Technical field
The present invention relates to high temperature resistant, as to be able to bear strong corrosion environment corrosion-resistant lining material and application art, be mainly used in later chimney of fuel-burning power plant desulfurization and flue anticorrosion on, it is anticorrosion also to can be used for simultaneously oil, chemical industry and metallurgical related container and inner-walls of duct, belongs to the organic polymer material field.
Background technology
Present anticorrosive measure at the desulfurization after-funnel, no matter design at chimney, standard specifications aspects such as construction, still on the engineering practical application, all exist blank or do not have enough experiences, because investment and technical problem, headed by China's five big Power Group, each tame genco is since the second half year in 2006,80% startup project has all taked to remove smoke heat replacing device (GGH), so, the minimum exhaust temperature of flue gas is between 40～50 ℃, and flue gas system (FGD) when stopping transport in line temperature reach more than 130 ℃, so chimney must carry out rotproofing.
At present, the chimney anticorrosion technology mainly contains foam glass brick technology, VP technology, glass flake and improved technique, acid resistant adhesive mortar, alloy lining technology etc.And Chinese quality product and technology that is that all right is ripe, comparatively ripe and good market prospect all be foreign technology, but this series products price is higher, exceeds user's ability to bear.
Viton is a kind of synthetic elastomer that is connected with the extremely strong fluorine atom of electronegativity on the carbon atom on the main chain.Because C-F bond energy big (485kg/mol), and the fluorine atom covalent radius only has C-C bond distance half, 0.064nm, therefore fluorine atom can well shield the C-C key get up, guaranteed the stability of main chain C-C key, made it have the incomparable oil resistant of other rubber, chemically-resistant, physical and mechanical properties and weathering resistance, electrical insulating property and radiation resistance.
Viton is a kind of multiduty specialty elastomer, it is widely used in fields such as space flight, aviation, automobile, oil, chemical industry, machinery, traffic and household electrical appliances, obtain the approval of many industries, only had a few countries such as the U.S., Japan, Italy, Germany, Belgium, China and Russia to produce in the world.
Viton specific molecule structures shape its have outstanding heatproof and chemical mediator-resitant property, be a kind of good impregnating material.But the viton product that uses all needs baking now, need use the binding agent paving when doing impregnating material usually.And the performance of present binding agent heatproof and resistant to chemical media is more very different than the performance of viton itself, will hand over seam crossing to stay weak link at offset plate and offset plate like this.Also have some binding agent to contain solvent, behind the paving viton plate, solvent can't normally be discharged, and the big area paving is very easily bubbled adhering to of influence and substrate.These factors have all restricted viton as the application of impregnating material at some special dimensions, in the chimney anticorrosion as the fuel-burning power plant mentioned in front, in oil, chemical industry and metallurgical related container and inner-walls of duct are anticorrosion.
In addition, the fluorine carbon coating of use on the steel construction surface is arranged at present, it does not need caking agent, but this coating solid content is little, low and the interval recoat poor performance of one-pass film-forming thickness, and heat resistance is poor, can not satisfy the chimney anticorrosion in fuel-burning power plant, or in oil, chemical industry and metallurgical related container and the requirement of inner-walls of duct rot-resistant.
Summary of the invention
The objective of the invention is to be applied in as impregnating material the problems referred to above of technical existence at existing viton, the poly-fluoropolymer organic lining anticorrosive material and the constructional method of a kind of chimney, flue and other pipeline and container are proposed, solve viton well as the big problem of impregnating material difficulty of construction, realize such material ambient cure and recoat repeatedly, satisfy special dimensions such as chimney and flue the rotproofing needs.
The technical solution used in the present invention is as follows:
The chimney that the present invention proposes and the inside lining anti-corrosive material of flue are A, B two-component materials.
Wherein the A component is that the high fluorine-containing rubber of employing is a raw material, and components such as adding vulcanizing agent, stablizer and reinforcing filler carry out mixing back and form putty type rubber cement with solvent, and adding special type filler and special addition agent are made in putty type rubber cement again.
The B component is additive and organic solvent.
After A, B component mix, be coated with and be contained in chimney, flue and pressure vessels for the chemical industry inwall, solidify at ambient temperature and can form polyfluorine rubber organic lining.
This material can independently use as impregnating material, also can protect anticorrosion conventional foam plate glass of present chimney (flue) (ceramic tile) and binding agent.Because traditional binding agent is a silastic material; acid resistance is relatively poor; the fragment of brick heat-shock resistance is poor; the harsh corrosion working condition that all can not adapt to Chinese desulfurization after-funnel; necessary consideration is more outstanding in external coating one deck comprehensive anticorrosive performance, and the material of actual working conditions is protected after the desulfurization of adaptation China.
Below the composition of above-mentioned inside lining anti-corrosive material is elaborated:
1, the rubber unvulcanizate of A component:

| Title material | Rubber | Stablizer | Reinforcing filler | Vulcanizing agent | Remarks |
| Parts by weight | 100 | 5-40 | 3-50 | 1-15 |
Because viton mooney viscosity height, the molecular chain rigidity is big, and plastication is not obvious, so rubber unvulcanizate selects mill directly to carry out mixing when producing.The viton poor thermal conductivity, mixing living heat is big, and particularly when reinforced additive was selected carbon black for use, when the carbon black add-on was big, living heat was bigger.Along with the rising of melting temperature, cause sizing material roll banding and incipient scorch easily, for this reason, must strengthen the cooling of mixing process, guarantee that preferably glue furnacing temperature remains on below 60 ℃.The control of refining glue amount is as follows:
150mm (6in) rubber mixing machine per car dress glue amount is no more than 1kg, and 230mm (9in) rubber mixing machine should be controlled at 3kg, and 360mm (14in) rubber mixing machine is 5～9kg.

Further, the additive of B component also can comprise organo-peroxide (as methylethyl ketone peroxide, benzoyl peroxide), and in 100 parts of other weight of additive umbers, the add-on of organo-peroxide is 100-300 part.
Organic amine, silane coupling agent and solvent types selection and add-on are extremely important to poly-fluoropolymer organic lining anticorrosive material in the B component, are the keys that realizes the material ambient cure.Organic amine and silane coupling agent select improper this material that may cause can not solidify at normal temperatures at all, what of add-on then can directly have influence on the over-all properties after the material cured, add-on meeting bigger than normal makes that heat resistance and elasticity obviously descend after the material cured, and material is hard and crisp.The speed and the surface drying time of the evaporation rate of choice of Solvent decision coating internal solvent, the then short meeting formation of the surface drying time coatingsurface defective of volatilizing too soon as pin hole, also can increase difficulty of construction simultaneously; Volatilization has then prolonged the set time of material too slowly, easily forms sagging.According to material environment for use (mainly being the temperature and humidity environment), the selectivity of superoxide adds can improve the adaptive faculty of this material to temperature.
Compared with prior art, technological core of the present invention is selection, special type filler and special addition agent selection and add-on and the selection of B component effective constituent kind and the add-on of viton kind in the A component preparation process.The selection of viton kind is improper, and the heatproof of final material, acidproof, heat shock resistance and adhesion property do not reach desulfurization after-funnel or flue requirement of actual working condition.The adding of special type filler and special addition agent is a material interval recoat performance generation qualitative leap key, and add-on meeting bigger than normal causes material hardens, and elasticity reduces, and add-on is on the low side then not to reach raising recoat performance at interval at all.
5, the construction technology of poly-fluoropolymer organic lining anticorrosive material
The construction technology of gathering on the chimney anticorrosion after the fluorine organic materials is applied in desulfurization is as follows:
(1) after finishing the installation of preparation of construction and operation platform, at first inner wall of stack is carried out base treatment, be high pressure water washing or mechanical ashing, to sanding inject process or wet method sanding inject process surface that steel base then adopts metal, metal finishing reaches the Sa2.5-3 level.
(2) levelling is handled, and carries out levelling more than the concavo-convex 6-8mm of reaching and handles, and material therefor is potassium silicate acid resistant adhesive mortar, water glass acid resistant adhesive mortar, resin-bonded mastic, silicon rubber or fluororubber material, and opposite joint is repaired simultaneously, sees just to stitch and mends.
(4) will gather fluorine organic materials A, B component and mix after, blade coating or spray to inner wall of stack, wet-film thickness is controlled at 0.3-3mm, the surface is smooth substantially, temperature is more than 10 ℃, humidity is below 85%;
(5) maintenance: room temperature: 1-3 days, or heat: after 50-80 ℃ of maintenance 3-8 hour, again at 100-150 ℃ of maintenance 12-48 hour.
The special stable structure of viton determines such material to have good heatproof, antiseptic property such as acidproof.But traditional mode is earlier with its high temperature vulcanized rubber plate that is prepared into, paste then, common heatproof of binding agent and acid resistance can not satisfy domestic desulfurization after-funnel or there is high temperature simultaneously in flue, acidic medium, the fluctuation of cigarette temperature causes actual working conditions such as thermal stresses and acidic medium change in concentration greatly.Simultaneously, existing other purposes fluorine coating are except heat resistance has much room for improvement, because the viton structure is too stable, in a single day coating solidifies, and common solvent all can not be dissolved it, and same material is recoat at interval, can only an application, it is low to add solid content, and one-pass film-forming thickness is minimum, can not satisfy the uneven requirement to application thickness of chimney or flue block substrate at all.The present invention passes through to adopt the two components of A, B, and adds special type filler and special addition agent in the A component, and the solidifying agent kind of selecting the B component cleverly, solves the world of self-vulcanizing and interval recoat, domestic technical barrier well.
