Technique process:
Brief Introduction of RV Reviving Process:
First, adjust the roller pitch of the open mill to the minimum(zero pitch), put 100 parts by
weight (10-40 meshes) of rubber powder or waste rubber leftovers and 2 parts
by weight of RV rubber reclaiming agent to the open mill, and mill for 10 min so that
they can be evenly blended; then adjust the roll pitch to 0.5 mm, add the processing
aid and compound rubber for 5 min mixing before sheeting. The roll temperature of the
open mill should be below 70℃. It is recommended to use the refining mill, which has
good effect and high efficiency; the whole process can be finished only in 10 min.
Using RV technique automatic folding machine can reduce the labor intensity with more
even mixing. This equipment can be customized by RVTECH.

Principle：
RV revived rubber technique is, through mechanical shearing, to make RV rubber reclaiming agent
wrapped evenly on the surface of the waste rubber powder particles and infiltrate into the rubber
powder particles by the wetting effect so as to reduce the bond energy of S-S cross-linking bond,
untie the S-S cross-linking bond effectively within a short time without destroying S-C bond and
C-C bond, thus make waste rubber restore its activity.
The rubber revived by RV rubber reclaiming agent can vulcanize without any vulcanizing agent
and accelerator. This kind of rubber is named as RVR revived rubber, (it is revived to the final rubber
compound, which is completely different from common reclaimed rubber), it restores the basic

property of the raw rubber, and if it is calculated in tensile strength, it can be restored to 50-85%
of the raw rubber. Using RVR alone to revive rubber products or to substitute 10-70% of the raw
compound rubber can reduce costs, guarantee the quality and increase the efficiency.
Reviving the scorching rubber by using less RV rubber reclaiming agent gets better effect.
RV revived rubber technique is exquisite, simple and non-toxic, with low energy consumption
and without hard labor intensity, which can be finished under normal pressure and temperature.
The Application Methods and Features of RVR Revived Rubber
RVR Revived Rubber is directly revived to final rubber compound, and can vulcanize
directly without adding any accelerator or vulcanizing agent. Compared wtih common
reclaimed rubber, it can save about 500-800 yuan/ton of additives when producing
finished products.
Using the RVR Revived Rubber alone can produce relatively low-grade products.
It is recommended to mix the RVR Revived Rubber with the raw compound rubber,
and the highest mixing rate can be 90%, to be adjusted by you accordingly.
Method of mixing with raw compound rubber:
First, add RVR to the open mill, mixing and mill running,
then add the raw compound rubber, mixing evenly and sheeting, and then have molding
and vulcanizing. If the vulcanizing speed is too fast in the process, reduce the dosage of
the accelerator and sulfur in the raw compound rubber.

C RVR Revived Rubber- produced by RV rubber reclaiming agent
It is with high anti-recovery, low permanent deformation and compression, high
rebound elasticity and low rolling resistance. Shortening the mix time can reduce
the temperature of mixing, calendering and extrusion; improve the tackiness of the
semi-finished products and the intensity of the rubber compound, and reduce the
extrusion expansion and contraction.
haracteristics of
Advantages of RV Rubber Reclaiming Agent:
a) RV rubber reviving technique is one way of rubber recycling by cutting S-S bond
without influencing S-C bond and C-C bond.
b) RV rubber reclaiming agent is safe, color stay, non-pollution, non-blooming and
has passed the inspection of RoHS and PAHs.
c) The processing time is short, and the work can be finished on the open mill in only
10-15 min. (Different kinds of waste rubber have quite different time differences.)
d) RV rubber reviving technique can be completed with the existing equipment of the factory.
e) All kinds of rubber waste, including the NR and SR or blending of NR and SR can be recycled.
f) It is effective to both mature rubber and semi-mature rubber compound.
g) It can vulcanize without adding any sulfur or accelerator and can save cost.

I) The process is completely without any air pollution and water pollution, and is in
accordance with environmental protection requirement.
j) The RV revived rubber products made by the RV rubber reviving technique are
completely odorless, tasteless and are widely used with high value.
k) RVS products make the use of the rubber powder expending; they can be used in the
production of desulfurizing rubber powder at normal temperature and can also be used in
modified asphalt rubber (CRMA)as well as rubber modified plastics, etc.
h) The wear resistance as well as ageing property of the rubber compound recycled
by the RV rubber reviving technique is better than that of any other reclaimed materials
(such as common reclaimed rubber, rubber powder and activated WRP, etc.).
