How many spraying methods can be adopted in the spraying production line of the furniture industry?

Here are some common spraying methods:

Working principle: The paint is atomized into fine particles through a spray gun, and then sprayed onto the surface of furniture under the action of compressed air.
Advantages: The equipment cost is relatively low, the operation is simple, and it can obtain a uniform and fine coating, which is suitable for furniture of various shapes and materials.
Disadvantages: The utilization rate of paint is relatively low, more paint mist will be generated, which pollutes the environment, and good ventilation equipment is required.
Applicable scenarios: It is often used for spraying furniture parts with high requirements for appearance quality and complex shapes, such as cabinet doors and the surfaces of tables and chairs.

Working principle: The paint is pressurized by a high-pressure pump and then sprayed out through the nozzle of the spray gun. The paint is atomized under high pressure and adheres to the surface of the furniture.
Advantages: The spraying efficiency is high, it can spray high-viscosity paint, and a relatively thick coating can be obtained in one spraying, and the adhesion of the coating is strong.
Disadvantages: The equipment cost is relatively high, the sprayed paint mist is relatively coarse, and fine adjustments are required to obtain a good surface effect.
Applicable scenarios: It is suitable for spraying large areas of furniture surfaces, such as the side panels and top panels of panel furniture, as well as occasions with high requirements for coating thickness and adhesion.

Working principle: The spray gun or the sprayed parts are charged, and the paint particles are directionally adsorbed onto the surface of the furniture with the opposite charge under the action of an electrostatic field.
Advantages: The utilization rate of paint is high, which can effectively reduce the flying of paint mist, has good environmental protection performance, and the coating is uniform and flat with strong adhesion.
Disadvantages: The equipment investment is relatively large, there are certain requirements for the shape and material of furniture, and strict surface treatment is required.
Applicable scenarios: It is widely used for spraying the surfaces of metal furniture and plastic furniture, such as metal tables and chairs, plastic cabinets, etc.

Working principle: The solid powder paint is sprayed onto the surface of furniture through a spray gun, and then heated and cured to make the powder form a solid coating.
Advantages: The utilization rate of paint is high with almost no waste, the coating is solid and durable, has good wear resistance, corrosion resistance and weather resistance, and has good environmental protection performance.
Disadvantages: The equipment is complex, it is troublesome to change colors, and the spraying environment has relatively high requirements.
Applicable scenarios: It is often used for the surface treatment of metal furniture, such as anti-theft doors, metal bookshelves, etc., and can also be used for some wooden furniture with high requirements for environmental protection and durability.

Working principle: The paint is evenly poured onto the surface of furniture through curtain coating equipment, and the excess paint flows back to the paint tank for recycling.
Advantages: The utilization rate of paint is high, the production efficiency is high, and a uniform coating can be obtained, which is suitable for furniture parts with flat or regular shapes.
Disadvantages: There are certain restrictions on the shape of furniture, the equipment occupies a relatively large area, and regular maintenance and replacement of filters are required.
Applicable scenarios: It is mainly used for spraying the flat parts of panel furniture, such as table tops and cabinet doors.

Working principle: The paint is evenly coated on the surface of furniture by using rollers, and the thickness of the coating is controlled by adjusting the rotation speed and pressure of the rollers.
Advantages: The production efficiency is high, the coating is uniform, which is suitable for spraying large areas of flat surfaces, and there is little waste of paint.
Disadvantages: It can only be used for furniture parts with flat or regular curved surfaces, and cannot be used for spraying parts with complex shapes.
Applicable scenarios: It is often used in the production of panel furniture, such as the surface finishing of boards and the coating of wooden floors.
