The single largest application for reverse roll coating is applying architectural paint to coils of sheet metal; however, in the converting industry reverse roll coating is used for some thermal coatings, adhesives, color laser paper receivers, wax coatings, magnetic coatings, vinyl dispersions for wallcovering, some specialty light sensitive applications, and many specialty products that require a high precision application process. This work presents a mathematical model for the steady flow of non-isothermal, incompressible, micropolar fluid in the metering nip of a reverse roll coater with velocity slip applied at both roll’s surfaces. Lubrication approximation theory (LAT) is utilized to reduce the complexity of the non-dimensional equations. Exact solutions for pressure gradient, velocity, and temperature are achieved. At the same time, numerical techniques (Simpson’s 3/8 rule with Newton Raphson method) are used to compute the pressure distribution, coating thickness, flow rate, and separation points. Effects of coupling number, slip parameter, microrotation, and velocity ratio on velocity, pressure, temperature, and pressure gradient are presented in graphs. It is observed from the current analysis that the intrinsic rotations of the fluid particles prove to be the controlling parameter of the pressure gradient, which significantly varies the coating thickness. Also, as a result of velocity slip, the flow rate declines and the coating thickness reduces as the fluid moves faster along the boundary walls.","PeriodicalId":16823,"journal":{"name":"Journal of Plastic Film & Sheeting","volume":"50 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141192610","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Four phosphoric acid levels were used to modify PVA, resulting in four PPVA products. They were characterized using thermogravimetric analysis (TGA), water contact angle (WCA), and swelling test. PPVA-coated Mg alloys were evaluated using hydrogen evolution, cathodic polarization, electrochemical impedance spectroscopy (EIS), and scanning electron microscopy (SEM). TGA indirectly revealed crosslinked regions in the PPVA structure that increased with acid content. WCA and hydrogen evolution tests suggested that PPVA is a promising polymer for biomedical applications. Corrosion tests showed that the PPVA with 10% acid addition significantly improved the impedance modulus and lowered the cathodic kinetics compared to uncoated samples. The findings of the study suggested that the acid addition in PVA must be at least 10 % to guarantee improved corrosion resistance in HBSS, which indicates this material has potential for biological applications.","PeriodicalId":16823,"journal":{"name":"Journal of Plastic Film & Sheeting","volume":"33 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141198448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These new containers were designed to replace glass IV bottles and were quickly adopted widely for delivering medical solutions to patients throughout the world. The 40 years during which commercially available IV solutions in glass bottles were used, the healthcare industry grew dramatically with better patient outcomes while also reducing operational costs. These early developments then led to the rapid expansion of new medical devices that have been further developed to improve healthcare and reduce overall costs of the products and devices. It is not an exaggeration to suggest that the medical device industry was founded on the development of the flexible poly (vinyl chloride) (PVC) plastic IV tubing and bag. After the IV bag product lines grew to serve many markets, a new unmet need was discovered for an aseptically produced premixed drug container. This article will review how a new film was developed and used to produce the required aseptically made IV premixed drug product. It was, after the Food and Drug Administration (FDA) gave “clearance to market”, a ground-breaking product, never before thought possible for the highly FDA-regulated and controlled industry.","PeriodicalId":16823,"journal":{"name":"Journal of Plastic Film & Sheeting","volume":"33 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140006117","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
