Abstract
The invention provides a refractory fibre anti-radiation and anti-scour coating prepared from an inorganic adhesive, enamel powder, reinforced short fiber and bubble zirconia packing through the following steps of: mixing all the materials, and stirring to form a thick and viscous paste object; knife coating on the surface of a refractory fibre heat insulation layer on site to form a coating layer with the thickness being more than 3mm, wherein the coating layer can be used after being dried. The refractory fibre anti-radiation and anti-scour coating is used for solving the problems devitrification and powder falling of the refractory fibre of a refractory heat insulation layer of a stove kiln and particularly a refractory fiber heat insulation layer on a counter-fire surface and improving the working environment of the refractory fibre; and the coating has an anti-radiation function, therefore, the surface temperature of the refractory fibre is greatly reduced, and the service life and the heat insulation effect of the refractory fibre heat insulation layer are guaranteed.
Description
Technical field
The present invention relates to a kind of refractory fibre coating, especially a kind of refractory fibre counter radiation antiscour coating.
Background technology
In the severe environment that Industrial Stoves high temperature, air flow are washed away; As the refractory fibre of stove refractory insulating layer under intensive oxidation/reduction exterior guiding; The refractory fibre thermal insulation layer of crystallization, shedding lentamente, especially counter-fire face, the shedding phenomenon is particularly outstanding; Cause the refractory fibre thermal insulation layer sharply to shorten work-ing life, the fire resistant heat preserving effect acutely descends.
Technological drawbacks such as the major technique means that solve refractory fibre thermal insulation layer crystallization, shedding at present are to lay refractory brick at the counter-fire face, and refractory brick heaviness and specific heat are big, cause difficulty of construction to strengthen, and burner hearth heats up slowly, energy consumption is big.
Summary of the invention
Problem to be solved by this invention provides the counter radiation antiscour coating of a kind of brushing in the refractory fibre insulation layer surface; Be used to solve the refractory fibre of stove refractory insulating layer; Especially the crystallization of the refractory fibre thermal insulation layer of counter-fire face, shedding phenomenon are improved the refractory fibre Working environment; And coating self has the counter radiation function, reduces the refractory fibre surface temperature greatly, protection refractory fibre thermal insulation layer work-ing life and heat insulation effect.
For realizing above-mentioned purpose, technical scheme of the present invention is: a kind of counter radiation antiscour coating that is used for the refractory fibre insulation layer surface, form by inorganic adhesive, one-tenth glaze powder, enhancing staple fibre, zirconium white hollow ball filler.
Described inorganic adhesive by weight percent be 70% silicon sol, 30% biphosphate aluminium powder in reaction kettle, under 120 degrees centigrade of envrionment temperatures, stir and made in 60 minutes, wherein the silicon sol modulus is 2.
Described one-tenth glaze powder is 95% china clay by weight percent, and 5% titanium oxide is mixed, and wherein the china clay whiteness is greater than 85.
Described enhancing staple fibre is a silicon carbide whisker.
Described zirconium white hollow ball filler is the zirconium white hollow ball of diameter 1-3 millimeter.
The method of use of refractory fibre counter radiation antiscour coating of the present invention is: become glaze powder, 5-30% to strengthen staple fibre, the mixing of 55-70% zirconium white hollow ball filler inorganic adhesive, the 15-60% of above-mentioned 15-35% weight hundred ratios; Stir into thickness paste object; On-the-spot blade coating is in the refractory fibre insulation layer surface; Form coating more than 3 millimeters, can use after to be dried.
Refractory fibre counter radiation antiscour resistant high-temperature oxidation resistance of the present invention is strong, and especially result of use is good in the environment of temperature below 1700 degrees centigrade, forms hard, bright high temperature resistant glaze layer behind the coating sintering; High temperature resistant flame flow washes away; The counter radiation effect is remarkable, 1300 degrees centigrade of furnace temperature, and refractory fibre insulation layer surface temperature is 350 degrees centigrade during paint coatings 8 mm thick; Construction is simple, and energy-saving effect is remarkable.
