Description

A kind of refractory ceramics composite material of thermal power plant flue coating and using method
Technical field
The invention belongs to refractory ceramics composite material technical field, and in particular to a kind of thermal power plant flue coating Refractory ceramics composite material and using method.
Background technology
Power plant desulphurization system uses one gypsum wet sulfur removal technology of limestone, most of flue also not to take anti-corrosion to arrange at present Apply, but put into operation the growth of time due to power plant, ageing equipment, desulphurization system efficiency, the sulphur content that flue gas is contained within can be Because temperature reduces after desulfurizing tower, combined with condensate and become dilute sulfuric acid, so as to boiler flue corrosion will be leaked quickly, due to flue Interior with high temperature, and with certain shock conditions, so the anti-corrosion material glass flake that power plant field uses is not applied to.
Content of the invention
It is an object of the invention to solving above-mentioned technical problem and providing a kind of height of thermal power plant flue coating Warm ceramic composite and using method.
For achieving the above object, the present invention is adopted the following technical scheme that:
A kind of refractory ceramics composite material of thermal power plant flue coating, including epoxy resin and is evenly mixed in institute Material of main part in the epoxy resin that states, both mass fraction ratios are 4-5:1.
Described material of main part is made up of the component of following mass fraction:
Multifunctional (+)-2,3-Epoxy-1-propanol type epoxy resin of the described epoxy resin for high-temperature-resistant epoxy resin containing heterocycle structure, type Number 6155G, 280 DEG C of heatproof.
In the material of main part, the particle diameter of each several part is Brown Alundum 2-3mm and/or 0.1-0.5mm, SiC l-2mm, Si02 2-7 μm, 2-4 μm of asbestos wool, glass fiber 10-15mm.
Asbestos wool, playing in whole material improves the associativity of resin and high-abrasive material, consolidates wear-resistant material, increases overall Wearability, and improve because abrasion resistant particles density is more than resin, cause deployed material to stand and occur resin with The detached situation of abrasion resistant particles.
Glass fiber, it is inconsistent with the coefficient of expansion of steel pipe to play a part of mainly to solve resin, causes in temperature In the case that change is excessive, steel pipe is declined with being firmly combined with property of material, increased glass fiber, is increased equal in high-abrasive material Add telescopic connect band, can thus solve the situation that the bond strength produced by temperature change declines.
The present invention also aims to providing a kind of making for refractory ceramics composite material of thermal power plant flue coating With method, comprise the following steps:
The epoxy resin of material of main part and firming agent are blended with by 5:4-3:1 ratio is stirred;
It is applied in the flue inner wall for needing to repair, in 3-8mm, 20 DEG C of solidification 3-4 are little for ambient temperature for coating thickness When can meet equipment and normally run intensity.
Described firming agent is phenolic aldehyde amine curing agent or polyester amine.
Compared with prior art, the invention has the beneficial effects as follows:
The excellent wearability of the existing pottery of refractory ceramics composite material of the invention and corrosion resistance, have macromolecular material again Elasticity, toughness, while the characteristic also having not available for other common materials, the such as compatibility with other materials is general Property, and be firmly combined with, composite structural strength height (>=15MPa), can have with join protection and the material that replaces:Metal material, modeling Material, pottery, rubber, concrete etc..
Specific embodiment
Below, the substantive distinguishing features of the present invention and advantage are further described in conjunction with example, but the present invention not office It is limited to listed embodiment.
Embodiment:The refractory ceramics composite material of thermal power plant flue coating, see the table below:
In the material of main part, the particle diameter of each several part is Brown Alundum 2-3mm and/or 0.1-0.5mm, SiC l-2mm, Si02 2-7 μm, 2-4 μm of asbestos wool, glass fiber 10-15mm.
Wherein, Brown Alundum can be the mixing that particle diameter is two kinds of 2-3mm and 0.1-0.5mm, or one kind therein, when When the Brown Alundum of two kinds of particle diameters mixes, the mixing quality ratio of the Brown Alundum of two kinds of particle diameters is 1:1 or 1:2 (big particle diameter and granules The mixing quality ratio in footpath).
In concrete preparation, it is mixed and stirred for uniformly with epoxy resin after each material of main part component of above-mentioned quality is weighed , mixed epoxy resin room temperature, sealing, shading storage, because certain anti-corrosion that inherently has of epoxy resin is imitated Really, while these powder or granule for adding all are wear-resistant anticorrosive materials, the antiseptic effect that can be effectively ensured after coating, epoxy Resin also plays the effect of these materials that bond.
In Specific construction, the epoxy resin of material of main part and firming agent is blended with according to 3:1 or 5:4 ratio is carried out Stirring, is then applied in the flue inner wall for needing to repair, and coating thickness is in 3-8mm, 20 DEG C of primary solidifications of ambient temperature Time at 3 hours, general 4 as a child after normally can run, be fully cured needs 24 hours.
Wherein, firming agent is exactly to arrange in pairs or groups a kind of material of epoxy resin, makes epoxy resin cure into solid-state.Described solidification Agent is to drink autonomous limb class firming agent, such as T-31 resistances to water or poly- meal with wine limb class, such as 203.
The ceramic composite of the present invention, is a kind of unique NEW TYPE OF COMPOSITE surfacing, excellent wear-resisting of existing pottery Property and corrosion resistance, have elasticity, the toughness of macromolecular material again, at the same also have other common materials not available for characteristic, Compatibility such as with other materials, versatility, and be firmly combined with, composite structural strength height (>=15MPa) can be with join protection Have with the material that replaces:Metal material, plastics, pottery, rubber, concrete etc..
Meanwhile, as high-load high-abrasive material coating, it is the non-metal solid microgranule high polymer of 100% solidification, is non- Contractility material, has certain toughness, and its characteristic of expanding with heat and contract with cold is combined fine and close steady in -10-100 DEG C of interval with metal surface Fixed.For protecting metal surface easy to wear, minimum thickness is 3 millimeters, it is adaptable to which abrasion of particles is serious, coating layer thickness is had will The metal surface that asks.
Very high to desulfurization industry requirement for Environmental Protection in China situation, if desulfurization does not come into operation, shutdown process can only be carried out, Large power plant shuts down direct economic loss every time up to more than million.
The anti-corrosion material convenient construction of the present invention, advantage are that on-site procedure for repairing operation is simple, hardening time is short, use effect Fruit is well, low to oneself damage flue prescription, can achieve quick reparation and simultaneously comes into operation rapidly.Repair process is simple, pottery Anti-corrosion material is directly applied to flue inner wall after proportioning mixing.But when will smear if for embodying optimum efficiency Pat material, prevent from producing bubble in material, applying material want thickness uniformly, transitions smooth.Hardening time is short:Ambient temperature exists When 20 DEG C, solidification 4 hours can normal operation input.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
