Advantages of arched cover plates for fiberglass sewage tanks

Arch cover plate of sewage tank

After sealing the sewage tank with a fiberglass arch cover plate, it can effectively prevent environmental pollution caused by the evaporation of pollutants. Generally, a fiberglass arch cover plate is used to seal the sewage tank.

Introduction to raw materials of fiberglass arch cover plate for sewage tank:

Reinforcement material: glass fiber reinforced material;

Matrix material: specialized thermosetting resin with additives such as heat resistance, cold resistance, and chemical resistance

Auxiliary materials: flame retardants, reinforcing agents, flame retardants, gelling agents, and UV resistant agents, etc

Introduction to various parameters of fiberglass arch cover plate for sewage tank:

Technical parameters: tensile strength: not less than 200Pa; impact strength: not more than 20J/cm2; bending strength: not more than 150Pa; forming density: not more than 1800kg/cm3

Physical properties: Barcol hardness: ≥ 50 Roughness rate: 0.0084 Elongation at break: 0.8% Wear resistance: ≥ 99.98%

Poisson's coefficient: 0.3 Wear allowance: Å 1.5- Oxygen index: ＞ 36 Temperature resistance energy ⼒: -50~110 ℃

Flame retardant performance: in accordance with ASTM-E84 (flame retardant combustion rate less than 25)

Resistance to organic compounds: including methanol, alcohol, hydrogen sulfide, oil, etc

Introduction to the forming process of fiberglass arch cover plate for sewage pool:

Production process: mold sandblasting and casting, one-time molding;

Finished product composition: corrosion resistant layer, added layer, and weather resistant layer;

The special fiberglass arch cover plate of the sewage tank adopts a special structural form, which has good integrity after installation and can be left unused. It has good wind resistance, snow resistance, and can withstand maintenance loads. The cover plate has a uniform adhesive layer on the surface, with a smooth surface, no cracks, and uniform luster; The resin content of the cover plate is above 70% for the resin layer, 55% for the structural layer, and the curing degree of the composite material is not less than 80%; Observation windows and access doors can be reserved on the arched cover plate for easy maintenance without affecting the normal operation of the equipment.
