What is the difference between silicon calcium board and sound-absorbing board?
Silicon calcium board is made of siliceous material, calcium material, reinforced fiber as the main raw material, through the pulp, into blank, steam curing, surface sanding and other processes made of lightweight sheet. Is a hard board, and gypsum board is about, there is no sound-absorbing function, mainly from the decorative effect. Sound-absorbing board ceiling, also known as mineral wool board, is made of mineral wool, mineral fiber, perlite, starch and other renewable green materials. Has a high sound absorption capacity, not only play a decorative role in the ceiling, but also a sound and heat insulation effect. The price of silicon calcium board is cheaper, the market common mineral wool board brand also Armstrong, the United States Luda brand, in the sound-absorbing board to do this one is better.
Silicon calcium board is a compact board, basically airtight. Relative to the sound-absorbing panels heavier and harder. Is a sealed plate. Mainly from the sound effects. That is to stop the sound on both sides of the space in the spread of space. Sound-absorbing board is porous multi-slit plate, basically ventilated. Most of the things can be directly through the plate to see the other side of the board thing. Mainly from the sound-absorbing effect, that is, to weaken a certain frequency in the board side of the amount of reflection. Very few sound-absorbing panels directly to do the partition, so the sound-absorbing panels are generally not used to deal with the sound problems on both sides of the board, only dealing with unilateral sound field.
