The adhesive type on the reticle roll of the dry compound machine

The selection of the belt buckle for the belt buckle of the dry type composite belt joint is closely related to the thickness of the belt and the strength of the belt. The belt buckle connection is not reliable and the strength is less than the strong band, which will cause the adhesive tape to be broken at the joint connection.
Improper tension control of dry compound machine can cause a series of problems, such as membrane crimping, film wrinkling, bag making difficulty, peeling strength drop, bag deformation and so on. The setting of tension is determined by the type, width, thickness, environment and temperature and humidity of the oven. There are three kinds of mesh roller of dry type compound machine, that is, cone type, edge type and oblique line type. The oblique line is used for high precision transfer adhesive coating. In dry compounding, the tapered and prismatic roller is common.
PVC or PVG flame-retardant adhesive tape is used in underground coal mine for long-term operation of dry type composite machine. The long run belt surface is subjected to water immersion, wear, coal flow impact and plastic deformation, which will lead to thin, brittle and fatigue damage. With the increase of coal consumption and running time, the breaking tension of the strip decreases.
