Talking about the Effect of Flame Retardant in Air-conditioning Duct

Traditional air-conditioning ducts are prone to breeding of various bacteria, fungi and other microorganisms, and will be sent into the room with the air supply, affecting human health. The improvement of indoor air quality has become the development direction of modern air conditioning. Therefore, the addition of antibacterial agents to the paint can inhibit the growth of microorganisms in the air duct. The selected antibacterial agent is pyrithione, which has strong killing power against fungi and viruses.

The air circulation in air-conditioned rooms is poor, and there are few exchanges of fresh air with the outside world. After people work and live in them for a period of time, the indoor air will produce various odor molecules and the air quality will decline. In order to improve the quality of the air in the air-conditioned room, a deodorizing agent is applied to the inner surface of the air-conditioning duct to provide a deodorizing effect.

The mechanism for selecting chemical deodorization is to use photoreceptor media to react odor molecules to produce non-odorous molecules to eliminate odors. The main reagents for deodorant: aluminum acetate, photocatalyst, ping-pong, acetic acid, formaldehyde.

Flame Retardancy of Coatings In the copolymerization synthesis reaction of acrylate monomers, a synergistic component is added to match the brominated bisphenol ether flame retardant to achieve the flame retardant effect.

In the air duct of the new air conditioner, the glass fiber aluminum foil composite material is formed by bonding the glass fiber board and the aluminum foil layer aluminum foil glass fiber long screen mesh by cementing. Bonded glass fiber aluminum foil composite material can effectively prevent the generation and expansion of tensile cracks. Tensile fracture studies of glass fiber aluminum foil composite materials show that when the crack tip penetrates the edge of the slab, the glued part generates and expands due to fracture. With resistance, the fracture growth rate of the composite plate is rapidly reduced, and the composite structure is not easily destroyed, making it more superior in performance.
