Wood preparation
The wood to be bonded must be of uniform thinckness and the surface must be free from oil ,fat ,dust or other deposits (Thickness deviation <0.1mm)
Glue mix
1) Mixture Rate:
Weight: 2 portion powder to 1 portion water
Volumn: 4 portion powder to 1 portion water
2) Dissolved Method
a. Put the powder into a clean container. Add 2/3 water and blend it until all have been dissolved.
b. Add the surplus and mix it about 2 to 5 minutes.
c. The usage time of proper liquor should about 2 hours (Room Temperature)
Glue spread
The glue-spread rate is dependent on the surface of the adherents .Normal glue spread is 200-300 g/m2 .On very smooth surface(e.g medium density fibreboard ,MDF) or in foil laminating ,lower glue spread may be used .On the other hand ,e.g on rough veneer surfact ,more glue must be applied .
