Abstract

In the paper industry, the drying process is the second most energy consuming process after the pulping process; it accounts for around 35% of the total energy consumption. If energy consumption in the drying process can be reduced, the cost of paper production would be decreased considerably. The more recent and wide acceptance of the use of infrared energy for the drying of coated grades has led to many developments and improvements in materials and controls, making IR a practical and safe method for the paper industry. This process is mainly based on the absorption of infrared radiation by paper coatings. IR drying directly affects both the time of drying and the rate of drying. With infrared drying, the time of drying can be reduced, which directly influences the economics of the paper production.

In this study, we tried to study the borates as borates absorb the infrared radiation at a maximum level at wavelengths of 2-3 μm, which is similar to water absorbency. The objective of this study was to investigate the influence of borates on the infrared drying of paper coatings. Also at the same time the bulking effect of Borates on paper coatings was studied.
