Slot Die

Slot-die coatings are advantageous when used for coating large-area flexible devices; in particular, the coating width can be controlled and simultaneous multi-layer coatings can be processed. To date, the effects of ink widening and the coating gap on the coating thickness have only been considered in a few studies. To this end, we developed two mathematical models to accurately estimate the coating width and thickness that consider these two effects. We used root mean square deviation (RMSD) to experimentally verify the developed method. When the coating gap was increased, the coating width increased and the coating thickness decreased. Experimental results showed that the estimated performances of the coating width and thickness models were as high as 98.46% and 95.8%, respectively. We think that the developed models can be useful for determining the coating conditions according to the ink properties to coat a functional layer with user-defined widths and thicknesses in both lab- and industrial-scale roll-to-roll slot-die coating processes.

Slot-die coatings are advantageous when used for coating large-area flexible devices; in particular, the coating width can be controlled, and simultaneous multi-layer coatings can be processed. Till date, the effects of ink widening and coating gap on the coating thickness have only been considered in a few studies. To this end, we developed two mathematical models to accurately estimate the coating width and thickness considering these two effects. We used root mean square deviation (RMSD) to experimentally verify the developed method. The coating width was seen to increase and the coating thickness was seen to decrease when the coating gap was increased. Experimental results showed that the estimation performances of the coating width and thickness models were as high as 98.46 % and 95.8 %, respectively. We believe that the developed models can be useful for determining the coating conditions according to the ink properties to coat a functional layer with user-defined widths and thicknesses in both lab- and industrial-scale roll-to-roll slot-die coating processes.

Companies must be responsive in addressing consumer behavior by anticipating changes and retaining consumers so that consumers are loyal. The aim of this research was to determine the effect of products and prices on consumer’s purchasing decisions Mamasuka spacy flour at PT Jico Agung in Pekanbaru. There were 60 consumers used as population and sample in this research. They are the consumers from shops and grocers selling Mamasuka spicy flour of PT Jico Agung in Pekanbaru. While the method used in this research was multiple linear analysis. The result showed that both products and prices affected each other in consumers’ decision to buy Mamasuka spicy flour. Product and prices also affected positively consumers’ purchasing decision in buying Mamasuka spicy flour at PT Jico Agung in Pekanbaru. The contribution of product and prices to consumers’ purchasing decisions in buying Mamasuka was 41,6%, while the rest is equal to 58,4% influenced by other variables not examined in this research. PT Jico Agung was expected to improve product quality and provide competitive price as well as concern about promotion strategi used.Keywords: Products, Prices, Purchasing Decisions
