The sound absorption performance of the light sound insulation board (wallboard) is characterized by measuring the sound absorption average values of the sound absorption material at six frequencies of 125Hz, 250Hz, 500Hz, 1000Hz, 2000Hz and 4000Hz by adopting an AWA6122 standing wave tube.
Durability: after the lightweight acoustical panels (wall panels) of the above examples and comparative examples were respectively immersed in water at room temperature for 7 days, the surface of the lightweight acoustical panel (wall panel) was observed for the presence of dusting and peeling.
Self-cleaning property: the comprehensive stain resistance of the lightweight acoustical panel (wallboard) of the above examples and comparative examples was tested according to the test method of stain resistance of GB/T9780-.
The air purification function: respectively weighing 50g of the light sound insulation boards (wall boards) of the above examples and comparative examples as samples to be tested (wherein, the samples to be tested in examples 1-3 and comparative example 1 contain a nano coating layer), respectively putting the samples to be tested into a micropore box and placing the sample to be tested in the central position of a closed experimental device, immediately closing a device door after adding 3.3 microliters of 30% formaldehyde liquid, opening a heating table, starting a fan for stirring, so that formaldehyde gas is uniformly distributed in the whole experimental device, simultaneously recording the concentration of the formaldehyde gas in the experimental device in real time by using a formaldehyde sensor, and calculating the formaldehyde removal rate (%) at the same time.
