Stainless steel airport chair is mainly a back of stainless steel plate.It use special high speed CNC punching machine with special punching die for punching. After removing edge, straight, It use the large-scale hydraulic machine and special cold pressing mould pressing one.

 

The armrest, leg, brackets are used aluminum alloy, the bottom beam is the use of steel pipe.

 

After the stainless steel plate is treated with antirust, the detailed technological process of electrostatic powder spraying is as follows

 

1, degreasing (alkaline degreasing agent)

2, derusting (phosphoric acid, chemical raw materials)

3, neutralization (soda ash)

4, wash (clean water three times)

5, phosphating (ash phosphating agent)

6, dry water

7, spraying (divided into thermosetting powder coating, electrostatic spraying, acrylic acid, oil)

8, curing (180 degrees C/15)

9, cooling
