Detection method of edge banding

Visually inspect whether the edge banding is consistent with the color and texture of the board used, or whether it is consistent with the designer's requirements.

Check whether the surface of the edge banding strip is smooth and flat, and there are no noise spots. If there are specks or fine hairs, it may be made of recycled debris PVC. Check that the back of the edge banding strip is flat. You can use a flat blade to clamp the edge banding horizontally to see if it is in a straight line, if not, there will be thick glue lines on both sides of the edge banding. If the back of the edge banding strip is flat, and there is still a very thick glue line after the edge banding, it can be checked according to the following methods: Check whether the sawn surface of the board is flat. If the specifications of the upper and lower saw blades are different when sawing the board, there are small steps on the saw surface when sawing the board, which affects the edge banding. Check if the hot melt glue is too thick. Check whether the thickness and pressure adjusted by the edge banding machine are coordinated. Use a short section of edge banding and then tear it vigorously to check whether the adhesive strength of the edge banding and the hot melt is reasonable and uniform. If the strength is not enough, it is necessary to check whether the hot melt temperature of the edge banding machine meets the use standard, which can be compared with the adhesive introduction in paragraph 3 of the "PVC wood grain edge banding strip" in the first article.

Whether the sides of the plate are uniform after trimming, if there is a jagged shape, it may be due to the following reasons: The trimming knife is too blunt; The edge banding strip is too hard; The edge banding strip contains too much calcium carbonate. If the edge banding is scratched with a fingernail or other tools, if it is damaged, the surface wear resistance and hardness of the edge banding do not meet the standard, which proves that the quality of the edge banding is unqualified.
