3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Ultrafiltration membrane
It consists of a very thin epidermal layer that acts as a separation and a thicker supporting sponge or finger-like porous layer.
Hundreds to millions of membranes.
[GB/T.20103-2006, definition 5.1.1]
3.2
External pressure hollow fiber ultrafiltration membrane outside-inholowfiberultrafiltrationmembrane
The outer surface serves as a hollow fiber ultrafiltration membrane for separation.
3.3
Contact angle contactangle
When the droplet contacts the surface of the sample to be tested, the tangent of the gas, liquid contact surface of the solid, liquid and gas three-phase intersection and the surface of the sample to be tested form a clip.
Angle, as shown in Figure 1.
[HY/T 212-2016, definition 3.2]
