  test method 
  Different testing items require different testing methods, and commonly used methods include:
  Density detection: rapid measurement is carried out using drainage method or electronic density meter.
  Thermal conductivity testing: Determine the thermal conductivity of materials through steady-state plate method or transient heat flow method.
  Pressure resistance testing: Use a universal material testing machine to conduct pressure testing and evaluate the compressive strength of materials.
  Fire resistance performance testing: Conduct simulation experiments in high-temperature furnaces to observe the fire resistance integrity and thermal insulation of materials.
  Chemical composition analysis: Elemental analysis is performed using X-ray fluorescence spectrometer (XRF) or scanning electron microscope (SEM).
  Fiber diameter and distribution detection: Fiber morphology observation and measurement are carried out through microscopic imaging technology.
