Product Description:

High Grade Refractory Material/ Zircon Sand and Zircon Powder Good Quality

1.Structure of Zircon Sand and Zircon Powder

We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. We are offer zircon sand With Below Mention Descriptions: ZrO2 65 - 67 %. Zircon is a remarkable mineral, if only for its almost ubiquitous presence in the crust of Earth. It occurs in igneous rocks as primary crystallization products, in metamorphic rocks and in sedimentary rocks as detrital grains. 
Further, the mineral due to hardness, durability and chemical inertness, zircon persists in sedimentary deposits and is a common constituent of most sands.

2.Main Features of Zircon Sand and Zircon Powder

The zircon sand is mineral mainly containing ZrSiO4.

The pure zircon sand is a kind of colorless and transparent crystal and shows different colors such as 

yellow, orange, red and brown due to different origins, types of impurities and content, and also coexists in

 beach sand with ilmenite, rutile, monazite,etc. the zircon sand can be separated  benificiation process. 

 

3.Main usage of Zircon Sand and Zircon Powder

Shell moulds and cores for casting gray, Malleable and nodular cast iron, alloyed steel and  carbon steel, non-ferrous metals, etc

Q:what's the fire endurance of fireproof panel?
Fire endurance of fireproof panel is 3 hours, for example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. Fireproof board, also called fire endurance board, scientific name is thermosetting resin impregnated paper laminated wood.
Q:How long is the duration of fire resistance of hollow glass magnesium board
Glass magnesium board is non-combustible board with excellent fire resistance ability, the continuous burning time of flame is 0, non-combustible at 800℃, no flame at 1200℃, achieving the highest level of fire retardant level A1; Partition System cooperated with high-quality keel can endure fire for more than 3 hours. In the process of combustion, a large amount of heat energy can be absorbed, and the temperature of the surrounding environment will be delayed.
Q:How long can gypsum board endure fire?
General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. It is clearly stipulated in Clause 2.0.4 of "Specification of Fire-resistance of Decoration Design in the Interior of Buildings" that "gypsum board, mineral wool board and acoustic board whose combustion performance reach at B1 grade installed on steel joists can be used as A-grade incombustible materials. Although the gypsum board is non-combustible material, we need to examine materials' stability in the face of fire and their fire retardant limits besides exmine their fire prevention standards. Fire retardant limit refers to the ability and time that materials can resist fire when encounting fire and taking palce changes.
Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:What is the classification standard of fireproofing material levels?
the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion source. class B1: combustible building materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F
Q:Who knows about the fire endurance of sintered shaly hollow bricks?
Sintered shaly hollow bricks of Chu area have high intensity. The average compressive strength of them is up to 15.8, which matches with M7.5 cement mortar that has advantages of low water absorption, and good anti efflorescence performance. The fire endurance of sintered shaly hollow bricks should not exceed1050 degrees otherwise they will burn excessively. I, actually, think that the temperature should be controlled within 980 degrees. I hope my answer may help you.
Q:What are the main characteristics of the sic refractories?
1. The usge temperature of silicon carbide refractory is generally 1760 ℃ 2. The silicon carbide refractories can withstand the dramatic changes of temperature and have a good thermal shock resistance performance. To prevent the cracking or breaking of lining refractories. 3. Under the conditions of high or low temperature, it can withstand a certain compressive stress. 4. Under the conditions of high or low temperature, it can withstand friction. 5. It can withstand the huge hydraulic pressure or buoyancy of the metal. 6. It can also withstand the effect of furnace gases to prevent the infiltration of other refractories and reactions.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
The ceramics and refractories are different with the porcelain ceramic with high temperature of 1300℃ as household porcelain refractory. The porcelain refractory material of 1450℃ as the same as the aluminum oxide, kaolin, refractory clay and other raw materials demand the deployment ratio of the raw material the same as the temperature.
Q:What are the requirements of refractory temperature of refractory brick?
Refractory bricks furnace pipe material is generally divided into two types, namely, shapeless refractory material and shaped refractory. Shapeless refractory material, also known as castable refractory, is hybrid powder material made up of many kinds of aggregate or aggregate and a kind of or many kinds of binders. It must cooperate and evenly stir with a kind or many kinds of liquids during use and has strong mobility. Shaped refractory material usually refers to refractory brick whose shape has standard rules. It can also be processed temporarily during cutting according to requirement. Refractory brick, called refractory brick for short, is refractory material made by firing refractory clay or other refractory raw materials. Faint yellow or brownish, it is mainly used in building smelting furnace. It can resist 1,580 ℃-1,770 ℃ high temperature.
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
You mean furnace lining or ladle lining? Generally magnesia is used as furnace lining, but heat preservation should be practiced when shut down, or brasque would crack. Surly you can employ existing furnace lining which is sold in Tianjin, a little bit expensive, the average lining could be used for 300 furnaces. The furnaces made by magnesia myself break down after 40 furnace were finished. What I referred is a furnace weighing 2 tons, as for a bigger furnace, the existing brasque would be OK. What is the difference between furnace lining and ladle lining? Can you give me more detail about the materials of making a furnace weighing 2 ton? Why others can burn 80-90 furnace with 0.7-ton furnace; over 200 furnaces with 2 ton? What are these ingredients? What I know is just magnesia, magnesium borate, and together with boric acid, they also have many types, which one should I use? Thank you!
