HDPE Geomembrane Heat Welding: Field Procedure, Parameter Control and Seam Testing

The test tube is used to lock the temperature, speed and pressure and to form a closed loop record of the two-track tube, the extrusion tube, the test tube and the correction tube.

Steps to landing

  1. Clean connecting areasThe first is the removal of water, dust, oil and oxidation from the surface.
  2. Complete the testThe same batch of materials, equipment and environment are verified for stripping and cutting.
  3. Continuous connectionThe device is designed to be stable and to be unusually shut down immediately.
  4. Testing and correctionThe company is also responsible for the development of the new technology, including the development of new technology and the development of new technologies.

Acceptance points and common risks

  • The rain is not overThe water and steam will form channels and empty caves.
  • Just witnessing.The continuous surface does not represent the descent and cutting requirements within the aluminum.
  • No numbered recordsThe fault is not traceable to the same class or equipment.

Project judgments and procurement conclusions

The correct practice is to test the temperature of the mill directly from the article. The correct practice is to test the milling machine according to the thickness of the film, the surface temperature of the film, wind speed and equipment state to determine the parameters of the window. Long vertical preference for double track heat pumps, turning angles, patches and throughput nodes with the extrusion pumps; each pump must be dated, milling machine, operator and roll number.
