“…Similar commercial processes involving flammable materials and very high-applied voltages in the range of 50-150 kV, such as the well-established industrial process flocking and the use of electrostatic hand-held spraying equipment, have been surveyed. 168 The safety standard for this process on a small scale has been established by the European industry since 1994 and has been consistently revised and updated four times from 1994 to 2011. 169,170 Furthermore, the safety aspects of routine maintenance of charged equipment during a continuous manufacturing process need to be investigated.…”

Academic and industrial research on nanofibres is an area of increasing global interest, as seen in the continuously multiplying number of research papers and patents and the broadening range of chemical, medical, electrical and environmental applications. This in turn expands the size of the market opportunity and is reflected in the significant rise of entrepreneurial activities and investments in the field. Electrospinning is probably the most researched top-down method to form nanofibres from a remarkable range of organic and inorganic materials. It is well known and discussed in many comprehensive studies, so why this review? As we read about yet another "novel" method producing multifunctional nanomaterials in grams or milligrams in the laboratory, there is hardly any research addressing how these methods can be safely, consistently and cost-effectively up-scaled. Despite two decades of governmental and private investment, the productivity of nanofibre forming methods is still struggling to meet the increasing demand. This hinders the further integration of nanofibres into practical large-scale applications and limits current uses to niche-markets. Looking into history, this large gap between supply and demand of synthetic fibres was seen and addressed in conventional textile production a century ago. The remarkable achievement was accomplished via extensive collaborative research between academia and industry, applying ingenious solutions and technological convergence from polymer chemistry, physical chemistry, materials science and engineering disciplines. Looking into the present, current advances in electrospinning and nanofibre production are showing similar interdisciplinary technological convergence, and knowledge of industrial textile processing is being combined with new developments in nanofibre forming methods. Moreover, many important parameters in electrospinning and nanofibre spinning methods overlap parameters extensively studied in industrial fibre processing. Thus, this review combines interdisciplinary knowledge from the academia and industry to facilitate technological convergence and offers insight for upscaling electrospinning and nanofibre production. It will examine advances in electrospinning within a framework of large-scale fibre production as well as alternative nanofibre forming methods, providing a comprehensive comparison of conventional and contemporary fibre forming technologies. This study intends to stimulate interest in addressing the issue of scale-up alongside novel developments and applications in nanofibre research.

“…An electrostatic spark could be the cause of such an accident. However, surprisingly, few studies have been conducted on electrostatic hazards involving spraying and/or liquid leakage (Finke, 1989;Kr€ amer, 1993;Kr€ amer & Fr€ ochtenigt, 1993;Matsui & Ohtsuka, 1999;Post, Glor, L€ uttgens, & Maurer, 1989;Walmsley & Mills, 1992). To prevent such accidents, more quantitative research into the electrostatic hazards of spraying and/or liquid leakage will be necessary to assess such hazards in an industrial process under various conditions and to propose effective countermeasures.…”

“…oven temperature, curing time, and conductivity, as well as powder yield, have a significant impact on the quality of the paint coating. After selecting the optimal values for the given parameters, it is possible to obtain an average coating thickness (about 80 microns) (Adams, 1989;Boer, Petruta, 2014;John, 2015;Kramer, 1993). The coatings, in particular thermally cured, phenolic or epoxy phenolic, provide corrosion resistance, and the heat-curing coating to protect against corrosion must be stable at elevated temperatures of up to 220°C.…”

Identification of causes of incompatibilities of the products treated with the powder method allows their elimination or minimization of those differences, which contributes to the improvement of the powder coating method and thus to the development of processes in the field of metallurgy. The aim of the article is to analyze the corrosion problem on the ventilator cover with the use of the sequence of selected quality management instruments (Ishikawa diagram and the 5Why method) and proposed actions to eliminate or minimize the problem and improve the powder coating process and organization within the workplace place of the selected company. The analysis was carried out at the request of the management of the Podkarpackie fan producer. The management wanted to analyze some of a problems in the simple and cheaper way, and thus in the enterprise this using the types of the method was not practiced. The management were wanted to analyze the problem with using these types of method because, in this enterprise, this was not practiced yet. The analysis of corrosion using the new sequence – Ishikawa diagram and 5Why method allowed, i.e.: appropriate analysis of the problem, identified the root cause of adequate problem and proposed the actions for the problem, thanks to which is possible to improve the powder coating process and a good organization workplace in the selected company. The sequence used and the proposed improvement actions can be used to analyze quality problems in other production and service companies.
