high efficiency metal oxide vulcanization rubber manufacture in india
Rubber Manufacture
Sand blasting is a metal surface mechanical treatment technology widely used in rubber production. The basic principle of sand blasting is to use sand, steel balls, glass beads, etc., with compressed air of 0.5~0.6MPa, and spray it onto the surface of the workpiece to be treated, and use high-speed jets of sand, steel balls or glass beads to remove the surface of the workpiece.

The NR has a high degree of unsaturation, and the non-rubber component in the composition promotes vulcanization, so that the amount of the accelerator is small and the vulcanization rate is fast. For HR, EPDM, etc. with extremely low unsaturation, high-efficiency and rapid accelerators such as TMTD, TRA, ZDC, etc. should be used together as the main accelerator, and thiazoles are the secondary accelerators.

Effective vulcanization system – Rubber Manufacture
In the vulcanized rubber network obtained by the above two combinations, the content of single bond and double bond accounts for more than 90%, and the network has little main chain modification. The utilization rate of sulfur in the vulcanization system is high, and it is called effective vulcanization system (EV).

Peroxide in the principle of vulcanization – Rubber
In addition to vulcanizing rubber, peroxide can also crosslink plastics, polyurethanes, and the like. Peroxide vulcanization coordination points. The amount of peroxide varies with the gum grade. For the cross-linking efficiency of rubber SBR (2.5). BR (10. 5), the amount of DCP is 1.5-2.0 parts; for NR (1.0), the amount of DCP is 2-3 parts.

Sulfur Cure Activators
Summary Vulcanization Activators are important rubber processing additives that activate sulfur cure and improve the efficiency of sulfur based cure systems. The most common activator is zinc fatty acid ester which is often formed in-situ by reaction of fatty acid with zinc oxide.

Vulcanization - an overview | ScienceDirect Topics
In continuous vulcanization modes for high volume productions, rubber article production is normally accomplished by extrusion, whereby the part is formed with a die, and the remainder of the process can be individually or a combination of curing processes such as the use of a shear head, a UHF line, hot air (oven drying method), fluid bed (using ballotini), or liquid curing medium (LCM).
