Advantages of binding with custom lift-up flaps book binder from khedmehcom's blog

Adhesive * has no mold, no moth, not afraid of rat bite performance, to ensure that custom lift-up flaps book is protected from microbial and animal erosion when stored. The mixture not only has various requirements for the finished product, but also its solution properties can not be ignored. Adhesive working solutions also have certain requirements for viscosity, viscosity and concentration, which must be adapted to the material and drilling conditions. For example, the stickiness of the paper with high adhesion smoothness is larger than that of the paper with low dry smoothness, and the glue of the lacquer cloth is thicker than that of the cloth with the cover.

custom lift-up flaps book adhesive requires a certain viscosity, so that the cover material can be attached to the book block for at least 5 to 8 minutes without the force of the cover material returning to the original shape of the two dead compound off contact, this time is the necessary time to complete the binding work. The viscosity of the dry mixture mainly depends on its cohesion strength. The cohesion strength of the adhesive is large to ensure that the custom lift up flaps book is not extended, but the adhesive with too much cohesion strength is not easy to spread on the surface of the twist.

For the adhesive, it is necessary to ensure that the adhesive has good fluidity, so that it can be filled in all the concave places on the surface of the bonded object, that is, the surface of the bonded object is covered. The nature of the reaction adhesive fluidity is viscosity, in many industrial areas of adhesive application, it should be noted that the solvent-based adhesive will change with the solvent volatilization, if the water or organic solvent in the adhesive may evaporate, then the adhesive will be more and more thick, if not take appropriate measures, At the beginning, the adhesive with appropriate viscosity may have a series of failures such as uneven distribution or insufficient penetration of the adhesive to the bonded material due to excessive viscosity.

custom lift-up flaps book adhesives should be free of unpleasant smells and do not release harmful gases when bonding. Acid alkalinity is also moderate, or weak alkalinity, if there is free acid or too strong alkalinity in the glue, it will also affect the bonding fastness, or damage the material to be bonded. The composition of the adhesive should not contain substances that can make the ink fade, otherwise it will also affect the beauty of the custom lift-up flaps book.
