The basis of the technological process of production of thermal insulation materials ISOROC a product obtained by melting in a furnace-type basaltic natural minerals in the form of thin fibers formed in a uniform "carpet" with the addition of synthetic resin heat treated in a curing chamber, where it receives final product. This is followed by cutting of the product depending on the type and its packaging.
1. Selection of raw material components and their production preparation.
Selection of raw material components takes into consideration functional properties of mineral wool. The base material is basalt-type minerals and its equivalents.
2. Melting of mineral material
It takes place in a furnace at ~1500 degrees Celsius, where they melt to proper viscosity of lava.
3. Fibre creation
Lava goes to a centrifuge, whose main units are multiroller centrifuges, then to fibre formation chamber. While lava goes to rollers rotating 7000 rpm, the fibre starts to form and it is moved with a stream of air to a chamber, where so-called carpet is created.
4. Polymerization of resin
The “carpet” is moved to thermal processing chamber, where other physical and mechanical changes take place in the process of polymerization.
5. Cutting the carpet to proper dimensions.
Special machines designed to guarantee high quality precision cut the carpet into slabs.
6. Packaging ready products.
After cutting the product is packed in shrinking foil which guarantees protection while stored or transported.
Using contemporary scientific knowledge and technology, ISOROC produces new, highly effective thermal insulation ISOROC-type, designed to apply in residential or industrial buildings and etc. Using them allows to decrease costs of warming-up of buildings, thus living conditions make more comfortable. They also help to solve the problem of acoustic insulation (sound-absorbent quality), increase floor area, fire resistance and decrease foundation load.
High requirements of thermo-technical effectiveness, exploitational reliability and construction durability protecting buildings nowadays, directly influence upon physical and technical properties of effective insulation.
Basic exploitational factors are:
- temperature and humidity changes of thermal insulation constructions,
- possibility of capillary and diffusional moistness of thermal insulation products,
- load influence through the wind force,
- mechanical load through its weight in walls construction and caused by people movement on roofs construction.
Taking the factors into consideration, insulation materials should fulfil basic requirements:
- accounting coefficient of the thermal penetrability in exploitation - 0,04-0,06 Wt / (mK),
- absorbability should exclude damp absorption,
- frost resistance,
- density of thermal insulation products should not exceed 200 - 250 kg / m3, which is characterized
through maximum load,
- endurance coefficient with 10% deformation in insulated roofs construction not less than 0,020 MPa,
- breaking rings endurance coefficient in insulated constructions with plaster facades with strengthening of thermal insulation layer should not be less than 0,015 MPa,
- water resistance pH not more than 4,
- biological resistance and lack of toxic fumes during exploitation.
