VI. Process Flow Chart
EPDM Waterproofing Membrane Production Process Flow Chart
Weighing & Batching → Internal Mixing → Open Mill Mixing → Extrusion Forming → Continuous Vulcanization → Cooling & Setting → Cutting → Winding → Inspection & Packaging
Process Description:
Weighing & Batching: Precisely weigh EPDM rubber, carbon black, oils, and other compounding agents according to the formulation ratio.
Internal Mixing: Add weighed raw materials into the internal mixer for mixing, ensuring uniform dispersion of all compounding agents in the rubber.
Open Mill Mixing: Perform supplemental mixing and preheating of the internally mixed compound on the open mill, preparing it for the extrusion process.
Extrusion Forming: The preheated compound passes through the cold feed extruder and head to form a membrane blank of specified width and thickness.
Continuous Vulcanization: The extruded membrane enters the continuous vulcanization unit, completing the vulcanization reaction at high temperature to form a cross-linked structure.
Cooling & Setting: The vulcanized membrane passes through the cooling unit for rapid cooling and setting.
Cutting: The cooled and set membrane is automatically cut to the set length.
Winding: The cut membrane is wound into rolls of specified length via the automatic winding unit.
Inspection & Packaging: Quality inspection of finished membrane rolls, packaging and labeling of qualified products, preparing for shipment.
