Performance of Cement Foamed Insulation Board
1, environmental protection
There is no harmful gas and waste discharge, and it will not pollute the environment.
2, fire and high temperature resistance
Fire resistance temperature 1000℃ or above, A 1 level.
3, high thermal insulation
The closed-cell ratio is more than 97%, and the lowest thermal conductivity is 0.045W/m*k, which meets the requirements of building thermal insulation.
4. Low water absorption
Low water absorption, no mildew, ensuring the safety and durability of products.
5. Light weight and high strength
The technical problems are solved and the relative unification is realized. Density 180kg/m3, compressive strength above 0.2MPa.
6, long life, anti-aging
The service life is more than 50 years, synchronized with the building, and only one insulation construction is needed for the whole life.
7, good fire integrity
The fire resistance limit exceeds 3 hours, and the integrity is good after the fire.
8. Freeze-thaw resistance
After 25 freeze-thaw tests, the mass loss rate is less than 5%, the strength loss rate is less than 20%, and the physical and chemical properties are stable.
9. Good sound insulation effect
The sound absorption capacity is 5-7 times that of ordinary concrete, and the sound insulation effect reaches 60db( 140mm).
10, good workability
Porous materials can be directly pasted, and the viscosity is firm.
1 1, low cost.
The cost of building insulation can be reduced by 3-5 times.
Cement Foamed Insulation Board-Product Features
Environmental protection and low-carbon new material, the fireproof performance reaches A 1 level, it is firmly bonded with concrete, the expansion coefficient is consistent, and the service life is consistent with that of buildings. Used for roof insulation board, internal and external wall insulation board.
Cement foam insulation board-raw materials for production
The most ideal thermal insulation material has the advantages of low thermal conductivity, good thermal insulation effect, incombustibility, waterproof, strong adhesion to the wall, high strength, non-toxicity and environmental protection.
Selection skills of cement foam insulation board
1, depending on the weight and strength. Only when the comprehensive effect of thickness/bulk density/compression ratio/binder passes the test can the plate pass the test.
2, look at the choice of binder. The selecte magnesium oxide has good activity, high price, exquisite manufacturing proces and good water resistance.
3. smell it. If there is a pungent smell, it does not meet the requirements of environmental protection.
