Thermal Spray Applications in the Paper Production Industry
Thermal spray coatings, along with certain proprietary sealants, are widely used in the paper manufacturing industry for corrosion and wear resistance and to impart special surface characteristics. This article discusses the steps involved in the paper manufacturing process. Most modern papermaking machines are based on variations of the Fourdrinier machine. The article describes four operational sections of the machine: forming, press, drying, and calendar. It provides an overview of the machine components where thermal spray coatings are used, namely digesters, blow tanks, suction roll, center press rolls, yankee dryer rolls, calendar rolls, doctor/scalping blades, and cutting equipment.
