How to apply PUR glue to sealing edges

Applied to furniture customization in the use of high frequency of panel furniture, its manufacturing process there is a process that can not be ignored - edge sealing!
 

The edge sealing process needs to seamlessly fit the edge sealer to the board through the edge sealer, in this link, the edge sealer plays a major role, not only to improve the quality and grade of the furniture, but also to improve the manufacturer's production efficiency and reduce the difficulty of board correction. Therefore, the board and edge sealing strip is good, if the later bonding work is not appropriate, or will make the furniture products greatly reduced.
Traditional Edge Banding VS PUR Hot Melt Adhesive Edge Banding

Traditional edge sealing using white glue, latex and other water-based glue, odor, containing benzene, damage to the human body; and easy to fall off the phenomenon seriously affects the quality of the

product, and now the use of environmentally friendly requirements of the standard hot melt adhesive bonding, is to avoid these problems.
PUR (Polyurethane Reactive), known as moisture-curing reactive polyurethane hot melt adhesive, its mechanism of action is the reaction of polyurethane prepolymer and moisture in the air, curing cross-linking and the formation of a stable chemical structure. Chemical corrosion resistance and aging resistance, suitable for plastic, metal bonding, widely used in electronics, automotive, textile, woodworking, mechanical and electrical, aerospace and other national economic fields.

The use process of PUR hot melt adhesive in edge sealing

1) first see if the vacuum state of PUR hot melt adhesive package is intact, if you find any air leakage, please stop using it.

2) PUR hot melt adhesive needs to return to room temperature for a few hours (depending on the storage temperature).

3) PUR hot melt adhesive is preheated without removing the aluminum foil (label) (generally 5 minutes to 15 minutes), or the PUR hot melt adhesive can be preheated in the oven with the package intact, with a recommended control temperature of 100 °C.

4) After the PUR glue is removed from the preheating cylinder, the crust at the top and tail of its hose must be picked out, after which the glue can be used.

5) All workpieces to be glued should be cleaned and ensure that they are dry and show no visible signs of oil or dust contamination.

6) The last step is to seal the edge of the workpiece to be glued with PUR hot melt adhesive.
