What is zirconia hollow ball brick?

Hollow ball brick wants zirconia the product of fire prevention of adiabatic heat preservation that with zirconia hollow ball makes for crucial raw material. Its produce technological process is, it is raw material with zirconia, hydrogenous oxidation is calcic (or magnesian etc) make thickener, via well-balanced mix up, electric Gu law fuses frit fluid, compress gas happening with air furnace makes zirconia hollow ball, subsequently with zirconia hollow ball (65%70%) and zirconia are fine pink (30%35%) is raw material, make shirt-sleeve lotion with boric acid solution, mix up is well-balanced be over with fill pressure shake forming machine figuration, after making extraction base substrate do impetuous become in the fire in 1700-1800 ℃ high temperature.


Zirconia arenaceous brick wants with zirconia arenaceous for raw material, add shirt-sleeve agent more, mix up is well-balanced be over with fill press oscillatory figuration, after making extraction base substrate classics do impetuous again the fire below 1780-1800 tall . Goods of zirconia arenaceous brick is complete by zirconia arenaceous make, have admirable tall compressive strength and smooth go outing are stomatic and tectonic, it is the goods of fire prevention of adiabatic heat preservation with high quality character, safe operation temperature achieves 2300 ° C. The high temperature kiln of the manufacturing industry such as smelt of stuff of metal of for military use of crucial and general in order to, scientific research, high melting-point, crystallization, calcite, electronic parts furnace. If beryl produces the long brilliant heat of the industry, tungsten makes the room such as the furnace of intermediate frequency induction of the industry.
Hollow ball and goods have zirconia fire prevention temperature is high, cubage is opposite density is small, hot be in harmony is small, conduct heat coefficient is low, sex of adiabatic heat preservation is strong, furnace of reasonable promotion cellar is efficient, reduce production to make periodic time. Long-term sex applies temperature to be able to accomplish 2200 ℃ , conduct heat rate 50% what be AL2O3 about, apply below hydrogenous atmosphere very smooth, connecting the application on furnace of induction of radon intermediate frequency to be able to promote service life 30-40% .
That is to say of oneself of air oxidation knot that production of zirconia production ground makes raw material of fire prevention of a kind of tall Ji , temperature of be in harmony is very strong, but the temperature category that outspread viscosity transforms, have first-rate hear resistance, can promote glair fight craze character to because its organic chemistry plasticity is big,be returned, the organic chemistry reliability that reason can promote glair and anti-corrosive working ability, return the effect that can have lacteal chaotic agent, accordingly, the deck is built in the project, zirconia had quite big effect.
The product of fire prevention of adiabatic heat preservation that with zirconia hollow ball makes for crucial raw material. (Of this kind of brick advocate brilliant photograph is cubic zirconia (the 70%~80%) that occupies mineral photograph to form about, fireproof degree exceed 2400*C, show hole to lead 55%~60% , cubage is opposite density 2.5~3.0g/cm3, compression experiment compressive strength not under 4.
9MPa, 0.23~0.35w/(mK) of coefficient of thermal conductivity. The production of hollow ball brick makes zirconia the production of hollow ball produces means and ferric oxide means fundamental - appearance, mere its are fused temperature is higher, want to accomplish 2700*C left and right sides to show level China to choose CaO generally to be thickener.
Additional, the wear-resisting function of zirconia raw material, extend a gender, compressive strength, intensity is very high, and Pbt material is corroded very tall also, there often is general application in the various industry such as optics of fireproof insulation material, mechanical automation, electron, china.
The characteristic: of zirconia? Murder of wholesale   changes a leg to take corrode of dip of  Bt material, fight coefficient of caustic of oxidation, wear-resisting, linear expansion big, smooth zirconia already became fireproof insulation material to make the crucial raw material that industry and industry of special type ceramics cannot ignore.
The bubble pottery and porcelain that 1) smooth zirconia makes can use the worry unnecessarily with gold of tall stage, bubble pottery and porcelain applied the worry unnecessarily at molten steel steel rolling to achieve admirable clean and actual result.
2) because intensity of stability 2 zirconia is high, can make rod of knife of material of mill of cutting tool of the model of hairdressing of Leng Cheng special tool, plastics, model that pull silk, cutting, fish, shears, golf first-class.
Compressive strength of 3) stability 2 zirconia it is tall, good to extend a gender, consequently, can produce prefabricated components of production derv engine with a future life, wait like cap of lever of the line in crock of push rod, crankshaft, needle bearing, piston.
4) smooth zirconia, have semiconductor material sex and more sensitive characteristic, can make diaphragm of solution of electrolyte of solid state of batteries of tall solid state wait.
