Product Description:

Refractory Materials/ Zircon Sand and Zircon Flour/ Powder

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

 

3.Main usage of Zircon Sand and Zircon Powder

  • 1)80-120M zircon sand is used in investment casting, the processing is called dipping 
    2)It can enhance the shell`s thickness 
    3)It is specialize used in inner layer being mixed with silica sol.

  • High temperature applications. Primary source for investment casting shell molds, foundry cores,

  • metal chills, ladle brick, welding rod coatings, abrasive cleaning, ceramics, glass, chemical, 

  • refractory bricks, abrasive & mold washes, solid oxide fuel cells and nuclear power plants.

Q:Who knows the external wall thermal insulation materials fire rating requirements?
The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
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:Is refractory material harmful to human body?
Chromium oxide is poisonous in alkaline environment, and the gas produced by heating of asphalt, asphalt and refractory material is poisonous............ Go to the real estate company experts, I can think of these
Q:Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
Different fire resistant ratings of buildings require different fire endurance of different elements of buildings. According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level.
Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:What are the meanings of azs, 34% and ec in fused brick?
The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
Q:What are the types of refractory sealant?
Hello: I'm glad to help answer your questions! Measure fireproof material is high polymer plastic seal material which is used for seal. It has a dual performance of both sealing and fireproofing. It can be applied for fire protection construction of metal pipes, thermal insulated pipes and construction juncture. Fire-resisting sealant has an expansion rate of greater than 20% and it is resistant to nuclear radiation, LOCA, detergents, and it has radioactive decontamination performance. It has a durability of more than 40 years; It is free of halogen, sulfur and other toxic matters, watertight, anti-smoke, corrosion free, safe and environmental-friendly. It gives off no toxic smoke and is efficient in inflamming retardancy which is easy to construct. I hope my answer will be helpful to you.
Q:How to hang the suspended brick in the refractory masonry?
First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
Q:Urgently!! Refractory problems, online, etc.
I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?
Q:The structure of refractory material
