Abstract
The invention relates to a light coating for repairing a high temperature furnace and in particular relates to an alumina hollow ball high-viscosity light refractory coating. The alumina hollow ball high-viscosity light refractory coating is prepared from the following raw materials: 40-50 percent of alumina hollow ball, 5-15 percent of white corundum powder, 10-20 percent of alumina micro powder, 10-20 percent of pure calcium aluminate cement, 5-15 percent of aluminum dihydrogen phosphate solution with the concentration of 20-40 percent. The alumina hollow ball high-viscosity light refractory coating has the characteristic of high viscosity, is high in adhesion, can be rapidly combined with the original furnace lining when being coated at a crack or a pit, is short in maintenance time and can be rapidly roasted and used. After being subjected to high-temperature heat treatment, the coating can be sintered with an old lining together, the coating is high in strength, high in thermal shock resistance, difficult to crack and good in repair effect, the heat insulation effect of the alumina hollow ball lining in the high temperature furnace can be effectively improved, and the service life of the alumina hollow ball lining is prolonged.
Description
Technical field
The present invention relates to a kind of high temperature kiln and repair the lightweight coating of use, specifically a kind of alumina hollow ball matter high viscosity light-weight refractory coating.
Background technology
The conventional alumina bubble brick of the high temperature kiln furnace lining lining of working, reach the not only effect of high temperature resistant but also heat insulating, but it is expensive, disposable and maintain and replace input is very large.Alumina bubble brick belongs to lightweight refractory, its thermal shock resistance and intensity is all not as compact refractory material, and therefore in use, alumina hollow ball refractory lining is often because thermal shock or external shock ftracture, fall piece, cause kiln heat insulation effect to decline, affect kiln sintering effect.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of easy to use, respond well alumina hollow ball matter high viscosity light-weight refractory coating, this material outstanding feature is exactly high viscosity, adhesivity is good, spread upon crack or pit, can combine with original furnace lining rapidly, and curing time is short, can drops into fast baking and use.After high-temperature heat treatment, this coating can be sintered together with old lining, and intensity is high, not easy to crack.
The present invention solves the problems of the technologies described above adopted technical scheme to be: a kind of alumina hollow ball matter high viscosity light-weight refractory coating, adopt following raw material to make, the alumina hollow ball of 40%-50%, the white fused alumina fine powder of 5%-15%, the alumina powder of 10%-20%, the pure calcium aluminate cement of 10%-20%, the phosphate dihydrogen aluminum solution that the concentration of 5%-15% is 20%-40%.
In above-mentioned batching, the alum liquor that the phosphate dihydrogen aluminum solution that the concentration of described 5%-15% is 20%-40% is 20%-40% by the concentration of 5%-15% is replaced, the phosphoric acid that the concentration that also can replace with 5%-15% is 70 ~ 85%.
The granularity of described alumina hollow ball is 5-0.2mm, and the granularity of white fused alumina fine powder is 100-200 order, and the granularity of described alumina powder is 0.5 ~ 5 μ m.
Beneficial effect: a kind of alumina hollow ball matter of the present invention high viscosity light-weight refractory coating, there is high viscosity, while being spread upon alumina bubble brick crack or pit, can obtain good adhesivity, can combine with original furnace lining rapidly, and without maintenance, can direct baking intensification use.After high-temperature heat treatment, this coating not only can be sintered together with old lining, and intensity is high, good thermal shock, and not easy to crack, repair efficiency is good, can effectively improve heat insulation effect and the work-ing life of alumina hollow ball lining in high temperature kiln.
Embodiment
The following describes the specific embodiment of the present invention: a kind of alumina hollow ball matter high viscosity light-weight refractory coating, adopt following raw material to make, the alumina hollow ball of 40%-50%, the white fused alumina fine powder of 5%-15%, the alumina powder of 10%-20%, the pure calcium aluminate cement of 10%-20%, the phosphate dihydrogen aluminum solution that the concentration of 5%-15% is 20%-40%.
In above-mentioned batching, the proportion of phosphate dihydrogen aluminum solution is 1.4 ~ 1.5, the concentration of described 5%-15% is that the alum liquor that the phosphate dihydrogen aluminum solution of 20%-40% is 20%-40% by the concentration of 5%-15% is replaced, the phosphoric acid that the concentration that also can replace with 5%-15% is 70 ~ 85%.
According to above-mentioned formula batching, in cement plaster blender, be dry mixed evenly, add appropriate phosphate dihydrogen aluminum solution, after wet mixing evenly discharging and with mud smear, the instrument such as cleaver smeared to former furnace lining crack or pit, then artificial compacting, floating, through natural curing, after 6 ~ 8 hours, high temperature kiln can come into operation by normal temperature increasing schedule again.
