What are Class A fireproof materials?

Class A fireproof materials include:

WW inorganic active wall insulation materials, cement foam insulation boards, vitrified microbead insulation mortar, rock wool boards, glass wool boards , foam ceramics, etc.

Common types of fireproof materials:

1. Fireproof board

Fireproof board is the most commonly used on the market. Material. There are two commonly used types: one is high-pressure decorative refractory board, which has the advantages of fireproof, moisture-proof, wear-resistant, oil-resistant, easy to clean, and has many designs and colors

; the other is glass magnesium fireproof board, The outer layer is decorative material, and the inner layer is mineral glass magnesium fireproof material, which can withstand high temperatures of 1500 degrees, but is not very decorative. Installing fireproof suspended ceilings in building exit passages, stairwells and corridors can ensure safe evacuation of people in the event of a fire and protect people from the spread of fire.

2. Fire doors

Fire doors are divided into wooden fire doors, steel fire doors and stainless steel fire doors. Fire doors are usually used in firewall openings, stairwell entrances and exits, evacuation walkways, pipe well openings, etc. They play an important role in fire separation and reducing fire losses.

3. Fireproof wooden window frames

Fireproof wooden window frames are surrounded by wooden sealing materials that expand when exposed to heat, preventing flames from penetrating through gaps. Even if the fire outside is fierce, It is also fire resistant for 30 minutes. This kind of window frame is made of pine wood, and a sealing material made of graphite is pasted around it to block small gaps and increase the fireproof effect.

According to experiments, a flamethrower was pointed at the window frame 10 cm away from the window frame, and a flame with a temperature as high as 800°C was sprayed out. After 20 minutes, the flame failed to penetrate the window frame, indicating that Its fire protection effect is several times that of aluminum window frames.

4. Fireproof roller shutters

Fireproof roller shutters can be installed in locations where it is inconvenient to install a firewall in the building. Fireproof roller shutters generally have good fire protection, heat insulation, smoke isolation, and resistance to fire. pressure, anti-aging, abrasion resistance and other functions.

5. Fire-proof and moth-proof wood

Fire-proof and moth-proof wood is to soak ordinary wood in a solution containing cations such as calcium and aluminum, and then put it into a solution containing phosphate and Soaked in a solution of silicate and other anions. In this way, the two ions will undergo a chemical reaction in the wood to form a ceramic-like substance, which will tightly fill the gaps in the cell tissue, thus making the wood fireproof and mothproof.
