How did the air in the internal structure of the vacuum pneumatic ball valve cylinder come from? Suspended ceiling wall pneumatic butterfly valve is mainly used in ktv, bars, slow shaking bars, hotels, clubs, cinemas and other places
The sound insulation target of KTV sound insulation materials is to select high-quality and inexpensive KTV sound insulation materials and cooperate with professional technicians to complete the KTV sound insulation project through scientific and reasonable acoustic design of the sound insulation structure. After completion, relevant environmental protection departments carry out testing to successfully meet the national standard
At the same time, in order to ensure that the sound insulation effect of KTV can reach the expected goal, what are the KTV sound insulation materials? The sound insulation function of KTV sound insulation materials is not only to reduce noise, but also to control
