Why does pearl cotton hot melt adhesive have wire drawing? During the process of gluing pearl cotton with a drum hot melt glue machine, some customers may find that the hot melt glue has a wire drawing phenomenon. The wire drawing of the hot melt glue not only affects the construction efficiency, but also affects the appearance of the product, and may even affect the bonding effect. So how to solve the problem of hot melt adhesive wire drawing?
Possible reason 1: The temperature of the glue tank in the drum hot melt glue machine is too low
Reason and solution: Low temperature will increase the viscosity of hot melt adhesive, that is, the thinner it is, the easier it is to draw. The melting temperature of the hot melt adhesive machine can be appropriately increased to reduce the viscosity of the hot melt adhesive. It should be noted that the temperature of the hot melt adhesive machine should not be raised too high to avoid carbonization of the hot melt adhesive.
Possible reason 2: The glue is too thick
Reason and solution: The thicker the pearl cotton hot melt adhesive, the easier it is to draw. If the thickness of the adhesive is thin, the speed can be increased, and the higher the speed, the less adhesive is needed. You can also adjust the thickness knob to look thinner. Or adjust the pressing height during the gluing process, not too low or too low. The easier it is to draw.
Possible reason 3: The viscosity of pearl cotton hot melt adhesive is too high
Reason and solution: The higher the viscosity, the easier it is to draw. Replace low viscosity hot melt adhesive particles or replace special formula non brushed hot melt adhesive particles
Ordinary hot melt adhesive will draw, but the difference is obvious. When encountering wire drawing problems, there is no need to be nervous.

In the rapidly developing binding industry, the requirements for book binding are also increasing day by day. Therefore, many binding factories choose high-quality, non drawing, and high bonding strength hot melt adhesives. High performance hot melt adhesive has also become an important guarantee for the quality of books. For example, Senlai book hot melt adhesive […]
The flowability of hot melt adhesive particles has an impact on the quality of glue and adhesive. Hot melt adhesive has poor fluidity and can also cause stretching problems or mismatch with mechanical efficiency. 1. Sol temperature; Hot melt adhesive is very sensitive to temperature, and changes in temperature can alter the structure of the […]
How to solve the troubleshooting of packaging hot melt adhesive? Hot melt adhesive is some of the most advanced adhesives used today, but even with daily maintenance, adhesive problems can still occur. This guide aims to help manufacturers overcome some of the most common adhesive challenges faced in packaging applications. There may be various reasons […]
Why can’t EVA hot melt adhesive stick? Hot melt adhesive is a widely used adhesive in industrial production processes, but there may be inevitable non stick situations during application. So what are the reasons that affect the viscosity of hot melt adhesive? It is mainly divided into the following three categories: 1 EVA hot melt […]
