Identify the Flame Retardant Effect of Polyester Fiber Acoustic Panel

Identify the flame retardant effect of Polyester Fiber Acoustic Panel
(1) The flame retardant polyester fiber sound-absorbing board is harder and heavier than the general polyester fiber sound-absorbing board. The weight of the board with poor flame retardant performance is no different from that of the board that has not been generally treated.
(2) Polyester fiber sound-absorbing panels have high density. The density of the preferred polyester fiber sound-absorbing board must be high, that is to say, the board must be hard. Compared with some cheap boards on the market, this kind of polyester board has a price and a price. The polyester board of this material is not only the color Pure, easy to fall, no fuzz, very textured, and a lot of high-end.
(3) Processing technology of flame retardant polyester fiber sound-absorbing panels. There are many processes for flame retardant treatment of polyester fiber sound-absorbing panels. Different processes have different flame retardant effects. In order to improve production efficiency and reduce costs, many manufacturers directly spray a layer of solvent on the surface of polyester panels. The fire retardant of low degree, the fire retardant can not penetrate into the inside, and it is not uniform. As long as the corner of the board is separated, the ignition can also burn. In addition, after a long time, the fire retardant on the surface will volatilize, and the fire resistance will naturally decrease. .
