The use of hollow sphere pigments as strength additives in paper and paperboard coatings—Part 2: Optimization in paperboard formulations for opacity and strength

This report aims to summarize the efforts in testing the properties of coatings for paperboard utilizing hollow sphere pigments (HSPs). HSPs are known to effectively scatter light and replace titanium dioxide (TiO2) in architectural coating formulations. The effect of the particle size and void fraction was evaluated, along with many coating parameters, including level of addition, binder chemistry, and blends of two HSPs. The small HSPs that have optimized voids for scattering light showed equivalent strength to the TiO2-containing control. The strength data was surprising, particularly the improvement in strength for coatings containing large particle size HSPs. Because of this increase in strength, four parts of binder could be removed, which allowed for higher brightness while not compromising other properties, including hot melt glueability. These trends held true using different binder chemistries (styrene acrylic, vinyl acrylic, and styrene butadiene). Upon refining the formulations further, blends of two HSPs showed further benefit.

An evaluation of alternative coating material laminated marble in Turkey

The natural stones stand at a significant point of human life from the existence of human-life to present time with their durable and persistent features. They have been used as an important construction material until the recent past. Although the production of marble material is widespread in Turkey, the conversion to the final case marble material is not observed prevalently. The aim of this study, the evaluation of the laminated marble material in terms of being used in architecture and the types of the advantages presented by the material are all listed at the end of the research. The results obtained from the architectural coating application carried out to examine the preferable reasons between marble and laminated marble are thought to have advantages in terms of flawless connection details, easy application, transportation and storage processes in comparison to the marble material for the case of coating surfaces with similar quality. The laminated marble material is more durable by the effect of 9 mm porcelain ceramic at the bottom than the traditional marble plate of 3 mm thickness and is nearly 50% lighter than the marble material having the same thickness and sizes with the laminated marble material that is clear that nearly 50% decrease in transportation costs will be expected. When viewed from this aspect, the new construction materials obtained by reconsidering and re-developing the natural materials in accompany with the innovativetechnological methods will contribute easy and eco-friendly to the architectural design-application projects especially in terms of easy application and utilization.

Transferring cognitive apprenticeship to manufacturing process knowledge management system

Purpose – This study aims to develop a manufacturing process management system which aims to benefit the excavation, collection and search of the mentors’ experience and knowledge. The coating painting industry is a typical small and medium-sized traditional industry and usually depends on master's experience to solve the manufacturing problem. Design/methodology/approach – Based on the characteristics and manufacturing process of the architectural coating industry, this study develops a practical knowledge management system (KMS) with two stages. The first stage collects and analyzes manufacturing process data, and the second stage constructs the KMS of the manufacturing process. Findings – This manufacturing process KMS can accumulate and share the operators’ experience and knowledge systematically; this KMS not only improves the apprentices’ skill and problem-solving abilities but also enhances the enterprise’s overall product quality, undoubtedly. Research limitations/implications – This manufacturing process KMS was designed to be implemented in architectural coating industry which is defined as a “3K” industry. Such a specific manufacturing process KMS is not a generalized principles system which is hard to apply to other industries because the different industries own different explicit and tacit knowledge which cannot be captured in this study simultaneously. Further research will try to design a more complete and integrated KMS for industry and combine it with other approaches such as TRIZ (Russian acronym for the theory of inventive problem solving), patent database and problem-solving tools. Practical implications – The developments of this manufacturing process KMS software was based on systematic analysis and design. Using the architectural coating industry as an example, this system externalized the cognitive apprenticeship and developed a KMS based on the characteristics of the manufacturing process to preserve and share the valuable manufacturing process knowledge. Originality/value – The paper extends knowledge management’s contribution to externalize the cognitive apprenticeship and develop a KMS. The adoption of this manufacturing process KMS enables employees to improve their techniques, skills and problem-solving abilities and enables companies to enhance the overall product quality.
