Make sure the substracts in well prepare Lacquer must be well mix with proper thinner and check

viscosity , when hardener in use, make sure its well mix and be sure of pot-life

Make sure the application equipment is properly clean and right nozzle of spray gun and output of lacquer paints be adjusted.

SANDING & PROFILING

Sanding machine 3 belt: 170, 180, 240 Orbiter sanding machine 170, 180, 240, 320, 400, 600, 1500 Brush sander Dumpling sanding Auto sanding for edges R2, R3, edges CNC rounder (Profiling machine)

M.D.F PROBLEM E 2, E1, E 05, E0 Emission

of formaldehyde Pentachlorophenol chemical Glue content formaldehyde

on veneer (industrial flour water urea formaldehyde glue)

Thickness of veneer Gap of veneer joint Delaminating of veneer Glue not resistance to

solvent (cause pregnant) Edges delaminate cause by

uneven glue spread or too low viscosity

Uneven sanding cause surface to look weave on high gloss finishing

Swelling Porosity on edges after profile

(high absorption of lacquer.) Paper lamination easily over

sand when after lacquering. PVC vacuum an M.D.F board

(Proper glue to be used) Migration of stain from pine

wood fiber M.D.F when white painting is applied.

Rubber spot too many Too high humidity Too high moisture content.

Terms use in mixture

1. Single pack: just dilute with thinner2. Ready to use: just spray (RTU)3. Atmosphere cure or self crosslink : react with oxygen

and crosslink 4. Two pack : part A & part B (hardener pot-life applied

PU, NC)5. Three pack : part A (lacquer); B (mek peroxide); C

(cobalt-diluene strene monomer)6. U.V cure by UV lamp7. Open grain and full grain cover; semi open grain.

13

Recommended viscosity for different application

Viscosity (hand spray recommended) 12 second to 13 second (Ford cup 4) ;

Viscosity airless spray – 18 second (Ford cup 4) Viscosity curtain coater & rainbow – 33 second (Ford cup 4) Disk electrostatic – 9 second Roller coater – 2 minute Dipping – 10 second

14

Thinner is very important 1. To achieve better dilution.

2. Too slow drying cause stacking problem. Too fast drying causing flow problem.

3. Good electrostatic charge

4. Blushing

5. Orange peel

6. Fast dry (pin hole) in two pack system

7. Using recycle thinner may cause many problem
