The manufacturer of foam aluminum sound barrier will tell you about the processing technology of metal sound barrier

Processing technology of metal sound barrier for foam aluminum sound barrier manufacturers

The processing of metal sound barriers is not as simple as photos, but also has its own manufacturing process and technical research methods. The processing process of metal sound barriers is complex, and each part has different process flows:

1、 Front panel technology of foam aluminum sound barrier

After material testing and entry, an appearance quality certificate is required and can only be obtained after passing the retest. Foam aluminum sound barrier

Considering the deviation and design changes of bolts, as well as the structural components with sound barriers, the relevant data will be inputted into the microcomputer of the front panel production line to accurately control the processing time and quantity of processed products of the front panel. The distance measurement work dimensions on site during construction, after the installation of h steel columns in sections a, b, and c will be analyzed and recorded, and numbered and organized separately.

2、 Processing technology of foam aluminum sound barrier rear panel

The computer of the rear panel production line in the measurement data input area accurately controls the length and quantity of the processed panels. The rear panel is fed, and the hot dip galvanized coils that pass the retest are installed on the uncoiler. The production line of the back panel enterprise is started, and the hot dip galvanized coils are fed into one production line; The hot-dip galvanizing roller entering the production line is automatically controlled by a computer to press the length of the galvanized sheet with a flat roller. After punching, the galvanized sheet is automatically rolled and formed into a waveform on the production line according to the requirements of design development; Professional injection molding is selected for injection molding. Before pretreatment, phosphorus and other spray, compared with the thickness of plastic layer above 76um, the plastic powder needs to be a practical pure polyester material. Check the spray, and conduct spray treatment on the protective film and conveyor layer pasted on the back panel to avoid damage; Check the length according to the design requirements of the back panel, width, surface roughness, and scratches to meet the listed quantity requirements.

3、 Packaging of foam aluminum sound barrier

The sound-absorbing cotton and alkali free water repellent glass cloth of the materials shall be designed and cut, and the materials shall be put into use, and then the materials shall be enveloped. After one of them is qualified after inspection, it can be numbered, classified, graded and sequenced, and marked with induction marks. The sound-absorbing cotton shall be superfine centrifugal Glass wool, with a weight of 48kg/m3 and a NRC of more than 0.95, according to the system data measured at the construction site.

4、 Assembly of sound-absorbing panel

Install the rear lower side and rivets on the assembled frame placed on the rear panel, add sound absorption, place the packaged sound absorption cotton according to the number, install the front panel, use the number to install the front panel, fasten and fix with rivets, install two side panels, and fix with rivets.

The inspection is to allow the inspector to check the length of the sound-absorbing panel, the width, quantity, and surface of the wound. After passing the inspection, the sound-absorbing panel code is arranged neatly and packaged uniformly using a dedicated wooden tray according to the number.
