  • Detail

The sound-absorbing ceiling gypsum board composite sound-absorbing board is the bottom sound-absorbing cotton board, and the panel is "light perforated sound-absorbing panel". Perforated panels cannot be perforated calcium silicate board or perforated gypsum board

first stick a layer of afc-10mm damping pad and a layer of 3mm sound insulation felt on the original wall, make light steel keel, fill the keel cavity with a layer of afc-35 sound insulation cotton or a layer of afc-40kg sound insulation cotton, and then seal the afc-488 sound insulation board. Then afc-9.5mm perforated gypsum sound-absorbing board is used as exterior decoration to achieve the effect of "external sound insulation and internal sound absorption"

the base material of Huajiang ceiling, glass fiber, has strong thermal insulation property. The thermal insulation capacity of 3cm thick glass fiber is equivalent to that of 1m thick brick wall. After testing, the air conditioning power consumption of rooms with Huajiang ceilings is only about two-thirds of that of rooms with general ceiling materials

the glass fiber of Huajiang ceiling, as the base material, is an inorganic material and does not absorb water. At the same time, all of them are waterproof, and will not absorb water or moisture due to pores, nor will they condense. In other words, the ceiling can definitely be installed in places that are extremely humid and have no cooling and heating air-conditioning systems, such as swimming pools, kitchens, bathrooms and other humid places

1. The facilities and pipelines to be insulated shall be free of any leakage, and the surface shall be dry, free of grease and rust. In order to prevent corrosion, appropriate coating can be adopted

2. In order to achieve the small intention of heat loss Zui, all joints of plate and felt must be closely connected. During multi-layer insulation, the cross joints are probably intertwined to avoid forming a thermal bridge, and the cold bridge must be completely eliminated during cold insulation

3. Rock wool products are used for outdoor insulation or metal or plastic wrapping should be used in places prone to mechanical wear, and pay attention to the joints. If necessary, add colloidal seals, and the stacking of wrapping layers should not be less than 100mm

4. For cold insulation, it is necessary to add a moisture-proof layer on the ice face. When the temperature is extremely low, use rock wool without resin for insulation, and its moisture-proof layer should also be fireproof. Construction process of sound-absorbing board wall: 1 Adopt light steel keel or wood keel, fix the paper gypsum board on the keel with screws as the base plate, and scrape the gap of the gypsum board with putty

how to pierce the white perforated gypsum board

how to pierce the ceiling with perforated gypsum sound-absorbing board construction method: first, stick a layer of afc-10mm vibration damping pad and a layer of 3mm sound insulation felt on the original ceiling, and use elastic hooks for hanging reinforcement to deal with it and hit the light steel keel, Fill the keel cavity with a layer of ac-35 sound insulation cotton or a layer of afc-40kg sound insulation cotton, and then seal the ac-488 sound insulation board
