Problems solved by technology

Generally, when preparing flame-retardant insulating materials, flame retardants are added to improve the flame-retardant properties of insulating materials. However, most of the flame retardants contain halogens. When a fire occurs, the halogen-containing flame retardants will produce harmful gases after burning, which will poison the inhaler. , seriously affecting fire escape
