Product Description:

Zircon Sand and Zircon Powder High Performafce for Refractory Use

1.Structure of Zircon Sand and Zircon Powder

This product is produced with the advantage of  good high temperature stability of zircon sand.It has the characteristics of  high strength ,high density and high refractoriness under load .So,this product has good performance of spalling resistance,abrasion resistance, liquid glass erosion resistance and other industrial slag erosion resistance.  

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. The 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.

Q:What is glass furnace used high-grade refractory materials?
Corundum brick, such as alumina hollow ball brick. In addition, in the key parts of the glass furnace needs to use chromium zirconium corundum material. I'm salesman of zibo lei bao refractories company. The softening temperature of corundum mullite brick is 1500 degrees. So glass melting furnace needs to use refractory materials which high temperature resistance is more than 1600 degrees.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
Q:How many kinds of refractory materials are there in the EI?
I suggest that you contribute articles to foreign SCI journals for the odds are better, and generally the articles that fill the bill will not be rejected. The traditional refractory materials can contribute to EI journal. If being rejected by EI journal, you can also contribute to Russia's journal Industrial Ceramics and Refractories. I didn't contribute to the Journal of Wuhan University of Science and Technology, the receiving cycle is almost 3 to 4 months. Though the impact factor is low, domestic EI journal is not so good, it is still SCI journal. This is my own experience, please take my advice. The best journals are the Journal of the American Ceramic Society and the Journal of the European Ceramic Society, I heard that they are not bad. But the best domestic EI refractory material journal is the Journal of The Chinese Ceramic Society. It is very long, but if it belongs to your university, it is another pair of shoes. Journals now all want to have materials about functional ceramics, and they don't want Chinese articles, if your English is not well enough, you can choose Ceramics International and Japan Ceramics but they have strict manuscripts reviewing standards.
Q:Is the refractory reached British BS standard and used for cables in China at present ceramic silicone rubber?
The texture should be designed according to the British relevant BS standard; crosslinked polyethylene or ethylene propylene rubber under 6600V to 19000 / 33000V is not necessarily ceramic silicone. The rated voltages of a small amount of smoke and corrosive gases from 3800 & # 47 when the BS 7835-2000 is affected by fire.
Q:who knows the fire endurance of fireproof coating?
It's fire endurance is 3hours. Fire endurance test of certain building components showed by standard time temperature curve from the starting of fire to lose of supporting capabilities or its integrity or fireproof property. unit time is one hour.
Q:What are grade classifications of the external walls for fireproofing?
1. The thermal insulation material of level A combustion performance: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See the 2009 edition construction technical measures 4.3.6 Level A insulation material is only for fireproofing, but its thermal insulation performance is not better than organic XPS \\ EPS and other materials. I feel the best insulation materials should be modified phenolic board, which can keep insulation and fireproofing, but the comprehensive unit price is very expensive.
Q:The development prospect of fire-resistant material
Concrete has a broad employment direction while refractory material is not in popular demand. But if you do well, you are one of ethe experts.
Q:What is the limit of fireproof rolling shutter?
According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.
Q:What is the particle size of boron carbide for refractories?
2 floor is right, support, learning! But what do you mean by boron carbide (d90=36.5, m)?
Q:Why do magnesium oxide refractory bricks can be made into refractories?
Nature: It is loose white powder and tasteless. When exposed to the air, it is easy to absorb moisture and carbon dioxide. It is dissolved in acid and ammonium salt and insoluble in water and ethanol, with the melting point of 2800 and the boiling point of 3600. The magnesium oxide has high fire-resistance insulation properties, with high melting point . It can be said to be non-combustible materials.
