What is the Belt Refurbishment Process?

Mar. 05, 2020

As a Rubber Belt Manufacturer, share with you. Renovate old rubber conveyor belts that have been damaged, scratched, damaged with cores, or with reduced network bandwidth, and can be turned into rubber Rubber Conveyor Belts that can be reused. The key to the vulcanizate reconstruction is flue gas desulfurization, that is, without destroying the CC bond, the bond between the SS and CS are cut, the porous structure of the indoor space of the chemical cross-linking during the vulcanization process is destroyed, and part of the long chain and part chemical crosslinking reduces the molecular weight, converts the ductility of the vulcanizate into plastic deformation, and makes it capable of revulcanization. The flue gas desulfurization methods applied so far cannot restore the vulcanizate to the level of the original rubber, and it is difficult to avoid cutting the CS bond and the C--C bond, which promotes the process performance of the reclaimed rubber not reaching the level of the original rubber. The flue gas desulfurization and reconstruction of vulcanized rubber is a comprehensive result of several functions such as vulcanization reduction, thermal cracking polymerization, chemical effects, and mechanical equipment effects.

(1) Efficacy of mechanical equipment. Mechanical kinetic energy can destroy C-S, C-to-hair molecular chain segments, and as a result, the chemically crosslinked porous structure of vulcanized rubber molecules are broken. Milling can also separate the associations between the molecules and the surface layer of carbon black, and this cracking occurs mostly at lower temperatures.

(2) Thermal effect. The energy source accelerates the molecular fitness exercise, which may cause the molecular chain to rupture. Significant thermal cracking occurs at 80 ℃, and the cracking rate accelerates at 1500C. Since the temperature rises by 100C, the cracking rate can be increased. Double. After thermal cleavage, oxygen free radicals with specificity are stored at the end of the cleavage molecule.

(3) Efficacy of oxygen. The existence of oxygen will cause hydroperoxides in the depolymerization of vulcanized rubber, which will cause the molecular chain to be easily broken and accelerate the cracking rate. In addition, specific oxygen free radicals converted by cleavage can be re-fused. It will also make the cracking rate very slow. For vulcanizates containing double bonds on the main chain, the cracking rate is relatively slow. According to the classification, the basic decision is whether to renovate and the type of refurbishment. Then, the original product is tested for physical properties such as core type, tensile strength, and compressive strength. For those that can be renovated, peel off all the masking glue, and for those that need to be repaired, remove some of the masking glue. The detached conveyor belt is then ground and polished to remove the vulcanized rubber remaining on the belt core, remove the etched or damaged part of the belt core, apply glue, and dry it to cater for the white canvas that has been wiped, and then paste it on the satin Cover rubber. The tablet PC is then steam vulcanized or ultra-low temperature vulcanized, and then repaired to produce finished products. Our company also sells PVG Conveyor Belt, welcome to consult.
