Product Description:

Refractory Material/ Zircon Sand and Zircon Flour 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

1 Tiny, round, solid ball shape provides greater surface area for improved performance and dispersion in its application

2 High refractory rating, lower specific gravity rating, and higher service temperature produces greater yield

3 With lower bulk density, it offers better air permeability for better performance as a result of its overall physical characteristics

4 Lower thermal expansion rate and thermal conductivity produces better results in intense heat environments

5 Standard particle size within each grade is ideal for specific applications

6 Raw material is easily reclaimed multiple times by dry method

7 Physical characteristics produce a lower breakage rate during dry crushing

8 Ceramsite sand is a cost effective, single sand application; no need to mix with other sands

9 Ceramsite Sand is environmentally friendly, reducing pollution and reusing raw materials

 

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'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:What kind of materials are needed to make refractory bricks?
Who knows what kind of materials are needed to make refractory bricks?
Q:Introduction to refractory material
Refractory material refers to inorganic non-metallic materials with refractoriness of no less than 1580℃. Refractoriness refers to the centigrade temperature of refractory cone sample in the case of no load when resisting high temperature without softening. But the refractoriness alone cannot descript the refractory material, thus 1580℃ is not absolute. Now refractory material is defined as material used in high temperature allowed by its chemical properties. Refractory material is widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate and power industrial area, of which the application in metallurgy accounts for the largest part of 50% ~ 60% of total output.
Q:how to classify Insulating Refractory ?
General materials have test reports, where fire rating is labled.
Q:How long is the duration of fire resistance of autoclaved flyash-lime bricks?
The compressive strength of the autoclaved flyash-lime bricks is generally higher, which can reach 20MPa or 15MPa, at least 10MPa, and it can withstand the 15 freeze-thaw cycles. Besides,fly ash brick is a kind of potential active hydraulic material. In the humid environment, it can continue to produce hydration reaction and make the internal structure of the brick is more dense, which is conducive to improvement of the strength. It is found in experiments and many investigations that sample some carbide which is used for foundation, plinth and drains, after one or twenty years of freezing thawing and wetting drying, some bricks have been completely carbonized, but strength is not reduced, increased instead. This is one of the merit of autoclaved flyash-lime bricks.
Q:Does anyone know the fire endurance of steel stud partition?
Indeed ① Dragon Brand gypsum board fire-resistant partition: Its fireproofing extreme time is 4 hours, suitable for firewalls of a variety of public buildings, public exit passageway and other partitions, which meets the first level of fire protection standard ② fireproofing and pressure-resistant partition: Refers to the partition which can withstand momentary gas shocks of over 1200pa , mianly used for the room partition with inert gas fire-fighting needs, such as equipment rooms. The pressure-resistant degree of fireproofing and pressure-resistant partition of Beixin Building Materials can be up to 4800Pa, especially suitable for high-rise fireproofing.
Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
Explain that where you use it for and what requirements you have. Follow-up: I use it in metallurgical furnaces with the features of strong stirring and acidic residue.
Q:Which industry does refractory belong to? Does it belong to construction industry?
It belongs to material, and after all, more than 60% refractories are used in metallurgical industry. If you insist on classifying it, it belongs to supporting industry of metallurgical industry. Refractory industry itself is independent.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
They are not the same. If you say the ceramic fibers, they have some common points because the ceramic fiber is one of the refractory. It is belonged to the lightweight refractory which can be considered a new type of refractory with the main ingredient of aluminum silicate (including aluminium oxide and silicon dioxide).
Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?
Add some hair and slags, or it will crack before calcination.
