Hot melt adhesive product itself is solid, easy to package, transport, storage, no solvent, no pollution and non-toxic; And the production process is simple, high added value, bonding strength, speed and other advantages are favored. How to analyze the cause of hot melt adhesive drawing carbonization?

Especially at high temperatures. Hot melt glue machine after a long time will see a layer of black material around the rubber groove, and these are carbides. Now the generation of carbides will mainly have the following points:

1, plastic box temperature makes the use of some equipment time is too long, so also appeared in the temperature control of the fault, but the actual just below show the temperature, temperature or temperature on the high side a lot of will have the effect of control, causing gum damage occurs, so just appear the phenomenon of wire drawing, then after a long time will produce the carbide, which causes the destruction of equipment appear jams and colloidal.

2, hot melt glue glue box surface layer gradually carbonization situation;

3, because the thermal stability of the hot melt adhesive itself is not very good;

4, hot melt glue in the plastic box for a long time of repeated heating;

5, there are two different kinds of hot melt glue in the glue box.
