How to use hot melt adhesive correctly?
Sometimes customers will ask: “How to use hot melt adhesive?” Or it will be found that some customers are not standardized in the process of using hot melt adhesive, which will affect the bonding effect. Today we will explain how to use hot melt adhesive correctly.
The hot-melt adhesive is a solid block at room temperature. When using the hot-melt adhesive, it is necessary to heat and melt the hot-melt adhesive into a liquid state, and then carry out construction. Hot melt adhesive heating generally needs to be equipped with a hot melt adhesive machine for heating. There are two advantages to using a hot-melt glue machine for construction: first, it is not easy to damage the glue when the hot-melt glue machine is heated evenly; second, the hot-melt glue machine is more convenient for construction, and you can choose glue dispensing, over glue, spray glue and other construction methods, the production efficiency is higher;
The following points need to be paid attention to when using hot melt adhesive:
First, the heating temperature, the heating temperature of the hot melt adhesive is generally 130 ℃-180 ℃, the temperature is too high or too low will have an adverse effect on the bonding effect, so you need to consult the hot melt adhesive manufacturer during construction to choose the right one. heating temperature.
Second, please close the plastic bucket cover during the production process to prevent debris or ash layer from falling into
Third, it is forbidden to mix different types of hot-melt adhesives. When changing products, you need to clean the hot-melt adhesive in the glue bucket first, and then put new glue.
