    Hollow Fly Ash Cenosphere for Casting/Construction/Oil Drilling/Paint/Coating/Refractory China Manufacture

    Hollow Fly Ash Cenosphere for Casting/Construction/Oil Drilling/Paint/Coating/Refractory China Manufacture


    Cenospheres is a kind of fly ash hollow ball that can float on the surface of the water. It is grayish-white, thin and hollow, light in weight, with a bulk density of 250-450kg/m3, a particle size of about 0.1 mm, a closed and smooth surface, and a small thermal conductivity. Refractoriness ≥ 1700 ° C, is an excellent insulation refractory material, widely used in the production of lightweight castables and oil drilling. The chemical composition of the floating beads is mainly composed of silica and alumina and it has various functions such as fine particles, hollow, lightweight, high strength, wear resistance, high-temperature resistance, thermal insulation, insulation and flame retardancy every industry.

    3.Characteristics :
    (1). High refractoriness:
    the main chemical composition of the floating beads is silicon and aluminum oxide, wherein the silicon dioxide is about 50-65%, and the aluminum oxide is about 25-35%. Because the melting point of silica is as high as 1725 degrees Celsius, the melting point of aluminum oxide is 2050 degrees Celsius, which are all high refractory materials. Therefore, the floating beads have an extremely high degree of refractoriness, generally reaching 1600-1700 degrees Celsius, making them excellent high-performance refractories.
    (2). Light-weight:
    thermal insulation; floating beads wall is hollow, the cavity is semi-vacuum, only a very small amount of gas (N2, H2, and CO2, etc.), heat conduction is extremely slow. Therefore, the floating beads are not only lightweight (weight: 250-450 kg / m3), but also excellent thermal insulation (thermal conductivity normal temperature 0.08-0.1), which laid the foundation for its role in the field of lightweight insulation materials.
    (3). High hardness, high strength:
    because the floating beads are made of silicon-aluminum oxide mineral phase (quartz and mullite) hard glass body, the hardness can reach Mohs 6-7, static pressure strength is as high as 70-140MPa, true The density is 2.10-2.20 g/cm3, so the floating beads have high strength.
    (4).the insulation is not conductive:
    generally, the resistance of the insulator decreases with the increase of temperature, the floating beads are opposite, the resistance increases with the increase of temperature. This advantage is not available in other insulating materials. Therefore, it can be made into an insulating material with excellent performance.
    (5). fine particle size, large specific surface area;
    floating beads naturally formed particle size of 1-250 microns. The specific surface area is 300-360g/cm2, which is similar to cement. Therefore, the floating beads do not need to be ground and can be used directly. Fineness can meet the needs of various products.

    4. Other Application of Aluminosilicate Microspheres

    As has already been noted, aluminosilicate microspheres (cenospheres), due to their special properties, have a variety of applications:

    • Building and finishing materials: filler for compressed concrete (paving, paving slabs, and decorative elements)
    • Construction of decorative structural sections and face-mounted attachments; artificial stone for interior and exterior finish of buildings;
    • Automotive and the aviation industry: a filler for the production of composites, repair putties, and primers, compositions for the production of tires, bumpers and panels, sound dampening materials, light blade propellers, trim elements, etc.
    • Manufacture of abrasive tools: highly porous grinding wheels featuring closed design and high performance;
    • Compositions for surface protection against adhesion of weld spatter in the manufacture of welded complex-shape steel structures;
    • Fire-resistant filling for steel casting molds;
    • Production of non-slip compositions for the manufacture of heels and soles for footwear;
    • Furniture:a filler for the production of furniture moldings; creation of layers, which float on the surface of the oil to provide the reduction of vaporization.

    5.Specifications:
