Description

Technical Field

[0001] The utility model relates to the field of curtain membrane testing, in particular to a curtain membrane bending durability testing tooling. Background Art

[0002] The curtain membrane is a hollow fiber membrane. Because the appearance of the hollow fiber membrane is similar to that of "door curtains" and other items, it is called a curtain membrane. The hollow fiber membrane is mainly made of PVDF material, with excellent antioxidant and anti-pollution properties. Using pressure as the filtration principle, it is usually used in the fields of sewage treatment, drinking water, and seawater desalination. The work of the hollow fiber membrane mainly takes filtration as the separation principle, with a filtration accuracy in the range of 0.005 - 0.01 μm. During operation, it uses an asymmetric microporous structure and a semi-permeable membrane medium, relying on the pressure difference on both sides of the membrane as the driving force, and filtering in a cross-flow manner, so that water flows into the membrane module, and impurities are filtered outside the membrane module. The hollow fiber membrane can effectively remove impurities such as particles, high-molecular organic substances, colloids, and bacterial cushions in water, and can achieve the purposes of separation, grading, purification, and concentration.

[0003] During the water treatment process, the curtain membrane will swing in the water. Over time, the membrane filaments or problems during the membrane sheet gluing may cause the membrane filaments to break at the glue injection connection of the membrane cassette. Therefore, in order to improve the membrane sheet quality, increase the anti-bending strength of the curtain membrane, and improve the reliability of the curtain membrane, it is usually necessary to conduct an anti-bending reliability test on the membrane filaments injected into the curtain membrane before leaving the factory. However, the traditional anti-bending test device has a narrow product adaptation range, poor versatility, and low convenience for testing curtain membrane sheets. Summary of the Invention
