Principal technological scheme of production
Description:
Porous glass-ceramic filler is a totally inorganic foam closed cell on the basis of vysokokremnezemnstogo (85-90%) glass phase with crystal inclusions of quartz.
Ecological purity of the material and technology allows to certify structures, materials and building technology “green standards”, which in itself increases the assessed value of buildings and energy efficiency to meet the so-called “zero” or “passive” houses.
Ceramic porous filler can be produced in two product forms:
– in the form of spherical porous granules from 0.25 to 16 mm. Bulk density of 160 – 500 kg/m3 – used as a placeholder for sobolevka insulation and structural heat – insulating concretes (composites), allowing to provide the requirements of SNiP 23-02-2003 “Thermal protection of buildings” for insulation. Raw granules can be a product, since the thermal effects increase in size in 5 – 6 times and can be delivered to the place of consumption as a semifinished product;
– in the form of plates or blocks with a density of 200 550 kg/m3 – used as insulation in wall constructions (insulating facades, floors, interior trim, pipeline insulation) in timber frame constructions, including the construction of the sandwich panels.

Advantages:
– environmentally friendly, not only material, but also of the technological process,
– low heat conductivity (0,06–0,08 W/MK),
– low density (160-500 kg/m3),
– high compressive strength (0.8 to 7.5 MPa),
– low water absorption < 7%,
– non-flammable and durable material.
Application:
placeholder for super-light insulating concrete (composites) for binders, hydraulic or air curing,
placeholder for very light structural heat–insulating concretes (composites) and single-layer enclosing structures based on them,
filler in cement slurries (composites) for the oil and gas industry,
– mixtures for floor leveling,
– mixtures of heat-insulating, plastering,
– filler for flame retardant termotronic,
placeholder for scope of glass sheets (analog to “Knauf”), including laminated for furniture products,
filler in composite roofing materials, molded products obtained by extrusion (deck Board, door panels, siding, door, window lintels,etc.)
– insulation of pipelines and gas pipelines.
