             Key Points of RV Rubber Reviving Technique

            Ø  First, break the waste rubber on the open mill to 30 meshes, if the condition permits, break the waste vulcanized rubber on the rubber fine crusher to 40 meshes—60 meshes. The scorching rubber or soft vulcanized rubber can be mixed directly on the open mill.

            Ø  Dosage of the RV rubber reclaiming agent:

            100 parts by weight of all sulfur vulcanized rubber powder-2 parts by weight of RV2101

            The scorching rubber compound should add 0.5-2 parts by weight according to the scorching condition.

            Ø  The thinner the mesh of the waster rubber, the lower the Mooney viscosity of the revived rubber will be, and the broke elongation will be high, but has little thing to do with the tensile strength.

            Ø  The roll pitch of the open mill should be controlled within 0.150.25mm,it is recommended to measure the roll pitch by using lead wire passing through two rollers.

            Ø  The temperature of the roll pitch should be controlled at 5060; if the temperature is too high, the rubber will be softened, and the shearing force will reduce, which may affect the reviving effect.

            Ø  The best times of 40 meshes powder passing through the two rollers is 30 times, and if the times are too many, the Mooney viscosity is low, the tensile strength is increased, the break elongation is decreased and the energy consumption is big.

            Ø  The raw rubber (or raw compound rubber) and the softener should be added when the rubber powder has been rolled in the roller 20 times, and should not be added ahead of time.

            Ø  When reviving the rubber by 40 meshes tire rubber powder, if the condition permits, mix the tire rubber powder and the RV rubber reclaiming agent on the high-speed stirring machine for 2-3 min, and then lay it aside in cool places and the effect is rather good.

            Ø  The "revived rubber" can be kept for half a year, and if the Mooney viscosity increases, mill run the "revived rubber" on the open mill 3 times before using, so that the original state of the "revived rubber" can be restored.

            Ø  Our "revived rubber" no need to add any vulcanizing agent, accelerator, ageing resister, etc. when it is restored to the final compound rubber. When using the revived rubber, first mill the raw compound rubber on the open mill, and then add the revived rubber and mill together.

            Ø  30% of "revived rubber"+70% raw compound rubber production, the basic property of the production remains unchanged.

            30% of "revived rubber"+70% raw compound rubber production, the vulcanizing speed is fast so that the dosage of the additives can be reduced: the dosage of the accelerator and that of the sulfur can be reduced 20% respectively in "70% of raw compound rubber"
