Filter element for magnetic slurry filtration
Compatibility test method
Subject content and scope of application
This standard specifies the compatibility test method of filter element for magnetic slurry filtration and a specified liquid. This standard is applicable to filter element for magnetic slurry filtration in the magnetic recording material industry. Method Summary
HG/T2353.4-92
Under given conditions, the filter element is immersed in a specified liquid and the change in filter element performance is tested. 3 Test equipment and test liquid
3.1 Test equipment
Glass container for test liquid and water bath for heating, 3.2 Test liquid
The test liquid adopts a single solvent or mixed solvent for preparing magnetic slurry, 4 Test procedure
4.1 Filter element immersion
Immerse the filter element to be tested in the test liquid,
Put the glass container containing the test liquid and the filter element in a water bath for water bath heating, and stop heating when the temperature rises to about 60℃. After the constant temperature is maintained for 72 hours, take out the filter element and let it dry. 4.2 Filter element performance test
After the filter element is fully dried, inspect the appearance and external dimensions of the filter element according to the technical requirements of HG/T2352, and measure the filtration accuracy of the filter element.
