SECCO sound insulation door It is designed according to the principle that sound waves will reflect when encountering the interface where the acoustic impedance changes in the transmission process, and multiple reflections will occur when the sound waves pass through the group resistance and pressure resistance of various materials. Its sound insulation ability is strong and its strength is high. In order to prevent the vibration of the sound insulation panel, special anti vibration treatment is adopted, which greatly improves the sound insulation effect, It is applicable to control the high temperature, high pressure, high noise test room and exhaust of high noise industrial plants and auxiliary buildings The Conduit Various types of operation rooms.
Scope of application
1.1 Sound insulation doors are applicable to industrial plants and auxiliary buildings with high noise (ventilator room, refrigerator room air conditioner Machine room, diesel alternator Room, printing workshop, etc.).
1.2 Sound insulation doors are applicable to halls with high requirements for acoustic environment (auditorium, conference hall, lecture hall, cinema, gymnasium, studio, recording room, studio, etc.).
1.3 The size of the sound insulation door opening is 900~3300 wide and 2100~3600 high.
1.4 Sound insulation amount of sound insulation door: when no threshold is adopted, its sound insulation amount is ≤ 30dB; When threshold method is adopted, its sound insulation is ≤ 40dB.
1.5 Steel fireproof and soundproof doors are applicable to places with both sound insulation requirements and fire protection requirements.
2 Material of SECCO soundproof door leaf
2.1 The filler materials and thickness in the sound insulation door leaf shall be determined by the manufacturer according to the sound insulation amount and fire protection requirements. For filling in general door leaf Glass The volume density of cloth wrapped medium grade glass wool fiber or rock wool products shall be controlled within 80~100Kg/m ³.
2.2 The frame and panel materials of sound insulation door leaf can be divided into six types:
Type a is profile steel skeleton and cold-rolled steel plate panel (without door frame);
Type b is profile steel framework and cold-rolled steel plate panel (without door frame);
Type C is light steel keel framework and color steel plate panel;
Type d is light steel keel framework and cold-rolled steel plate panel;
Type e is light steel keel framework and galvanized steel plate panel;
F type is wood skeleton and leather upholstered panel;
2.3 Type e is a fire and sound insulation door. The designer shall indicate the fire rating of the door and the requirements for the exterior materials of the door leaf when selecting the door in the project design.
2.4 When using the sound insulation door selection table, the designer shall add the material type code according to the design requirements.
2.5 SECCO sealing strip: EPDM rubber products are used.
It is applicable to industrial plants and auxiliary buildings with high noise (ventilation room, refrigeration room, air conditioning room, diesel generator room, printing workshop, etc.) and places with sound insulation requirements for civil buildings with equivalent conditions of cultural and entertainment buildings (such as auditorium, conference hall, lecture hall, cinema, gymnasium, studio, recording room, studio, etc.). For the occasions where the door needs to be harmonious and unified with the surrounding environment, and the decoration requirements are high, the surface of the door body can be subject to secondary decoration.
The size of the door opening is 900~3300 wide and 2100~3600 high.
The overall dimensions and opening mode of the door body are customized according to customer requirements.
Sound insulation: when no threshold is adopted, the sound insulation is ≤ 30dB; When threshold method is adopted, its sound insulation is ≤ 40dB.
Steel fireproof and soundproof doors are applicable to places with sound insulation requirements and fire protection requirements.
