The document describes a technique for reviving scorched rubber using RV rubber reclaiming agent. The technique involves cutting scorched rubber into particles and mixing it with 0.5-3 parts by weight of the reclaiming agent depending on the level of scorching. The mixture is then milled 10 times to restore the rubber's plasticity. The process uses mechanical and chemical methods to reclaim rubber waste through a crusher, conveyor and finishing the reclaiming.

RV reviving technique for scorched rubber
-Normal temperature and pressure
I. Technique requirement：
1. Materials –Scorched rubber waste
First, cut the self-vulcanized or scorching rubber into particles through mechanical
shearing, and then add RV rubber reclaiming agent. The dosage shall be determined
according to the scorching situation. The lightly scorching rubber can be revived with 0.5~1
part by weight, heavily scorching rubber added with 1.5~2 parts by weight, and completely
self-vulcanized rubber with 3 parts by weight (calculated in 100 parts by weight, the quality
part of the compound rubber). Attention shall be paid that the scorching rubber shall be sulfur
vulcanized series, and there are no effects for the rubber vulcanized by peroxide
2. Reviving process：
First, adjust the roll pitch of the open mill to 0.2-0.3mm, mill run the scorching rubber of 100
parts by weight and the reviving agent of the scorching rubber of 0.5-1 part by weight by the
open mill, and sheet after about 10 times, and the reviving is achieved. The customers can
adjust the amount of the reviving agent and times for mill running in accordance with the
scorching situation of the rubber.

Rubber crusher, used to crush the rubber into granular or net meshes, and then using the RV
tech conveyor to refine the rubber waste and reclaiming agent, the process can restore the
rubber plasticity by mechcano-chemical technique and finally finished the reclaiming
process.
