Abstract
The utility model relates to a fireproof heat insulation hollow ball which is hollow and forms a ball shape. The surface has protrusions. The hollow ball has the advantages of good heat insulation effect, rough surface, good bulk property, brings very large convenience to construction and application and can be widely used in various heat engineering equipment which need heat insulation and heat preservation.
Description
The utility model relates to a kind of refractory heat-isolating hollow ball, belongs to the fire-resistant heat insulating material field.
Refractory heat-isolating hollow ball is used widely in the heat insulation field of fire resistant heat preserving as alumina hollow ball, and hollow spheres has utilized the big characteristics of enclosed cavity thermal resistance, and good heat-insulation effect receives praises from customers.But existing hollow spheres outer surface is smooth, smooth entirely, and the accumulation space between ball and the ball is bigger, thereby thermal resistance is less, and hot conveying flow is short, and effect of heat insulation is still not good enough, and the ball that outer surface is smooth, smooth, its bulk property is poor, also makes troubles for construction, application.
The purpose of this utility model is to provide a kind of novel refractory heat-isolating hollow ball, this hollow spheres good heat-insulation effect, and bulk property is good, easy construction.
The purpose of this utility model can be realized by following scheme:
Described refractory heat-isolating hollow ball, hollow, be spherical, there is projection on its surface.
For the convenience of moulding with make the surface more coarse, can make the whole surface of ball all be covered with projection.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1, structural representation of the present utility model also are an embodiment.
The sectional view of Fig. 2, Fig. 1.
Among the figure: 1 hollow spheres, 2 rats, 3 enclosed cavities.
As shown in the figure, it is hollow that hollow spheres 1 has enclosed cavity 3 to form, and its surface is furnished with projection 2.
During preparation, available foamed polystyrene ball is as ball, put into nodulizer, start nodulizer and rotate with 80 rev/mins speed, spray adds 5% poly-vinyl alcohol solution Bond about 8 seconds, loose and added the aluminium-silica fireproof powder of 220 mesh sieves, after about 2 minutes, spray adding additives simultaneously and add refractory powder, the rotating speed of adjusting molding machine is 40 rev/mins, regulate the sprinkling situation of Bond and the interpolation situation of refractory powder, make the semi-finished product ball up to making the ball surface form projection 2.With the oven dry kiln drying of semi-finished product ball dress saggar about 300 ℃, to moisture content less than 1%, go into klining, firing temperature is 1350～1400 ℃, during high temperature, decompose to vapor away as the foamed polystyrene ball of ball and stay enclosed cavity 3 and form hollowly, make the utility model refractory heat-isolating hollow ball after the cooling.
The volume density of this hollow spheres is 0.5g/cm
3, packing density is 0.3～0.5g/cm
3, thermal conductivity is: 400 ℃ during to 0.15,1000 ℃ 0.157, and volume compressive strength 1.5～6MPa/cm
3, refractoriness is 1600～1900 ℃.
There is projection on this refractory heat-isolating hollow ball surface, and projection is interlaced, and the accumulation space between ball and the ball is reduced, increase thermal resistance, and the conveying flow of heat is prolonged, further improved effect of heat insulation, this hollow spheres rough surface, bulk property is good, also brings convenience for construction, application.Can be widely used in the various Thermal Equipments that need heat-insulation and heat-preservation, also can be used for other industry, as can be used as catalyst carrier and use.
Claims (2)
1, a kind of novel refractory heat-isolating hollow ball is hollow, is spherical, it is characterized in that there is projection on the ball surface.
2, hollow spheres according to claim 1 is characterized in that the whole surface of ball is covered with projection.
