Problems solved by technology
At present, there are few practical technologies and patents on the anti-burst pressure and compressive pressure of hollow fiber membranes, and most of the membrane manufacturers and scientific research institutions can only test the fracture of membranes in the testing process of membrane mechanical properties. Tensile Strength
However, the tensile strength at break of the membrane cannot completely objectively reflect the mechanical properties of the membrane under pressure, especially when filtering different media.
This causes large errors and unpredictable results during the application of the membrane

The invention discloses a hollow fiber membrane wire blasting-resistance pressure and compression-resistance pressure testing device and a method. The device comprises a control cabinet, a testing cabin, a first testing medium tank, a second testing medium tank and a data collection system. The testing cabin, the first testing medium tank and the second testing medium tank are respectively arranged in the side face of the control cabinet through supports, and the data collection system is connected with a pressure meter, an electromagnetic flowmeter, an electromagnetic valve and the control cabinet through pipelines. The first testing medium tank and the second testing medium tank are connected with an air pressure source. The method characterizes hollow fiber membrane wire blasting-resistance pressure and compression-resistance pressure mainly by monitoring of a medium pressure mutation inflection point. A membrane wire testing component is simple in manufacturing method, short in time, and capable of rapidly and accurately testing the hollow fiber membrane wire blasting-resistance pressure and compression-resistance pressure, simultaneously can control lifting speed of testing pressure, and can use testing media of different types to conduct testing. The testing device can record changes of pressure in the whole testing process and outputs a testing result through a display.
Description
technical field [0001] The invention belongs to the field of performance testing of hollow fiber membranes, and relates to a device and method for testing the anti-burst pressure and compressive pressure of hollow fiber membranes. Background technique [0002] With the deteriorating quality of water environment and rapid economic development, there is an urgent need for sewage resource technology to alleviate the shortage of water resources. Because the membrane separation process has the characteristics of high efficiency, energy saving, simple process, environmental protection, easy control, and low operating cost, it has been widely used in the field of sewage treatment. Among various forms of membranes, hollow fiber membranes have been widely used in sewage treatment, ultrapure water preparation, blood Dialyzer, seawater desalination, artificial lung, organic solvent dehydration, organic solvent mixing and other fields. [0003] In the actual application process, there...
