Do you have a good understanding of the parameters of the overheated glue stick

With the improvement of technology and the increase of people's daily demand, there are more and more varieties of hot-melt adhesive, and the performance requirements of products for hot-melt adhesive are higher and higher, especially in the metal, glass, wood, medical, electronic and electrical industries. Weiwang hot-melt adhesive is needed in all these aspects. We all know that hot melt adhesive is a thermoplastic adhesive material that is coated in the molten state and solidified after cooling. So how much do you know about the parameters of hot melt adhesive? Now let's take a look.

Thermoplasticity: thermoplasticity is under the action of heating or cooling.

Stability of hot melt adhesive: thermal stability refers to whether the glue material can withstand high temperature for a long time. Weiwang hot melt adhesive can achieve this.

Softening point of hot melt adhesive: refers to whether the hot melt adhesive material will become soft or close to the flowing temperature when heated.

Viscosity of hot melt adhesive: the index of fluid fluidity. If the viscosity is high, Liu Dongqiang is poor. There is a certain relationship between hot melt adhesive and fluid temperature, concentration and shear speed.

Opening time of hot melt adhesive: the maximum time interval between the application of hot melt adhesive and the throwing of items on the surface, so that the adhesive can have a good bonding effect within the opening time.

Curing time of hot melt adhesive: when the hot melt adhesive is in the working state, the adhesive is pressed between the two substrates to form a firm minimum time. Weiwang hot melt adhesive solidifies quickly.

The above are the parameters of hot melt adhesive. Weiwang hot melt adhesive is in good condition in work and completion.
