Abstract
A multi-purpose refractory water-proof material is composed of high-magnesia powder (MgO is greater than 50%) or high-alumina powder (Al2O3 is greater than 60%) (40-70 Wt.%), high-alumina cement over No.625 (8-18 Wt.%), refractory clay (10-25 Wt.%), electrically dusted coal ash (4-13 Wt.%), calcium carbonate (2-5 Wt.%) and sodium fluosilicate (1-5 Wt.%), and features easily available raw materials, low cost and high strength. It can be used to make bulk refractory with light weight, low thermal conductivity and low expansibility.
Description
The present invention relates to fire-resistant and building material technical field, specifically high temperature resistant the and water-proof material of multi-usage.
Powder in the present domestic unshape refractory is mostly used the high magnesium powder of content (MgO 〉=91%), aluminium powder (Al2O3 〉=85%), chromium powder (Cr2O3 〉=40%)).These powder price height, the material source difficulty.The caking agent that is adopted has high-alumina cement, aluminum phosphate, and Tai-Ace S 150, polymerization of sodium phosphate, there is the construction process requirement height in resol etc., and setting time is long.As use the ortho-water glass binder, its use temperature≤1200 ℃ can not adapt to the place of comparatively high temps.Above-mentioned powder only is used to make atypic refractory materials.
The objective of the invention is to overcome deficiency of the prior art, provide a kind of raw material to be easy to get, low price, easy construction, curing time is short, and the multi-usage that intensity is high is high temperature resistant and water-proof material.
The present invention is achieved in that the high temperature resistant and water-proof material of multi-usage of the present invention is by (weight ratio) high magnesium powder (MgO 〉=50%) or high-alumina fly (Al2O3 〉=60%) 40-70%, high-alumina cement 8-18% more than No. 625, clay refractory mortar 10-25%, electric precipitation coal ash 4-13%, lime carbonate 2-5% forms, and other adds Sodium Silicofluoride (accounting for gross weight) 1-5%.Above raw material mixed blend together powder, granularity 〉=120 orders.
Above-mentioned powder mixed can be made into unshape refractory with refractory aggregate, its blending ratio is that powder accounts for 1/3, and refractory aggregate accounts for 2/3.Refractory aggregate determines its granular size according to cast thickness, and available old refractory brick is smashed and is made into.
Above-mentioned powder also can be used for waterproof or mending-leakage in concrete roof and the structure, directly with above-mentioned mixed powder filling or place, brushing slit.
No matter be to make unshape refractory or make concrete roof or the structurally waterproof mending-leakage, all use neutral water glass as caking agent, consumption only accounts for the whole 10-25% that expects weight admittedly, and water is adjusted rare thick mix thoroughly back cast or brushing then.Neutral water glass and coal ash, calcium carbonate chemistry react completely, the requirement that can reach dried soon, bubble is few, intensity is high, coefficient of linear expansion is little.
The invention will be further described below in conjunction with embodiment.
Embodiment 1, with high magnesium powder (MgO 〉=50%) 5% (weight ratio), high-alumina cement 16% more than No. 625, clay refractory mortar 14%, and electric precipitation coal ash 13%, lime carbonate 5%, other adds Sodium Silicofluoride (accounting for solid material gross weight) 4%, mixes to mix and makes powder.
Powder mixed can be made into unshape refractory with refractory aggregate, its blending ratio is: powder accounts for 1/3, and refractory aggregate accounts for 2/3.Can use it for various boilers, process furnace cast refractory concrete.
Embodiment 2, and with high-alumina fly (Al2O3 〉=60%) high-alumina cement 14% more than 60%, No. 625, clay refractory mortar 9%, electric precipitation coal ash 13%, lime carbonate 4%, other adds Sodium Silicofluoride (accounting for solid material gross weight) 3% and mixes and blend together powder.Make caking agent with neutral water glass, its consumption accounts for 15% of solid material.Above-mentioned materials is used for joint filling mending-leakage on the precoated plate roofing, or is used to clog the mending-leakage of precoated plate breach.
Material of the present invention can be used for metallurgical furnace kiln, the Industrial Boiler of temperature up to 1600 ℃ and (comprises the power station Boiler) and the serious special stove of acid and alkali corrosion is arranged, such as liner or the lining coating of paper industry alkali recovery furnace etc. Its easy construction, cheap, can the extension device life-span.
When being used on precast concrete roof boarding and the xoncrete structure mending-leakage, compare with existing other material, Have characteristics durable, that construction is simple, free from environmental pollution, effective.
During as the liner of domestic coal range, can prolong more than two times service life.
Material of the present invention has raw material and is easy to get, low price, easy construction, the advantage that intensity is high. Make not The existing refractory material of its weight ratio of amorphous refractory is light, and thermal conductivity factor and the coefficient of expansion are all lower.
