Microwave Oven Tunnel Drying Equipment Product Line for Wood and Furniture

详情

Function:To solve the drying problem of high-end furniture enterprises in the coating of whole furniture water-based paint ,such as :American Furniture, European Furniture,Rosewood furniture, Hotel Furniture etc,

Feature:
Rapid drying : Compared with conventional hot wind drying, infrared drying, the time of drying water-based paint is less than *5 minutes,only 1/3 of them.

Uniform drying thoroughly: the electromagnetic wave has a certain penetration,and the cracked antenna feeding energy can guarantee the uniform distribution of electromagnetic waves.whether the furniture surface,or the drawers, the plywood and the base, can heat and evaporate water rapidly through absorbing the energy.

Non-distortion:The furniture will absorb water from the water-based paint after spraying the water-based paint. Owing the conventional hot wind ,infrared and other drying methods dry the object from outside to inside , it is easy to make water-based paint surface conjunctiva,slow down the speed of the water evaporation and increase the risk of furniture deformation caused by the water absorbing. But  owing microwave heats the outside and inside simultaneously and the furniture itself will form a positive temperature gradient( owing the temperature of the timber core is slightly higher than the surface ,the water in the water-based painting is not able to be absorbed into the timber),so the deformation of furniture is tiny.

Increased adhesion, high clarity: Owing there is no intermediate layer between the furniture and the lacquer film , microwave drying can make the water - based paint adhered to furniture firmly, so the clarity is much better.

The quality of the lacquer film surface is much better:Owing the electromagnetic wave vibrates at *4,*******0 beats per second and speed up the mutual collision of the water-based paint molecule , it can make the lacquer film more uniform and denser. The drying time is short, so the dust particles of the lacquer film surface are obviously less .

cover a small area:Two production lines of primer coat and top coat cover about 1,**0 square meters;

Energy conservation and environmental protection:The electromagnetic heating needn't preheat and heat the environment and air ,but effect at once,power adjustable, transmission speed adjustable, no thermal inertia residues,compared with the infrared drying can save energy more than*0%.

Flexible operation: PLC automatic control system can control the surface temperature, ambient temperature, ambient humidity and process curve automatically,meanwhile, it can realize one- boot function.

Primer coat process
Primer online→primer spraying→ natural flowing flat→ microwave drying  Offline cooling→ primer polishing→ primer respraying

Top coat process
Top coat polishing→Offline cooling→microwave drying→infrared flowing flat→ top coat spraying→ top coat online→ embellish/brush color→ top coat repainting→ packaging products

The forming process of the lacquer film:
The water evaporates,the particles deform and coalesceThe water continues to evaporate,the polymer microparticle deforms and causes pressure to each other, then agglutinates,fuses and forms continuous lacquer film.The water continues to evaporate, then the pressure of particles causes the polymer chain spread to each other step by step and gradually , make the membrane homogenization.
Controlling water, the water-based paint furniture will be safer, more reliable and more practical
Only The water evaporates completely, the lacquer film can get adhesion;
Only The water evaporates completely, the lacquer film can be transparent.;
Only The water evaporates completely, the lacquer film can protect furniture;
Only The water evaporates completely, the lacquer film can sturdy and durable.
