Soundproof spraying room

According to the acoustic principle, the noise generated during spraying is controlled in the room to prevent the staff outside the room from being injured by noise pollution. After the establishment of the soundproof room, the noise emission in the operation area is lower than the "Noise Hygiene Standard for Industrial Enterprises" stipulated by the state.

The soundproof room is composed of four corner steel columns, wall panels, roofs, upper and lower grooves, corners, gap seals, etc., which not only ensures the sound insulation and overall rigidity of the room, but also pays special attention to the beauty of the appearance and thoughtful details.

L-shaped spraying soundproof room

The design of this spraying soundproof room project follows the following principles:

1. Strictly implement relevant national industry standards and general technical specifications;

2. The selected technologies are mature and reliable technologies, and have been successfully used, without any test components;

3. Design to meet the actual production process needs of customers;

4. Combined with our company's many years of professional experience and the structural characteristics of the workpiece itself, in line with the purpose of meeting the needs of users, the design and production focus on equipment stability, safety, environmental protection and energy saving;

5. People-oriented, fully from the perspective of the actual operation of operators and maintenance personnel, comprehensively consider the stability of equipment and the convenience of maintenance and maintenance.

Acoustic panels

The structure of the plate group is: the outer wall is 2.0mm thick white sprayed steel plate, the middle filling damping layer, the asbestos board, the double-layer 100Kg/m3 high-solubility heavy sound-absorbing cotton, waterproof and dustproof sound-permeable film, and the inner wall is a metal porous sound-absorbing board (punching rate of 25%). The sound insulation board is supported by the welded tic-tac-toe steel frame for strength, and then pressed into shape, and the sound insulation board is smooth and scraped inside and outside, and the surface is bright and beautiful.

The standard panel is 970mm wide and 140mm thick, and the length can be determined by the required height of the room. The sound insulation board has been tested by noise (the tested sample does not put gypsum board), and the air sound insulation in the sound frequency range of 125~4000Hz is 42dB (A). At present, the sound insulation of the sound insulation board after adding PDF glass fiber board is larger, and the sound insulation board is assembled by a special thickened steel plate, and the cement is plugged to prevent sound leakage in the gap;

Acoustic doors

We design the soundproof door for the workpiece to enter and exit with a stepped sealing structure, the sound goes through the stepped structure to achieve the purpose of noise reduction, and the door is sealed with a sealing strip, which plays a sealing role when the door is opened and closed, reducing the leakage of sound.

Soundproof windows

Observation windows are provided on the soundproof wall panels and soundproof doors, and the observation windows are made of transparent tempered glass, and the number of observation windows on the soundproof panels is specified by the owner. The specification of the observation window is: 700*1000 (H)mm, which is a two-channel double tempered glass structure; The specification of the observation window on the soundproof door is: 400*400 (H)mm, and its sound insulation is basically equivalent to that of the wallboard.

Intake and exhaust mufflers

In order to meet the needs of indoor dust extraction and air suction, the spraying room is equipped with air inlet muffler and exhaust muffler to keep the indoor negative pressure balanced. While the airflow passes through the muffler, the indoor noise is absorbed by the muffler. Prevent noise from spreading outward through the air intake.

2. Product Operation Guide

I. Pre-operation Preparation

1. Equipment & Structure Inspection

• Check for damage to the spraying booth structure (walls, doors, windows) and repair promptly if damaged.

• Inspect the connection and sealing of spraying equipment (spray guns, pipelines, pressure tanks), and confirm equipment parameters match the task requirements.

• Verify the operation, blockage, cleanliness, and noise-reduction performance of the ventilation system (fans, pipelines, filters, mufflers).

2. Environment Cleaning

• Clean dust and debris inside and outside the spraying booth.

• Keep surrounding passages unobstructed and avoid stacking miscellaneous items.

3. Coating & Auxiliary Preparation

• Select coatings based on workpiece requirements, check coating quality, and process as needed.

• Prepare auxiliary materials (e.g., diluents), mix in the correct proportion, operate in a well-ventilated area, and mark clearly.

4. Operator Protection

• Operators must wear protective work clothes, gas masks, gloves, and earplugs.

II. Spraying Operation Procedures

1. Workpiece Fixing

• Move the workpiece into the booth and secure it with a clamping device to prevent surface damage and ensure full coverage of all spraying surfaces.

2. Parameter Adjustment

• Adjust spraying equipment parameters (pressure, flow rate, spray gun-workpiece distance, angle) and ventilation system parameters (ventilation volume, operation time) according to coating and workpiece characteristics.

3. Formal Spraying

• Turn on the coating delivery system to circulate the coating.

• Hold the spray gun and spray along the preset route, maintaining stable gun movement speed and distance.

• Pay attention to the interval between multi-layer spraying, observe the spraying effect in real time, and adjust parameters promptly if needed.

III. Post-operation Handling

1. Equipment Shutdown

• After spraying, first turn off the coating delivery system to allow residual coating in the spray gun to flow back, then cut off the power supply.

• Shut down the ventilation system, close the booth door, and let harmful gases disperse naturally for a period.

2. Cleaning & Maintenance

• Disassemble and clean the spray gun and pipelines, using solvents to remove coating residues.

• Clean paint stains on the booth’s internal floor, walls, and clamping devices, dispose of waste properly, and check/replace ventilation system filters as required.

3. Workpiece Inspection & Curing

• Remove the workpiece and perform drying/curing according to coating requirements.

• Inspect the workpiece coating (appearance: flatness, bubbles, sagging, color; physical properties: adhesion, hardness).

4. Record Keeping

• Document the spraying date, time, workpiece/coating information, equipment parameters, encountered problems, and corresponding solutions.

Q: Can the ventilation system effectively exhaust paint mist and harmful gases? Will there be any residue?

A: The ventilation system we equipped is carefully designed. The fans are of high-power and large-air-volume models, the ventilation ducts are reasonably laid out, and high-efficiency filters are installed. Under normal operating conditions, it can exhaust paint mist and harmful gases, such as formaldehyde and benzene, in a timely and thorough manner, ensuring that the concentration of harmful gases in the booth is always kept below the safety standard without obvious residue, safeguarding the health and safety of operators.

Q: What standard specifications are available for selection? If my workpiece has special dimensions, can it be customized?

A: We have a professional design team that can customize the soundproof spraying booth according to the detailed dimensions of your workpiece and spraying process requirements to ensure a perfect fit for your production needs.

Q: Is the subsequent operation cost of using this soundproof spraying booth high?

A: The subsequent operation cost mainly includes aspects such as energy consumption and consumable replacement. In terms of energy consumption, the ventilation system and some temperature control devices are the main energy-consuming parts, but our products use energy-saving equipment, and the power consumption is within a reasonable range during normal operation. In terms of consumables, such as filters and vulnerable parts of spray guns, the replacement cycle is relatively long and the cost is controllable. Overall, compared with the improvement in production efficiency it brings, the subsequent operation cost is not high and can create a good cost performance for your enterprise.
