Refractory Material/ Zircon Sand and Zircon Flour/ Powder

1.Structure of Zircon Sand and Zircon Powder

Zircon Sand, also known as Zircon, is a Chemical Compound, a Silicate of Zirconium, andits corresponding Chemical Formula is ZrSiO4. It occurs in nature as the Zircon, a Silicate Mineral. Ore is mined from natural deposits and concentrated by various techniques. It is separated from sand by Electrostatic and Electromagnetic methods. It can be made by fusion of SiO2 and ZrO2 in an arc furnace. It is usually colorless, but impurities induce various colorations. It is a fine white mineral powder that is chemically inert and stable.It is insoluble in water, acids, alkali and aqua regia. The tiny, round, solid ball shape of Zircon Sand provides a greater surface area for improved performance and dispersion in its application. It is also sometimes known as Zircon Flour, Zircon Powder, or Zirconium Silicon Oxide. Zircon is the generic name for Zirconium Silicate; the trade names are different (for example, Zircopax, Zircosil). It is used as an ingredient for its functional properties in several Industries.

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 long is the duration of fire resistance of autoclaved flyash-lime bricks?
How long is the duration of fire resistance of autoclaved flyash-lime bricks?
Q:What are the materials of class A fire resistant window?
The filling materials of steel, wood frame should be non-combustible materials. Fireproof glass can use qualified products that do not affect the fire window fire resistance performance, whose light transmittance should be no less than 75% that of the commom sheet glass with the same layers. Sealing materials between the frame and fireproof glass should be nonflammable materials. Hardware fittings should be fixed supporting products that pass the test.
Q:What high-molecular polymers can be used as fire-resistant material binder?
Lignin is the least expensive.
Q:What substitutes are available for high-end refractories in addition to zircon sand?
Natural ore, synthetic raw materials such as industrial synthetic mullite, etc..
Q:What are fireproofing materials?
1. With the tape made by double-coated flame-retardant and chemical defense surface adhesive and that only occurs charring with no melting drops and maintains good strength when meeting with fire as main material, and by the laminating-sewing-pasting process, clothing body and gloves are made and equipped with flame retardant, chemical defence, voltage resistant, and puncture resistant boots, the clothing assembly is constituted. 2. They are usually asbestos. Some of them have better quality and are made by wiredrawing of aluminum zirconium and silicon mixtures, and of course others are directly manufactured with some natural objects. 3. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. Coatings are usually those with fine powder, high density and good sealing. 4. Phenolic foam board can meet the requirement and its test temperature can reach up to 2000℃ under which it has no molten droplet but good integrality. Thermal Conductivity: 0.03W/(mk). It is non-flammable, non-toxic and smokeless! 5. The hollow ceramic micro-bead is good in thermal insulation and fire-retardance.
Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
STP has a certain chance to self-destruct. After the sealing layer is damaged, the property will be bothered. When filling the foam glass, burst foam cement and low-strength glass fiber, the structural requirements are very high with big spraying limitations. As everyone knows that rock wool absorb organic matters, and the government do not allow us to use self-insulation, so it is not the mainstream with too low adoption rates. In fact the owners shouldn't worry about this problem. Since the developers have installed it for you, it is useless to worry about it. The other is that for those who want the original balcony closed up, if you want to shovel the original balcony wall insulation, you must pay attention to ask the construction team before you start. Because it is common that the cold bridges formed thereby will cause water seepage and moisture condensation in the balcony.
Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
Q:Development trend of refractories
Facing the survival and development of refractory industry challenges in many aspects, serious: 1, the user industry due to the progress of science and Technology (such as iron, iron and steel industry in the direct reduction furnace, to reduce casting, slag splashing etc.), reduce refractory material consumption; 2, refractory material environmental protection and ecological requirements; 3, users of the product quality and cost requirements; 4, users risk transfer, refractory material, the design requirements of the liner construction, maintenance services, and even provide construction equipment; 5, between refractory enterprises and personnel dispute price; 6, due to the industry downturn in some countries, the decline in refractory material and the lack of education, lack of young professionals; 7, resource depletion and other raw materials.
Q:What are fire ratings of wall thermal insulation material?
1.thermal insulation material with grade A combustion performance: YT inorganic active insulation material for wall thermal,rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2.thermal insulation material with grade B combustion performance: Extruded polystyrene board(XPS)after special treatment/polyurethane(PU) after special treatment, phenolic aldehyde,gelatine powder polyphenyl granule, etc. 3.thermal insulation material with grade B2 combustion performance: Molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
