    Product Detail

    1. Working Principle
    The working principle of the water curtain cabinet for painting is to use a water curtain to capture and filter the paint mist and exhaust gas generated during the painting process. When the painting operation is in progress, the paint mist and odor sprayed from the spray gun will be blocked by the water curtain in the water curtain cabinet. The water curtain mixes with the paint mist through the membrane effect and viscosity of the water, so that the paint mist particles are separated from the air and fall into the water tank.
    2. Structural Composition
    The water curtain cabinet is usually composed of a pool, a water curtain plate, a top plate, a side plate, a water circulation system and an exhaust system. The pool is used to collect paint mist and wastewater, the water curtain plate is responsible for forming a uniform water curtain, and the top plate and side plates constitute the main frame of the cabinet. The water circulation system ensures the continuous circulation of water, and the exhaust system is used to exhaust the filtered air to the outside.
    3. Environmental Protection and Safety
    The design of the water curtain cabinet can effectively reduce the impact of painting operations on the environment and prevent paint mist and exhaust gas from spreading outside the working environment. Through the water circulation system, the removal rate of waste paint can reach more than 99%, greatly reducing the impact of waste paint on the environment. At the same time, the use of water curtain cabinets also helps protect the health of operators.
    4. Materials and Durability
    The cabinet body of the water curtain cabinet is usually made of stainless steel and electrostatically sprayed and painted, which has good corrosion resistance and rust resistance. The water tank and overflow tank are mostly made of stainless steel plates to ensure the durability and stability of the equipment.
    Frequently Asked Questions
    What is the working principle of a water curtain cabinet?
    It uses a continuous water curtain to capture and filter paint mist and exhaust gases. The viscosity and membrane effect of the water separate the paint particles from the air, causing them to fall safely into a water tank.
    What are the main structural components of the equipment?
    The main components include a pool for collecting wastewater, a water curtain plate, top and side plates forming the frame, a water circulation system, and an exhaust system to release filtered air.
    How efficient is the water curtain cabinet at removing waste paint?
    Thanks to its efficient water circulation system, the removal rate of waste paint can reach more than 99%, significantly minimizing environmental pollution.
    Does the water curtain cabinet protect the operators?
    Yes. By preventing paint mist and harmful exhaust gases from spreading outside the working area, it greatly helps in protecting the respiratory health and overall safety of the operators.
    What materials are used to manufacture the cabinet body?
    The cabinet body is typically constructed from stainless steel and features an electrostatically sprayed and painted finish. This combination provides excellent resistance against corrosion and rust.
    Why are the water tank and overflow tank made of stainless steel?
    Stainless steel plates are specifically chosen for these components because they are in constant contact with water and chemicals, ensuring long-term durability and structural stability.

    Assembly line process flow

    section-block-demo215-case01-case-slide-item-desc

    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.

    Step2 Drying moisture (1)

    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

    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

    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

    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.
