Product Description:

Brief introduction of calcined mullite :

 

calcined mullite can be divided into shaped refractory products(Such as: Refractory brick ,Fire clay brick,High alumina brick, Heat insulation brick,Ceramic fiber products ect) and unshaped refractory materials(Such as:Refractory castable, Plastic refractory, High temperature refractory mortar ect), Widely used in metallurgy, petroleum, chemical industry, Cement, Glass, Casting,carbon,building materials, machinery processing, military, etc.

 

Refractory raw material of calcined mullite : The chamotte, Calcined flint clay, Calcined kaolin, Sintered mullite,Bauxite,flint clay, aggregate, fused mullite

 

 process of calcined mullite :

Made from the natural high quality bauxite, our product is through multi-level homogenozaotpm and then calcined at about 1750 degree. it possesses many good characteristics such as high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and good resistance to cheamical  corrosion, it is an ideal raw aterial for the following refractory products like a variety of shaped and unshaped refractories, advance ceramic asanitary ware body, precision casting models and so on.


Application of calcined mullite  :  metallurgy, petroleum, chemical industry, building materials, machinery processing, military, etc of thermal technology equipment.

Q:What is the quote of fireproof and soundproof materials used in KTV?
acoustic material, aluminum foil glass wool, sound-deadening material, glass wool, cinema / KTV dedicated glass wool: The classification of glass fiber products: The category of glass wool felts: The level of insulation cotton: A-level brands: New applications: The origin of GB/T13350-2008: The coefficient of thermal conductivity(room temperature): 0.035 bending at low temperature≤: 0.02 elongation at break: ≤80kPa flexure strength: ≤120kpa Compressive strength: ≤150kpa application temperature: 700 Core material: The shape of glass wool: Fibrous shape: Coil Specifications: Complete quote is 23 Yuan per cubic meter. glass wool board, KTV sound insulation core material: The shape of glass wool: The level of rectangular glass wool: A-level non-combustible brands: Kunnai material: The origin of glass fiber: Guangzhou, Shijiazhuang, Wuhan, the quote there is 8.8 Yuan per cubic meter.
Q:What's the refractory material in common use currently?
According to its category, raw material of basic refractory: Mainly magnesite (magnesia), dolomite, lime, olivine, serpentine, high alumina material (sometimes neutral); main neutral raw material: chromite, graphite, silicon carbide (artificial).
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
Q:What are the differences and connections between softening temperature of the refractory under a fixed load and thermal resistant creep property of the refractory?
The result of refractoriness under load is temperature while the result of creep is percentage of deformation. Refractoriness under load and creep can be tested by an instrument. Refractoriness under load reflects the temperature in which the deformation reaches a certain degree under the condition of load. Creep reflects the deformation refractory has under the condition of constant temperature and load. Both refractoriness under load and creep are important criterion for the operating temperature of refractory.
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:Is fireclay poisonous?
Refractory materials are typically oxides, alumina, magnesium oxide and aluminate cement and etc, which are non-toxic.
Q:What does refractory mean?
Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.
Q:What are the use of fire-resistant material and admixture?
Generally speaking, there are several admixtures: 1. Water reducing agent. It can ensure basic refractory castable flow value and significantly reduce its water mixing amount sodium hexametaphosphate and sodium tripolyphosphate 2. Plasticizer. It can increase plastic refractory mixture and enhance the ability of bentonite clay mud material stress strain 3. Gelling agent. It can make the colloidal solution (or suspending liquid containing solid particles condensed gelling agent 4. Dispergator. It can turn condensation or reunion colloidal particles (particles) into sol or uniform dispersion suspended particles and make the thick colloid free stream sol said scattered coagulant peptizer 5. Coagulant. It can shorten the stereotypes refractories condense sclerosis NaOH Mars between aluminum hydroxide, etc. 6. Retarder. It can delay the stereotypes refractories condense sclerosis between citric acid tartaric acid, etc. 7. Delayed coagulant. It can make setting fire-resistant materials contain binder by set out the condensation hardening effect between calcium aluminate cement, etc. 8. Foaming agent. It can reduce the liquid surface of power to produce uniform stability as rosin soap bubble resin fat saponin and so on. 9. Antifoaming agent. It can make fast setting fire-resistant material mixing or shock in produce bubbles escape alcohol fatty acids, such as 10. Shrink agent can reduce or prevent the refractory materials used to produce contraction type heating said silicon powder stabilizer or volume expansion agent, etc. 11. Preservative. It can keep setting fire-resistant material stored on construction performance change or change oxalic acid citric acid, etc. 12. Inhibitors. It can inhibit stereotypes refractories ingredients contain iron or iron compounds and acidic reaction caused inflation to produce hydrogen bond CrO3 diacetone alcohol, etc. I hope it can help you.
Q:Does refractory belong to metallurgical auxiliary materials?
Refractory includes metallurgical auxiliary materials.
Q:What is the role of the vermiculite fireproof material?
The vermiculite fireproof slate is widely applied to construction, shipbuilding, metallurgy, electric power, aerospace and other fields by foreign countries. Vermiculite slate can be applied to furniture, firewall, ceiling, and can be used in the fire fighting access, coated steel, coated pipeline, real flame fireplace in the lining board, wall partition. It is characterized by non combustible, non melting, resistance to high temperature; permanent thermal insulation; sound insulation, non-toxic, smoke-free, green environmental protection; resistance to impact, good dimensional stability and durability of the excellent anti fungal infestation. It can be sawed, nailed, planed, drilled, it can be easily installed and constructed.
