Abstract
Description
Technical areas:
[0001] The invention relates to a method for preparing a composite material, in particular to a method for preparing a composite material that is resistant to corrosion by concentrated acid and acidic flue gas at normal or high temperatures. Background technique:
[0002] At present, general synthetic resin-based composite materials such as epoxy FRP, unsaturated polyester FRP, phenolic FRP, furan FRP, and inorganic FRP such as magnesite FRP are not resistant to concentrated acids, especially high-temperature concentrated acids (such as 98°C at 100°C). % sulfuric acid, 97% nitric acid at 100°C); and the anti-corrosion methods in concentrated acid media currently mainly use ceramic tile linings, lead plate linings, acid-resistant mortar linings and other methods that are heavy, difficult to construct, and expensive, or use Low carbon stainless steel, duplex stainless steel, titanium alloy, nickel alloy and other expensive alloy materials are used to make equi...
