Claims (8)

1. Способ обработки куска отвержденного вспененного материала, имеющего верх, низ и боковые края, высота (толщина) которого измеряется как расстояние между его верхом и низом, который включает сжатие указанного куска со скоростью не более 3,65 м/мин (двенадцать футов в минуту), прекращение указанного сжатия, когда указанный кусок сжат до толщины, составляющей не более 15% от указанной, поддержание давления, приложенного к указанному куску, в течение периода времени не более одной минуты после прекращения сжатия указанного куска, сброс указанного давления, приложенного к указанному куску, и выдерживание указанного куска для восстановления в течение периода времени не менее 48 ч, причем происходит улучшение звукопоглощающих свойств указанного куска.1. A method of processing a piece of cured foam having a top, bottom and side edges, the height (thickness) of which is measured as the distance between its top and bottom, which involves compressing the specified piece at a speed of not more than 3.65 m / min (twelve feet in minute), the termination of the specified compression, when the specified piece is compressed to a thickness of not more than 15% of the specified, maintaining the pressure applied to the specified piece for a period of time not more than one minute after the termination of the compression of the specified piece, the discharge specified of pressure applied to said piece and maintaining said piece for recovery of at least 48 hours for a period of time, and there is improved sound absorption properties of said piece. 2. Способ по п.1, в котором указанное сжатие производится со скоростью не более примерно 1,52 м/мин (5 футов в минуту).2. The method according to claim 1, wherein said compression is performed at a speed of not more than about 1.52 m / min (5 feet per minute). 3. Способ по п.1, в котором указанный период времени составляет не менее 72 ч.3. The method according to claim 1, in which the specified period of time is at least 72 hours 4. Способ по п.1, в котором указанное давление, прикладываемое к указанному куску, находится в диапазоне значений 55-83 кПа (8-12 psi).4. The method according to claim 1, in which the specified pressure applied to the specified piece is in the range of values 55-83 kPa (8-12 psi). 5. Способ по п.1, в котором указанное давление прикладывается к верху указанного куска.5. The method according to claim 1, in which the specified pressure is applied to the top of the specified piece. 6. Способ по п.5, в котором указанное сжатие прикладывается по существу равномерно вдоль указанного верха указанного куска.6. The method according to claim 5, in which the specified compression is applied essentially uniformly along the specified top of the specified piece. 7. Способ по п.1, в котором указанный кусок сжимают до значения, составляющего не более 10% от указанной толщины.7. The method according to claim 1, in which the specified piece is compressed to a value of not more than 10% of the specified thickness. 8. Способ по п.1, в котором вспененный материал является полиимидом.8. The method according to claim 1, in which the foamed material is a polyimide.
