Lianyi polypropylene (PP) extruded biaxial geogrid is a widely used geosynthetic material designed to provide reinforcement in civil engineering projects such as road construction, soil stabilization, and embankment reinforcement. Ensuring the quality and performance of PP extruded biaxial geogrids involves rigorous testing and quality control measures. These measures are essential to verify that the geogrids meet industry standards and perform effectively in their intended applications.

Quality Control Measures

  1. Raw Material Inspection:
    • Standards: Manufacturer’s specifications and industry standards.
    • Procedure: The quality of polypropylene resin and other raw materials is inspected upon receipt. Tests include melt flow index, density, and impurity content to ensure consistency and quality.
  2. Production Monitoring:
    • Procedure: Continuous monitoring of the extrusion and stretching processes to ensure that the geogrid meets dimensional and mechanical property requirements. Parameters such as temperature, stretching ratio, and extrusion speed are controlled and recorded.
  3. In-Process Testing:
    • Procedure: Samples are taken from the production line at regular intervals for in-process testing. This includes tensile strength tests, aperture size measurements, and visual inspections to detect any defects or inconsistencies.
  4. Finished Product Testing:
    • Procedure: Comprehensive testing of the final product to ensure it meets all specified standards. This includes tensile strength, elongation, aperture stability, and durability tests.
  5. Batch Certification:
    • Procedure: Each batch of geogrid is certified based on the results of the testing. Documentation includes test results, compliance certificates, and traceability information.
  6. Storage and Handling:
    • Procedure: Proper storage and handling procedures to prevent damage or degradation of the geogrids. This includes protection from UV radiation, chemicals, and mechanical damage.
  7. Third-Party Audits:
    • Procedure: Regular third-party audits to verify compliance with industry standards and quality control procedures. Audits may include site inspections, review of test reports, and verification of manufacturing processes.
