The invention discloses a kind of lining brick (building block) and production method thereof of non-baked light-weight heat-insulating acid-resisting.Building block is used for chimney stalk, flue lining, lightweight, heat insulation, acidproof.It is mixed by tackiness agent water glass, coarse aggregate haydite, fine aggregate pottery sand, coarse fodder casting powder, solidifying agent Sodium Silicofluoride and forms plastic pug through stirring, and pour mould inner pressure into and make the disjunctor building block, the demoulding after drying, dry again, cut into single building block at last.Building block two sides or four sides are provided with the tenon or the tongue-and-groove of multiple shape, and tenon and tongue-and-groove can be meshing with each other between the building block.This building block moulding is simple, can prevent that flue gas from appearing, and is convenient to construction, light heat-insulating acid-resisting.
Description
The present invention relates to a kind of lining brick and manufacture method thereof of non-baked light-weight heat-insulating acid-resisting.
Chinese large-sized fuel-burning power plant and main structure-chimney are the construction method of the former Soviet Union of continuity, and chimney shaft is made of reinforced concrete, and the inner lining brick adds thermofin between stack shell and air retaining wall.Because what the continuous expansion of generating set and environmental protection standard required improves constantly, also thereupon constantly to high, great development, the 80m from the past progressively develops into present 210m, 240m and 270m to chimney.And the trend of further increasing is arranged, increasing.On the other hand, because cleaning apparatus also progressively from the water dedusting, changes electric precipitation into, so flue-gas temperature has also had raising.
Therefore no matter be from the primary structure design, still on inner lining material and building structure, can't satisfy the working condition of chimney operation, so passed through from a large amount of investigation of the eighties since the middle and later periods, find chimney ubiquity cracking and etching problem, the chimney time that has is not long, just is forced to abolish.So not only cause the tremendous economic loss, and directly injured the safe operation of power plant.Thereby caused all circles' great attention, chimney is treating to rise to as equipment as structures and treat from the past also.
It is many-sided causing chimney cracking and reason for corrosion, but one of them very important reasons be exactly material capability and build by laying bricks or stones (liner) structure, that is to say, inner lining material (building block) should possess good anti-sulfuric acid (sulphur in the flue gas can be produced acid gas) corrosive property and good insulative properties, destroy the cracking cause and destroy the corrosion that causes because of acid gas because of thermal stress preventing, guarantee that from building structure perps is full simultaneously, closure is good, prevents that flue gas is to thermofin and wall of the outer-rotor infiltration.
Yet existing inner lining material clay brick, refractory brick, clay common brick, acid-proof ceramic tile, grouan building block etc., all in various degree have respectively that heat-proof quality is poor, unit weight big, increase foundation load, masonry construction stopping property and globality is poor, flue gas easily permeates, cohesive strength is low, be unfavorable for antidetonation and the shortcoming that acid resistance is weak, the speed of building by laying bricks or stones is low.
The refractory brick of similarly making through the stove roast is arranged in the prior art, as CN1061208 red silica serial fire-brick and production method thereof, providing a kind of is base-material with common brick stone, add the pug that water glass, aluminum phosphate, Sodium Silicofluoride, glass powder, talcum powder etc. are formed with thick, fine particle, go into mold forming after the refractory brick that stove roast system forms.Its shortcoming is that matter weighs, need fire.Then there is aforesaid defective in this brick as not firing, and can not use.
The objective of the invention is to overcome the defective of heavy, heat insulation poor, the acid resistance difference of matter that present building block exists, a kind of non-agglomerating light weight of being made up of tackiness agent, coarse-fine aggregate, powder, solidifying agent, heat insulation, acid proof building block and production method thereof are provided.
In order to achieve the above object, the present invention adopts following solution.
Chimney light heat-insulation acid-proof building block main ingredient has tackiness agent, coarse-fine aggregate and powder, solidifying agent.Require this building block except that satisfying general building block technique performance, also will possess multi-functional high temperature resistant, heat insulation and the acid resistance dielectric corrosion simultaneously.Therefore, select the engineering philosophy of raw material to be:
(1) tackiness agent and raw material itself should have the performance of high temperature resistant, lightweight heat-proof and acid resistance dielectric corrosion.
