▎ 摘　　要

NOVELTY - A repairing agent includes multi-layer composite coating comprising wear-resistant layer, bonding layer, and anticorrosive layer which are sequentially coated on inner wall of desulfurization tower from top to bottom, and anticorrosive layer closely attached to inner wall of desulfurization tower, where the total thickness of repair agent is 1.8-2.5 mm, the thickness of wear-resistant layer is 0.5-0.6 mm, the thickness of bonding layer is 1-1.5 mm, and the thickness of anticorrosive layer is 0.3-0.4 mm. USE - Repairing agent for boiler flue gas desulfurization tower. ADVANTAGE - Since the repairing agent forms composite coating structure with outer layer of wear-resistant layer and inner layer of anticorrosive layer, and each coating forms interpenetrating network structure during the curing process, so that all raw materials have synergistic effect, and effectively improves wear resistance, anticorrosive performance, and meets the requirements. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of repairing agent for boiler flue gas desulfurization tower.
