Compared with Nylon and fabric belt, steel cord belt is very strict when choose glue, why say it? Steel cord conveyor belt has very strong tensity, usual glue can not reach this kind of tensity and easily cracking.
So which glue can be used for steel cord belt hot splicing joint? ST conveyor belt hot joint need a kind of high bonding strength glue that guarantee the high joint strength for repair area.
Technical Data:
Viscosity : 10000cps
180° peeling strength:12MPa
Shear strength: 24MPa
Stretch strength: 30MPa

Ramimtech ST conveyor belt on site operation:
I ,Preparation before bonding
i, choose proper place( electric, well ventilated), rolling each belt to bonding area.
ii, vulcanizing equipment test
iii, vulcanizing equipment joint need cooling, because the specificity that different from other joint vulcanization, which need special equipment.
iii, test whether the joint tools are complete.
II, ST belt joint layer management and bonding
i, staged disposal for ST belt, then grinding the staged area with angle grinder and tungsten carbide buffing disc.
ii,clean the dust from grinding surface, then brush hot vulcanizing glue sk823 evenly on the grinding area.
iii, covered the brushed joint with Ramimtech uncured cover rubber and uncured tie gum and lay it evenly, then scratch the uncured cover rubber with wallpaper cutter and avoid bubble.
iiii, rise and press the joint area with vulcanizing press, when temperature reached 145℃, then need 40 to 45 minutes constant temperature, when temperature reached, stopped warm up.
iiiii, when temperature dropped, dismantle the vulcanizing press, adjust the nylon conveyor belt joint with rubber knife, then finish the vulcanization.
