Product Description:

High Purity Refractory Material/ Zircon Sands and Zircon Flour

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.

3.Main usage of Zircon Sand and Zircon Powder

The zircon sand is mainly used for fireproof materials (commonly called zirconium fireproof materials such as corundum bricks and zirconium fireproof fiber), sand for casting mould in casting industry (precision casting sand) and fine enamelware. In addition, the zircon sand is also used in the production of glass, metal (zirconium sponge) and zirconium compounds (zirconium dioxide, zirconium oxychloride, sodium zirconate, zirconium potassium fluoride, zirconium sulfate, etc.).

Q:What is the appropiate thickness if fire resistant time for ultra thin steel structure coating is 2.5 hours?
A level fire resistant steel structure building steel column cannot be constructed with super thin steel structure fire retardant coating, because the ultra thin steel structure fire retardant limit is less than 3 hours. Thin fire retardant coating for steel structure is water borne fireproof coatings painted on the surface of steel structure. It will form carbonized fireproof heat insulation protective layer to insulate oxygen and delay the speed of heating steel structure when it catches on fire, avioding the rapid temperature rise of steel structure and increasing its fire resistant limit. Fire resistance performance: The 2mm coating ≥ 60min, 3mm 100min.
Q:How to detect the acid resistance of refractory? Is there any standard? Thank you
What material it is. There are many kinds of refractory materials, and I basically understand all petrochemical refractory.
Q:Does anyone knows which company produces the better refractory materials?
I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。
Q:Do you know where I can buy refractories?
A Address of Guangzhou Lingnan Refractories Co., Ltd. : No.1069 Guanghua 1st Road B Address of Guangzhou Aolian Refractories Co., Ltd. :
Q:What does fire-resistant insulation coating have?
What is the most famous is that grade A is incombustible thermal insulation material. W W inorganic active wall insulation materials, cement foam insulation board, vitrified micro bead thermal insulation mortar, rock wool board, glass wool board, foam ceramics, etc.
Q:What is refractory brick?
Capability1. Refractory brick is also known as firebrick. It is faint yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.
Q:I want to know what is the slim in the refractory bricks
lining brick and refractory clay in the teeming ladle; high alumina brick, high alumina lining brick and high alumina refractory mortar can make cement kiln and glass melting furnace in the building materials industry for anti-slide. Taiyuan in Shanxi province is the famous place of origin; hard paste in the refractory clay is used as blast furnace refractory: // b, in agriculture as a fertilizer high alumina clay is also used in oil wells, which generally do not dip in water; accounting for 2/3 of abrasive products in the metallurgy, hard and semi-hard clay can be manufactured as ceramics for daily use. what you said should be slime. High-alumina clay can be resistant to high temperature after calcination! Refractoriness refractory clay refers that the refractoriness is more than 1580 ℃ with greater hardness and specific gravity and high refractoriness. except higher refractoriness, such as aluminum sulfate, the dosage accounts for about 70% of refractories; refractory clay and high alumina fused cast brick are widely distributed in China.
Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:What kinds of refractory will be used in kiln of sintering ceramics?
If it is ordinary ceramic, you can use ordinary clay bricks and high alumina brick, adding calcium silicate board, the insulating brick and cotton fiber.
Q:Can you tell me the classification of fireproof sealing material.
Fire blocking is to use fire blocking material as partition between cable threading hole and electric hole. Its role is to prevent the cable itself catacausis or outside naked light make the fire spread to achieve the purpose of protecting the safety of personnel and equipment. The principle of fire-proof sealing is plugging material acting as bloating heat absorption and heat insulation. Fireproof sealing material in current market include: fire-proof sealing plate, foam sealing materials, flame retardant module, flexible organic plugging material, inorganic fire sealant, plugging and fire package, etc. The wide usage of fire-proof sealing material in building construction can ensure the fire flame and high temperature flue gas not to extend another fire partition tendril.
