One, sound insulation ceiling material
1, light steel keel gypsum board
Light steel keel gypsum board is made of gypsum board and light steel keel joint into a suspended ceiling material. Gypsum board is with plaster of Paris as the main raw material, mixed with additives and fiber production and become, the quality of a material is light, with good heat insulation, sound absorption, flame retardant and other properties. From the use of the situation, the current use of light steel keel gypsum board as a partition wall in the majority, less used in the ceiling ceiling.
2. Mineral wool ceiling
Mineral wool ceiling is made of mineral wool as the main material, mineral wool is slag (waste slag) and organic matter after melting through high temperature, and then through the high-speed centrifuge thrown out of the flocculent. The biggest advantage of mineral wool ceiling is to reduce the noise, sound insulation effect is very good. When indoor sound waves reach the mineral wool ceiling, they will be absorbed by the material, which can effectively isolate the noise and help to create a relatively quiet indoor environment.
3. Aluminum honeycomb perforated sound absorbing board
Aluminum honeycomb perforated sound-absorbing board is composed of perforated panel and perforated back board. It adopts high quality adhesive to directly bond with aluminum honeycomb to form aluminum honeycomb sandwich structure. A layer of sound-absorbing cloth is pasted between the honeycomb core and the front panel and the back board. The aluminum honeycomb perforated sound-absorbing board has large surface and high strength, but the material is light, especially the sound-absorbing effect is very good.
4, plywood,
Plywood, also known as plywood, is made by cooking and softening logs, cutting them into large sheets along the rings, and drying, finishing, gluing, forming, hot pressing, and sawing. Plywood material is lighter, higher strength, with good toughness, impact and vibration resistance, and easy to process, can be coated. Suitable for small area ceiling.
Two, sound insulation ceiling how to do?
1. Prepare for suspended ceiling
Keel ready to complete, including derrick, side keel, load keel, face keel, cross support keel and so on, and ensure that the quality of keel installation reliable standards. The edges of the keel or joist must be properly cleaned and dried. Remove nails, screws or other obstacles that protrude from the keel or joist.
2. Draw a line on the ceiling to indicate the keel
Measure the working space, draw a line on the ceiling with infrared ray measuring instrument, indicate the position of ceiling shock absorber and keel, and adjust the levelness of the ceiling. Before installing soundproof board, should install smallpox first on existing condole top shock absorber, not only can reduce the rigid connection of sound insulation condole top and original ceiling.
3. Install ceiling shock absorber, keel and accessories
According to the location of the ceiling, install ceiling shock absorber and screw rod, screw rod length according to the height of the ceiling to determine, at the same time install the ceiling pendant and fastener, fixed ceiling keel, adjust the ceiling level.
4. Measure and cut
Measure the working space and, if necessary, cut the soundproof panel to the appropriate size to minimize the gap between the soundproof panels or between the soundproof panel and other existing surfaces.
Soundproof panels can be cut from either side by cutting or sawing. When cutting with a knife, use a standard tool knife or similar tool to cut a deep scratch on one side of the wallboard, and then cut a scratch on the other side that is aligned with the scratch above, so that the soundproof board can be broken. To keep the seams clean, compact and parallel, we recommend cutting with a chainsaw and should smooth the edges and ends.
Installation of sound insulation board long side long side should be perpendicular to the direction of the sub keel, short side staggered joint installation.
5. Seal, secure and cotton
Using a caulking gun on an existing wall, floor or floor slab, apply a sound sealant about 5mm wide to the place where the outer edge of the soundproof board will be placed. Place soundproof board, after fixing, daub sealant around it, repeat on the step of resistance, will soundproof board is full of metope. When placing soundproof board, make sure as far as possible between soundproof board, soundproof board and wall, floor, smallpox between close contact. The sound-absorbing cotton is placed on the board while the sound insulation board is installed.
For securing the soundproof panels, use the diameter and length of the wall plate screws of the local building code, usually no. 8 horn head fine thread screws (for metal keels). These screws should be screwed into the position flush with the surface of the sound insulation board, and should not crack the surface of the sound insulation board. What should be noted is that the sound insulation board should be fixed on the keel with the screw spacing of 100mm in the periphery and 150mm in the middle. Sound insulation board should be with the keel or joist edge close together, sound insulation board joints should be staggered.
6. Seal the hollowed frame and perforating hole
Due to the air and building as the transmission carrier of sound has a strong permeability, therefore, when in order to take care of the sky lanterns hole, pipe, ceiling fan, etc. in the wall panel frame or hole, with sound insulation sealant sound insulation wall board with hollow-out frame or hole between the gap between the hole for sealing.
7. Seam treatment and modification
Tape the seams as you would normally do with plasterboard. On the surface of the sound insulation board to play putty, paint, paint, paste wall cloth and other modifications.
In a nutshell, acoustic ceiling still has certain scientific reason, we in the treatment of the condole top, might as well use this way, and the ceiling is decorated, in addition to sound insulation, ceiling and there are many problems, it is worth noting that the size we should accomplish know fairly well, to these questions can we decorated the satisfaction.
