Depth analysis of the sound insulation of soundproof doors:
The soundproof door is mainly used for sound insulation in high sound insulation requirements. The door leaf is mainly made of new galvanized steel plate, professional soundproofing material, damped acoustic board and soundproof cotton for soundproofing. At the same time, the most important soundproof door is Sealed treatment. The use of a magnetically controlled seal ensures a good seal sound insulation.
It has the following features: multi-layer composite, special sound insulation structure, and can withstand high temperature and pneumatic load. The soundproof door is divided into single door and double door, and the sound insulation effect of the single door is obviously better than that of the double door. With observation window, reliable sealing and flexible opening. The professional soundproof door production will not adopt the push-pull structure, and the push-pull type is not conducive to the sealing treatment, which will greatly affect the overall effect of the sound insulation.
The door needs to be opened so that its sound insulation performance is very different from that of the wall. The soundproof door not only depends on the performance of the soundproof door, but also is seriously affected by the gap between the fan and the frame. The upper limit of the amount of soundproof door is the sound insulation of the door leaf. This amount becomes smaller as the gap between the frame fans increases, especially in the middle and high frequency bands.
Ordinary building doors are mainly considered to be light, flexible, economical and other factors. There is no special sound insulation treatment, and the sound insulation performance is very low. Wooden doors are commonly made of wood, wood plywood, and fiber density boards. The weight of the door leaf is light, the gap between the doors is large, and the sound insulation is poor, generally around 15-20dB.
The steel door is made of angle steel, the steel plate is used as the surface layer, and the weight is larger. The door joint is sealed with sealing strips for consideration. The sound insulation is better than the wooden door, often around 20-25dB. There is also a plastic (plastic steel door), the door frame is plastic steel type, the door leaf is made of plastic plate, the weight is very light, the hardware seal is poor, and the sound insulation is generally not more than 15dB. In the high noise sound insulation, it is necessary to use the sound insulation door to improve the sound insulation performance of the door. On the one hand, it is necessary to increase the sound insulation of the door leaf, and on the other hand, it is necessary to handle the door gap.
Ways to improve the sound insulation of the door leaf itself are:
1) Increase the weight and thickness of the door leaf. But the weight can't be too big, otherwise it is difficult to open, the frame support is also a problem; too thick is not good, not only affects the opening, but also is limited by the lock. The weight of the conventional building acoustic door is less than 50kg/m2 and the thickness is not more than 8cm.
2) Using materials of different densities, such as multi-layer steel sheets and MDF composites, the thickness of each layer is also different to prevent resonance and anastomosis.
3) Form an empty stomach in the door leaf and fill the sound-absorbing material. The sound insulation of the door of the sound insulation door can be 50-55dB. The methods of door seam processing are:
4) Make the door frame into multiple tongues and seal with a sealing strip or sealing sponge. When using the sealing strip, it is necessary to ensure uniform pressure throughout the door joint and the pressure is pressed everywhere. Sometimes two sealing strips are used, but the processing precision of the door leaf and the door frame must be ensured, and the fit is good. Otherwise, the partial leaking seam is reversed and it is self-defeating.
5) Use mechanical pressing devices such as beading. A pressing device is installed around the door, and when the door is rotated, the pressing device is pressed against the door frame by mechanical linkage to obtain a good sealing property. For the diaphragm door without a threshold at the bottom, the mechanical seal must be installed at the bottom of the door. When the door is closed, the bead is automatically pressed against the ground to seal. The sound insulation of a single diaphragm door treated with a good door seam can reach 45-50dB.
