Glass flake epoxy paint, glass flake paint on desulfurization equipment used more often, early foreign chimney has applications are now less used. No domestic chimney applications. 2.3.6 anti-corrosion coating layer material pouring acid + 1) anti-corrosion coating layer, acid pouring steel inner cylinder surface material before brushing anticorrosive coating layer plus pour pouring acid material, within the general configuration pouring acid material layer and the inner cylinder with steel link steel mesh. Anticorrosive coating layer is OM Ⅰ type anti-corrosion coatings. Pouring acid resistant materials generally have acid resistant concrete, mortar acid potassium silicate layer 2) anti-corrosion coating layer, acid corrosion material pouring this scenario, construction conditions corrosion lining of poor quality control difficult. And high anti-corrosion lining design requirements, can not produce fine cracks penetrate chimney flue to prevent steel corrosion within the cylinder. Multi-tubular steel inner cylinder chimneys, steel corrosion within the cylinder liner pouring investment scheme lowest multi-tubular steel inner cylinder chimney program. Due to the inevitable anti-corrosion lining smoke corrosion, such steel chimney need regular repair and maintenance of the inner cylinder. According to Japan's experience, generally more than ten years on the need for re-corrosion lining repair and construction. 3) anti-corrosion coating layer, acid pouring material lining structure
