What specific problems will the poor sealing of the powder spraying room bring?
Poor sealing of a **powder spraying room (booth)** can cause several significant problems — both in terms of **efficiency** and **safety**. Here’s a breakdown of the key issues:
—
### 🔻 **1. Powder Leakage**
– **Problem**: Powder escapes into the surrounding area.
– **Impact**:
– Dust buildup in the facility.
– Contamination of other processes or equipment.
– Increased housekeeping/cleaning costs.
—
### 🔻 **2. Reduced Transfer Efficiency**
– **Problem**: Airflow patterns are disrupted, and powder doesn’t reach the part effectively.
– **Impact**:
– More overspray and wasted powder.
– Uneven coating thickness.
– Lower first-pass transfer efficiency (FPTE), leading to rework.
—
### 🔻 **3. Health and Safety Hazards**
– **Problem**: Airborne powder may escape into work areas.
– **Impact**:
– Inhalation risk for workers (especially fine powders).
– Increased risk of respiratory issues.
– Combustible dust hazard — risk of fire or explosion under certain conditions.
—
### 🔻 **4. Environmental Non-Compliance**
– **Problem**: Emissions escape into the environment.
– **Impact**:
– Violations of air quality regulations.
– Potential fines or shutdowns from environmental authorities.
—
### 🔻 **5. Filter and Ventilation System Overload**
– **Problem**: Dust escapes intended airflow paths.
– **Impact**:
– Filter clogging increases.
– Higher maintenance and replacement costs.
– Decreased lifespan of fans and filters.
—
### 🔻 **6. Product Contamination**
– **Problem**: Leaked powder can settle on freshly coated parts.
– **Impact**:
– Defects in surface finish (bumps, texture inconsistencies).
– More rejects or rework needed.
—
### 🛠️ Common Causes of Poor Sealing:
– Gaps or wear in door seals.
– Improper booth pressure balancing.
– Damaged or misaligned panels.
– Broken or loose duct connections.
