Painting equipment

The core function of spray painting equipment is to evenly atomize and adhere the paint to the surface of objects, and it is widely used in industrial manufacturing, maintenance, construction and other fields. The following is a detailed description of its main components and typical application industries:

1.The main components of spray painting equipment

Feeding system

-Paint containers: storage tank, pressure tank (equipped with gravity/siphon spray gun).  

-Material transfer pump: gear pump, plunger pump (used for high-pressure airless spraying), ensuring stable transportation of paint.  

-Filter: prevents impurities from clogging the nozzle.  

Atomization system (core component)

-Spray gun/nozzle:

-Type:

-Air spray gun (compressed air atomization) - fine spraying.  

-High pressure airless spray gun * * (hydraulic atomization) - high viscosity coatings (such as anti-corrosion paint).  

-Electrostatic spray gun (electric field adsorption coating) - efficient and energy-saving paint (for automobiles and metal parts).  

-Key components: nozzle (diameter determines flow rate), air cap (controls atomization shape), needle valve (adjusts paint output).   

Power and control system

-Compressed air system:

-Air compressor, air storage tank, oil-water separator (ensuring dry and pure air).  

-Pressure regulator: precise control of spraying pressure (HVLP spray gun requires low pressure).  

-Controller (automation equipment): PLC programming controls the path of the robotic arm, paint flow rate, etc.  

Conveyor and Recycling System

-Conveyor device: conveyor belt, rotary table (assembly line operation).  

-Paint recycling:

-Water curtain spray booth: Water flow absorbs spray paint mist.  

-Dry filtration system: filter paper/filter cotton captures paint residue (suitable for small batches).  

-VOC treatment equipment: Activated carbon adsorption/combustion method for treating organic waste gas (environmental requirements).  

Auxiliary equipment

-Drying equipment: infrared baking lamp, drying oven (accelerated curing).  

-Protection system: explosion-proof lighting, ventilation devices, fire-fighting facilities.  

2.Main application industries

Automobile manufacturing and maintenance

-Automobile production line: electrophoretic primer+robot electrostatic spraying topcoat (uniform and efficient).  

-Car repair shop: HVLP spray gun (high transfer rate, reduces paint flying) repairs car bodies.  

Furniture and wooden products

-Wooden doors and cabinets * *: airless spray coating thick paint (polyester paint), UV paint curing line.  

-Customized furniture: Handheld spray gun for processing irregular surfaces.   

Metal manufacturing industry

-Construction Machinery: High pressure airless spray anti-corrosion primer (epoxy zinc rich paint).  

-Hardware: Electrostatic spraying (batch processing of small parts such as screws and shelves).  

Electronic products

-Shell spraying (mobile phones, computers): Automated spraying line+UV curing to achieve matte/metallic texture.  

-Insulation coating: Three proof paint (moisture-proof, anti-corrosion) sprayed.  

Aerospace

-Aircraft skin: airless spray aviation primer, strictly controlling thickness (anti-corrosion and compressive).  

-Engine components: High temperature paint spraying (must withstand 500 ℃ or above).  

Architecture and Steel Structures

-Bridges and storage tanks: High pressure airless spraying thick slurry epoxy paint (anti-corrosion and wear-resistant).  

-Exterior walls of buildings: sprayed with real stone paint and fluorocarbon paint (durable and UV resistant).  

Plastic products

-Toy and home appliance shells: spray painted with water-based paint (environmentally friendly and low VOC).   

3.Key points of safety and environmental protection

-Personal protection: gas mask (organic solvent resistant), anti-static clothing (flammable environment).  

-Explosion prevention: Explosion proof electrical appliances and combustible gas alarms are required in the paint booth.  

-Waste disposal: Paint residue is classified as hazardous waste (HW12) and requires professional recycling.
