Cette matière est similaire au bois naturel par ses propriétés, mais elle dépasse le bois par sa résistance au feu, à la chaleur et au gel. Par ailleurs, elle peut servir plus longtemps et coûte environ deux fois moins cher que le bois. Cette invention a reçu le nom de vinizol et suscite un grand intérêt de la part des compagnies russes et étrangères, spécialisées dans la construction des bâtiments de faible hauteur.

Project description
The technology of manufacturing of the new fireproof constructional building material was developed at the Mineral processing and
engineering ecology department (MPEE) of Irkutsk state technical university (ISTU). The proposed material is based on ash-and-slag (heat
electropower station wastes) and polymer waste products.
VINIZOL is close to the natural wood and excels it by some of its characteristics: heat resistance, frost resistance, chemical and biological
durability (rotting, molding), longevity. Porosity introduces new advantages to the developed material, such as ease, water resistance
and hydrophobic property.
The VINIZOL's manufacturing technique is extrusion.
It is planned to carry out the scientific research simultaneously with the manufacturing, that will allow to produce the diversified material's
range. It will be possible at the expense of using waste products and variation of the specific content of ash in the base mixture.
Due to the VINIZOL's water resistance and high durability it can be applied to: outboard walls, houses panelling, terraces, hortensial
furniture, decks, patio, outboard window and door frames, fences, roof tile, piers, pavements, vessel's deck.
VINIZOL can also be used indoors: floor, ceiling, doors, inner window and door frames, wall panels, furniture, veneer, plinth, etc.
The developed material is able to meet competition as it matches up-to-date fire and ecological safety demands. As VINIZOL is based
on cheap large-capacity waste products, its cost is much lower than the analogues' ones.
VINIZOL is machined by all the same tools as natural wood. The developed material is easily sawed, planed and perforated. It can also
be easily dyed. It holds up pins, cramps and screws. Some of the material's sorts can be cemented; some other ones can be welded in
common with the plastic.
