A, resistive sound insulation screen
Resistive soundproof panel Backplane side panels form a closed box structure, forming a modular unit. The panel is galvanized sheet with a perforation rate of 25%, the back plate and side plate are galvanized sheet without perforation, (for aesthetic consideration, color steel plate can also be used) the centrifugal glass wool filled between the two layers is moisture-proof and noise-reducing, and the sound absorption material is covered with polyfluoroethylene film. The columns are H-shaped steel, and the column spacing is 2m. The column is inserted into the reinforced concrete foundation, and is fixed, installed, maintained and replaced by fasteners between standard h-beams.
Two, ordinary transparent sound insulation screen
Ordinary transparent sound insulation screen uses transparent polycarbonate board (also known as PC board), because it is transparent, sound insulation barrier sense is better, easier to blend into the surrounding environment, color optional.
Three, microporous transparent sound insulation screen
Microporous sound insulation screen has 2 layers, it should be the principle of microporous sound absorption, in 1 layer of polycarbonate board through many holes with a diameter of 0.8mm, the perforation rate is 1%. Another layer of polycarbonate plate is not perforated,; The spacing between the two layers is 100mm, which is equivalent to a single-layer microporous sacrificial structure, which solves the contradiction between sound absorption and transparency. Thanks to sound waves, the pores don't get clogged with dust.
Four, compound sound insulation screen
Compound type separates sound barrier both transparent and opaque sound insulation screen have a bit. Half of him is a resistive sound insulation screen, the other half is transparent sound insulation screen, composed of one and two complex and the height of the above 4 sound insulation barrier can be combined freely according to the design requirements, can also be customized according to the requirements of the customer sound insulation screen.
