The customer thinks that the sound-absorbing board is just punched out. Why is the price many times higher than that of the ordinary board?
The guest said: "For the 30-40 yuan rock wool board outside, why does your company's sound-absorbing board cost more than 90 yuan? It's nothing more than punching..."
The following editor specifically addresses this question from the customer:
1. The color steel sound-absorbing board is essentially not a rock wool board, but a high-density glass wool board. If rock wool is to be used, the density needs to reach 100KG/cubic meter.
2. The punching rate needs to be more than 20%, and the hole diameter is 2.5mm and 6.0mm. The sound absorption effect is different.
3. The color steel sound-absorbing board does not use ordinary AB compound glue, which has high requirements for glue and needs to be sprayed.
4. Color steel sound-absorbing panels need to use non-woven fabrics, which have strict requirements on the density and thickness of non-woven fabrics. The price of good non-woven fabrics is very different from ordinary prices.
5. Color steel sound-absorbing panels are not simply made out of ordinary rock wool machine-made panels. There are many manual processes in order to ensure the strength of the panels.
6. The steel plate used for punching needs to be more than 0.5mm, because it is too thin when rewinding, the steel plate is easy to be deformed when it is punched, and it is easy to bulge when it comes back.
7. The upper and lower punching steel plates of the color steel sound-absorbing panels have high requirements for paint, and the paint coating should not be too bad, it should be thick, or it is easy to burst.
The above is the reason why the sound-absorbing board is more expensive than the rock wool board. I hope it will be helpful to everyone!
