repair strip and cold vulcanzing adhesive
Repair strip is the material during conveyor belt repair, mainly used for
conveyor belt partly damage and long distance puncture repair, so
the quality of conveyor belt bonding is greatly related to the
There are many kinds of conveyor belts, when we face these conveyor
belt with so many textures, whether there is one kind of adhesive
can satisfy the bonding process?
Ramimtech cold vulcanizing adhesive SK313, whose excellent bonding strength that far more exceed
Germany DIN industry standard, which can satisfy the special
requirements and can have the same grade with hot splicing process,
cold vulcanizing adhesive Sk313 that is suitable for rubber to
rubber, rubber to metal, rubber to fabric and fabric to fabric,
mainly in the area of conveyor belt system repair, rubber joints,
pulley lagging and liner rubber bonding area.
Repair strip, as the common material, suitable for cold vulcanizing
adhesive SK313, cold vulcanizing adhesive SK313 have the cold
vulcanization reaction with repair strip CN layer, and make repair
strip tightly combine to conveyor belt surface.
On site operation methods of cold vulcanization adhesive SK313
1. Choose the repair strip that should be 2 to 3 cm wider than
Ramimtech repair strip, put the damaged part as the center and mark
it, then make preparation before grinding.
2. While grinding, use high power angle grinder L1202 together with
RIT Tungsten carbide buffing disc to grind the repair part, the
grinding thickness of ioint part should be thicker than repair
strip(such as 150 reinforced repair strip, the thickest part is
4.6mm,so the grinding depth should be 4.6mm), thus can avoid being
scraped by cleaner.
3. Clean the grinding part with high efficiency cleaning solvent
SK353 and dry it.
4. While waiting for the drying process, mix cold vulcanizing
adhesive SK313 and hardener UT-R40 evenly.
5. Brush the mixture on repair surface and till it dry to little
stickiness to finger back,remember to brush the surface evenly.
6. Brush the mixture on the blue CN layer of RIT conveyor belt
repair strip, and dry it to little stickiness.
7. While bonding the RIT repair strip, press it with hand roller.
8. After repair, brush again the mixture on RIT repair strip till
the CN layer cold vulcanize naturally.
9. When meet the splice joint with many repair strips, be careful
to the splice mode and operate as the photo shows.
