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

- Q: What are the applications of refractory in petroleum?
- Petroleum industrial furnace has many varieties. Generally, it includes tubular with complex structure, whose use temperature is generally 500 to 600 degrees centigrade, sometimes may be 800 degrees centigrade. Petroleum gas contains hydrogen sulfide and solid particulate matter; first correct the answer of the first floor: It is not used in petroleum industry. As shown in the left picture, it is tubular heating furnace, appilied to metallurgical industry. Lined with lightweight insulation and wear-resistant layers, and resistant to wear and corrosion: 1; & nbsp, but the using temperature is not high; it is a thermal equipment in the oil refining process. High alumina refractory castable used for refractory layer. It is an important equipment of petroleum boiling catalysis and dissociation. You can choose light refractory bricks or refractory?castables; as shown in the right picture, it is catalytic cracking unit, and can bear pressure. Note; & nbsp: // f; & nbsp.hiphotos, fire-resistant plastic or refractory ramming mass has chemical corrosion and wear effect on lining; & nbsp, less than 1,350 degrees centigrade. The yse temperatures is up to 1,100 degrees centigrade.
- Q: What is the difference between wear-resistant material and refractory material?
- There must be difference. The requirements of refractory material are that it can be called refractory material when temperatures it can withstand are over 1570 ℃. Refractory material must have high strength. The specific value of refractory material is not clear.
- Q: What's the difference between refractory metal raceway and fireproof raceway?
- In terms of fire protection, fireproof raceway means that it is composed of the material with certain combustion performance and generally made of flame retardant or incombustible?material. While for the refractory raceway, according to GA 479-2004 "Fire Resistant Cable Tray", its most important properties are: Fire resistance of the cable tray should meet with the following requirements: The cable tray of I grade fire resistance should keep the working time more than 60min, of II grade fire resistance should keep the working time more than 45min, and of III grade fire resistance should keep the working time more than 30min. Hope this is helpful for you! Thank you.
- Q: What's the heat conductivity coefficient of fire-resistant material?
- 5～5 (Unit: W·m-1·K-1). The symbols are λ or K. Thermal conductivity and material properties Thermal insulation material generally is 0, and is related to organizational structure and working temperature. Thermal conductivity of the material refers to the heat transferred from from one plane to another plane in 1 seconds. Generally the thermal conductivity of fire-resistant material is 1. The larger the value is, the stronger the thermal conduction performance is. If the temperature of two planses differes for 1K, then the thermal conductivity is 03~1. The plane cover 1square meter.
- Q: Refractory factory grinding brick dust harmful to the body?
- Therefore, in the workshop work must pay attention to do their own protection.
- Q: What is the role of the vermiculite fireproof material?
- Apart from inflaming retarding, the materials covered with vermiculite has a lot of advantages including anti rust, waterproof, anticorrosive, wear-resisting, heat-resisting and the coating is armed with toughness, colorability, adhesiveness, fast-drying and luster.
- Q: What high-molecular polymers can be used as fire-resistant material binder?
- Lignin is the least expensive.
- Q: Which kind of furnace hearth refractory is better?
- Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica?bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
- Q: whether the aluminum silicate thermal insulation material is fireproof or not?
- aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
- Q: Why the corundum can be used as refractory
- Do you need white corundum Its main chemical element of corundum is the 99.3% aluminium oxide and it is sintered byelectric furnace, so it can be used as a refractory raw material, the other can also be used as grinding wheel. It is very useful
