What are the specific performance characteristics of foamed cement insulation board?

Cement foamed insulation board equipment takes industrial waste (fly ash) as the main raw material, and adopts patented foaming technology to produce foamed cement insulation board, which is suitable for making external wall insulation and fire-proof isolation belt and roof insulation material. Guangzhou Oufu builds domestic advanced technology, practical equipment and affordable cement foam insulation board production equipment.

I. Performance parameters of cement foamed insulation board products:

1, density: 130-280kg/m3.

2. Bending strength:/

3. compressive strength: > 0.5- 1.2mpa.

4. Thermal conductivity: 0.039-0.046

5. Water content: < 3%

6. Wet expansion rate: < 3%

7. fire resistance: nonflammable A 1.

8. Combustible temperature: nonflammable.

9. Sound absorption coefficient: 50 dB

10: surface flatness: 0.5mm.

1 1, thickness deviation: 0.5mm.

Second, the benefits of cement foam insulation board used in roof and wall insulation engineering

1, good thermal insulation: the thermal conductivity is 0.046-0.065 w/(m2k), and the thermal resistance is about 20-30 times that of ordinary concrete.

2. Good sound insulation effect: foam concrete contains a large number of independent bubbles, which are evenly distributed, and its sound absorption capacity is 0.09-0. 19%, which is five times that of ordinary concrete, and it has effective sound insulation function.

3. Good integrity: the site pouring construction is closely combined with the main project, and there is no need to leave boundary joints and ventilation pipes.

4. Low density: the dry bulk density is 180-260 kg/m3, which is the density of ordinary concrete 1/5- 1/8, which can reduce the overall load of the building.

5. High compressive strength: the compressive strength is 0.52-3.5Mpa.

6. Good waterproof performance: independent and dense bubbles and good integrity make it waterproof.

7. Crack resistance: the shrinkage rate is low, and the crack resistance is 8 times that of ordinary concrete.

8. Long life: 50 to 80 years, the same as the life of the main building.

9. Simple construction, good economy: simple and fast construction, consistent service life with the wall, and superior cost performance. During construction, there is no need to add any materials, just add water and stir it evenly, and directly put it on the wall to achieve the effects of smoothing, whitening, heat preservation, heat insulation and energy saving at one time. 20 yuan can be saved per square meter, and the comprehensive cost can be reduced 10%-30%.
