1. The base material of the factors that affect the bonding effect of panel glue: surface treatment The surface treatment of the base material should be carried out within 24 hours before using the glue. Good quality surface will achieve the effect of close contact of the substrate and fine glue line.Puzzle


2. The amount of cloth glue that affects the bonding effect of panel glue: the base material is softwood and hardwood, generally single-sided glue, the amount of cloth glue is 200-300g / m2. The appropriate amount of cloth glue should be such that when the glue line is squeezed, the extruded glue is in the form of continuous and uniform beads or thin lines.

3. The moisture content of the base material that affects the bonding effect of the panel glue: After the natural moisture regains after drying, the moisture content should be controlled within 8-12%. Excessively high water content is not conducive to the penetration and curing of the glue; when the moisture content of the wood is less than 8%, it may cause excessive penetration of the wood and cause the lack of glue on the bonding surface to cause cracking, which cannot achieve good bonding strength , And may lead to defects in the glue line, such as sag or convex.

4. The pressure and pressing time of the factors that affect the bonding effect of the panel glue: sufficient pressure and pressing time must be guaranteed. Appropriate pressure is conducive to the penetration of the glue and the formation of the ideal glue line; sufficient pressing time can ensure that after the pressure is released, the glue has sufficient strength to resist the stress of the substrate itself and the influence of external factors.
