Roofing a sandwich panel with (MVU) a mineral-cotton heater (basalt)

Key parameters and characteristics roofing a sandwich panels with a mineral-cotton heater (basic, help)

Panels construction three-layer roofing (PKTM) with metal facings and a mineral-cotton heater are manufactured on the automated hi-tech line of the Italian firm "PU.MA".

The made length of panels: from 2000 mm to 13000 mm.

Assembly width of panels: 1000 mm.

Dimensional width of panels: 1062 mm.

Heater thickness: 60 mm, 80 mm, 100 mm, 120 mm, 150 mm, 175 mm, 200 mm and 225 mm.

Heater: a heat-insulating plate from mineral wool on the basis of rocks of basalt group on synthetic CJSC Plant Minplita (Russian Federation), binding with gidrofobiziruyushchy additives of the LINEROCK the Sandwich To brand of production, or a plate with similar physics and technology and mechanical characteristics ("Evroizol", "ISOVER", "ROCKWOOL", "PAROC OY AB" and others).

Heater density: 125-140 kg/m ³.

Coefficient of heat conductivity of a heater: no more than 0,044 W / mk at a temperature of 25 °C (298±5)K.

Strength of a heater at compression: not less than 100 kPa.

Water absorption of a heater at short-term and partial immersion: no more than 1,0 kg/m ².

Sorption humidity of a heater: no more than 1,0% on weight.

Contents in a heater of organic substances: no more than 4,5% on weight.

Combustibility of a heater: not combustible.

Facings of panels – the high-quality thin-sheet galvanized holodnokatany steel meeting standards of the state standard specification 14918-80 Interstate standard from 0,5 mm to 0,8 mm thick of production of the leading metallurgical companies of JSC MMK – Magnitogorsk Iron and Steel Works and PAO "Severstal" – Cherepovets iron and steel works.

Front facing: pro-thinned out with height of a profile (corrugation) of 38-39 mm.

Internal facing: pro-thinned out with height (depth) of a profile (corrugation) of 2 mm or flat.

Two-component polyurethane glue of Dau Izolan and Bayer firms is applied to pasting of facings with a heater, and also the covering is applied with epoxy enamel which is the best adhesive for glue structure at production of panels on hire.

Protective and decorative paint and varnish covering on facings of panels: Polyester enamel (Poliefir), Polyurethane enamel (Pural), Polivinilidenftoridnaya enamel (PVDF) and the Plastisol (PVC) at the choice of the customer. Coloring of facings is carried out by high-quality paints and varnishes of firms "Akzo Nobel" (Sweden), "Prime Top Industry" (Russia) and "Yarli" (Russia) on the automated line of coverings of the English firm "Redman" by a roll method on the Coil Coating technology (continuous coloring) and meets standards of the state standard specification 30246-94 Interstate standard. At production of panels the protective assembly film is applied on the painted surface. Service life of a protective and decorative paint and varnish covering in the conditions of the open industrial atmosphere of a temperate and frigid climate – not less than 15 years.

Color scale of a protective and decorative paint and varnish covering: according to the RAL catalog.

Options of a protective and decorative paint and varnish covering: without paint and varnish covering (galvanized facings of panels), with a unilateral paint and varnish covering (front or internal facings of panels), with a bilateral paint and varnish covering (front and internal facings of panels).

Standard colors of a protective and decorative paint and varnish covering: RAL1014 (ivory), RAL1015 (beige), RAL1018 (bright yellow), RAL3003 (ruby), RAL3005 (dark cherry), RAL3009 (bullfight), RAL5002 (ultramarines), RAL5005 (alarm-blue), RAL5015 (heavenly-blue), RAL5018 (a sea wave), RAL5024 (gray-blue), RAL6005 (a green moss), RAL6026 (green fell down), RAL6029 (green mint), RAL8017 (chocolate-brown), RAL9002 (gray-white), RAL9003 (white), RAL9006 (a silver metallic). Coloring in other colors according to the RAL catalog is possible.

Fire safety: the limit of fire resistance of designs from a sandwich panels with a heater from mineral wool conforms to requirements of the state standard specifications 30247.0-94 and GOST 30247.1-94 Interstate standards: PKTM-60 of mm, 80 mm and 100 mm – REI30, PKTM-120 of mm, 150 mm, 175 mm, 200 mm and 225 mm – REI60 (at the density of heater of 120 kg/m ³).

Sandwich panel with a heater from mineral wool can be used for construction of designs from extremely high – the 1st degree of fire resistance. According to the state standard specification 30403-96 Interstate standard, designs from wall a sandwich panels with a heater from mineral wool have a class of fire danger K0.

Roofing a sandwich panel with a mineral-cotton heater can be used in the range of temperatures from +80 °C to -50 °C, at relative humidity of air to 60%, in the I-VII areas on wind and snow loadings.

Roofing a sandwich panel are applied in various roofing designs at construction of all types of buildings and constructions, to cattle roofs with a tilt angle not less than 6 °, i.e. with a roof bias not less than 1:10.
