PENOIZOL

We offer the equipment for the production of heat-keeping material - penoizol (porous polyfoam). This equipment ideally suits both for small business and large industrial enterprises. Using this equipment it is possible to produce not only penoizol but also other polyfoams made of different resins (unipor).

Penoizol (unipor) is a new generation of carbamid heat-keeping polyfoams.

What materials are they? What differs them from all the rest? First of all, they possess high heat-keeping quality (the factor of heat conductivity from 0,035 - 0,047), low density (8 - 25 kg/cubic metre), big resistibility to fire, stability action of microorganisms, availability, low price. The 5 cm thick penoizol (unipor) plate with hard outside facing is equal to 90 - 100 cm brick masonry according to its heat conductivity.

These materials differ greatly from their predecessor (mipor) as they possess improved physicomechanical, ecological and operational characteristics. Penoizol (unipor) is produced by non-pressed way and without any thermal processing from foam-forming solution which includes polymeric (carbamid-formaldehyde) resin, foamer, catalyst solidify (acid). It is possible to add different modifications to improve physicomechanical characteristics. As a raw material we use cheap non-deficient components produced in Russia.

Penoizol (unipor) may be produced on the construction-site what affords to exclude expensive transport expenses and the loss of materials when being transported. From this material it is possible to produce plates of the required thickness or to pour it into hollow profiles of three-layer limiting constructions where it is polymerized and then dries in usual conditions.

In the constructions filled with penoizol (unipor) even if there are cracks in the external wall the danger of moisture getting into premises is excluded. Even if there is a lot of moisture at the border of internal surface of an external wall and warming, penoizol (unipor) does not let the moisture get inside (in spite of the fact that it has a porous structure) what prevents from increase of moisture in the building and the condensation of moisture on internal walls of a building. It is stable to the action of the bulk of aggressive surroundings, organic solvents, fungi and microorganisms.

Primary hardening of penoizol (unipor) lasts 15-20 minutes after going out of foamed solution from foam-forming sleeve but the following hardening lasts during 3-4 hours. During this time the material becomes elastic. Final hardening and drying of penoizol (unipor) take 1,5-3 days depending on the temperature of the environment.

Thanks to these advantages a low cost of the construction (though the quality of heat-keeping is rather high) is achieved and the production period decreases 4 times.

It is particularly perspective to use penoizol (unipor) at construction of 1-2 storeyed buildings such as hangars, covered platforms, at warming warehouses, garages, summer residences, at current and capital overhaul of inhibited and industrial buildings and constructions, for example, for isolation of roofs, walls, overlapping of floors, in roofing and wall panel with wooden or metal framework and with limiting covering, in sound proofing partition, to isolate pipelines, industrial refrigerators etc.

On the basis of experimental data got at tests for aging and procession experience of identical polymeric materials in the civil construction, we may guarantee that the forecasted service period of penoizol (unipor) for vertical constructions of premises is 35 years as minimum (It cannot be said about mineral waddling for instance).

The lack of ability to development of a stable burning process at tests, individual burning after switching off the source lighting and to the formation of melting when being burnt witnesses lowered fire danger of penoizol (unipor).

The tests of penoizol for toxicity have shown that after the completion of the process of polymerization and the initial stage of drying of polyfoam the emission of free formaldehyde does not exceed the norm of maximum concentration limit.

Binding of formaldehyde (the reduction of emission of free formaldehyde) can be realized by putting dried penoizol (unipor) on the protecting surface made of liquid glass. At the same time it is a hydrokeeping covering which serves to prevent from the insertion of moisture into open pores.

Thus, the produced complex of work directed to create new non-polluting safe generation of formaldehyde polyfoam let us recommend it for realization not only on the territory not only of Russian Federation but also on the territory of the countries of the CIS as a material for thermal isolation in the form of an average layer of protecting designs in inhibited and industrial constructions.

On the physicomechanical parameters polyfoam satisfies the following requirements (see the table).
