Abstract
The invention discloses a corrosion preventing method for the interior of a chimney. The surface of the inner wall of the chimney is coated with a glass fiber reinforced plastic anti-corrosion material, and therefore a glass fiber reinforced plastic anti-corrosion layer is formed. The glass fiber reinforced plastic anti-corrosion material is composed of solvent-free epoxy resin, reinforced fibers and an additive. Then, the surface of the glass fiber reinforced plastic anti-corrosion layer is coated with a nano composite material to form a surface layer, and the nano composite material is composed of resin, nanoscale ceramic powder, nanoscale quartz powder and an additive. The glass fiber reinforced plastic anti-corrosion material is creatively sprayed to the inner wall of the chimney, so that the inner wall of an original chimney is effectively prevented from being corroded, and a new glass fiber reinforced plastic inner wall is formed on the inner wall of chimney. In addition, the surface of the glass fiber reinforced plastic anti-corrosion layer is coated with the nano composite material to form the high-strength wear-resisting surface layer, and the beneficial effects of being high in seepage resistance, corrosion resistance and strength and long in service life are achieved.
Description
Technical field
The present invention relates to technical field of anticorrosion, be specifically related to a kind of chimney anticorrosion method for interior.
Background technology
The Main Function of chimney is the cigarette that puts a chimney on the stove and make the fire draw, and drains flue gas, improves burning condition.The coal unit of China all wants supporting installation flue gas desulfurization facilities, in China, coal unit desulfurization all adopts lime stone substantially, desulfurization of gypsum technology, because its carrier of this technology is exactly water and lime stone, flue gas after desulfurization temperature reduces by 45 degrees centigrade, and containing a large amount of steam and SO2, condensate water is formed at flue and chimney inside, the Main Ingredients and Appearance of condensation ice is exactly H2SO4, HC1 and other etchant gas liquid, form corrosion to chimney and flue, therefore coal unit is the problem that the most important thing need solve at desulfurization after funnel and chimney anticorrosion.
Summary of the invention
The invention provides a kind of chimney anticorrosion method for interior, to solve the problem of the chimney internal corrosion that prior art exists.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of chimney anticorrosion method for interior, by at chimney inner wall surface sprayed glass steel anti-corrosion material, thus form Corrosion Protection of Fiber Reinforced Plastics layer, reinforced plastics is by solvent-free epoxy resin, fortifying fibre and additive composition, wherein solvent-free epoxy resin mass content is 80%, the mass content of fortifying fibre is 15%, the mass content of additive is 5%, then surface layer is formed at Corrosion Protection of Fiber Reinforced Plastics layer surface coated with nano composite, nano composite material is by resin, nanometer scale ceramics powder, nanometer order quartz powder and additive composition, wherein resin content is 65%, nanometer scale ceramics powder mass content is 15%, nanometer order quartz powder mass content is 5%, the mass content of additive is 15%.
In above-mentioned reinforced plastics, fortifying fibre is alkali-free glass fibre or low density carbon fiber, and additive is curing agent and anticorrisive agent.
In above-mentioned nano composite material, additive is fire retardant and age resister.
The present invention creatively passes through sprayed glass steel anti-corrosion material at chimney inwall, not only effectively prevent the corrosion of original chimney inwall, and form new fiberglass inwall at chimney inwall, this external Corrosion Protection of Fiber Reinforced Plastics layer surface coated with nano composite, form the surface layer with this intensity high abrasion, there is high antiseepage, highly corrosion resistant, the advantage of high strength and high life, can be widely used in the anticorrosion transformation of chimney of the industries such as fire coal.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is chimney anticorrosion structure schematic diagram of the present invention.
1 chimney inwall, 2 Corrosion Protection of Fiber Reinforced Plastics layers, 3 surface layers in figure.
Detailed description of the invention
As shown in the figure, a kind of chimney anticorrosion method for interior, by at chimney inwall 1 surface spraying reinforced plastics, thus form Corrosion Protection of Fiber Reinforced Plastics layer 2, reinforced plastics is by solvent-free epoxy resin, fortifying fibre and additive composition, wherein solvent-free epoxy resin mass content is 80%, the mass content of fortifying fibre is 15%, the mass content of additive is 5%, fortifying fibre is alkali-free glass fibre or low density carbon fiber, additive is curing agent and anticorrisive agent, then surface layer 3 is formed at the surperficial coated with nano composite of Corrosion Protection of Fiber Reinforced Plastics layer 2, nano composite material is by resin, nanometer scale ceramics powder, nanometer order quartz powder and additive composition, wherein resin content is 65%, nanometer scale ceramics powder mass content is 15%, nanometer order quartz powder mass content is 5%, the mass content of additive is 15%, additive is fire retardant and age resister.
