High temperature is fireproof mud
Clay is fireproof mud, clay is fireproof mud.
Saggar is industrial name, main and mineral the hydrate that is clay mineral and aluminium. Sticky earthy and fireproof mud.
Saggar fireclay abbreviation is soft qualitative clay. It is a kind of saggar that has plasticity. Compositive mine owner if kaolinite, much water kaolinite, Shui Yun's mother waits. Contain Al2O3≥22% ～ commonly 30% , si02≥42% 73% , fireproof 1670 ℃ of degree of 1580 ～ . Bubble of this kind of saggar is in water molten, with water hind can make it all sorts of appearance, it is the raw material that makes fireproof material, mix as binder in horniness saggar. The chemical composition according to soft qualitative saggar (useful constituent, harmful constituent) , physical function (fireproof degree, plasticity, burn break a quantity to wait) can differentiate for labour, Ⅱ , Ⅲ 3 grade.
Fireproof mud deploys a method:
Stick earthy and fireproof mud make up clay content of the Al2O3 in fireproof mud > 40% , work with high grade cement or tall aluminous cement and argillaceous fireclay mix even, quality comparing is (cement: ? Wu?1:2Or 1:3, add water agitate, tone is become without piece stiff mushy can. Use fireproof sludge only not mix into cement is harmonic, agglutinant with intensity bad, because of its after classics high temperature, lose felt action and become farinaceous, from the brick the teem in seaming, cause bricky body to become loose, ballot drops bricky time frequent, part of the day of can serious shadow is produced. A month dropped some factory 4 times brick, movement cannot constant. Handle this kind of circumstance to only support adds iron plate, perhaps destroy serious step.
Fireproof mud uses a method:
1, sweep the chamber of a stove or furnace clean above all, also call mud of aluminous acerbity brine to hang an oar 9 times to the chamber of a stove or furnace first with fireproof cement, wait for the reoccupy after working fireproof cement and fireproof sand, press 1 than 1 mix up, one part fills partly inside the chamber of a stove or furnace, use fact of light clap of small rubber hammer next, wait for whole the chamber of a stove or furnace to knock solid after filling, fireproof cement hangs reoccupy 9 times oar, dry in the shade is controlled one week, with fettling of this kind of method, the chamber of a stove or furnace does not have crack!
2, by fireproof pink makings, bond and additive are comprised. Almost all fireproof raw material can be made expect with the pink that will make up fireproof mud place to use. Add with fireproof grog pink right amount model clay makes bond and plasticizer and can make weigh common and fireproof mud, intensity of its normal temperature is inferior, pottery and porcelain is formed to combine ability to have below high temperature relatively high strenth. Serve as bond with water rigid, gas rigid or material of hot rigid union call chemical union fireproof mud, in under the chemical response with before forming pottery and porcelain to combine temperature, arise proper namely sclerosis.
3, the granuality basis of fireproof mud uses a requirement and different, its maximum size is less than 1mm commonly, some is less than 0.5mm or finer.
4, the capable person that chooses fireproof slop is qualitative, the material of the refractory products of Lv of take an examination and body of build by laying bricks or stones agrees character. Fireproof mud divides build by laying bricks or stones to seam material outside, also can use daub law or eject law to use as the protective coating of line system.
Fireproof mud character reachs application:
1, plasticity is good, construction is convenient;
2, bonding strength is great, the capability that fight corrode is strong;
3, fireproof degree taller, can amount to ℃ of 1650 ℃ ±50;
4, it is good to fight broken bits to invade a gender;
5, heat flakes the gender is good. Fireproof mud basically applies at furnace of kiln of industry of hot-blast stove of furnace of kiln of Jiao Lu, glass, blast furnace, other.
6, applied industry:
Metallurgy, building materials, mechanical, petrifaction, glass, boiler, electric power, steely, cement.
Fireproof material sort is various, press normally
Fireproof degree
Cent of on any account is common and fireproof material (1770 ℃ of 1580 ～ ) ,
Advanced and fireproof material
(2000 ℃ of 1770 ～ ) with fancy and fireproof material (2000 ℃ above) ; By chemical character cent is
Acidity and fireproof material
,
Neuter and fireproof material
And
Alkalescent and fireproof material
. In addition, useful still the fireproof material at special situation.
Is what fireproof mud pledges according to comprising capable person different and OK is cent: ? Oath of forest of a gathering of things or people dash forward Wu yo ⒏ Lin Shi dash forward oath of shaddock of Wu yo ⒐ dash forward oath of bureau of Wu yo ⒚ dash forward Wu lament takes? fireproof mashed vegetable or fruit according to bond different,
(1) pottery and porcelain combines fireproof mashed vegetable or fruit it is by fireproof fine aggregate and bond of pottery and porcelain (plasticity clay) compositive compound. Delivery position is dry state, after needing to add water, use, sclerotic below high temperature through union of pottery and porcelain.
(2) water rigid combines fireproof mashed vegetable or fruit it is by fireproof fine aggregate and the water rigid bond that have main union effect (cement) compositive compound. Delivery state is only dry state, after adding water, use, need not heat when sclerosis.
(3) chemistry combines fireproof mud to be mixed by fireproof fine aggregate chemical bond (inorganic, organic one inorganic, organic) compositive compound. Delivery position can be oar shape already, can be dry state, in combine temperature under pottery and porcelain sclerotic. According to curing temperature, this kind of fireproof mud can divide the rigid that it is gas and hot rigid two kinds. Gas rigid is fireproof the gas rigid bond such as commonly used water glass makes up mud. Hot rigid is fireproof the hot rigid bond such as commonly used phosphoric acid or phosphate makes up mud. This kind of hot rigid is fireproof after mud is sclerotic, except have higher strength below all sorts of temperature beyond, still have systole rigor of small, juncture, be able to bear or endure corrode sex is strong wait for a characteristic.
Finished product of fireproof sludge component and semi-manufactured goods two kinds. Alleged finished productFireproof mudProducing manufacturer to already had matched raw material, grog in proportion namely, when the spot is used, need to add water agitate by the standard only even can; semi-manufactured goods or blame finished product are fireproof mud is raw material and grog not since mix into syncretic, when the spot is used, the composition that presses different slop mixes adequately, add water agitate by the regulation even can.
