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 are the technical requirements for refractories?
To put it simply, physical indicators are pores, volume density, pressure resistance, slag resistance, thermal shock resistance, foot expansion coefficient, thermal conductivity, oxidation resistance and so on. If it is castable, the indicators are mobility, water rate, setting time, and anti bending strength. If it is coating mix, the bonding strength should be checked. Chemical indicators are loss of ignition and the content of aluminum, magnesium, silicon, calcium, chromium, titanium and carbon.
Q:Can you tell me the classification of fireproof sealing material.
Inorganic fireproof plugging material includs: organic fireproof plugging material, fire bags, warfare, fire collars, fire belt, fire prevention sealing strip, flexible fire protection coil, fireproof glue and so on. I hope my answer can help you. Thank you!
Q:What is refractory material?
Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?
You can try the following way to give a brief introduction of the fire rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level: Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1). Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
Q:what is the fireproofing material of engine room? who knows it ?
machine room fireproofing materials include: Inorganic binder: The main material includes sodium silicate, gypsum, phosphates, cement,ect.; refractory mineral filler: aluminium oxide, asbestos powder, calcium carbonate, perlite, cornstarch, ect.; nonflammable organic resin: it mainly includes polyvinyl chloride, perchloro-ethylene, chlorinated rubber, neoprene latex, epoxy resin, phenol resin, ect.. nonflammable fireproof addictive: it mainly has phosphorus, halogens, nitrogen organic compounds (chlorinated paraffins, tributyl phosphate,deca-brominated diphenyl ether), and boron series (boric acid, zinc borate, aluminium borate), antimony system, aluminium series, zirconium system, etc. inorganic compounds.
Q:What's the B grade fireproofing material?
Grade B: rubber and plastic, extrusion molding, polyphenyl, PEF. organics, extruded sheet, polyphenyl board, phenolic resin. Hairong modules (thermal insulating and fireproof material) can reach grade B1 in fireproof performance.
Q:How should refractory cement be used?
Refractory cement is very easy to use. Add some water and mix, and it will harden. Generally there is no need to add other binding agents, but you can add some refractory aggregate and powder. If you use only refractory cement, it will generate a lot of cracks after high temperature. Generally refractory cement can withstand temperature of about 1300 degrees.
Q:What kind of refractory materials should be used for the intermediate frequency furnace to smelt manganese?
I am not quite clear. But you should take two aspects into consideration, namely, no pollution and strong durability.
Q:What are the physical properties of refractory material?
The mechanical properties of refractory material include compressive strength, volume density and sclerosing, slag resistance, elastic modulus, thermal shock resistance, oxidation resistance, bibulous rate, fluidity, resilience, bond strength and slump, electrical conductivity, specific heat, heat capacity, the impact strength, linear change, torsional strength, stomatal aperture distribution, resistance to acid, etc. The use performance of refractory material include refractoriness, thermal emissivity, condensation, porosity, coefficient of thermal expansion. Thermal properties of refractory material include thermal conductivity, temperature conductivity, plasticity, the hydration resistance, creep performance. The physical properties of the refractory materials include structure performance, mechanical properties, shear strength, load softening temperature, CO erosion resistance. The structure properties of the refractory materials include porosity, alkali resistance and sintering. The operating performance of refractory material include consistency, tensile strength, the use performance and operating performance, wear resistance, bending strength, thermal properties.
Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
