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 .Pressure (on normal temperature)Woodconifer woodenbroad-leaved woodenTemperature5-25°C >25°C5-25°C >25°CGelatinizing quantities(two sides)g/m2200-250 250-300200-250 250-300Pressurization (MPa) 0.8-1.0 0.8- 1.01.2-1.5 1.2- 1.5 Pressurization time(h)>8 >7 >8 >8Maintenance:Normally the maintenance time is 8-12 hours , but in winter it must be maintained more than 12 hours over 20°C.Heat press3-7 mins at the 100°CPackaging 2-ply bags with inner plastic bag and outer fabric bag25kg/bagNote This power is easy to be damped; it will concert into pieces rapidly after damped, lose use and liquidity,Normally it require damp-proof packaging. Tie up fast to seal the bag when it is inexhaustibility.
