Performance Of Cement Foam Insulation Board Introduction To Xinhui Insulation System Materials

Cement foam insulation board refers to the insulation board made by foaming cement technology. Cement foam insulation board is also called foam concrete insulation board and inorganic fireproof insulation board. It is a lightweight bubble-shaped thermal insulation material made from ordinary Portland cement, fly ash, foaming agents, admixtures, etc. through compounding, mixing, foaming, cutting and other processes. Its outstanding feature is the concrete interior. form.

Raw materials for cement foam insulation board production

The main material is cement, which is foamed by adding hydrogen peroxide, hard calcium, fly ash and cement foaming agent. Foamed cement insulation board is currently the insulation material for wall insulation and wall insulation fireproof isolation belts. Its advantages are: low thermal conductivity, good thermal insulation effect, non-flammable, waterproof, strong bonding with the wall, high strength, no toxic radioactive substances, and environmentally friendly.

Cement, powdery hydraulic inorganic cementitious materials. Add water and stir to form a slurry, which can harden in the air or in water with better effect and can firmly bond sand, stone and other materials together.

Cement foam insulation board performance

Xinhui foam insulation board is a high-performance inorganic insulation material. It is a porous, lightweight, high-performance conventional grade board. It is made from a variety of inorganic gelling materials and additives such as modifiers and foaming agents through a stirring system. , curing system, cutting system and other equipment, it is an inorganic thermal insulation material with low thermal conductivity, good thermal insulation performance, high temperature resistance, aging resistance, and A1 class non-combustible. Cement foam insulation boards can be widely used in building exterior walls. Insulation system.

1. Green and environmentally friendly

Green and environmentally friendly, no irritation, no release of harmful gases; no mineral wool floating matter causes damage to human skin and respiratory tract; flue gas toxicity reaches safety level (AQ1), no harmful gases and waste emissions during production, construction, and installation, low Carbon emissions; repeated removal of insulation does not produce waste that pollutes the environment.

2. Fireproof and high temperature resistant

The fire resistance temperature of cement foam insulation board can reach more than 1000 degrees Celsius, the combustion performance is A1 level, it is a non-combustible material and has excellent fire safety performance.

3. High thermal insulation

The closed cell rate of cement foam insulation board is greater than 97%. The high closed cell ratio significantly reduces air convection heat transfer. The thermal conductivity of cement foam insulation board can reach as low as 0.045W/m*k, which is basically the same as that of polystyrene board. It is quite suitable and can meet the needs of building insulation.

4. Low water absorption rate

The cement foam insulation board has low water absorption, which ensures that the product will not become moldy in a humid environment, will not affect the insulation performance, and ensures the safety and durability of the product.

5. Lightweight and high strength

Cement foam insulation board solves the contradictory technical problems of low density and high strength of materials and achieves relative unity. The density is 180KG/cubic meter, and the compressive strength reaches more than 0.2MPa, which meets the strength requirements during transportation and engineering applications.

6. Long life and aging resistance

Generally, the service life of organic insulation board systems is 25 years. When the life is over, heavy buildings need to be re-insulated for the second or third time; the life of cement foam insulation boards can be more than 50 years, which can be synchronized with the life of the building. The building only needs to be re-insulated throughout its life. One-time insulation construction.

7.Good overheating integrity

After technological improvements, the fire resistance limit of the cement foam insulation board has reached more than 3 hours, and it always maintains good fire protection integrity. It will not pulverize after encountering fire and its integrity will be maintained well.

8. Freeze-thaw resistance

Cement foam insulation board is a new type of insulation material obtained by our company's R&D team after improving existing foam cement products. After 25 consecutive freeze-thaw experiments, the product quality loss rate is less than 5%, and the strength loss rate is less than 20%. This allows the board to maintain stable physical and chemical properties under complex weather changes.

9. Good sound insulation effect

The internal structure contains a large number of independent bubbles, the sound absorption capacity is 5-7 times that of ordinary concrete, and the sound insulation effect reaches 60db (140mm). It is a new type of foam cement sound-absorbing and sound-insulating material.

10. Get along well with the opposite sex

Cement foam insulation board is a cement-based porous material with the same quality as mortar and walls. The interface is excellent and can be pasted directly after simple cleaning. It has strong stickiness.
