Description

A kind of preparation method for heat-engine plant desulfurized chimney lining anti-corrosion silicone sealants
Technical field
It is specially a kind of for heat-engine plant desulfurized chimney lining anti-corrosion silicone sealants the invention belongs to chemical field Preparation method.
Background technology
Contain substantial amounts of dust, SO in the flue gas of coal-fired power plant's discharge2、NOxDeng pollutant, wherein SO2Be PM2.5 and The primary pollution source of acid rain, the health of the mankind is severely compromised, with the implementation of national new environmental protection policy, newly-built and existing thermoelectricity Factory will carry out flue gas desulfurization, and wet method limestone desulfurization technique is occupied an leading position in thermal power plants exhaust gas cleaner. Flue gas is after desulfurization, although the SO in flue gas2Content greatly reduce, still, the method for washing is a small amount of in flue gas to removing SO3Effect is simultaneously bad.Due to being reduced through wet desulphurization, smoke moisture increase, temperature, flue gas is easily in the inwall knot of chimney Reveal, remaining SO in flue gas3After dissolving, the very strong dilute sulfuric acid solution of corrosivity is formed, in the coagulation that surface is formed, in chimney Lining construction material has very strong aggressivity, therefore to maintain the normal operation of power plant, must be requested that inner lining material has anti-strong Acid corrosion ability；On the other hand, chimney running environment is complicated, and flue gas difference variation is big, under normal operation, after wet desulphurization Flue-gas temperature between 40-80 DEG C, desulphurization system overhaul or do not run and under unit operation operating mode, flue-gas temperature in chimney More than 200 DEG C are may be up between 130-150 DEG C, when breaking down, therefore it is required that liner has Anti-temperature difference changing capability, in temperature Degree change is not ftractureed in environment frequently and durable, meets that two aspect performances are most important to inner lining material.
Deng Yu is strong et al., and the patent CN201210284643.4 delivered provides a kind of Desulfurization chimney anticorrosive paint method, its group Dissolve, disperse by a certain percentage with solvent, filler and auxiliary agent as fluoroelastomer, mix after be used as component A, curing agent and solvent By a certain percentage mix after be used as B component, after A and B component are stirred in proportion obtain anticorrosive paint, excellent performance, but into This is higher, promotes limited；The patent CN201310362114.6 of Lei Mu lifes et al. describes one kind to be prevented for desulfuration chimney inwall Rotten organic silicon adhesive, acid resistance is good, but its hardening time is longer, and workability is bad；The patent of Zhao's generation fine jade et al. CN201310047939.9 describes a kind of chimney anticorrosion dual-component polyurethane adhesive, has adhesive strength height, solidfied material Good toughness, excellent acid resistance is feature, but high/low temperature alternation performance is up for improving；Patent 201010290484.X is introduced A kind of anti-corrosion organosilicon coating, can with resistance to 350 DEG C of high temperature and also antiseptic property it is excellent, but because silicones hardness is higher, And need to be heating and curing that the construction environment and condition of cure of inner wall of stack obviously can not be met.
