In the sales market, some sound-absorbing panels are made by installing a plastic layer, shock absorbing raw materials, or sound insulation blankets between two panels. Choosing this method can improve the actual sound insulation and noise reduction effect to a certain extent in the short term, but its actual sound absorption effect will gradually decrease over time. As we all know, raw materials such as plastic will gradually age in the air, causing them to gradually harden and lack ductility, thereby causing the actual effect of sound insulation and noise reduction to gradually decrease over time. On the other hand, the method of installing a plastic layer or soundproof blanket layer in the middle of two boards also has a particularly high engineering budget. Perforated calcium silicate board is a new material made of a composite layer of polymer material in the middle of two boards using a unique processing technology. The characteristics of this raw material will not change for a lifetime, and the actual effect of sound insulation and noise reduction will remain unchanged for more than 50 years. The Zhilv acoustic material sealant used to seal the gaps on the wall also maintains viscoelasticity for life, and is always not easy to crack or deform. The actual effect of sound insulation and noise reduction is ultimately not easy to reduce.
Installation method of perforated calcium silicate board
1. Carry out decoration ceiling construction and setting out, clarify the fixed and fixed parts of the screw rod, and the core distance of the screw rod is generally 1220mm.
2. Connect and fix the screw rod to the ceiling keel with a hanger, and keep the ceiling keel level.
3. Fix the secondary main keel vertically on the ceiling keel with small pendant, and the Centre-to-centre distance of the secondary keel axis is 612mm.
4. The main keel of the cross brace must be installed as required, and the center Centre-to-centre distance of the cross brace keel is 1224mm.
5. Fix the board with self tapping screws and fix it on the main keel of the flash, and solve the gaps properly.
3. Classification status of perforated calcium silicate boards:
1. Aluminium silicate fiber perforated calcium silicate board:
Perforated calcium silicate board made from chemical fibers such as asbestos as raw materials, with zero composition of asbestos in the product.
2. Perforated calcium silicate board with asbestos: Chrysotile perforated calcium silicate board
The chemical fiber reinforced perforated calcium silicate board is made of a single Chrysotile chemical fiber or mixed with other chemical fibers to improve the raw material. The product contains Chrysotile.
