SYSTEM AND METHOD FOR CONTINUOUSLY MANUFACTURING CURED MEMBRANES |
| 摘要 |
A method of continuously manufacturing a cured membrane includes continuously compounding and mixing a vulcanizable rubber composition in a mixing extruder while continuously removing gasses from the vulcanizable rubber composition during mixing with a vacuum. The vulcanizable rubber composition may be continuously extruded to form an extrudate, which may be continuously calendered to form a green membrane. The green membrane may be continuously cured, such as by a hot air conveyor curing system, to form a cured membrane. |

1. A method of continuously manufacturing a cured membrane, the method comprising:
charging rubber, filler, oil, and a curative to a mixing extruder; mixing the rubber, filler, oil and curative to form a vulcanizable rubber composition; subjecting the vulcanizable rubber composition to a reduced pressure; extruding the vulcanizable rubber composition to form a continuous extrudate; applying a compressive force to the extrudate to form a green membrane; and applying energy to the green membrane to form a cured membrane. |
