Abstract
1. Шумопоглощающее покрытие воздуховодных каналов отопительно-вентиляционной системы пассажирского помещения (кабины водителя) автотранспортного средства, содержащее слой пористого звукопоглощающего материала, облицованного с внешней стороны защитным слоем звукопрозрачной газовлагонепроницаемой пленки или ткани, а с внутренней стороны снабженным монтажным адгезионным слоем, отличающееся тем, что структура слоя пористого звукопоглощающего материала перфорирована сквозными отверстиями диаметром dпер=(0,1…0,5)h, где h - толщина слоя пористого звукопоглощающего материала, располагаемыми с межцентровым шагом tпер=(0,5…2,0)h, при этом коэффициент перфорации kпер лежит в диапазоне , где Sпер - суммарная площадь проекции отверстий перфорации на плоскость поверхности шумопоглощающего покрытия, Sпов - площадь лицевой проекции поверхности шумопоглощающего покрытия. ! 2. Шумопоглощающее покрытие по п.1, отличающееся тем, что торцевые поверхности шумопоглощающего покрытия облицованы защитным слоем звукопрозрачной газовлагонепроницаемой пленки или ткани с использованием липкого или термоактивного адгезионного вещества. ! 3. Шумопоглощающее покрытие по п.1, отличающееся тем, что торцевые поверхности шумопоглощающего покрытия выполнены газовлагонепроницаемыми с использованием герметизированного слоя соответствующего полимерного вещества, нанесенного методом напыления. !4. Шумопоглощающее покрытие по п.1, отличающееся тем, что торцевые поверхности шумопоглощающего покрытия выполнены газовлагонепроницаемыми, оплавленными посредством осуществления технологической операции термического воздействия на структур� 1. A sound-absorbing coating of the air ducts of the heating and ventilation system of a passenger room (driver's cabin) of a motor vehicle, comprising a layer of porous sound-absorbing material, lined with a protective layer of a soundproof gas-impermeable film or fabric on the outside, and provided with a mounting adhesive layer on the inside, characterized in that the structure of the layer of porous sound-absorbing material is perforated through holes with a diameter dper = (0.1 ... 0.5) h, where h is the thickness of the pore layer of true sound-absorbing material with intercenter pitch tper = (0.5 ... 2.0) h, while the perforation coefficient kper lies in the range where Sper is the total projection area of the perforation holes on the surface plane of the noise-absorbing coating, Spin is the area of the front surface projection sound-absorbing coating. ! 2. The sound-absorbing coating according to claim 1, characterized in that the end surfaces of the sound-absorbing coating are lined with a protective layer of a soundproof gas-impermeable film or fabric using a sticky or thermoactive adhesive substance. ! 3. The sound-absorbing coating according to claim 1, characterized in that the end surfaces of the sound-absorbing coating are made gas-tight using a sealed layer of the corresponding polymer substance deposited by spraying. !four. The sound-absorbing coating according to claim 1, characterized in that the end surfaces of the sound-absorbing coating are gas-tight, fused by means of a technological operation of thermal action on the structure
