The composite manhole cover is crafted from fiber-reinforced thermosetting composite material, primarily utilizing unsaturated polyester resin as the matrix. This material is also referred to as bulk molding compound (DMC). The manufacturing process involves high-temperature and high-pressure one-step molding technology, resulting in a product with:
High Polymerization Degree:
Ensures enhanced material properties.
High Density:
Contributes to durability and strength.
Impact and Tensile Strength:
Offers resistance against physical stresses.
Additional Benefits:
Wear resistance
Corrosion resistance
No rust
No pollution
Minimal maintenance requirements
Structural Reinforcement and Security
The interior of the composite manhole cover is reinforced with a network of reticulated steel bars, particularly in areas subject to significant force. This design feature allows for effective pressure dispersion in the event of external impacts, ensuring the safety of both pedestrians and vehicles. Notably, the composite manhole cover does not contain substantial metal components; the reinforced skeleton's weight is less than 1/10 of the total cover weight. This results in minimal theft value, and the high strength of the cover makes it exceedingly difficult to remove the small steel bars, deterring theft attempts.
High Strength and Aesthetic Appeal:
The inorganic magnesite composite manhole cover offers a combination of high strength, low cost, and attractive appearance.
It can be customized in various colors and is easy to install and maintain.
The lack of recycling value effectively addresses theft concerns, making it a favorable choice for urban infrastructure.
Inorganic Synthetic Composite Manhole Cover:
This product is made from new high-strength inorganic synthetic materials, glass fiber, and a steel skeleton, positioning it as a mid-range option.
Its strength is comparable to stone-plastic manhole covers and can support over 40 tons of vehicle weight.
It performs better than concrete options and is suitable for applications requiring high technical standards.
Advantages Over Traditional Materials:
The option to use glass fiber reinforcement instead of steel skeletons enhances anti-theft properties, especially in the context of rising steel prices.
Its curing speed is significantly faster than that of fiber concrete, allowing for demolding within 8 hours. This efficiency enables up to three demolding cycles in a 24-hour period.
While requiring more molds than stone plastic covers, the need is only 1/6 that of fiber concrete manhole covers, reducing mold investment. With an annual output of 10,000 sets, only 10 molds are necessary.
