What are the factors that affect the bonding effect of the glue?

What are the factors that affect the bonding effect of the panel glue:

 

1. Substrate that affects the bonding effect of the panel glue: The surface treatment of the surface treatment substrate should be carried out within 24 hours before the glue is applied. A good quality surface will achieve the close contact of the substrate and the fineness of the glue line.

 

2 , the amount of cloth that affects the bonding effect of the board glue: the substrate is cork, hardwood, generally single-sided coating, the amount of cloth is 200-300g/m2 . A suitable amount of cloth should be such that when the glue line is squeezed, the extruded glue is continuously uniform in the form of beads or thin lines.

 

  3, the water content of a substrate adhesively bonded Factors affect puzzle effect: After drying the wood after the resurgence of natural, water content should be controlled at 8 - 12% less. Excessive water content is not conducive to the penetration and solidification of the glue; when the moisture content of the wood is less than 8% , it may cause excessive penetration of wood and cause cracking of the bonding surface, which may not cause good bonding strength. And may cause defects in the glue line, such as the glue line sinking or convex.

 

  4. Pressure and pressing time of factors affecting the bonding effect of the panel glue: sufficient pressure and pressing time must be ensured. The proper pressure is beneficial 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 and external factors of the substrate itself.
