Fluoropolymer organic lining anticorrosive material for chimney, flue and other pipelines and containers and construction method thereof

Abstract

The invention provides an anticorrosive material for a chimney, a flue and other containers and pipelines and an anticorrosive construction process. The construction method of the anticorrosive material comprises the following steps: using crude rubber with higher fluorine content as a raw material, then adding curing agent, stabilizer, special stuffing and other components, and mixing to form precuring gross rubber; dissolving the rubber by using low-molecular weight esters and ketones as the solvent to form a putty type rubber paste; and finally, adding special additives, uniformly mixing, coating to the inner walls of a chimney, a flue and a chemical container, and curing into the polymerized fluororubber organic lining under the room-temperature condition. The material can be independently used as the anticorrosive material, and can also be used for protecting common foam glass bricks (ceramic bricks) and adhesive for anticorrosive purpose in the domestic chimney (flue) at present. The invention well solves the technical problems of fluororubber room-temperature curing and difficult anticorrosive construction, can be used in a high-temperature environment of more than 230 DEG C, and can endure high-concentration sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid, hydrofluoric acid, corresponding salts and a mixture thereof. The anticorrosive lining material is economically affordable, has extremely high comprehensive anticorrosive properties such as temperature resistance, acid resistance and the like, and is applicable to the anticorrosive treatment of a cured chimney.

Description

technical field [0001] The invention relates to an anti-corrosion lining material with high temperature resistance and strong corrosion resistance and an application process. It is mainly used in the anti-corrosion of chimneys and flues after desulfurization in thermal power plants, and can also be used in containers and containers involved in petroleum, chemical and metallurgy. The anticorrosion of the inner wall of the pipeline belongs to the field of organic polymer materials. Background technique [0002] At present, there are gaps or insufficient experience in anti-corrosion measures for chimneys after desulfurization, whether in terms of chimney design, construction and other standard specifications, or in practical engineering applications. Due to investment and technical problems, the five major power plants in my country Led by the group, since the second half of 2006, 80% of the start-up projects of various power generation companies have adopted the removal of the ...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problems mentioned above in the technical application of existing fluorine rubber as anticorrosion materials, and to propose a polyfluorine organic lining anticorrosion material and construction method for chimneys, flues, other pipes and containers, which can be solved well. Fluorine rubber is difficult to construct as an anti-corrosion material. Realize that this type of material can be cured at room temperature and can be recoated many times to meet the anti-corrosion treatment needs of special fields such as chimneys and flues.
