Abstract
Chemical Resistant Masonry exhibits excellent resistance to a broad range of corrosive chemical environments, such as dilute or concentrated acids, solvents, or alkalies. Chemical Resistant Masonry can withstand high temperatures that are beyond the limits of most common materials. No other material provides the superior chemical resistance and high thermal stability provided by chemical resistant masonry.
Chemical Resistant Masonry itself is not a complete liquid barrier and is part of a three component system which includes brick, mortar, and membrane Many different plastic membranes are used beneath brickwork to protect a substrate from corrosive service conditions. In severe environments, such as strong acids, solvents, or alkalies at elevated temperatures, a Fluoropolymer plastic membrane coating or lining system protected with chemical resistant brick and mortar may be the only practical solution to these aggressive conditions. Even costly alloys can not always withstand such exposures. Some typical chemical resistant masonry applications where plastic membrane would be used include reactor vessels, process tanks, scrubbers, columns, incineration equipment, and quench vessels.
The objective of this paper is to highlight high temperature and corrosive applications for fluoropolymer plastic materials of construction as a component of a Chemical Resistant Masonry System.
