High Thermal Efficiency Two-layer Frame Plate Vulcanizing Machine - Used To Manufacture Rubber Fiberboard
Machine introduction:
1. Types of rubber fiber sheet vulcanizers
(1) Flat vulcanizer (intermittent vulcanization)
Applicable products:
Ordinary rubber sheets (such as anti-slip mats, industrial rubber sheets)
Insulating rubber sheets (for distribution rooms)
Oil-resistant, acid-resistant and alkali-resistant rubber sheets
Conductive/antistatic rubber sheets
Composite rubber sheets with fiber reinforcement layers (such as asbestos rubber sheets, canvas-reinforced rubber sheets)
Working principle:
Put the mixed rubber sheet (or fiber-reinforced rubber composite material) into the mold.
High pressure (usually 10-20MPa) is applied through the hydraulic system, and the heating plate provides temperature (140-180℃).
Maintain a certain time (5-30 minutes, depending on the thickness) to complete the vulcanization.
Equipment features:
Can produce a wide range of thicknesses (1mm~50mm).
Suitable for small batch and multi-specification production.
Multi-layer vulcanization table can be added (to improve efficiency).
Technical Parameters
Parameter | Typical Range | Explanation |
---|---|---|
Temperature | 140 - 180°C | For Natural Rubber (NR), it is usually 150 - 160°C. For EPDM, it can reach 170 - 180°C. |
Pressure | 10 - 20MPa | To ensure the rubber flows adequately and eliminate air bubbles. |
Vulcanization Time | 5 - 30 minutes | Depends on the thickness (e.g., for 5mm thickness, it takes about 10 - 15 minutes). |
Cooling Method | Natural cooling / Water cooling | To prevent deformation and improve dimensional stability. |
3. Special requirements for fiber-reinforced rubber sheets
If the rubber sheet contains a fiber-reinforced layer (such as canvas, nylon, polyester fiber or asbestos fiber), pay attention to the following during vulcanization:
Fiber pretreatment: Glue or dip is required to improve adhesion with rubber.
Vulcanization pressure: Higher pressure (15-25MPa) is required to ensure that the rubber penetrates the fiber layer.
Temperature control: Avoid excessively high temperatures that may cause fiber aging (such as nylon fiber temperature resistance ≤180℃).
4. Common Problems and Solutions
Problem | Possible Causes | Solutions |
Bubbles/Layering | Insufficient pressure, poor venting | Increase pressure, add venting grooves to the mold |
Uneven thickness | Uneven mold, poor fluidity of rubber compound | Adjust the parallelism of the mold, optimize the rubber compound formula |
Delamination between fiber and rubber | Untreated fiber or insufficient adhesion | Pre - coat fiber with adhesive, increase vulcanization pressure |
Rough surface | Mold contamination, uneven temperature | Clean the mold, check the temperature uniformity of the heating plate |
