The differences between cold and hot splicing pulley lagging

The differences between cold and hot splicing pulley lagging

Before distinguishing two methods, we should have a understanding on them.
Cold splicing pulley lagging, the roller doesn’t have to be disassembled, we can brush glue on it after grinding the roller, then we bond the rubber sheet to finish pulley lagging.
Hot splicing pulley lagging, which means we do pulley lagging in hot splicing methods, first of all, we have to disassemble the roller, then we brush the glue, bond the rubber sheet, also we have to heat and press the roller with the vulcanizing press, then finish the pulley lagging.

From above description, we can see that about hot splicing pulley lagging, we have to disassemble the roller and with the help of vulcanizer can finish it, cost man power and energy, however, cold splicing pulley lagging is fast and easy operation, except this, what is the differences between them?

What is the differences between cold splicing pulley lagging and hot splicing pulley lagging? (as Ramimtech for reference)

Metal roller bonding strength: the bonding strength is 3-8N/MM, but Ramimtech cold splicing pulley lagging is 12N/MM.
Pressure: the pressure is 6-8KG/cm2, the pressure of Ramimtech cold splicing pulley lagging is 50KG/cm2.
Abrasion resistance: low rubber density,bad wear resistance. Ramimtech cold splicing pulley lagging is high rubber density, good wear resistance.
Life usage: Ramimtech cold splicing pulley lagging is many times than usual pulley lagging.
Friction factor: low adhesion between rubber and conveyor belt, conveyor belt cold splicing rubber has high adhesion with conveyor belt, high friction factor.
Rubber hardeness: usual pulley lagging is quick aging which cause rubber too hard and cause materials stickiness, cold pulley lagging has good elasticity, good property for anti stickiness.


From above, we can see that cold splicing pulley lagging has great ascendancy, more and more enterprises begin to apply this method, but it has high requirement on materials. So here we suggest Ramimtech cold splicing pulley lagging sk313 and pulley lagging rubber sheet 12mm.

Cold splicing pulley lagging glue sk313 is a double-component, high intensity glue, which contains 1kg glue and 40g hardener. Whose excellent bonding strength that far more exceed Germany DIN standard and have the same grade with hot splicing methods. The bonding strength can reach to 10000CPS.

12mm pulley lagging rubber sheet is a new product in anti-skidding device for driving roller. The surface has semi-cured layer, from cold splicing glue bonding, combine closely with roller, no worry about the degumming situation.
