The superior performance and application of inorganic glass bead insulation board:

1. Fire and heat insulation

Foamed cement board is a grade A non-combustible inorganic thermal insulation material, which has good fire resistance. It can be baked at a high temperature of 1200 degrees for 3 hours and still maintain its integrity. When used in buildings, it can improve the fire resistance of buildings. Because of its closed cell ratio>95, it has good thermal insulation performance. Xinyang inorganic glass bead insulation board belongs to A1 class fireproof material, which has good fire resistance, and the refractoriness reaches above 1100℃, which fully meets the fire resistance requirements of external wall fireproof insulation board. Since the closed cell ratio of inorganic glass beads used in the inorganic glass bead insulation board is >95, the high closed cell ratio reduces convective heat transfer, which is a prerequisite for high thermal insulation. Therefore, the thermal conductivity of the external wall fireproof insulation board can reach 0.055W/m·k, which is basically the same as that of the polystyrene board, which can meet the needs of building thermal insulation.

2. Lightweight shock resistance

The product has a light bulk density, a dry volume, and a density of about 250kg/cubic. The board has passed 1.5 million anti-fatigue vibration tests conducted by the National Test Center. The produced inorganic glass bead insulation board: waterproof, non-corroding metal: the immersion performance is enhanced, the board will not deform, swell or fall off after immersion, and maintain the original strength. Non-corrosive to wood and steel, the water absorption rate of this product is 50g/(m2.h), which is only about 1/10 of similar products. Low water absorption is an important feature that distinguishes this product from general inorganic thermal insulation materials. The water absorption rate means that the product will not be damaged by freeze-thaw cycles, and the interior will not seep water due to the use of inorganic thermal insulation materials on the outer walls, which means that the building has a longer service life.

3. Sound insulation

Because it is formed by porous and numerous independent bubbles, the sound absorption effect is about 5 times higher than that of ordinary concrete, and the sound insulation coefficient is greater than 45dB. The inorganic glass bead insulation board has an average sound absorption coefficient of 0.763 after testing; after testing, it can withstand 30J±1J energy impact, the arc crater depth is less than or equal to 20mm, and there is no crack damage; the impact resistance is in line with TB/T3122-2005 "Acoustic Components of Railway Sound Barriers" Technical requirements and test methods" standard requirements.

4. Convenient construction and high work efficiency

The construction is convenient, the construction period is short, there is no need for sand, cement and other materials in the construction, the material stacking is simple, efficient, small in size, occupies less resources such as site equipment, and has no construction waste, and no plastering is required after the construction is completed. The traditional block wall requires 12 people and 60 minutes of construction, and the foamed cement board can be completed in 3 people and 60 minutes, saving labor costs. Inorganic glass bead insulation board is easy to use, can be sawed, planed, and carved: no pollution during production, processing, construction and installation, low labor intensity, and no harm to the operator;

5, compressive strength, strong adhesion

Special fibers are used in the foamed cement board, which increases the compressive strength of the foamed cement board. After the inspection by the national professional testing organization, the flexural failure load is more than 3 times the weight of the bearing capacity (the national standard is 1.5 times), and the compressive strength It is above 5/mpa (the national standard is 3.5/Mpa), and the hanging force is above 1500/N (the national standard is 1000/N). The inorganic glass bead insulation board produced by the Pearl Sand Processing Factory: the strength is relatively good, and it is not easy to be broken. Uniform, non-fragile in use and transport, and compliant with fire integrity.

6. Non-toxic and harmless, environmental protection and energy saving

Foamed cement board uses cement and fly ash as the main raw materials for production. It does not burn at high temperature and does not release toxic chlorine. It is a safe and environmentally friendly material, and as a waste product, it is supported by domestic industrial policies. Inorganic glass bead insulation board: non-toxic and harmless The raw material of the inorganic external wall fire insulation board will not burn at high temperature and will not release toxic gas, and it is a safe and environmentally friendly building material.

7. Long life

The current design life of buildings in my country is generally 50-100 years, and the life of foamed cement boards is more than 50 years, which is the same as that of buildings. The CITIC inorganic glass bead insulation board produced: long service life The service life of the inorganic foam external wall fireproof insulation board for external wall insulation is more than 70 years, which can keep pace with the service life of the building.

The inorganic glass bead insulation board produced is mainly used as a filling material in building fireproof thermal insulation wall panels, steel fireproof doors, and wooden fireproof doors; it is widely used in homes, hotels, office buildings, commercial shopping centers, floors with high requirements for fire sound insulation and heat insulation. Various interior decoration partitions for compartments, schools, laboratories, hospitals, railway stations, subways, airports, theaters, dance halls, entertainment cities, factories, activity rooms, etc. It has the functions of fire prevention, heat insulation, sound insulation, etc., convenient construction, beautiful and durable, safe and environmentally friendly
