Paint Spraying Water Curtain Cabinet - High-Quality Air Purification Solution from China Suppliers and Factory
What is the working principle of the water curtain cabinet?
It uses a water curtain to capture and filter paint mist and exhaust gas. The water curtain mixes with the paint mist through the membrane effect and viscosity of the water, separating particles from the air so they fall into the water tank.
What are the main structural components of a water curtain cabinet?
The cabinet is typically composed of a pool, a water curtain plate, a top plate, a side plate, a water circulation system, and an exhaust system.
How does the equipment protect the environment and operators?
It prevents paint mist and exhaust gas from spreading outside the working environment, effectively reducing the environmental impact of painting operations and protecting the health of operators.
What is the waste paint removal rate?
Through the integrated water circulation system, the removal rate of waste paint can reach more than 99%.
What materials are used to manufacture the water curtain cabinet?
The main cabinet body is usually made of stainless steel and is electrostatically sprayed and painted. The water tank and overflow tank are mostly made of stainless steel plates.
Is the water curtain cabinet durable and rust-resistant?
Yes, the stainless steel and electrostatic spray painting construction provides excellent corrosion and rust resistance, ensuring long-term durability and stability.

Assembly line process flow
Step 1: Pretreatment
This is the preparatory work before painting, the purpose is to remove impurities such as oil, dust, rust on the surface of the workpiece, and increase the adhesion between the coating and the surface of the workpiece.
Step 2: Drying moisture
After the pretreatment step is completed, some moisture and possible tiny particles will remain on the surface of the workpiece. The principle of drying moisture is mainly to evaporate the moisture on the surface of the workpiece by heating, ensuring that the surface of the workpiece is dry before entering the powder spraying link so that the powder coating can be evenly attached.
Step 3: Electrostatic powder spraying
Electrostatic spraying is the core link of the powder coating assembly line. In this process, the powder coating is fed into the spray gun, and the spray gun generates high-voltage static electricity through an electrostatic generator. When the powder coating passes through the spray gun, it will be charged. Because the workpiece is grounded, the charged powder coating is evenly adsorbed on the surface of the workpiece under the action of electrostatic attraction.
Step 4: Baking and curing
Baking and curing The sprayed workpiece then enters the baking and curing chamber. Under high temperature, the resin and curing agent in the powder coating react chemically to form a strong and durable coating. This process not only fixes the coating, but also gives it excellent corrosion resistance and weather resistance.
Step 5: Post processing Finally
Post-stage processing Finally, the workpiece goes through post-processing steps such as cooling, inspection and packaging to ensure that the coating quality meets the standards and is ready for shipment.
