2, by special micelle connecting gear, internal distinctive steam pipeline steams with steam outlet nozzle spray water
Gas.Micelle and air is isolated, it is ensured that the micelle of the condition of high temperature do not cracks, not oxygen with the steam of a certain amount of full high-temperature space
Change.Particularly steam outlet nozzle design, uses top arc shape to extend out structure, and beneficially steam quickly spreads, and strengthens water
Steam isolation effect.Quantitatively softening agent it is sprayed in the rubber powder of motion by fueling injection equipment and vaporizes so that it is uniformly admixing, full
Foot rubber powder softens, the needs of chain rupture；Particularly atomizer design, multiple oil spout pipelines carry out spraying softening agent from multiple angles,
Accomplish to cover comprehensively, uniformly spray；And spray bar uses unique 62 degree, 48 degree to be obliquely installed, can effectively ensure that spray area
Maximize.
3, the thick smelting method of special reclaimed rubber, makes rubber powder be placed in the high-temperature space of motion, meets and opens strand
Temperature-time requirement；Use the multiple thick smelting method of twice stirring, twice softening, twice desulfurization, thus it is big to be continuously finished micelle
Molecule cross-linked structure opening and stoping anti-process to short chain molecule structure, is greatly promoted properties of product.Improve and use
Effect.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope that the invention discloses, the change that can readily occur in or replacement,
All should contain within the scope of the present invention.Therefore, protection scope of the present invention should be with the protection domain of claims
It is as the criterion.
