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.

- Q: Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
- Porosity, volume density, water absorption, true density, thermal expansion, thermal conductivity and heat capacity.
- Q: What kind of material is refractory fiber?
- Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts. Besides, it has high temperature resistance and corrosion resistance which ordinary fibers don't have. As a fire retardant and thermal insulated material, it has been widely used in metallurgy, chemical, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
- Q: What is the classification standard of fireproofing material levels?
- the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. class B1: combustible?building?materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F
- Q: What are the specific steps of stirring the steel ladle castable?
- Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.
- 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.

- Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
- Q: what materials can make external wall fireproofing paint have the fireproofing effect
- Adding flame retardant or fire retardant materials can be fireproofing, which commonly referred to as the external walls of fire retardant coating or fire retardant coating. Principle: Fireproof paint itself is flame-retardant or non-combustible, so that the protected base material can not directly contact with the air in order to the ignition delay and reducing the burning speed; except that, it also has a lower thermal conductivity, which can delay the transfer of flame temperature to the protected base material; fireproof paint thermal can decompose non-combustible inert gas by heating to dilute the thermal decomposition of combustible gas in protected object, making it difficult to burn or slow down the speed of burning.
