Abstract
The invention relates to a concrete-based element mixing body which comprises a concrete-based lining layer, a reducing agent, a reinforcing agent, a restoration agent, a toughening agent and a glazing agent, wherein the reducing agent, the reinforcing agent, the restoration agent and the toughening agent are seeped into the deep surface layer of the concrete-based lining layer to form a concrete-based main body, and the glazing agent is coated on the surface of the concrete-based main body. The whole anti-corrosion layer is an element mixing body which is formed by the affinity of a main body that integrates reduction, reinforcement, restoration and toughening into a whole and a glazing protection reinforcing face, and a chemical molecule chain structure body with seepage, temperature, acid, corrosion, stretching and cold and heat impact resistance is formed, therefore, the main body has the same corrosion resistance efficacy even if the glazing protection reinforcing face is damaged. The concrete-base element mixing body can be applied to chimneys, flues and cement ponds of a power plant.
Description
Technical field
The present invention relates to anticorrosion, waterproofing materials, especially a kind of concrete base-based element mixing body as chimney anticorrosion, waterproof.
Background technology
Anticorrosion both at home and abroad in the past all is to be reproduced an anticorrosive coat by anticorrosion basal plane, owing to being constructed, the restriction of material, anticorrosive coat and basal plane do not have intimate combination, can not form one, can drum, crackle occur, come off, cause the anticorrosive coat anti-corrosion function to disappear, and protocorm does not have antiseptic effect, causes the corrosion Frequent Accidents.
Especially need the anticorrosion of desulfuration chimney in chimney of electric plant, flue, pond etc., because anticorrosion flue gas corrosion grade is severe corrosive, the type of flue gas corrosion comprises sulfuric acid, chloric acid, hydrochloric acid, nitric acid, hydrogen chloride etc., and the temperature of flue gas is very high.Flue gas after desulfurization is processed generally also contains hydrogen fluoride and chloride etc., and they are that corrosion strength is high, permeability strong and the difficult low temperature and high relative humidity diluted acid type material of taking precautions against.Flue gas after desulfurization environment become low temperature, high humidity, smoke density increases, and chimney reduces from pull out force, and the flue gas pressures in the chimney raises, and has increased the weight of flue gas and has contained acid solution moisture to the infiltration of outer tube wall direction.
On market, much all adopt interior being lining with at present and add one deck corrosion-resistant material, such as liner abros plate, titanium plate alloy sheets, liner foamed glass brick, inside lining anti-corrosive VP plate etc., but the anti-corrosion material resistance to elevated temperatures that these schemes are made is poor, can not bear high-temperature flue gas, can not bear the alternation of high-temperature flue gas and low-temperature flue gas, anticorrosive coat also easily occurs and peels off, therefore can not well solve the problem of corrosion, and such method can not play good effect to waterproof.
Summary of the invention
The object of the present invention is to provide a kind of concrete base-based element mixing body of corrosion-resistant, high temperature resistant while waterproof, thereby solve desulfuration chimney burn into seepage, guarantee the chimney lining design service life.
For realizing that the present invention transform the logical inner liner of the original concrete kip of chimney as with superpower preservative efficacy based element mixing body by reactions such as chemistry, physics.
The logical inner liner of original concrete kip is that undressed concrete matrix comprises the tough and tensile layer of concrete, concrete efflorescence layer and floating ash and corrosion efflorescence layer.After the present invention will float ash and the cleaning of corrosion efflorescence layer, again reducing agent, reinforcing agent, renovation agent, flexibilizer and glaze agent are planted infiltrate described concrete matrix to deeply feel layer be described concrete efflorescence layer, through chemistry, physical treatment, inorganic material and the mixed first one of the tight affinity of organic material of planting infiltration with original basic unit are transformed into superpower anticorrosion, a waterproof based element mixing body to original liner.
