The term "hot melt adhesive" refers to glue that melts when it is exposed to heat; as a result, hot melt glue sticks and hot melt glue particles are frequently utilized in the process of day-to-day glueing. Gluing with a glue gun This specific method of gluing is the standard method for applying hot melt glue sticks. It involves the use of a glue gun. The majority of the time, a hot melt glue stick with a diameter of 7 millimeters is melted using a hot melt glue gun that has approximately 20 watts of power, and the glue is then applied to the surface.
Roller gluing The pearl cotton industry makes substantial use of this particular method of applying glue, which involves using rollers. Following the steps of positioning the EPE pearl cotton on the roller and heating the hot-melt rubber particles in the roller hot-melt adhesive machine, use the roller to apply an even layer of the melted hot-melt adhesive to the surface of the EPE pearl cotton. The application of this kind of glueing method is best suited for gluing objects that are flat and of equal height; however, this method can also be used to glue some objects that are uneven and have an irregular shape.
In the process of automatic packaging, it is common practice to make use of glue that melts when heated. After it has been heated, evenly touch the surface of the object to be bonded with the melted hot-melt glue while applying pressure. This kind of hot melt adhesive needs to be cured as quickly as possible so that it can be used on automated equipment; otherwise, it won't work. This includes the automatic sealing of cartons, the sealing of po hot melt adhesive film cartons, handbags, air filters, and other products of a similar nature. The application of this type of glue is best accomplished through the use of a glue sprayerAfter the adhesive has been subjected to heat and melted, the glue can be spread across the surface of the adhesive using a brush or other implements. This step is necessary after the adhesive has been heated.
