Fireproof puddleAbbreviation is fireproof mud or fireclay, it is build by laying bricks or stones fill firebrick is used when furnace seam the whole with make mutual cohere makes body of build by laying bricks or stones is had certain gender, intensity is amiable the material of close sex. Because this is fireproof,the hot loss of mud that uses quality of pair of style of build by laying bricks or stones, hot plate and furnace casing temperature are having distinct effect.
YesFireproof mudthe requirement is as follows:
(1) can move the wrong part of brick of certain consistency, fill with water, do not produce crackle;
(2) and close of bricky style quality (be like fireproof degree, loading bate temperature) ;
(Fall with high temperature after 3) is dry use the air-tightness; with have better
(4) has particular mechanical strength and very good air-tightness.
Commonly used fireproof mud has sticky earthy, tall aluminium qualitative, silicon is qualitative, magnesian qualitative fireproof mud. When build by laying bricks or stones builds clay firebrick, use sticky earthy and fireproof sludge. Sticky earthy and fireproof mud is by sticky earthy grog and union clay is comprised, its composition sees a table 1.
Express component of 1 sticky earthy and fireproof sludge (% )
When build by laying bricks or stones builds tall aluminous brick, use tall aluminous qualitative fireproof sludge. When build by laying bricks or stones builds the tall aluminous brick that contains Al2O360%-70% , when adoption fireproof sludge comprises; build by laying bricks or stones to build the tall aluminous brick that contains Al2O348%~55% by the burns alumina and 10%-20% unripe clay of 75%~85% , also can use tall fireproof spent sticky earthy and fireproof mud.
When build by laying bricks or stones builds silica brick, applied SiO2 content is able to bear or endure character for the silicon of 90%~93% fireclay, its grain comprises: Remain is more than in the grain on 1.0mm screen mesh 3% , the grain that goes up through 0.20mm screen mesh is less than 80% .
When build by laying bricks or stones builds magnesia brick, use magnesian qualitative fireproof sludge, its are magnesian content is less than 78% , oxidation silicon content is less than 6% , calcination alkali number is more than 2% . Composition of granuality of magnesian qualitative fireproof mud is: Be less than 1mm occupy 100%; to be less than 0.5mm not less than 97% , be less than 0.125mm not less than 50% .
Tall aluminous brick
, argillaceous brick matchs fireclay proportion is 3-5% commonly.
Alkalescent brick
Matching fireclay proportion is 1.5-2%
Brick of light qualitative clay
Match fireclay proportion for 10%
Silicon qualitative brick
Match fireclay proportion for 5%
Phosphatic brick
Match fireclay scale to be 3-5%
Carborundum brick
Match fireclay scale to be 3-5%
Usually, slop is used when firebrick build by laying bricks or stones is built must the chemistry with firebrick is identical.
The item characteristics of fireproof puddle
Combinative strength is high, it is good that build by laying bricks or stones builds integral structure
Air-tightness is good, fight erode, service life is long
Loading bate temperature is high, high temperature systole is small
Mix easily the gender is good, bonding strength is high, the systole after burning is small
The sex that fight broken bits is good, build by laying bricks or stones builds ash to seam small
The density of fireproof puddle
Build by laying bricks or stones of fireproof puddle foundation builds high temperature bricky material asks character, choose with material qualitative pink makings adds inorganic bond, the new-style and inorganic cementing material that after additive classics reacts, makes. Fireproof puddle has Aesop high temperature RM 1400, RM1600, RM1750 3 grade, can build product data according to build by laying bricks or stones, the high temperature that chooses relevant material to pledge is fireproof daub.
Fireproof puddle recipe
Fireproof puddle, its feature depends on including 20-40% of Bai Yugang of 1.5-2mm of raw material of undermentioned weight per cent, bai Ni 20-40% , carbon black 5-8% , 2-5% of small silicon pink, urea 10-20% , 3 get together 5-10% of phosphoric acid natrium, french chalk 2-5% .
Our company optimized a recipe each constituent deserves to compare, high temperature resistant, anti-corrosive, intensity is high, jam not easily, not easy ageing, use life is long, fight flake performance is good, aseismatic stability is good wait for an advantage.
High temperature is fireproof slop, often also be called high temperature fireclay, basically be the juncture material that builds system of refractory products build by laying bricks or stones as build by laying bricks or stones, the fireclay great majority that sells on the market is powder shape, water is joined to make slop use in construction site.
(1) raw material: High temperature fireclay is to use kaolin of tall aluminium powder, this locality, adscititious plasticizer, the agent that decrease water and aid burn an agent to make up and become.
(2) bond: By its the property of bond can be divided for pottery and porcelain rigid of union, water is united in wedlock, chemical union and organic union 4 kinds.
(Condition of fireclay of 3) high temperature: High temperature fireclay has two kinds of state: One kind is powder shape, one kind is slop shape. Most fireclay is powder shape, add water modulation to become slop state only in construction site can, add water to measure commonly in 25%~30% .
(4) high temperature is fireproof slimy function: The function of fireproof mud wants requirement high temperature to match with the function photograph of brick of corundum of body of build by laying bricks or stones, can experience all sorts of chemistry inside furnace and physical effect likewise with corundum brick below high temperature. Ask to furnace of high temperature kiln in petro-chemical enterprise integral structure sex is good especially, air-tightness is tall, seam a requirement to brick of body of build by laying bricks or stones small (most requirement is less than 1mm) . Ask the granuality of fireproof mud is fine so, cohere sex is good, cohere time shoulds not be too fast.
