Application :

High alumina refractory cement CA50,have passed the ISO international quality certifify.According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.They have the advantage of longer setting time,can resist high temprature,better stability in air,rapidly strength,no addivity and suitable for confect all kinds of castables and low cement refractory castables,refractory concrete,ramming mixes, gunning mixes and manmade marble bricks etc.

Q:The performance of refractory material
As for easticity modulus, you can serach for information on the Internet or specialized books.
Q:For refractory, what is critical particle size? Thank you.
000000
Q:Physical and chemical indicators of various refractory.
There are too many of them.
Q:How to use fireclay?
Actually, fire clay is not strong. Fireclay are all clinkers with no strength, also known as "blade mud". It is used as the filler with a thickness of not more than 3mm. Therefore, it can not be used for thermal insulation inside the furnace. Inner thermal insulation of the civil boiler can use "alumina cement", also known as refractory cement.
Q:who knows the technology of fireproofing material?
First: Firstly, you should produce the recipe and prepare the raw materials, for example, if you prepare to produce 1 ton, you should compute the recipe sheet of 1 ton producing; check whether the raw materials are complete; second: make the color and filler thick liquid; add water in order and proper auxiliary in a low speed, then put color and filler (generally we should firstly add something with large oil absorption), wash the meachine after putting the powder. Then seperate them for about 20 miutes in a high speed, until the fineness is qualified; of course, if you need sander, i think you only need sino-soviet differential powder material and non-obvious particles. Third: Paint mixing period: after making the color and filler thick liquid, reduce the roll speed into about 600 roll per minute, add emulsion and proper auxiliary, finally adjust PH and viscosity. Liquid solvent paint, pigment paste: Resin,solvent and pigment ---〉pre mixing---〉stick---〉grinding--〉stick--〉packaging, highlight varnish: Resin, solvent ----〉mixing ----〉stick ----〉packaging, sub-gloss varnish: Resin, solvent----〉mixing----〉matting agent,stick----〉packaging, colored paint: The primary colorant----〉Color matching by auxiliary color paste----〉stick----〉packaging, aluminum paint: Aluminite powder soaking----〉resin----〉colour modulation, lustre adjusting----〉stick----〉packaging, powder coat: Resin,filler,pigment,auxiliary---〉mixing---〉extrusion---〉cooling---〉smashing---〉sieving---〉 packaging.
Q:How many kinds of fireproof materials are there in the market?
A-level materials are the best which will not burn while the B-level materials are made of combustible materials which can burst into flames.
Q:What are the main components of refractory cement?
Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
Q:Are the rubber insulation materials are refractory materials?
It's not.
Q:Does the refractory material used in steelmaking all refer to refractory brick?
The refractory material used in steel making doesn't all refer to refractory brick, but also includes refractory castable. The foaming agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.
Q:what are the types of piping insulation material fire rating?
Pipe insulation material Fire rating: heat conductivity coefficient(at room temperature) 0.025 grade non-combustible Class A low temperature bending ≤ 5000 breaking elongation 5,000 specifications 5000 anti-bending strength 5000 compressive strength 5000 special brand of high use temperature -250 ~ 150 ℃ core material, phenolic foam, form, stratiform, shape,flake.
