AI Technical Summary
Traditional firewalls are prone to absorbing dust and particulate pollutants in high-cleanliness environments, and cannot effectively filter smoke and dust, affecting aesthetics and fire resistance, and their structure is easily damaged.
It adopts a light steel keel structure, a perlite fire-resistant insulation board, rock wool filling and a nano-grade alumina-coated cleanroom board, combined with silver ion antibacterial agent to form a cavity structure, which enhances fire resistance and cleanliness.
It achieves improved fire resistance in high-cleanliness environments, enhanced structural stability, ease of cleaning, a fire resistance limit of up to 4 hours, reduces the spread of pollutants, and meets the requirements of high-cleanliness environments.

Abstract
Claims
1. A fire wall having good cleaning performance, comprising a transversely arranged ground bone and a top bone, characterized in that: A first light steel keel layer (1) and a second light steel keel layer (2) are vertically arranged between the ground bone and the top bone. A cenosphere fire-resistant insulation board (3) is arranged between the first light steel keel layer (1) and the second light steel keel layer (2). The first light steel keel layer (1) and the second light steel keel layer (2) form cavities with the cenosphere fire-resistant insulation board (3), and the cavities are filled with rock wool (4). A clean plate (5) is provided on the outer side of the first light steel keel layer (1) and the second light steel keel layer (2). The surface of the clean plate (5) is coated with a nano-level alumina coating, and silver ion antibacterial agent is added to the coating.
2. The fireproof wall with good cleaning performance according to claim 1, characterized in that: The first light steel keel layer (1) and the second light steel keel layer (2) each include several vertical main keels (11), and the main keels (11) of the first light steel keel layer (1) and the main keels (11) of the second light steel keel layer (2) are arranged in a staggered manner.
3. The fireproof wall with good cleaning performance according to claim 2, characterized in that: The first light steel keel layer (1) and the second light steel keel layer (2) are provided with a number of transverse secondary keels (6).
4. The fireproof wall with good cleaning performance according to claim 1, characterized in that: The lower ends of the cenosphere refractory insulation board (3) and the clean board (5) are provided with splicing grooves (7). The groove side of one side of the splicing groove (7) extends towards the opening of the splicing groove (7) to form an outer flange (8). The upper ends of the cenosphere refractory insulation board (3) and the clean board (5) are provided with splicing protrusions (9) that are compatible with the splicing groove (7) and the outer flange (8). The upper side of the clean board (5) is provided with a countersunk hole (10). The countersunk hole (10) can penetrate the outer flange (8) in the direction of extending towards the main keel (11).
5. The fireproof wall with good cleaning performance according to claim 1, characterized in that: The rock wool (4) is a hydrophobic rock wool with a density of 80-100 kg / m³ and a fiber diameter of 3-5 μm.
