We proposed Lumina’s standard flat-fan pattern spray gun, the ST-6. They wanted to coat with a large amount of liquid, so we recommended the maximum nozzle size, 2 mm . They installed two spray guns on bottom and two on top. The four spray guns completely coated both sides of the 400mm wide lumber with anti-mold agent as it was being conveyed past them on a belt.
- (Spraying conditions)
- Atomizing air pressure: 0.05 MPa
- Liquid pressure: 0.05 MPa (using 20 L pressure feed tank)
As a result, their employees no longer had to coat the lumber manually, greatly improving work efficiently. Also, by setting the atomizing air pressure low at 0.05MPa, we created a soft mist that did not cause overspray.
This improved coating efficiency, decreasing the amount of anti-mold agent used.
