Abstract
A kind of high temperature clay is to be that matrix is equipped with white alundum powder and/or aquamaine stone flour by high alumina, and it is formulated to form composite adhesive with alum liquor and phosphoric acid and aluminium hydroxide.This high temperature clay has the cohesive strength height, has good workability, and anti-thermal shock, wear-resisting wiping, protection against corrosion, characteristics such as adaptability is strong are applicable to the various Industrial Stoves of industries such as metallurgy, building materials, lightization.
Description
The present invention relates to fire resisting material field, particularly be applicable to the high temperature clay of building by laying bricks or stones, repair, smearing and spray of Industrial Stoves refractory brick.
Build the clay or the high-alumina chamotte of industrial kiln at present by laying bricks or stones, it is formulated with water to add raw clay about 30% with clay or high-alumina powder clinker, this class refractory mortar is owing to exist raw clay and water, under the furnace temperature effect, produce to shrink and water is evaporated and stays a large amount of pores, cause brickwork joint to loosen, be difficult to bear the washing away of kiln high temperature gas flow, the bump of material, friction, cause masonry to begin to damage the life-span of having reduced kiln from brickwork joint.Research is both at home and abroad made binding agent with phosphoric acid, domestic No. 701 mud of succeeding in developing are refractory mortars (7～12 pages of the 2nd phases of " refractory materials " nineteen eighty-two) of making binding agent with the phosphoric acid of concentration 85%, though have cohesive strength and high-temperature behavior preferably, have shortcomings such as cost height, trickling, precipitation and workability difference.
The objective of the invention is to overcome the shortcoming of prior art, develop a kind of low temperature intensity height, high-temperature behavior is good, and production technique is simple, and cost is low, is convenient to construct and the novel refractory clay of standing storage.
The contriver has studied successfully a kind of prescription and compound method thereof of the refractory clay that can achieve the above object finally through studying repeatedly and putting into practice.Now that dispensing information of the present invention is as follows, prescription of the present invention divides main material and binding agent two partly, and wherein main material formula is:
(1) high-alumina powder clinker (AL
2O
3Content is no less than 75%) 85～100 weight %;
(2) white alundum powder (AL
2O
3Content is no less than 94%) 10～0 weight %,
(3) aquamarine stone flour (AL
2O
3Content is no less than 55%) 5～0 weight %.
The prescription of binding agent (outer dosage accounts for main material weight %):
(1) alum liquor 19～23%
(2) dihydro aluminum phosphate solution 10～15%
The following describes the effect of each component of the present invention: high-alumina powder clinker is a matrix, and adding a small amount of white alundum powder and being is to improve refractoriness and load softening point, for use in building by laying bricks or stones or the repairing of the high temperature position of other stove kind of High Temperature Furnaces Heating Apparatus kinds such as large blast furnace.But be used for stove kind below 1400 ℃ can be less with or without white alundum powder and aquamarine stone flour, so that reduce cost.Kyanite is as swelling agent (1500 ℃ expand 17%), and the hole that produces with water evaporates in the compensation clay generates mullite during high temperature in addition, and refractoriness can reach more than 1800 ℃.
The mechanism of action of binding agent is: alum liquor, the dihydro aluminum phosphate solution that the phosphoric acid adding aluminum hydroxide forms, two kinds of solution mix the back combination reaction take place, become compound binding agent, the powder particle bond mutually And can and refractory brick surface form reactant, the raising masonry strength, its cohesive force is higher than other binding agents such as phosphoric acid.
The compound method of high temperature clay of the present invention is as follows:
(1), single with mixing an amount of white alundum powder and/or aquamarine stone flour in high alumina or the high-alumina powder clinker according to stove kind refractoriness needs;
(2) industrial sulphuric acid aluminium powder thin up is to required proportion (d=1.0～1.35 gram per centimeters
3), make alum liquor;
(3) allotment dihydro aluminum phosphate solution: aluminium hydrate powder is added water furnishing pasty state, be blended into phosphoric acid and constantly stirring again, till evenly, phosphoric acid and aluminium hydroxide generation thermopositive reaction, filter usefulness more after cooling, proportion d=1.2 when being made into 20 ℃～1.3 gram per centimeters
3Solution.
High temperature clay of the present invention once used in Industrial Stoves such as fluidizing furnace, tunnel furnace, rotary heating furnace, water chestnut kiln, glass kiln, kiln car, received very good effect, used the result to show that the high temperature clay has following characteristics:
(1) not just influenced by brickwork joint size and furnace temperature, not loose, do not run off, have good workability.
(2) cohesive strength height leaves behind from the 3rd buildings after 150 ℃ of oven dry and does not ftracture, and ultimate compression strength is similar to high alumina brick in the time of 1300 ℃.
(3) heat resistanceheat resistant
, wear-resisting wiping, protection against corrosion, adaptability is strong.
(4) incorporation degree is good, and dehydration is moderate, and is easy to use.
Embodiment:
Press the column weight amount and be mixed with 100 kilograms of clay:
(1) high-alumina fly is 62.9 kilograms
(2) white alundum powder is 7.4 kilograms
(3) the aquamarine stone flour is 3.7 kilograms
(4) alum liquor is 15.6 kilograms
(5) dihydro aluminum phosphate solution is 10.4 kilograms
The clay that modulates by prescription of the present invention and compound method is made test block ， And with general high alumina matter chamotte and phosphoric acid mud material as a comparison, makes test block equally, carries out various physical property tests, and it the results are shown in table 1.
As seen from Table 1, clay of the present invention increases substantially than the performance of high alumina matter chamotte, compares with the phosphoric acid chamotte of superior performance, and load softening point improves 210 ℃, burn back ultimate compression strength and slip resistance and all improved, particularly hot strength improves more remarkable more than 1000 ℃.
Using proves that high temperature clay of the present invention is applicable to the various kilns of industries such as metallurgy, building materials, lightization, building by laying bricks or stones and repairing as blast furnace, coke oven, ladle, process furnace, tunnel furnace etc.Prolong the masonry life-span, receive good economic benefit.
During preparation, good alum liquor of weighing and dihydro aluminum phosphate solution are modulated into composite adhesive in proportion, are blended in the dried mixed main material powder, and mix is to the nothing caking with till rolling into a ball.Mixing process discharges a large amount of hydrogen, and the clay bubbling makes volumetric expansion, therefore must allow it fully react, and last clay is slightly acidic pH=1.5～2.
The contrast of table 1 physicals
