Water-soluble glue bonding principle:

Glue in the chemical composition in an aqueous environment. Polymer and glue (white glue in the vinyl acetate is a kind of oil derivatives) are rounded particles, average particle radius is between 0.5 ~ 5μm. Objects bonding rely on the tension between the polymer and the glue. In the glue, water is the carrier of the polymer and water carrying polymer and immersed slowly to the objects within the organization. When the glue in the water after the disappearance of the glue in the polymer and rely on each other pull the two objects tightly together. The use of glue, the excessive amount of glue will make the glue in the polymer and mutual crowded together; polymer body does not produce a good pull. Polymer and crowding each other, to form among the most attractive. Between the polymer and water are not easily evaporate. This is why in the bonding process "film thicker the glue felt connected to the effectiveness of the reasons for the worse". Excessive amount of adhesive, glue the play is "filling effect" rather than a bonding effect, the bond strength of bonding between the objects is not the glue, but glue and cohesion. "
