Product Description:

Refractory Material/ Zircon Sands 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

Q:How many hours of the fire endurance time of the rock wool laminboard?
The fire endurance time of the rock wool laminboard is generally adout 1 or 2 hours.
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
Q:Why should graphitic refractory materials be used now that graphite can burn?
C is inactive in nature. Carbon will not burn unless the temperature is about 2000℃, so it can't be lit generally. Coal can be lit because it contains other combustible substance which ignite carbon indirectly. While graphite, carbon black, is more pure and dense than coal., so it is hard to oxidize.Their molecular structures are also different, just like diamond is harder than graphite.
Q:For refractory, what is critical particle size? Thank you.
For example, in refractory technology, if there is an express of equal to or lower than 0.008mm, 0.008 refers to critical particle size. The main criterion for judging performance of three major continuous casting is the major three normal temperature indexes (compressive strength and anti bending strength at normal temperature, apparent porosity and bulk density). Does this criterion have any defect? How to do multiple test if high-temperature index introduced? Carbon bond is one of the three major castings. How does it form? What do you think of it? Hope someone explains it for me. Thanks a lot!
Q:What refractories are used in various parts of the blast furnace.
Blast furnace from top to bottom has the throat, hearth staves, waist, bosh, hearth and furnace bottom. the specific structure is as follows: The throat is the first to be affected by the impact and abrasion, generally use high-density alumina bricks. the upper and central portion of temperature furnace is only 400 ~ 800 ℃, the area with high alumina bricks and silicate bricks. The lower part of furnace is subject to erosion and dust erosion alkali metal vapor due to high temperatures, it is required in such case to use high quality clay brick,high alumina brick,carborundum brick,corundum brick that is slag resistance and alkali resistance, temperature resustant and wearproof. Furnace bosh temperature reached 1400 ~ 1600 ℃, serverly eroded by slag,vapor, flush. so we use carborundum brick and reaction-bonded silicon carbide brick. Bosh temperature reaching1600 ~ 1650 ℃, using alumina brick, corundum brick or silicon carbide brick. the temperature of Hearth near the upper portion of the outlet zone at 1700 ~ 2000 ℃, use of silicate bricks and corundum castable graphite filler, silicon carbide bricks. In 1450 Silly twitch bottom temperature sealing die of hunger slander bet phoenix astringent preserved Grade ~ 1500 ℃, use of graphite bricks and microporous carbon bricks, now use more corundum brick, corundum mullite brick and synthetic mullite brick. x26lt;P class x3d "share-btn"x26gt;
Q:Who knows how to divide the building fire grade and fire resistance grade?
I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.
Q:What kind of refractory decorative board has good quality?
Formica, Grignard, Wilsonart, Yami Home, Germany Board and Priscilla Board are all good choice. They are the high-end brands in fireproof panel. Hope it is helpful to you.
Q:What is the difference in the nature between the refractory material and thermal insulation material
thermal insulation material is a material which has a strong impedance to the heat flow. the nature of the material requires that the material can isolate the delivery of thermal, and the low heat conductivity coefficient and expansion coefficient of the non-metal material.refractory is good in heat resisitance and chamical erosion but not high temperature resistance. Requirements on nature is still in high temperature.
Q:What are the fire resistance ratings of the glass partition?
When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer. The partitions in the usual sense are walls that have a distance to the ceiling. The fixed partitions directly touches the ceiling are partition walls which should be required in accordance to the specifications of walls. If the partition is far from the ceiling, the fire protection requirements are relatively low. Partitions which combustion performances are no less than B1 level are safe enough, while partitions of places such as shopping malls have to reach A-level in terms of combustion performance.
Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?
gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.
