D      Usage Method:

1.      Pretreatment for gluing wood material:

a)       Moisture Content reach to 10 + 2%

b)       Remove Knots, Cracks, oil stain and resin etc.

c)       Wood surface must be flat and smooth. (Thickness Tolerance0.1mm

2.      Mixture of Glue

a)        Mixture Ratio(weight):    UF Powder: Water=1: ≤0.6

b)       Dissolution Method:

Put 2/3 of the total needed water into mixer, and then add UF powder in. Switch on the mixer with speed of 50~150 rotations / minute till to being completely dissolved.

Put the remained 1/3 water in mixer and churn about 3~5minutes till to being completely dissolved.

c)        The user could add hardener into the mixed liquid glue depend on the actual requirement, and control workable period of dissolved liquid glue.

3.      Gluing Operation:

 1)     Gluing Quantity: Depend on different wood material and working temperature. Generally, 2 sides sub is: 200~300g/m2.

 2)     Required Press Condition:

The pressure and Process Time depend on different wood species and process temperature. Please refer to below instruction:

4.      Maintenance:

After pressure relief, the glued board could be used on the second day. In winter, board must be maintained at least 12 hours under temperature above 20 before put into process.

5.      Heat Solidification Operation:

The glued board with above mentioned pressure for 5~7minutes under temperature 100-110. It could be used after release of press.

E       Note:

1.        The goods should be stored in a dry, ventilated location. Avoid direct sunshine and moisture.

2.        The package should be sealed again immediately once the pack of UF powder has been opened to avoid moisture.
