Method, the acoustic material being prepared by this method, and the system of sound panel and sound panel that is prepared using the acoustic material
Preparation Method.
Background technology
Now, with the continuous acceleration of urbanization, noise pollution also becomes increasingly severe.It makes an uproar to effectively separate
Sound, common settling mode are to use acoustic material.Existing acoustic material is generally cement concrete, glass plate etc., these
The soundproof effect of acoustic material is not fine, therefore common solution is to increase the thickness of acoustic material, is caused in this way
The problem of be that acoustic material quality is overweight, cost is excessively high, and installation process is inconvenient.
Containing components such as a large amount of sulphur, lime in Industry Waste ash, giving up to this part, there are as below methods for grey processing --- and it is straight
Connect exhaust method, terminal processes method, cycling and reutilization method etc..Wherein, direct emission method, give up ash in untreated sulphur and lime etc.
It would seriously pollute the environment；Terminal processes method, needs to collect all useless ashes and focuses on again, and investment is big；And cycling and reutilization method is
One more effective processing method.
Iron-ore Slag is iron ore exploitation or the impurity that is detached after being produced using iron ore as raw material, mainization of Iron-ore Slag
Studying point has：Iron, iron oxide, silica and ferrous oxide etc. can recycle metal therein with high-temperature chlorination, reduce pollution
Object discharges.Iron-ore Slag stores up land occupation, builds stockyard and expends a large amount of human and material resources.Ground-slag is flown upward, and pollutes air and peripheral ring
Border.Iron-ore Slag quality is loose, and is porous shot-like particle, is suitable for making acoustic material.
Sound panel is a kind of plank acting on soundproof effect, and present sound panel majority is to install rubber between the two plates
What glue-line, damping material or deadening felt etc. were made, the material one side service life is short, and soundproof effect declines with service life,
On the other hand with high costs, bad practicality.
