speed regime is shown in Figure 3.Slot-coating of particulate suspensionsThe analysis presented considered the liquid as a Newtonian fluid. However, the liquids coated in practice are polymer solutions, particle suspensions or a combination of both. The complex flow in a coating bead may create a non-uniform particle distribution in the flow, leading to strong viscosity changes within the coating bead, which may affect process limits. Moreover, the flow may have a strong influence on the final particle distribution in the coated liquid that may be related directly to the microstructure and final product performance.Recent developments from our group have combined the solution of fluid-flow equations that considers the liquid properties as a function of the local particle concentration coupled with a particle-transport equation to study how the process parameters affect the particle distribution in the coated film. Figure 4 shows how the flow affects the particle concentration on the coated layer. Through the feed slot, the particles move from the high-shear toward the low-shear region of the flow, leading to high particle concentration in the middle of the feed slot.When the coating thickness is equal to half of the gap, the pressure gradient under the downstream die lip is negligible and the particle transport is weak, leading to a high particle concentration layer in the middle of the coated film. At lower values of the wet thickness, an adverse pressure gradient is created under the die lip. At a thickness close to one-third of the coating gap, the region of zero shear rate is located near the die lip. Particles move toward that area, leading to a high concentration near the die-lip surface and, consequently, on top of the coated film.ConclusionThe examples discussed here show how fundamental understanding of coating flows and the physical mechanisms associated with different failure modes lead to better-designed processes and can drastically reduce theprocess development and production scaleup time required to bring new FIGURE 3.

After all, most people want to enjoy themselves rather than have plenty of money without a sense of achievement and happiness.On the other hand, some people may choose a well-paid job instead of a job close to their hearts to earn more money. If one is in serious financial difficulty, one can hardly afford the luxury of a dream job.Pre-reading activities: A job-related surveyYou will find 10 typical job characteristics below, which may or may not be important to you when you choose your future job or career.

But for me, the following three factors affect my choice most. First, the job must fit my personality. I believe that certain occupations are more suitable for particular personality types than others. If the job really fits my personality, I will be more likely to be successful and enjoy working.Second, how much the job pays. It is understandable that if I want to live an adequate life, I need to make enough money to support that kind of life. Finally, the location of the office building is also an important factor in choosing a career for m e. I don’t like a job located far away from my home, because it requires extra commute time and will surely reduce the time with my family.Try to translate this letter of resignation into English.1) What did she mean in this letter?She probably meant that she would take time to truly feel thebeauty of life and the world.2) Why do you think she quitted her job?The reasons of her resignation vary. It can be caused byexcessive workload, unfair treatment or her desire forfreedom.Background InformationContinuing EducationContinuing education (similar to further education in the UnitedKingdom and Ireland) is an all- encompassing term within abroad list of post-secondary learning activities and programs. The term is used mainly in the United States and parts of Canada. Recognized forms of post-secondary learning activities within the domain include: degree credit courses by non-traditional students, non-degree career training, workforce training, formal personal enrichment courses (both on-campus and online), self-directed learning (such as through Internet interest groups, clubs or personal research activities) andexperiential learning as applied to problem solving.Experiential LearningExperiential learning is theprocess of making meaning from direct experience. It is learning through reflection on doing, which is often contrasted with rote learning(死记硬背). Experiential learning focuses on the learning process for the individual. An example of experiential learning is going to the zoo and learning through observation and interaction with the zoo environment, as opposed to reading about animals from a book. Thus, one makes discoveries and experiments with knowledge firsthand, instead of hearing or reading about others’ experiences.DiscussionHow does technology change people’s work and life?Since the dawn of time, humans have developed tools and technology to assist in the pursuit of their goals. Large shifts in technology have resulted in large shifts in social structures, and in how individuals both contribute to society and make a living. Today, advances in technology are rapidly making it possible to automate much of the work currently carried out by humans. This applies not only to blue-collar jobs through robotics and the Internet of Things, but also towhite-collar work through artificial intelligence. The wide applicability of these technologies has led to broad concern about thedestruction of jobs. Indeed, according to a 2014 Oxford study, 47% of jobs in the US could be replaced by automated processes in the next two decades. Of course, while technology has always removed the need for some types of jobs, as many havenoticed, it also creates new ones. Nine of the top ten most in-demand jobs in the latest years did not exist in 2003, suggesting that the latest technological revolution is creating new employment opportunities.On the other hand, people are working harder and are more enslaved to their work than before. More people are seen walking around with laptops or smartphones. They’re becoming slaves to high technology. So it’s not high-tech, but kind of high-shackles or high-manacles. Unfortunately, there’s no escape.How can you foster love for your work?In general, it is hard to foster love for your work, especially if you get bored with your work or if you do not feel appreciated. So if you find it hard to love what you do, there are several ways for you to develop a more positive attitude towards work. With time and effort, you may start to find that you are looking forward to work rather than dreading it.Step 1: Change the way you work. When work becomes mundane, it can feel more difficult to face. In these situations, it might be helpful to change your approach. This is sometimes called job enrichment.Step 2: Focus on the positive aspects of your job. If you are not enjoying your job, you usually tend to focus your mind on all of the negative aspects of it. To reverse the trend, you need to identify what you like about your job and start focusing on those positive aspects instead.Step 3: Practice gratitude. If you have negative thoughts about going to work each day, try keeping a list of the things that you are grateful for. Practicing gratitude can help you to feel happier overall and may also help you see your job in a more positive light.Step 4: Look at the big picture. Sometimes work may become a chore if little things start to bother you more than they should. If you find yourself focusing on minor issues at work, such as a rudecustomer or making a mistake, remind yourself that these are not important in the grand scheme of things.Step 5: Improve other parts of your life. Sometimes a job can be more difficult to engage with when other parts of your life are out of balance. Consider other aspects of your life that might be making you unhappy.New words:degrade [dɪˈɡreɪd] v. to show or treat sb in a way that makes them seem not worth any respect 降低…身份;侮辱…的人格;使受屈辱;(使)退化，降解;分解;降低，削弱(尤指质量)A dishonest action like that will degrade you.像这样不诚实的行为会使你降低身份。
